A novel continuous inhibitory-control task: variation in individual performance by young pheasants (<Emphasis Type="Italic">Phasianus colchicus</Emphasis>)

Inhibitory control enables subjects to quickly react to unexpectedly changing external demands. We assessed the ability of young (8 weeks old) pheasants Phasianus colchicus to exert inhibitory control in a novel response-inhibition task that required subjects to adjust their movement in space in pursuit of a reward across changing target locations. The difference in latencies between trials in which the target location did and did not change, the distance travelled towards the initially indicated location after a change occurred, and the change-signal reaction time provided a consistent measure that could be indicative of a pheasant’s inhibitory control. Between individuals, there was a great variability in these measures; these differences were not correlated with motivation either to access the reward or participate in the test. However, individuals that were slower to reach rewards in trials when the target did not change exhibited evidence of stronger inhibitory control, as did males and small individuals. This novel test paradigm offers a potential assay of inhibitory control that utilises a natural feature of an animal’s behavioural repertoire, likely common to a wide range of species, specifically their ability to rapidly alter their trajectory when reward locations switch.     

Mindfulness reduces the correspondence bias

The correspondence bias (CB) refers to the idea that people sometimes give undue weight to dispositional rather than situational factors when explaining behaviours and attitudes. Three experiments examined whether mindfulness, a non-judgmental focus on the present moment, could reduce the CB. Participants engaged in a brief mindfulness exercise (the raisin task), a control task, or an attention to detail task before completing a typical CB measure involving an attitude-attribution paradigm. The results indicated that participants in the mindfulness condition experienced a significant reduction in the CB compared to participants in the control or attention to detail conditions. These results suggest that mindfulness training can play a unique role in reducing social biases related to person perception.     

Motor sequence learning performance in Parkinson's disease patients depends on the stage of disease

It is still unclear, whether patients with Parkinson's disease (PD) are impaired in the incidental learning of different motor sequences in short succession, although such a deficit might greatly impact their daily life. The aim of this study was thus to clarify the relation between disease parameters of PD and incidental motor learning of two different sequences in short succession. Results revealed that the PD patients were able to acquire two sequences in short succession but needed more time than healthy subjects. However, both the severity of axial manifestations, as assessed on a subsection of the Unified Parkinson's Disease Rating Scale III (UPDRS III) and the Hoehn and Yahr score, and the levodopa-equivalent dose (LED) were negatively correlated with the sequence learning performance. These findings indicate that, although PD patients are able to learn two sequences in short succession, they need more time and their overall sequence learning performance is strongly correlated with the stage of disease.     

Client attendance measures in counselling psychology trainees

Counselling supervisors and educators have yet to reach a consensus about standard measures for evaluating the performance of graduate student therapists. Compared to self‐reports and rater judgements, client attendance records provide low‐inference behavioural data partially reflective of clients’ engagement with therapists. This naturalistic study evaluates client attendance data using archival records of 92 doctoral students in beginning and advanced counselling practica who produced data for 771 clients, 3,949 scheduled sessions and 3,186 attended sessions. Providing evidence of the sample representativeness for clinicians, results indicated that the mean number of sessions attended per client for student therapists (5.65) was very similar to that reported in the literature for outpatient therapists (<6). As expected because of structural differences in client assignment, beginning and advanced students evidenced statistically significant differences on attendance variables such as number of clients and scheduled sessions. In contrast, attendance ratios were equivalent across counsellor experience, suggesting that these individual difference variables could be useful for evaluation of therapist competencies related to client engagement.     

Walking versus biofeedback: a comparison of acute interventions for stressed students

Background: High rates of stress-related problems in college students and low utilization of treatment options demonstrate the need for effective stress-reducing interventions that can be self-regulated. This study compared the effect of brief paced-breathing with biofeedback and exercise interventions on heart rate variability, state anxiety and affect. Methods: Students (n?=?32) with high levels of perceived stress completed three 10-min interventions on separate days: paced-breathing with biofeedback (Biofeedback), a self-paced walk (Exercise), and an attention control condition of quiet studying (Quiet Study). Anxiety and affect were measured before (Pre), immediately after (Post0) and 15 mins after (Post15) the intervention. Heart rate variability was measured pre- and post-intervention using electrocardiogram. Results: Biofeedback reduced anxiety more than the exercise condition (Pre to Post0: Biofeedback d?=??0.48, Exercise d?=??0.13). Secondly, Exercise temporarily increased energy (Pre to Post0: d?=?0.67), whereas Biofeedback temporarily increased calmness (Pre to Post0: d?=?0.51). All conditions significantly increased total heart rate variability (p?Conclusions: Biofeedback and Exercise interventions improved emotional states in high-stress college students, but the type of change observed (i.e. energizing, calming or anxiety reducing) depended upon the condition.     

Believing in a personal just world helps maintain well-being at work by coloring organizational justice perceptions

Justice is a core fundamental theme for individuals in organizations. This study suggests that believing the world is just where one gets what one deserves, and deserves what one gets, is an important personal resource that helps maintain well-being at work. Further, it suggests that personal belief in a just world, but not general belief in a just world, exerts its influence on well-being through increasing overall justice perceptions of the work environment. Using two waves of data drawn from a large random sample of working adults in Switzerland, results showed that personal belief in a just world at time 1 indeed augmented perceptions of overall organizational justice, and this in turn increased job satisfaction at time 2, that is, 1 year later. As expected, this effect was only evident for personal and not general belief in a just world, highlighting personal belief in a just world as an important yet largely overlooked resource for the work context, and suggesting the need to consider individual’s beliefs about justice as drivers of overall organizational justice perceptions.     

Things are sounding up: Affective influences on auditory tone perception

Recent studies have documented robust and intriguing associations between affect and performance in cognitive tasks. The present two experiments sought to extend this line of work with reference to potential cross-modal effects. Specifically, the present studies examined whether word evaluations would bias subsequent judgments of low- and high-pitch tones. Because affective metaphors and related associations consistently indicate that positive is high and negative is low, we predicted and found that positive evaluations biased tone judgment in the direction of high-pitch tones, whereas the opposite was true of negative evaluations. Effects were found on accuracy rates, response biases, and reaction times. These effects occurred despite the irrelevance of prime evaluations to the tone judgment task. In addition to clarifying the nature of these cross-modal associations, the present results further the idea that affective evaluations exert large effects on perceptual judgments related to verticality.
