The tip-of-the-tongue state (TOT) is the feeling that accompanies temporary inaccessibility of an item that a person is trying to retrieve. TOTs have been studied experimentally since the seminal work of Brown and McNeill (1966). TOTs are experiences that accompany some failed or slow retrievals, and they can result in changes in retrieval behavior itself, allowing us to study the interplay among experience, retrieval, and behavior. We often attribute the experience of the TOT to the unretrieved target, but TOTs are based on a variety of cues, heuristics, or sources of evidence, such as partial information, related information, and cue familiarity, that predict the likelihood of overcoming retrieval failure. We present a synthesis of the direct-access view, which accounts for retrieval failure, and the heuristic–metacognitive view, which accounts for the experience of the TOT. We offer several avenues for future research and applications of TOT theory and data.  相似文献

We examined the daily dynamics among self‐concept clarity and identity processes, and their effects on distress, among a sample of 580 Dutch adolescents. Participants completed measures of identity, self‐concept clarity, anxiety and depression at annual intervals; and daily single‐item measures of self‐concept clarity, identity commitments and reconsideration across three 5‐day weeks. We examined (a) cross‐lagged associations of self‐concept clarity to identity commitment and reconsideration and (b) associations of daily fluctuations in self and identity processes to later anxiety and depression. Results indicated that self‐concept clarity and identity commitments influence one another reciprocally across days, and that day‐to‐day fluctuations in identity predicted later anxiety and depression. Results are discussed in terms of self and identity processes and their effects on distress. Copyright © 2010 John Wiley & Sons, Ltd.  相似文献

This article examines whether unrealistically viewing a romantic partner as resembling one's ideal partner accelerates or slows declines in marital satisfaction among newlyweds. A longitudinal study linked unrealistic idealization at the time of marriage to changes in satisfaction over the first 3 years of marriage. Overall, satisfaction declined markedly, a finding that is consistent with past research. However, seeing a less-than-ideal partner as a reflection of one's ideals predicted a certain level of protection against the corrosive effects of time: People who initially idealized their partner the most experienced no decline in satisfaction. The benefits of idealization remained in analyses that controlled separately for the positivity of partner perceptions and the possibility that better adjusted people might be in better relationships.  相似文献

The present study examined the role of neuroticism and extraversion in the effects of written emotional disclosure in patients diagnosed with gynaecological cancer. It was hypothesized that high levels of neuroticism would be associated with an increase in distress after emotional disclosure as mediated by heightened negative affect and avoidance post-disclosure. Conversely, we expected high extraversion to be associated with decreased distress as mediated by heightened positive moods and a decrease in avoidance. Eighty-eight participants were randomly assigned to participate in an expressive writing task versus a control writing task. Distress and avoidance were assessed at baseline and 6 months post-writing. Negative and positive mood were assessed immediately following writing. Multiple regression confirmed that neuroticism but not extraversion moderates the effects of emotional disclosure on distress, however no significant mediating relationships were found.  相似文献

Two mechanisms have been proposed regarding relations between parental responses to adolescent affective behaviours and the development of depression: the elicitation of parental negativity and the suppression of parental aggression. This study aimed to investigate the boundary conditions under which these two mechanisms operate in relation to the prospective prediction of Major Depressive Disorder (MDD) onset in adolescence. A community sample of 159 adolescents (aged 11–13 years) with no history of MDD completed a family interaction assessment with their mothers, and were followed-up with a diagnostic interview 2–3 years later. Results showed that onset of MDD was prospectively predicted by the elicitation of maternal aggression in response to adolescent aggression (in girls only) and maternal dysphoria in response to adolescent aggression, as well as the suppression of maternal aggression and dysphoria in response to adolescent dysphoria. Thus, support was obtained for both the elicitation of negativity mechanism in relation to maternal responses to adolescents’ aggressive behaviours, and the suppression of aggression mechanisms in relation to maternal responses to adolescents’ dysphoric behaviours. Mothers’ responses to adolescents’ aggressive and dysphoric behaviours may differentially influence the risk of MDD onset for adolescents over time.  相似文献

Smoking during pregnancy is a persistent public health problem that has been linked to later adverse outcomes. The neonatal period--the first month of life--carries substantial developmental change in regulatory skills and is the period when tobacco metabolites are cleared physiologically. Studies to date mostly have used cross-sectional designs that limit characterizing potential impacts of prenatal tobacco exposure on the development of key self-regulatory processes and cannot disentangle short-term withdrawal effects from residual exposure-related impacts. In this study, pregnant participants (N = 304) were recruited prospectively during pregnancy, and smoking was measured at multiple time points, with both self-report and biochemical measures. Neonatal attention, irritable reactivity, and stress dysregulation were examined longitudinally at three time points during the first month of life, and physical growth indices were measured at birth. Tobacco-exposed infants showed significantly poorer attention skills after birth, and the magnitude of the difference between exposed and nonexposed groups attenuated across the neonatal period. In contrast, exposure-related differences in irritable reactivity largely were not evident across the 1st month of life, differing marginally at 4 weeks of age only. Third-trimester smoking was associated with pervasive, deleterious, dose–response impacts on physical growth measured at birth, whereas nearly all smoking indicators throughout pregnancy predicted level and growth rates of early attention. The observed neonatal pattern is consistent with the neurobiology of tobacco on the developing nervous system and fits with developmental vulnerabilities observed later in life.  相似文献

Despite the existence of speech errors, verbal communication is successful because speakers can detect (and correct) their errors. The standard theory of speech-error detection, the perceptual-loop account, posits that the comprehension system monitors production output for errors. Such a comprehension-based monitor, however, cannot explain the double dissociation between comprehension and error-detection ability observed in the aphasic patients. We propose a new theory of speech-error detection which is instead based on the production process itself. The theory borrows from studies of forced-choice-response tasks the notion that error detection is accomplished by monitoring response conflict via a frontal brain structure, such as the anterior cingulate cortex. We adapt this idea to the two-step model of word production, and test the model-derived predictions on a sample of aphasic patients. Our results show a strong correlation between patients’ error-detection ability and the model’s characterization of their production skills, and no significant correlation between error detection and comprehension measures, thus supporting a production-based monitor, generally, and the implemented conflict-based monitor in particular. The successful application of the conflict-based theory to error-detection in linguistic, as well as non-linguistic domains points to a domain-general monitoring system.  相似文献

This study utilized a multi-informant approach to investigate the concurrent association between peer victimization and functioning at school in a predominantly Latino sample of 135 children (55 boys; 80 girls) in the third, fourth, and fifth grades. The children attended elementary schools in economically distressed urban neighborhoods. Victimization by peers was associated with low grade point averages (GPA) and poor school engagement. Mediation analysis showed that school engagement explained the relation between peer victimization and GPA. Moderator analyses indicated that the negative association between peer victimization and school engagement was exacerbated for children with numerous friends in their classrooms. Additional moderator analyses revealed that the negative association between victimization and engagement was stronger for children with many aggressive friends. The results extend past research by investigating a mediator and moderators of the association between peer victimization and functioning at school in an understudied population.  相似文献
