Conservation acquisition, maintenance, and generalization by mentally retarded children using equality-rule training.

To teach conservation to mildly retarded, preoperational preadolescents (9 to 12 years old), a number-representational system was used to mediate the invariance of quantity as part of "equality-rule" training. Before viewing a perceptually misleading configuration of either two equal quantities or two unequal quantities entailing the dimensions of number or length, participants learned that equality involved the assignment of two identical numbers and inequality the assignment of two different numbers. These numbers were then applied to the actual quantities and became the basis for rule statements that were rehearsed, memorized, and subject-generated each time the quantities were transformed into a new configuration. Following equality training, correct judgments and verbal justifications of conservation were high (M greater than or equal to 85%) during both immediate and delayed post-tests and for near-generalization (number and length) and far-generalization (weight, liquid substance, and solid substance) tasks. In contrast, the post-test levels of comparable participants given learning-set (LS) training, LS plus verbal-rule training (a combination of statements about identity, negation, and compensation), or no training at all were substantially and significantly lower. Equality training is of theoretical and practical interest because of its potential to teach a symbolic representational rule that directly and meaningfully articulates the quantitative properties of objects and counteracts the overreliance on task-specific and faulty perceptual cues inherent in the conservation task.     

Conditional automaticity in subliminal morphosyntactic priming

We used a gender-classification task to test the principles of subliminal morphosyntactic priming. In Experiment 1, masked, subliminal feminine or masculine articles were used as primes. They preceded a visible target noun. Subliminal articles either had a morphosyntactically congruent or incongruent gender with the targets. In a gender-classification task of the target nouns, subliminal articles primed the responses: responses were faster in congruent than incongruent conditions (Experiment 1). In Experiment 2, we tested whether this congruence effect depended on gender relevance. In line with a relevance-dependence, the congruence effect only occurred in a gender-classification task but was absent in another categorical discrimination of the target nouns (Experiment 2). The congruence effect also depended on correct word order. It was diminished when nouns preceded articles (Experiment 3). Finally, the congruence effect was replicated with a larger set of targets but only for masculine targets (Experiment 4). Results are discussed in light of theories of subliminal priming in general and of subliminal syntactic priming in particular.     

Rational Thinking and Stress Management in Health Workers: A Psychoeducational Program

The paper describes the rationale and contents of a graduate-level practicum on stress management. The course objective is consistent with the current call for improved training in psychological issues in medical education. Participants were 39 occupational health practitioners (physicians, industrial hygienists, nurses, and physiotherapists) in the Tel-Aviv University Medical School graduate program in occupational health. Twenty-five students in the same program who did not participate in the practicum were included as comparison subjects. The course was based on a cognitive-behavioral model (Rational-Emotive Behavior Training) developed by Ellis. The one-semester practicum aimed to reduce irrational/dysfunctional thinking patterns which are considered to be causal factors in stress etiology. Irrationality was significantly reduced by the end of the course and perceived psychosocial professional efficacy was increased. The improvements in such personal anti-stress resources may benefit health workers and clients alike. It is recommended to include such courses to the professional training of all health care practitioners.     

Stress management and burnout prevention in female blue-collar workers: Theoretical and practical implications

Occupational stress is a pervasive problem among blue-collar workers, and women employees are especially vulnerable, yet this population is rarely addressed. The study concerns a stress management training program developed for female production workers with little formal education, based on the cognitive approach of Rational-Emotive-Behavioral Training (REBT). Several strategies and teaching aids suitable for such a population are suggested. Twenty-seven women participated in the program. Fourteen of them comprised the waiting-list control group. Burnout, tension, listlessness, cognitive weariness, and work/home conflict were assessed before, at the end, and at 12 months follow-up. At the end of the six-session program, four of the five measures in the experimental group were significantly reduced compared to the control group. At the 12 months follow-up, tension and burnout were still reduced compared to baseline suggesting that REBT can be successfully taught to such participants but booster sessions are required.     

