Electroencephalogram asymmetry during emotionally evocative films and its relation to positive and negative affectivity

The purpose of the present study was to determine if there were differences in hemispheric lateralization during the experience of emotions and if those differences were related to personality style. College-age adult subjects selected for high positive and negative affectivity on Tellegen's Multidimensional Personality Questionnaire (MPQ; Tellegen, 1982) viewed video stimuli selected for their emotionally evocative nature and rated the intensity of the emotions they experienced. The ongoing electroencephalogram (EEG) was recorded while they watched the video clips. Analyses of the EEG data revealed that there were differences in regional activation during the emotional video clips, especially for those stimuli selected to elicit either happy or disgust emotions. These results support the hypothesis that the right hemisphere is specialized for the experience of certain negative affects, whereas the left hemisphere is specialized for the experience of certain positive affects. The findings also indicated some support for the theory that individual differences in personality style are related to differing levels of hemispheric arousal.     

An evaluation of a brief integrity test user orientation program

The purpose of this pilot study was to assess the effectiveness of a brief test user orientation program on increasing service station managers' familiarity with a few key employment testing issues, including their familiarity with theModel Guidelines for Preemployment Integrity Testing Programs. The obtained results reveal that even a brief orientation program was able to significantly increase the managers' stated degree of familiarity with testing issues.     

Family reunions: Visionary encounters with the departed in a modern-day psychomanteum

A poignant feature of many near-death experiences is a visionary encounter with deceased loved ones. Over the centuries, researchers have sought safe ways to replicate near-death and related experiences, hoping to induce the powerful aftereffects of these events. The ancient Greeks contructed psychomanteums, or oracles of the dead, where seekers could consult spirits of the deceased. I describe a modern attempt to recreate the psychomanteum. Like near-death experiences, visionary encounters in this modern psychomanteum are experienced as real and not as hallucinatory, and have profound personal aftereffects. This novel experimental technique may permit the scientific study of phenomena that previously occurred only spontaneously and under uncontrolled circumstances.     

Assessing the acceptability of staff management procedures to direct care and supervisory staff

Direct care and supervisory staff in five residential training programs for persons with mental retardation in North Dakota rated the acceptability of six staff management procedures. Overall, staff rated “Instructions”, “Instructions and Modeling”, “Feedback and Praise”, and “Instructions, Feedback, and Praise”, as significantly more acceptable than “Self-Management” and “Self-Management, Feedback and Praise”. There was a significant group by treatment interaction in which supervisors and direct care staff had significantly different acceptability rating for four of the six procedures. The results were further analyzed by group and implications and future research are discuessed.     

Brief report: An extension of the sequential alternating treatment design using reversals with subjects not available concurrently

This brief report proposes an extension of the traditional Alternating Treatments Design that would be acceptable to use in hospital and residential settings where subjects are often not concurrently available. Concerns about the inability of traditional designs to work in these special situations and the emergence of a “scientist–practitioner split” are discussed. An example of how the Extended Alternating Treatments Design might be used is provided.     

Attenuation of amphetamine-stereotypy by mesostriatal dopamine depletion enhances plasma corticosterone: implications for stereotypy as a coping response

The relationship between amphetamine-induced stereotyped behavior and a neuroendocrine index of arousal, plasma corticosterone (CCS), was investigated. 6-Hydroxydopamine lesions of the caudate-putamen, which produced dopamine depletions of 60%, blocked stereotypy and prolonged the elevation in corticosterone associated with d-amphetamine treatment (5 mg/kg). Similar dopamine depleting lesions of the nucleus accumbens, which attenuated the locomotor, but not the stereotypic, response to AMPH did not have this effect on CCS. This pattern of results supports the hypothesis that stereotypy has a coping function which may serve to alter arousal and further suggests important differences between the nigrostriatal and mesolimbic dopamine projections in modulating the responsiveness of the neuroendocrine system. These results have implications for understanding the function of behavioral stereotypies common to a number of psychopathological conditions, including schizophrenia and childhood autism.     

Setting and response generalization in rational-emotive therapy: A case study

A single case study (n=1) conducted during therapy investigated the relationship between disputing irrational beliefs in vivo and setting and response generalization. Irrational beliefs associated with the subject's anger and depression were disputed at different intervals over a ten week period utilizing a multiple baseline design across four classes in a school setting (setting 1). Depression and anger were rated several times each week. The subject's level of anxiety was also rated in setting 1 but the irrational beliefs associated with it were not disputed. Anger, depression, and anxiety were rated without disputation in a separate work setting (setting 2). Affect ratings significantly decreased across both settings throughout the ten week period. Results indicated that 1) disputing irrational beliefs associated with anger and depression in setting 1 led to reductions in anxiety in this setting (response generalization), 2) anger and depression reductions in setting 2 paralleled setting 1 reductions (setting generalization), and 3) anxiety reductionsWilliam J.

The effects of staff self-management on positive social interactions in a group home setting

The purpose of this study was to evaluate the effectiveness of a participative management (self-management) procedure directed toward increasing the frequency of positive interactions between direct-care staff and group home residents. A component of the self-management procedure, goal setting, was also evaluated. This study took place in two group homes housing a total of 16 male and female adults with moderate to mild mental retardation. Ten direct-care staff served as subjects. It was found that self-management produced an increase in the frequency of positive interactions of staff and residents, but did not produce changes in other behaviors being measured (e.g., negative interactions, self-stimulation, etc.). Goal setting did not result in changes in positive interactions or other target behaviors. Reasons for the different results of self-management versus goal-setting are discussed and further research is suggested.
