Expectations for Traditional Family Roles: Palestinian Adolescents in the West Bank and Gaza

This study explored the family role expectationsof 14- and 15-year-old Palestinian young men and womenliving in the West Bank and the Gaza Strip. It wasanticipated that modernization, along with the youth's involvement in the intifada, thepopular uprising against Israeli occupation, hadfostered more liberal family role expectations among theyouth. The data were collected via questionnaire in1994-1995 from all of the ninth grade students attendingUnited Nations Relief and Works Agency (UNRWA) schoolsin the West Bank. The students completed the Arabicquestionnaire at school and took home questionnaires for their mothers and their fathers. In Gaza,samples of the ninth grade students attending UNRWAschools and of those attending schools operated by thePalestinian Ministry of Education were selected. The students' response rates were over 90%,while mothers' and fathers' exceeded 80%. Overall, datawere collected from 7,000 Palestinian families. Theresults revealed that, contrary to our expectation, Palestinian youth desire and anticipate havingtraditional families very similar to those of theirparents. Interestingly, intifada participation was notassociated with a decrease in support for traditional family roles. There were significantdifferences between the boys' and girls' perceptions offuture gender roles in Palestinian society. The youngwomen expressed more liberal attitudes towards women's roles and participation in society, while atthe same time supporting traditional familyroles.     

Randomized controlled trial of yogic meditation techniques for patients with obsessive-compulsive disorder

The objective of this study was to compare efficacy of two meditation protocols for treating patients with obsessive-compulsive disorder (OCD). Patients were randomized to two groups-matched for sex, age, and medication status-and blinded to the comparison protocol. They were told the trial would last for 12 months, unless one protocol proved to be more efficacious. If so, groups would merge, and the group that received the less efficacious treatment would also be afforded 12 months of the more effective one. The study was conducted at Children's Hospital, San Diego, Calif. Patients were selected according to Diagnostic and Statistical Manual of Mental Disorders, Third Edition-Revised (DSM-III-R) criteria and recruited by advertisements and referral. At baseline, Group 1 included 11 adults and 1 adolescent, and Group 2 included 10 adults. Group 1 employed a kundalini yoga meditation protocol and Group 2 employed the Relaxation Response plus Mindfulness Meditation technique. Baseline and 3-month interval testing was conducted using the Yale-Brown Obsessive Compulsive Scale (Y-BOCS), Symptoms Checklist-90-Revised Obsessive Compulsive (SCL-90-R OC) and Global Severity Index (SCL-90-R GSI) scales, Profile of Moods scale (POMS), Perceived Stress Scale (PSS), and Purpose in Life (PIL) test. Seven adults in each group completed 3 months of therapy. At 3 months, Group 1 demonstrated greater improvements (Student's independent groups t-test) on the Y-BOCS, SCL-90-R OC and GSI scales, and POMS, and greater but nonsignificant improvements on the PSS and PIL test. An intent-to-treat analysis (Y-BOCS) for the baseline and 3-month tests showed that only Group 1 improved. Within-group statistics (Student's paired t-tests) showed that Group 1 significantly improved on all six scales, but Group 2 had no improvements. Groups were merged for an additional year using Group 1 techniques. At 15 months, the final group (N=11) improved 71%, 62%, 66%, 74%, 39%, and 23%, respectively, on the Y-BOCS, SCL-90-R OC, SCL-90-R GSI, POMS, PSS, and PIL; P<0.003 (analysis of variance). This study demonstrates that kundalini yoga techniques are effective in the treatment of OCD.     

Is the acquiescent response style problem not so mythical after all? Some results from a successful balanced F scale

It is shown that Rorer's exoneration of the F scale from acquiescent response style contamination is dependent on the finding-that various acquiescence measures fail to intercorrelate. When acquiescence is measured as the total score on adequate balanced scales scored without reversals, significant internal reliability is found. It is found, in fact, even with scales that are not particularly ambiguous. It is concluded that some scales are not responded to meaningfully by some people and if these people are not to be confounded with real high scores, balancing against acquiescence is still needed.     

Motion aftereffect with subjective contours

Stationary lines appear to move from left to right following exposure to lines moving from right to left. This aftereffect, which normally is generated by exposure to moving edges that are defined in terms of local luminance discontinuity, can also be induced by adaptation to displays containing subjective contours. In both cases, stereodeficient observers demonstrated reduced interocular transfer of the aftereffect relative to stereonormal observers. Since interocular transfer of the motion aftereffect entails binocular function within the visual system, these results suggest that the perception of subjective contours depends on excitation of neural feature detectors rather than simply on cognitive inference.     

Effects of class-interval size upon certain frequency distributions of interresponse times

Inter-response time distributions with class intervals of 0.05 and 0.04 sec revealed characteristics not observable with class intervals of 0.5 sec or greater. Bimodalities were clearly evident in the inter-response time distributions for two out of three pigeons. These modes seemed to correspond to two discrete response topographies.     

Judgments of similarity and spatial models

Ss judged the similarity between all pairs of stimulus objects under 3 conditions: when the objects were (a) Munsell 5R color patches varying in value and chroma; (b) parallelorams varying in size and tilt; and (c) circles-with-radius varying in diameter and angle of radius. For each set of judgments, the pattern of deviations from the Euclidean model was used to diagnose the most appropriate spatial model. The results confirm previous findings that the Euclidean space is appropriate for judgments of color patches, but that the city block space is appropriate for judgments of geometrie forms which vary on perceptually distinct dimensions.     

The influence of perceptual and semantic categorization on inhibitory processing as measured by the N2–P3 response

In daily activities, humans must attend and respond to a range of important items and inhibit and not respond to unimportant distractions. Our current understanding of these processes is largely based on perceptually simple stimuli. This study investigates the interaction of conceptual-semantic categorization and inhibitory processing using Event Related Potentials (ERPs). Participants completed three Go–NoGo tasks that increased systematically in the degree of conceptual-semantic information necessary to respond correctly (from single items to categories of objects and animals). Findings indicate that the N2 response reflects inhibitory processing but does not change significantly with task difficulty. The P3 NoGo amplitude, on the other hand, is attenuated by task difficulty. Further, the latency of the peak of the P3 NoGo response elicited by the most difficult task is significantly later than are the peaks detected during performance of the other two tasks. Thus, the level of complexity of conceptual-semantic representations influences inhibitory processing in a systematic way. This inhibition paradigm may be a key for investigating inhibitory dysfunction in patient populations.     

Causal perception of action-and-reaction sequences in 8- to 10-month-olds

Four experiments with 202 8- to 10-month-old infants studied their sensitivity to causation-at-a-distance in schematic events seen as goal-directed action and reaction by adults and whether this depends on attributes associated with animate agents. In Experiment 1, a red square moved toward a blue square without making contact; in “reaction” events blue moved away while red was approaching, whereas in “delay” events blue started after red stopped. Infants were habituated to one event and then tested on its reversal. Spatiotemporal features reversed for both events, but causal roles changed only in reversed reactions. Infants dishabituated more to reversed reaction events than to reversed delay events. Squares moved rigidly or in a nonrigid animal-like fashion. Infants discriminated these, but motion pattern did not affect responses to reversal. Infants also discriminated reactions from launching and dishabituated to reversed reactions lacking self-initiated motion. These results suggest that sensitivity to causation-at-a-distance depends on the event structure but not pattern or onset typical of animal motion.
