Examining mental simulations of uncertain events

A great deal of research into the experiential nature of language has demonstrated that our understanding of events is facilitated through mental simulations of the described linguistic input. However, to date little is understood about how contextual uncertainty about the described event might influence the content and strength of these mental representations or the cognitive effort involved. In this article, we report a single experiment in which participants read sentences such as “The old lady [knows/thinks] that the picnic basket is open.” Following a delay of 250 or 1,500 ms, they responded to pictures that varied in the physical form of the target object (matching vs. mismatching). Results revealed an expected facilitation effect for matching images, but more important, they also showed interference effects (longer reaction times) at the shorter interstimulus interval (ISI; 250 ms) following the uncertain verb thinks, as compared with the certain verb knows. At the longer ISI, this effect was no longer present. This suggests that at the short ISI, uncertain conditions required extra time to construct and map a simulation of events onto the available image. Results are discussed in terms of the mechanisms involved in representing possible events and with reference to related literature on perspective taking.     

Factors Associated With Adverse Mental Health Outcomes in Locally Recruited Aid Workers Assisting Iraqi Refugees in Jordan

Nongovernmental organizations (NGOs) serve Iraqis living in Jordan as “guests.” In 2008, 258 Jordanian humanitarian staff and Iraqi volunteers working for NGOs completed a needs assessment survey. Work characteristics, stressors, and support variables were evaluated regarding their influence on depression, anxiety, post-traumatic stress disorder (PTSD), and burnout through multivariate logistic regressions. There was a significant difference in depression, anxiety, and burnout across nationality. Traumatic exposure increased the risk for anxiety, depression, and PTSD. Working longer in the humanitarian sector was associated with less risk of anxiety and depression, and lower social support was a risk for anxiety. Managers were at higher risk for burnout, and low team cohesion was a risk for burnout. Implications for aid organizations are discussed.     

The interactive effects of person-focused citizenship behaviour,task interdependence,and virtuality on team performance

A multifactorial between-groups experiment examined the effects of person-focused organizational citizenship behaviours (OCBP) on the performance of teams characterized by different levels of virtuality and task interdependence. Results reveal in low virtual teams the moderating effects of task interdependence on the OCBP–team performance relationship are positive; however, these effects are reversed in high virtual teams. Using social presence and task–technology fit theories, our results indicate that task context affects how OCBP impacts team performance, particularly across different levels of team virtuality. The implications for research on OCB and the management of virtual teams are discussed.     

The Effects of Prenatal Alcohol Exposure on Behavior: Rodent and Primate Studies

The use of alcohol by women during pregnancy is a continuing problem. In this review the behavioral effects of prenatal alcohol from animal models are described and related to studies of children and adults with FASD. Studies with monkeys and rodents show that prenatal alcohol exposure adversely affects neonatal orienting, attention and motor maturity, as well as activity level, executive function, response inhibition, and sensory processing later in life. The primate moderate dose behavioral findings fill an important gap between human correlational data and rodent mechanistic research. These animal findings are directly translatable to human findings. Moreover, primate studies that manipulated prenatal alcohol exposure and prenatal stress independently show that prenatal stress exacerbates prenatal alcohol-induced behavioral impairments, underscoring the need to consider stress-induced effects in fetal alcohol research. Studies in rodents and primates show long-term effects of prenatal and developmental alcohol exposure on dopamine system functioning, which could underpin the behavioral effects.     

Empowering or oppressing? Development and exploration of the Enjoyment of Sexualization Scale

Sexualization of girls and women in America is rampant and has many negative consequences. Women, however, often report enjoying being sexually admired by men. Given this paradox, it is unclear whether such enjoyment represents an authentic empowerment of women's sexuality or is related to traditional feminine norms and sexist beliefs. In Studies 1 and 2, the authors developed and tested the eight-item Enjoyment of Sexualization Scale (ESS). It had good reliability and was differentiated from related constructs including body surveillance, body shame, self-sexualizing behaviors, and appearance-contingent self-esteem. In Study 3, endorsement of traditional gender norms, endorsement of benevolent sexism, and endorsement of hostile sexism were all positively related to the ESS. Moreover, women who both enjoyed sexualization and engaged in self-objectification reported more negative eating attitudes. Overall, there was little support for positive effects of enjoying sexualization. The extent to which enjoying sexualization actually empowers women or contributes to their oppression is discussed.     

Dekonstruktion der ?Ambivalenz��

Focusing on the relation between discourse and subject formation, the poststructuralistic reiterations and resignifications within the concept of ambivalence provide important aspects for a contemporary conceptualization of ambivalence, especially within the framework of educational theory (Bildungstheorie). From this point of view the paper explores firstly the notion of ??ambivalence?? in the context of Derrida??s theory and practice of deconstruction and secondly the relation between ??ambivalence?? and ??ambiguity?? considering Derrida??s theory of ??différance?? and Butler??s theory of ??performativity??. Finally the article outlines the meaning of ??ambivalence?? in Butler??s theory of the subjectivation process.     

