Endogenous attention modulates early selective attention in psychopathy: An ERP investigation

Psychopathic individuals are prone to act on urges without adequate consideration of future consequences or the rights of other individuals. One interpretation of this behavior is that it reflects abnormal selective attention (i.e., a failure to process information that is incongruent with their primary focus of attention; Hiatt, Schmitt, & Newman, Neuropsychology, 18, 50-59, 2004). Unfortunately, it is unclear whether this selective attention abnormality reflects top-down endogenous influences, such as the strength or specificity of attention focus (i.e., top-down set) apart from other, more exogenous (bottom-up), effects on attention. To explore this question, we used an early visual event-related potential (N2pc) in combination with a modified visual search task designed to assess the effect of early endogenous (i.e., top-down) attention on the processing of set-congruent information. The task was administered to a sample of 70 incarcerated adult males, who were assigned to high, intermediate, and low psychopathy groups using Hare’s Psychopathy Checklist-Revised (Hare, 2003). Based on the assumption that their failure to process set-incongruent information reflects the exaggerated effects of endogenous attention, we predicted that participants with high psychopathy scores would show an exaggerated N2pc response to set-congruent information. The results supported the hypothesis and provide novel electrophysiological evidence that psychopathy is associated with exaggerated endogenous attention effects during early stages of processing. Further research is needed to examine the implications of this finding for the well-established failure of psychopathic individuals to process set-incongruent information and inhibit inappropriate responses.     

Social Context and the Dynamics of Cooperative Choice

Recent work using decontextualized economic games suggests that cooperation is a dynamic decision‐making process: Automatic responses typically support cooperation on average, while deliberation leads to increased selfishness. Here, we performed two studies examining how these temporal effects generalize to games with richer social context cues. Study 1 found that time pressure increased cooperation to a similar extent in games played with in‐group members and out‐group members. Study 2 found that time pressure increased cooperation to a similar extent in games described as competitions and games described as collaborations. These results show that previous positive effects of time pressure on cooperation are not unique to neutrally framed games devoid of social context and are not driven by implicit assumptions of shared group membership or cooperative norms. In doing so, our findings provide further insight into the cognitive underpinnings of cooperative decision making. Copyright © 2014 John Wiley & Sons, Ltd.     

Leisure and Subjective Well-Being: A Model of Psychological Mechanisms as Mediating Factors

Leisure is a key life domain and a core ingredient for overall well-being. Yet, within positive psychology, its definition and the psychological pathways by which it evokes happiness are elusive (Diener and Biswas-Diener 2008). In this paper, we seek to address these issues by delineating leisure and presenting a conceptual framework linking leisure to subjective well-being (SWB). Leisure is defined as a multidimensional construct, encompassing both structural and subjective aspects. Respectively, it is the amount of activity/time spent outside of obligated work time and/or perceived engagement in leisure as subjectively defined. To explain the effects of leisure on SWB, a quantitative summary of theories from 363 research articles linking leisure and SWB was conducted. Based on our findings, we propose five core psychological mechanisms that leisure potentially triggers to promote leisure SWB: detachment-recovery, autonomy, mastery, meaning, and affiliation (DRAMMA). These psychological mechanisms promote leisure SWB which leads to enhanced global SWB through a bottom-up theory of SWB. We discuss how future research can use this conceptual model for understanding the interplay between leisure and SWB.     

Using multidimensional item response theory to evaluate how response styles impact measurement

Multidimensional item response theory (MIRT) models for response style (e.g., Bolt, Lu, & Kim, 2014, Psychological Methods, 19, 528; Falk & Cai, 2016, Psychological Methods, 21, 328) provide flexibility in accommodating various response styles, but often present difficulty in isolating the effects of response style(s) from the intended substantive trait(s). In the presence of such measurement limitations, we consider several ways in which MIRT models are nevertheless useful in lending insight into how response styles may interfere with measurement for a given test instrument. Such a study can also inform whether alternative design considerations (e.g., anchoring vignettes, self-report items of heterogeneous content) that seek to control for response style effects may be helpful. We illustrate several aspects of an MIRT approach using real and simulated analyses.     

