Coping, locus of control, social support, and combat-related posttraumatic stress disorder: a prospective study

We examined the relations between coping, locus of control, and social support and combat-related posttraumatic stress disorder (PTSD). The sample consisted of 262 Israeli soldiers who suffered a combat stress reaction episode during the 1982 Lebanon war and were followed 2 and 3 years after their participation in combat. Cross-sectional analyses revealed significant relations between locus of control, coping, and social support and PTSD at the two points of assessment. Changes in PTSD from Time 1 to Time 2 were also associated with changes in coping. We discuss theoretical and methodological implications of the findings.     

The epistemic efficacy of stupidity

I show that it follows from both externalist and internalist theories that stupid people may be in a better position to know than smart ones. This untoward consequence results from taking our epistemic goal to be accepting as many truths as possible and rejecting as many falsehoods as possible, combined with a recognition that the standard for acceptability cannot be set too high, else scepticism will prevail. After showing how causal, reliabilist, and coherentist theories devalue intelligence, I suggest that knowledge, as contemporary theories construe it, is not a particularly valuable cognitive achievement, and that we would do well to reopen epistemology to the study of cognitive excellences of all sorts.I am grateful to Warren Goldfarb for sharing his knowledge of wines with me, and to Kenneth Winkler for sharing his knowledge of birds.     

Intentional and incidental visual memory as a function of cognitive level and color of the stimulus

Performance of two groups of youngsters, educable mentally retarded (CA 15-5; MA 11-4; IQ 74.3) and those of average ability (CA 10-5; MA 11-3; IQ 109.1) was compared for intentional and incidental visual memory as a function of cognitive level and color of the stimulus. Nonretarded subjects performed significantly better than the retarded ones of equal MA. Both groups performed better with a color than black-white card, and both groups did better on the tasks involving intentional rather than incidental memory.     

From front line to home front: a study of secondary traumatization.

While the long-term effects of combat trauma on veterans have been studied extensively, its impact on veterans' wives has yet to be investigated. This study examined the implications of combat-induced psychopathology--wartime combat stress reaction (CSR) and current posttraumatic stress disorder (PTSD)--in a sample of 205 wives of Israeli combat veterans of the 1982 Lebanon war. Results show that both CSR and PTSD were associated with increased psychiatric symptoms in the wives. In addition, current PTSD was particularly found to contribute to impaired social relations among veterans' wives in a broad range of contexts, from inner feelings of loneliness, through impaired marital and family relations, and extending to the wider social network. Implications of these findings for treatment and further research are discussed.     

记忆训练对改善少年、青年和老年人认知功能的作用

本工作采用“位置法”(method of loci)对24例少年、24例青年和22例老年被试进行了记忆训练研究。以毕生发展的观点比较认知训练对改善不同年龄人记忆的作用,进而探讨发展的认知功能储备能量的年龄差异和训练的迁移效应。结果表明认知干预措施可在一定程度上改善老年人的记忆,同时也显示了在发展的储能和对图形的迁移效应方面,老年人明显不如青、少年,而青年与少年则彼此相近。     

Individual gustatory reaction times to various groups of chemicals that provoke basic taste qualities

Reaction times (RTs) to four groups of substances that provoke different taste qualities were measured. Measurements for all substances with the same taste, equalized in perceived intensity and provoking a very strong taste, were made concurrently for each subject. The comparisons were made on the individual level. No significant differences in RTs to substances with the same taste quality were found. When the factor of perceived intensity is kept constant, no effect of the stimulus chemical composition on RTs seems to be present. RTs to stimuli with different tastes differ significantly, the shortest being to salt and the longest to bitter. The difference in RTs for sour and sweet substances is small, and the subjects were not all alike in terms of the order of RTs with respect to these stimuli.     

Emotions and emotional communication in infants

Important advances have recently been made in studying emotions in infants and the nature of emotional communication between infants and adults. Infant emotions and emotional communications are far more organized than previously thought. Infants display a variety of discrete affective expressions that are appropriate to the nature of events and their context. They also appreciate the emotional meaning of the affective displays of caretakers. The emotional expressions of the infant and the caretaker function to allow them to mutually regulate their interactions. Indeed, it appears that a major determinant of children's development is related to the operation of this communication system. Positive development may be associated with the experience of coordinated interactions characterized by frequent reparations of interactive errors and the transformation of negative affect into positive affect, whereas negative development appears to be associated with sustained periods of interactive failure and negative affect.
