Organizing Components into Combinations: How Stage Transition Works

This paper investigates the nature of transition between stages. The Model of Hierarchical Complexity of tasks leads to a quantal notion of stage, and therefore delineates the nature of stage transition. Piaget's dialectical model of stage change was extended and precisely specified. Transition behavior was shown to consist of alternations in previous-stage behavior. As transition proceeded, the alternations increased in rate until the previous stage behaviors were “smashed” together. Once the smashed-together pieces became coordinated, new-stage behavior could be said to have formed. Because stage transition is quantal, individuals can only change performance by whole stage. We reviewed theories of the specific means by which new-stage behavior may be acquired and the emotions and personalities associated with steps in transition. Contemporary challenges in the society increasingly call for transition to postformal and postconventional responses on the part of both individuals and institutions as the examples illustrate.     

Does language about similarity play a role in fostering similarity comparison in children?

Commenting on perceptual similarities between objects stands out as an important linguistic achievement, one that may pave the way towards noticing and commenting on more abstract relational commonalities between objects. To explore whether having a conventional linguistic system is necessary for children to comment on different types of similarity comparisons, we observed four children who had not been exposed to usable linguistic input - deaf children whose hearing losses prevented them from learning spoken language and whose hearing parents had not exposed them to sign language. These children developed gesture systems that have language-like structure at many different levels. Here we ask whether the deaf children used their gestures to comment on similarity relations and, if so, which types of relations they expressed. We found that all four deaf children were able to use their gestures to express similarity comparisons (point to cat + point to tiger) resembling those conveyed by 40 hearing children in early gesture + speech combinations (cat + point to tiger). However, the two groups diverged at later ages. Hearing children, after acquiring the word like, shifted from primarily expressing global similarity (as in cat/tiger) to primarily expressing single-property similarity (as in crayon is brown like my hair). In contrast, the deaf children, lacking an explicit term for similarity, continued to primarily express global similarity. The findings underscore the robustness of similarity comparisons in human communication, but also highlight the importance of conventional terms for comparison as likely contributors to routinely expressing more focused similarity relations.     

Dyadic interactions in accepted and rejected children

Forty same-sex dyads were separated into three groups (accepted, rejected, and mixed status) on the basis of their scores on the likability and rejection scales of the Pupil Evaluation Inventory [Pekarik, E.,et al. (1976).Journal of Abnormal Child Psychology, 4, 83–97]. These dyads participated in a 10-min videotaped interaction which was separated into three segments: waiting period, cooperative task, and conversational period. Observational recordings of six micro behaviors (talk time, gestures, gaze, smiles, orientation, and laughs), as well as ratings of physical attractiveness and speech volume (loudness) and observational counts of cooperation were obtained from these tapes. These data were subjected to a 2 (sex) × 3 (status) × 3 (segment) MANOVA, with sex and status as between-group factors and segment as a within-group factor. The results indicated a number of significant multivariate effects. Univariate tests for attractiveness, speech volume, and cooperation measures indicated a significant status effect for the variable of intensity. These results are interpreted in terms of the developmental literature on social behavior, as well as the data on face-to-face interactions provided by S. D. Duncan and D. W. Fiske [(1977).Face to face interaction: Research methods, and theory. Hillsdale, NJ: Erlbaum]. Suggestions for future research are offered.The authors wish to thank the principals, parents and children of Clinton Central Elementary, Frontier Elementary, and Western Elementary Schools for their help and participation in this project. We would also like to express our gratitude to Judith Conger, Patricia Moisan-Thomas, Judith Dygdon, and all other members of the research team who contributed their time and effort to this project.     

Validation of a component model of social skill with outpatient adults

Little social skills research has been generated from applied outpatient settings. The present study examined the relationship of behavioral social skill components to independent judges' social skill judgments. A secondary question was whether nonverbal components would demonstrate a curvilinear relationship to social skill ratings. Forty-two outpatient adults at a community mental health center were videotaped role-playing eight scenes (four commendatory and four refusal). Videotapes were viewed in random order by community members who rated the subject's social skill in the situation. Trained raters scored the videotapes on standard behavioral components. While both nonverbal and verbal components accounted for significant portions of unique variance, the percentage of eye contact was an overwhelmingly large contributor to skill judgments. No curvilinear trend was evidenced for the nonverbal components. The study extended prior findings with psychiatric inpatients into applied outpatient settings and indicated that a component social skills model is equally applicable with outpatient adults. The findings replicated with a second sample of outpatient adults.     

Was euclid an unnecessarily sophisticated psychologist?

A survey of the current state of multidimensional scaling using the city-block metric is presented. Topics include substantive and theoretical issues, recent algorithmic developments and their implications for seemingly straightforward analyses, isometries with other metrics, links to graph-theoretic models, and future prospects.Presented as the 1991 Psychometric Society Presidential Address. I am indebted to Doug Carroll, John Daws, Jan de Leeuw, Geert De Soete, Wayne DeSarbo, Eric Holman, Larry Hubert, Chingis Izmailov, Joe Kruskal, Rob Nosofsky, Akinori Okada, Roger Shepard, Auke Tellegen, and Wijbrandt van Schuur for many helpful comments on this research and to Yuko Minowa for bibliographic assistance. Doug Carroll's comments on an early draft were especially useful. Parts of this research were supported by a grant from AT&T to the University of Illinois. Some of the computational results reported here were obtained during the early 1970's at the Institute for Mathematical Studies in the Social Sciences at Stanford. Grateful acknowledgment is made to the Institute's staff and its Co-Directors, Richard C. Atkinson and Patrick Suppes.

Conceptual and linguistic representations of kinds and classes

We investigate the hypothesis that our conceptual systems provide two formally distinct ways of representing categories by investigating the manner in which lexical nominals (e.g., tree, picnic table) and phrasal nominals (e.g., black bird, birds that like rice) are interpreted. Four experiments found that lexical nominals may be mapped onto kind representations, whereas phrasal nominals map onto class representations but not kind representations. Experiment 1 found that phrasal nominals, unlike lexical nominals, are mapped onto categories whose members need not be of a single kind. Experiments 2 and 3 found that categories named by lexical nominals enter into both class inclusion and kind hierarchies and thus support both class inclusion (is a) and kind specification (kind of) relations, whereas phrasal nominals map onto class representations which support only class inclusion relations. Experiment 4 showed that the two types of nominals represent hierarchical relations in different ways. Phrasal nominals (e.g., white bear) are mapped onto classes that have criteria of membership in addition to those specified by the class picked out by the head noun of the phrase (e.g., bear). In contrast, lexical nominals (e.g., polar bear) specify one way to meet the criteria specified by the more general kind concept (e.g., bear). Implications for the language-conceptual system interface, representation of hierarchical relations, lexicalization, and theories of conceptual combination are discussed.
