An electrophysiological dissociation of craving and stimulus-dependent attentional capture in smokers

It has been suggested that over the course of an addiction, addiction-related stimuli become highly salient in the environment, thereby capturing an addict’s attention. To assess these effects neurally in smokers, and how they interact with craving, we recorded electroencephalography (EEG) in two sessions: one in which participants had just smoked (non-craving), and one in which they had abstained from smoking for 3 h (craving). In both sessions, participants performed a visual-search task in which two colored squares were presented to the left and right of fixation, with one color being the target to which they should shift attention and discriminate the locations of two missing corners. Task-irrelevant images, both smoking-related and non-smoking-related, were embedded in both squares, enabling the shift of spatial attention to the target to be examined as a function of the addiction-related image being present or absent in the target, the distractor, or both. Behaviorally, participants were slower to respond to targets containing a smoking-related image. Furthermore, when the target contained a smoking-related image, the neural responses indicated that attention had been shifted less strongly to the target; when the distractor contained a smoking-related image, the shift of attention to the contralateral target was stronger. These effects occurred independently of craving and suggest that participants were actively avoiding the smoking-related images. Together, these results provide an electrophysiological dissociation between addiction-related visual-stimulus processing and the neural activity associated with craving.     

The effect of identical word pairs on people's metamemory judgments: What are the contributions of processing fluency and beliefs about memory?

Judgments of learning (JOLs) are higher for identical pairs (dog–dog) than for related pairs (dog–cat). This identical effect may be mediated (a) by processing fluency (i.e., identical pairs are processed faster than related pairs) or (b) by a belief that identical pairs are better remembered or (c) by both factors. In the present work, we assessed the contribution of both factors. We evaluated whether a measure of processing fluency (i.e., self-paced study) mediated the relationship between pair type and JOLs (Experiment 1) and attempted to disrupt processing fluency using an AlTeRnAtInG presentation format (Experiment 2). We also evaluated whether judgments made in the absence of processing fluency demonstrated the identical effect (Experiment 3), and, finally, we had participants read a vignette about an experiment that included both pair types and estimate which pairs would be best remembered (Experiment 4). Evidence from all experiments converged on the conclusion that people's beliefs about how variables affect memory—and not differential fluency—best explain the identical effect, although we cannot entirely rule out the possibility that fluency plays a small role. The outcomes were consistent with the analytic-processing theory of JOLs—namely, when instructed to make JOLs, people adopt an analytic problem-solving approach that involves identifying variation across pairs that plausibly relate to memory and then use this variation to make JOLs.     

Implicit theories of online trolling: Evidence that attention‐seeking conceptions are associated with increased psychological resilience

Three studies were conducted to investigate people's conceptions of online trolls, particularly conceptions associated with psychological resilience to trolling. In Study 1, a factor analysis of participants’ ratings of characteristics of online trolls found a replicable bifactor model of conceptions of online trolls, with a general factor of general conceptions towards online trolls being identified, but five group factors (attention‐conflict seeking, low self‐confidence, viciousness, uneducated, amusement) as most salient. In Study 2, participants evaluated hypothetical profiles of online trolling messages to establish the validity of the five factors. Three constructs (attention‐conflict seeking, viciousness, and uneducated) were actively employed when people considered profiles of online trolling scenarios. Study 3 introduced a 20‐item ‘Conceptions of Online Trolls scale’ to examine the extent to which the five group factors were associated with resilience to trolling. Results indicated that viewing online trolls as seeking conflict or attention was associated with a decrease in individuals’ negative affect around previous trolling incidents. Overall, the findings suggest that adopting an implicit theories approach can further our understanding and measurement of conceptions towards trolling through the identification of five salient factors, of which at least one factor may act as a resilience strategy.     

Engagement in Group Psychotherapy Among Marginalized Individuals With Hepatitis C

This article examines an innovative psychoeducational group model at a community-based hepatitis C treatment program in Toronto, Canada. Group support is increasingly used as part of community-based, interdisciplinary approaches to addressing the complex psychosocial needs and barriers to care of individuals living with and/or undergoing treatment for hepatitis C. This article articulates the theoretical framework and details of one such group model. It also examines group engagement and outcomes using data collected over three group cycles. Psychotherapeutic engagement was higher than might be anticipated for a highly marginalized population. Specifically, group cohesion measures were equivalent or higher compared to norms for other support/psychotherapy groups. This study suggests that individuals with complex psychosocial issues have the ability to engage meaningfully in group therapy.

Developing a treatment for hand‐clapping maintained by automatic reinforcement using sensory analysis,noncontingent reinforcement,and thinning

Two subjects diagnosed with autism spectrum disorder and related disabilities who engaged in hand‐clapping maintained by automatic reinforcement participated in this study. We conducted a sensory analysis to evaluate matched stimuli that functioned as an abolishing operation or extinction for different sources of sensory reinforcement. Finally, we implemented noncontingent reinforcement (NCR) using the stimuli found to compete in the assessment to reduce the target behavior, and we thinned item availability. Results showed a decrease in hand‐clapping, and hand‐clapping remained low when we thinned the schedule of reinforcement. This research further elucidates how NCR can treat problem behavior maintained by automatic reinforcement.
