What Does Competence Mean?

In recent decades, there has been growing interest in competence in Educational and Psychological Research and Human Resource Development Studies. One of the reasons for the popularity of competence research is the functional perspective of competence and the endeavor to further it. However, despite numerous studies on competence, the ambivalence of the concept of competence makes it hard to evaluate research findings. The aim of the present study is to make a contribution to the conceptual clarification of competence. We have made a systematic literature review and as part of it applied constructive analysis in the field of the concept of competence to postulate a new relation and broaden the conceptual theory of competence. We made our systematic literature review using the EBSCO host Library database and Google Scholar. Based on specific search criteria and on the sub-processes of the constructive analysis, we carried out the systematic review of the 10 identified definitions. Although we did not find a definition that we can employ according to our known use of other terms, we identified the meanings of construct, ability, and quality as plausible. Embedded within the etymological reconstruction, the logical conceptual systems of educational science and psychology and representative philosophical analyses, we state the new conceptual relation of competence.


Introduction
The concept of competence that White (1959) introduced into the scientific discussion of motivational psychology six decades ago, in thinking about drive-reduction theory and psychoanalytic-instinct theory, as a "motivational concept" (p. 318), is today increasingly a research topic in other disciplines such dies in the area of competence, there are only a few conceptual analyses of the concept of competence in studies. Among the studies focusing on competence there are some literature reviews (Fügemann, 2004;Hoffmann, 1999;Müller-Ruckwitt, 2008;Norris, 1991;Roeger, 2016;Short, 1985;Stoof et al., 2002;Weinert, 1999) of the many scientific uses of the terms "competence".
In Table 1, we compiled an overview of the essential results of the reviews of literature. Based on the initial analysis of these literature reviews, Table 1 shows as a result that the different definitions of competence are characterized by controversy, ambiguity, and contradiction. Although we can find some identical higher-order concepts, a broad range of different higher-order concepts and characteristic features characterizes the current state of research.
Considering the analyzed positions of competence, we can identify the following incompatible concepts that have been associated with competence: behavior vs. ability, inherited vs. learned, observable vs. non-observable, motivational vs. cognitive, quality vs. state, specific vs. general disposition, cognitivist vs. behavioristic construct, objectivist vs. constructivist view, construct vs. non-construct.
That the meanings of the term competence differ depending on the purpose for which it is used (Hoffmann, 1999: p. 275) contributes to the viewpoint that a generally valid definition of competence that would satisfy scientific criteria is not a realistic goal (Hartig, 2008). Stoof et al. (2002), who use the constructivist approach, confirm this perspective. For another reason, we can find a critical position towards the term competence: "…'competence' is the embodiment of a mechanistic, technically-oriented way of thinking which is normally inappropriate to the description of human action, or to the facilitation of the training of human beings". (Ashworth & Saxton, 1990: p. 24) Viewed from a philosophical perspective, Roeger (2016) also regards analysis of the concept of competence as impractical, because the concept is "technical" (p. 110).
The goal of the present study is to contribute to the conceptual clarification of competence by systematically reviewing the literature on the concept of competence. With the aid of conceptual analysis, the concept of competence will be explained. The outcome of this review should be to provide a framework of the higher-order concept and the differentia specifica of competence. A conceptual clarification of the concept of competence makes possible the construction of a coherent research program which is founded on an unambiguous and unified conceptual system.

Method
To analyze definitions of competence we made a systematic literature review. As part of it, we employed conceptual analysis to identify the higher-level concept and specific conceptual characteristics.
To do our systematic literature review, we used the EBSCO host Library (http://www.ebscohost.com/) database and additionally Google Scholar K. Schneider Table 1. Reviews of literature including the categories of definitions of the terms competence.

