THE DISCLOSURE-LIKING RELATIONSHIP

Two experiments were conducted to investigate the effects of a perceiver's own disclosure on attraction for self-disclosing others. In Experiment 1, female undergraduates selected two topics and disclosed information on them to a confederate partner. This disclosure occurred either before or after the confederate disclosed information on three different topics that were either high or low in intimacy. Based on self-perception theory, it was predicted and found that intimacy of the subject's self-disclosure would be positively correlated with attraction for the confederate when the subject disclosed before her partner but not when she disclosed after her partner. A second prediction that subjects would be attracted toward a highly intimate partner only if they had previously disclosed was not confirmed. Instead, attraction for the confederate was greater when she had disclosed before the subject and when she had disclosed intimately. Experiment 2 varied the intimacy of the response of a partner to the subject's initial self-disclosure and whether this response dealt with the same topics or different topics. It was found that attraction was greater for an intimate than a nonintimate partner when topics for disclosure were the same. When disclosure topics were different, there was no significant difference in attraction for the intimate and nonintimate partner. Results are discussed in terms of their implications for the disclosure-liking hypothesis.     

Constraints on Analogical Mapping: A Comparison of Three Models

Three theories of analogy have been proposed that are supported by computational models and data from experiments on human analogical abilities. In this article we show how these theories can be unified within a common metatheoretical framework that distinguishes among levels of informational, behavioral, and hardware constraints. This framework clarifies the distinctions among three computational models in the literature: the Analogical Constraint Mapping Engine (ACME), the Structure-Mapping Engine (SME), and the Incremental Analogy Machine (IAM). We then go on to develop a methodology for the comparative testing of these models. In two different manipulations of an analogical mapping task we compare the results of computational experiments with these models against the results of psychological experiments. In the first experiment we show that increasing the number of similar elements in two analogical domains decreases the response time taken to reach the correct mapping for an analogy problem. In the second psychological experiment we find that the order in which the elements of the two domains are presented has significant facilitative effects on the ease of analogical mapping. Of the three models, only IAM embodies behavioral constraints and predicts both of these results. Finally, the immediate implications of these results for analogy research are discussed, along with the wider implications the research has for cognitive science methodology.     

A quasi-experimental investigation of message appeal variations on organ donor registration rates.

OBJECTIVE: Approximately 6,000 Americans die every year awaiting an organ transplant. Health promotion interventions may alleviate the shortage of viable organs by increasing the number of registered organ donors. This study is the first to evaluate the differential effectiveness of various organ donor messages in naturalistic settings. DESIGN: A 4 (Appeal)x4 (Exemplar)x4 (Location) counterbalanced quasi-experimental design was implemented. MAIN OUTCOME MEASURE: The behavioral outcome measure was the number of individuals who registered to be organ donors at computer kiosks. RESULTS: A number of significant main effects and interactions emerged. Most notably, of the 4 different appeals (counterargument, emotional, motivating action, dissonance), counterargument was by far the most efficacious, especially in academic-type settings (library, university, community college); the emotional appeal was most successful in hospitals. CONCLUSIONS: The findings from this study have implications for both organ donor investigations and health campaign research in general. Statistical interactions highlight the importance of evaluating multiple exemplars in multiple locations for each type of appeal when conducting health campaign research.
