Although considerable evidence has linked sleep disturbance to symptoms of psychopathology, including repetitive negative thinking, few studies have examined how sleep disturbance may predict repetitive negative thinking over time. Further, no study to date has examined specific mechanisms that may account for this relationship. The present study sought to address these gaps in the literature by testing focusing and shifting attentional control as two potential mediators of the relationship between sleep disturbance and repetitive negative thinking over a 6-month period. A final sample of 445 unselected community participants completed measures of sleep disturbance and repetitive negative thinking at Time 1, measures of focusing and shifting attentional control 3 months later, and measures of repetitive negative thinking again 6 months later. Results revealed that focusing, but not shifting, attentional control mediated the relationship between sleep disturbance and repetitive negative thinking, specifically, worry, rumination, and obsessions. These findings provide preliminary evidence for focusing attentional control as a candidate mechanism that may explain the causal role of sleep disturbance in the development of repetitive negative thinking observed in various disorders.  相似文献

Visual inspection of single-subject data is the primary method for behavior analysts to interpret the effect of an independent variable on a dependent variable; however, there is no consensus on the most suitable method for teaching graph construction for single-subject designs. We systematically replicated and extended Tyner and Fienup (2015) using a repeated-measures between-subjects design to compare the effects of instructor-led, video-model, and no-instruction control tutorials on the graphing performance of 81 master's students with some reported Microsoft Excel experience. Our mixed-design analysis revealed a statistically significant main effect of pretest, tutorial, and posttest submissions for each tutorial group and a nonsignificant main effect of tutorial group. Tutorial group significantly interacted with submissions, suggesting that both instructor-led and video-model tutorials may be superior to providing graduate students with a written list of graphing conventions (i.e., control condition). Finally, training influenced performance on an untrained graph type (multielement) for all tutorial groups.  相似文献

The current study examined the extent to which the Ohio Scales, Short Form, Problem Severity domain was able to perform as a reliable and valid measure within a large community mental health sample of multiethnic youth and families in Hawai?i. Using a sample of 1,125 youth participants, who were 59.1% male (n = 665), with a mean age of 12.96 (SD = 3.4), confirmatory factor analyses pointed to four factors (Externalizing, Delinquency, Anxiety, Depression), with subscale internal reliabilities varying slightly. The majority of convergence patterns between Problem Severity domain and related Child and Adolescent Functional Assessment Scale subscales were significantly correlated in the expected directions. Problem Severity subscale scores were mostly able to discriminate between youth with and without pertinent mental health diagnoses. Youth- and caregiver-report Problem Severity domain subscale and total scores were significantly correlated in the predicted directions. Finally, significant youth improvement was evident at 3-month follow-up, and Problem Severity intake and 3-month follow-up scores were significantly and positively related to one another. Implications and suggestions for future research are discussed.

When people reflect on their important values, they may become more attuned to the needs of others. Two longitudinal field experiments examined whether a subtle value-affirmation manipulation can initiate relatively enduring increases in young adolescents' prosocial feelings (Study 1; Mage = 12.9) and prosocial behaviors (Study 2; Mage = 12.9). Participants completed a brief writing exercise that affirmed the values they deemed either most important (value-affirmation group) or unimportant (control group). As predicted, the value affirmation, coupled with a booster affirmation 6 weeks later, caused increases in prosocial feelings and behaviors over the 3-month study period. Antisocial students who were value-affirmed showed especially strong increases in prosocial behavior. These results suggest that "gentle passions" can be aroused in youth by cost- and time-efficient means. The practical utility of value affirmations will need to be evaluated in future work.  相似文献

The failure to consider the future consequences of one's behavior is a major risk factor for aggression. Aggressive people tend to act first, and think later. Some people focus on the -here and now rather than on the future, a tendency measured by the Consideration of Future Consequences (CFC) scale (Strathman, Gleicher, Boninger, & Edwards, 1994). Alcohol intoxication is a neuro-biological variable that produces similar effects. Participants in the present experiment completed the CFC scale and then consumed either an alcohol or a placebo beverage. Next, they competed against a same-sex ostensible partner on an interpersonally adversarial competitive task in which the winner could administer electric shocks to the loser (the aggression measure). As expected, aggression was highest in intoxicated persons with low CFC scores. Being unconcerned about the future consequences of one's actions, in conjunction with acute alcohol intoxication, combine in a pernicious manner to increase aggression.  相似文献

