The current study examines the neural correlates of 8-to-12-year-old children and adults producing inflected word forms, specifically regular vs. irregular past-tense forms in English, using a silent production paradigm. ERPs were time-locked to a visual cue for silent production of either a regular or irregular past-tense form or a 3rd person singular present tense form of a given verb (e.g., walked/sang vs. walks/sings). Subsequently, another visual stimulus cued participants for an overt vocalization of their response. ERP results for the adult group revealed a negativity 300–450 ms after the silent-production cue for regular compared to irregular past-tense forms. There was no difference in the present form condition. Children’s brain potentials revealed developmental changes, with the older children demonstrating more adult-like ERP responses than the younger ones. We interpret the observed ERP responses as reflecting combinatorial processing involved in regular (but not irregular) past-tense formation. 相似文献

The presence of posttraumatic stress disorder (PTSD) symptoms and posttraumatic growth (PTG) following a critical incident were examined among firefighters from eight predominantly European countries. A sample of 1916 firefighters completed the Impact of Event Scale–Revised (IES–R) and the Posttraumatic Growth Inventory–Short Form (PTGI–SF) with reference to a critical incident they had experienced. Analyses indicated both negative and positive posttraumatic outcomes could derive from experiencing critical incidents in the line of duty. The analyses also showed country differences exist regarding firefighters’ PTSD symptoms and PTG. It is recommended that future researchers examine factors that could evoke such national differences. 相似文献

Using the think/no-think paradigm, we examined the effect of a meaningful connection between emotionally neutral cues and targets on initial learning and later recall by students in dysphoric or nondysphoric mood states. Compared to meaningfully connected cue-target pairs, unrelated pairs were less easily learned and more easily forgotten, even when initial learning was controlled. Depressive deficits were obtained in initial learning (only marginally) and final recall. When examined separately within each cuing condition, the recall deficit associated with depressed mood was restricted to the unrelated condition, but when initial learning differences were controlled this deficit was only marginally significant. Results are discussed in relation to other recent findings concerning depression-related performance in this paradigm and to findings of depression and memory more generally. 相似文献

Non‐anxious college students first performed a semantic‐judgement task that was designed to train either threat‐related or threat‐unrelated interpretations of threat‐ambiguous homographs (e.g. mug). Next they performed an ostensibly separate transfer task of constructing personal mental images for single words, in a series that included new, threat‐ambiguous homographs. In two experiments, the number of threat‐related interpretations in the transfer task significantly increased following threat‐related experience during the training phase, compared to other training conditions. We conclude that interpretive biases typically shown by anxious people can be established in non‐anxious students in ways that generalize to novel tasks and materials.

Play observations with a total of 400 toddlers and preschoolers were videotaped and rated for Intensity and Quality of play with their parents. Parents were asked about perceived stress and personality characteristics (Big 5). Child's motor, cognitive skills, temperament, and internalizing behaviors were assessed. Study 1 investigated the robustness of play across child age and gender, and examined differences between fathers and mothers. Study 2 explored the vulnerability of play with fathers of children born preterm (PT‐fathers) and fathers who had experienced adverse childhoods (AC‐fathers). Study 3 investigated child internalizing behaviors. Intensity of play was maintained almost independently of child age and gender. It was similar for AC‐ and PT‐fathers, and similar to maternal Intensity. In contrast, paternal Quality of play was higher with boys and independent of fathers’ personality and perceived parenting stress whereas maternal Quality of play was higher with girls and linked to mothers’ perceived parenting competence, acceptability of the child, and neuroticism. AC‐fathers scored significantly low on Quality, as did PT‐fathers, but the Quality of their play became better with growing child age, birth weight, and cognitive (but not motor and temperament) scores. Finally, child internalizing behaviors were negatively related to paternal Quality of play. 相似文献

Negative biases in cognition have been documented consistently in major depressive disorder (MDD), including difficulties in the ability to control the processing of negative material. Although negative information-processing biases have been studied using both behavioral and neuroimaging paradigms, relatively little research has been conducted examining the difficulties of depressed persons with inhibiting the retrieval of negative information from long-term memory. In this study, we used the think/no-think paradigm and functional magnetic resonance imaging to assess the cognitive and neural consequences of memory suppression in individuals diagnosed with depression and in healthy controls. The participants showed typical behavioral forgetting effects, but contrary to our hypotheses, there were no differences between the depressed and nondepressed participants or between neutral and negative memories. Relative to controls, depressed individuals exhibited greater activity in right middle frontal gyrus during memory suppression, regardless of the valence of the suppressed stimuli, and differential activity in the amygdala and hippocampus during memory suppression involving negatively valenced stimuli. These findings indicate that depressed individuals are characterized by neural anomalies during the suppression of long-term memories, increasing our understanding of the brain bases of negative cognitive biases in MDD. 相似文献

In this study three different groups of professional dancers (ballet, modern/contemporary and jazz/musical), which considerably vary with respect to the creativity-related demands involved in the respective dancing style, are compared with respect to psychometrically determined creativity, general mental ability and different facets of personality. Results indicate that modern/contemporary dancers, who are often required to freely improvise on stage, exhibited relatively high levels of verbal and figural creativity (as it was measured by means of psychometric creativity tests), followed by jazz/musical and finally by ballet dancers. With respect to personality, modern/contemporary dancers can be characterized as being less conscientious, higher on psychoticism and more open to experiences than the remaining experimental groups. In line with relevant research in this field, this study reveals some central personality characteristics of highly creative individuals which may be considered as important ingredients in the acquisition or actualization of exceptional creative potential. 相似文献
