In a series of experiments on immediate probed recognition for eight 3-digit numbers, it was shown that if the target modality involved auditory components and the effect of the similarity of the modality of the probe to that of the targets was controlled, unequivocal evidence was obtained for an auditory superiority effect (modality effect) for hit rates for the final items of the list. Moreover, false-alarm rates were significantly lower following targets with an auditory component than they were following silently seen targets. It is argued that this pattern of hits and false alarms is consistent with the idea that targets that have an auditory component yield memory representations that are better grouped as units than are those for targets that are only silently seen; in particular, if a new probe has a first digit that accidentally matches the first digit of a target item, it is more likely that the subject will mistakenly identify this new probe as old (give a false alarm) if the target has only been partially encoded because it was only silently seen.  相似文献

The present study examined whether employees high in negative affectivity (NA) are destined to be unhappy at work. Managerial employees provided information regarding perceptions of job characteristics, negative affectivity (NA), job satisfaction, and intentions to turnover. Using hierarchical regression, our findings suggest that employees who reported being high NA were more reactive to the environmental cues of perceived job scope. Specifically, NA interacted with job scope such that individuals high in NA who perceived their jobs as being higher (lower) in scope reported more (less) job satisfaction than did individuals low in NA. Implications for organizations and future research directions are discussed.  相似文献

Unlike English, Chinese uses a numerical system for naming months and days. This study explored whether this difference in naming affects the development of simple calendar calculation. Eight- and 10-year-old children as well as undergraduates in China and the United States were asked to name the day or month that comes a specified time before or after a given day or month. In each age group Chinese speakers primarily used calculation based on calendar names to solve these tasks, while English speakers primarily resorted to reciting the names. The magnitude of these differences was substantial; on difficult tasks Chinese fourth graders performed at speeds comparable to those of English-speaking adults. Implications for models of how linguistic structure affects cognition are discussed.  相似文献

The purpose of this study was to examine the extent to which factors in the nursing environment have differential effects on burnout levels among nurses high and low in negative affectivity (NA). Specifically, this field study examined the moderating relationships among role ambiguity, role conflict, and collective efficacy on the NA–burnout relationship among nurses in a hospital setting. Findings suggest that perceived role conflict exacerbates while perceptions of collective efficacy reduce specific dimensions of burnout for nurses high in NA. These results offer some evidence regarding which environmental characteristics may mitigate burnout for high-NA nurses.  相似文献

Belief revision theory concerns methods for reformulating an agent's epistemic state when the agent's beliefs are refuted by new information. The usual guiding principle in the design of such methods is to preserve as much of the agent's epistemic state as possible when the state is revised. Learning theoretic research focuses, instead, on a learning method's reliability or ability to converge to true, informative beliefs over a wide range of possible environments. This paper bridges the two perspectives by assessing the reliability of several proposed belief revision operators. Stringent conceptions of minimal change are shown to occasion a limitation called inductive amnesia: they can predict the future only if they cannot remember the past. Avoidance of inductive amnesia can therefore function as a plausible and hitherto unrecognized constraint on the design of belief revision operators.  相似文献

Parental overcontrol (OC), behavior that intrusively or dominantly restricts child autonomy, has been identified as a transdiagnostic risk factor for youth. However, it is as yet unknown whether the association between parental OC and child maladjustment remains even when OC is exerted infrequently or by attuned parents. Rather, the selective use of OC might steer children away from danger. Taking a developmental psychopathology approach, this study focuses on the larger parent–child relationship context, testing whether either the dose at which parents demonstrate OC or the degree to which children perceive their parents as attuned determines whether OC is risky or protective for adolescents’ adjustment. Among a community sample of 114 families of children followed from the ages of 12–18, we examine whether OC, behaviorally coded from triadic mother–father–child discussions in middle childhood, is associated with later risky behavior and anxiety symptoms in adolescence. Overcontrol exerted by either mothers or fathers had a curvilinear effect on adolescent risky behaviors, and this effect was moderated by children's perceived attunement. Although OC generally was associated with increased risky behaviors, low doses of OC or OC exerted by highly attuned parents protected against engagement in risky behaviors. No main effect of OC was observed on adolescent anxiety; however, mothers’ OC interacted with perceived parental attunement, such that OC exerted by less attuned parents predicted greater anxiety. Results underscore that the effect of parenting behaviors depends on the larger parent–child relationship context.  相似文献

This study aimed to distinguish personality traits that are widely associated with several types of externalizing behaviors from personality traits that are more selectively associated with one or only a few specific types of externalizing behavior. A wide range of externalizing behaviors (e.g. alcohol and drug use, risky driving, aggressive acts, sexual promiscuity and relationship infidelity, academic misconduct) typical among an undergraduate population (N?=?257) were examined along with a range of personality traits measured using the Section III personality model for the DSM-5. We found that externalizing behavior was best associated with the domain level trait Antagonism and, to a lesser degree, Disinhibition. Antagonism’s association with problematic behavior was primarily accounted for by the facet trait Deceitfulness. Deceitfulness was found to be associated with a wide range of behaviors including relationship infidelity, theft, aggressive acts, and drug and alcohol use. Associations between Disinhibition and problem behavior, especially risky driving and poor work or school performance, were best accounted for by the Irresponsibility facet, as opposed to the Impulsivity or Distractibility facet traits. This comprehensive multivariate approach is important for a more complete understanding of the complex relationship that exists between personality traits and externalizing behavior. A better understanding of factors precipitating externalizing behavior could ultimately lead to an increased ability to target interventions to individuals most susceptible to engage in problematic behavior.  相似文献

In order to evaluate the associations between computer-administered tasks of executive functioning (EF), and maladaptive personality domains and traits listed in DSM-5 Alternative Model of Personality Disorders, 53 consecutively admitted psychotherapy outpatients (female participants: n?=?27, 50.9%; male participants: n?=?26, 49.1%; participants’ mean age?=?37.28 years, SD?=?11.50 years) were administered the Psychology Experiment Building Language (PEBL) EF tasks and the Personality Inventory for DSM-5 (PID-5). According to rank-order correlation analyses, a number of non-negligible and specific associations were observed between selected PID-5 scales and indices of participants’ performance on EF tasks. MM robust regression models showed that participants’ performance on computer-administered EF tasks explained a non-negligible amount of variance in selected PID-5 scale scores (median R2 value?=?.17). As a whole, our trait-level analyses of PID-5 dimensions suggest the clinical usefulness of integrating self-reports and EF laboratory tasks in routine clinical assessment.  相似文献

Psychoanalytically oriented day hospital therapy, later manualized and named mentalization-based treatment (MBT), has proven to be a (cost-) effective treatment for patients with severe borderline personality disorder and a high degree of psychiatric comorbidity (BPD) in the United Kingdom (UK). As to yet it has not been shown whether manualized day hospital MBT would yield similar results when conducted by an independent institute outside the UK. We investigated the applicability and treatment outcome of 18-month, manualized day hospital MBT in the Netherlands by means of a prospective cohort study with 45 Dutch patients with severe BPD and a high degree of comorbid Axis I and Axis II disorders. Outcomes were assessed each six months. Symptom distress, social and interpersonal functioning, and personality pathology and functioning all improved significantly, with effect sizes between 0.7 and 1.7. Suicide attempts, acts of self-harm, and care consumption were also significantly reduced. The results indicate that MBT can effectively be implemented in an independent treatment institute outside the UK. This study also supports the clinical effectiveness of manualized day hospital MBT in patients with severe BPD and a high degree of psychiatric comorbidity.  相似文献
