Effects of Rumination and Worry on Sleep

Recent research suggests that the stress-sleep relationship is mediated by pre-sleep arousal (PSA) and that cognitive arousal has a stronger mediating effect than somatic arousal; however, this has not been directly tested. Using multilevel moderated mediation, we compared the effects of cognitive arousal and somatic arousal within the stress-sleep relationship. We also assessed whether two forms of repetitive negative thought—rumination and worry—are similarly involved in the stress-sleep relationship. Data was collected from 178 participants across the United States via an online platform. Participants completed baseline self-report surveys examining rumination tendencies and worry tendencies. Over the course of 2 weeks, participants completed daily questionnaires assessing daily stress, PSA, and sleep quality. Results indicated that indirect effects from stress to sleep quality via PSA were statistically significant at low and high levels of rumination and worry, and people at high levels of rumination and worry had stronger relationships between stress and PSA. Across all models, cognitive arousal consistently accounted for more of the variance in the stress-sleep relationship as compared to somatic arousal. Implications for the cognitive behavioral treatment of insomnia are discussed.     

Clarifying the role of impulsivity in dietary restraint: A structural equation modeling approach

This study was designed to clarify the relationship between the four dimensions of impulsivity in Whiteside and Lynam’s (2001) model and the two aspects of dietary restraint (Concern for Dieting and Weight Fluctuation) in a non-clinical sample. Data were collected from a volunteer community sample (N = 216) of women who responded to two self-report instruments related to impulsivity (UPPS Impulsive Behavior Scale, Whiteside & Lynam, 2001) and dietary restraint (Restraint Scale, Polivy, Herman, & Warsh, 1978). A structural equation model was tested. The model provided a good fit to the data (χ²/df = 1.64, p < .0001, RMSEA = 0.054, 90% CI = 0.050–0.058, p-value for test of close fit (RMSEA > 0.05) = .035) and revealed that Concern for Dieting was positively related to Urgency (standardized β = 0.25, p < .01). Weight Fluctuation was related to lack of Perseverance (standardized β = 0.25, p < .01) and tended to relate to Sensation Seeking (standardized β = 0.17, p = .056). Urgency and lack of Perseverance were found to play a significant role in predicting Concern for Dieting and Weight Fluctuation.     

Cognitive self-consciousness and meta-worry and their relations to symptoms of worry and obsessional thoughts

The relation between cognitive self-consciousness and meta-worry, and their association with symptoms of worry and obsessional thoughts were examined. 53 undergraduate students completed the expanded version of the Cognitive Self-consciousness Scale, the Meta-worry subscale of the Anxious Thoughts Inventory, the Penn State Worry Questionnaire, and the Padua Inventory-Revised. Analysis showed that cognitive self-consciousness and meta-worry were moderately correlated (r =.57). Further, both constructs were positively associated with symptoms of worry and obsessional thoughts. When controlling for cognitive self-consciousness, metaworry remained significantly correlated to both types of symptoms. Yet, when controlling for meta-worry, correlations between cognitive self-consciousness and symptoms of worry and obsessional thoughts clearly attuned and were no longer significant. These findings suggest that meta-worry is more important for understanding excessive, intrusive thought patterns than the mere tendency to monitor one's thoughts.     

Vocal indicators of facilitative interpersonal skills

The facilitative interpersonal skills (FIS) method uses simulations of difficult client moments as a test of helpers' ability to remain therapeutic in therapeutically stressful situations. A total of 135 participants completed the FIS task as part of a training in helping skills and provided verbal responses that were assessed by trained raters for interpersonal skills. Audio recordings of these verbal responses were then analysed acoustically for fundamental frequency (F0), spectral slope and F0 range. Mean F0 and F0 range were more highly associated with trained raters' ratings of FIS for female participants than for male participants, although F0 range was associated with FIS of both males and females. The results suggest that F0 is associated with FIS for females, especially the FIS items that are indicative of emotional expression and verbal fluency. Findings are discussed as possibly indicating that some expression of higher F0 in response to distressed client situations may be part of interpersonal skills, such that more skilled therapists respond to stressful client situations with a higher F0.     

