Testing for spontaneous use of requests after sign language training with two severely handicapped adults

A variety of procedures have been used to promote spontaneous requesting in persons with developmental disabilities. However, effective use of such procedures depends in part on identifying the stimuli that gained control of requests during intervention. In the present study, two adults with severe disabilities were taught to request a preferred food item with a modified gesture for “eat.” After learning to respond when the trainer held up an item, an assessment of stimulus control was conducted to determine if requests would occur spontaneously, that is, without the trainer having to offer the item. One learner displayed a number of spontaneous requests during the assessment. Natural maintaining contingencies were then introduced to maintain his spontaneous requests. The other learner made no spontaneous requests during the initial assessment, but subsequent tests revealed that he sometimes requested as the trainer was about to display the item. It thus appeared that both learners were responding at an earlier point in the trial sequence. The results suggest that an assessment of stimulus control may be helpful when selecting strategies to promote spontaneous requesting.     

Attitudes, Intentions, and Behavior: A Study of Women's Participation in Collective Action

The present study tests the theories of reasoned action and planned behavior in the context of women's participation in collective action. Participants were 387 women who completed two questionnaires with an interval of 1 year. In the first questionnaire, participants were asked to provide measures of attitudinal, normative, and control factors, as well as measures of intention to participate in 4 group-related activities over the coming year. One year later in the second questionnaire, the same women provided measures of the degree to which they had actually participated in these behaviors during the course of the year. Findings showed strong relationships between attitudinal factors and intentions, and between intentions and behavior. The addition of perceived behavioral control, as specified by the theory of planned behavior, made little difference in regression analyses. Further analyses focused on the mediating role of identification as an activist. This revealed that attitudinal considerations were only important in the prediction of intention for those individuals with a weaker sense of themselves as activists. It is suggested that expectancy-value calculations may be less important in predicting the intentions of strongly committed individuals to engage in group-relevant acts.     

Testing alternative explanations for mortality salience effects: Terror management,value accessibility,or worrisome thoughts?

Previous research has shown that reminding subjects of their mortality encourages negative reactions to others whose behaviour or attitudes deviate from the cultural worldview (e.g. Greenberg, Pyszczynski, Solomon, Rosenblatt, Veeder, Kirkland and Lyon 1990; Greenberg, Simon, Pyszczynski, Solomon and Chatel 1992; Rosenblatt, Greenberg, Solomon, Pyszczynski and Lyon 1989). According to terror management theory, these findings result from a heightened need for faith in the cultural worldview that is activated by reminders of one's mortality. Study I assessed the plausibility of an alternative explanation which posits that mortality salience simply primes individuals' values. Whereas mortality salience led to harsher bond recommendations for a prostitute, a procedure that directly focused subjects on their values did not. Studies 2 and 3 assessed the possibility that reminding subjects of any worrisome future concern would produce the same effect as a reminder of mortality. In both studies, mortality salience led to negative reactions to a deviant and had no effect on self-reported affect, whereas other worrisome thoughts had no effect on reactions to a deviant but did create negative affect. Thus, consistent with terror management theory, mortality salience effects seem to result exclusively from thoughts of death.     

Significant events in a psychodynamic psychotherapy group for eating disorders

This qualitative pilot study was designed to identify and explain significant events for patients participating in a psychodynamic psychotherapy group for eating disorders. Specifically, seven members of a mixed (i.e., anorectic, bulimic, obese) eating disorders group recorded what they perceived as the three most significant events in group meetings for 14 weeks. In addition, group members were instructed to record why each event was significant. Manifest and latent content analyses of the data revealed that members found feedback and observing others the two most common types of significant events, and emotional experience, insight, and relationship the reasons these events had such impact. The implications of these results for working with the eating-disordered patient in group, as well as their implication for general group theory and practice, are discussed.An earlier vesion of this paper was presented at the 1991 meeting of the American Group Psychotherapy Association, New York. This paper was funded, in part, by a California State Faculty Support Grant and a Santa Barbara Cottage Hospital Research Grant awarded to the first author. The authors would like to thank Sean T.

Sleep apnea syndrome: Symptomatology,associated features,and neurocognitive correlates

This article reviews the essential features, types, prevalence, pathophysiology, and neuropsychological correlates associated with the sleep apnea syndrome. Persons who experience the intermittent hypoxia and fragmented sleep characteristic of the sleep apnea syndrome tend to exhibit moderate symptoms of diffuse cognitive dysfunction as well as multiple emotional and psychosocial sequela. It is concluded that more research is required in order to elucidate the relationship between the hypoxic parameters and neurocognitive deficits seen in the sleep apnea syndrome, and that neuropsychological assessment might represent a means whereby the effectiveness of various treatments for sleep apnea may be evaluated.     

Redundancy gains and coactivation with two different targets: The problem of target preferences and the effects of display frequency

When a visual display contains two targets, both of which require the same response, reaction times (RTs) are faster than when only one target appears. This effect has previously been obtained regardless of whether the redundant targets are the same or different in shape, and in at least one set of two-target experiments, the redundancy gains have been larger for different targets (Grice & Reed, 1992). Experiments with two different targets have also revealed violations of the race-model inequality, suggesting that redundant targets coactivate the response (Miller, 1982). The present paper reexamines both of these findings, because both appear to be inconsistent with the interactive race model (Mordkoff & Yantis, 1991). Experiment 1 shows that the race-model inequality is not violated when the experimental design is free of biased contingencies; Experiment 1 also provides evidence that target preferences may artifactually produce the RT advantage fordifferent- oversame-target trials. Experiment 2, however, shows that the race-model inequality is violated when the frequencies of single- and redundant-target displays are equated (without introducing any biased contingencies), implying that the interactive race model cannot account for the results of experiments involving more than one type of target. Alternative loci for coactivation are briefly discussed.     

'When i grow up i want to be …': A longitudinal study of the development of career preferences

The career preferences of a cohort of 1,773 pupils in ten co-educational comprehensive schools were studied at three points between the ages of 11 and 17. At all three ages, there were enormous differences between the sexes in their job plans, although girls and boys gave similar responses to questions about the characteristics of their ideal job. There were also significant differences between children of different social class and academic ability, and some indications of differences between ethnic groups. Individual children showed little consistency in the occupations they named, although some jobs, notably hairdressing and teaching, were chosen at an earlier age than others. One of the strongest predictors of the occupational aspirations of 17 year-olds was their perception of what their parents wanted for them when they were 14. Boys' aspirations seemed to be based on their individual abilities and achievements, whereas girls' aspirations were more strongly related to ascribed factors such as social class.