Enhancing Capacity for Trauma‐informed Care in Child Welfare: Impact of a Statewide Systems Change Initiative

Youth involved in the child welfare system (CWS) are disproportionally impacted by the negative effects of exposure to trauma. While efforts to develop trauma‐informed CWSs are accelerating, little research is available about the effects of these efforts on system capacity to respond to the needs of youth exposed to trauma. No studies evaluate longer‐term effects of these efforts. In 2011, Connecticut implemented CONCEPT, a multi‐year initiative to enhance capacity of the state's CWS to provide trauma‐informed care. CONCEPT used a multi‐component approach including workforce development, deployment of trauma screening procedures, policy change, improved access to evidence‐based trauma‐focused treatments, and focused evaluation of program effects. Changes in system capacity to deliver trauma‐informed care were assessed using statewide stratified random samples of child welfare staff at three time points (Year 1: N = 223, Year 3: N = 231, Year 5: N = 188). Significant improvements across nearly all child welfare domains were observed during the first 3 years of implementation, demonstrating system‐wide improvements in capacity to provide trauma‐informed care. These gains were maintained through the final year of implementation, with continued improvements in ratings of collaboration between child welfare and behavioral health settings on trauma‐related issues observed. Responses documented familiarity with and involvement in many of the CONCEPT activities and initiatives. Staff reported greater familiarity with efforts to increase access to specific evidence‐based services (e.g., TF‐CBT) or to enhance trauma‐related policy and practice guidelines, but less familiarity with efforts to implement new practices (e.g., trauma screening) in various sectors. Staff also reflected on the contribution of these components to enhance system capacity for trauma‐informed care.     

Do emotion-induced blindness and the attentional blink share underlying mechanisms? An event-related potential study of emotionally-arousing words

When two targets are presented within approximately 500 ms of each other in the context of rapid serial visual presentation (RSVP), participants’ ability to report the second target is reduced compared to when the targets are presented further apart in time. This phenomenon is known as the attentional blink (AB). The AB is increased in magnitude when the first target is emotionally arousing. Emotionally arousing stimuli can also capture attention and create an AB-like effect even when these stimuli are presented as to-be-ignored distractor items in a single-target RSVP task. This phenomenon is known as emotion-induced blindness (EIB). The phenomenological similarity in the behavioral results associated with the AB with an emotional T1 and EIB suggest that these effects may result from similar underlying mechanisms – a hypothesis that we tested using event-related electrical brain potentials (ERPs). Behavioral results replicated those reported previously, demonstrating an enhanced AB following an emotionally arousing target and a clear EIB effect. In both paradigms highly arousing taboo/sexual words resulted in an increased early posterior negativity (EPN) component that has been suggested to represent early semantic activation and selection for further processing in working memory. In both paradigms taboo/sexual words also produced an increased late positive potential (LPP) component that has been suggested to represent consolidation of a stimulus in working memory. Therefore, ERP results provide evidence that the EIB and emotion-enhanced AB effects share a common underlying mechanism.     

The clinician in the university: Reflections on a South African psychoanalytically oriented doctoral programme

There is increasing interest, both internationally and in South Africa, in strengthening the relationship between psychoanalytic practice and research. This paper reports on a psychoanalytically oriented doctoral programme offered at the University of the Witwatersrand in South Africa. The programme is described in relation to the broader context of the historical relationship of psychoanalysis to the university as well as to the specific context of the history of psychoanalysis in South Africa. Key challenges of the programme, specifically concerning research tensions and methodological and theoretical tolerance, are subsequently explored. The way in which these challenges manifested within a group context illustrates their potential for conflict as well as productive debate. The paper reflects on how this specific programme illuminates and extends some of the broader debates in the field of psychoanalysis.
