The impact of E-diaries and accelerometers on young adults' perceived and objectively assessed physical activity

ObjectiveE-diaries and accelerometers promise more objective, real-time measurements of health behavior. However, social-psychological theory suggests that using electronic behavioral monitoring may influence rather than just record physical activity (PA), especially when a device is novel.DesignParticipants (n = 146) were randomly assigned to either an accelerometer-only, e-diary-only, accelerometer + e-diary, or a no-technology control group for one week to assess how these technologies influenced PA, both perceived and actual, in young adults.MethodParticipants reported their PA, overall and number of discrete exercise sessions (DES) at baseline and follow-up; accelerometers provided daily step counts and e-diaries captured daily reports of PA for the active week of the study.ResultsAverage daily steps in the accelerometer-only and accelerometer + e-diary groups did not differ nor did daily reports of PA via e-diary compared to accelerometer + e-diary group, showing that neither technology affected actual PA. ANCOVAS tested group differences in perceived PA; The accelerometer-only group had increased perceived overall PA but not DES compared to no-technology control.ConclusionsAccelerometers may increase perceived overall PA, but the tested technologies did not increase DES or actual PA, suggesting that they may be viable unbiased measures of PA.     

The quiet eye supports error recovery in golf putting

ObjectivesThe aim of this study was to further examine the relationship between the Quiet eye (QE, Vickers, 1996) and performance. We aimed to scrutinise the relationship between QE and shot outcome and replicate the robust relationship between QE and expertise. Based on recent findings (Cooke et al., 2015) showing that motor planning is dependent upon the outcome of a previous attempt, we wanted to examine the influence of prior performance on the functionality of the QE. Design: We performed a 2 (expertise) x 2 (outcome) mixed design study. Participants performed golf putts until they had achieved 5 successful (hits) and 5 unsuccessful (misses) attempts.Methods18 experienced and 21 novice golfers participated in the study. Putts were taken from ten feet while wearing a mobile eye tracker.ResultsExperienced golfers had consistently longer QE durations than novices but there was no difference in QE between randomly chosen hits and misses. However, QE durations were significantly longer on hits directly following a miss, but significantly shorter on misses following a miss.ConclusionsThis is the first study to have examined QE duration as a consequence of prior performance. Our findings highlight the important role of QE in recovering from an error and improving performance. The findings add further support for the response programming function of the QE, as additional ‘programming’ was needed to recover from an error. Findings also highlight the potential for a link between QE and the allocation of attentional resources to the task (effort).     

The role of pain behaviour and family caregiver responses in the link between pain catastrophising and pain intensity: A moderated mediation model

Objectives: This study investigated the mediating role of pain behaviours in the association between pain catastrophising and pain intensity and explored the moderating role of family caregivers’ responses to pain in the link between pain behaviours and pain intensity.

Methods: The sample consisted of 154 chronic pain patients and their family caregivers. Patients completed questionnaires regarding pain intensity, pain catastrophising, pain behaviours and their caregivers’ responses to their pain. Family caregivers reported their responses to the patients’ pain.

Results: Pain catastrophising was associated with pain intensity (r = 0.37) and pain behaviours partly mediated this association. The positive association between pain behaviours and pain intensity was significant only if patients reported that their family caregivers showed high levels of solicitous (effect = .49) and distracting responses (effect = .58), and if caregivers reported to show high levels of solicitous responses (effect = .51). No support was found for negative responses as a moderator neither based on patients’ perception of negative responses nor based on caregivers’ perception of negative responses.

Conclusions: The findings are in line with the idea that family caregivers’ solicitous and distracting responses convey to patients that their condition is serious, which may reinforce patients’ pain and pain behaviours, especially in those who catastrophise.

移情在道德强度对企业道德决策影响中的作用

摘 要 本研究将一种重要的道德情绪--移情引入问题权变模型中,以探讨移情因素在道德强度对企业道德决策影响中的作用。本研究基于情景研究法,随机选取256名MBA学生为被试,要求被试基于所提供情景中假想参与者的行为,回答随后测量道德决策(道德识别、道德判断和道德意图)、移情反应、主观道德强度及移情特质的问题。结果发现,1）移情反应在道德强度对企业道德决策的影响中具有中介作用;2）移情关怀特质会通过影响主观道德强度和移情反应而作用于企业道德决策;3)结果大小、社会舆论和效应可能性对道德判断和道德意图的影响机制各有特点。     

Intra-group aggression among prisoners: bullying intensity and exploration of victim-perpetrator mutuality

A new multiple indicator method of assessing bullying behaviour is employed (Direct and Indirect Prisoner behaviour Checklist - Scaled version [DIPC-SCALED]) with 605 adult prisoners (487 men and 118 women). The study explores if the DIPC-SCALED is a reliable method comprising of identifiable aggression factors; if prisoners can be classified into groups based on behavioural frequency; and if there is evidence for mutual victim/perpetrator groups. The DIPC-SCALED proved reliable, comprising of a number of aggression factors. Prisoners could be classified into groups based on behavioural frequency with one-fifth classified into an "intense" perpetrator and/or victim group. Evidence for mutual perpetrator/victims was found. Results are discussed with regards to the method used and the value in accounting for behavioural frequency in group classification.

Trait affect and job search outcomes

The present study examines the role of trait affect in job search. One hundred and twenty-three university students completed measures of positive and negative affectivity, conscientiousness, job search self-efficacy, job search clarity, and job search intensity during their last year of school while on the job market. At the end of the school year, participants completed the measure of job search intensity again, and indicated the number of interviews and offers they had received and whether they had accepted a full-time job. As hypothesized, positive affectivity predicted job search clarity over and above conscientiousness and job search self-efficacy. Job search clarity mediated relationships between positive affectivity and job search intensity and between job search self-efficacy and job search intensity. Negative affectivity, however, did not predict job search clarity. Job search clarity predicted job search intensity, which led to interviews, offers, and employment. The results suggest that job seekers high in positive affectivity find a job because they achieve job search clarity and, in turn, look for a job intensely.     

Dysphoria and Mobilization of Mental Effort: Effects on Cardiovascular Reactivity

Two studies examined the influence of dysphoria on motivational intensity in a student sample. Participants worked on a memory task (Study 1) or a mental concentration task (Study 2) without fixed performance standard (“do your best”). Based on their scores on the Center for Epidemiologic Studies – Depression Scale (L. S. Radloff, 1977), dysphoric and nondysphoric students were compared with regard to their effort-related cardiovascular reactivity during task performance. As predicted on the basis of the mood-behavior-model (G. H. E. Gendolla, 2000) and motivational intensity theory (J. W. Brehm & E. A. Self, 1989), dysphoric participants showed stronger cardiovascular reactivity while working on the cognitive tasks than nondysphoric participants. In Study 1, nondysphoric participants performed better on the memory task than dysphoric participants. Theoretical implications are discussed.

Heart-rate deceleration and smiling in 3-month-old infants

The relation between heart-rate deceleration and the expression of positive affect in infancy is examined by testing the hypothesis that intensity of orienting (as indexed by heart-rate deceleration) is predictive of intensity of positive affect (smile size and duration). A social-stimulation procedure was utilized to elicit smiles in 41 3-month-old infants. The first smile elicited was coded for smile size and duration, and the preceding heart-rate deceleration was coded for magnitude, duration, and slope of deceleration. Slope and duration of heart-rate deceleration proved to be reliable predictors of smile size, but none of the heart-rate measures correlated with smile duration. Results suggest that the steeper and more rapid the deceleration, the larger the ensuing smile. Possible mechanisms for this finding are discussed.