Source: Own analysis of reviews of literature. Psychology (https://scholar.google.de) to search for articles using the core search terms: competence, Kompetenz and compétence. We selected the EBSCO host Library, because this database has meta-data of more than 64,000 journals. Google scholar was used because it is regarded as the worldwide largest academic web search engine.
As a scientific method to clarify the concept, we employed conceptual analysis (Nuopponen, 1998). Its function is to clarify the contents of concepts, as well as their relations to other concepts (Nuopponen, 1998).
In the frame of conceptual analysis, Kosterec (2016: p. 222) uses three methods: Constructive Analysis, Detection Analysis and Retention Analysis. In Constructive Analysis, a new relation is postulated, or it is stated that "some already known relation holds among previously unrelated parts of the language" (Kosterec, 2016: p. 222), whereas Detection Analysis studies the existence of a conceptual relation in implicit conceptual theory. While in both methods the relations of a single conceptual network are studied, in Reductive Analysis the relation between two conceptual networks is analyzed (Kosterec, 2016).
We applied Constructive Analysis in the field of the concept of competence to postulate a new relation and broaden the conceptual theory of competence (Kosterec, 2016).
Following Kosterec (2016), Constructive Analysis consists of the following steps: • Specifying the initial conceptual background CB, • Formulating the conceptual problem P, • Stating the new conceptual relation R, • Formulating tests T of the conceptual relation R within CB, • Elaborating the new relation R by tests T respecting CB, and • If the relation R succeeds in tests, declaring it a part of CB.
The search procedure consists of three steps. In the first step, we selected databases referenced in the EBSCO host Library of the disciplines Business/Economics, Education and Psychology & Sociology. All available databases of the respective disciplines were included. To specify the advanced search, the following search criteria were set in EBSCO: Search within the 1) title 2) the full text of the articles, 3) and scholarly (peer reviewed) journals, 4) find all my search terms. In the second step of the search procedure, we selected literature referenced in Google Scholar. Finally, in the third step, we excluded from the conceptual analysis a) exact duplicates, b) articles with reference to specific competences such as for example communicative competence, and c) articles that did not include these types of information "Oberbegriff" (higher-level concept) of competence and "differentia specifica" after reading the abstracts resp. the papers.
We conducted these search and exclusion processes, which was done on 7 May 2019, with these inclusion/exclusion criteria (see Table 2).
Applying these inclusion and exclusion criteria, we reached a number of 10 K. Schneider Psychology  Step 3 Search excluding -exact duplicates, -specific competences, -lack of higher-level concept -lack of differentia specifica Total: -English: N = 9 -French: N = 1 Source: Own analysis. Psychology selected articles, of which nine were in English and one article in French. Based on the six sub-processes of the conceptual analysis, we conducted the systematic review of the 10 articles (see Table 3).

Specifying the initial conceptual background CB
To specify the initial conceptual background CB we etymologically derived the concept of competence and created a characteristic matrix with the higher-level concepts and the differentia specifica of competence in the definitions of the identified 10 articles.

Etymological Background
The word competentia goes back to the present participle active form of the verb competere (Eykmann, 2016: p. 34). The verb competere "… is a combination of the preposition used as a prefix 'cum' (= mit) and the stem word 'petere' (= to achieve, seek, strive for), thus 'competere' = collectively set out for a goal; coincide, come together". (Eykmann, 2016: p. 34) In a Latin etymological dictionary by Walde (1954) we find under the entry-petō, in the simplex form, the translated meanings: to try to achieve; to hurry, strive, request, demand; apply for.
"The intransitive 'competere' is used in the simple spatial sense (come together, go together, meet) and in the simple temporal sense (come together, coincide)". (Eykmann, 2016: p. 34) Behse (1976) observes that in Classical Latin the concept of competentia was used in the original sense of meet, come together. Derived from this basic meaning are as adjective or participle the substantively related meanings of suitable and appropriate (Eykmann, 2016: p. 34). "The substantive 'competentia', is documented only since the second century AD, is derived from the … intransitive use of the verb, and its somewhat rare use is limited to a few technical terms: in mathematics 'proportion', in astronomy 'constellation/conjunction', otherwise, e.g., the 'symmetry' of the body's limbs" (Eykmann, 2016: p. 34). In a Medieval Latin dictionary that includes Latin sources from the ninth to the end of the twelfth century, under the key word competentia are the meanings fit together, correspondence, appropriateness, suitability, fittingness (Schmidt, 1999). Hager & Gonczi (1996) Velde (1999) Jacques (2016) Weinert (1999) Source: Own analysis. Psychology The meanings in legal language range from the revenue of an ecclesiastical office that could be shown for the seventeenth century to judicial power in the eighteenth century, to responsibilities in the nineteenth century (Fügemann, 2004: p. 140). In the course of Germanization activities in the nineteenth century, the concept of Kompetenz was replaced by the concept of Zuständigkeit (responsibility, jurisdiction), so that today the concept no longer plays a role in the language of German legislators (Fügemann, 2004: p. 135).
Even if we can agree with Eykmann (2016) that the analysis of the word origin of Kompetenz (competence) leads to no unambiguous meaning, the etymological consideration of the substantive competencia provides clues to its conceptual characteristics (Müller-Ruckwitt, 2008). Figure 1 shows the satellite system 3 for the concept of competence. In the central node is the most important concept, competence, which is surrounded by related concepts (Nuopponen, 1998: p. 180).
The basic meaning of competence is to be seen in "coincide/coincidence": Two dimensions to be determined correlate. With the concept of competence states or characteristics in abstract form are designated as a fit between two dimensions. The type of fit is expressed in equivalence and suitability. These relationships show that the dimensions enhance each other or agree, respectively the one dimension is suitable for the other, necessary, appropriate.
Description of higher-level concept and differentia specifica of competence of definitions of 10 selected articles.
To develop the characteristic matrix we compiled the higher-level concepts and the respective differentia specifica of the selected definitions.
First, we extracted the terms of the higher-level concepts and the differentia specifica from each article for the respective terms competence and compétence.
Second, in a characteristic matrix (Nuopponen, 1998) the higher-level concept and the respective characteristics were entered. Table 4 summarizes the higher-level concepts captured with the aid of the characteristic matrix. We identified the high-level concepts of each definition and the respective differentia specifica of each higher level concept.

