Psychophysiological and cognitive responses to stressful stimuli in subjects practicing progressive relaxation and clinically standardized meditation

Thirty-six volunteer subjects were assigned to one of three conditions: progressive relaxation, clinically standardized meditation, or a waiting list control group asked to relax daily (without specific instruction). Subjects were given paper and pencil tests two times, separated by 5 weeks during which time the two treatment groups received 4 weekly sessions of group training. All subjects were tested in the psychophysiology laboratory at the end of the 5-week period, during which time they were exposed to 5 very loud tones. While relaxing as deeply as possible using the techniques they had learned and anticipating the loud tones, the meditation group exhibited higher heart rates and higher integrated frontalis EMG activity, but they also showed greater cardiac decelerations following each tone, more frontal alpha, and fewer symptoms of cognitive anxiety than the other two groups. The relaxation group reported more sensations of muscular relaxation than the other groups, but also some symptoms of hyperventilation. The results are generally consistent with Davidson and Schwartz's (1976) categorization of meditation as a ‘cognitive’ technique, and suggest that frontal EEG alpha may be a physiological marker for the absence of cognitive anxiety. Physiological findings also support Goleman and Schwartz's (1976) suggestion that meditation prepares people to cope with stress.     

Vocational interests of career and homemaker oriented women

Women who had completed the SVIB-W as freshmen in college were contacted 13 to 21 years later and were classified as career (N = 236) or homemaker (N = 527) oriented on the basis of their actual work experiences. Significant differences between the groups were found on 25 of the 44 occupational scales, one of the three nonoccupational scales, and four of the 19 basic interest scales. The interests of the homemaker oriented women were more similar to the interests of women in business, nonprofessional, and home economics occupations while the interests of the career oriented women were more similar to the interests of women in the verbal-linguistic, verbal scientific, and scientific occupations. The results are discussed in terms of previous research and Holland's Occupational Classification system.     

Teaching chained skills in a non-school setting using a divided half instructional format

This investigation evaluated the use of dyadic instructional arrangements in teaching chained skills to four students with moderate mental retardation. Each instructional dyad consisted of two students. Each of the three cooking skills was divided into two equal parts, and each student in a dyad received direct instruction on one part of the task analysis during each instructional session. During the following session, the two parts were reversed and a student received instruction on the second part. A constant time delay procedure was used to teach the targeted skills in an off-campus setting. A multiple probe design across skills and replicated across students evaluated the effectiveness of the instructional procedure and teaching arrangement. Results indicate that each of the four students learned the three cooking skills. Implications for future research are discussed.     

Reliability of psychophysiological assessment

In order to assess the reliability of psychophysiological recording, 15 subjects were assessed on multiple response measures (forehead EMG and forearm flexor EMG, heart rate, skin resistance level, hand surface temperature and cephalic vasomotor response), under multiple stimulus conditions (baseline, self-control, cognitive and physical Stressors), on multiple occasions (Days 1, 2, 8 and 28). Three forms of reliability coefficients were computed for each response measure: coefficients on absolute scores, coefficients on change scores from baseline to stressful conditions and coefficients on percent change from baseline. Only frontal EMG appeared to have consistently high absolute reliability coefficients, with hand surface temperature having high reliability if sessions are repeated within 1 week. Heart rate was less consistently reliable. Treating the responses as relative measures did not increase their reliability; indeed, hand surface temperature was completely unreliable when examined in this fashion. Implications of this study for behavioral medicine, biofeedback and anxiety-based disorders research, as well as Lang's tripartite response system model of fear and emotion, are discussed.     

A comparison of moral reasoning and moral character in male and female incarcerated felons

Gender differences among incarcerated adult felons along dimensions of moral reasoning and moral character were examined. Previous work was extended by comparing adult male and female felons, and by exploring the relationship between moral reasoning and moral character. Subjects completed the Socio-moral Reflection Questionnaire, which measures moral reasoning. Moral character was assessed by a socialization scale, two empathy measures, and two autonomy questionnaires. Discriminant function analysis revealed that men were higher than women on moral reasoning, lower on socialization, higher on role-taking empathy, lower on emotional empathy, and more internal in locus of control. Moral reasoning was correlated with role-taking empathy and locus of control. Implications for theories of gender differences in moral reasoning and criminality were discussed.     

Predicting reading achievement in the first year of schooling: A comparison of readiness tests and instructional programs

Data from four reading-related tests, including a measure of knowledge about books and print conventions, and two demographic variables, obtained at the end of the first year of schooling, were used to predict a range of students' word and discourse reading achievement at the conclusion of that year. Students were enrolled in a reading program that emphasized either the subskills involved in breaking the reading code or the more holistic gaining of meaning from print. The results indicated that a measure of knowledge about books and print conventions is strongly related to end-of-year reading achievement, but that, over and above the other more traditional measures, it is a significant predictor of only one type of comprehension - that involving the inferential linking of two pieces of information separated in the text. Students in a subskills-emphasis program outperformed those in a meaning-emphasis program on tests of word knowledge but not of comprehension of discourse.     

Controversies in counseling for mitochondrial conditions

A healthy woman sought preconceptional genetic counseling regarding a family history of a mitochondrial myopathy in her brother and retinitis pigmentosa (RP) in her two maternal aunts. Several questions were raised: (1) What is the likelihood of a familial mitochondrial condition? (2) What molecular tests or prenatal screening can we offer? (3) How would these tests help assess the likelihood of a familial mitochondrial condition? A mitochondrial mutation previously identified in the brother consisted of a heteroplasmic 2.9 kb deletion. We detected this deletion in the peripheral blood of the brother by PCR amplification of the deletion breakpoint, but not in his mother, the consultand, nor in one of the two aunts affected with RP. Although the molecular analysis was encouraging to the consultand, a familial mitochondrial disorder could not be eliminated with certainty. The pros and cons of prenatal testing for mitochondrial disorders are discussed in general, and as specifically related to this family.
