Why stereotypes don't even make good defaults

Many concepts have stereotypes. This leaves open the question of whether concepts are stereotypes. It has been argued elsewhere that theories that identify concepts with their stereotypes or with stereotypical properties of their instances (e.g., Rosch, E. (1978). Principles of categorization. In E. Rosch & B. B. Lloyd (Ed.), Cognition and Categorization. Hillsdale, NJ: Lawrence Erlbaum Associates; Smith, E. E., Medin, D. L. (1981). Categories and Concepts. Cambridge, MA: Harvard University Press.) fail to provide an adequate account of the compositionality of concepts (Fodor, J., Lepore, E. (1996). The red herring and the pet fish: Why concepts still cannot be prototypes. Cognition, 58, 253-270.; Fodor, J. (1998). Concepts: Where cognitive science went wrong. New York, NY: Oxford University Press.). This paper extends this argument and reports an experiment suggesting that participants do not assume, even as a default strategy, that complex concepts inherit the stereotypes of their constituents. Thus propositions such as "Baby ducks have webbed feet" were judged to be less likely to be true than propositions like "Ducks have webbed feet." Moreover, manipulation of the type and number of noun phrase modifiers revealed a systematic departure from the unmodified noun's stereotype both with the addition of stereotypical modifiers ("Quacking ducks have webbed feet" versus "Ducks have webbed feet") and with the addition of a second modifier ("Baby Peruvian ducks have webbed feet" versus "Baby ducks have webbed feet"). Thus, in the general case the stereotypical properties of a head noun are systematically discounted when that head noun combines with modifiers. This effect represents a general principle of conceptual combination that argues against the inheritance of stereotypical features of concepts as a default strategy. Instead, we advocate a model of conceptual combination where concepts remain inert under combination, supported by a separate machinery that introduces pragmatic and knowledge-dependent inferences.     

The description of gay and lesbian families in second-parent adoption cases

Lesbians and gay men are turning to the courts to recognize their family relationships. In this article every reported court decision where a lesbian or gay couple has successfully completed a second-parent adoption is reviewed to analyze the presentation and judicial analysis of the petitioning parties in conjunction with the current debates within family theory. Traditional family theorists argue that the contemporary family is in transition but will always be recognizable as the traditional family; postmodern theorists argue that the traditional “family” is a fiction. Results from this study indicate that judges in second-parent adoption cases rely on a traditional definition and vision of the family in evaluating the gay and lesbian petitioners before them. © 1998 John Wiley & Sons, Ltd.     

Truthiness and law: Nonprobative photos bias perceived credibility in forensic contexts

Nonprobative but related photos can increase the perceived truth value of statements relative to when no photo is presented (truthiness). In two experiments, we tested whether truthiness generalizes to credibility judgments in a forensic context. Participants read short vignettes in which a witness viewed an offence. The vignettes were presented with or without a nonprobative, but related photo. In both experiments, participants gave higher witness credibility ratings to photo-present vignettes compared to photo-absent vignettes. In Experiment 2, half the vignettes included additional nonprobative information in the form of text. We replicated the photo presence effect in Experiment 2, but the nonprobative text did not significantly alter witness credibility. The results suggest that nonprobative photos can increase the perceived credibility of witnesses in legal contexts.     

A Review of the Evidence for a Biological Basis for Snake Fears in Humans

The Psychological Record - Three types of evidence are considered for the view that the propensity of humans to fear snakes is derived from our evolutionary history. It is argued that findings from...     

Intimacy, identity and status: Measuring dating goals in late adolescence and emerging adulthood

Individuals?? goals can direct their own social behavior and development. We extended and validated a social dating goals measure (SDGS-R) to assess identity, intimacy and status goals, and compared goals by age, gender, sexual orientation and romantic status. Participants were 121 adolescents and 249 emerging adults (age M?=?20.6). The expected 3-factor structure of the SDGS-R was found and confirmed (18 items). Identity, intimacy and status goals had small correlations with each other and analyses validated the meaning and uniqueness of each goal. Participants reported more identity and intimacy goals than status goals. Intimacy goals were more prominent among older compared to teenage participants and those with a partner rather than without one. Females reported more identity dating goals than males. There was no difference in the goals of same-sex and other-sex attracted youth. The availability of the SDGS-R will allow further study of romantic development and relationship functioning.     

Anxious and Nonanxious Children's Face Identification

The impact of stress on children's face identification is not well understood, partly because of the ethical and methodological challenges posed by this line of research. In the present research, such challenges were addressed by having 4‐year‐old and 5‐year‐old children (n = 80) participate in swimming lessons that were anxiety provoking for some, but not all, children. Information processing conditions were also manipulated by varying event frequency and retention interval. Children's identifications were examined after both a short (1.5–4 weeks) and long (1 year) delay. Anxiety was largely unrelated to the accuracy of children's swimming instructor identifications; however, after a long delay, anxiety had a negative effect on correct line‐up rejections. In addition, the confidence–accuracy relation was influenced by the quality of the information processing conditions but only after a short delay. Implications for child witnesses are discussed.
