ObjectiveThe purpose of this study is to assess the potential unique and relative mediating effects of three interpersonal risk factors (i.e., excessive reassurance-seeking [ERS], negative feedback seeking [NFS], and rejection sensitivity [RS]) in the relationship between childhood emotional abuse (CEA) and depressive symptoms.MethodOne hundred eighty-five undergraduates were followed over a four-month interval. Participants completed assessments of childhood abuse history, ERS, NFS, and RS, and depressive symptoms at baseline, as well as depressive symptoms at four-month followup.ResultsFindings from single-mediator analyses indicated that RS and NFS, but not ERS, mediated the relationship between CEA and prospective depressive symptoms, after accounting for childhood sexual and physical abuse, as well as baseline depressive symptoms. In our multi-mediator model, only RS remained a significant mediator of the relationship between CEA and prospective depressive symptoms.ConclusionsThe current study provides preliminary evidence that negative behavioral styles may function as a mechanism linking prior experiences of CEA to subsequent depressive symptoms. Clinical implications of these findings suggest that targeting maladaptive behavioral tendencies, particularly RS, may be an effective adjunct in behavioral modification treatments of CEA victims at risk for depression. 相似文献

On-road research suggests that driver feedback combined with a token economy (a system of delayed reinforcement whereby tokens or points are distributed following a desired behaviour and are later exchanged for desired items) can reduce speeding, and that an incentive system without feedback may be sufficient to achieve this reduction. In two studies, we investigated the necessary and sufficient conditions required for this intervention to reduce speeding, and the efficacy of conducting such research using a driving simulator. Study 1 served to validate the simulator procedure. Participants completed a simulated drive while receiving feedback on their speed and a speed-based token economy. The intervention decreased their speeding compared with that of a control group. Study 2 investigated the amount of speed reduction that could be achieved with just one intervention component (i.e., feedback alone or a token economy alone) compared with feedback and a token economy combined or a control condition. Participants completed a 30-min simulated drive. Overall, drivers who received feedback combined with a token economy spent the least amount of time driving above the speed limit, had the slowest mean speed, and had the smallest standard deviation of speed. Drivers exposed to a token economy alone showed similar speed reductions. However, drivers exposed to feedback alone drove at speeds similar to control participants. Replicating these results under more realistic operating conditions could inform policy-makers and car manufacturers. Furthermore, the simulator proved a cost-effective and efficient means for examining the intervention. 相似文献

A slow-down in reaction time (RT) after committing an error is a well-known effect. Recently, Notebaert and colleagues (Notebaert et al., 2009; Núñez Castellar, Kuhn, Fias, & Notebaert, 2010) suggested that posterror slowing is a reaction to the infrequent nature of errors. After infrequent errors, posterror slowing was observed but after infrequent correct trials, postcorrect slowing was observed. These data were obtained in a paradigm with trial-by-trial feedback. In this study we tested whether posterror slowing was similar with and without immediate feedback. We manipulated the overall accuracy parametrically per condition (50%, 70%, and 90% accuracy) and predicted an increase in posterror slowing as the accuracy increased. This linear effect was observed with and without immediate feedback. The data are interpreted in terms of an orienting response towards unexpected events. 相似文献

The role of feedback was investigated with respect to conscious and unconscious knowledge acquired during artificial grammar learning (AGL). After incidental learning of training sequences, participants classified further sequences in terms of grammaticality and reported their decision strategy with or without explicit veridical feedback. Sequences that disobeyed the learning structure conformed to an alternative structure. Feedback led to an increase in the amount of reported conscious knowledge of structure (derived rules and recollections) but did not increase its accuracy. Conversely, feedback maintained the accuracy of unconscious knowledge of structure (intuition or familiarity-based responses) which otherwise degraded. Results support a dual-process account of AGL. They suggest that implicit learning of the to-be-rejected structure at test contaminates familiarity-based classifications whereas feedback allows competing familiarity signals to be contextualised, which is incompatible with theories that consider familiarity context-insensitive. 相似文献

