Two domains of potential risk in relation to the cognitive-linguistic outcomes of preschool children of adolescent mothers were investigated: (1) interactive features of the mother—child relationship and (2) aspects of the demographic context of parenting. Sixty-nine adolescent mothers and their children participated in evaluations when the children were 13, 20, 30, and 44 months old. Results indicated that the cognitive-linguistic development of children of adolescent mothers was affected by both the mother—child relationship and cumulative index of demographic risk. Specifically, positive maternal affect, mother—child verbal reciprocity, mother—child interactive fit, and cumulative demographic risk all contributed to explaining difficulties in preschool cognitive and linguistic functioning in children of adolescent mothers. 相似文献

Visual similarity effects in immediate verbal serial recall 总被引:4,自引:0,他引:4

The role of visual working memory in temporary serial retention of verbal information was examined in four experiments on immediate serial recall of words that varied in visual similarity and letters that varied in the visual consistency between upper and lower case. Experiments 1 and 2 involved words that were either visually similar (e.g. fly, cry, dry; hew, new, few ) or were visually distinct (e.g. guy, sigh, lie; who, blue, ewe ). Experiments 3 and 4 involved serial recall of both letter and case from sequences of letters chosen such that the upper- and lower-case versions were visually similar, for example Kk, Cc, Zz, Ww , or were visually dissimilar, for example Dd, Hh, Rr, Qq . Hence in the latter set, case informationwas encoded interms of both the shape and the size of the letters. With both words and letters, the visually similar items resulted in poorer recall both with and without concurrent articulatory suppression. This visual similarity effect was robust and was replicated across the four experiments. The effect was not restricted to any particular serial position and was particularly salient in the recall of letter case. These data suggest the presence of a visual code for retention of visually presented verbal sequences in addition to a phonological code, and they are consistent with the use of a visual temporary memory, or visual "cache", in verbal serial recall tasks. 相似文献

AbstractIn the present study, the relation between children’s emotion knowledge and preschool teachers’ book reading behaviors during shared book reading in the classroom was examined. A new coding system, the Book Readings for an Affective Classroom Education (BRACE), was developed to capture teachers’ macro-level book reading behaviors (i.e., dialogic reading) and micro-level use of emotion language (i.e., emotion coaching) during shared book reading. Results showed good reliability and validity of the BRACE. Further, teachers’ dialogic reading and emotion coaching behaviors during shared book reading positively predicted child emotion knowledge in Spring (T2), after controlling for children’s initial level of emotion knowledge in Fall (T1). In addition, a significant interaction between teachers’ book reading style and child emotion knowledge at T1 on emotion knowledge at T2 indicated that teachers’ effective book reading style was especially beneficial to children who had lower emotion knowledge at the beginning of the school year. 相似文献

Using a prospective research design, this study explored whether attachment style during adolescence forecasts the nature and quality of romantic relationships in early adulthood and investigated two general pathways for explaining these effects. Black and White community residents were first interviewed in adolescence at which time they completed a self-report measure of attachment style. Approximately 6 years later, they participated in a follow-up interview along with their current romantic partners (N = 224 couples). Results revealed that insecure attachment in adolescence was a risk factor for adverse relationship outcomes in adulthood, although the effects were most consistent for avoidant attachment. Avoidant adolescents were involved in relationships that they (and their partners) rated as less satisfying overall; they also engaged in fewer pro-relationship behaviors, and perceived that their partners engaged in fewer pro-relationship behaviors. In addition, avoidant adolescents were involved with partners who had less healthy personality profiles. Results for anxious-ambivalent and secure attachment were weaker, more complex, and moderated by gender. This study provides the first prospective evidence that avoidant attachment places individuals at risk for adverse relationship outcomes and highlights potential pathways through which this occurs. 相似文献

