Temporal properties of responding during stimuli that precede response-independent food

Pigeons' keypecks were reinforced with grain on the average of once per minute by schedules that maintained low response rates and by schedules that maintained high response rates. During these schedules, a fixed-duration conditioned stimulus (CS) ranging from 7.5 to 120 sec in duration across conditions terminated with response-independent food. Response rates during the CS were inversely related to CS duration. The rates and the temporal patterns of responding during the shortest CS were similar whether the ongoing schedule maintained high response rates or low response rates. As CS duration increased, the rate and pattern of responding during the CS converged on the rate and pattern of responding maintained by the baseline schedule. These data indicate that changes in responding during stimuli that signal response-independent reinforcement are not homogeneous throughout the CS; that response measures, such as “suppression ratios”, which presume homogeneity may mislead us; and that conditioned suppression and conditioned enhancement may be better talked about in terms of species-specific approach and avoidance than in terms of emotional states.     

Some conditions that affect admissions of attitude change

Previous research has shown yielders to persuasive communications to be negatively evaluated by observers of the persuasion but positively evaluated by the persuaders. Resisters of persuasion, on the other hand, are evaluated positively by observers but negatively by the initiators of the persuasive effort. Two studies were conducted to determine (a) whether individuals are aware of the differing evaluations of yielders and resisters by persuaders and observers and (b) the extent to which targets of influence attempts strategically employ this information to enhance their images in the eyes of others. Experiment 1, a role-playing study, demonstrated that targets of persuasive appeals are cognizant of the pattern of evaluations provided to yielders and resisters by persuaders and observers. Experiment 2 indicated that targets' public reports of attitude change were shaped so as to produce the most positive evaluations from the audience to those reports. The greatest stated influence occurred in the sole presence of the persuasive agent, an intermediate amount of stated change occurred when both persuader and observer were present, and still less occurred in the sole presence of an observer to the influence attempt. The results of anonymous, private measures of change paralleled in pattern those of the publicly admitted change, but were not significant.     

Insights from sadness: A three-step model of the development of altruism as hedonism

Research into the effects of sad mood on prosocial action is reviewed and is used as a vehicle for examining the transformation of altruism from a punishing to a gratifying event. A three-step model of the socialization of altruism as a reinforcer is proposed. The model argues for (a) an initial stage (presocialization) in which altruism occurs rarely among young children because of its punishing function, (b) a second stage (awareness of norms) in which altruism functions as a mechanism for the receipt of positive sanctions, and (c) a final stage (internalization) in which, by adulthood, altruism has acquired a gratifying function through its status as a conditioned reinforcer. Evidence for the functional equivalence of self-gratification and adult altruism is also presented.     

Involvement and response language effects in attitude scaling

An analytic procedure was developed for separating the effects of involvement from the number of response language categories the subject employs in judging a set of sentence stimuli. The procedure treats category usage as an independent variable and an aspect of the subject's response language. Category usage was shown to have significant influence on several attitudinal judgment processes: Informational complexity, mean judgment functions, and a successive intervals analysis testing Thurstone's assumption of the effect of involvement on equal category spacing. The decrement in scale responding typically associated with involvement is shown to depend on category usage operating either singly or in interaction with involvement. Some tentative conclusions about category usage as a response language variable are discussed.     

Outcome predictors in the behavioral treatment of stuttering

The MMPI and subscales of the Stuttering Severity scale were utilized to predict motivation and success in the behavioral treatment of 32 stutterers. Subjects spent a mean of 10 individual sessions in criterion-oriented learning of fluent speech based on speech-muscle relaxation aided by EMG visual biofeedback. Judged motivation and judged success were strongly related to each other and significantly related to MMPI K and Es scores and negatively to F and Sc. Actual success was negatively related to Sc and Pd, completely unrelated to Es, and (if anything) negatively related to K. Results are consistent with previous studies, and show that global judgements of progress were only minimally related to a measure of actual progress.     

Transgression and altruism: A case for hedonism

A model to account for the positive relationship between transgression and altruism was proposed and tested against three alternative formulations—Guilt, Social Justice, and Self-esteem Bolstering. The proposed model, Negative State Relief, asserts that people in a transgression situation behave charitably in order to reduce a general, negative affective state which is induced by exposure to harm-doing and that if the negative state is relieved by some other means, benevolent activity will be rendered unnecessary. All of the experimental subjects were exposed to an act of transgression; half performed the act themselves while half only witnessed it. In one set of experimental conditions (the relief conditions), a positive event—the receipt of either money or approval—was interposed between the harmful act and a fellow-student's request for aid. In another set of experimental conditions (the norelief conditions), no such positive event occurred. It was found, as predicted, that subjects who received a positive event were significantly less helpful than those who did not, but were not different from a control group which had never been exposed to the transgression. It was also found that harm-doers and harm-witnesses were identical in benevolent tendency. The results were interpreted as favoring a hedonistic conception of the nature of altruism. Finally, it was contended that a U-shaped relationship exists between mood state and helping tendency.     

