Effect of personality dimensions on the diurnal pattern of motor activity

The effects of personality dimensions, age, and gender on 24-hour motor activity patterns were studied in 101 healthy subjects between 20-70 years. We measured motor activity by wrist-actigraphy and personality dimensions by the Tridimensional Personality Questionnaire (TPQ) of Cloninger. Random Regression Models were used to estimate the effects of personality dimensions, age, and gender on the diurnal pattern of motor activity. Harm Avoidance as well as Reward Dependence influenced the overall level of motor activity, independent of age and gender. Subjects high on Harm Avoidance showed lower activity levels than subjects low on Harm Avoidance, whereas subjects high on Reward Dependence had higher overall levels of motor activity than subjects low on Reward Dependence. Older subjects were found to be less active than younger subjects, but the activity level did not differ between males and females.     

The role of motion direction selective extrastriate regions in reading: a transcranial magnetic stimulation study

Why reading ability is correlated with motion processing ability is perplexing. Activity in motion direction processing regions (Area V5/MT+) was perturbed by means of repetitive transcranial magnetic stimulation (rTMS) to examine its effect on reading. A functional probe (significant shortening of the motion aftereffect) was used to identify Area V5/MT+. Right-handed participants (8 m, 8 f) received three 7.5 min blocks of rTMS, after which two phonological and one orthographic reading tasks were administered. Application of rTMS to Area V5/MT+ (as compared to a non-rTMS baseline) significantly decreased performance only during non-word naming. The pattern of naming errors and the absence of deficits on the second phonological task were not consistent with a role for Area V5/MT+ in phonological decoding. Instead, its role in reading may be limited to image stabilization and/or letter localization.     

Behavior analysis in college classrooms: A scoping review

We conducted a scoping review of interventions that have been implemented classroom-wide in college classroom settings. We searched nine behavior-analytic journals from 2000 through 2020. We identified 59 studies that met our inclusion criteria and organized them into 13 categories: acceptance and commitment therapy (n = 1), equivalence-based instruction (n = 1), SAFMEDS (n = 4), guided notes (n = 4), response cards (n = 5), group contingencies (n = 5), interteaching (n = 6), programmed instruction, PSI, computer-aided (CA)PSI (n = 7), contingency arrangements (n = 15), feedback (n = 4), online delivery techniques (n = 4), game study sessions (n = 2), and peer-generated examples (n = 1). The interventions have been used with undergraduate and graduate students across various course topics and modalities. Most interventions produced positive results, commonly assessed via quiz and exam scores. This review presents the scope of interventions, their characteristics, and recommendations for future research.     

Different aspects of anxiety as predictors of post-operative anxiety and physical complaints

Previous studies have suggested that pre-operative anxiety consists of different aspects each with its own specific influence on post-operative state. This study investigated the influence of different aspects of transient anxiety i.e. state anxiety, specific anxiety, tension, observed anxiety and the amount of thinking about surgery, on post-operative anxiety and physical complaints in 126 patients undergoing lumbar surgery. Results showed that pre-operative state anxiety, specific anxiety, tension and observed anxiety each contributed uniquely to the prediction of post-operative anxiety after control for age, sex and medical variables. Tension showed a negative contribution, indicating that, when the effects of other anxiety aspects were removed, patients with high tension showed less post-operative anxiety than patients with low tension. The three other anxiety variables showed a positive contribution. Regarding postoperative physical complaints, only specific anxiety showed a positive significant contribution to the prediction. Results will be discussed in relation to the adaptation to surgery and to Janis' theory that experiencing moderate levels of anxiety is beneficial for recovery.     

Neuropsychiatry of hypersexuality

Relatively few studies of the psychobiology of hypersexuality have been undertaken. Nevertheless, the literature does suggest the possibility of a neurobiology of hypersexuality. Three cases of hypersexual behavior are presented in the context of neuropsychiatric disorders, and the literature on this phenomenon is briefly reviewed. These case studies and the literature provide evidence that different brain systems may play a role in this disorder. Frontal lesions may be accompanied by disinhibition, including impulsive hypersexual response to external cues, while striatal lesions may be accompanied by repetitive triggering of internally generated response patterns. Temporal-limbic lesions may be accompanied by disturbances in sexual appetite itself, including change in the direction of sexual drive. These case studies demonstrate that a neurobiology of hypersexuality may prove of some heuristic value in the clinic. However, further research is required to consolidate the literature in this area.     

The influence of power and reason on young Maya children's endorsement of testimony

Two important parenting strategies are to impose one's power and to use reasoning. The effect of these strategies on children's evaluation of testimony has received very little attention. Using the epistemic vigilance framework, we predict that when the reasoning cue is strong enough it should overcome the power cue. We test this prediction in a population for which anthropological data suggest that power is the prominent strategy while reasoning is rarely relied on in the interactions with children. In Experiment 1, 4‐ to 6‐year‐old children from a traditional Maya population are shown to endorse the testimony supported by a strong argument over that supported by a weak argument. In Experiment 2, the same participants are shown to follow the testimony of a dominant over that of a subordinate. The participants are then shown to endorse the testimony of a subordinate who provides a strong argument over that of a dominant who provides either a weak argument (Experiment 3) or no argument (Experiment 4). Thus, when the power and reasoning cues conflict, reasoning completely trumps power.     

Changes in Anabolic and Catabolic Activity among Women Taking Part in an Alternative Labour Market Programme

Thirty-two female participants in a mobilising labour market programme offering temporary, alternative employment in Sweden were followed longitudinally for one year, including a six month post participation follow-up period. It can be hypothesised that an important aspect of the physiological effects of unemployment is a change in the balance between anabolic and catabolic activities in the body and that re-employment should lead to a shift towards anabolism. An earlier study of a smaller subset of the data, however, including both men and women, showed increased prolactin and decreased dehydroepiadrosterone sulphate (DHEA-s) levels, contrary to the initial hypothesis. In the present analysis, intended to elucidate these results, psychophysiological data were summarised in two indices, one connected with anabolism (made up of testosterone and DHEA-s) and one with catabolism (prolactin, gamma-glutamyl transferase, aspartate amino transferase, alpha levuline amino transferase, and body mass index). In addition, self-rated anxiety, depression, hopelessness and personal control were analysed. The results indicate that the effect of 'better' activities within the programme was a temporary increase in anabolism, possibly indicating lower stress levels, and the effect of 'worse' activities, on the one hand, a temporary decrease in the catabolic index, probably reflecting repressed alcohol consumption, and, on the other hand, impaired anabolism. There was also a general but transient decrease in depressiveness measured by the Hospital Anxiety and Depression Scale. The results seem to imply that it is difficult to achieve lasting effects through a relatively short participation in a mobilising programme.
