Throwing more light on the dark side of psychopathy: An extension of previous findings for the revised Reinforcement Sensitivity Theory

Despite previous studies of psychopathy and the motivational systems of the Reinforcement Sensitivity Theory (RST) of personality, few have examined psychopathy in light of the revised RST model. In a large sample (N = 779) of young adults, we expand on Hughes, Moore, Morris, and Corr’s (2012) preliminary findings relating primary/secondary psychopathy to revised RST’s three systems: Flight-Flight-Freeze System (FFFS), Behavioral Inhibition System (BIS), and Behavioral Approach System (BAS). Converging results between Hughes et al. and the current study emphasize three major findings: (1) primary psychopathy is negatively related to the BIS as well as the FFFS; (2) primary psychopathy is positively related to goal-driven behavior of the BAS; and, (3) secondary psychopathy is positively related to impulsivity reflected in the BAS. The FFFS was incrementally predictive of primary but not secondary psychopathy. No evidence for a BAS × BIS interaction in psychopathy was found. Results are discussed in terms of future research directions.     

Decoding facial blends of emotion: Visual field,attentional and hemispheric biases

Most clinical research assumes that modulation of facial expressions is lateralized predominantly across the right-left hemiface. However, social psychological research suggests that facial expressions are organized predominantly across the upper-lower face. Because humans learn to cognitively control facial expression for social purposes, the lower face may display a false emotion, typically a smile, to enable approach behavior. In contrast, the upper face may leak a person’s true feeling state by producing a brief facial blend of emotion, i.e. a different emotion on the upper versus lower face. Previous studies from our laboratory have shown that upper facial emotions are processed preferentially by the right hemisphere under conditions of directed attention if facial blends of emotion are presented tachistoscopically to the mid left and right visual fields. This paper explores how facial blends are processed within the four visual quadrants. The results, combined with our previous research, demonstrate that lower more so than upper facial emotions are perceived best when presented to the viewer’s left and right visual fields just above the horizontal axis. Upper facial emotions are perceived best when presented to the viewer’s left visual field just above the horizontal axis under conditions of directed attention. Thus, by gazing at a person’s left ear, which also avoids the social stigma of eye-to-eye contact, one’s ability to decode facial expressions should be enhanced.

Testing the Physical Activity Self-Definition Model among low-active adults participating in a physical activity intervention

Seeing oneself as a physically active person is one of the strongest predictors of physical activity behaviour and self-regulatory strategies. Determining whether and how physical activity self-perceptions can be stimulated may help low-active individuals who do not see themselves as a physically active person become more active. Cross-sectional research has tested the Physical Activity Self-Definition (PASD) model among active samples; longitudinal studies among low-active adults have yet to be done. The purpose of this study was to test the predictive power of the PASD model among low-active adults over a 16-week physical activity intervention. Participants completed surveys of validated questionnaires in-person at baseline (pre-intervention) and at 16-weeks (end of intervention) at one of two primary care facilities. The final sample included 119 low-active adults. Partial least squares-structural equation modeling indicated that the original model had small-medium predictive power (Q² = 0.22; SRMR = 0.13 [0.05, 0.07]; RMSE = 1.13; MAE = 0.9; BIC = 1348.40). Two paths were added in the revised model (perceived wanting—PASD; perceived ability—perceived commitment), which explained an additional 4% and 5% of the variance in perceived commitment (R² = 0.62 [0.48, 0.72]) and PASD (R² = 0.74 [0.64, 0.80]; all p’s < 0.001), respectively. The revised model had medium predictive power (Q² = 0.25; SRMR = 0.11 [0.05, 0.06]; RMSE = 1.1; MAE = 0.87; BIC = 1332.84) All path coefficients remained positive and significant at p ≤ .001. Among low-active adults, perceived wanting and perceived ability may be more salient when engaging in physical activity and regarding themselves as a physically active person. Findings may support practitioners and health care professionals in designing physical activity interventions to foster PASD among low-active adult populations.     

Why is “blindsight” blind? A new perspective on primary visual cortex,recurrent activity and visual awareness

The neuropsychological phenomenon of blindsight has been taken to suggest that the primary visual cortex (V1) plays a unique role in visual awareness, and that extrastriate activation needs to be fed back to V1 in order for the content of that activation to be consciously perceived. The aim of this review is to evaluate this theoretical framework and to revisit its key tenets. Firstly, is blindsight truly a dissociation of awareness and visual detection? Secondly, is there sufficient evidence to rule out the possibility that the loss of awareness resulting from a V1 lesion simply reflects reduced extrastriate responsiveness, rather than a unique role of V1 in conscious experience? Evaluation of these arguments and the empirical evidence leads to the conclusion that the loss of phenomenal awareness in blindsight may not be due to feedback activity in V1 being the hallmark awareness. On the basis of existing literature, an alternative explanation of blindsight is proposed. In this view, visual awareness is a “global” cognitive function as its hallmark is the availability of information to a large number of perceptual and cognitive systems; this requires inter-areal long-range synchronous oscillatory activity. For these oscillations to arise, a specific temporal profile of neuronal activity is required, which is established through recurrent feedback activity involving V1 and the extrastriate cortex. When V1 is lesioned, the loss of recurrent activity prevents inter-areal networks on the basis of oscillatory activity. However, as limited amount of input can reach extrastriate cortex and some extrastriate neuronal selectivity is preserved, computations involving comparison of neural firing rates within a cortical area remain possible. This enables “local” read-out from specific brain regions, allowing for the detection and discrimination of basic visual attributes. Thus blindsight is blind due to lack of “global” long-range synchrony, and it functions via “local” neural readout from extrastriate areas.

The effects of patient's frequency of attendance and etiology of symptoms,on the General Practitioners wellbeing

IntroductionThe presence of Medically Unexplained Symptoms and a high Frequency of Attendance negatively affects the General Practitioners’ (GP) wellbeing. Although, overlapping between both phenomena is partial, with a number of frequent attenders reporting medically unexplained symptoms during consultation, there is no evidence on how GP's well-being it is affected by the specific main effects of these factors and their interaction. Evidence is also scant on the psychological processes explaining the negative impact of attendance and the etiology of symptoms on GP's wellbeing.ObjectiveDrawing on the Job Demand-Control and the Conservation of Resource stress models, this paper tests the moderating effects of the GP’ perception of patient's attendance and etiology of symptoms on the relationship between patient's demands and feedback on the GP's wellbeing.MethodA total of 105 volunteer GPs self-reported on the study variables through an experience sampling methodology after 898 patients’ consultation. Patients attendance and etiology of symptoms were categorized according to the physician self-perception and an external criterion (organizational records).ResultsPerception of Patients Frequent Attendance and Medically Unexplained Symptoms were positively related to physician's Emotional Exhaustion. Contrary to expected the test of the moderation effects of patients characteristics on the relation between patient's demands and feedback and the GP's emotional exhaustion were stronger for normal attenders compared with frequent attenders. An ad hoc study shows this unexplained result is related to the GP's expectations on Frequent vs. normal attenders’ behaviors. No significant results were found when the external criterion of classification was used.ConclusionCombined analysis of Frequency of Attendance and Etiology of Symptoms lead to a better understanding of the GP's decreased wellbeing. Also, the perception of the strain level (demands/positive feedback levels) associated to the consultation with different types of patients contribute to explain the consequences for the GP's wellbeing, especially when GP's expectations on patient's behaviors are violated.