Prospective and retrospective memory in normal aging and dementia: an experimental study 总被引:4,自引:0,他引:4
Two experiments investigated the effects of normal aging and dementia on laboratory-based prospective memory (PM) tasks. Participants viewed a film for a later recognition memory task. In Experiment 1, they were also required either to say "animal" when an animal appeared in the film (event-based PM task) or to stop a clock every 3 min (time-based PM task). In both tasks, young participants were more successful than older participants, who were, in turn, more successful than patients with Alzheimer's disease (AD). For successful remembering in the time-based task, older participants and AD patients checked the clock more often than did young participants. In Experiment 2, participants were asked to reset a clock either when an animal appeared in the film (unrelated cue-action) or when a clock appeared in the film (related cue-action). Responses were faster in the related condition than in the unrelated condition. Again, there were differences in PM performance between young and older participants, and between older participants and AD patients. The observed deficits were not due to the forgetting of the PM task instructions in either experiment. Retrospective memory (RM) tasks (digit span, sentence span, free recall, and recognition) were more impaired by AD than were the PM tasks. Factor analysis revealed separate factors corresponding to RM and PM. 相似文献

Current neuropsychological models propose that some age-related cognitive changes are due to frontal-lobe deterioration. However, these models have not considered the possible subdivision of the frontal lobes into the dorsolateral and ventromedial regions. This study assessed the age effects on 3 tasks of executive function and working memory, tasks dependent on dorsolateral prefrontal dysfunction; and 3 tasks of emotion and social decision making, tasks dependent on ventromedial prefrontal dysfunction. Age-related differences in performance were found on all tasks dependent on dorsolateral prefrontal dysfunction. In contrast, age-related differences were not found on the majority of the tasks dependent on ventromedial prefrontal dysfunction. The results support a specific dorsolateral prefrontal theory of cognitive changes with age, rather than a global decline in frontal-lobe function. 相似文献

Research in education, psychology, and neuroscience motivates a hypothesis that learning takes time. Support for the hypothesis was found in four replications of an upper level undergraduate course in which the material and activities for 50% of the topics were delivered over the World-Wide Web. Computer records were correlated with three types of test questions: multiple-choice, short-answer, and open-ended essay questions. Positive and significant correlations with time were observed for 33% of the correlations involving multiple-choice questions, 13% of those involving short-answer questions, and 60% of those involving open-ended essay questions. An estimate of the common underlying correlation, ρ, equal to .35 for the four replications was significant. The data also revealed generally low overall study times and a maladaptive pattern of “cramming” before tests instead of distributing practice. In the Discussion section, we argue that computer study times can be used as a predictor of subsequent test performance, which is a measure of student learning. 相似文献

It is a common problem in psychology subject pools for past study participants to inform future participants of key experimental details (also known as crosstalk). Previous research (Edlund, Sagarin, Skowronski, Johnson, & Kutter, 2009) demonstrated that a combined classroom and laboratory treatment could significantly reduce crosstalk. The present investigation tested a laboratory-only treatment for the prevention of crosstalk at five universities, along with institutional-level moderators of crosstalk. Results indicated the presence of crosstalk at all universities and that the laboratory-based treatment was effective in reducing crosstalk. Importantly, crosstalk rates were higher (but successfully neutralized) in research pools with higher research credit requirements. Therefore, this research provides valuable guidance regarding crosstalk prevalence and its minimization by researchers. 相似文献

The activation of motivational systems by stimuli in the environment that are associated with rewarding experiences is able to trigger plastic changes in the brain, thereby altering the attentional priority of those stimuli. As a result, attentional deployment is often abnormal in addiction, with drug-related stimuli attracting attention automatically and gaining control over behavior. For example, smokers show attentional biases toward smoke-related cues, but the mechanisms underlying these effects and the nature of their link to addiction are still debated. Here, we investigated the influence of gender and individual factors on the temporal dynamics of attentional deployment toward smoke-related stimuli in young smokers. Crucially, we found a striking gender difference, with only males exhibiting a typical attentional bias for smoke-related items, and the bias revealed strong time dependency. Additionally, for both males and females, various personality traits and smoking habits predicted the direction and strength of the measured bias. Overall, these results unveil a crucial influence of several predictors—notably, gender—on the biases of attention toward smoke-related items in chronic smokers. 相似文献

Functional mapping of left parietal areas involved in simple addition and multiplication. A single‐case study of qualitative analysis of errors 下载免费PDF全文

All electrostimulation studies on arithmetic have so far solely reported general errors. Nonetheless, a classification of the errors during stimulation can inform us about underlying arithmetic processes. The present electrostimulation study was performed in a case of left parietal glioma. The patient's erroneous responses suggested that calculation was mainly applied for addition and a combination of retrieval and calculation was mainly applied for multiplication. The findings of the present single‐case study encourage follow up with further data collection with the same paradigm. 相似文献
