The experimental psychology of attitude change and the tradition of classical rhetoric

Social psychologists might be surprised to learn that their discipline has been cut off from a vast and ancient family tree. The study of attitude change in the context of experimental social psychology began around 1918. It developed into a defined discipline in the 1930s and 1940s, particularly through the work of Carl Hovland and his associates. Unlike earlier specialties in experimental psychology, social psychology emerged well after the 19th-century split between psychology and philosophy in college curricula. Before this period of growth in empirical teaching and practice, the study of persuasion in classical rhetoric was a bedrock of higher education for more than 2000 years. Because of social psychology's late development in empirical science, there is a historical disconnect between experimental social psychology and its ancient philosophical counterpart, classical rhetoric. This article demonstrates similarities and differences between Hovland's findings and the theoretical groundings of classical rhetoric. We suggest areas where modern social psychology might benefit from a look at the older, more holistic theories of the art of rhetoric.     

Source-monitoring training: toward reducing rater expectancy effects in behavioral measurement

The authors developed a source-monitoring procedure to reduce the biasing effects of rater expectations on behavioral measurement. Study participants (N = 224) were given positive or negative information regarding the performance of a group and, after observing the group, were assigned to a source-monitoring or control condition. Raters in the source-monitoring condition were instructed to report only behaviors that evoked detailed memories (remember judgments) and to avoid reporting behaviors based on feelings of familiarity (know judgments). Results revealed that controlling raters' response strategy reduced (and often eliminated) the biasing effects of performance expectations. These findings advance our understanding of the performance-cue bias and offer a potentially useful technique for decreasing rater bias.     

Suppositions, extensionality, and conditionals: a critique of the mental model theory of Johnson-Laird And Byrne (2002)

P. N. Johnson-Laird and R. M. J. Byrne proposed an influential theory of conditionals in which mental models represent logical possibilities and inferences are drawn from the extensions of possibilities that are used to represent conditionals. In this article, the authors argue that the extensional semantics underlying this theory is equivalent to that of the material, truth-functional conditional, at least for what they term "basic" conditionals, concerning arbitrary problem content. On the basis of both logical argument and psychological evidence, the authors propose that this approach is fundamentally mistaken and that conditionals must be viewed within a suppositional theory based on what philosophical logicians call the Ramsey test. The Johnson-Laird and Byrne theory is critically examined with respect to its account of basic conditionals, nonbasic conditionals, and counterfactuals.     

Identity and emergency intervention: how social group membership and inclusiveness of group boundaries shape helping behavior

Two experiments exploring the effects of social category membership on real-life helping behavior are reported. In Study 1, intergroup rivalries between soccer fans are used to examine the role of identity in emergency helping. An injured stranger wearing an in-group team shirt is more likely to be helped than when wearing a rival team shirt or an unbranded sports shirt. In Study 2, a more inclusive social categorization is made salient for potential helpers. Helping is extended to those who were previously identified as out-group members but not to those who do not display signs of group membership. Taken together, the studies show the importance of both shared identity between bystander and victim and the inclusiveness of salient identity for increasing the likelihood of emergency intervention.     

Differences in the Timing of Implausibility Detection for Recipient and Instrument Prepositional Phrases

We conducted two word-by-word reading experiments to investigate the timing of implausibility detection for recipient and instrument prepositional phrases (PPs). These PPs differ in thematic role, relative frequency, and possibly in argument status. The results showed a difference in the timing of garden path effects such that the detection of implausible dative recipients (which are clearly arguments) was delayed relative to the detection of implausible instruments (which may not be arguments). They also demonstrated that commitments to syntactic structure were made at the preposition for both dative and instrument PPs. While these results refute delay models of parsing (e.g., Britt, 1994) and syntax-first accounts of PP-attachment (e.g., Frazier, 1978; Frazier & Clifton, 1996), they support constraint-based lexicalist models that enable verb bias and plausibility information to compete (Garnsey, Pearlmutter, Myers, & Lotocky, 1997).     

