As an extension of previous studies (Urbanczyk, Angel, & Kennelly, 1988) examining the effects of unimanual finger tapping on lateralized cognitive tasks, lateral body orienting was added to an established dual task paradigm to generate differential hemispheric activation and shifts of attention. One hundred twenty university students retained sequences of digits or spatial locations for 20 seconds either alone or during finger tapping. By turning both head and eyes left or right, the hemisphere congruent with the sequences (LH for digits, RH for locations) or incongruent (vice versa) was activated. Activation had little effect on retention means but greatly affected resource composition supporting task performance. Congruent orientation produced significantly higher positive correlations between digit and location tasks than incongruent orientation. Females showed higher sequence retention correlations than males across both orienting groups. For females, congruent activation enhanced tapping rates and retention-tapping correlations. For males, activation affected neither of these. Discussed in light of neuroanatomical research, these results suggest that congruent attentional orienting may integrate regions of the less activated hemisphere into networks of the more activated hemisphere. This unification may occur more readily across the female corpus callosum, producing a greater dependence upon a general attentional resource than for males, who appear to depend more upon hemispheric resources.
This study investigates the status of biofeedback treatment and locus of control (LOC) affiliation on the reduction of tension headache. Three LOC groups designated as internals, powerful-other externals and chance externals (using Wallston and Wallston's, 1978, Multidimensional Health Locus of Control Scale) were administered an eight week electromyogram (EMG) frontalis muscle biofeedback training program using an Autogen 1700 biofeedback unit. Subjects were 12 female and four male undergraduate students who had a history of tension headache. Results indicated no significant difference in frontalis muscle tension between the beginning and end of sessions in either a biofeedback or self-control condition for any of the LOC groups. Further, there was no significant difference among LOC groups in ability to reduce muscle tension in either the training or self-control condition. Finally, neither biofeedback training nor LOC groups were significant predictors of headache reduction. Extreme within-group variability and small sample size affected study findings and these and other implications for future research are discussed.
The non-victimized siblings in incestuous families have often been ignored in research, literature, and treatment. This study explored these siblings' 1) relationship to the victim, 2) attribution of blame, and 3) adjustment. Participants were 30 non-victimized siblings of incest victims, between the ages of 8 and 14. They completed the Sibling Relationship Questionnaire, the Revised Children's Manifest Anxiety Scale, the Self-perception Profile for Children, the Children's Depression Inventory, and a questionnaire developed for this research. Participants' scores were compared with the normative sample scores on several measures. Siblings perceived little warmth and closeness in their relationships to their victimized sisters. Rivalry and conflict were within normal limits. Siblings blamed victims and other family members less than expected, with the greatest amount of blame attributed to perpetrators. Adjustment was impaired. Males demonstrated less athletic competence, less global self-worth, more worry and oversensitivity than normative samples. Females showed a tendency toward less global self-worth and heightened general anxiety. Siblings' overall level of emotional distress was higher than most of the normative samples.
