Very little is known about the cognitive functioning of people with body-focused repetitive behaviours and the few existing studies provide mixed findings. The aim of this study was to investigate the interplay between attentional control, negative affectivity, and focused skin picking. We hypothesized that the control of attention is associated with focused style of skin picking and that this relationship is moderated by negative affectivity. The final sample consisted of 273 non-clinical subjects (79% women) aged 18 to 54 years; study variables were assessed using questionnaires. Moderation analysis was conducted, followed by a simple slope analysis, and the Johnson-Neyman technique was used to probe the interaction effect. We found that at the low level of negative affectivity, the relationship between attentional control and focused skin picking is negative, but not at the higher levels of this trait. Interestingly, when negative affectivity reaches very high intensity, the association between attentional control and skin picking becomes positive. This relationship seems to be quite complex and may depend on the way that cognitive abilities are used by the individual, as well as on the stage of cognitive processing that they are applied to. Further studies using behavioural measures of attention are needed to better understand this issue.

Valence and salience encoding in the central amygdala.

The central amygdala (CeA) has emerged as an important brain region for regulating both negative (fear and anxiety) and positive (reward) affective behaviors. The CeA has been proposed to encode affective information in the form of valence (whether the stimulus is good or bad) or salience (how significant is the stimulus), but the extent to which these two types of stimulus representation occur in the CeA is not known. Here, we used single cell calcium imaging in mice during appetitive and aversive conditioning and found that majority of CeA neurons (~65%) encode the valence of the unconditioned stimulus (US) with a smaller subset of cells (~15%) encoding the salience of the US.

Background: A happy adolescent may live a healthy and successful life. This study focused on parental expectations in the Chinese cultural context and investigated whether and under what conditions adolescents' perceived parental expectations are associated with their happiness, the affective component of subjective well-being.
Sample And Methods: This cross-sectional study included a sample of 1510 Chinese adolescents; the average age of the adolescents was 12.
Does habit strength moderate affective responses to movement-related behaviors among older adults?

Physical activity (PA) and sedentary behavior (SB) are associated with affective feeling states in older adults, though the strength and direction of associations vary. This study used the Ecological Momentary Assessment (EMA) to determine how habit strength affects affective responses to movement behaviors. Older adults completed a 4-day EMA protocol with 10 randomly delivered, smartphone assessments per day while simultaneously wearing two activity monitors recording PA and SB.

Objective: This exploratory prospective cohort study aimed to investigate the trajectory of psychological distress and posttraumatic growth (PTG) in rectal cancer patients from diagnosis to follow-up and to explore factors that could predict PTG and psychological distress at follow-up.
Method: We assessed psychological distress (anxiety and depression), PTG, physical symptoms, quality of life, cancer-related coping, state and trait affectivity, resilience, and alexithymia in 43 rectal cancer patients, ) age: 61.6 (12.
Within-person affect dynamics among individuals in residential treatment for opioid use disorder: An ecological momentary assessment study.

Ecological momentary assessment is increasingly leveraged to better understand affective processes underlying substance use disorder treatment and recovery. Research in this area has yielded novel insights into the roles of mean levels of positive affect (PA) and negative affect (NA) in precipitating drug craving and substance use in daily life. Little of the extant substance use disorder treatment research, however, considers dynamic patterns of PA and NA, separately or in relation to one another, or how such patterns may differ from those observed among nonclinical samples.
