Effort to reduce postural sway affects both cognitive and motor performances in individuals with Parkinson’s disease

ObjectivesTo assess the effects of voluntarily reducing postural sway on postural control and to determine the attention level needed to do so in healthy adults (n = 16, 65.9 ± 9.7) and persons with PD (n = 25, 65.8 ± 9.5 years). Tasks: quiet and still standing conditions with and without a category task. Cognitive performance, center of pressure (CoP) displacement variability (RMSCoP) and velocity (VCoP) were assessed in the anterior-posterior (AP) and medial-lateral (ML) directions.Controls showed larger RMSCoP (AP) and VCoP (AP and ML) during still versus quiet standing (p < 0.01), while the PD group demonstrated no changes. In the PD group, RMSCoP and VCoP (ML) increased in still standing when performed with the cognitive task (p < 0.05). In both groups, cognitive responses decreased in still standing (p < 0.05).In PD, attempting to reduce postural sway did not affect postural control under single task conditions, however ML CoP variability and velocity did increase as a dual task. In older adults, increased displacement and velocity in both AP and ML directions was observed during single, but not dual task conditions. Therefore standing still might not be an adequate postural strategy as it increases the attentional demand and affects motor performance, putting persons with PD at greater risk for falls.     

Clients’ experiences of dynamic interpersonal therapy (DIT): opportunities and challenges for brief,manualised psychodynamic therapy in the NHS

Dynamic interpersonal therapy (DIT) is a brief manualised psychodynamic intervention for depression. This is a first study exploring clients’ experiences of DIT specifically and brief, manualised psychodynamic psychotherapy (PP) in general. Interpretative phenomenological analysis was the methodology employed. Five participants completed a semi-structured interview, three weeks to ten months after completing DIT. The scores of pre- and post-therapy outcome measures of depression and anxiety were also available. Two emerging superordinate themes are presented here: (1) ‘The Distinct Features of DIT’, referring to how its therapeutic style and time limitations were experienced and (2) the ‘Impact of Therapy’, referring to perceived outcomes. While previous findings showed that therapist’s perceived limited activity in long-term PP was experienced as hindering/unhelpful, the perceived sense of direction in DIT appeared adequate to most participants. Secondly, the time limitations provoked complex responses. Reactions to the distinct elements of DIT are to be treated both as therapeutic opportunities and as challenges. Further, in line with psychoanalytic theory, most participants described relational changes that went beyond symptom relief and remained in progress after therapy ended. Intriguingly, there was no consistency between participants’ qualitative accounts of change and the scores of the outcome measures.     

A pilot study of women’s affective responses to common and uncommon forms of aerobic exercise

Objective: To test the extent to which participants exposed to an uncommon versus common exercise stimulus would result in more favourable affect at post-task.

Design: Experimental design. Participants (N = 120), American women aged 18–45 years, were randomly assigned to complete 30-min of either the uncommon (HOOP; n = 58) or common (WALK; n = 62) exercise stimulus.

Main outcome measures: Self-reported affect and intentions for future exercise were measured before and after the 30-min exercise bout.

Results: Analyses of covariance were run to compare post-task affect across the HOOP and WALK conditions. At post-task, participants assigned to HOOP reported more positively valenced affect, higher ratings of positive activated affect, lower ratings of negative deactivated affect, and stronger intentions for future aerobic exercise compared to participants assigned to WALK.

Conclusions: Participants who completed an uncommon bout of aerobic exercise (HOOP) reported more favourable affect post-exercise, as well as stronger intentions for future exercise, compared to participants who completed a common bout of aerobic exercise (WALK). Future work using a longitudinal design is needed to understand the relationships between familiarity with an exercise stimulus, affective responses to exercise, motivation for future exercise behaviour and exercise maintenance over time.     

Salespersons’ empathy as a missing link in the customer orientation–loyalty chain: an investigation of drivers and age differences as a contingency

Salespersons’ customer orientation has attracted considerable attention from practitioners and researchers. By distinguishing customer-oriented attitude from behavior, this study sheds light on customers’ perceptions of salespersons’ empathy, as a missing link between customer orientation and customer-related outcomes. Noting the increasing age diversity among salespersons and customers, this study also investigates whether age differences in salesperson–customer dyads moderate the relationships of salespersons’ customer-oriented attitude and behavior with customer outcomes. Finally, this study examines salespersons’ climate perceptions as antecedents of their customer-oriented attitudes. Results of multilevel modeling with data from 164 salespersons and 405 customers reveal that salesperson empathy, as perceived by customers, is an important facilitator of the customer orientation–satisfaction relationship. When there are large age differences, salespersons’ customer-oriented attitude becomes more important for making customers feel understood by salespersons. Regarding antecedents, salespersons’ customer-oriented attitude is influenced by their perceptions of team-member exchange and age-inclusive climate.

青少年父母、同伴依恋与社会适应性的关系

对519个初、高中生施测青少年父母同伴依恋量表(IPPA)、自尊(SES)、中学生社会适应性量表,以探讨青少年父母、同伴依恋的现状,以及它们和自尊、社会适应之间的关系.结果表明:(1)青少年总体依恋质量较高.同伴的依恋质量高于父母依恋质量.(2)青少年的父母依恋在性别上没有差异;女生的同伴依恋得分显著高于男生.父母依恋的发展呈先降后升的趋势,初一年级最高,初三年级最低;同伴依恋呈先升后降再升趋势,但未见显著差异.(3)父亲依恋对青少年的心理弹性预测力最强,母亲依恋对心理优势感预测力最强,同伴依恋对人际适应性预测力最强.这种影响通过自尊的部分中介作用而实现.     

Composite Deep Belief Network approach for enhanced Antepartum foetal electrocardiogram signal

Antepartum Foetal surveillance is the most vital epoch of investigation during the pregnancy period. This surveillance would provide an opening to plan and manage the Foetus during Intrapartum and Antepartum stages of pregnancy. Moreover, it will help to identify high risk Foetuses during pregnancies which are complicated by maternal health conditions like diabetes mellitus, intrauterine growth restriction, etc. The foetal electrocardiogram (fECG) signal can be detected in the course of pregnancy from the Antepartum stage. Generally, fECG signal analysis is not carried out for Foetal surveillance. Rather, the traditional methodologies like phonocardiogram, etc. are being utilized. The reason is the unavailability of an effective methodology for providing good quality fECG signal. The proposal of a hybrid tactic called Bayesian Deep Belief Network (BDBN) for fECG signal enhancement is presented in this article. The proposed BDBN technique involves Baye’s filtering methodology in amalgamation with Deep Belief Network. The Baye’s filtering was employed to eliminate undesired signal components. Deep learning (DL) technique was utilized with Deep belief network (DBN) to extract high quality fECG signal. The methodology resulted with good quality fECG signal which is indeed valuable for timely Physician analysis.     

Consciously monitored grasping is vulnerable to perceptual intrusions

The idea of functional differentiation between vision-for-action and vision-for-perception has been supported by evidence from different domains. According to this account, perception is based on consciously accessible, relative representations, whereas vision-for-action is performed in an analytic, automatic manner. Support for this idea comes from studies that showed that unlike perception, grasping movements are refractory to illusions and to Weber’s law. Yet, interactions between the systems may occur when an action is performed in a less automated fashion. To test this idea, we asked participants to monitor their fingers apertures in flight and to halt their movement for a short duration when they felt that their aperture reached a maximum amount. The results showed that movements in the monitored condition were biased by the Ponzo illusion and showed atypical adherence to Weber's law. These results show that action and perception are more likely to interact when movements are performed in a controlled manner.