Formulating the Conceptual Problem P
The overview of the categories of definitions confirms that a consensus on the nature of the higher-level concept and the components is lacking (Fernandez et al., 2012). The literature reveals that not all authors define the characteristics, such as in the case of ability or capability, and that different characteristics of one definition display conceptual overlap, such as for example the characteristics Psychology situation and context. Some authors demarcate neither the generic concept nor the differentia specifica from concepts on the same conceptual level, as we find in the case of ability. A few higher-level concepts, such as, e.g., quality versus process, are complementary concepts. The analysis shows that the concept of competence is ambivalent.
Below we analyze the existence of the respective conceptual relations in implicit conceptual theory in the sense of Detection Analysis. We reviewed higher-level concepts and features of the identified definitions of Table 3 that were gained by systematic literature review. The first section groups together higher-level concepts that understand competence as ability/capability. We also analyze the understanding of competence defined as disposition in another section. The respective remaining sections discuss the higher-level concepts process, relation, quality or state of being and integration and combination of resources.

Competence as Ability/Capability
Eraut (1998) understands by competence ability to perform tasks and roles according to expected standards. Eraut (1998) specifies ability with the activities "to perform tasks and roles." "There are thus as many different abilities as there are tasks …" (Lohman, 2012: p. 87).
Eraut's (1998) method of defining competence cannot be reconstructed, because the author gives no arguments for the determining characteristics. The question arises of why the author chose roles or tasks and not, for example, "action types" (Thomann, 2010): Action types "arise from a concrete action through the deletion of one or more concrete components of the action, e.g., the agent …" (Thomann, 2010: p. 22). The "and" implies that not only tasks but also roles are to be performed in accord with expected standards. It is counterintuitive to exclude with the choice of the concept of tasks the creation of new things in the area of competence, because by tasks mental demands are understood, for the mastery of which methods are known (Dörner, 1976).
Ernaut (2016) clarifies competence through the action type "to perform tasks and roles according to expected standards". The quality of the ability is determined according to the extent to which performance standards were fulfilled.
Mulder (2011) defines competence as "capability to perform effectively". The author equates the concept of capability with that of ability: "The meaning of the concept is mostly defined as being able to perform effectively" (p. 12). This definition displays a nearness to that of White (1959), and Mulder (2011) (Thomann, 2010: p. 22). Psychology Mulder (2011) specifies the generic concept as an "integrated set of capabilities" (p. 13). This definition is vague, because it is unclear what we should understand by set and integrated. By competence is understood an integrated set of capabilities that arises from clusters of knowledge, skills and attitudes. That this cluster is a condition for effective performance is not explained. In addition, the conditioning factors are not a definitional characteristic of competence, since they give no answer to the question of what a competence is (Roeger, 2016). The definition is also vague insofar as the action type with the part components "problem solving", "realizing innovation", and "creating transformation", is not derived. "Knowledge", "skills" and "attitudes" are not coordinated concepts, as the arrangement implies: Attitudes are for Guilford (1959)  In both definitions, the entities that are called abilities are actions. The suitable expression would be "action type" (Thomann, 2010), for an essential characteristic is that it is not a matter of "… α can perform a specific action, …, but rather of such statements with which α is ascribed the ability to perform well actions of a specific sort" (Thomann, 2010: p. 22).
As, "the question: 'competent for (doing) what?' is essential to any competence definition" (Klieme et al., 2008: p. 7) and the entities which are called abilities are actions, the higher-level concept of ability is plausible.