We developed a multi-faceted prejudice habit-breaking intervention to produce long-term reductions in implicit race bias. The intervention is based on the premise that implicit bias is like a habit that can be broken through a combination of awareness of implicit bias, concern about the effects of that bias, and the application of strategies to reduce bias. In a 12-week longitudinal study, people who received the intervention showed dramatic reductions in implicit race bias. People who were concerned about discrimination or who reported using the strategies showed the greatest reductions. The intervention also led to increases in concern about discrimination and personal awareness of bias over the duration of the study. People in the control group showed none of the above effects. Our results raise the hope of reducing persistent and unintentional forms of discrimination that arise from implicit bias.  相似文献

Research has clearly shown that violent video games can increase aggression. It is less clear why they do. This study investigates the mediating effect of the hostile expectation bias (i.e., tendency to perceive hostile intent on the part of others) on the link between violent video game exposure and aggression. French college students (N = 136) played either a violent or nonviolent game for 20 minutes. Afterwards, they read ambiguous story stems about potential interpersonal conflicts, and listed what they thought the main characters would do or say, think, and feel as the story continued. Aggression was measured using a competitive computer game in which the winner could blast the loser with loud noise through headphones. As hypothesized, video game violence increased the hostile expectation bias, which, in turn, increased aggression. Effects were larger for men than women. Thus one reason why violent games increase aggression is because they increase hostile expectations.  相似文献

The self‐esteem movement has been around since the 1970s, and may have influenced how much value people place on self‐esteem. We predicted a negative relationship between age and the amount of value placed on self‐esteem boosts. We also investigated the correlates of liking versus wanting self‐esteem boosts (and other pleasant rewards) on depression. A nationally representative sample of American adults (N = 867) indicated how much they liked and wanted several pleasant rewards (i.e., sex, food, alcohol, money, friendship, self‐esteem boost). They also completed a standardized measure of depressive symptoms. As expected, there was a negative relationship between age and valuing self‐esteem boosts, sex, and alcohol. People with depressive symptoms wanted self‐esteem boosts, even though they did not like them very much. Similar effects were obtained for depressive symptoms and alcohol and friendship. This is the first research to show that self‐esteem boosts are more valued among a nationally representative sample of younger American adults. It also is the first research to explore the association between depression and the motivation to boost self‐esteem. People with depressive symptoms want self‐esteem, and may pursue it, but this pursuit may feel unrewarding because they do not derive pleasure from it.  相似文献

This investigation examined the factor structure of 8 well-validated self-report measures that assess traits that fall under the rubric of an "aggressive personality" and then determined how those factor(s) moderated the association between alcohol intoxication and aggression. Participants were 518 (252 men and 266 women) healthy social drinkers between 21 and 35 years of age. Following the consumption of an alcoholic or a placebo beverage, participants were tested on a laboratory aggression paradigm in which electric shocks were received from, and administered to, a fictitious opponent. Aggression was operationalized as the shock intensities and durations administered to the opponent. Results demonstrated a unidimensional factor structure for the aggressive personality traits, which were then combined into a latent variable. The aggressive personality variable moderated the alcohol-aggression relation. Specifically, alcohol was significantly more likely to increase aggression in persons with higher, compared with lower, aggressive personality scores.  相似文献

Task effects in semantic processing were investigated by contrasting the neural activation associated with two semantic categorization tasks (SCT) using event-related fMRI. The two SCTs involved different decision categories: is it an animal? vs. is it a concrete thing? Participants completed both tasks and, across participants, the same core set of items were presented in both tasks. Results showed task differences in the neural activation associated with these items: in the animal SCT there was greater activation in a number of frontal and temporal regions, including left superior and middle temporal gyri, while in the concrete SCT there was greater activation in left medial frontal gyrus and bilaterally in the precentral gyri. These results are interpreted as evidence of top-down modulation of semantic processing; participants make adjustments to optimize performance in a given task and these adjustments have consequences for the activation observed.  相似文献