Effects of vicarious reward and punishment on social imitation in chronic psychotics

Despite considerable evidence that modeling procedures provide effective methods for the acquisition and change of behavior, there is very little research on the effects of vicarious reward, and none on the effects of vicarious punishment, on social imitation in chronic psychotics. Two studies (Goldstein et al., 1973: Gutride, Goldstein and Hunter, 1973) demonstrated the superiority of vicarious reward over no-treatment with adult psychotics. However, in neither study was a model no-consequences group included in order to control for the effects of observation per se; therefore, such findings cannot be clearly attributed to vicarious reinforcement (Thelen and Rennie, 1972). The only other study known to bear on this issue revealed no differences in initial learning between a model-rewarded and a model no-consequences group (Olson, 1971).The present study included model no-consequences control groups in an attempt to examine the effects of vicarious reward and punishment on subsequent interview behavior in chronic psychotics. Drawing on the larger body of vicarious learning research (Bandura, 1969). it was hypothesized that such patients demonstrate higher levels of socially appropriate behavior after observation of a model who is (a) rewarded for appropriate behavior or (b) punished for inappropriate responses, and lower levels of appropriate behavior after exposure to a model who is (c) rewarded for inappropriate behavior or (d) punished for appropriate responses, relative to conditions in which the same modeled behaviors elicit no contingent consequences.     

Causal internalization of academic performance as a function of self-esteem and performance satisfaction

In the present investigation, we integrated self-theories (specifically, theories of cognitive consistency and self-esteem) with attribution theory. Our intent was to clarify the effects of different levels of self-esteem and performance satisfaction on causal internalization of academic performance. Subjects were 162 university students who attributed causality for their individual performances on a midterm examination. Attributions to four internal and four external causal sources were analyzed with a 2 × 2 (Self-Concept × Performance Satisfaction) MANOVA and with follow-up univariate F ratios. Most of the findings support the predictions based on self-esteem theory; i.e., satisfaction with performance, rather than consistency of performance with self-esteem, served as the primary influence on internalization of causality, with students internalizing satisfying outcomes more than dissatisfying outcomes. Cognitive-consistency theory and B. Weiner's (1979, Journal of Educational Psychology, 71, 3–25) attribution proposal regarding maintenance of a stable self-concept also received support, as attributions to the internal and stable causal sources of ability and general effort were a function of an interaction of self-esteem and performance satisfaction. Hence, neither self-theory adequately anticipated the effects of self-esteem and performance satisfaction on causal internalization. Rather, a consolidation of theories is needed to explain the results.     

The effect of an overheard ethnic slur on evaluations of the target: How to spread a social disease

An experiment was conducted to assess the effects of an ethnic slur on evaluations of a targeted minority group member by those who overheard the slur. White subjects plus four confederates participated in a study ostensibly concerned with debating skills. Two of the confederates, one of whom was black, were always picked to engage in a debate which the others were to evaluate. The black debator either won or lost the debate. After the debate, one confederate-evaluator criticized the black in a manner that either did or did not involve an ethnic slur; in a control condition, no such comment was made. Based on the notion that ethnic slurs activate negative schemata regarding members of the targeted minority group, it was predicted that when the black debator lost the debate, the ethnic slur would lead to lower evaluations of his skill. This hypothesis was supported. Theoretical and practical implications of the findings were discussed.     

Perceptions of school psychology services from a staff perspective

This investigation examined how staff in an elementary school district perceived their school psychologists and how these perceptions differed across components of service and staff groups. We developed a School Psychological Service Questionnaire and then analyzed responses from regular education teachers, special education teachers, principals, and school psychologists in an urban school district. Although the findings are numerous, most noteworthy are, first, that consumer groups in the district had different perceptions than school psychologists about how school psychologists allocate their time and how this time should be allocated in the future. Second, consumer perceptions of school psychologists' knowledge generally were favorable. Third, in terms of domains appropriate for involvement by school psychologists, a factor analysis of consumer ratings revealed three relatively clear dimensions of recommended service provision — special education activities, interpersonal or school-climate activities, and administrative responsibilities. Fourth, the helpfulness of school psychologists, as perceived by consumers, related positively to frequency of contact. Fifth, differences in perception of school psychological services were evident across staff groups. Finally, comparisons between master's level and doctoral level school psychologists suggested numerous differences in how the staff perceived these service providers.     

