A Meta-Analysis of Working Memory Impairments in Autism Spectrum Disorders

Autism spectrum disorders (ASD) are characterized by executive dysfunction, and working memory (WM) comprises one core component of executive function. Many studies have investigated WM impairments in individuals with ASD, however, a conclusive agreement has not been reached. The present study provided a meta-analytic review of WM impairments in individuals with ASD and evaluated potential moderating variables of this problem. Twenty-eight studies were included in this study, and the participants comprised 819 individuals with ASD and 875 healthy controls. A significant WM impairment (Cohen’s d?=??0.61) was identified in the individuals with ASD, however, this impairment was not associated with age. Results of moderation analyses showed that (a) spatial WM was more severely impaired than verbal WM and (b) the component of cognitive processing (maintenance vs. maintenance plus manipulation) did not affect the severity of WM impairments. These findings suggest that WM is impaired in individuals with ASD and may have implications for interventions related to WM impairments in these individuals.     

Social contexts modulate neural responses in the processing of others’ pain: An event-related potential study

Two hypotheses have been proposed regarding the response that is triggered by observing others’ pain: the “empathizing hypothesis” and the “threat value of pain hypothesis.” The former suggests that observing others’ pain triggers an empathic response. The latter suggests that it activates the threat-detection system. In the present study, participants were instructed to observe pictures that showed an anonymous hand or foot in a painful or non-painful situation in a threatening or friendly social context. Event-related potentials were recorded when the participants passively observed these pictures in different contexts. We observed an interaction between context and picture in the early automatic N1 component, in which the painful pictures elicited a larger amplitude than the non-painful pictures only in the threatening context and not in the friendly context. We also observed an interaction between context and picture in the late P3 component, in which the painful pictures elicited a larger amplitude than the non-painful pictures only in the friendly context and not in the threatening context. These results indicate that specific social contexts can modulate the neural responses to observing others’ pain. The “empathic hypothesis” and “threat value of pain hypothesis” are not mutually exclusive and do not contradict each other but rather work in different temporal stages.     

Competence in early adult romantic relationships: a developmental perspective on family influences

The present prospective, longitudinal study of 193 young adults (85 men, 108 women, M = 20.7 years old) and their partners in ongoing romantic relationships in 1997 was initiated in 1989, when the 193 target youths were in the 7th grade. On the basis of the model for the development of early adult romantic relationships (DEARR; C. Bryant & R. D. Conger, in press), the authors hypothesized that interactional processes in the family of origin would predict interpersonal skills by the target youths, which would be positively related to the early adult couple's relationship quality. Observational ratings showed that nurturant-involved parenting in the family of origin predicted behaviors by the target youth to a romantic partner that were warm, supportive, and low in hostility. These competent behaviors of the target youth were positively associated with relationship quality for the early adult couple and also mediated or explained the connection between parenting and relationship quality.

Male vocal competition is dynamic and strongly affected by social contexts in music frogs

Male–male vocal competition in anuran species is critical for mating success; however, it is also highly time-consuming, energetically demanding and likely to increase predation risks. Thus, we hypothesized that changes in the social context would cause male vocal competition to change in real time in order to minimize the costs and maximize the benefits of competition. To test this hypothesis, we assessed the effect of repeating playbacks of either white noise (WN) or male advertisement calls on male call production in the Emei music frog (Babina daunchina), a species in which males build mud-retuse burrows and call from within these nests. Previous studies have shown that calls produced from inside burrows are highly sexually attractive (HSA) to females while those produced outside nests are of low sexual attractiveness (LSA). Results showed that most subjects called responsively after the end of WN playbacks but before the onset of conspecific call stimuli although call numbers were similar, indicating that while males adjusted competitive patterns according to the biological significance of signals, their competitive motivation did not change. Furthermore, these data indicate that the frogs had evolved the ability of interval timing. Moreover, when the inter-stimulus interval (ISI) between playbacks was varied, the subjects preferentially competed with HSA calls when the ISI was short (<4 s) but responded equally to HSA and LSA calls if the ISI was long (≥4 s), suggesting that males allocate competitive efforts depending on both the perceived sexual attractiveness of rivals and the time available for calling. Notably, approximately two-thirds of male calls occurred in response to HSA calls, a preference rate comparable to that previously found for females in phonotaxis experiments and consistent with the idea that the mechanisms underlying both the male’s competitive responses to rivals and the female’s preferences toward potential mates coevolved under the same selective pressure.     