The relationship between the cognitive style and play behaviors of 3-to-5-year-old children

Children (N=1276) ages 3 to 5 were tested for their cognitive style (field dependence/independence) and their play behaviors were observed and recorded. A repeated measures multivariate analysis of variance (MANOVA) for the children's play behaviors was found to be significant by the Wilks' lambda criterion, indicating that FD and FI individuals played differently. That is, FD children engaged more in play than did FI ones. Three significant interactions were found for cognitive style and play behaviors: (a) cognitive style and play behaviors, (b) age, cognitive style, and play behaviors, and (c) age, sex, cognitive style, and play behaviors. Four- and 5-year-old FD children usually had the most play behaviors except for the leadership abilities where 3-year-old FI children had the highest scores in dramatic play. In contrast, 3- and 4-year-old FI children had the least play behaviors except for frequency of play where 5-year-old FI children had the lowest scores in all of the play areas. The children's play behaviors were also influenced by their cognitive style, sex and age.     

From armchair to wheelchair: how patients with a locked-in syndrome integrate bodily changes in experienced identity

Different sort of people are interested in personal identity. Philosophers frequently ask what it takes to remain oneself. Caregivers imagine their patients' experience. But both philosophers and caregivers think from the armchair: they can only make assumptions about what it would be like to wake up with massive bodily changes. Patients with a locked-in syndrome (LIS) suffer a full body paralysis without cognitive impairment. They can tell us what it is like. Forty-four chronic LIS patients and 20 age-matched healthy medical professionals answered a 15-items questionnaire targeting: (A) global evaluation of identity, (B) body representation and (C) experienced meaning in life. In patients, self-reported identity was correlated with B and C. Patients differed with controls in C. These results suggest that the paralyzed body remains a strong component of patients' experienced identity, that patients can adjust to objectives changes perceived as meaningful and that caregivers fail in predicting patients' experience.     

Psychopathic personality traits in the workplace: Implications for interpersonally- and organizationally-directed counterproductive and citizenship behaviors

Relatively little is known about the relations between psychopathic traits and interpersonally-directed versus organizationally-directed workplace behaviors despite the implications of these traits for maladaptive (e.g., bullying, harassing, white-collar crime, slacking) and adaptive (e.g., improving the workplace, supporting others) workplace behaviors. In a sample of employed US-based community members (N?=?352), we investigated the relations between the Triarchic Psychopathy Measure (TriPM) and an expanded version of the Levenson Self-Report Psychopathy Scale (E-LSRP), on the one hand, and interpersonal and organizational counterproductive behaviors and citizenship behaviors directed towards co-workers and the organization, on the other. As predicted, we found stronger positive associations between impulsive-antisocial traits (Disinhibition, Antisocial) and both interpersonal and organizational workplace deviance; however, these traits did not relate significantly to citizenship behaviors. We further found that interpersonal traits (Boldness, Egocentric) may play an adaptive role in the workplace, as demonstrated by increased citizenship behaviors. Affective traits (Callous, Meanness) were related to lesser engagement in citizenship behaviors and higher engagement in some interpersonally-directed counterproductive behaviors. In several analyses, statistical interactions among triarchic psychopathy traits, but not E-LSRP traits, predicted adaptive and maladaptive workplace behaviors. Our results suggest that employees’ psychopathic traits bear differential implications for both adaptive and maladaptive workplace behavior, and that these traits may operate in concert to increase the likelihood of such behavior.

     

Using ambiguous plaid stimuli to investigate the influence of immediate prior experience on perception

In a series of three experiments, we used an ambiguous plaid motion stimulus to explore the behavioral and electrophysiological effects of prior stimulus exposures and perceptual states on current awareness. The results showed that prior exposure to a stimulus biased toward one percept led to subsequent suppression of that percept. In contrast, in the absence of stimulus bias, prior perceptual experience can have a facilitative influence. The suppressive effects caused by the prior stimulus were found to transfer to an ambiguous plaid test stimulus rotated 180º relative to the adaptation stimulus, but were abolished if (1) the ambiguous test stimulus was only rotated 90º relative to the adaptation stimulus or (2) the adaptation stimulus was heavily biased toward the component grating percept. Event-related potential recordings were consistent with the involvement of visual cortical areas and suggested that the influence of recent stimulus exposure may involve recruitment of additional brain processes beyond those responsible for initial stimulus encoding. In contrast, the effects of prior and current perceptual experience appeared to depend on similar brain processes. Although the data presented here focus on vision, the work is discussed within the context of data from a parallel series of experiments in audition.
