Towards a cognitive resource limitations model of diminished expression in schizotypy

Diminished expression of speech is a pernicious feature of both schizophrenia and schizotypy--defined as the personality organization reflecting a putative genetic schizophrenia liability. As yet, the mechanism underlying diminished expression is unclear. We tested the hypothesis that diminished expression reflects a cognitive resource issue--that is, as cognitive resources are depleted, expression becomes diminished in individuals with psychometrically defined schizotypy. Acoustic analysis of natural speech was procured during experimentally manipulated baseline and high cognitive-load dual tasks and examined in 38 individuals with psychometrically defined schizotypy and 34 controls. For both groups, expression significantly decreased as a function of increased task demands, although there were no group differences in expression or magnitude of change across baseline to high cognitive-load conditions. Participants with self-reported constricted affect showed significant reductions in expression under high-load versus baseline speaking conditions relative to other schizotypal and control participants. Moreover, psychometrically defined schizotypal participants with poor cognitive performance on the high-load task, suggestive of depleted cognitive resources, also showed expressivity reductions compared with other participants. These findings suggest that diminished expression occurs as a function of limited cognitive resources in psychometrically defined schizotypy.     

Status conferral in intergroup social dilemmas: behavioral antecedents and consequences of prestige and dominance

Bridging the literatures on social dilemmas, intergroup conflict, and social hierarchy, the authors systematically varied the intergroup context in which social dilemmas were embedded to investigate how costly contributions to public goods influence status conferral. They predicted that contribution behavior would have opposite effects on 2 forms of status-prestige and dominance-depending on its consequences for the self, in-group and out-group members. When the only way to benefit in-group members was by harming out-group members (Study 1), contributions increased prestige and decreased dominance, compared with free-riding. Adding the option of benefitting in-group members without harming out-group members (Study 2) decreased the prestige and increased the dominance of those who chose to benefit in-group members via intergroup competition. Finally, sharing resources with both in-group and out-group members decreased perceptions of both prestige and dominance, compared with sharing them with in-group members only (Study 3). Prestige and dominance differentially mediated the effects of contribution behavior on leader election, exclusion from the group, and choices of a group representative for an intergroup competition. Taken together, these findings show that the well-established relationship between contribution and status is moderated by both the intergroup context and the conceptualization of status.     

Fundamental(ist) attribution error: Protestants are dispositionally focused

Attribution theory has long enjoyed a prominent role in social psychological research, yet religious influences on attribution have not been well studied. We theorized and tested the hypothesis that Protestants would endorse internal attributions to a greater extent than would Catholics, because Protestantism focuses on the inward condition of the soul. In Study 1, Protestants made more internal, but not external, attributions than did Catholics. This effect survived controlling for Protestant work ethic, need for structure, and intrinsic and extrinsic religiosity. Study 2 showed that the Protestant-Catholic difference in internal attributions was significantly mediated by Protestants' greater belief in a soul. In Study 3, priming religion increased belief in a soul for Protestants but not for Catholics. Finally, Study 4 found that experimentally strengthening belief in a soul increased dispositional attributions among Protestants but did not change situational attributions. These studies expand the understanding of cultural differences in attributions by demonstrating a distinct effect of religion on dispositional attributions.     

Is Searching for Meaning in Life Associated With Reduced Subjective Well-Being? Confirmation and Possible Moderators

Meaning in life has been identified as an important element of well-being. Recently attention has been directed to examining the differences between having meaning in life and searching for meaning in life. Theory has speculated that if an individual is searching for meaning in life, he/she may be distressed. Researchers of late have begun to focus on the process of searching for meaning in life to gain a better understanding of the individual differences which may exist. Interest has also been directed towards exploring whether any moderators of the possible negative effects of the searching process may exist. This research investigated the hypothesised negative link between high levels of searching for meaning in life and subjective well-being and the positive moderating effects of presence of meaning in life while also exploring the influence of the demographic variables which were treated as control variables. From an exploratory stance further analysis examined the hypothesised positive moderating effects of self-actualisation, self-efficacy and achievement motives on the relationship between searching for meaning and subjective well-being. One study (n?=?500) was conducted to assess the hypothesized relationships. The study confirmed the negative relationship between high levels of searching for meaning in life and subjective well-being and positive moderating effects that presence of meaning in life and self-actualisation have on happiness scores when individuals are searching for meaning in life. Self-efficacy and achievement motives were shown to have no significant moderating effects on searching for meaning in life and subjective wellbeing. Overall the results suggest that individuals who record high levels of searching for meaning in life are protected from the negative outcomes of this process by holding high levels of presence of meaning in life and self-actualisation.     

