The influence of gender on occupational aspirations of kindergarten children

By updating and extending previous research on the effect of gender role socialization on occupational choices of children, this research found very sexstereotypical occupational preferences in a sample of 540 kindergarten children. The girls in the study selected occupations that averaged 87% female and the boys selected occupations averaging 84% male. The boys perceived a significantly wider range of vocational options than the girls. In a reversal condition, children were asked to pretend to be of the opposite sex. Most of the children selected occupations with sex ratios favoring their pretended sex; girls were slightly more stereotypic than boys. An unanticipated finding was the extremeness of reactions of the boys to the suggestion that they pretend to be girls. It is argued that current sex-role socialization fails to recognize the realities of the expanding participation of women in the paid labor force.     

Establishing generalized verb-noun instruction-following skills in retarded children

A transfer of stimulus control procedure was used to establish generalized verb-noun instruction-following skills in two severely retarded boys. Each of 12 verbs was trained, in a multiple baseline order, to criterion with each of 12 nouns in the form of verb-noun verbal instructions. Throughout training, reinforced probes were conducted on both trained and untrained verb-noun combinations. As training progressed, both subjects began to respond correctly to untrained verb-noun instructions. Eventually, a verb needed to be trained in combination with only one noun before generalization occurred to the as-yet-untrained 11 verb-noun instructions involving that verb.     

Individualized learning environments: Intra- and interpersonal consequences

This study examines the effects of individual goal structures on the intra- and interpersonal behavior of 120 fourth-grade children. Each group of four children was introduced to one of two individualized learning programs: (a) workbook materials color-coded according to level of difficulty (allowing implicit comparisons among children as to progress), and (b) materials not coded according to difficulty (discouraging comparisons). In both learning programs, children worked individually (at story writing) and were rewarded for the work. Results indicate that boys, but not girls, who were rewarded equally for doing good work in an individualized setting but who start and end at a lower step than other more frequently took away a toy from those peers with whom they compared themselves than did boys who were rewarded equally for good work and where there were no comparisons. Boys as a group, regardles of condition, gave more prize tickets to themselves than to others and gave more prize tickets to themselves than girls gave either to themselves or others. Both boys and girls appear to adopt the evaluations of their work given by the experimenter and appear to be influenced thereby in later prized-giving to themselves and to others.     

Contingency management in the classroom treatment of long-term elective mutism: A case report

An 11-year-old boy with a six-year history of elective mutism in school was successfully treated with operant reinforcement and contingency management techniques. The plan was carried out by the classroom teacher with a minimum amount of management consultation. Twelve-month follow-up reveals continued maintenance of the verbal interaction indistinguishable from that of other children at school which was set as the criterion for terminating the intervention. The plan was carried out in three stages-relationship-building to develop teacher-pupil interaction into a reinforcing event, audible-response eliciting, and generalization throughout the school building and grounds.     

Sex differences in retention of verbal and spatial characteristics of stimuli

Males and females from Grades 3, 6, and college viewed sets of five or seven letters in a 4 × 4 matrix, and remembered either (a) names of the letters, (b) positions of the letters within the matrix, or (c) both letters and positions. At all grade levels females remembered letters more accurately than positions, while males remembered letters and positions equally well. However, there was also evidence that verbal and spatial information was processed independently by both males and females. Results are discussed in terms of neurological development and sex differences in specific abilities.     

Objective self awareness and self esteem

Based on a theory of objective self awareness three experiments were conducted with undergraduates to test the hypothesis that self-focused attention can alter self esteem levels. In Experiments I and II subjects were exposed either to the sound of their own voices or to the sound of another's voice, and while listening to the tape-recording they filled out a self esteem measure. Consistent with the theory, subjects whose attention was focused upon themselves by means of exposure to their own tape-recorded voices showed lower self esteem than subjects who heard another's voice. The impact of the self awareness manipulation on self esteem was greatest when it was first introduced. In Experiment III the variable of positive-negative feedback on a fictitious personality trait was added to the self-focused attention variable. An interaction resulted such that self-focused attention lowered self esteem given negative feedback, while there was a tendency toward the opposite result given positive feedback.     

