A fiery conflict: Attachment orientations and the effects of relational conflict on sexual motivation

This study examined the effects of relational conflict on sexual motivation. Sixty‐one couples were videotaped while discussing either a major relationship problem or their daily routine. Both partners then completed measures of sexual motives and rated their romantic partner's sexual attractiveness. Results showed that conflict discussion inhibited relationship‐based motives and had an adverse effect on women's perceptions of partner's attractiveness, but a beneficial effect on men's perceptions. Conflict discussion also inhibited self‐serving sexual motives such as having sex to obtain relief from stress among people with avoidant partners, suggesting that people are unlikely to turn to avoidant partners for sexual consolation. Implications for understanding the role of the sexual system in regulating reactions to relationship distressful events are discussed.     

The cortical representation of centrally presented words: A magnetic stimulation study

The right and left visual fields each project to the contralateral cerebral hemispheres. The current study aimed to investigate the extent of the functional overlap of the two hemifields along the vertical meridian. We applied repetitive transcranial magnetic stimulation (rTMS) over the left and right occipital cortex to investigate whether the foveal representation of words is bilaterally represented or is split between the two hemispheres. Employing a lateralized lexical decision task, we first showed a double dissociation between the stimulated cortical site and performance; right visual field (RVF) but not left visual field (LVF) performance was impaired when the left visual cortex was stimulated, and LVF but not RVF performance was impairred when the right visual cortex was stimulated. Unilateral stimulation also significantly impaired lexical decision latencies to centrally presented words. These findings support the suggestion that foveal representation of words is split. We discuss future strategies for the use of TMS in further tests of the split representation account.     

Memory modulated saliency: A computational model of the incremental learning of target locations in visual search

The top-down guidance of visual attention is one of the main factors allowing humans to effectively process vast amounts of incoming visual information. Nevertheless we still lack a full understanding of the visual, semantic, and memory processes governing visual attention. In this paper, we present a computational model of visual search capable of predicting the most likely positions of target objects. The model does not require a separate training phase, but learns likely target positions in an incremental fashion based on a memory of previous fixations. We evaluate the model on two search tasks and show that it outperforms saliency alone and comes close to the maximal performance of the Contextual Guidance Model (CGM; Torralba, Oliva, Castelhano, & Henderson, 2006; Ehinger, Hidalgo-Sotelo, Torralba, & Oliva, 2009), even though our model does not perform scene recognition or compute global image statistics. The search performance of our model can be further improved by combining it with the CGM.     

Job Demand–Control–Support and diabetes risk: The moderating role of self-efficacy

Work-related stressors, including high demands and low control, play a significant role in the aetiology of diabetes. Nevertheless, most studies focus on main effects, and few consider individual differences that may moderate the stress–health association. Drawing from the Job Demands–Control-–Support (JDC-S) model, this study addresses this gap by testing how baseline levels of JDC-S affect an increase in two risk factors for diabetes—glycated haemoglobin (HbA1C) and fasting plasma glucose (FPG)—and by investigating the moderating role of self-efficacy. Participants (N = 1618) were Israeli employees who attended two consecutive routine health examinations. All were free of diabetes at baseline. JDC-S and self-efficacy were assessed at baseline (T1), and HbA1C and FPG were assessed at T1 and T2. Data were analysed with logistic and linear regressions, controlling for well-established diabetes risk factors. High demands and low support predicted an increase in HbA1C and FPG. In addition, high self-efficacy interacted with high demands and with low control in the prediction of an increase in HbA1C and FPG. Although employees with high self-efficacy might function well at work, overloading them may harm their physical health. Similarly, incongruence between employees’ sense of ability and the control given to them at work may result in physical impairment.     

