Children remember words from ignorant speakers but do not attach meaning: evidence from event‐related potentials 下载免费PDF全文
Although we know much about the conditions under which children demonstrate selective social learning, we have a limited understanding of the cognitive mechanisms by which children's selectivity manifests. Here, we report findings from a brain electrophysiological (ERP) study designed to determine the extent to which words presented by ignorant speakers were later both familiar to children and associated with semantic meaning. Forty‐eight children (mean age = 6.5 years) first experienced novel word training from either a knowledgeable or an ignorant speaker. Children's ERPs were subsequently recorded as they heard a recording of the speaker using the novel word, followed by a picture of either the object the word was paired with during training (congruent) or a distractor object that was also present during training (incongruent). Children trained by a knowledgeable speaker showed both N200 and N400 effects to the incongruent word–referent pairings, thereby suggesting that the novel words were both familiar and bore a semantic association. In contrast, children trained by an ignorant speaker demonstrated only the N200 effect, thereby suggesting that the word–referent links were familiar, but not associated with semantic meaning. These findings provide evidence that selective word learning involves the disruption of processes specifically associated with semantic consolidation of word learning events. 相似文献

How attitudes change and affect behavior depends, in large part, on their strength. Strong attitudes are more resistant to persuasion and are more likely to produce attitude‐consistent behavior. But what influences attitude strength? In this article, we explore a widely discussed, but rarely investigated, factor: an individual's political discussion network. What prior work exists offers a somewhat mixed picture, finding sometimes that disagreeable networks weaken attitudes and other times that they strengthen attitudes. We use a novel national representative dataset to explore the relationship between disagreeable networks and attitude strength. We find, perhaps surprisingly, no evidence that disagreements in networks affect political attitude strength. We conclude by discussing likely reasons for our findings, which, in turn, provide a research agenda for the study of networks and attitude strength. 相似文献

The current study aimed to develop and evaluate a measure of parenting knowledge, the Knowledge of Parenting Strategies Scale (KOPSS); specifically, to establish the scales internal reliability, ensure a clinically appropriate length, provide a community sample for future comparison, demonstrate adequate test–retest reliability and convergent validity, and to compare the scale to dysfunctional discipline styles. A total of n?=?865 parents were involved in the development and evaluation of the scale. In Study 1, data was collected from n?=?229 parents and Rasch analyses revealed seven items did not fit the measurement model. Study 2 involved a further sample of community families (n?=?346) and revealed the scale could be further shortened to 16 items. Study 3 revealed the scale has good test–retest reliability over a one-week period (r?=?.88, p?<?.001). Study 4 demonstrated convergent validity through a comparison to the Knowledge of Effective Parenting Scale (r?=?.583, p?=?.009). Study 5 utilised a sample of community families (n?=?190), revealing the scale was negatively correlated with hostile and lax discipline (r?=??.29, p?<?.001; r?=??.15, p?<?.05). Lastly, Study 6 showed scores on the KOPSS significantly improved following clinic-based and Internet-based Behavioural Parent Training. The KOPSS was found to be a valid and reliable measure of parenting knowledge of effective parenting strategies, which can be used to evaluate knowledge acquisition in parenting programs, and test the role of knowledge in behaviour change. 相似文献

Being grateful has been associated with many positive outcomes, including greater happiness, positive affect, optimism, and self-esteem. There is limited research, however, on the associations between gratitude and different domains of life satisfaction across cultures. The current study examined the associations between gratitude and three domains of life satisfaction, including satisfaction in relationships, work, and health, and overall life satisfaction, in the United States and Japan. A total of 945 participants were drawn from two samples of middle aged and older adults, the Midlife Development in the United States and the Midlife Development in Japan. There were significant positive bivariate associations between gratitude and all four measures of life satisfaction. In addition, after adjusting for demographics, neuroticism, extraversion, and the other measures of satisfaction, gratitude was uniquely and positively associated with satisfaction with relationships and life overall but not with satisfaction with work or health. Furthermore, results indicated that women and individuals who were more extraverted and lived in the United States were more grateful and individuals with less than a high school degree were less grateful. The findings from this study suggest that gratitude is uniquely associated with specific domains of life satisfaction. Results are discussed with respect to future research and the design and implementation of gratitude interventions, particularly when including individuals from different cultures. 相似文献

Previous studies have shown that telehealth can be an effective way to deliver behavior‐analytic services. In this study, we provided a demonstration of the use of telehealth to assess and initiate treatment of problem behavior in an outpatient clinic. We coached parents of children with autism via telehealth to conduct functional analyses during 1 appointment that lasted 1 hr and subsequently coached them as they implemented functional communication training during 3 subsequent appointments (15 min each). Social functions were identified for most children, and problem behavior was reduced by an average of 65.1%. 相似文献

The present investigation examined the sexual dimorphic patterns of cardiorespiratory fitness to working memory in preadolescent children (age range: 7.7–10.9). Data were collected in three separate studies (Study 1: n = 97, 42 females; Study 2: n = 95, 45 females; Study 3: n = 84, 37 females). All participants completed a cardiorespiratory fitness assessment in addition to a specific measure of working memory (i.e. the operation span task, the n‐back task, or the Sternberg task). Results from all three samples revealed that higher cardiorespiratory fitness levels were associated with better working memory performance only for males with no such relation observed for females. In addition, the sexually dimorphic pattern was selective for the most challenging working memory conditions in each task. Together, these findings reveal new evidence that cardiorespiratory fitness is selectively related to better working memory performance for male children. This investigation provides additional insight into how interventions aimed at improving fitness may influence cognitive development differentially among preadolescent children. 相似文献

The canonical AX-CPT task measures two forms of cognitive control: sustained goal-oriented control (“proactive” control) and transient changes in cognitive control following unexpected events (“reactive” control). We modified this task by adding negative and neutral International Affective Picture System (IAPS) pictures to assess the effects of negative emotion on these two forms of cognitive control. Proactive and reactive control styles were assessed based on measures of behavior and electrophysiology, including the N2 event-related potential component and source space activation (Low Resolution Tomography [LORETA]). We found slower reaction-times and greater DLPFC activation for negative relative to neutral stimuli. Additionally, we found that a proactive style of responding was related to less prefrontal activation (interpreted to reflect increased efficiency of processing) during actively maintained previously cued information and that a reactive style of responding was related to less prefrontal activation (interpreted to reflect increased efficiency of processing) during just-in-time environmentally triggered information. This pattern of results was evident in relatively neutral contexts, but in the face of negative emotion, these associations were not found, suggesting potential response style-by-emotion interaction effects on prefrontal neural activation. 相似文献

Panentheism has recently become a widely accepted and appreciated concept among scholars in the science-theology dialogue, and its theological repercussions have been discussed to great extent. Yet, there remains to be studied in more detail the notion of the philosophical foundations of the term. A prominent gap in our understanding of these foundations is the potential similarity between the metaphysics of Hegel and Whitehead, their understanding of the transcendence and immanence of God, and their respective versions of panentheism. In this article, I present a critical reflection on the possible resemblance between process thought and Hegelian metaphysics and philosophy of God. In the last section I refer to those who use panentheism within the science-theology dialogue. I try to specify which of the two versions of panentheism, that of Hegel or Whitehead, is more popular among those scholars. 相似文献
