Drug effects in squirrel monkeys trained on a multiple schedule with a punishment contingency

The behavior of four monkeys trained on a multiple schedule was differentially sensitive to selected pharmacological agents. The three components of the multiple schedule were: (1) a variable-interval schedule in which responses were reinforced on the average of once per minute; (2) a concurrent schedule in which every tenth response was reinforced and every fifteenth response, on the average, was shocked; and, (3) a neutral stimulus in the presence of which responses were neither reinforced nor shocked. Pentobarbital, chlordiazepoxide, and meprobamate increased responding during each of the components. Scopolamine and d-amphetamine decreased variable-interval performance, had minimal effects on performance during the concurrent-schedule component, and increased responding in the presence of the neutral stimulus. Chlorpromazine decreased variable-interval responding and had slight effects on the responding during the other two components.     

Development of knowledge bases and the reliability of a decision support system for behavioral treatment consultation for persons with mental retardation: The Mental Retardation-Expert

The development of expert and decision support systems requires the collection, organization, codification, and storage of a body of specialized knowledge. The development, using reconstructive methods, of two such knowledge bases, the first containing the current scientific literature and the second containing an expert’s knowledge, is described for an automated decision support system, the Mental Retardation-Expert. This system provides practitioners with assistance in the treatment of aggressive, self-injurious, and destructive behaviors displayed by individuals with mental retardation or developmental disabilities. The average interobserver reliability of the expert knowledge base ranged from 92.5% to 95.0% when calculated across four clinicians’ assessments of 31 abstracted cases.     

Ignorance is not a victimless crime: The case of the caring teacher,part 2

Confusion about the mandated reporting of child abuse was discovered in a case study to be widespread, including at the state level. Such extensive confusion serves to keep citizens from both seeing the depth of suffering to which children are subjected and responding appropriately to their suffering; and it serves to keep society dissociated from the impact violence has on us.     

Sexual equality,male superiority,and Korean women in politics: Changing gender relations in a “patriarchal democracy”

As a newly industrialized country Korean society may be characterized as a patriarchal democracy, where the Western democratic principle of sexual equality and the traditional Confucian ideology of male superiority contradict each other and complicate the behavioral rules for gender relations. This paper explores the processes of social change in gender relations by examining organizational patterns of social actions of individuals in male-female interactions in South Korea, with a focus on the experiences of women in politics. The analysis suggests the emerging pattern of gender relations in Korean society is a compartmentalized gender schema that is fluid and situationally defined by the individual's nunch'i (tact or savoir-faire).The research on which this paper is based was funded by grants from the National Science Foundation and the East-West Center. I am grateful to the two institutions. Special thanks are also due to Jerry Boucher, Jon McGee, and an anonymous reviewer for their helpful comments on early versions of this paper.     

Gender and Self-Reported Sexual Arousal in Response to Sexual Stimuli: A Meta-Analytic Review

Social constructionist theories and sociobiological perspectives have led to increased interest in gender differences in sexual behavior. This study involved a meta-analysis of gender differences in sexual arousal in response to sexual stimuli. Forty-six studies in which participants were presented with a sexual stimulus depicting males and females and in which participants responded using a self-report measure of arousal were compiled, and 62 independent effect sizes were aggregated. An overall effect size of d = .31 showed a small to moderate-sized gender difference in sexual arousal with men reporting more arousal than women across all studies. There was significant variation in the effect sizes, though, which was only partially explained by variables coded from the studies. It was found that the gender difference was slightly larger for studies using pornographic vs. erotic stimuli, was larger for studies where participants were tested in a private setting or small group compared to a large group, and was much larger for college age participants compared to those who were older than college age. Generally, the pattern of results provided more support for predictions from social influence theories compared to sociobiological theory.     

Ability to generate mental images in students of art

To evaluate the ability to generate mental images and its relations to artistic training, 44 undergraduates were presented with a list of selected fragments from 40 characters in the Roman alphabet. Subjects provided those letters suggested by the fragments for as many items as possible within a 90-second interval. It was hypothesized that students who had received college training in studio art would be able to produce a greater number of candidate images than students not trained in art, resulting in more correct answers and higher scores. Results confirmed the hypothesis. Trained subjects completed significantly more of the letters on the image-generation task than did those not trained in art (p=.0001). This suggests that superior ability to generate images is associated with artistic training. Further, these results imply that, to the degree to which artistic training reflects ability, image generation may also be related to artistic ability.     

Anxious attachment and psychological distress in cardiac rehabilitation patients

This study investigated the relevance of anxious attachment to the differentiation of psychologically distressed and non-psychologically distressed cardiac patients. Attachment is a biologically based behavioral system in which proximity to a special other is sought or maintained to achieve a sense of safety and security. Anxious attachment, as the name denotes, fails to achieve the function of attachment in the sense of individuals having little or no confidence in the availability of their attachment figures. Empirically, three scales (feared loss of the attachment figure, proximity seeking and separation protest) capture the features of anxious attachment as elaborated by Bowlby. These scales were administered to 178 cardiac rehabilitation patients drawn from the cardiac rehabilitation program of the Calgary General Hospital. The results indicate that feared loss and proximity seeking differentiated psychologically distressed from non-psychologically distressed patients. The implications of this finding for the understanding of psychologically distressed cardiac patients are discussed.
