Adjustment to War Captivity: The Role of Sociodemographic Background,Trauma Severity,and Immediate Responses,in the Long-Term Mental Health of Israeli Ex-Pows

This study assessed the role of sociodemographic features, pre-captivity combat exposure, captivity severity, emotional responses and coping during captivity, and social support at homecoming, to the short- and long-term mental health of 164 Israeli POWs of the 1973 Yom Kippur War. The major contributors to the POWs' mental health were psychological responses during captivity, followed first by their education and ethnic status, and then by severity of captivity. Both traumatic stress of captivity and the results of the study were discussed in the light of Conservation of Resources (COR) theory.     

Basic Personal Values and the Meaning of Left‐Right Political Orientations in 20 Countries

This study used basic personal values to elucidate the motivational meanings of “left” and “right” political orientations in 20 representative national samples from the European Social Survey (2002–2003). It also compared the importance of personal values and sociodemographic variables as determinants of political orientation. Hypotheses drew on the different histories, prevailing culture, and socioeconomic level of three sets of countries—liberal, traditional, and postcommunist. As hypothesized, universalism and benevolence values explained a left orientation in both liberal and traditional countries and conformity and tradition values explained a right orientation; values had little explanatory power in postcommunist countries. Values predicted political orientation more strongly than sociodemographic variables in liberal countries, more weakly in postcommunist countries, and about equally in traditional countries.     

Are obsessive-compulsive tendencies related to reliance on external proxies for internal states? Evidence from biofeedback-aided relaxation studies

This article presents two studies that examine the hypothesis that obsessive-compulsive (OC) tendencies are associated with a general deficiency in subjective conviction, which leads to seeking and reliance on external proxies to compensate for that deficiency. We examined this hypothesis using a biofeedback-aided relaxation procedure. In Study 1 low OC participants performed better on a relaxation task than high OC participants. More importantly, viewing the biofeedback monitor (an external proxy for the internal state of relaxation) had a different effect on the two groups: Whereas high OC participants performed better, low OC participants did not. In addition, when given the opportunity, high OC participants requested the biofeedback monitor more than did the low OC participants. In Study 2 high OC participants were more affected by false biofeedback when judging their level of relaxation compared to low OC participants. Real relaxation level differences between the two false biofeedback phases among the two groups were not found. These results provide preliminary support for the hypothesis that obsessive-compulsive disorder is associated with deficient subjective conviction in internal states and increased reliance on external proxies. Implications for the understanding of OCD-related rules and rituals as well as for cognitive therapy for OCD are discussed.     

Bridging in social networks: Who are the people in structural holes and why are they there?

The current paper examines the psychological characteristics of people who link tightly connected cliques to each other with friendship ties. Based on the work of sociologist Georg Simmel, I argue that these people are characterized by two separate motivations, which I call entrepreneurial and relationship-building motivations. Using a complete network from a heterogeneous class of Jewish-, Arab-, and Druze-Israelis, I provide the first empirical evidence of their existence. Gould and Fernandez's brokerage roles were calculated for each participant, and triad proportions from each brokerage type were correlated with well-established psychological questionnaires. Results indicate the existence of two psychologically distinct network orientations, easily interpretable in terms of Simmel's analysis of processes in triads.     

Movement and illumination factors in adaptation to prismatic viewing

While wearing laterally displacing prisms, Ss were required to align a spot of light to the phenomenal straightahead. These measurements were obtained at the beginning and at the end of an exposure to prismatic displacement. In addition, Ss either actively controlled movement of the spot of light, or movement was manipulated by E under the direction of the S. Aftereffects were determined by having S position the spot of light with normal vision at the beginning of the experiment and after each measurement obtained under prism viewing. Ss in the darkened room condition who were required to align the spot of light actively showed a significant aftereffect in the direction of prismatic displacement both at the beginning and at the end of the exposure period. No difference in the degree of adaptation was found between those measurements at the beginning and at the end of the exposure period. No significant aftereffects were found when the room was illuminated during prism exposure or when E controlled movement of the light source.     

An analysis of aftereffects in the measurement of the correction effect

Ss, under prismatic viewing, aligned a spot of light to the apparent straightahead first in the dark and then under illumination. Ss made these judgments either by controlling the spot themselves or by directing E in moving it. For both types of alignment procedures, judgments were significantly more veridical in the illuminated room (correction effect). Aftereffects, measured after both the spot alignment in the dark and in the light, were found to be significant only when S moved the stimulus. These results contradict the argument that the egocentric localization processes involved in the production of the correction effect itself are the basis of the aftereffects obtained.     

Response requirements and the contrast effect in loudness judgments

Ss responded to a series of soft tones via category judgments, reaction time responses, or simple nonquantitative discrimination judgments. An evaluation was then made of the contrast effects obtained in the category judgments of these same soft tones when subsequently presented along with a series of loud tones. A control group was also used which did not receive the initial trials with the soft tones. The results indicated: (1) equivalent contrast effects for all four groups for the soft tones and (2) significantly greater judgments of the loud tones in the group that had used category judgments on the initial trials with soft tones. These results, alonR with a trend analysis, were used to argue for a joint semantic shift and equalization of category usage process underlying the contrast effect when Ss are required to denote the stimuli initially by means of category judgments.