Working memory in the oldest-old: evidence from output serial position curves

In the present study, we examined adult age differences in short-term and working memory performance in middle-aged (45–64 years), young–old (65–74 years), old–old (75–89 years), and oldest–old adults (90 years and over) in the Louisiana Healthy Aging Study. Previous research suggests that measures of working memory are more sensitive to age effects than are simple tests of short-term memory Bopp and Verhaeghen (Journal of Gerontology: Psychological Sciences 60:223–233, 2005), Myerson, Emery, White, and Hale, (Aging, Neuropsychology, and Cognition 10:20–27, 2003). To test this hypothesis, we examined output serial position curves of recall data from three span tasks: forward and backward digit span and size judgment span. Participants’ recall patterns in the size judgment span task revealed that the two oldest groups of adults showed the largest decreases in recall performance across output serial positions, but did not differ significantly from each other. Correlation analyses indicated the strongest negative correlation with age occurred with the size judgment span task. Implications of these findings for understanding strategic processing abilities in late life are discussed.     

How accounts shape lending decisions through fostering perceived trustworthiness

We examine the roles of social accounts in influencing lenders’ decisions about loaning money to borrowers. Using field data and a laboratory experiment, we show that lenders will lend money depending on the accounts borrowers tell. In Study 1, field data from a peer-to-peer lending website reveal that two-account combinations (explanation–acknowledgment and explanation–denial) increase the likelihood of favorable lending decisions. A laboratory study helps explain the important role of accounts by unpacking the process of perceived borrower trustworthiness in lending decisions. A final field study assessing the performance of loans 2 years after origination shows that accounts, despite having a positive effect on the loan decision process, negatively predict loan performance. Collectively, the three studies show that accounts facilitate economic exchanges between unacquainted transaction partners because of their role in increasing perceived trustworthiness, but that ironically, accounts can negatively relate to loan performance.     

Estimating linear effects in ANOVA designs: The easy way

Research in cognitive science has documented numerous phenomena that are approximated by linear relationships. In the domain of numerical cognition, the use of linear regression for estimating linear effects (e.g., distance and SNARC effects) became common following Fias, Brysbaert, Geypens, and d'Ydewalle's (1996) study on the SNARC effect. While their work has become the model for analyzing linear effects in the field, it requires statistical analysis of individual participants and does not provide measures of the proportions of variability accounted for (cf. Lorch & Myers, 1990). In the present methodological note, using both the distance and SNARC effects as examples, we demonstrate how linear effects can be estimated in a simple way within the framework of repeated measures analysis of variance. This method allows for estimating effect sizes in terms of both slope and proportions of variability accounted for. Finally, we show that our method can easily be extended to estimate linear interaction effects, not just linear effects calculated as main effects.     

Using rituals in couple therapy in cases of wife battering

This article describes the work of a unit specializing in helping couples where there is violence towards the woman. It focuses particularly on ritual, describing couple violence as a type of family ritual, and outlines a number of specific healing rituals which can be substituted for the destructive ritual of violence.     

Living Under the Threat of Relocation: Spouses' Perceptions of the Threat and Coping Resources

This study examined the contribution of couples, shared perceptions of the threat of relocation, and the buffering effect of personal and marital resources in coping with stress. The study was conducted with a random sample of 95 couples in the Golan Heights region in Israel, where a unique situation exists in which families live under a threat of relocation, due to the peace negotiations between Israel and Syria. Two resources were examined: potency and marital quality Results showed that potency made the greatest contribution to coping either with demands or stress, both in couples who had similar or different future scenarios, while marital quality was found to relieve the stress only in couples who shared the same future scenarios. The average level of stress was found to be higher but not significant among couples with different future scenarios.     

The emergence of personality: Dynamic foundations of individual variation

We conceptualize personality and individual variation from the perspective of dynamical systems. People’s thoughts, feelings, and predispositions for action are inherently dynamic, displaying constant change due to internal mechanisms and external forces, but over time the flow of thought and action converges on a narrow range of states—a fixed-point attractor—that provides cognitive, affective, and behavioral stability. An attractor for personal dynamics develops through two mechanisms: the synchronization of individuals’ internal states in social interaction, and the self-organization of thoughts and feelings with respect to a higher-order property (e.g., goal, self-concept). We present formal models of both processes and instantiate each in computer simulations. Discussion centers on the implications of interpersonal synchronization and self-organization dynamics for issues in personality psychology, including shared vs. non-shared environmental influences on personality development, the expression of personality in social interaction, personal stability vs. change, personal vs. situational causation, and the emergence of self-concept.
