Emotion regulation choice in an evaluative context: the moderating role of self-esteem

Evaluative contexts can be stressful, but relatively little is known about how different individuals who vary in responses to self-evaluation make emotion regulatory choices to cope in these situations. To address this gap, participants who vary in self-esteem gave an impromptu speech, rated how they perceived they had performed on multiple evaluative dimensions, and subsequently chose between disengaging attention from emotional processing (distraction) and engaging with emotional processing via changing its meaning (reappraisal), while waiting to receive feedback regarding these evaluative dimensions. According to our framework, distraction can offer stronger short-term relief than reappraisal, but, distraction is costly in the long run relative to reappraisal because it does not allow learning from evaluative feedback. We predicted and found that participants with lower (but not higher) self-esteem react defensively to threat of failure by seeking short-term relief via distraction over the long-term benefit of reappraisal, as perceived failure increases. Implications for the understanding of emotion regulation and self-esteem are discussed.     

Hemispheric asymmetries in auditory distraction

Serial-verbal short-term memory is impaired by irrelevant sound, particularly when the sound changes acoustically (the changing-state effect). In contrast, short-term recall of semantic information is impaired only by the semanticity of irrelevant speech, particularly when it is semantically related to the target memory items (the between-sequence semantic similarity effect). Previous research indicates that the changing-state effect is larger when the sound is presented to the left ear in comparison to the right ear, the left ear disadvantage. In this paper, we report a novel finding whereby the between-sequence semantic similarity effect is larger when the irrelevant speech is presented to the right ear in comparison to the left ear, but this right ear disadvantage is found only when meaning is the basis of recall (Experiments 1 and 3), not when order is the basis of recall (Experiment 2). Our results complement previous research on hemispheric asymmetry effects in cross-modal auditory distraction by demonstrating a role for the left hemisphere in semantic auditory distraction.     

The development of memory maintenance: Children’s use of phonological rehearsal and attentional refreshment in working memory tasks

Past research suggests that children begin to phonologically rehearse at around 7 years of age. Less is known regarding the development of refreshment, an attention-based maintenance mechanism. Therefore, the use of these two maintenance methods by 6- and 8-year-olds was assessed using memory span tasks that varied in their opportunities for maintenance activity. Experiment 1 showed that nonverbal processing impaired both groups’ performance to similar extents. Experiment 2 employed phonologically similar or dissimilar memory items and compared the effects of verbal versus nonverbal processing on recall. Both groups showed evidence of phonological maintenance under nonverbal processing but not under verbal processing. Furthermore, nonverbal processing again impaired recall. Verbal processing was also more detrimental to performance in 8-year-olds than in 6-year-olds. Together, the results suggest that nonverbal processing impairs recall by obstructing refreshment and that developmental change in maintenance between 6 and 8 years of age consists primarily of an increase in phonological rehearsal.     

Attention,mindwandering, and mood

We tested the hypothesis that mindwandering and external distraction are both manifestations of a common state of reduced attention focus, and examined how both relate to reported level of happiness. We conducted real-time sampling of people’s experience of mindwandering, irrelevant distraction (e.g. by music, phone, etc.), and happiness levels, in two studies with 524 people undertaking common daily-life activities. All irrelevant external distractions were positively correlated with mindwandering. Indeed mindwandering duration could be predicted from the reported duration of external distraction, when controlling for a range of background variables. An exploratory factor analysis of mindwandering and distraction reports suggested a single underlying construct. In addition, duration of irrelevant distraction by both mobile phones and mindwandering was significantly associated with reduced reported levels of happiness. The results are consistent with the hypothesis that that a state of reduced attention focus underlies both mindwandering and distractibility and clarify the link with happiness.     

Background music stints creativity: Evidence from compound remote associate tasks

Background music has been claimed to enhance people's creativity. In three experiments, we investigated the impact of background music on performance of Compound Remote Associate Tasks (CRATs), which are widely thought to tap creativity. Background music with foreign (unfamiliar) lyrics (Experiment 1), instrumental music without lyrics (Experiment 2), and music with familiar lyrics (Experiment 3) all significantly impaired CRAT performance in comparison with quiet background conditions. Furthermore, Experiment 3 demonstrated that background music impaired CRAT performance regardless of whether the music induced a positive mood or whether participants typically studied in the presence of music. The findings challenge the view that background music enhances creativity and are discussed in terms of an auditory distraction account (interference‐by‐process) and the processing disfluency account.     

The Relative and Perceived Impact of Irrelevant Speech,Vocal Music and Non-vocal Music on Working Memory

The ability to retain and manipulate information for brief periods of time is crucial for proficient cognitive functioning but working memory (WM) is susceptible to disruption by irrelevant speech. Music may also be detrimental, but its impact on WM is not clear. This study assessed the effects of vocal music, equivalent instrumental music, and irrelevant speech on WM in order to clarify what aspect of music affects performance and the degree of impairment. To study this, 60 college students completed WM tests (digit span) in the presence of irrelevant speech, vocal music, instrumental (karaoke) versions of the vocal music, and silence. As expected, both speech and vocal music degraded performance. WM performance with instrumental music was better than with vocal music but not significantly different from either silence or speech. Familiarity with song lyrics had little effect on performance. People were poor judges of the degree of memory impairment resulting from various irrelevant sounds. This study was reviewed and approved by the Clemson University Institutional Review Board.     

