On the adequacy of prototype theory as a theory of concepts

Prototype theory construes membership in a concept's extension as graded, determined by similarity to the concept's “best” exemplar (or by some other measure of central tendency). The present paper is concerned with the compatibility of this view of concept membership with two criteria of adequacy for theories of concepts. The first criterion concerns the relationship between complex concepts and their conceptual constituents. The second concerns the truth conditions for thoughts corresponding to simple inclusions.     

Note on the mathematical theory of interaction of social classes

In continuation of previous studies, the interreaction of two social classes is investigated from a somewhat different point of view. An exchange of results of activities of the two classes is considered, and a mathematical approach is outlined based on the use of such psychological concepts as the satisfaction function.     

Self-disclosure and liking: An integration theory approach

Integration theory models predict that sequences increasing or decreasing in intimacy should have less impact on attraction than constant intimate or nonintimate disclosures. Male and female subjects (N= 159) conversed with a videotaped confederate. Each confederate relayed six disclosures in one of five intimacy sequences: increasing, constant high, decreasing, constant low, and random. The confederate either had a choice of topics and sequence or they were imposed. Substantial support was found for integration theory models. The constant high disclosers by choice were liked more than their no-choice controls and the constant low disclosers by choice were disliked more than their no-choice controls. The mixed sequences (increasing, decreasing, and random) produced no significant differences.     

Towards a theory of the integration of the Other in representation

In this article, the author tries to uncover the elements of a theoretical model which would take into account the psychic transformations necessary to facilitate the emergence of representation. Toward this end, he firstly relies on Jung's notion of the archetype and Freud's idea of hallucinatory wish fulfilment, which he reconsiders in the light of the writings of Fordham (de-integration and re-integration of the primary self), and of Jean Laplanche (primary seduction), and linking it to the model based on chaos theory as developed in physics. He thus concludes that under the influence of primary seduction, the archetype is able to become a veritable, strange psychic attractor, enabling the determining factor of the instinctual axis of the archetype to open up to the possibility of symbolization, a necessary underlying feature for the occurrence of subjectivity. He ends his argument with a brief clinical vignette which illustrates the effect of openness to the psychic unknown constituted by primary seduction in the transference.     

Statistical analysis of fuzzy-set data from neuronal networks

In this study, we describe the process of transforming neuron polarization values that meet the assumptions of ratio data into ordinal data. This is a crisp-to-fuzzy set transformation. A computerized simulation of the application of this process is discussed and nonparametric methods of analyzing fuzzy-set data are presented.     

Playgroup attractiveness studied with information integration theory

Playgroup attractiveness was studied in two critical tests of information integration theory. In Experiment 1, the ratio of good to bad members in the group, and the number of toys available to the group, were varied in a 4 × 4 factorial design. The results obeyed the parallelism prediction of the theory, thereby indicating that group attractiveness was a sum or an average of the two given pieces of information. Experiment 2 provided a critical qualitative test between the adding and averaging hypotheses. The results eliminated the adding rule, supported the averaging rule. These results illustrate the potential power that integration theory provides to the experimental study of group attractiveness in children.     

Evidence for an integration theory of visual masking

When letters are superimposed upon a pattern of black and white squares, they are easier to identify when the pattern is regular than when it is random. If backward masking consists of the superimposition of a masking pattern upon the decaying visual trace of a target display, a regular pattern should be less effective as a backward mask than a random pattern. This was found to be so for both multiple-letter and single-letter displays. This result is predicted by an integration theory of visual masking but not by an interruption theory.     

Personality integration: A synthesis of the parts and wholes of individuality theory

Individuality theory views the total psychological system or personality as an organized complexity which is partitioned into six major systems—sensory, motor, cognition, affect, value, and style. Each of these systems is, in turn, describable in terms of its subsystems and their components. Individuality is captured via the concept of multivariate personality type, which includes both profile and temporal characteristics. Organism-environment interactions are handled via the basic system circuit. This circuit involves an information input from the environment, a norm against which inputs are compared, and outputs which feed back into the external environment. Normative match refers to the degree of alignment between a specifiable norm (i.e., a psychological construction such as a goal or a purpose) and the environmental input. We refer to norm-input matches as assimilation. In the case of mismatches, accommodation is required via feedback mechanisms. Whereas normative matching is focused on external interactions between the organism and the environment, template matching is focused on internal processes of the psychological suprasystem. Thus, template matching refers to the degree of alignment between the profile and temporal aspects of a specifiable situation and personality type. Template matching involves specifying the details of central processing—the integrative role of the style and value systems, the transformation processing of the cognitive and affective systems, and the coding role of the sensory and motor systems. Suprasystem functioning involves both internal (i.e., template matching) and external (i.e., normative matching) processing simultaneously. Thus, molar psychological constructions, such as worldview and life-style, are the products or outcomes of the integrative processing of the style-cognitive and value-affective systems respectively. When suprasystem norms are functioning assimilatively we are describing periods of personality stability. When suprasystem norms are functioning accommodatively we are describing periods of personality change. The most encompassing indicator of personality integration at a given moment     

Eclecticism, integration and comprehensiveness in counselling theory and practice

A trend toward eclecticism and integration amongst counsellors and others is described. This is mainly prompted by the demands of practice. Eclecticism emphasises 'borrowing freely from various sources' while integration emphasises 'combining parts into a whole'. Integration can be either horizontal, within a theoretical position, or vertical, between theoretical positions. Four models of eclecticism and integration are presented: single theoretical position; supermarket eclectic; eclectic theory-integrative practice; and integrative theory and practice. Neither eclecticism nor integration guarantees comprehensiveness. Some dimensions of a comprehensive theoretical position are described. The lack of a sound, comprehensive and integrative theoretical position, focused on the developmental needs and problems of living of the vast majority of people, has negative implications for both counselling and counsellor training.     

Favourableness of leadership situations studied with information integration theory

In Fiedler's contingency theory, situation favourableness for leader depends upon three situational variables — Group Atmosphere, Task Structure and Position Power. Each variable is dichotomized as high or low to define a 2 × 2 × 2 factorial cube with eight octants, and correlations between leadership style and effectiveness are plotted against the octants. To place these octants along a one-dimensional scale of favourableness, Fiedler assumes that Group Atmosphere is most important and Position Power is least important, and that the situational variables combine according to an adding rule. In four judgmental experiments conducted during different periods of national emergency in India, favourableness of leadership situations was studied with the methods of Anderson's information integration theory. Results indicated (a) that relative importance of situational variables changed across situations, (b) that situational variables were averaged in judgment of situation favourableness, and (c) that spacing of octants on the horizontal axis according to their functional measurement values generated a considerably better bow-shaped curve for correlation between leadership style and effectiveness than was obtained with Fiedler's octant scale. Judgmental experiments seemed to have great potential for providing a more analytic approach to further work on contingency theory and leadership behaviour.
