We investigated ADHD symptoms and CU traits as predictors of violent media use in adolescence, controlling for delinquency and ODD symptoms. The effects on of disinhibition and arousal to negative stimuli, core characteristics of ADHD symptoms and CU traits, and of gender were investigated. At age 15, 88 adolescents, 50 % boys reported on CU traits, ADHD symptoms and delinquency. Parents rated the adolescents’ CU traits, ADHD‐ and ODD symptoms. At age 16, adolescents reported on their media habits and performed tests of disinhibition and arousal to negative stimuli. Boys had higher levels of CU traits and violent media use and girls had higher levels of arousal to negative pictures. CU traits and inattention symptoms predicted violent media use, the latter association applying only to boys, with CU traits being the strongest predictor. Low arousal to threat pictures explained variance in violent media use, above CU traits. Attraction to violent media seems affected by problem behaviors, with CU traits coming forth as especially important. 相似文献

Bullying was investigated as a group process, a social phenomenon taking place in a school setting among 573 Finnish sixth-grade children (286 girls, 287 boys) aged 12–13 years. Different Participant Roles taken by individual children in the bullying process were examined and related to a) self-estimated behavior in bullying situations, b) social acceptance and social rejection, and c) belongingness to one of the five sociometric status groups (popular, rejected, neglected, controversial, and average). The Participant Roles assigned to the subject were Victim, Bully, Reinforcer of the bully, Assistant of the bully, Defender of the victim, and Outsider. There were significant sex differences in the distribution of Participant Roles. Boys were more frequently in the roles of Bully, Reinforcer and Assistant, while the most frequent roles of the girls were those of Defender and Outsider. The subjects were moderately well aware of their Participant Roles, although they underestimated their participation in active bullying behavior and emphasized that they acted as Defenders and Outsiders. The sociometric status of the children was found to be connected to their Participant Roles. © 1996 Wiley-Liss, Inc. 相似文献

The aim of this study was to assess individual and social antecedents of attachment security and attachment disorganization of infants as assessed by the Strange Situation. Observations from two longitudinal studies, with a parallel assessment schedule yielding a total sample of 88 infant-mother pairs, formed the database of the study. Newborn behavioral organization, in terms of orienting ability and regulation of state, and maternal sensitivity assessed several times during the infant's first year were used to predict the security of infant-mother attachment and the status of disorganization of attachment behavior strategies at the age of 12 months. Whereas attachment security was significantly associated only with maternal sensitivity, the status of disorganization was only predicted by newborn behavioral organization. The findings are discussed with respect to specific assumptions about individual and social contribution to the development of infant-mother attachment on the background of maternal attachment representation. 相似文献

The present studies examined the reliability and validity of the Preference Test (PT), a widely used self-report index of preferred hemisphere thinking styles. The PT consists of items that intend to tap left-hemisphere and right-hemisphere cognitions. In the first study (N=47), PT scores were found to have reasonable test–retest stability. In the second study (N=334), a factor analysis of PT scores showed that the PT has a two-factor solution that can best be interpreted in terms of putative left- and right-hemisphere items. In the third study (N=29), background EEG activity (F3, F4, P3 and P4) of subjects was recorded. PT scores were found to be related to EEG asymmetry patterns for frontal, but not for parietal, recording sites. More specifically, subjects with a left-hemisphere preference displayed relatively stronger left frontal activity than subjects with a right-hemisphere preference. By and large, the present findings provide strong support for the reliability and some suggestive evidence for the validity of the PT. 相似文献

Cognitive deficits in major depression 总被引:4,自引:0,他引:4

Major depression is a mood disorder that is often accompanied by the impairment of cognitive functions. Although suggestive, the large range of existing neuropsychological, neuropsychiatric, and, lately, neuroimaging investigations have not yet given a consistent picture of the psychological and biological disturbances involved in this psychiatric disorder. The present study of the cognitive functions in depression was part of an extensive investigation, including neuropsychological testing, psychiatric examination, and neuroimaging. A representative sample of 40 severely depressed hospitalized patients and a group of 49 closely matched control subjects were tested with an extensive neuropsychological test battery. Results, corrected for various confounding factors, confirmed the current notion that depressed patients suffer from wide-spread cognitive impairments. The group analysis did not allow any hypothesis on a possible pattern to the dysfunctions, but heterogeneity in the test performances calls for further analysis of the data in patient subgroups in relation to neuroimaging results. 相似文献

Attachment theorists assume that maternal mental representations influence responsivity, which influences infant attachment security. However, primary studies do not support this mediation model. The authors tested mediation using 2 mother-infant samples and found no evidence of mediation. Therefore, the authors explored sensitivity as a moderator, studying the (a) interaction of mental representation and sensitivity as it predicts infant attachment security and (b) level of sensitivity in mothers whose infants' attachment security is either concordant or discordant with their own. The interactional analyses were not significant. But the match-mismatch data showed that when mother-infant attachment strategies were discordant, maternal sensitivity was more consistent with infant than maternal attachment strategy. These findings are congruent with an interpretation of sensitivity as a moderator that can block transmission of attachment strategy. 相似文献

Six schools were randomly assigned to a multilevel bullying intervention or a control condition. Children in Grades 3-6 (N=1,023) completed pre- and posttest surveys of behaviors and beliefs and were rated by teachers. Observers coded playground behavior of a random subsample (n=544). Hierarchical analyses of changes in playground behavior revealed declines in bullying and argumentative behavior among intervention-group children relative to control-group children, increases in agreeable interactions, and a trend toward reduced destructive bystander behavior. Those in the intervention group reported enhanced bystander responsibility, greater perceived adult responsiveness, and less acceptance of bullying/aggression than those in the control group. Self-reported aggression did not differ between the groups. Implications for future research on the development and prevention of bullying are discussed. 相似文献

Developmental Differences in Metacognition and their Connections with Cognitive Development in Adulthood 总被引:1,自引:0,他引:1
This study investigated developmental differences in some metacognitive variables in ill-defined problem solving and their
possible connections with cognitive development in adulthood. Participants were 57 individuals of different ages (adolescents,
young adults, mature adults and older adults). They solved one well-defined and six ill-defined problems while their thinking-aloud
was taped. They then answered a metacognitive statements questionnaire. Differences in performance were statistically significant
in all problems: the best results in interpolation and divergent production problems were achieved by the younger adult group
and the best performance on most dialectical everyday problems was found in the mature adults' group. We found no significant
differences between age groups in the on-line monitoring of the solving process. Accuracy in metacognitive statements was
however significantly better in the mature adult and the younger adult groups. Awareness of and reflection on one's own mental
processes showed a similar developmental pattern to relativistic/dialectical thought: low expression in adolescence, an increase
in early adulthood, a peak in mature adulthood and a minor decline in later years. 相似文献

To investigate the contested role of notional number in English subject-verb agreement, we used a sentence completion task
to examine agreement with minimally different subject noun-phrases, such as the gang on the motorcycles and the gang near
the motorcycles. These contrasting phrases biased different notional construals of collective nouns, such as gang, which are
normally ambiguous between plural (distributed) and singular (collected) construals. With subjects biased toward spatial distribution,
such as gang on motorcycles, more plural verbs occurred in speakers’ sentence completions than in sentence completions with
a bias toward spatial collection such as gang near motorcycles. This offers strong evidence regarding both the existence and
the magnitude of notional effects on subject-verb number agreement in English. 相似文献
