Perceived social isolation and cognition

A MUCH debated question is whether sex differences exist in the functional organization of the brain for language1–4. A long-held hypothesis posits that language functions are more likely to be highly lateralized in males and to be represented in both cerebral hemispheres in females5,6, but attempts to demonstrate this have been inconclusive7–17. Here we use echo-planar functional magnetic resonance imaging18–21 to study 38 right-handed subjects (19 males and 19 females) during orthographic (letter recognition), phonological (rhyme) and semantic (semantic category) tasks. During phonological tasks, brain activation in males is lateralized to the left inferior frontal gyrus regions; in females the pattern of activation is very different, engaging more diffuse neural systems that involve both the left and right inferior frontal gyrus. Our data provide clear evidence for a sex difference in the functional organization of the brain for language and indicate that these variations exist at the level of phonological processing.

Social Phobia: Diagnosis, Assessment, and Treatment

Four studies tested whether nostalgia can counteract reductions in perceived social support caused by loneliness. Loneliness reduced perceptions of social support but increased nostalgia. Nostalgia, in turn, increased perceptions of social support. Thus, loneliness affected perceived social support in two distinct ways. Whereas the direct effect of loneliness was to reduce perceived social support, the indirect effect of loneliness was to increase perceived social support via nostalgia. This restorative function of nostalgia was particularly apparent among resilient persons. Nostalgia is a psychological resource that protects and fosters mental health.

Counteracting Loneliness On the Restorative Function of Nostalgia

Social exclusion and monetary loss are perceived as painful. The pain produced by these two kinds of events shares similar psychological and physiological systems with physical pain. Thus, physical pain, social pain, and monetary-loss pain were generally regarded as overlapping pain systems in previous theories. In this article, we propose that social exclusion is painful because it is a threat to a primary psychological buffer against pain—social support—whereas monetary loss is painful because money is a secondary pain buffer. Here both social support and money are conceptualized as pain buffers. We review a growing body of empirical data that support this contention. On the basis of a comprehensive analysis of the sociocultural and personal functions of social support and money, we formulate two basic hypotheses that have received empirical support. First, anticipation of pain heightens the desire for social support as well as the desire for money. Second, both social support and money reminders allevi...

Social Support and Money as Pain Management Mechanisms

Purpose Our pilot studies showed that there was a significant relationship between blood lead levels of women at the first trimester and scores of neonatal behavioral neurological assessment (NBNA). This study went further (1) to determine particular neurotoxicity during a specific trimester, (2) to analyze “safe” levels of Pb in neonates, and (3) to identify influencing factors for prenatal Pb exposure. Method A total of 415 mothers with newborn located Shenzhen, Guangdong, China participated in the study: 219 in the high lead group [blood lead levels (BLLs) at first trimester ≥ 4.89 μg/dl] and 196 in the low lead group [BLLs ≤ 1.96 μg/dl]. The maternal BLLs at each stage of pregnancy and delivery were measured by atomic absorption spectrophotometry, equipped with a graphite furnace. The developmental functioning of newborns was assessed with NBNA in 3 days. The children's birth outcome and the rest of information was obtained from their medical records or a comprehensive questionnaire from their parents, which contained demographic characteristics, lifestyle, IQ, occupation and influencing factors for lead exposure during and before first trimester, etc. Results Of 415 newborns, 332 (80.00%) had complete data collection for all variables at four-stage follow-up. The maternal mean BLL at first trimester for 332 newborns was 3.98 ± 1.15 μg/dl (0.38–15.86 μg/dl) and the geometric mean (GM) was 3.63 ± 0.35 μg/dl (95%CI: 2.98–4.32 μg/dl). In total, about 4.82% of newborns had maternal BLLs > 10 μg/dl. Significant inverse associations have been found between the maternal BLLs at the first trimester and the NBNA scores (P  Conclusion Our study demonstrate that fetal lead exposure as low as 5 μg/dl has an adverse effect on neurodevelopment, most expressed during the first trimester and best arrested by measuring maternal BLLs. The collective evidence indicates that screening and intervention after the first trimester may be too late to prevent the fetal neurotoxic effects.

The authors propose a new procedure for reducing faking on personality tests within selection contexts. This computer-based procedure attempts to identify and warn potential fakers early on during the testing process and then give them a chance for recourse. Two field studies were conducted to test the efficacy of the proposed procedure. Study 1 participants were 157 applicants competing for 10 staff positions at a large university located in a southern city in the People’s Republic of China. In Study 1, potential fakers received a warning message, whereas nonfakers received a nonwarning (control) message. Study 2 participants were 386 Chinese college students applying for membership of a popular student organization at the same university where Study 1 was conducted. In Study 2, the warning and control messages were randomly assigned to all applicants. Results showed some promise for the proposed procedure, but several practical issues need to be considered.

Using a battery of working memory span tasks and n-back tasks, this study aimed to explore working memory functions in early-school-age children with Asperger's syndrome (AS). Twelve children with AS and 29 healthy children matched on age and IQ were recruited. Results showed: (a) children with AS performed better in digit and word recall tasks, but worse in block recall task and variant-visual-patterns test; (b) children with AS took longer time in most conditions of n-back tasks, and showed larger effects of task load. These findings indicated imbalance of working memory development in AS children: they had advantage in the phonological loop storing, but disadvantage in the visuospatial sketchpad storing, and partial deficit in central executive.
