Expectancy confirmed again: A computer investigation of expectancy theory

A computerized attempt to replicate Aronson and Carlsmith's test of expectancy theory was conducted. Generally, subjects performed consistent with their expectancy, although the effect of expectancy was strongly attentuated by an overall achievement orientation. The results contradict the hypotheses that experimenter bias, demand characteristics, or differential recall of performance mediate the effects of expectancy upon performance.     

A measure of stereotyping in fear-of-success cues

Prior studies suggest that sex-role stereotypes influence responses to Horner's fear-of-success cue. This study investigates stereotypes about both sex roles and achievement settings. One hundred sixty college males and females wrote stories to different cues, then rated the masculinity-femininity of their characters. Both John and Anne were rated more masculine as medical students than in a neutral setting. Anne was rated more feminine than John in the neutral setting but equally masculine as a medical student. However, Anne's success was not regarded as maladaptive, but competent. Clearly Horner's cue reflects stereotypes; a more ambiguous cue might assess motives more effectively.Portions of this article were presented at the annual meeting of the American Psychological Association in Washington, D.C., 1976.

Pursuit of comfort and pursuit of harmony: culture, relationships, and social support seeking

This research examined whether people from collectivistic cultures are less likely to seek social support than are people from individualistic cultures because they are more cautious about potentially disturbing their social network. Study 1 found that Asian Americans from a more collectivistic culture sought social support less and found support seeking to be less effective than European Americans from a more individualistic culture. Study 2 found that European Americans' willingness to seek support was unaffected by relationship priming, whereas Asian Americans were willing to seek support less when the relationship primed was closer to the self. Study 3 replicated the results of Study 2 and found that the tendency to seek support and expect social support to be helpful as related to concerns about relationships. These findings underscore the importance of culturally divergent relationship patterns in understanding social support transactions.     

Interhemispheric communication involving multiple tasks: A study of children with dyslexia

The study investigated whether inefficient interhemispheric communication is involved in developmental dyslexia using multiple tasks. A finger localization task, rhyming judgment task, primed lexical decision task, and a visual half-field presentation paradigm were used. Nineteen dyslexic children (mean age = 13.1 years) were compared with 26 chronological age-matched normal children. Although the dyslexic group demonstrated significantly slower and less accurate performance in all three tasks, there was no significant group difference in term of interhemispheric communication. However, priming effects demonstrated by the dyslexic group (p < .05) further indicate that their reading problems may stem from the word retrieval process from the long term memory.     

Comparing judgments of stuttering made by students, clinicians, and highly experienced judges

Purpose: The purpose of this study was to compare judgments of stuttering made by students and clinicians with previously available judgments made by highly experienced judges in stuttering. Method: On two occasions, 41 university students and 31 speech-language pathologists judged the presence or absence of stuttering in each of 216 audiovisually recorded 5-s intervals of the speech of adults who stutter. Intrajudge and interjudge agreement were calculated, and comparisons were made to judgments previously made about the same recordings by 10 highly experienced judges of stuttering. Results: Students and clinicians showed similar and relatively high levels of intrajudge and interjudge agreement, but both students and clinicians identified less than half as much stuttering as the highly experienced judges had identified. Conclusions: These results replicate previous findings of high agreement coexisting with low accuracy in students’ judgments of stuttering, extending those findings to show that similar problems are evident in judgments made by practicing clinicians. Implications include the need for explicit stuttering judgment training programs for both students and practicing clinicians.

Educational objectives: After reading this article, the reader will be able to: (1) describe different methods for identifying stuttering and possible problems associated with each method; (2) describe two different methods for reporting interjudge reliability; (3) describe how the identification of stuttering differs for student, clinician, and highly experienced judges.     

Response of female cuttlefish Sepia officinalis (Cephalopoda) to mirrors and conspecifics: evidence for signaling in female cuttlefish

Cuttlefish have a large repertoire of body patterns that are used for camouflage and interspecific signaling. Intraspecific signaling by male cuttlefish has been well documented but studies on signaling by females are lacking. We found that females displayed a newly described body pattern termed Splotch toward their mirror image and female conspecifics, but not to males, prey or inanimate objects. Female cuttlefish may use the Splotch body pattern as an intraspecific signal, possibly to reduce agonistic interactions. The ability of females to produce a consistent body pattern in response to conspecifics and mirrors suggests that they can recognize same-sex conspecifics using visual cues, despite the lack of sexual dimorphism visible to human observers.

Cuttlefish (Sepia officinalis: Cephalopoda) hunting behavior and associative learning

Because most learning studies in cephalopods have been performed on octopods, it remains unclear whether such abilities are specific to octopus, or whether they correlate with having a larger and more centrally organized brain. To investigate associative learning in a different cephalopod, six sexually mature cuttlefish (Sepia officinalis) participated in a counterbalanced, within-subjects, appetitive, classical conditioning procedure. Two plastic spheres (conditioned stimuli, CSs), differing in brightness, were presented sequentially. Presentation of the CS+ was followed 5 s later by a live feeder fish (unconditioned stimulus, US). Cuttlefish began to attack the CS+ with the same type of food-acquisition seizures used to capture the feeder fish. After seven blocks of training (42 presentations of each CS) the difference in seizure probability between CS+ and CS– trials more than doubled; and was found to be significantly higher in late versus early blocks. These results indicate that cuttlefish exhibit autoshaping under some conditions. The possible ecological significance of this type of learning is briefly discussed.Electronic Supplementary Material Supplementary material is available for this article at     

Solidarity across group lines: Secondary transfer effect of intergroup contact,perceived moral distance,and collective action

We tested, in three studies, whether the generalization of contact effects from primary to secondary outgroups—the secondary transfer effect (STE)—occurs for collective action. The results supported a serial mediation model: contact with immigrants by advantaged group members (Italians: Study 1, N = 146, 121 females, M_age = 28.31 years; Study 3, N = 406, 239 females, M_age = 36.35; British people, Study 2, N = 160, 113 females, M_age = 32.31) was associated with lower perceived moral distance toward primary outgroups, which in turn was associated with more positive attitudes and greater collective action intentions toward primary outgroups, and lower perceived moral distance toward secondary outgroups. Lower perceived moral distance toward secondary outgroups and stronger collective action intentions toward the primary outgroup were associated with higher collective action intentions toward secondary outgroups (results were inconsistent for attitudes). We discuss the findings with a focus on how a consideration of perceived moral distance extends current theorizing, and the relevance of generalized prejudice for the STE.