Dynamics of the relationships among work and family resource gain and loss,enrichment, and conflict over time

Dynamics of the relationships among work and family resource gain and loss, work-to-family enrichment (WFE), and work-to-family conflict (WFC) over time were examined using the data collected from 382 employees of Chinese firms at two points of time one year apart. Work resource gain at time 1 weakened the positive relationship between WFC at times 1 and 2, and work resource loss at time 1 weakened the positive relationship between WFE at times 1 and 2. However, WFC at time 1 strengthened the positive relationship between work resource gain at time 1 and family resource gain at time 2. Overall, these results suggest the existence of complementary forces that maintain the status quo of individuals' work–family experiences, such that high losses diminish the transfer of gains and high gains diminish the transfer of losses, but also that unexpected gains may result from individuals having to deal with painful situations. Implications of these dynamics for theory, research, and practice are discussed.     

Depression in primary Sjögren’s syndrome: a systematic review and meta-analysis

There is substantial uncertainty regarding the prevalence of depression in Primary Sjögren’s syndrome (pSS). We conducted a systematic review aiming to evaluate the association of pSS with depression. PubMed, Web of Science, VIP, CNKI and Wanfang database were searched to find the published literatures (from these databases established to October 2016). Studies were screened according to inclusion and exclusion criteria and the qualities of included studies were evaluated. The data was analyzed using Revman5.2 software. A total of 12 studies including 1917 patients were eligible for inclusion in the systematic review and meta-analysis. In this meta-analysis, Severity of depression was assessed using psychometric measures, such as PHQ-9; HADS; CES-D; Zung depression scale and BDI. The result revealed that pSS was associated with an increased prevalence of depression (summary odds ratio (OR) = 5.36, 95% CI: 4.05–7.09, P < 0.01). The depression score in pSS patients (standardized mean difference (SMD) = 1.47, 95% CI: 0.81–2.12, P < 0.01) were higher than in the control group. Depression is highly prevalent in pSS than in healthy controls. Early recognition and appropriate intervention are therefore essential to reduce the negative impact of depression on the patient’s quality of life and outcome of their disease.     

Systemic lupus erythematosus is associated with negatively variable impacts on domains of sleep disturbances: a systematic review and meta-analysis

Sleep disturbances are common in systemic lupus erythematosus (SLE), but the features of sleep disturbances are not well understood. The aim of this study was to identify the impact of SLE on specific sleep quality domains and to determine its prevalence and associations. We performed a systematic review and meta-analysis to compare the sleep outcomes of individuals with SLE and healthy controls. PubMed, MEDLINE, EMBASE, Cochrane Library, Web of Science CNKI, VIP, CNKI and Wanfang database were searched to find the published literatures (from these databases established to May 2017). Studies were screened according to inclusion and exclusion criteria and the qualities of included studies were evaluated. The data was analyzed using Revman5.3 software. Score of the Pittsburgh Sleep Quality Index (PSQI) scoring system was used as the outcome measurement, and mean differences (MD) with 95% confidence intervals (CI) were calculated. Five studies were included, including 350 SLE and 1396 healthy controls. A total of 5 studies including 827 patients were eligible for inclusion in the systematic review and meta-analysis. In this meta-analysis, each domain of the PSQI score: subjective sleep quality (MD, .58; 95% CI, .26, .89), sleep latency(MD, .47; 95% CI, .21, .73), sleep duration (MD, .36; 95% CI, .13, .58), habitual sleep efficiency (MD, .58; 95% CI, .32, .84),sleep disorders (MD, .56; 95% CI, .34, .77), use of sleep medication (MD, .56; 95% CI, .33, .80), daytime dysfunction (MD, .57; 95% CI, .11, 1.04) and the global score (MD, 3.59; 95% CI, 1.37, 5.80) were higher in SLE women than healthy controls. Furthermore, subjective sleep quality and habitual sleep efficiency were most severely affected especially. It demonstrated that targeted interventions should be done to improve their sleep quality. Early recognition and appropriate intervention are essential to reduce the negative impact of sleep disturbances on the patient’s sleep quality and outcome of their disease.