The Double Life of Double Effect

The U.S. Supreme Court's majorityopinion in Vacco v. Quill assumes thatthe principle of double effect explains thepermissibility of hastening death in thecontext of ordinary palliative care and inextraordinary cases in which painkilling drugshave failed to relieve especially intractablesuffering and terminal sedation has beenadopted as a last resort. The traditionaldoctrine of double effect, understood asproviding a prohibition on instrumental harmingas opposed to incidental harming or harming asa side effect, must be distinguished from otherways in which the claim that a result is notintended might be offered as part of ajustification for it. Although double effectmight appropriately be invoked as a constrainton ordinary palliative care, it is not clearthat it can be coherently extended to justifysuch practices as terminal sedation. A betterapproach would reconsider double effect'straditional prohibition on hastening death as ameans to relieve suffering in the context ofacute palliative care.     

Demographic characteristics,social competence,and behavior problems in children with gender identity disorder: a cross-national,cross-clinic comparative analysis

This study examined demographic characteristics, social competence, and behavior problems in clinic-referred children with gender identity problems in Toronto, Canada (N = 358), and Utrecht, The Netherlands (N = 130). The Toronto sample was, on average, about a year younger than the Utrecht sample at referral, had a higher percentage of boys, had a higher mean IQ, and was less likely to be living with both parents. On the Child Behavior Checklist (CBCL), both groups showed, on average, clinical range scores in both social competence and behavior problems. A CBCL-derived measure of poor peer relations showed that boys in both clinics had worse ratings than did the girls. A multiple regression analysis showed that poor peer relations were the strongest predictor of behavior problems in both samples. This study—the first cross-national, cross-clinic comparative analysis of children with gender identity disorder—found far more similarities than differences in both social competence and behavior problems. The most salient demographic difference was age at referral. Cross-national differences in factors that might influence referral patterns are discussed.     

In the privacy of their own homes: using the internet to assess racial bias

Recent studies suggest that research participants show reduced distortion of their taboo attitudes and behaviors when they take part in Internet-based procedures from outside the laboratory. We explored whether such procedures would reduce distortion in the assessment of racial bias. In Study 1, White participants who completed the study in the laboratory evaluated Black targets more favorably than White targets. This unexpected "outgroup-favoring" pattern occurred in both pencil-and-paper and Internet versions of the study, showing that modality did not produce it; but when participants worked outside the laboratory via the Internet, this pattern disappeared. Study 2 replicated the above findings and further indicated that the reduced distortion in Internet-based studies was due to the removal of the experimenter rather than removing the participants from the laboratory environment. The implications of these findings for the study of controlled processes of prejudice and the nature of Internet-based social communication are discussed.     

Empirical support for the United States Supreme Court's protection of the psychotherapist-patient privilege

This study explored relations between willingness to disclose in 5 psychotherapy scenarios and 2 independent variables (privilege condition and previous therapy experience). Scenarios involved suicidal, gravely disabled, physically abusive, and sexually abusive patients, and a police officer patient who shot a suspect. For each of the 5 scenarios, participants in the privilege condition had significantly higher willingness-to-disclose scores than participants in the non-privilege condition. There were no significant differences between willingness-to-disclose scores of participants with and without therapy experience; neither was there a significant interaction between privilege condition and therapy experience. Privilege condition was more predictive of willingness to disclose than personal characteristics or therapy experience. Results provide empirical support for the U.S. Supreme Court's recognition of the psychotherapist-patient privilege in Jaffee v. Redmond (1996).     

The ‘Medical Body’ As Philosophy's Arena

Medicine, as Byron Good argues, reconstitutes thehuman body of our daily experience as a medical body,unfamiliar outside medicine. This reconstitution can be seen intwo ways: (i) as a salutary reminder of the extent to which thereality even of the human body is constructed; and (ii) as anarena for what Stephen Toulmin distinguishes as theintersection of natural science and history, in which many ofphilosophy's traditional (and traditionally abstract) questionsare given concrete and urgent form.This paper begins by examining a number of dualities between themedical body and the body familiar in daily experience. Toulmin's epistemological analysis of clinical medicine ascombining both universal and existential knowledge is thenconsidered. Their expression, in terms of attention,respectively, to natural science and to personal history, isexplored through the epistemological contrasts between themedical body and the familiar body, noting the traditionalphilosophical questions which they in turn illustrate.
