Performance on a face perception task is associated with empathy quotient scores, but not systemizing scores or participant sex

This preliminary study investigated whether individual differences in performance on a difficult social perception task (determining the sex of shape normalized, line drawn dynamic faces) are related to sex of observer, scores on an empathy quotient and scores on a systemizing quotient. Performance in the face perception task (N = 60) was above chance, indicating that participants could judge the sex of the degraded facial stimuli from dynamic information alone. There was a trend for women to be more accurate in their judgments of target sex than men, but regression analyses indicated that EQ scores alone predicted performance on the task. This study suggests that empathy may mediate sex differences in face perception abilities, and potentially other tasks in social perception.

Parental Efficacy Moderates the Association Between Empathy and Burden Among Parents of Children Admitted to a Psychiatric Ward

Empathy is considered a positive aspect of caregiving, although in certain circumstances, being empathic might increase the burden of caregivers. The current study assessed the associations between empathy, parental efficacy, and family burden among parents of children who were hospitalized in a psychiatric unit. Specifically, we examined whether the association between empathy and family burden was moderated by the parents’ sense of self-efficacy. Seventy parents of children with psychiatric disorders, hospitalized in an inpatient psychiatric unit, filled out questionnaires of empathy, parental efficacy, and family burden. Results supported a moderating role of parental efficacy between empathy and family burden (interaction effect: β = −1.72, p = .0406). Specifically, empathy was positively related to family burden among parents with low self-efficacy (conditional effect = 0.70, p = .032) and negatively related to family burden among parents with high self-efficacy (conditional effect = −0.39, p = N.S). Implications for practice include the importance of self-efficacy and address the possible negative implications of empathy among parents of children treated in a psychiatric hospital.     

Different routes to limited empathy in the sexes: Examining the links between the Dark Triad and empathy

A fundamental observation regarding the Dark Triad traits (i.e., narcissism, psychopathy, and Machiavellianism) is that they are all associated with limited empathy. However, little is known about these relationships beyond some basics. In this study (N = 352), we asked three questions. What is the nature of the relationship between the Dark Triad traits and empathy? Does limited empathy account for sex differences in the Dark Triad? Are men and women low on empathy through different personality traits? The Dark Triad traits were all related to low levels of empathy even when controlling for the shared variance among the traits. Empathy rates mediated sex differences in different aspects of the Dark Triad but not others. Low empathy rates were related to narcissism in women but psychopathy in men, suggesting different routes to limited empathy for men and women high on the Dark Triad.     

Too great to act in solidarity: The negative relationship between collective narcissism and solidarity-based collective action

Three studies examined the association between narcissistic identification with one’s advantaged in-group and engagement in solidarity-based collective action. Drawing on theory and past research, a negative effect of collective narcissism on solidarity-based collective action was expected. A two-wave longitudinal study (N = 162) found that Polish participants’ narcissistic, but not secure, national identification decreased their willingness to engage in collective action in solidarity with refugees over time. A field study (N = 258) performed during a mass protest against a proposed abortion ban showed that men’s gender-based collective narcissism was a negative predictor of solidarity-based engagement (operationalized as protest behavior and collective action intentions) and this effect was mediated by lowered empathy for women. Finally, a web-based survey (N = 1,992) revealed that heterosexual/cisgender individuals’ collective narcissism was negatively associated with collective action intentions in support of LGBT rights and that this effect was sequentially mediated by increased intergroup anxiety and decreased empathy for LGBT people. Theoretical implications of the present findings, research limitations, and future directions are discussed.     