Competence as Disposition
Not only Weinert (1999) but also  understand competence as a disposition. Klieme subordinates the disposition concept to a further higher-level concept, that of construct: "The expression emphasizes that with competences it is a matter of something 'constructed' by scientists that can at most be indirectly empirically interpreted … and that is not, like observational concepts, directly related to visible objects". (Schroeder-Heister, 1995: p. 445) The construct is deducible on the basis of observable indicators.
The conceptual clarifications of Weinert (1999) and  include no definition of the concept of disposition. Roeger (2016: p. 125) thinks a disposition refers to a characteristic "that is manifest only under specific conditions".
In the definition of  the concept of disposition is clarified in that it is learnable, contextualized and cognitive. The definition gives a conjunction of these three attributes. With regard to learnability, it can be affirmed with Roeger (2016: p. 157) that the concept of competence is trivialized by this characteristic, "… since then every person is competent who does not dispose of a competence, but can in principle learn it". The determination of the second necessary characteristic contextualized is vague, because it is unclear which external factors of the interaction to which the context per definition refers, how, K. Schneider Psychology e.g., place and time, must in what way be present, so that a disposition is contextualized. Likewise, with  cognitive characteristics distinguish the disposition. Weinert (1999) specifies the disposition as a performance disposition and operationalizes this as learned, cognitive and demand specific. A performance disposition leads under specific conditions to a manifestation of prototypical psychic processes that are distinguished by specific quality criteria. Weinert (1999) employs the concept learned in a more precise manner, because the area of application is limited: A competence is only present if it is learned. There is also a difference in the differentia specifica between contextualized and demand specific.
Due to the high level of abstraction, human dispositions such as, for example, perseverance and open-mindedness (Splitter, 2010: p. 216) are seen as vague in terms of their behavioral verification. It could be argued that it is not operable to further differentiate these forms depending on the context, because there might be as many dispositions as demands.
Following a definition of the theoretical perspective of situated cognition, ability is seen as "a joint property of the union of person and environment." (Lohman, 2012: p. 89) Against this theoretical background, the definition of competence appears to be circular, because the component of the environment already reflects, according to Snow (1994) who refers to Gibson (1979: p. 28), "the invitation, demand, or opportunity structure of a situation".
To mark the difference between disposition and competence, inspired by Tishman et al. (1993), we could ask: Does he philosophize? This question refers to the inclination to philosophize (Splitter, 2010), not to the competence.