Performance of pigeons on delayed simple and conditional discriminations under equivalent training procedures

A pair of experiments investigated the short-term memory of pigeons under delayed simple and conditional discriminations. Trial sequences in both discriminations consisted of a color as the sample stimulus, a memory interval, a line orientation as the test stimulus, and a trial outcome, which was either food reinforcement or blackout. Pecking rates during the test stimulus defined discrimination performance. In the simple discrimination, the sample provided the necessary information regarding the subsequent trial outcome. In the conditional discrimination, the sample and test stimuli conjointly provided this information. In Experiment 1, the two procedures were compared with independent groups of pigeons. In Experiment 2, the comparison was made within subjects. The simple discrimination was acquired more quickly and was performed better with a memory requirement. Introduction of long delays disrupted performance even at shorter delays in both discriminations. Postulation of prospective as well as retrospective mediating processes facilitates the interpretation of these results.     

School-related problems of Mexican-American adolescents

An attempt is made to explain certain selected aspects of the school problems of some Mexican-American adolescents by an analysis of major cultural themes. The data presented suggest that for some Mexican-American adolescents, school has at least the following four meanings: (1) a place where teachers are frequently perceived and treated as authority figures similar to their fathers and, therefore, are targets of rebellion; (2) a place lacking strict external prhibition of encounters with the opposite sex; (3) a public arena of activity where one can bring honor or shame to one's family: and (4) an institution which expects participating individuals to value individual competition and success. Finally, these problems are discussed with respect to problems that Mexican-American female adolescents have in direct expression of anger.     

Conditional reasoning following contradictory evidence: A developmental analysis

Recent evidence suggests that young adults do not correctly understand the logical relationship of the conditional (if p the q) as it applies to hypothesis testing, and most training procedures have not been productive. However, the introduction of contradictory evidence following faulty inferences has led to accurate inferences with conditional statements. Third and seventh grade and college studients (9, 13, and 21 years of age, respectively) were tested to assess developmental differences in improvement following contradiction training and to test whether improved performance transfers to other conditional reasoning tasks. Significant improvement in conditional reasoning was found for the young adult group following the introduction of contradictory evidence, and the positive effect of the treatment transferred across tasks. The third grade students showed no effects from the introduction of the contradiction, but the seventh graders were often confused by the introduction of the contradiction. Seventh grade and college student performances were generally worse than that of the third graders for the positive instances (p · q), but while the contradiction training improved college studients' performance it did not affect the seventh graders. The results are discussed in terms of changes in cognitive structures.     

The teacher-pupil interaction scale: An empirical method for analyzing the interactive effects of teacher and pupil behavior

The Teacher-Pupil Interaction Scale was developed for use by educational consultants to provide teachers with systematic data for analyzing and improving the learning of pupils. The scoring protocol provides for the simultaneous rating of sequential teacher-pupil interactions; a single mark is used to designate both teacher and pupil behavior at each five-second interval. Observations of a target pupil are alternated with other pupils in the classroom to serve as a point of comparison with the target pupil and to provide a general assessment of the classroom climate. Using the sequential record of their verbal and nonverbal interactions with students, teachers can pinpoint conditions serving both as antecedents and consequents of current student behavior. Armed with this information, teachers can effect changes in their instructional program to increase the rate of desired behaviors and eliminate or reduce unwanted responses.     

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.     

Generality of persistence: The role of stimulus and response factors in persistence to punishment

Previous research has shown that intermittent punishment of a response increases its persistence to continuous punishment and that intermittent punishment training in one situation produces persistence to continuous punishment in other situations. Experiment 1 showed that as long as the instrumental response and punishing stimulus were held constant from intermittent to continuous punishment marked differences between these situations had no decremental effect on persistence. Experiment 2 showed that intermittent punishment training of one response resulted in substantial persistence to continuous punishment of a different and apparently incompatible response and that such response change had no more than a marginal effect on persistence. The results were seen as requiring some revision to the traditional conditioning-model interpretation of persistence to punishment.     

Memory and personality: An information processing approach

A consensual model of memory, based on information processing theory is presented. The experimental literature on the interaction between memory and personality is reviewed in terms of this model. It is suggested that past study in this area has failed to utilize the knowledge and techniques of information processing theory, and as a result, has confounded experimental variables. Suggestions for more appropriate research are presented.