Visual configural processing in adults born at extremely low birth weight

Being born at extremely low birth weight (ELBW; ≤1,000 g) is associated with enduring visual impairments. We tested for long‐term, higher order visual processing problems in the oldest known prospectively followed cohort of ELBW survivors. Configural processing (spacing among features of an object) was examined in 62 adults born at ELBW (M_age = 31.9 years) and 82 adults born at normal birth weight (NBW; ≥2,500 g: M_age = 32.5 years). Pairs of human faces, monkey faces, or houses were presented in a delayed match‐to‐sample task, where non‐matching stimuli differed only in the spacing of their features. Discrimination accuracy for each stimulus type was compared between birth weight groups, adjusting for neurosensory impairment, visual acuity, binocular fusion ability, IQ, and sex. Both groups were better able to discriminate human faces than monkey faces (p < .001). However, the ELBW group discriminated between human faces (p < .001), between monkey faces (p < .001), and to some degree, between houses (p < .06), more poorly than NBW control participants, suggesting a general deficit in perceptual processing. Human face discrimination was related to performance IQ (PIQ) across groups, but especially among ELBW survivors. Coding (a PIQ subtest) also predicted human face discrimination in ELBW survivors, consistent with previously reported links between visuo‐perceptive difficulties and regional slowing of cortical activity in individuals born preterm. Correlations with Coding suggested ELBW survivors may have used a feature‐matching approach to processing human faces. Future studies could examine brain‐based anatomical and functional evidence for altered face processing, as well as the social and memory consequences of face‐processing deficits in ELBW survivors.     

When is narcissism associated with low empathy? A meta-analytic review

Narcissism is commonly associated with low empathy, but empirical studies have used diverse methods, yielding mixed findings. The present meta-analysis examined the overall magnitude of the association between grandiose and vulnerable narcissism and affective and cognitive empathy (N = 32200). Grandiose narcissism was significantly negatively associated with self-reported cognitive (r = −0.085) and affective (r = −0.145) empathy. When empathy was measured behaviourally, grandiose narcissism was significantly associated only with affective empathy (r = −0.251) but not cognitive empathy (r = −0.052). Vulnerable narcissism was significantly negatively associated with self-reported cognitive and affective empathy (r = −0.179 and r = −0.105 respectively). The association between vulnerable narcissism and cognitive empathy measured behaviourally was not significant (r = −0.069). The association between narcissism and empathy is nuanced and depends on various conceptual and methodological factors.     

Study of Sexual Concordance in Men and Women with Different Typologies of Adherence to the Sexual Double Standard

Background/ObjectiveSexual concordance (i.e., relationship between genital response and subjective sexual arousal) is higher in men than in women. Among the factors that could explain this difference would be the sexual double standard (SDS). Sexual concordance is examined by SDS typologies of adherence (egalitarian, man-favorable, and woman-favorable).MethodDuring exposure to a film with sexual content, genital response (penile circumference/vaginal pulse amplitude) and self-reported sexual arousal were recorded in 104 young adults (42 men and 62 women), distributed into SDS typologies of adherence on the basis of their scores on the Sexual Double Standard Scale.ResultsSexual concordance was obtained in men and women with egalitarian and man-favorable typology. Subjective sexual arousal explained a significant percentage of the variance in genital response in the egalitarian typology (men: R² = .32, p < .01; women: R² = .19, p < .05) and man-favorable typology (men: R² = .21, p < .05; women: R² = .23, p < .05).ConclusionsAgreement between genital responsiveness and subjective sexual arousal depends on DES adherence typology.     

Women are more sensitive than men to prior trial events on the Stop‐signal task

Sexual dimorphism in the brain and cognition is a topic of widespread interest. Many studies of sex differences have focused on visuospatial and verbal abilities, but few studies have investigated sex differences in executive functions. We examined two key components of executive function – response inhibition and response monitoring – in healthy men (n = 285) and women (n = 346) performing the Stop‐signal task. In this task, participants are required to make a key press to a stimulus, unless a tone is presented at some delay following the initial stimulus presentation; on these infrequent trials, participants are instructed to inhibit their planned response. Response inhibition was assessed with an estimate of the latency needed to inhibit a response (stop‐signal reaction time), and response monitoring was measured by calculating the degree to which participants adjusted their reaction times based on the immediately preceding trial (e.g., speeding following correct trials and slowing following errors). There were no sex differences in overall accuracy or response inhibition, but women showed greater sensitivity to trial history. Women sped up more than men following correct ‘Go’ trials, and slowed down more than men following errors. These small but statistically significant effects (Cohen's d = 0.25–0.3) suggest more flexible adjustments in speed–accuracy trade‐offs in women and greater cognitive flexibility associated with the responsive control of action.     