Competence as a Process
According to Blömeke et al. (2015: p. 7) and Jacques (2016: p. 161), the concept of competence refers to a process ("processus") or a continuum. By a process is understood a directed process of an event (Carrier & Wimmer, 1995: p. 385), while a continuum means something cohesive and continuous. Blömeke et al. (2015: p. 7) specify a process with "connect" and Jacques (2016: p. 161) with "mediate". Even if the authors name the objects of the process, they are not precise: What does "connect" mean "between cognition and volition-affect-motivation on the one hand and performance on the other hand" or "mediate" specifically between the intentionality of individuals, their resources and those of their environment? Blömeke et al. (2015) present more a model of a continuum than one of a process showing that some dispositions of cognition or motivation are the prerequisites to acquire situation-specific skills needed for performance.
The concept of competentia cannot be understood as a process, because the suffix-ia as an abstraction of nominibus (Düntzer, 1879: p. 252) does not depict an event nominalization. If competentia is understood as a verbal abstraction, as a derivative of the participle (Eykmann, 2016: p. 34), there is a state or result Psychology nominalization (von Heusinger, 1998: p. 7), as in the case of appropriateness or of coming together. According to von Heusinger (1998), we cannot unambiguously semantically distinguish between characteristic and state nominalization: "Characteristics express attributes that are inherent or long lasting, while states are less enduring or stable. Formally in general we speak with the formation of adjectives of characteristic abstractions or characteristic nominalizations and with the formation of verbs of state abstractions or nominalizations" (von Heusinger, 1998: p. 4). Hager and Gonczi (1996: p. 16) define competence as a relation between abilities/capabilities and the completion of a task. The ascription of an ability that an "… agent α [can] exactly then perform actions of type h, if under such circumstances that are suitable for performing actions of type h, α can normally successfully perform actions of type h" (Thomann, 2010: p. 22) is related to the result of a concrete task. If the normally successful performance of actions of a specific type is related to that of a specific action of that type, then the second relatum would impermissibly be a component of the concept of the former.

Competence as a Relation
The concept of relation, whose higher-level concept is that of structure, designates a relation or a relationship among several objects, an entity or event and one or more other entities or events. Since the authors make no statements on the character of the highly complex relation, the specification of this relation remains vague. It is moreover unclear whether the characteristics abilities and capabilities are connected with a conjunction or disjunction. In addition, Hager and Gonczi (1996) do not specify the difference between ability and capability. If one defines a relational concept, it is to be defined through reference to its relata, which was not done here. The under-specification of the definition also applies to the definition by Velde (1999: p. 443), who defines competence as a conception and relationship of work. The concept is defined by two higher-level concepts with different meanings that are neither derived nor defined.
With the characteristic of the relation, the concept of competence cannot be sufficiently defined, since no answer can be given to the question of what competence is.

Competence as a Quality or State of Being
From the view of a thesis by Short (1985) that competence is a quality or state of being, it can be seen that the definition of the concept through the disjunction-linked unreconstructable higher-level concepts of quality or state of being as the character is under-determined, since neither the characteristics of state of being nor quality are defined, nor is it clear when a state and when a quality is present.
The concept of competence is not made more precise, because Short (1985) introduces two incompatible higher-level concepts in the definition: While the state is affected by circumstances, quality is stable over time. "States are observed K. Schneider Psychology behaviours including reports of experiences that typically refer to a day or a few assessments during a day" (Asendorpf & Motti-Stefanidi, 2018: p. 168). Short (1985: p. 5) himself sees the challenge in the holistic conceptualization, as it has to be understood in terms of the quality and not the sub-features of competence.
If a state typically refers to a period of a day, then it is not an educationally meaningful category. Fernandez et al. (2012) defines competence as a behavior of integrating and combining internal and external resources. The definition is under-determining, because the object of the activity, the resource is not determined. In addition, the actions of integrating and combining, which are not disjunctive, are neither theoretically derived nor specified. The authors see a further enhancement of the conceptual characteristic in naming the purpose of the activity and the resources: Competence is present when combined and integrated resources are prepared for an action. Since the suffix-ia (in competentia) does not permit deriving a behavior from the word competence, the higher-level concept of behavior is inappropriate.

Competence: Integration and Combination of Resources
The analysis of definitions shows that it is not a trivial aspect to find the higher-level concept of the concept of competence and its specific difference. For theoretical concepts it holds that depending on theoretical perspective, the theoretical presuppositions of the definition are different.

Stating the new conceptual relation R
Embedded within the etymological reconstruction, we refer to the logical conceptual systems of educational science and psychology and to representative philosophical analyses to state the new conceptual relation of competence.
The etymological reconstruction produced the result that with the concept of competence states or characteristics in abstract form are designated as a fit between two dimensions that complement or match each other, or respectively that the one dimension is suitable, necessary or appropriate for the other.
We were able to show that certain relations competence as a process competence as a relation competence as a state competence as integration and combination of resources don't hold among concepts of the etymology and the language of educational science and psychology. Based on the logical conceptual systems of educational science and psychology and against the background that some relations between the concepts were not clarified within the definitions, we came to a preliminary result: The following meanings of the concept of competence against our explained theoretical presuppositions of the definitions are plausible: construct, quality, and ability.
(R) Competence for performing domain-specific actions of type h is the cognitive ability to normally successfully perform domain-specific actions of type h under circumstances that are suitable for domain-specific actions of type h.
The concept of ability which is the higher-level concept of competence was defined with reference to Thomann (2010).

