AbstractThis meta-analytic review evaluates 35 parenting programs to analyze their effectiveness at reducing young children’s externalizing behavior (EB). It looks at whether behavioral or cognitive orientation, informant or duration of these programs moderate their effect on such young children. It confirms that parenting interventions are effective at decreasing young children’s EB but no moderation effect was found for specific orientation or duration, only for the informant. This illustrates the current difficulty in comparing programs on the basis of their theoretical background, which prevents the understanding of which are the most efficient parenting variables and change processes to manipulate. 相似文献

Mental retardation is a group of cognitive disorders with a significant worldwide prevalence rate. This high rate, together with the considerable familial and societal burden resulting from these disorders, makes it an important focus for prevention and intervention. While the diseases associated with mental retardation are diverse, a significant number are linked with disruptions in epigenetic mechanisms, mainly due to loss-of-function mutations in genes that are key components of the epigenetic machinery. Additionally, several disorders classed as imprinting syndromes are associated with mental retardation. This review will discuss the epigenetic abnormalities associated with mental retardation, and will highlight their importance for diagnosis, treatment, and prevention of these disorders. 相似文献

With the rapid shifts in the education of women in the United States, and the underrepresentation of women in fields of science, technology, engineering, and math (STEM), an issue generating much controversy is whether women may benefit more from single-sex education or coeducation. The present study surveyed 548 U.S. high-school boys and girls from single-sex and coeducational high-schools from the Midwest. Half of the participants completed a mathematics test under stereotype threat (ST) condition and half under no threat condition. Although girls in single-sex schools had higher achievement motive and self-esteem than those in coeducational schools, they were not more likely to pursue STEM careers. Overall, students in single-sex schools outperformed students from coeducational schools on the math test. Girls?? math performance was significantly higher in the ST condition than in the no threat condition. 相似文献

The vasopressin (VP)/oxytocin (OT)-related peptides constitute a large superfamily found in a wide range of both vertebrate and invertebrate species. While intensive literature reports that these neuropeptides influence behavior, especially learning and memory, in numerous species from diverse vertebrate groups, their roles in behavioral regulation have never been studied in invertebrates. Here, we investigated the role of two VP/OT superfamily peptides, octopressin (OP) and cephalotocin (CT), on long-term memory (LTM) formation of a passive avoidance task in a cephalopod mollusc, the cuttlefish, Sepia officinalis. Subadult cuttlefish were intravenously injected, in a dose range of 3–60 μg/kg, 1 h after the training phase (consolidation design); retention performance was tested 24 h post-training. We found that administration of OP at low dose (3 μg/kg) enhanced LTM, whereas a dose of 60 μg/kg attenuated it. No effect of OP on LTM was observed for the 15 μg/kg dose. Conversely, an enhancement of retention performance was observed at all doses of CT tested. This study is the first to demonstrate the behavioral effects of VP/OT superfamily peptides in an invertebrate species. The valuable role of VP/OT-like peptides on memory processes offers new evolutionary perspectives on peptidergic transmission and neuromodulation. 相似文献

Although the brown lemur (Eulemur fulvus) and the black lemur (Eulemur macaco) share many life parameters and are genetically closed, they show considerable difference in social organization. Dominance relationships with no systematic effect of gender characterize the former, whereas the latter is based on female dominance. The present study was done on two captive groups of brown lemurs and one semi–free‐ranging group of black lemurs. To reveal links between the specific pattern of social organization and agonistic behaviors, agonistic interactions were analyzed for each species as for their context of occurrence, symmetry, initiation, and outcome. The effect of gender in the initiation of conflicts appeared as the only notable interspecific difference, aggression being mostly initiated by females in E. macaco and by males in E. fulvus. Conflict outcome was generally in favor of the initiator, regardless of gender in both species. The analysis of postconflict behaviors revealed conciliatory processes in the brown lemur, whereas reconciliation seemed to be absent in the black lemur, a characteristic shared with the ring‐tailed lemur (Lemur catta), another lemur species with female dominance.

