Gender differences in enrollment in computer camps and classes

Informal reports suggest that computer literacy (computer awareness and programming skills) is sought more often by boys than girls. In order to gather more systematic data on this possibility, questionnaires were sent in the summer of 1982 to directors of summer camps and classes that offered training in programming for microcomputers. Twenty-three directors of summer programs, serving a total of 5,533 students, provided data on enrollment, type of sponsorship of programs (private, public schools, universities), level of difficulty of programming classes, cost, and residential versus day use. Three times as many boys as girls were enrolled in the total sample. The ratio of males to females increased with grade, cost of program, and level of difficulty of course offerings. Possible explanations for differences in enrollment are discussed.     

A COMPARISON OF TWO APPROACHES FOR IDENTIFYING REINFORCERS FOR PERSONS WITH SEVERE AND PROFOUND DISABILITIES

The development of effective training programs for persons with profound mental retardation remains one of the greatest challenges for behavior analysts working in the field of developmental disabilities. One significant advancement for this population has been the reinforcer assessment procedure developed by Pace, Ivancic, Edwards, Iwata, and Page (1985), which involves repeatedly presenting a variety of stimuli to the client and then measuring approach behaviors to differentiate preferred from nonpreferred stimuli. One potential limitation of this procedure is that some clients consistently approach most or all of the stimuli on each presentation, making it difficult to differentiate among these stimuli. In this study, we used a concurrent operants paradigm to compare the Pace et al. (1985) procedure with a modified procedure wherein clients were presented with two stimuli simultaneously and were given access only to the first stimulus approached. The results revealed that this forced-choice stimulus preference assessment resulted in greater differentiation among stimuli and better predicted which stimuli would result in higher levels of responding when presented contingently in a concurrent operants paradigm.     

Prediction of facial displays from knowledge of norms of emotional expressiveness

A study was conducted to examine the accuracy of prediction of facial expressiveness from knowledge of the norms of expressiveness in same-sex and mixed-sex social interactions. Men and women subjects were videotaped while they viewed emotionally loaded stimulus slides and rated their responses to them. The edited videotapes were shown to judges who attempted to identify the emotion reported by each viewer for each slide. A separate group of subjects was asked to rate how acceptable or appropriate it is for a man or a woman to express each target emotion under the conditions of the slide-viewing study. The accuracy of emotion identification data correlated highly with acceptability ratings across emotions and sex pairings, although examined more closely, the data show this predictability only for same-sex pairings. Alternative explanations for these results in terms of display rules and the social demands of interactions are discussed.The authors wish to thank Alan Fridlund for helpful comments on a previous version of this paper.     

Spontaneous attention to primed and nonprimed inputs

The literature is ambiguous with respect to whether attention is drawn spontaneously to expected or unexpected items in mixed arrays. Several studies from our own laboratory indicate that even though expected words are more localizable than unexpected words in unmixed four-word arrays, showing a baseline advantage for expected words, unexpected words are sometimes more localizable than their expected companions in mixed arrays, suggesting that unexpected words attract attention (see, e.g., Johnston & Schwarting, 1996). By contrast, Dark, Vochatzer, and VanVoorhis (1996) observed that expected words were more reportable than their unexpected companions in mixed, two-word arrays. However, because the Dark et al. research did not include arrays in which both words were expected, it is not clear whether their findings reflect an attentional effect over and above a baseline advantage of expected words. The present study added some additional controls in order to assess this possibility. The superior reportability of expected words was even greater in mixed arrays than in unmixed arrays, suggesting that expected words in mixed arrays attract attention. Following Johnston and Hawley (1994), the conflicting effects of expectancy on spontaneous attention are taken as further evidence that the mind/brain system is biased simultaneously toward both what it most expects and what it least expects to perceive.     

Mobility Strategies and Career Outcomes: A Longitudinal Study of MBAs

This research examines the impact of work- and non-work-related mobility on salary, promotions, job satisfaction, and organizational commitment among 671 male and female managers over a 7-year period. Results indicated that those with frequent lateral moves had significant gain in salary increases compared to those who did not move. In addition, frequent lateral moves had a negative impact on work-related attitudes, specifically overall job satisfaction and organizational commitment. Implications of these findings for career strategies and future research are discussed.     

Attributions of success and failure for actors and observers

Causal attributions of a person actually experiencing a success or failure (the actor) and someone who read about the situation (the observer) were compared. Results supported Jones and Nisbett (1971). Actors were relatively more likely to perceive their outcomes as caused by external factors (task difficulty), while observers attributed these outcomes more to internal factors (effort). Attributions for both actors and observers were also strongly affected by whether the outcome was a success or failure. Hypotheses concerning sex differences in attributions were not supported.     

The role of awareness in human conditioning

The cognitive view of human classical conditioning is that Ss are active in thinking about the pattern of stimulus events which occurs, the demands of the situation, and the kind of responses which they give. A question crucially central to conditioning theory is whether these thoughts and expectations determine conditional responding. This paper reports on two conditioning and personality experiments, employing the standard procedure of a single cue CS-UCS schedule and masking task, which assess awareness of stimulus contingencies and demand characteristics by means of a postexperimental questionnaire. Results were quite clear in showing no significant relationship between measures of awareness and eyelid conditioning.     

Developmental trends in cue utilization for attributional judgements

Fourth through twelfth graders of both sexes were tested for developmental trends in making causal attributions for success and failure and in using past history, social comparison, and importance information in making their attributional judgements. Results suggested that basic information processing rules had already developed by the fourth grade but that children continue to develop and become more consistent in applying these rules. Sex differences indicated that girls were more defensive generally in not taking responsibility for their outcomes by attributing them externally.