Formulating tests T of the conceptual relation R within CB
The following tests were carried out to examine the proposed operational definition: • Linguistic usage is examined for the proposed definition.
• In order to clarify the structure of the substantive conceptual system it is analyzed whether the higher-level concept and the differentia specifica are substantively unambiguous.
• In order to identify logical errors, it is examined whether 1) higher-level concepts are logically related to other concepts on the same level and 2) concepts on the level of the differentia specifica that are suspected to be coordinated are coordinated.

Elaborating the new relation R by tests T respecting CB
The linguistic and scientific usage shows that the concept of competence is a relational concept, competent for (doing) what , which has an inherent reference point. The reference to its relation must be defined. Together with the etymological derivation goes that relational concepts are mostly verbal abstractions or abstractions from adjectives.
Because the entities which are called abilities can only be individuated through reference of types of actions (Thomann, 2010: p. 22), the higher-level concept of the definition of competence (competent for doing what) is accordingly that of ability. As a definition for the concept of practical abilities, Thomann (2010: p. 22) proposes the following: "An agent α can exactly then perform actions of type h, if α can normally successfully perform actions of type h under circumstances that are appropriate for performing actions of type h".
Thomann also transfers the operational definition to cognitive abilities, because the difference between mental and non-mental abilities is "that the realization or respectively performance of the former requires no bodily activity" (Thomann, 2010: p. 41). "Mental action types appear to be partially characterizable through their success criteria, as well as for the circumstances appropriate for their realization, just as are action types whose realization contains bodily activity" (Tho-K. Schneider Psychology mann, 2010: p. 41). Thomann's definition (2010) will be adopted here for the concept of ability.
As we have already established above with Thomann (2010), in the case of ability it is not a matter of a specific action, but rather of an action type h which forms the inherent reference point of the relational concept of competence.
Actions can refer to a single performance of an action or a group of actions.
The unity of an action consists in that individual performance or group of actions have one and the same purpose or respectively goal.
Referring to natural language, typically the concept of competence is not generally used. The following examples illustrate this linguistic usage: Linda disposes of mathematical competences. John is competent in philosophy. According to this usage and to philosophical analyses, the concept of competence refers to an area, a specific subject (Roeger, 2016), to a domain. We follow Hirschfeld and Gelman (1994: p. 21) to define the term domain: "a domain is a body of knowledge that identifies and interprets a class of phenomena assumed to share certain properties and to be of a distinct and general type".
Circumstances are appropriate precisely "if a failure cannot be excused by reference to unfavorable conditions" (Thomann, 2010: p. 24). Various types of action require different circumstances for their realization (Thomann, 2010).
The concept of normalcy is likewise a relative concept. It refers to the reliability of successful performance, because abilities do not offer any success guarantee (Thomann, 2010: p. 26). "When an action is normally (italics in original -K.S.) carried out successfully, it thereby does not seem to be susceptible to quantification, but rather to vary from one action type to another" (Thomann, 2010: p. 27).
The higher-level concept of ability is logically related to other concepts located on the same level. For example, Guilford (1959: p. 9) subdivides all personality characteristics into classes with the following personality domains: Physiology, needs, interests, attitudes, temperament, abilities and morphology. Neyer and Asendorpf (2018) subsume under the construct of ability intelligence, creativity, social and emotional competence. The concepts of intelligence and social competence are located on the same hierarchical level, although they have different conceptual ranges. Even if these four abilities are demarcated in everyday psychology, clarity is lacking about some constructs, such as for example creativity (Neyer & Asendorpf, 2018) and criteria of classification.
In contrast to Neyer and Asendorpf (2018), we understand competence like ; occasionally Weinert, 1999) as cognitive ability.
We exclude motivational, volitional and emotional components from competence. Roeger (2016) argues in this regard that free will and motivation with its action grounds should be protected from pedagogical influences. It is counter-intuitive to deny someone has competence, if they have no desire to play the piano. Motivation and volition enhance competence so that performance comes about, they do not however constitute competence (Roeger, Psychology 2016). Ability as a higher-level concept is subdivided at least into cognitive and practical ability (cf. Thomann, 2010). The element of the already made division of cognitive ability is dichotomously subdivided on the basis of the essential characteristic of domain specificity into the sub-concepts of domain specificity and domain-non-specificity. The subsumable concept of competence comprehends all characteristics of the concept of cognitive ability and additionally as specifying characteristic domain specificity. For the concept of cognitive ability that is distinguished by a domain-non-specificity we have so far not found any suitable concept. The concepts are coordinated, because in contrast only a classificatory criterion was simultaneously employed on the same level of abstraction of the logical conceptual system (Peltoniemi, 2007: p. 254).
In contrast to the philosophical analysis of Roeger (2016), we do not use as a higher-level concept of competence that of skill ("Fertigkeit"): With reference to action regulation theory according to Hacker (1998), for example, skills represent action on the level of senso-motoric regulation.