Letting go of your dreams—Adjustment of child-related goal appraisals and depressive symptoms during infertility treatment

To examine the adjustment of child-related goal appraisals during infertility treatment and whether such adjustment contributes to depressive symptoms 178 (86 men, 92 women; age for women M = 33.92, SD = 0.34, for men M = 35.68, SD = 0.45) patients at an Infertility Clinic filled in child-related goal appraisal questionnaires six times: (1) before starting the hormone injections, (2) before the oocytes were retrieved, (3) after embryo transfer, (4) the day when the pregnancy test was done, and (5) two and (6) six months after the infertility treatment. At the first and last measurement times they filled in questionnaire on depressive symptoms. Appraisals concerning child-related goal changed in tandem with the treatment result, and goal adjustment had an effect on depressive symptoms.     

Relationship between coping styles and perceptual asymmetry

This study examined the relationship between coping styles and hemispheric asymmetry, on the basis of prior evidence of reduced posterior right hemisphere (RH) activity in depression, and the relationship between ruminative coping and depression. Two samples of undergraduates (N = 170) completed chimeric faces tasks and 2 measures of coping styles, the self-report Responses Styles Questionnaire and a behavioral choice task. In women but not in men, self-reported rumination was associated with a decreased RH bias on the emotion-based chimeric task. In both genders, choosing to engage in an emotional task was associated with increased RH involvement. Results indicate that although brooding and dwelling on the negative may be associated with decreased RH involvement, openness to emotion may be associated with increased RH involvement.     

Mindfulness Meditation for Symptom Reduction in Fibromyalgia: Psychophysiological Correlates

Objectives Fibromyalgia, a chronic pain syndrome, is often accompanied by psychological distress and increased basal sympathetic tone. In a previous report it was shown that mindfulness-based stress-reduction (MBSR) reduced depressive symptoms in patients with fibromyalgia with gains maintained at two months follow-up (Sephton et al., Arthr Rheum 57:77–85, 2007). This second study explores the effects of MBSR on basal sympathetic (SNS) activation among women with fibromyalgia. Methods Participants (n = 24) responded to a television news appearance, newspaper, and radio advertisements. Effects on anxiety, depressive symptoms, and SNS activation measures were tested before and after MBSR using a within-subjects design. Results The MBSR treatment significantly reduced basal electrodermal (skin conductance level; SCL) activity (t = 3.298, p = .005) and SCL activity during meditation (t = 4.389, p = .001), consistent with reduced SNS activation. Conclusions In this small sample, basal SNS activity was reduced following MBSR treatment. Future studies should assess how MBSR may help reduce negative psychological symptoms and attenuate SNS activation in fibromyalgia. Further clarification of psychological and physiological responses associated with fibromyalgia may lead to more beneficial treatment.     

Effects of sleep on positive,negative and neutral valenced story and image memory

During sleep, emotional memories are preferentially strengthened. However, most studies on sleep and emotional memory focus on comparing negative valence with neutral valence stimuli. This study compared the sleep-dependent memory effects for stories and images, each comprising negative, neutral, and positive stimuli. It was hypothesized that a sleep effect would be seen for negatively and positively valenced stimuli. A novel story memory task (comprising three stories), and photographs from the Nencki Affective Picture database were presented for learning to 61 healthy adults (ages 18–25). They were tested for memory on the two tasks immediately, and then again after either a 2-hr nap (n = 31; 17 women, 14 men) or 2-hr wake period (n = 30; 13 women, 17 men). At second testing, the sleep condition had significantly better recall compared to the wake condition on both tasks. There was a relationship with valence only for the story task, with better performance for the sleep condition on the negatively and positively valenced texts, but not on the neutral text. There were no significant relationships between memory measures and sleep-stage duration and EEG power variables. The story memory findings support the hypothesis that memory consolidation prioritizes emotional memory, whether positively or negatively valenced.     