We propose that women's increased generalized sensitivity to rewards during the fertile phase of the menstrual cycle causes them to seek more variety in rewards when they are in the fertile phase than when they are not in the fertile phase of the cycle. In Studies 1–3, across the reward domains of mating and hedonic food, we show that women seek more variety in rewards when closer to ovulation. Moreover, we provide support for the proposition that women's increased reward sensitivity during the fertile phase of the menstrual cycle causes their greater variety seeking. Specifically, in Study 3, we show that fertile women's greater variety seeking does not extend to non-rewards, such as non-hedonic food. Our findings suggest that behavioral effects of women's hormonal shifts during the menstrual cycle are not limited to the mating domain and may extend to a wide category of reward domains. 相似文献

Intimate partner violence (IPV) is a social problem associated with significant morbidity; however, victims do not always utilize treatment and resources. One's readiness to change might be one variable impacting his or her pursuit of treatment and other resources. This study investigated correlates of readiness to change, and readiness to change's impact on treatment utilization. Data were collected from 223 women residing in battered women's shelters. Correlational analyses find that generally victims with more psychopathology and distress, as well as more social support, were more ready to change. Posttraumatic stress disorder symptoms, overall distress, and social support were the strongest predictors of readiness to change. Finally, victims higher in readiness to change were more likely to seek mental health treatment and other IPV-related services. 相似文献

ABSTRACT Although the prevalence of drug use in the young adult population in Turkey is still far below the figures reported for most European Union countries and the United States, there seems to be a noteworthy increase in drug use, especially among high school and college students. The purpose of the present study was to examine the extent of drug use among college students in Turkey and to identify some of the individual-difference variables associated with drug use. Participants were 781 college students. A survey package including (a) measures of sensation seeking–risk taking, self-esteem, affectivity level, global mental health, overall life satisfaction, and the rate and nature of substance use and (b) demographic questions was administered to the participants during regularly held class meetings. A logistic regression analysis revealed that sensation seeking?risk taking, parental education level, smoking, and frequency of alcohol use predicted illicit drug experience. Implications of the findings and limitations of the study are discussed using the context of the study as a framework. 相似文献

Risk taking behavior can be both adaptive and maladaptive depending on context. The majority of studies on risk taking, however, focus on clinical populations and dangerous or harmful risk taking. Individual differences in learning during risk taking are rarely examined in relation to task performance. The present study examined risk taking and associated outcomes in an exploration-based instrumental learning task (Balloon Emotional Learning Task; BELT), which presented a series of balloons in which participants pump up for points. Consistent with prior work, sensation seeking predicted increased risk taking behavior. Importantly, however, a significant interaction between sensation seeking and associative sensitivity, an attentional construct defined as the frequency and remoteness of automatic cognitive activity, was found. Specifically, among individuals high in sensation seeking, associative sensitivity predicted fewer balloon explosions and an increase in points earned on the balloon condition with the most potential for feedback driven learning. Thus, these findings suggest that sensation seekers are a heterogeneous group, and secondary traits such as associative sensitivity moderate risk taking and learning according to context. 相似文献

In this exploratory study, we examined the extent to which both workplace bullies and victims possess bully-typifying traits, using a 22-item scale that simultaneously measures perpetrators and targets of negative workplace acts. Participants were 224 Canadian university students aged 18–47 with prior work experience. Bivariate correlational analyses determined that bullying others was positively associated with measures of Machiavellianism, narcissism, psychoticism, aggression, and disinhibition. Being a victim was positively associated with the same Machiavellianism, narcissism, psychoticism, and aggression measures. Hierarchical regression analyses indicated that an “alternative dark triad” of Machiavellianism, narcissism, and psychoticism related significantly to bullying scores; while psychoticism and Machiavellianism related significantly to victim scores. Aggression and sensation seeking measures failed to account for significant variance in bully or victim scores beyond the triad variables. The vast majority of bullies (89.7%) and many victims (41.7%) were bully/victims, operationally defined as being both perpetrators and targets at least once per week in the last 6 months. Researchers and employers would do well to recognize the presence of bully/victims in their efforts to understand and reduce workplace bullying. 相似文献