Attentional disengagement in adults with Williams syndrome

Williams syndrome (WS) is a neurodevelopmental disorder characterized by a distinctive behavioral and cognitive profile, including widespread problems with attention. However, the specific nature of their attentional difficulties, such as inappropriate attentional allocation and/or poor attentional disengagement abilities, has yet to be elucidated. Furthermore, it is unknown if there is an underlying difficulty with the temporal dynamics of attention in WS or if their attentional difficulties are task-dependent, because previous studies have examined attention in established areas of deficit and atypicality (specifically, visuospatial and face processing). In this study, we examined attentional processing in 14 adults with WS (20–59 years) and 17 typically developing controls (19–39 years) using an attentional blink (AB) paradigm. The AB is the decreased ability to detect a second target when it is presented in close proximity to an initial target. Overall, adults with WS had an AB that was prolonged in duration, but no different in magnitude, compared with typically developing control participants. AB performance was not explained by IQ, working memory, or processing speed in either group. Thus, results suggest that the attention problems in WS are primarily due to general attentional disengagement difficulties rather than inappropriate attentional allocation.     

The single interval adjustment matrix (SIAM) yes–no task: an empirical assessment using auditory and gustatory stimuli

The SIAM yes-no task is an efficient bias-free adaptive procedure for estimating absolute thresholds, though it arguably requires further evaluation prior to its adoption into mainstream psychological research. We report two experiments undertaken in the auditory and gustatory modalities designed to assess the accuracy and efficiency of the SIAM method. In the first experiment, estimates of absolute thresholds for 1000-Hz tones obtained using a two-alternative forced choice adaptive procedure were compared to those obtained using both the SIAM yes-no task and a modification of the SIAM task incorporating the method of free response, the SIAM-rapid. In Experiment 2, we compared absolute thresholds for sucrose in solution obtained with either a two-alternative forced choice adaptive procedure or the SIAM yes-no task. Both experiments demonstrated the efficiency and validity of the SIAM approach, with SIAM thresholds proving to be equivalent to those obtained in the two-alternative forced choice tasks and to those reported in the literature.     

Is an outgroup member in need a friend indeed? Personal and task‐oriented contact as predictors of intergroup prosocial behavior

Intergroup contact, particularly close personal contact, has been shown to improve intergroup relations, mainly by reducing negative attitudes and emotions toward outgroups. We argue that contact can also increase intergroup prosocial behavior. More specifically, we predict that different forms of contact will differentially impact on prosocial behavior directed at individual outgroup members and outgroups as a whole. Data of two studies (N₁ = 264, N₂ = 185), conducted with workgroups in two organizations, show that personal contact is a better predictor of prosocial behavior directed at individual outgroup members, whereas task‐oriented contact is a better predictor of prosocial behavior directed at an outgroup as a whole. Additionally, Study 2 provides evidence that empathy mediates the path from personal contact to individual‐directed prosocial behavior, whereas reward (but not cost) considerations mediate the path from task‐oriented contact to outgroup‐directed prosocial behavior. Implications for research on intergroup contact and prosocial behavior are discussed. Copyright © 2012 John Wiley & Sons, Ltd.     

Feminism and Attachment Parenting: Attitudes, Stereotypes, and Misperceptions

This paper investigated attitudes and stereotypes about what feminist women, primarily from the United States, believed about a number of practices associated with attachment parenting which is theorized to be both feminist and non-feminist. The goals of this study were to determine whether feminists endorsed attachment parenting and whether stereotypes of feminists’ beliefs corresponded to actual feminists’ attitudes. Women were recruited online, primarily through blogs, to complete an online survey about feminism and mothering. Four hundred and thirty one women comprised the sample for the current investigation and included heterosexual-identified feminist mothers (n?=?147), feminist non-mothers (n?=?75), non-feminist mothers (n?=?143), and non-feminist non-mothers (n?=?66). Participants were asked to rate their own attitudes towards specific practices associated with attachment parenting and to indicate their perceptions of the beliefs of the typical feminist. Results indicated that feminists were more supportive of attachment parenting practices than were non-feminists. Non-feminists, particularly mothers, held misperceptions about the typical feminist, seeing them as largely uninterested in the time-intensive and hands-on practices associated with attachment parenting. Feminist mothers also held stereotypes about feminists and saw themselves as somewhat atypical feminists who were more interested in attachment parenting than they thought was typical of feminists. Our data indicated that feminists did endorse attachment parenting and that stereotypes of feminists related to attachment parenting are untrue. Furthermore, the role of feminism in the identity of feminist mothers and whether attachment parenting is truly a feminist way to parent are discussed.
