Determinants of the shape of emotion intensity profiles

It has been shown that variability in the shape of emotion intensity profiles can be described in terms of three functional features, namely steepness at onset, skewness and number of peaks. However, it remains unclear which factors account for variability in each of these features. In the present study participants were asked to report intensity profiles of positive and negative emotions on a daily basis. Information was further collected regarding potential determinants of the functional features of the intensity profiles at three levels: trait-, episode-, and moment-determinants. Regarding steepness at onset, it was found for positive and negative emotions that intensity profiles have an especially explosive start when the eliciting stimulus is important, when the stimulus is still present during the beginning of the episode, and, in case of positive emotions, when the participant is an extravert. Concerning skewness, it was found for positive and negative emotions that profiles reach their peak more often towards the end when the eliciting stimulus is important, when the stimulus is absent during the beginning of the episode but present towards the end, and, in case of negative emotions, when the stimulus is uncontrollable. Regarding the number of peaks, it was found that profiles more often have multiple peaks when the eliciting stimulus is absent during the middle of the emotional episode.     

Mood-congruent false memories persist over time

There are two contrasting hypotheses that attempt to explain how emotion perception might be organised in the brain. One suggests that all emotions are lateralised to the right hemisphere whereas the other suggests that emotions may be differently lateralised according to valence. Here these two theories are contrasted, in addition to considering the role of emotional intensity in explaining possible differences in strength of lateralisation across emotions. Participants completed a Chimeric Faces Test for each of the six basic emotions: anger, disgust, fear, happiness, sadness and surprise. All emotions showed significant lateralisation to the right hemisphere, however, differences in strength of lateralisation within the right hemisphere were found. Stronger patterns of right hemisphere lateralisation were found for positive emotions and for emotions of higher intensity. The results support the right-hemisphere hypothesis, but suggest that there may be variability in organisation within the right hemisphere across different types of emotion.     

Hospital restructuring and nursing staff well-being: The role of perceived hospital and union support

Abstract

This research examined the effects of perceived hospital and union support on work satisfaction and psychological well-being of nursing staff during a period of hospital restructuring and downsizing. Data were collected from 1363 hospital-based nurses using anonymous questionnaires. Respondents reported receiving moderate levels of both hospital and union support during this period. However nursing staff reporting higher levels of perceived hospital support indicated greater job satisfaction, more job security, lower levels of psychological burnout and fewer psychosomatic symptoms, controlling for personal and work situation factors and extent of restructuring and downsizing initiatives. Implications for organizational management during downsizing and reorganization are drawn.     

Athletes' inclination to play through pain: a coping perspective

Previous studies have shown how social networks lead athletes to accept pain as a “part of the game,” which generates pressure on athletes to continue competing despite being in pain. Little is known, however, about the potential coping strategies that are related to pain behavior in sport. This study of 205 combat athletes examined whether pain coping strategies, including distraction from pain, praying, reinterpreting pain sensations, ignoring pain, and pain catastrophizing, are related to athletes’ inclination to play through pain. Results revealed that pain catastrophizing led athletes to reduce their physical involvement in their sport activity. Of particular interest was the moderating effect of ignoring pain such that ignoring pain significantly attenuated the negative effect of pain intensity on athletes’ inclination to play through pain. Few studies have tested and supported the contribution of pain coping to the prediction of behavior in real sport situations. By identifying which coping strategies athletes could use to maintain their physical involvement despite being in (sometimes intense) pain, the current study makes an important contribution for tailoring pain management programs for this at-risk population.     

中国、波兰大学生对基于声音线索的情绪知觉*

压力事件对初中生抑郁的影响:网络使用动机与网络使用强度的作用

为探讨压力事件对初中生抑郁的影响以及网络使用动机和网络使用强度在其中的作用,采用生活事件量表,网络使用动机量表,网络使用强度量表和流调中心用抑郁量表对武汉市内两所中学的913名初中生进行调查。结果发现：（1）压力事件与网络使用动机、网络使用强度和抑郁均呈显著正相关; （2）压力事件正向预测网络使用动机与网络使用强度,网络使用动机正向预测网络使用强度,网络使用强度正向预测抑郁; （3）网络使用动机中,社会补偿动机正向预测抑郁,而好友联系动机与休闲娱乐动机负向预测抑郁; （4）压力事件通过网络使用动机和网络使用强度的链式中介作用影响抑郁。研究结果强调压力事件不仅可以直接影响初中生抑郁,还可以通过网络使用动机和网络使用强度间接影响初中生抑郁。     

Effects of music on vocal stereotypy in children with autism

We examined the effects of manipulating the intensity (i.e., volume) of music on engagement in vocal stereotypy in 2 children with autism. Noncontingent access to music decreased immediate engagement in vocal stereotypy for each participant, but it produced only marginal effects on subsequent engagement in the behavior (i.e., after withdrawal). Manipulating the intensity of music did not produce differential effects on immediate engagement in vocal stereotypy. The implications of the results and applications for future research are discussed.     

Positive effects of low intensity recorded maternal voice on physiologic reactions in premature infants

ObjectiveTo evaluate the effect of low intensity recorded maternal voice on the physiologic reactions of healthy premature infants in the neonatal intensive care unit (NICU).MethodsPhysiologic responses of 20 healthy preterm infants in the NICU of Shariati Hospital, Tehran, were obtained during a 15 min intervention including three 5 min periods (no-sound control, audio recorded playback of mother’s voice, no-sound post-voice). The intervention was presented three times a day for three consecutive days. During each intervention, oxygen saturation (%, OSPR), heart rate (HR), and respiratory rate (RR) were recorded at 1 min intervals over the 15 min and then averaged over each 5 min period, resulting in 3 averages for each variable for each intervention.ResultsRepeated Measures Analysis of Variance were employed to examine each variable separately. Over the three days, comparison of oxygen saturation over each of the three periods (before, during voice, after) revealed an increase in oxygen saturation during the voice period, compared to the pre-voice period, which persisted over the post-voice period; there were no differences between the voice and post-voice periods. Analyses of the HR and RR data showed a decrease in both variables during the voice period compared to the pre-voice period which persisted over the post-voice period. Again, there were no differences between the voice and post-voice periods.ConclusionExposure to low intensity recorded maternal voice has positive effects on the preterm infants ‘physiologic responses.     

The effect of positive affect on conflict resolution: Modulated by approach-motivational intensity

The motivational dimensional model of affect proposes that the influence of positive affect on cognitive processing is modulated by approach-motivational intensity. The present research extended this model by examining the influence of positive affect varying in approach-motivational intensity on conflict resolution—the ability to resolve interference from task-irrelevant distractors in order to focus on the target. The global–local task (Experiment 1) and letter-Flanker task (Experiment 2) were used to measure conflict resolution. Additionally, the 4:2 mapping design that assigns two kinds of task-relevant stimuli to one response key and two more to another response key was used in these two tasks to dissociate stimulus and response conflict. Results showed that positive affect varying in approach motivation had opposite influences on conflict resolution. The opposite influences are primarily reflected in low approach-motivated positive affect impairing, while high approach-motivated positive affect facilitating the resolution of response conflict. Conversely, the stimulus conflict was slightly influenced. These findings highlight the utility of distinguishing stimulus and response conflict in future research.
