Foundations of infants' social group evaluations

Previous research has suggested that infants exhibit a preference for familiar over unfamiliar social groups (e.g., preferring individuals from their own language group over individuals from a foreign language group). However, because past studies often employ forced‐choice procedures, it is not clear whether infants' intergroup preferences are driven by positivity toward members of familiar groups, negativity toward members of unfamiliar groups, or both. Across six experiments, we implemented a habituation procedure to independently measure infants' positive and negative evaluations of speakers of familiar and unfamiliar languages. We report that by 1 year of age, infants positively evaluate individuals who speak a familiar language, but do not negatively evaluate individuals who speak an unfamiliar language (Experiments 1 and 2). Several experiments rule out lower‐level explanations (Experiments 3–6). Together these data suggest that children's early social group preferences may be shaped by positive evaluations of familiar group(s), rather than negative evaluations of unfamiliar groups.     

Religious Quest Orientation and Anti‐Gay Sentiment: Nuancing the Relationship Between Religiosity and Negative Attitudes Toward Homosexuality Among Young Muslims and Christians in Flanders

Public opinion research has repeatedly shown that religious people generally report more prejudice against homosexuality. However, previous research exploring the general mechanisms that underpin this relationship mostly relied on Christian samples in North America. Studies outside North America are few in number and limited in the forms of religiosity they address. Of all indicators that have been studied so far, a religious quest orientation was found to be the only one negatively related to anti‐gay sentiments. This leaves open the question whether the mechanisms for different forms of religiosity can also be found outside North America. Against that background this research note assesses how religious quest orientation, self‐rated religiosity, religious behavior, and authoritarianism are related to prejudice against homosexuality among Christian and Muslim youth aged 14–23 in Flanders (N = 2,834). This study is the first that investigates the relationship between religious quest orientation and anti‐gay sentiments among Muslims. For both Christians and Muslims, we found that even taking into account a wide range of social background and religious characteristics, having a religious quest orientation is related to less prejudice toward homosexuality.     

Perceived threat and depression among patients with cancer: the moderating role of health locus of control

Illness perception was found to be a better predictor of psychological outcome among cancer patients than the objective characteristics of illness. The current study explored the association between the perceived threat of illness (a major aspect of illness perception) and depression among cancer patients. We examined the hypothesis that this association will be higher for persons with low External (others) or internal (self) Health Locus of Control (HLC) than for those with high HLC. The study took an exploratory approach regarding the role that different sources of control (external and internal) may assume. Fifty-seven cancer patients completed self-report measures of Perceived Life Threat (PLT), HLC and Depression. The possible moderating role of HLC on the relationship between PLT and Depression was examined. A significant relationship between perceived threat and depression was found only among participants reporting low levels of internal locus of control. The results support the hypothesis that perception of cancer as life threatening is important factor in determining the level of depression among cancer patients. The results also support the differentiation between internal and external HLC and suggest that internal HLC may be more relevant than external HLC in managing perceived threat. Internal locus of control can be interpreted as having a sense of agency and mastery which is important in managing the cognitive perception of the threat of illness. Further research is needed in order to determine the role of external HLC in managing perceived or actual threats.     

A computerized multidimensional measurement of mental workload via handwriting analysis

The goal of this study was to test the effect of mental workload on handwriting behavior and to identify characteristics of low versus high mental workload in handwriting. We hypothesized differences between handwriting under three different load conditions and tried to establish a profile that integrated these indicators. Fifty-six participants wrote three numerical progressions of varying difficulty on a digitizer attached to a computer so that we could evaluate their handwriting behavior. Differences were found in temporal, spatial, and angular velocity handwriting measures, but no significant differences were found for pressure measures. Using data reduction, we identified three clusters of handwriting, two of which differentiated well according to the three mental workload conditions. We concluded that handwriting behavior is affected by mental workload and that each measure provides distinct information, so that they present a comprehensive indicator of mental workload.     

The Effect of Rehabilitation on Positive Interpretations of Illness

Postoperative patients received one of the three, alternative pain-management treatments: patient-controlled analgesia (PCA); perceived PCA (PPCA without actual control) and continuous intravenous infusion of analgesics (CII). Pain reports, morphine consumption and satisfaction of the groups were compared, and influences of individual differences in preferences for control and trait anxiety were tested. The main findings were: (1) PCA patients consumed less morphine and reported more pain and somewhat higher satisfaction; (2) PPCA patients were intermediate between the other two groups in pain reports and morphine consumption and lowest in satisfaction and (3) individual differences did not moderate the effects of PCA. The findings were interpreted as indicating that the main effect of PCA is increased pain tolerance, and that a bio-psycho-social framework is most appropriate to explain these effects.     

Emotional time distortions: The fundamental role of arousal

An emotion-based lengthening effect on the perception of durations of emotional pictures has been assumed to result from an arousal-based mechanism, involving the activation of an internal clock system. The aim of this study was to systematically examine the arousal effect on time perception when different discrete emotions were considered. The participants were asked to verbally estimate the duration of emotional pictures from the International Affective Picture System (IAPS). The pictures varied either in arousal level, i.e., high/low-arousal, for the same discrete emotion (disgust or sadness) or in the depicted emotion, e.g., disgust/fear for pictures matched for arousal (high-arousal). The results systematically revealed a lengthening effect on the perception of the duration of the emotional compared to the neutral pictures and indicated that the magnitude of this effect increased with arousal level. Nevertheless, variations in time perception were observed for one and the same arousal level, with the duration of disgust-inducing pictures (e.g., body mutilation) being judged longer than that of fear-inducing pictures (e.g., snake). These results suggest that arousal is a fundamental mechanism mediating the effect of emotion on time perception. However, the effect cannot be reduced to arousal, since the impact of the content of pictures also plays a critical role.     

Coping style in predicting posttraumatic stress disorder among Israeli students

Abstract

Two possible motives for sensation seeking behavior, escape from self-awareness and compensatory self-regulation, were investigated in two studies. In Study I a questionnaire was developed to identify the putative escape and compensation motives suspected to contribute to sensation seeking behaviors. In Study II the factor structure of this new measure, called the Risk and Excitement Inventory (REI), was cross-validated using confirmatory factor analysis, and construct validity was examined. Together these studies suggest that the REI comprises two reliable factors, compensation and escape from self-awareness. Study II showed that these factors have a reasonable degree of construct validity. Limits of the measure and the model are discussed, and suggestions are offered for future research.