Report from the National Society of Genetic Counselors Service Delivery Model Task Force: A Proposal to Define Models, Components, and Modes of Referral

The Service Delivery Model Task Force (SDMTF) was appointed in 2009 by the leadership of the National Society of Genetic Counselors (NSGC) with a charge to research and assess the capacity of all existing service delivery models to improve access to genetic counseling services in the context of increasing demand for genetic testing and counseling. In approaching this charge, the SDMTF found that there were varying interpretations of what was meant by "service delivery models" and the group held extensive discussions about current practices to arrive at consensus of proposed definitions for current genetic service delivery models, modes of referral and components of service delivery. The major goal of these proposed definitions is to allow for conversations to begin to address the charge to the committee. We propose that current models of service delivery can be defined by: 1) the methods in which genetic counseling services are delivered (In-person, Telephone, Group and Telegenetics), 2) the way they are accessed by patients (Traditional referral, Tandem, Triage, Rescue and Self-referral) and 3) the variable components that depend upon multiple factors unique to each service setting. This report by the SDMTF provides a starting point whereby standardized terminology can be used in future studies that assess the effectiveness of these described models to overcome barriers to access to genetic counseling services.     

Genetic Counseling and Testing for FSHD (Facioscapulohumeral Muscular Dystrophy) in the Israeli Population

Facioscapulohumeral muscular dystrophy (FSHD), is a dominantly inherited, late onset, progressive disease. At present, no treatment or prevention of symptoms are available. There is considerable clinical variability, even within families. The gene whose defect causes FSHD has not been identified, but molecular diagnosis can be made by analyzing D4Z4 repeat length on chromosome 4q35. The results can support or rule out the clinical diagnosis of FSHD, but there are also "gray zone", non-conclusive results. During the years 2000-6, 66 individuals (including 7 asymptomatic individuals), were tested in our institute for D4Z4 repeat number. In 77% of the cases the results were conclusive: two thirds of them supported a diagnosis of FSHD while in a third this diagnosis was ruled out. In 23% the results were in the gray zone. Cognitive involvement was rare, occurring only when the D4Z4 repeat size was very small (<15 kb). Maximal utilization of the existing molecular test for FSHD demands detailed clinical and family pedigree information. We recommend that comprehensive genetic counseling always be given before and after molecular testing for FSHD, in addition to the neurological follow-up. Presymptomatic testing should only be offered when complete molecular evaluation can be offered, including 4qA and 4qB variant analysis.     

THE MIGRATIONS OF MOROCCAN JEWS TO MONTREAL: MEMORY, (ORAL) HISTORY AND HISTORICAL NARRATIVE

Among the masses of migrant populations driven to leave their countries against the backdrop of European decolonialization, North African Jews occupy a special place. Within several competing versions of the history of Moroccan Jews, recent historiographical debates reveal the political and memorial importance that this history represents for its various participants. Because the boundaries of memory are unstable, this article aims at understanding the interactions between memory and history. It outlines, first, the historical and historiographical context and presents the results of two oral history surveys, one conducted in the 1980s (N?=?27 in 1984–1986), the other more recently (N?=?15 in 2009–2010), and which draw upon a collection of life stories of men and women who left Morocco and went to Montreal in the 1980s and 1990s. It presents their answers to the questions of the circumstances under which these migrations took place and their memories of them today. These stories could then be transcribed and transmitted within a narrative that embodies both its historical meaning and their memory of it. Within this coping system, which denies the trauma associated with their departure en masse from Morocco, the interviewees hope to be considered as full members of the Sephardi diaspora and as Quebec citizens.
