It is currently controversial whether priming on implicit tasks and discrimination on explicit recognition tests are supported by a single memory system or by multiple, independent systems. In a Psychological Review article, Berry and colleagues used mathematical modeling to address this question and provide compelling evidence against the independent-systems approach. 相似文献

The current study examined gender differences in mothers' and fathers' internal state language (ISL), children's use of ISL, and whether ISL was related to parents' ratings of the children's social skills. Fifty‐seven (28 boys, 29 girls) toddler/preschool children (M age = 32.5 months, SD = 5.38 months) were observed separately with their mothers and fathers in their homes while they discussed pictures of children's facial expressions of emotions. Parents completed a questionnaire concerning their child's social–emotional behaviours (i.e. BASC‐2). Parents used more ISL with sons compared with daughters, and sons used more ISL with mothers than with fathers. No overall differences were found between mothers' and fathers' ISL. Children's social skills as rated by mothers were predicted by mothers' ISL comments, whereas children's social skills as rated by fathers were predicted by children's age and fathers' ISL clarifications. Implications and limitations of the study are discussed. Copyright © 2012 John Wiley & Sons, Ltd. 相似文献

Self predictions are often optimistically biased, even for recurrent events. People could generate more realistic predictions by using information about past experiences, however they tend to disregard this cognitive approach. Drawing on Construal Level Theory, we propose that increases in construal level facilitate the use of information from past experience, and thereby increase prediction accuracy. This proposal was tested in two studies examining predictions of personal spending. Consistent with the hypotheses, individuals induced to construe the prediction target at a higher level of abstraction generated more accurate predictions (Study 1) and the effect of increased construal level on prediction was attributable to a greater reliance on past experience (Studies 1 and 2). The findings indicate that high-level construal can sometimes benefit prediction accuracy. 相似文献

Since knowledge intensive work often requires self-management, one might fear that persons who are dependent on work success for self-esteem will have difficulties in finding a healthful and sustainable balance between internal needs and external demands. Accordingly, we examined to what degree work-related performance-based self-esteem (PBS) was linked to work and health behaviors in 392 knowledge workers (226 women, 166 men). In the women group, multiple binary logistic regression analyses with repeated measurements showed that the PBS score was associated with 10 of the 17 examined work and health behaviors. For men the corresponding figure was 3 of 17. In both men and women, higher PBS scores were positively associated with reports of efforts and strivings for work as well as attending work while ill. In conclusion, statistically significant relationships between PBS and work and health behaviors were more clearly visible among women than men. Whether this gender difference is dependent on the study design, or on true inherent differences between women and men, cannot be concluded with any certainty. However, persons who described themselves as being relatively more dependent on work accomplishments for a high self-esteem, as expressed by the PBS score, seem to display work behaviors that may lessen their restitution time. In addition, they also seem to be more prone to work while sick. 相似文献

Many differences in brain activity have been reported between persons who stutter (PWS) and typically fluent controls during oral reading tasks. An earlier meta-analysis of imaging studies identified stutter-related regions, but recent studies report less agreement with those regions. A PET study on adult dextral PWS (n = 18) and matched fluent controls (CONT, n = 12) is reported that used both oral reading and monologue tasks. After correcting for speech rate differences between the groups the task-activation differences were surprisingly small. For both analyses only some regions previously considered stutter-related were more activated in the PWS group than in the CONT group, and these were also activated during eyes-closed rest (ECR). In the PWS group, stuttering frequency was correlated with cortico-striatal-thalamic circuit activity in both speaking tasks. The neuroimaging findings for the PWS group, relative to the CONT group, appear consistent with neuroanatomic abnormalities being increasingly reported among PWS. 相似文献

We report two experiments that investigated the widely held assumption that speakers use the addressee's discourse model when choosing referring expressions (e.g., Ariel, 1990; Chafe, 1994; Givón, 1983; Prince, 1985), by manipulating whether the addressee could hear the immediately preceding linguistic context. Experiment 1 showed that speakers increased pronoun use (and decreased noun phrase use) when the referent was mentioned in the immediately preceding sentence compared to when it was not, even though the addressee did not hear the preceding sentence, indicating that speakers used their own, privileged discourse model when choosing referring expressions. The same pattern of results was found in Experiment 2. Speakers produced more pronouns when the immediately preceding sentence mentioned the referent than when it mentioned a referential competitor, regardless of whether the sentence was shared with their addressee. Thus, we conclude that choice of referring expression is determined by the referent's accessibility in the speaker's own discourse model rather than the addressee's. 相似文献

The relative efficacy of positive task interdependence, positive resource interdependence, and individualistic learning were compared with achievement and academic and personal social support. The authors randomly assigned to conditions 66 7th-grade Italian students with no previous experience in cooperative learning. They participated in 6 90-min instructional sessions dealing with the dangers of smoking, alcohol, and drugs. The results indicated that students assigned to the task-interdependence and resource-interdependence conditions achieved higher and perceived greater peer academic support than did students working individually. Students in the resource-interdependence condition showed a higher perception of peer personal support than students assigned to the other conditions. 相似文献

Motor control research relies on theories, such as coordination dynamics, adapted from physical sciences to explain the emergence of coordinated movement in biological systems. Historically, many studies of coordination have involved inter-limb coordination of relatively few degrees of freedom. This study looked at the high-dimensional inter-limb coordination used to perform the golf chip shot toward six different target distances. This study also introduces a visualization of high-dimensional coordination relevant within the coordination dynamics theoretical framework. A specific type of Artificial Neural Network (ANN), the Self-Organizing Map (SOM), was used for the analysis. In this study, the trajectory of consecutive best-matching nodes on the output map was used as a collective variable and subsequently fed into a second SOM which was used to create visualization of coordination stability. The SOM trajectories showed changes in coordination between movement patterns used for short chip shots and movement patterns used for long chip shots. The attractor diagrams showed non-linear phase transitions for three out of four players. The methods used in this study may offer a solution for researchers from a coordination dynamics perspective who intend to use data obtained from discrete high-dimensional movements. 相似文献

This meta‐analysis investigates the degree to which achievement is positively associated with motivation within situations characterized by positive, negative, and no interdependence. First, the relative effects of positive, negative, and no interdependence on motivation and achievement were determined. Then the amount of variance in achievement explained by motivation (and vice versa) was calculated. In all, 629 independent studies were included, representing 26 different countries. Results also showed that motivation accounted for 14% of the variance in achievement (and vice versa). When the lowest‐quality studies were eliminated, the percentage of achievement explained by motivation increased to 24%. Positive interdependence resulted in greater motivation and achievement than did negative or no interdependence. Implications for theory and application are discussed. 相似文献
