We examined the separate and combined impact of gender composition and training method on both the performance and interpersonal behaviors exhibited in small work groups. Participants were scheduled in groups of three for two 1-h sessions that occurred 1 week apart. In Session 1, groups were trained to assemble the AM portion of a radio. In Session 2, groups were tested on their training. Analyses indicated that groups whose members were trained together took longer to assemble their radios and made more errors than groups whose members were trained apart. No performance differences were found between mixed-gender and same-gender groups. However, women were less task-oriented in mixed-gender than in same-gender groups, but men were more task-oriented in mixed-gender than in same-gender groups. Further, solo women were less talkative than women in the majority, whereas men were more talkative when they were solos rather than in the majority. Implications for the nature of training and gender composition in groups in the workplace are discussed. 相似文献

We explored whether event recency and valence affect people’s susceptibility to imagination inflation. Using a three-stage procedure, subjects imagined positive and negative events happening in their distant or recent past. First, subjects rated how confident they were that they had experienced particular positive and negative events in childhood or adulthood using a Life Events Inventory (LEI). Two weeks later, they imagined two positive and two negative events from the LEI. Finally, they rated their confidence on the LEI a second time. For positive events, subjects showed more imagination inflation for adulthood than childhood events. For negative events, they showed no difference in imagination inflation for adulthood and childhood events. We discuss factors that may influence source confusions for memories of the past and highlight directions for future research. 相似文献

Individuals with obsessive-compulsive disorder (OCD) often experience intrusive thoughts. These intrusions may be due to biases in information processing mechanisms, including attention, memory, and learning. To examine this hypothesis, we presented a modified negative priming (NP) paradigm with idiographically selected words to 19 individuals with OCD (OCs) and 19 matched non-anxious control participants (NACs). The words included OCD-relevant threat, OCD-relevant positive, and neutral words. This paradigm typically elicits positive priming because participants may learn the contingency between the prime and probe that facilitates responding [Frings and Wentura (2006). Strategy effects counteract distractor inhibition: NP with constantly absent probe distractors. Journal of Experimental Psychology: Human Perception and Performance, 32, 854-864]. As predicted, NACs showed facilitation (i.e., positive priming) rather than NP for all word types, whereas OCs exhibited facilitation for only neutral words. For positive words, OCs exhibited no priming and for threat words they exhibited NP. These results suggest that for idiographic, OCD-relevant threat information, individuals with OCD show difficulty learning the contingency between the information in the prime and probe displays relative to the NACs. 相似文献

Background . Research has demonstrated that working collaboratively can have positive effects on children's learning. While key factors have been identified which influence the quality of these interactions, little research has addressed the influence of children's achievement goals on collaborative behaviour. Aims . This paper investigates the influence of mastery and performance goals on the nature of children's collaborative participation while playing a problem‐solving computer game with a peer. Sample . Forty‐eight primary schoolchildren aged 8–10 years were divided into two groups: those displaying strong personal goal preferences (dispositional group: N = 14) and those whose goal preferences were context‐dependent, displaying no consistent bias for either mastery or performance goals (context‐dependent: N = 34). Children were paired on the basis of same gender, year group, and goal orientation. Method . Context‐dependent pairs were assigned to either a mastery or a performance condition in which they received goal‐focused instructions. Dispositional pairs received only the instructions to collaborate given to all groups. Collaborative sessions were videotaped and interactions coded. Results . Children who were assigned mastery goals engaged in significantly more elaborated problem‐solving discussion whilst children who were assigned performance goals engaged in more executive help seeking and displayed lower levels of metacognitive control. Dispositional pairs shared some similar patterns, according to goal orientation, as context‐dependent pairs. Conclusions . Goal‐focused instructions can be used to influence the nature and quality of children's paired interactions. Instructing children towards mastery goals appears to promote a more collaborative style of interaction. 相似文献

