Emotion regulation difficulties in anorexia nervosa: Relationship to self-perceived sensory sensitivity

Changes in sensation (e.g., prickly skin) are crucial constituents of emotional experience, and the intensity of perceived changes has been linked to emotional intensity and dysregulation. The current study examined the relationship between sensory sensitivity and emotion regulation among adults with anorexia nervosa (AN), a disorder characterised by disturbance in the experience of the body. Twenty-one individuals with AN, 20 individuals with AN who were weight–restored, and 23 typical controls completed self-report measures of sensory sensitivity and emotion regulation. AN participants reported heightened sensory sensitivity and greater difficulty regulating emotions relative to controls. Self-perceived sensory sensitivity was associated with greater emotion dysregulation. Weight-restored AN participants reported greater ability to regulate emotions than their currently underweight counterparts, despite heightened sensitivity. Findings suggest that hypersensitivity may be a persisting feature in AN, and that weight restoration may involve improved ability to cope with sensation.     

Comparison of Rorschach anatomy responses from psychosomatic out-patients and a matched group of psychiatric controls.

35 out-patient Ss with demonstrable psychosomatic symptoms were matched with 35 psychiatric out-patients with "milder" forms of psychopathology, i.e., neurosis, personality disorders and latent schizophrenia. The psychosomatic group showed significantly more anatomy responses on the Rorschach but there was much overlap, leading to the conclusion that anatomy does not directly reflect simply psychosomatic disturbances but, rather, is associated with psychodynamics which tend to underlie psychosomatic illnesses.     

Parameters of digitally averaged potentials of individual motor units]

Of sixty normal subjects of different age six different muscles each were examined electromyographically. The activity pattern was recorded for moderate voluntary innervation and superposed digitally. The parameters of digitally averaged summation action potentials were compared with those of manually assessed potentials. The two methods gave identical results: The duration of potentials was between 5 and 10 ms. It increased in the younger and older age groups and showed only slight changes in middle-aged persons. Only minor differences were found between the muscles of one age group, an exception being the orbicularis oris muscle. The results obtained are compared with values reported in the literature.     

Effects of cooperation and competition on responsibility attribution after success and failure

Pairs of Ss cooperated (Experiment I) or competed (Experiment II) in a response-matching task whose outcome either exceeded (Success condition), met (Neutral condition), or did not reach (Failure condition) a prior-established expected outcome level. Afterwards, Ss attributed responsibility for their outcomes. It was found under both cooperation and competition that neutral outcomes tended to produce situational attribution, and success produced self-attribution. However, failure produced partner attribution under cooperation but situational attribution under competition. The results were discussed from the standpoint of two general theories of responsibility attribution, the first emphasizing problem solving based on cues, and the second emphasizing motivational biases.     

The tonic immobility reaction in chickens: Response characteristics and methodology

A total of 379 chickens were run in five studies to assess the effect of different procedures on tonic immobility and to measure some of the response components of the reaction. The optimal period of manual restraint, by way of producing the most durable immobility response, was found to be 15 sec, and pretest holding conditions were shown to exert a significant influence on the reaction in naive birds. Birds who defecated during immobility or shortly after termination, remained immobile longer than comparable nondefecators. Duration of eye closure and latency of vocalization were also found to be good predictors of the duration of an immobility episode.     

Positive Feelings at School: On the Relationships Between Students’ Character Strengths,School-Related Affect,and School Functioning

The present study was designed to examine the relationships between students’ character strengths, school-related affect, positive school functioning (i.e., motivation to learn, interest, and engagement at class), and school achievement following the “engine model of well-being” that is focusing on inputs (e.g., personality traits), processes (e.g., moods, emotions), and outcomes (e.g., engagement, accomplishments) within the context of well-being research. A sample of 196 children completed the Values in Action Inventory of Strengths for Youth, which assesses 24 character strengths, and the PANAS-C that assesses school-related positive and negative affect. Additionally, homeroom teachers rated students’ positive school functioning (i.e., motivation, engagement, and interest at school) and their overall school achievement. The character strengths of zest, love of learning, perseverance, and social intelligence showed the strongest positive correlations with school-related positive affect. Teamwork, hope, self-regulation, and love were substantially negatively correlated with school-related negative affect. Certain character strengths showed positive relationships with positive school functioning and overall school achievement. A path model, testing the “engine model of well-being”, found—additionally to direct effects—indirect relationships between character strengths and positive school functioning (through school-related positive affect), which in turn leads to higher school achievement. The presented findings show character strengths as meaningful resources in the schooling context. Character strengths emerge to be crucial for students to experience school-related positive affect, which in turn supports students’ positive school functioning and their overall school achievement. The results demonstrate the complex interplay between students’ personality traits, affect, school functioning, and achievement at school.     

The Role of Non-Numerical Stimulus Features in Approximate Number System Training in Preschoolers from Low-Income Homes

Recent findings have suggested that adults’ and children’s approximate number system (ANS) acuity may be malleable through training, but research on ANS acuity has largely been conducted with adults and children who are from middle- to high-income homes. We conducted 2 experiments to test the malleability of ANS acuity in preschool-aged children from low-income homes and to test how non-numerical stimulus features affected performance. In Experiment 1, mixed-effects models indicated that children significantly improved their ratio achieved across training. Children’s change in probability of responding correctly across sessions was qualified by an interaction with surface area features of the arrays such that children improved their probability of answering correctly across sessions on trials in which numerosity conflicted with the total surface area of object sets significantly more than on trials in which total surface area positively correlated with numerosity. In Experiment 2, we found that children who completed ANS acuity training performed better on an ANS acuity task compared with children in a control group, but they only did so on ANS acuity trials in which numerosity conflicted with the total surface area of object sets. These findings suggest that training affects ANS acuity in children from low-income homes by fostering an ability to focus on numerosity in the face of conflicting non-numerical stimulus features.