The telltale face: Possible mechanisms behind defector and cooperator recognition revealed by emotional facial expression metrics

In this study, we investigated the role of facial cues in cooperator and defector recognition. First, a face image database was constructed from pairs of full face portraits of target subjects taken at the moment of decision‐making in a prisoner's dilemma game (PDG) and in a preceding neutral task. Image pairs with no deficiencies (n = 67) were standardized for orientation and luminance. Then, confidence in defector and cooperator recognition was tested with image rating in a different group of lay judges (n = 62). Results indicate that (1) defectors were better recognized (58% vs. 47%), (2) they looked different from cooperators (p < .01), (3) males but not females evaluated the images with a relative bias towards the cooperator category (p < .01), and (4) females were more confident in detecting defectors (p < .05). According to facial microexpression analysis, defection was strongly linked with depressed lower lips and less opened eyes. Significant correlation was found between the intensity of micromimics and the rating of images in the cooperator‐defector dimension. In summary, facial expressions can be considered as reliable indicators of momentary social dispositions in the PDG. Females may exhibit an evolutionary‐based overestimation bias to detecting social visual cues of the defector face.     

Transcranial direct-current stimulation enhances implicit motor sequence learning in persons with Parkinson's disease with mild cognitive impairment

Implicit motor sequence learning (IMSL) is affected in Parkinson's disease (PD). Research in healthy young participants shows the potential for transcranial direct-current stimulation (tDCS) over the primary motor cortex (M1) to enhance IMSL. In PD, only null effects have been reported to date. We determined concurrent, short-term, and long-term effects of anodal tDCS over M1 on IMSL, as measured by the serial reaction time (SRT) task, in persons with PD with mild cognitive impairment (MCI). Concurrent (anodal/sham tDCS intervention during the SRT task), short-term (5 min post-intervention), and long-term (1 week post-intervention) effects on IMSL were evaluated in persons with idiopathic PD (Hoehn and Yahr stage II-III) with MCI. Results of 11 persons with PD (8 men and 3 women; mean age = 77.1 years; mean disease duration = 7.7 years) showed significant IMSL in the anodal (p = .016), but not in the sham tDCS condition (p = .937). Post-hoc analyses showed that IMSL reached statistical significance at 1 week post-intervention (p < .001). Anodal tDCS over M1 exerted beneficial effects on IMSL in persons with PD with MCI, in particular one week post-intervention. Our study is the first to report a positive effect of tDCS on IMSL in PD. Further research should include a larger, more cognitively diverse sample and additional follow-up periods.     

Rate of Torque Development and Feedforward Control of the Hip and Knee Extensors: Gender Differences

The purpose of this study was to determine whether women demonstrate decreased rate of torque development (RTD) of the hip and knee extensors and altered onset timing of the vastus lateralis and gluteus maximus during a drop-jump task when compared with men. On average, women demonstrated significantly lower normalized RTD of the hip extensors (women: 11.6 ± 1.3 MVT.s^?1, men: 13.1 ± 0.9 MVT.s^?1; p ≤ .01); however, there was no significant difference in knee extensor RTD. Women also demonstrated significantly earlier activation of their vastus lateralis (women: 206.0 ± 130.6 ms, men: 80.9 ± 69.6 ms; p ≤ .01) and gluteus maximus (women: 85.7 ± 58.6 ms, men: 54.5 ± 35.4 ms; p = .02). In both men and women, there was a significant negative correlation between the hip extensor RTD and the vastus lateralis electromyographic onset time (men: r = –.386, p = .046; women: r = –.531, p = .008). The study findings suggest that women may utilize a feedforward control strategy in which they activate their knee extensors earlier than men to compensate for deficits in hip extensor RTD. The impaired capacity to rapidly stabilize the hip and knee joints during dynamic maneuvers may contribute to the increased risk of anterior cruciate ligament injury observed in women.     