Effects of cognitive load presence and duration on driver eye movements and event detection performance

This study examined the effects of cognitive load on driving performance for interactions with an in-vehicle information system (IVIS) that varied in duration from 1 to 4 min. Twelve participants drove in a simulator while intermittently performing the IVIS task. There were three IVIS conditions: interacting with the IVIS, non-IVIS periods between IVIS interactions, and baseline driving without the IVIS task. Contrary to our hypothesis, driver response to lead vehicle braking was surprisingly uniform across IVIS conditions. IVIS interaction did undermine driver ability to detect the bicyclist along the side of the road, and some of these performance decrements persisted after the IVIS interaction had ended. Reaction time for bicyclist detection increased from the first to the subsequent minutes of the interaction. Eye movements were influenced by the IVIS conditions but not by task duration. Both ANOVA and factor analyses revealed that some of the changes in eye movements were concurrent with IVIS interaction while others persisted after the driver completed the IVIS interaction. Overall, the findings suggest that two mechanisms might account for the distraction-related performance decrements in this study: competition for processing resources and interference due to activation of competing goals.     

Helping Children and Caregivers Cope with Repeated Invasive Procedures: How Are We Doing?

This paper discusses recent developments in the medical and psychological management of child behavioral distress during invasive (i.e., needle stick) procedures for diagnosis and treatment of chronic pediatric disorders. Along with a review of relevant studies from the medical, pediatric psychology and behavior analysis literatures, representative data are presented from recent research on pediatric procedural pain management. The impact of increasing use of implanted subcutaneous intravenous catheters (ports) and decreased reliance on intravenous cannulation is discussed. Similarly, the effects (and limitations) of more frequent use of topical anesthesia to prepare needle sites also are presented. The continuing need for adjunctive, nonpharmacological (i.e., cognitive and behavioral) interventions for procedural pain is emphasized, and recent studies on distraction and counter-conditioning-based treatments are described. Future research is encouraged on (1) behavioral interventions in relation to day-to-day contextual variables that modulate treatment effects and (2) the development of efficient screening measures to identify children and families who are least likely to cope effectively with repeated procedures, allowing them to be given greater priority for allocation of limited resources for psychosocial intervention.     

Distraction for Pediatric Immunization Pain: A Critical Review

The paper provides a critical review of distraction for pediatric immunizations in order to determine clinical practicality and efficacy of this commonly employed intervention. The MEDLINE and PsycINFO databases were searched to identify papers that included an evaluation of a distraction intervention as a method of pediatric immunization pain management. Fifteen papers were included in this review. Effect sizes were calculated to estimate the clinical significance of findings. In order to examine possible differences in effect sizes related to distraction characteristics, chi square analyses were conducted. Results indicate that distraction is clinically effective in the reduction of pain during pediatric immunizations. Support is found for behavioral and cognitive explanations of distraction mechanisms. Further, various distraction stimulus characteristics were found to be associated with the clinical significance of findings. This article is based on the preliminary examination paper of the first author under the direction of the second, at West Virginia University.     

How distraction affects pedestrian response: Evidence from behavior patterns and cortex oxyhemoglobin changes

ObjectivesDistracted walking is a major cause of pedestrian road traffic injuries, but little is known about how distraction affects pedestrian safety. The study was designed to explore how visual and auditory distraction might influence pedestrian safety.MethodsThree experiments were conducted to explore causal mechanisms from two theoretical perspectives, increased cognitive load from the distraction task and resource competition in the same sensory modality. Pedestrians’ behavior patterns and cortex oxyhemoglobin changes were recorded while they performed a series of dual tasks.ResultsFour primary results emerged: (a) participants responded more slowly to both visual and auditory stimuli in traffic, as well as walked more slowly, while talking on the phone or text messaging compared to when undistracted or listening to music; (b) when participants completed pedestrian response tasks while distracted with a high cognitive load, their response was significantly slower and poorer than when they carried out a lower cognitive load distraction task, (c) participants had higher levels of oxy-Hb change in cortices related to visual processing and executive function while distracted with a higher cognitive load; and (d) participants' responses to traffic lights were slower and resulted in a higher activation in prefrontal cortex and occipital areas when distracted by a visual distraction task compared to when distracted with an auditory task; similarly, brain activation increased significantly in temporal areas when participants responded to an auditory car horn task compared to when they responded to visual traffic lights.ConclusionsBoth distracting cognitive load demands and the type of distraction task significantly affect young adult pedestrian performance and threaten pedestrian safety. Pedestrian injury prevention efforts should consider the effects of the type of distracting task and its cognitive demands on pedestrian safety.