If the relation R succeeds in tests, declaring it a part of CB
As a newly postulated relation R succeeded in the previously conducted tests, we have made it part of the conceptual background (CB).

Discussion and Conclusions
Following the constructivist viewpoint (Stoof et al., 2002), there may be no objective criteria in selecting a definition. Accordingly, competence is conceived as a construct. However, the etymological reconstruction, the logical conceptual systems of educational science and psychology and representative philosophical analyses provide a framework from which to derive the new conceptual relation of competence: Competence for performing domain-specific actions of type h is the cognitive ability to normally successfully perform domain-specific actions of type h under circumstances that are suitable for domain-specific actions of type h.
The higher-level concept of competence is ability, which refers to cognitive ability and is distinguished by domain-specificity. The concept of ability is logically related to other concepts located on the same level. We differentiate cognitive ability at least from practical ability and specify the cognitive according to domain-specific competence, and domain-non-specific ability. These two sub-concepts are coordinated, because they are only distinguished by the criterion of domain-specificity.
The etymological reconstruction produced the result that with the concept of competence characteristics in abstracted form are designated as a fit between two dimensions: in the case of competence, it is a matter of a coming together as the equivalent of a normally successful performance of a type of state changes (ability), on the one side, and the changes of state (demands) set from outside to Psychology be brought about, on the other. By actions Thomann (2010: p. 147) understands "state transitions (italics in original-K.S.) whose occurrence is directly attributable to an agent". Thereby, it is irrelevant for Thomann (2010: p. 147) "whether the state changes actually are the concrete actions or are merely brought about by them".
The results we have summarized have interesting implications for theories of competence from the perspective of educational science. The innovative way of defining the concept of competence proposed within this study lays a foundation for operationalizing the construct of competence. From the functional-psychological viewpoint competence focuses on the ability of a person to manage demands. However, the results of this study would suggest that competence also fulfills a purpose of development. Agency succeeds through domain-specific learning: Leslie (1994) showed this effect for early childhood. It can be demonstrated that the development of competence reinforces agency as a disposition.
The unity of an action consists in that individual performances of a group of action types have one and the same purpose. It remains, with Thomann (2010: p. 42), to examine "whether for every cognitive ability k there is a number H of-practical or mental-action types, so that an agent must include every type of action from H in his abilities in order to also have mastered k".
Since the concepts appearing in the definiens must be more elementary than the definiendum, the question arises of how the concept of domain-specificity can be defined in a more elementary way.
Understanding ability as situated within an interactionist theoretical perspective (Snow, 1994) means that interest, attitudes, needs, are likewise to be demarcated as situated in a further step against non-situated characteristics like physiology and morphology. From an interactionist point of view, domain-specificity is a "joint property of the union of person" (Lohman, 2001: p. 89) and phenomenon.
We see a limit of our conceptual framework despite the contradictory opposition of domain-specific and domain-non-specific in the empirical gradual approach on the level of differentia specifica. This conceptual analysis is far from final. However, we believe that this framework is useful for analyzing the concept of competence.