Investigating the influence of an effort–reward interaction on cognitive fatigue in individuals with multiple sclerosis

This study examined whether an alteration in the effort–reward relationship, a theoretical framework based on cognitive neuroscience, could explain cognitive fatigue. Forty persons with MS and 40 healthy age- and education-matched cognitively healthy controls (HC) participated in a computerized switching task with orthogonal high- and low-demand (effort) and reward manipulations. We used the Visual Analog Scale of Fatigue (VAS-F) to assess subjective state fatigue before and after each condition during the task. We used mixed-effects models to estimate the association and interaction between effort and reward and their relationship to subjective fatigue and task performance. We found the high-demand condition was associated with increased VAS-F scores (p < .001), longer response times (RT) (p < .001) and lower accuracy (p < .001). The high-reward condition was associated with faster RT (p = .006) and higher accuracy (p = .03). There was no interaction effect between effort and reward on VAS-F scores or performance. Participants with MS reported higher VAS-F scores (p = .02). Across all conditions, participants with MS were slower (p < .001) and slower as a function of condition demand compared with HC (p < .001). This behavioural study did not find evidence that an effort–reward interaction is associated with cognitive fatigue. However, our findings support the role of effort in subjective cognitive fatigue and both effort and reward on task performance. In future studies, more salient reward manipulations could be necessary to identify effort–reward interactions on subjective cognitive fatigue.     

Preference for attractiveness and thinness in a partner: Influence of internalization of the thin ideal and shape/weight dissatisfaction in heterosexual women, heterosexual men, lesbians, and gay men

This study assesses whether characteristics of one's own body image influences preferences of attractiveness in a partner. The role of gender and sexual orientation is also considered. Heterosexual women (n = 67), lesbian women (n = 73), heterosexual men (n = 61) and gay men (n = 82) participated in an internet survey assessing attitudes towards the body and preferences of attractiveness in a partner. Men in particular were found to prefer attractive partners, regardless of sexual orientation. Weight/shape dissatisfaction was found to be a negative predictor for heterosexual men and women. For gay men, preferences were better explained by internalization and weight/shape dissatisfaction. No such associations were found in the lesbian group. Levels of weight/shape dissatisfaction and internalization of socio-cultural slenderness ideals influence expectations of thinness and attractiveness in a partner with this effect being modified by gender and sexual orientation.     

False memory,attentional bias and future thinking among people living with HIV with posttraumatic stress disorder

People living with HIV can experience posttraumatic stress disorder (PTSD). Complex relationships exist between HIV, PTSD and cognitive impairments. This cross-sectional study compared three cognitive impairments (false memory, attentional bias, deficits in future thinking) among people living with HIV with and without PTSD in Iran. People living with HIV with PTSD (n = 20) and without PTSD (n = 20) completed measures of psychological symptomatology, dot-probe task, Deese Roediger McDermott paradigm and future thinking task at Razavi Khorasan Health Center. The PTSD group, when compared to the non-PTSD group, recognised a significantly greater number of false memories (p < .001; η² = .58), had an attentional bias toward threat-related words (p < .001; η² = .35) and imagined fewer specific future events (p < .001; η² = .31). People living with HIV with PTSD may have difficulties with false memory, attentional biases, and generating future events. Since psychological treatments are limited in Iran, this research highlighted some potential cognitive targets for people living with HIV.     

The cerebellum and language: Evidence from patients with cerebellar degeneration

Clinical and imaging studies suggest that the cerebellum is involved in language tasks, but the extent to which slowed language production in cerebellar patients contributes to their poor performance on these tasks is not clear. We explored this relationship in 18 patients with cerebellar degeneration and 16 healthy controls who completed measures of verbal fluency (phonemic and semantic), word stem completion, and oral naming speed. Cerebellar patients showed significantly slower response times when naming common nouns, which correlated with their degree of motor impairment. Patients were significantly impaired on both phonemic and semantic fluency measures compared to controls (p < 0.001), even when naming speed was entered as a covariate (p = 0.03). On the word stem completion task, patients were significantly less accurate (p < 0.001), had more errors due to non-responses (p = 0.008), and were slower to respond (p = 0.036) than controls; group effects were significant for overall accuracy, but not response time, when the effects of naming speed were covaried (p = 0.014). These findings suggest that cerebellar patients’ poorer performance on language tasks cannot be explained solely by slower language production, and that the integrity of cerebellar-prefrontal loops might underlie poorer performance on measures of executive function in cerebellar patients.
