Mental noise can be defined as less reliable information processing. Individuals with high levels of mental noise are thought to be disadvantaged in cognitive, emotional, and behavioural realms. The present five studies (total N=298) investigated such potential disadvantages among normally functioning college undergraduates. Mental noise was operationalised in terms of the reaction time coefficient of variation (RTCV), a measure of RT variability that corrects for average levels of mental speed. Individuals with higher RTCV exhibited less effective cognitive control (Studies 1 and 5), less controlled behaviour (Study 2), and were more prone to negative emotional experiences (Study 3) and depressive symptoms (Study 4). Study 5 extended these results and found that individuals higher (versus lower) in RTCV were more adversely affected by their attentional lapses in daily life. Results converge on the idea that mental noise is an important individual difference dimension with multiple adverse correlates and consequences.  相似文献

This investigation examined the impact of social support messages on patient health outcomes. Forty‐one American Indian, Alaska Native, and Native Hawaiian patients received a total of 618 e‐mail messages from their healthcare provider (HCP). The e‐mail messages were divided into 3,565 message units and coded for instances of emotional social support. Patient glycosulated hemoglobin scores (HbA1c) showed significantly improved glycemic control and emotional social support messages were associated with significant decreases in HbA1c values. Patient involvement with the system, measured by system login frequency and the frequency of uploaded blood glucose scores to the HCP, did not predict change in HbA1c.  相似文献

Objective: The objective was to examine an executive control difficulty perspective on individual differences in cortisol reactivity using a daily protocol.

Design: Fifty participants competed a laboratory stressor task and individualdifferences in cortisol reactivity were quantified.

Main outcome measures: Daily attentional control, conflicting thoughts, error reactivity, worry and mindfulness were assessed.

Results: The findings support the idea that as cortisol responses to stress get larger (as an individual difference), attentional control ceases to function as it should in terms of variables that should predict (mindfulness) and follow from (e.g. worry) it.

Conclusion: The findings support the idea that individual differences in cortisol reactivity can be conceptualised in terms of ineffectual attentional control.  相似文献

Abstract

Cluster analysis derived MMPI profile types were compared for three distinct illness populations: chronic low back pain (CLBP), mixed headache (HA), and cardiac disease (CD). Results replicated previous findings in the chronic pain and cardiac literatures. Differences between diagnostic groups and genders were found for the prevalence of the derived MMPI profile types. Results indicated that, in males, the two chronic pain groups had similar profile types and similar relative frequencies of these types, but both differed from the CD sample. The chronic pain groups tended to have a greater number of patients with pathological and distressed MMPI profile types and a lesser representation in the subclinical profile type compared to the CD sample. Similar findings were obtained for females, though the CLBP group tended to have a higher frequency of highly distressed, pathological profiles than either the HA or CD groups. Results suggested that the MMPI may be a measure of response to illness rather than reflecting predisposing personality types for any given illness and that the higher frequency of highly distressed profiles in the chronic pain samples reflects the increased suffering of those populations compared to other illnesses.  相似文献

Purpose: Pediatric brain tumors are the second most common cancer diagnosis in individuals under age 20 and research has documented significant neurocognitive, psychosocial, and emotional late effects. Associations among these deficits have not been adequately considered and the role of survivors’ coping with stress in relation to deficits is unknown. Further, research has yet to examine neurobiological processes related to neurocognitive, psychosocial, and emotional difficulties in survivors through the use of functional neuroimaging. Method: Questionnaire measures and functional neuroimaging were used to examine the neurocognitive, psychosocial, and emotional functioning and coping responses of survivors of pediatric brain tumors (= 17; age 8–16) and healthy children (= 15). Results: Survivors experienced elevated levels of psychosocial and behavioral/emotional difficulties relative to healthy controls and normative data. Increases in brain activation in prefrontal and other anterior regions in response to a working memory task were associated with better psychosocial functioning, use of engagement coping strategies, and less use of disengagement coping strategies. Regression analyses suggest coping accounts for a significant portion of the association between brain activation and behavioral/emotional functioning. Conclusions: This study extends late-effects research by examining neurobiological processes associated with psychosocial and emotional difficulties. These findings contribute to our understanding of difficulties in survivors and provide a foundation for research exploring these associations and mediators of deficits in future longitudinal studies.  相似文献

The ability to process and integrate cross‐modal input is important for many everyday tasks. The current paper reviews theoretical and empirical work examining cross‐modal processing with a focus on recent findings examining infants' and children's processing of arbitrary auditory–visual pairings. The current paper puts forward a potential mechanism that may account for modality dominance effects found in a variety of cognitive tasks. The mechanism assumes that although early processing of auditory and visual input is parallel, attention is allocated in a serial manner with the modality that is faster to engage attention dominating later processing. Details of the mechanism, factors influencing processing of arbitrary auditory–visual pairings, and implications for higher‐order tasks are discussed. Copyright © 2009 John Wiley & Sons, Ltd.

Over the years, researchers have focused on ways to facilitate creativity in the workplace by looking at individual factors and organizational factors that affect employee creativity (Woodman, Sawyer, & Griffin, 1993 ). In many cases, the factors that affect creativity are examined independently. In other words, it is uncommon for researchers to look at the interaction among individual and organizational factors. In this study, it is argued that to get a true understanding of how to maximize creativity in the workplace, organizational researchers must look at the interaction between organizational factors and individual factors that affect employee creativity. More specifically, the current study looked at an individual's perceptions about his or her ability to be creative (i.e., individual factor) and perceptions of requirements for creativity in the workplace (i.e., an organizational factor). The results indicated that individuals who have a high belief about their ability to be creative (an individual factor) were most creative when they also perceived requirements for creativity in the workplace (an organizational factor). Furthermore, individuals who had low perceptions of creative ability were still able to perform creatively when they had high perceptions of requirements for creativity. This suggests that, to maximize creativity, organizations should focus on both individual and organizational factors that affect employee creativity.  相似文献

Evaluation is a core topic of interest in both social psychology and linguistic theory, but there are relatively few social-cognitive studies examining the “online” consequences of affective metaphor. The experiments presented here sought to investigate such online consequences in relation to an understudied class of metaphors linking evaluation to size (i.e., “bigger is better”). Consistent with such metaphors, we found that positive (vs. negative) words were evaluated more quickly (Experiment 1) and accurately (Experiment 2) when presented in a larger (vs. smaller) font size. Parallel and opposite effects were found for negative words. A third experiment demonstrated that words presented in a larger font size were evaluated more favorably, thus extending size effects to evaluative judgments. Together, the studies converge on the importance of size metaphors for understanding evaluation from a social-cognitive perspective.  相似文献

This article examines how physicians and patients interactionally accomplish the transition from the activity of history taking to that of physical examination. Prior research focuses on participants' reliance on overt verbal resources (e.g., physicians' requests for permission to examine patients or explanations that foreshadow examination). Using the methodology of conversation analysis, this article draws on a corpus of 40 primary‐care encounters to demonstrate that: (a) In addition to verbal behavior, nonverbal behavior is integral to the accomplishment of transitions; and (b) patients' understandings of physicians' verbal and nonverbal behavior as communicating transitions are achieved through situating those behaviors in other contexts of embodied action, talk, activity, and social structure (i.e., the phase structure of encounters). Findings have implications for: (a) the theoretic relationship between verbal and nonverbal behavior in terms of social meaning, (b) what it means to explain transitions and reduce patients' uncertainty, (c) the organization of physician‐patient interaction, and (d) the relationship and interface between macro‐ and microconceptualization of context.  相似文献