Distortion in control attributions for real life events

A pool of life events was prerated as either positive or negative and likely or unlikely to recur. Undergraduate subjects then rated their control over their own life events and the average student's control over his/her life events. As predicted, subjects self-attributed more control over positive than negative events and self-attributed more control than they attributed control to others for positive events. However, self-attributions and attributions to others of control for negative events did not differ. Results thus provided support for self-enhancement but not for self-protection. It was also predicted that control motivation would lead subjects to (a) self-attribute more control for recurrent than nonrecurrent events, (b) self-attribute more control than they attribute to others over all events, and (c) self-attribute more control than they attribute to others for recurrent but not nonrecurrent events. The first and second of these predictions were confirmed, providing support for the operation of control motivation on real life events.     

A quantitative synthesis of literature on work status and subjective well being

Metanalytic techniques were used to synthesize results of studies on the relation of work status (retired, employed part time, employed full time) and subjective well being (SWB). The weighted mean of the work status/SWB relation across all studies was .18. When zero-order associations between work status and SWB were used as dependent variables, significant predictors of that relation were the way in which work status was operationalized, ratings of quality of study, year of publication for studies, and age midrange of samples. Gender was not a significant predictor of the work status/SWB relation.     

The assessment of empathy in early childhood

In much of the literature on empathy in young children, researchers have assessed empathy with the FASTE (Feshbach and Roe Affective Situations Test for Empathy). Consequently, much of the literature on early affective responsiveness and the role of empathy in prosocial development is dependent on the validity of the FASTE. However, examination of the literature on gender differences in young children's empathy has suggested a methodological flaw in picture/story techniques such as the FASTE; children's responses to these instruments appear to vary as a function of the interaction of sex of experimenter with sex of subject. In the present study, we empirically examined the effects of sex of experimenter on children's responses to the FASTE. Eighty preschool children were randomly assigned by sex to four male and four female experimenters and were administered the FASTE. Children scored higher when interviewed by a same-sex experimenter, especially if only the stories that the children comprehended (the happy/sad episodes, not the anger or fear episodes) were examined. The implications of the findings for interpreting the literature on children's empathy (especially gender differences in empathy) are discussed.     

Gender-related aspects of occupational prestige

Prestige of six occupational clusters was studied in relation to gender of the 369 college students who rated the prestige and to gender of imagined jobholders. Subjects rated on a scale of 1–5 the prestige of 30 occupations while envisioning women or envisioning men holding those jobs. Occupations were classified as either female professional, male professional, female nonprofessional, male nonprofessional, neutral professional, or neutral nonprofessional. Classification into these clusters was on the basis of percentage of women and men presently in each occupation and perception of each occupation's sex type, as well as whether college preparation was necessary. Prestige ratings were analyzed by a 2 (rater gender) × 2 (jobholder gender) × 6 (occupational cluster) repeated measures ANOVA. Main effects were obtained for gender (p < .05) and occupational cluster (p < .0001), as well as for the interactions of cluster and rater gender (p < .0001), cluster and jobholder gender (p < .0001), and the three-way interaction of cluster, rater gender, and jobholder gender (p < .01). The significant findings (particularly the interaction between occupational cluster and jobholder gender) seem to indicate that status is not inherent in sex-typed occupations, but is in part a function of the gender of the person imagined to be holding the job, and of the gender of the rater.     

Hypothesis analysis of sameness-difference learning-set by capuchin monkeys

Sameness-difference discriminations were presented to capuchin monkeys and hypothesis analysis was applied to the data. Learners and nonlearners evidenced differences in overall performance and in relative strengths of hypotheses. Learners initially displayed markedly more random than position responding whereas nonlearners evidenced more position than random responding and remained particularly prone to position habits. Stimulus preference and aversion, suppressed by learners by the end of training, reemerged at the onset of two-object discriminations containing previously preferred and aversive stimuli. Hypothesis analysis indicated that when preferred stimuli were positive the correct hypothesis was more evidenced, and stimulus preference or aversion as well as random hypotheses were less evidenced, than when aversive stimuli were positive.     

The effect of training procedures on the overlearning reversal effect in young children

The performance of 80 preschool children on a reversal problem was studied as a function of amount of training and type of training procedure used during acquisition and reversal. In the extinction phase of reversal learning, subjects given a correction procedure during the reversal problem made fewer perseverative errors than subjects given noncorrection. In the reversal midplateau phase of reversal learning, overtraining facilitated reversal learning for subjects receiving noncorrection during the acquistion problem, but not for subjects receiving correction. A shift in training procedure between acquisition and reversal increased the number of subjects who reached criterion immediately after perseveration. Since these results are difficult to explain in terms of traditional learning theories, an alternative response-switching strategy explanation was proposed.
