Anticipation of reward omission as a cue for choice behavior

A within-subject partial reinforcement extinction effect was obtained in a conditional discriminative choice task. In choice acquisition, one group had learned a task in which one choice alternative was continuously reinforced (CRF) and the other alternative was partially reinforced (PRF). Most errors in the acquisition phase were the choosing of the CRF lever when the conditional stimulus signaled the PRF lever; in extinction this pattern of choice errors reversed. In extinction, most errors were choosing of the PRF lever when the conditional stimulus signaled the CRF lever. The predictions of frustration theory and sequential theory were compared with the choice data. The results were interpreted as consistent with the anticipatory frustration construct within an associative mediational theory.     

Test anxiety and reaction time for matching decisions

Subjects selected by test-anxiety level were presented pairs of words and asked to make judgments of physical identity, acoustic matching, or taxonomic category membership. Experiment 1 varied type of judgment between subjects; in Experiments 2 and 3, each subject made all three decisions. There was no consistent support for the hypothesis that, relative to low-anxiety subjects, high-anxiety subjects would show a more pronounced decrement in reaction times for semantic decisions than for nonsemantic decisions.     

Determinants of reduction in intended effort as a strategy for coping with anticipated failure

The present study investigated the use of reduction in intended effort as a strategy for protecting self-esteem from the threat of anticipated failure. It was hypothesized that people reduce the amount of effort they intend to exert when they expect a low probability of success on a highly ego-relevant task. Female subjects anticipated taking an easy (high probability of success) or difficult (low probability of success) test that was either high or low in ego relevance. Subjects' levels of intended effort and other task-relevant cognitions were assessed. It was found that subjects in the low-probability condition intended to exert less effort on the highly ego-relevant test than did subjects in the high-probability condition; probability of success had no effect on intended effort level on the low ego-relevance test. Subjects also reported that it was a worse day for a test in the low-probability condition than in the high-probability condition. The relevance of these findings to the egotism explanation of learned helplessness effects and general theories of motivation was discussed.     

The relationship between treatment exposure times and changes in stuttering frequency during contingent stimulation

Four adult stutterers were exposed to 60 consecutive minutes of verbal contigent stimulation. In each session subjects spoke until a stuttering frequency stability criterion was met (baserate) followed by 60 min of exposure to the word wrong presented contingently upon each instance of stuttering. The data were analyzed according to changes in stuttering which occured following 20, 40, and 60 min of treatment exposure. The results revealed that stuttering frequency was reduced for all subjects during all three 20-min segments of the treatment condition. The only significant reductions in stuttering frequency, however, occured within the first 20 min of treatment.     

Individual differences in the ability to focus and divide attention

This research deals with individual differences in the ability to focus and divide attention. Eighty-five subjects performed visual search and auditory detection tasks in three conditions: single channel, focused attention, and divided attention. Reaction time (RT) was fastest in the single channel condition, intermediate in the focused attention condition, and longest in the divided attention condition, and these effects were much stronger in the auditory than the visual task. Correlations among RTs in the three conditions were very high within modality (>.88), and lower between modalities (.5 to .6). The correlational data was well fit by a model that included separate factors for the visual and auditory tasks. Measures from the three attentional conditions within each modality loaded equally on these factors. The data provided no evidence for distinct abilities to divide or focus attention.     

Characteristics of consultants and consultees and success in mental health consultation

Selected attitudinal and value characteristics of high and low successful consultants were considered. Twelve consultants and 15 consultees completed six measures. Consultants were categorized as high or low success consultants based on the coding of consultants' logs. Results indicate high and low success consultants do not differ on the selected characteristics. Also, the results indicate that more successful consultants have consultees who are more authoritarian and dogmatic and are more dissimilar to their consultees in level of dogmatism and reported need for assistance. Future investigations will indicate whether the results can be replicated on a more representative consultee sample.     

A multivariate comparison of the intellectual performance of black and white children matched on four demographic variables

This study investigated the performance of 285 matched pairs of Black and White children from the standardization sample on the 12 subtests and 3 IQ scales of the Wechsler Intelligence Scale for Children—Revised (WISC-R). The children were matched on four demographic variables found in a previous (Reynolds and Gutkin, 1979) study to be significantly related to WISC-R performance: sex, socioeconomic status as determined by the occupation of the head of household, region of residence in the U.S. and urban vs rural residence. Multivariate analysis of variance comparing performance across race on the 15 dependent variables revealed that Whites exceeded Blacks on all tasks except Digit Span—a test of rote memory. Results were also related to the evaluation of the Spearman hypothesis.     

Pressures from work,self, and home in the life stages of married women

Following Lopata's (1966) model of the life cycle of the married woman's role, it was predicted and found that a woman's life stage would be related to her role pressures (work, home, self, and time), conflict, and satisfaction. Age and number of roles were not as strongly related to these variables as was life stage. Work activities and pressures declined through the peak child-rearing stage and then increased for women with older children, while pressures from home generally rose throughout the life cycle. The differential impact of various sources of conflict in different life stages was reported, and forms of organizational career support oriented toward particular life stages were suggested.
