ASSESSING CHOICE MAKING AMONG CHILDREN WITH MULTIPLE DISABILITIES

Some learners with multiple disabilities display idiosyncratic gestures that are interpreted as a means of making choices. In the present study, we assessed the validity of idiosyncratic choice-making behaviors of 3 children with multiple disabilities. Opportunities for each child to choose between food and drink were provided under two conditions. In one condition, the children were given the food or drink item corresponding to their prior choice. In the other condition, the teacher delivered the item opposite to that chosen. It was reasoned that valid choice-making behaviors would be reflected in a greater tendency to accept the chosen item and refuse the unchosen item. Direct observations revealed all children consistently indicated choices during both conditions. Choices of both the food and drink items were made by all 3 children. A reversal design demonstrated that acts of refusal were more frequent when choices were followed by delivery of the item opposite to that chosen. Similar assessment procedures may be effective in determining the function of idiosyncratic gestures exhibited by persons with multiple disabilities. For children lacking such skills, intervention to teach valid choice-making behaviors may be needed to complement assessment procedures.     

Skinner on cognition

One of the most controversial, if not the most controversial, aspect of behaviorism is its claims (actual and putative) concerning cognition. Part of this controversy is caused by egregious exegetical errors on the part of Skinner's critics. Critics can then easily refute behaviorism by attributing these problematic claims to Skinner. This paper attempts to faithfully describe Skinner's claims regarding cognition. Skinner advances several arguments regarding the role of cognitions in human behavior and in the science of human behavior. We suggest that there are two distinct kinds of claims in this web: 1) claims regarding the proper relation between science and cognitions and 2) claims regarding the status of cognitions as natural events. Due to the multiplicity and interdependence of many of these arguments, it is best to view Skinner's position on cognition as consisting of a web of interdependent claims.     

Changing men's male gender-role attitudes by applying the elaboration likelihood model of attitude change

The traditional male gender role has been associated with a host of psychological and physical problems. In this study, 118 male university students viewed one of two videotaped interventions based on R. E. Petty and J. T. Cacioppo's [(1986) Communication and Persuasion: Central and Peripheral Routes to Attitude Change, New York: Springer-Verlag) elaboration likelihood model of attitude change (ELM) or were in a control group. One intervention was designed to create less traditional male gender-role attitudes, the other to enhance participants' attitudes toward seeking psychological help. Both interventions significantly changed male gender-role attitudes on Brannon Masculinity Scale scores, but not their Gender Role Conflict Scale—I scores, and neither influenced help-seeking attitudes. The overall pattern of scores suggests that men's attitudes about the male role may be less resistant to change than attitudes about one's own gender role or one's fear of femininity.     

Can mental rotation begin before perception finishes?

We conducted six experiments to determine if mental rotation can begin before perception finishes, as allowed by continuous flow models but not discrete stage models of information processing. The results of Experiments 1–3 showed that the effect of shape discriminability on RT was underadditive with the effect of stimulus orientation, suggesting that mental rotation began before shape discrimination had finished and that the two processes overlapped in time. The results of Experiments 4–6 indicated that mental rotation can overlap with color discriminations as well. In both sets of experiments, however, the amount of underadditivity tended to be much less than predicted by models allowing interference-free overlap. This suggests that mental rotation can overlap with perceptual analysis, contrary to fully discrete models, but that little rotation is carried out during this overlap due to interference between simultaneous discrimination and rotation processes.     

The potential role of state-dependent learning in cognitive therapy with spider phobics

Investigated the potential role of state-dependent learning in cognitive therapy with spider phobics. It was hypothesized that one strategy for increasing the effectiveness of cognitive therapy for anxiety would be to induce anxiety in subjects while they were learning the cognitive restructuring principles (i.e., during treatment). Thirty-two undergraduate volunteers were randomly assigned to one of six experimental conditions. Subjects in the five treatment conditions (the sixth was a no-treatment control condition) met for three sessions of cognitive restructuring,in vivo exposure, or a facts lecture (i.e., the placebo group). Results indicated that when working with spider phobics, three sessions of cognitive restructuring,in vivo exposure, or a facts lecture resulted in equal effectiveness immediately following treatment, but are more effective than no-treatment at all.     

Discrimination of picture requests for missing items among young children with developmental disabilities

Two experiments were conducted to assess discrimination of picture requests for missing items among young children with developmental disabilities. In Experiment 1, three children were first taught to request one object when it was missing from a set of two related leisure items. In Experiment 2, two children were taught to request one object belonging to a set of three leisure items. In both studies the requesting response consisted of pointing to a photograph of the missing item. After acquisition of the initial request, discrimination of picture requests was assessed when the second item (Experiment 1) and second or third item (Experiment 2) was missing. Requests for the untrained items emerged in the presence of natural maintaining contingencies and in the absence of instructional prompts for all but the third child in Experiment 1. This child required continued intervention on the initial request. The results suggest that for some children a sequence of intervention and the programming of natural maintaining contingencies may prove effective in promoting the discrimination of picture requests for missing items among young children with developmental disabilities.     

Negative priming depends on ease of selection

Negative priming effects have been offered as evidence that distractor stimuli are identified. We conducted two experiments to determine if such effects occur even when it is easy to discriminate target from distractor stimuli. In Experiment 1, we found the usual negative priming effect when target and distractor positions varied from trial to trial, but not when these positions remained fixed. Experiment 2 extended these results to a situation where the ease of selection varied only in the prime display. These findings argue that irrelevant inputs can be filtered out prior to stimulus identification under certain circumstances and therefore pose problems for strict late selection theories.     

DIRECTIONAL PREFERENCE IN PROBLEM SOLVING

The study investigated the influence of acquired directional scanning habits on two versions (horizontal versus vertical presentation of stimuli) of an inductive reasoning test by contrasting Japanese-speaking and English-speaking (Australian) groups. The developmental trend of that influence was also investigated. Subjects were Grades 1, 5 and 7 students in both groups. The results indicated that the Japanese sample scored higher on the vertical version of the experimental test, while the Australian group scored higher on the horizontal version when timed group testing was administered to the subjects. For the individually administered test without time limit, the most marked effect was with the Australian Grade 5 students who performed better on the horizontal version than on the vertical version.     

Proneness to romantic jealousy and responses to jealousy in others

An experiment was conducted to assess the relationship between dispositional proneness to experience romantic jealousy and perceptions of jealousy in others On the basis of cognitive and motivational constructs, it was hypothesized that (1) Persons high in proneness to jealousy perceive healthy jealous couples as more in love than healthy nonjealous couples, (2) persons high in proneness to jealousy perceive unhealthy jealous couples as less in love than unhealthy nonjealous couples, and (3) persons low in proneness to jealousy perceive healthy jealous couples as less in love than healthy nonjealous couples The latter two hypotheses were supported Results were discussed with regard to the roles of beliefs about jealousy and threats to the perceiver in individuals reactions to jealousy in others