This special section was motivated by a resurgence in the view that it is impossible to investigate perceptual and cognitive development without considering how it is affected by, and intertwined with, infants' and children's action in the world. This view has long been foundational to the field, yet contemporary investigations of the effects of acting on cognition and perception have been limited. The research showcased in this section indicates that this trend is changing as researchers consider anew the ways in which cognition derives structure from action. The work presented here illustrates the breadth of these potential effects across ages and domains of development, and it highlights the breadth of methods that can be recruited to investigate them. This new research focus provides insight for the mechanisms by which action affects perception and cognition and at the same time reveals that much remains to be learned. 相似文献

Building on Nicholls's earlier work, we examined developmental changes in children's understanding of effort and ability when faced with a negative outcome. In a sample of 166 children and adolescents (ages 5-15 years), younger children conflated the meaning of effort and ability, explaining that smart students work hard, whereas older children understood effort and ability to be reciprocally related constructs, explaining that smart students do not need to work as hard. Understanding the reciprocal relation between effort and ability was correlated with age. Age-related changes in the meaning and correlates of effort and ability were also examined. Developmental implications for attribution theory and achievement motivation are discussed. 相似文献

ABSTRACT A trait approach to personality has many implications for psychotherapy. Given that traits contribute to the expression of symptoms of common psychiatric disorders, are moderately heritable, and relatively stable (yet also dynamic to some extent), long‐term change in symptoms is possible but is likely to be limited. Analogous to the manner in which genes set the reaction range for phenotype, standing on certain traits may set the patient's “therapeutic range.” On the other hand, some of the same traits that may limit the depth of therapeutic benefits might also increase their breadth. In addition, taking the patient's standing on different traits into account can inform the choice of therapeutic strategy and targets and can affect the formation of the therapeutic alliance and compliance with self‐help exercises. Finally, other aspects of personality beyond traits, such as ego development and narrative identity, also appear to have important implications for psychotherapy. 相似文献

The current study examined the persistence and phenotypic presentation of inattention/overactivity (I/O) into early adolescence,
in a sample of institution reared (IR) children adopted from Romania before the age of 43 months. Total sample comprised 144
IR and 21 non-IR Romanian adoptees, and a comparison group of 52 within-UK adoptees, assessed at ages 6 and 11 years. I/O
was rated using Rutter Scales completed by parents and teachers. I/O continued to be strongly associated with institutional
deprivation, with continuities between ages 6 and 11 outcomes. There were higher rates of deprivation-related I/O in boys
than girls, and I/O was strongly associated with conduct problems, disinhibited attachment and executive function but not
IQ more generally, independently of gender. Deprivation-related I/O shares many common features with ADHD, despite its different
etiology and putative developmental mechanisms. I/O is a persistent domain of impairment following early institutional deprivation
of 6 months or more, suggesting there may be a possible pathway to impairment through some form of neuro-developmental programming
during critical periods of early development. 相似文献

Theory of Mind (ToM) and Executive Function (EF) have been associated with autism and with attention-deficit hyperactivity
disorder (ADHD), and hence might play a role in similar syndromes found following profound early institutional deprivation.
In order to examine this possibility the current study included a group of 165 Romanian adoptees, of whom 144 were adopted
into the UK from deprived institutional settings before 43months of age, and a group of 52 within-UK adoptees, all adopted
before 6months of age. Both groups were assessed at 6 and 11years. The Strange Stories task was used to assess ToM and the
Stroop task was used to assess EF, both at age 11. The Romanian adoptees displayed deficits in both ToM and EF compared with
the within-UK adoptee group. The degree of deficit was greater for children who had experienced more than 6months of institutional
deprivation. Deficits in both domains (ToM and EF) were associated with each of the three apparently deprivation-specific
problems, namely quasi-autism, disinhibited attachment and inattention/overactivity. Statistical analyses indicated a mediating
role for both ToM and EF with respect to quasi-autism; possibly a partial mediating role for EF with respect to inattention/overactivity;
and probably no mediating role for either ToM or EF in the case of disinhibited attachment. In conclusion, there is evidence
for a possible mediating role for ToM and EF in the development of some apparently deprivation-specific difficulties in institution-reared
Romanian adoptees, but neither accounts for the overall pattern of deprivation-related difficulties. 相似文献
