Generalized and specific expectancies: Sequential mediators of interpersonal behavior1

Two experiments confirmed sequential mediation of social interaction by investigating the effects of generalized expectancies on specific expectancies and the effects of specific expectancies on performance. Both experiments used a simulated tutoring task in which the subject took the role of tutor while a confederate took the role of student. In Experiment 1 subjects combined generalized expectancies about the effectiveness of certain tutoring responses with specific situational information to produce specific expectancies about the results of the tutoring responses under the experimental circumstances. Experiment 2 replicated this finding and showed that specific expectancies of the relative effectiveness of different responses influenced which response was performed more. Results were discussed in terms of cognitive motivation theory and social learning theory.     

Manipulating the word frequency effect in free recall

A recall advantage for common words was not evidenced when subjects generated or rated the list words on the basis of commonness and on a semantic, phonological, or orthographic basis prior to recall. Recall of the same set of words following only structural judgments of the words resulted in the usual recall advantage for common words. Results were not consistent with interpretations based only on the associative strengths of the recalled items. A process based on categorization of the words to be recalled was suggested as an alternative explanation.     

The effects of alcohol and extreme provocation on the use of a highly noxious electric shock

Intoxicated and nonintoxicated subjects were given the opportunity to administer a potentially injurious level of shock to an opponent who behaved in either a provocative or an extremely provocative manner. The provocative opponent attempted to administer high-intensity shocks to the subject. The extremely provocative opponent attempted to administer high-intensity shocks and the potentially injurious level of shock. The intoxicated subjects in the extreme provocation condition evidenced the greatest increase in the use of the potentially injurious shock. It was concluded that aggression is a function of the interaction of alcohol consumption and level of provocation.     

Perceived objectivity and the effects of evaluative reinforcement upon compliance and self-evaluation in blacks

Two experiments were conducted to investigate the effects of positive and negative reinforcements upon black college students. In the first experiment subjects received either positive or negative reinforcement from a black or a white Evaluator. Behavioral change (compliance) was greater in response to negative reinforcement from a black Evaluator than in response to negative reinforcement from a white Evaluator, while there were no divergent effects of Evaluator's Race upon compliance with positive reinforcement. The same pattern obtained in subjects' self-evaluations. The second experiment offered a test of the hypothesis that the objectivity of black Evaluators was perceived as greater than that of white Evaluators, and that a manipulation aimed at equating the Evaluators on objectivity would attenuate the effects of Evaluator's Race upon compliance and self-evaluation in response to negative reinforcement. These hypotheses were generally supported by the results.     

Recognition memory for words and pictures at short and long retention intervals

In two experiments, subjects studied a long series of words and pictures for recognition. Retention intervals varied from several minutes to a few months. The complicated testing procedures in Experiment I required the use of a traditional correction for guessing to obtain estimates of subjects' memory performance. A comparable, but simpler, design in Experiment II permitted the calculation of sensitivity and bias measures. In both studies, pictorial memory was superior to verbal memory at all retention intervals tested, and this advantage was essentially constant over time. In addition, the experiments identified an increasing tendency to call verbal test items "old" over time. Bias scores in Experiment H revealed that subjects adopted a more lenient criterion in responding to words than to pictures, and increased leniency was noted for both item types over time. Explanations of the results are offered in terms of differences in initial encoding and of a loss of discrimination between experimental and extraexperimental materials.     

Development and evaluation of an inventory to assess adult stutterers'' communication attitudes

The purpose of this study was to develop and evaluate a procedure to assess adult stutterers' communication attitudes. To this end, the investigation was divided into two phases. In Phase I, an assessment inventory based on a tripartite attitudinal model was developed and administered to 107 adult stutterers. Reliability and validity of these procedures were examined, and the inventory was refined. In Phase II, reliability and validity of the attitude assessment procedures were reassessed, and the attitudes of 26 stutterers and 56 nonstutterers were examined. Assessment procedures involved a self-report inventory, which obtained ratings of items in 13 situational subscales representing different speaking situations. These situations were rated using four response scales reflecting behavioral, affective, and cognitive aspects of attitude. Situational responding, response scale scores, and response scale interrelationships are examined. Findings are discussed in terms of the potential value of the inventory and future investigations.     

Yes,they can! Efficient physical effort mobilization according to task difficulty in schizophrenia

The current literature has largely highlighted a deficit of effort-based decision-making for reward in schizophrenia. However, not all studies have dissociated effort from reward, while other studies emphasize that difficulty is the main determinant of effort rather than reward. In this study, 33 individuals with schizophrenia and 32 healthy controls were recruited to perform a decision-making isometric force task. According to motivational intensity theory, task difficulty (i.e., required force) but not reward was manipulated from easy to impossible. Accuracy between force exerted and force required, and choice to perform a task or not were our effort measures. Clinical variables including depression, defeatist beliefs, and apathy were assessed. Our results demonstrated that the schizophrenia group chose to perform easy, moderate, and difficult tasks and exerted the necessary effort to succeed similarly to the non-clinical group. No association between effort and clinical variables was found. Our findings provide new understandings related to effort mechanisms in schizophrenia.

     

Escaping the natural attitude about gender

Alex Byrne’s article, “Are Women Adult Human Females?”, asks a question that Byrne treats as nearly rhetorical. Byrne’s answer is, ‘clearly, yes’. Moreover, Byrne claims, woman is a biological category that does not admit of any interpretation as (also) a social category. It is important to respond to Byrne’s argument, but mostly because Byrne’s argument is a paradigmatic instance of a wider phenomenon. The slogan “women are adult human females” is a political slogan championed by anti-trans activists, appearing on billboards, pamphlets, and anti-trans online forums. In this paper, I respond to Byrne’s argument, revealing significant problems with its background assumptions, content, and methodology.