The neural reality of syntactic transformations: evidence from functional magnetic resonance imaging

The functional anatomy of syntactic transformations, a major computational operation invoked in sentence processing, was identified through a functional magnetic resonance imaging investigation. A grammaticality judgment task was used, presented through a novel hidden-blocks design. Subjects listened to transformational and nontransformational sentences in which a host of other complexity generators (number of words, prepositions, embeddings, etc.) were kept constant. A series of analyses revealed that the neural processing of transformations is localizable, evoking a highly lateralized and localized activation in the left inferior frontal gyrus (Broca's region) and bilateral activation in the posterior superior temporal sulcus. The pattern of activation associated with transformational analysis was distinct from the one observed in neighboring regions, and anatomically separable from the effects of verb complexity, which yielded significant activation in the left posterior superior temporal sulcus. Taken together with neuropsychological evidence, these results uncover the neural reality of syntactic transformations.     

The localization over time of exogenous aldosterone and angiotensin II in various organs

Central nervous system effects have been demonstrated for angiotensin II and suggested for aldosterone. In order to determine whether either of these chemicals naturally crosses the blood-brain barrier, radioactive aldosterone and angiotensin II were introduced via intracardiac injections in rats. Samples of blood, liver, kidney, adrenals, cerebral cortex, and hypothalamus were collected at three, 15, and 60 minutes, frozen, dissolved, and counted. Blood levels for aldosterone and angiotensin II remained constant over 60 minutes. Aldosterone accumulated in the liver, kidney, adrenals and hypothalamus three minutes after injection, and levels diminished over time. Angiotensin II levels peaked in the adrenal, kidney, and liver after three minutes, and in the hypothalamus after 15 minutes. Cerebral cortex levels were lower than hypothalamic levels by 30% for aldosterone and 50% for angiotensin II. This suggests that both drugs may enter the central nervous system and selectively accumulate in the hypothalamus.     

A rational-emotive group intervention for preventing and coping with stress among safety officers

A stress management and prevention workshop for nonclinical industrial workers using rational-emotive principles with 18 months followup is reported. Twenty-two senior safety officers participated in an intervention program of five weekly meetings aimed at improving cognitive skills and assertiveness mainly by decreasing irrational thought processes. We hypothesized an increase in assertiveness, and a decrease in irrational beliefs, and emotional and cognitive stress symptoms (manifested in somatic complaints and cognitive weariness). Assertiveness improved and somatic complaints and irrationality decreased in the short term. Eighteen months later, cognitive weariness was also reduced. The other improvements were still evident, but not to the same extent as short-term effects. Although the workshop improved rationality, further practice would be needed in the behavioral aspect of stress prevention to achieve long-term improvements in assertiveness.Talma Kushnir, Ph.D., is a social and medical psychologist at the Occupational Health and Rehabilitation Institute, Raanana, Israel, and teaches psychology and health promotion at the Tel-Aviv University Medical School.Ruth Malkinson, Ph.D., fellow and RET trainer and supervisor of the Institute for RET, and teaches at the School of Social Work and Medical School at Tel-Aviv University, Israel.

Domestic Stress and Well-Being of Employed Women: Interplay Between Demands and Decision Control at Home

Family researchers have suggested that shared decision control is important for coping with stressful demands at home, whereas occupational stress theorists view personal decision control as an essential coping resource. We studied the effects of home demands, personal decision control, and shared decision control at home on burnout and satisfaction with life, using Karasek’s job-demands-control model to gauge home stress and its outcomes. Participants were 133 mothers employed in secretarial and managerial jobs. We hypothesized that shared control would correlate more strongly with burnout and satisfaction with life than would personal control. In multiple regression analyses, demands had independent main effects on both outcomes. Shared control significantly predicted satisfaction with life, but not burnout, and personal control predicted neither. It is suggested that in families (as in teams), shared decision control may be a more potent coping resource than personal control.