The goal of the current paper is to review the literature on the relationships between perceived control and episodic memory throughout adulthood. More specifically, three major questions are pursued: (1) Are higher levels of perceived control related to better memory performance? (2) Is the relationship between perceived control and memory similar or different as a function of age? (3) Does perceived control moderate memory decline? Although there is a great deal of evidence that perceived control and episodic memory are positively related in adulthood, the current review showed that very few studies have investigated whether age moderated this relationship. Moreover, only a limited number of studies have explored the role of perceived control in memory decline, and the results are inconsistent. We suggest some avenues for future research that could help understand by which mechanisms, and under what circumstances, perceived control and episodic memory are related across the lifespan. 相似文献

It is widely admitted that low self‐efficacy has a detrimental impact on the functioning and performance of a person mainly concerned with performance goals but has no impact when a person is mainly concerned with learning goals (Dweck, 1986 ). However, results from both correlational and experimental studies are divergent. Since these studies examined very few indicators of participants' cognitive functioning, they may have failed to detect those aspects that could be more vulnerable to a negative impact of the combination of performance goals and low self‐efficacy. Another concern is the lack of most studies to clearly distinguish the type of performance goal examined, particularly the performance‐avoidance versus the performance‐approach goal. In the current study, we decided to focus on performance‐approach and learning goals in order to examine how self‐efficacy intervenes in their effects on participants' self‐regulation and performance on a cognitive task. One hundred and forty participants (85 females and 55 males) were examined. They were randomly assigned either to the learning or the performance‐approach goals condition. In each condition, half of the participants received feedback aimed at inducing either high or low self‐efficacy beliefs with regard to the task prior to executing it aloud. Examination of participants' verbal reports, direct observation of some of their behaviours while solving the task, and responses to a retrospective questionnaire allowed the assessment of several indicators of their self‐regulation and performance. As already reported by many studies, self‐efficacy influenced various aspects of participants' self‐regulation and performance. However, contrary to Dweck's hypothesis ( 1986 ), when interaction effects between self‐efficacy and goals were observed, they always involved learning instead of performance‐approach goals. Findings of this study suggest that the nature of the goal might not matter as much as its personal significance or value. 相似文献

This study examined memory functioning in children and adolescents with 22q11.2 Deletion Syndrome (DS; velocardiofacial syndrome). An overall verbal better than nonverbal memory pattern was evident on the Test of Memory and Learning (TOMAL), with children with 22q11.2 DS performing significantly below their siblings and children with low average IQ but similar to children with autism on facial memory. Children with 22q11 DS also performed significantly below their siblings on tests of verbal working memory. Children with autism performed significantly poorer than the siblings of children with 22q11.2 DS only on their recall of stories. Delayed recall was significantly poorer in children with 22q11.2 DS and children with autism, compared to sibling controls. Although there were no significant group differences on tests of multiple trial verbal or visual learning, a relative weakness was noted with multiple trial visual learning in children with 22q11.2 DS and their siblings, suggesting that an alternative or interactive factor other than the deletion may account for the relatively better verbal compared to nonverbal memory abilities. Deficits in facial memory in children with both 22q11.2 DS and autism suggest disruptions in ventral temporal pathways such as between fusiform gyrus and parahippocampal/hippocampal regions whereas deficits in verbal working memory in children with 22q11.2 DS implicates dorsolateral prefrontal regions, both intimating aberrant white matter pathways. 相似文献

In 3 experiments, we investigate how anxiety influences interpretation of ambiguous facial expressions of emotion. Specifically, we examine whether anxiety modulates the effect of contextual cues on interpretation. Participants saw ambiguous facial expressions. Simultaneously, positive or negative contextual information appeared on the screen. Participants judged whether each expression was positive or negative. We examined the impact of verbal and visual contextual cues on participants' judgements. We used 3 different anxiety induction procedures and measured levels of trait anxiety (Experiment 2). Results showed that high state anxiety resulted in greater use of contextual information in the interpretation of the facial expressions. Trait anxiety was associated with mood-congruent effects on interpretation, but not greater use of contextual information. 相似文献

Faces from another race are generally more difficult to recognize than faces from one's own race. However, faces provide multiple cues for recognition and it remains unknown what are the relative contribution of these cues to this “other-race effect”. In the current study, we used three-dimensional laser-scanned head models which allowed us to independently manipulate two prominent cues for face recognition: the facial shape morphology and the facial surface properties (texture and colour). In Experiment 1, Asian and Caucasian participants implicitly learned a set of Asian and Caucasian faces that had both shape and surface cues to facial identity. Their recognition of these encoded faces was then tested in an old/new recognition task. For these face stimuli, we found a robust other-race effect: Both groups were more accurate at recognizing own-race than other-race faces. Having established the other-race effect, in Experiment 2 we provided only shape cues for recognition and in Experiment 3 we provided only surface cues for recognition. Caucasian participants continued to show the other-race effect when only shape information was available, whereas Asian participants showed no effect. When only surface information was available, there was a weak pattern for the other-race effect in Asians. Performance was poor in this latter experiment, so this pattern needs to be interpreted with caution. Overall, these findings suggest that Asian and Caucasian participants rely differently on shape and surface cues to recognize own-race faces, and that they continue to use the same cues for other-race faces, which may be suboptimal for these faces. 相似文献
