Memory of pain induced by physical exercise

The aim of this study was to assess the memory of pain induced by running a marathon and the factors that influence it. Sixty-two marathon runners participated in the study, which comprised two phases. Immediately after a participant had reached the finishing line of the marathon, they were asked to rate the intensity and the unpleasantness of their pain and the emotions they felt at that time. Either three or six months later they were asked again to rate the intensity and the unpleasantness of the same pain experience. Regardless of the length of recall delay, participants underestimated both recalled pain intensity and unpleasantness. The pain and negative affect reported at the time of the pain experience accounted for 24% of the total variance in predicting recalled pain intensity and 22% of the total variance in predicting recalled pain unpleasantness. Positive affect at the time of pain experience was not a significant predictor of both the recalled pain intensity and pain unpleasantness. It is concluded that pain induced by physical exercise is not remembered accurately and the pain and negative affect experienced influence recall. Further research is needed on the influence of positive affect on the memory of pain.     

Predicting Cognitive and Social Consequences of Emotional Episodes: The Contribution of Emotional Intensity, the Five Factor Model, and Alexithymia

Emotional events are followed by recurrent thoughts (rumination) and talking about the event (social sharing of emotion). Factors that can account for variations in these consequences were examined (emotional intensity, the Five Factor Model, and two factors of alexithymia). In two samples, participants reported the most negative emotional event of recent months and in one sample also reported the most positive one. Results indicated that emotional intensity predicted social sharing and rumination, while neuroticism was positively related to intrusive thoughts about negative events and extraversion to rumination and social sharing about positive events. Difficulty describing feelings was negatively related to social sharing for negative events and reduced fantasy to rumination for positive events.

Motivated but not engaged: The implicit achievement motive requires difficult or unclear task difficulty conditions to exert an impact on effort

Integrating the achievement motive literature and motivational intensity theory, we expected the implicit achievement motive (nAch) to directly determine effort mobilization when task difficulty is unclear. However, nAch should interact with task difficulty in determining effort mobilization when task difficulty is clear. Participants worked on an easy versus difficult memory task (Study 1) or a clear versus unclear arithmetic task (Study 2). We used the Picture-Story-Exercise to assess nAch and pre-ejection period (PEP) to operationalize effort. As predicted, PEP reactivity was strong in the difficult-high-nAch condition and in the unclear-high-nAch condition but low in the other three conditions. Supporting motivational intensity theory, our results showed that nAch requires difficult or unclear task conditions to exert a noticeable impact on effort.     

Facial attractiveness impressions precede trustworthiness inferences: lower detection thresholds and faster decision latencies

Prior research has found a relationship between perceived facial attractiveness and perceived personal trustworthiness. We examined the time course of attractiveness relative to trustworthiness evaluation of emotional and neutral faces. This served to explore whether attractiveness might be used as an easily accessible cue and a quick shortcut for judging trustworthiness. Detection thresholds and judgment latencies as a function of expressive intensity were measured. Significant correlations between attractiveness and trustworthiness consistently held for six emotional expressions at four intensities, and neutral faces. Importantly, perceived attractiveness preceded perceived trustworthiness, with lower detection thresholds and shorter decision latencies. This reveals a time course advantage for attractiveness, and suggests that earlier attractiveness impressions could bias trustworthiness inferences. A heuristic cognitive mechanism is hypothesised to ease processing demands by relying on simple and observable clues (attractiveness) as a substitute for more complex and not easily accessible information (trustworthiness).     

Negative affect varying in motivational intensity influences scope of memory

Emotions influence cognitive processes involved in memory. While some research has suggested that cognitive scope is determined by affective valence, recent models of emotion–cognition interactions suggest that motivational intensity, rather than valence, influences these processes. The present research was designed to clarify how negative affects differing in motivational intensity impact memory for centrally or peripherally presented information. Experiments 1 & 2 found that, relative to a neutral condition, high intensity negative affect (anger) enhances memory for centrally presented information. Experiment 3 replicated this effect using another high intensity negative affect (threat). Experiment 4 extended this by finding that, relative to a neutral condition, low intensity negative affect (sadness) enhanced memory for peripherally presented information. Finally, in Experiment 5, the effects of sadness and threat on scope of memory were directly compared, finding that threat narrowed scope of memory, while sadness broadened scope of memory. Together, these results provide additional support for the motivational dimensional model of cognitive scope, in that high intensity emotions narrow cognitive scope, while low intensity emotions broaden cognitive scope.     

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).

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.
