Early Developmental Precursors of Externalizing Behavior in Middle Childhood and Adolescence 总被引:1,自引:0,他引:1
This study examined the infancy- and toddler-age precursors of children's later externalizing problem behavior. Risk constructs included suboptimal patterns of observed caregiver-child interaction and the caregiver's perception of child difficultness and resistance to control. In addition, a novel dimension of caregiver-child relationship quality, the caregiver's perception of her toddler's unresponsiveness to her, was examined as a possible precursor of children's externalizing behavior. Externalizing problem outcomes were assessed throughout the school-age period and again at age 17, using multiple informants. As toddlers, children at risk for later externalizing behavior were perceived as difficult and resistant to control, and relationships with their caregivers were relatively low in warmth and affective enjoyment. Finally, the caregiver's perception of her toddler as emotionally unresponsive to her was a consistent predictor of later externalizing behavior, suggesting that negative maternal cognitions associated with child conduct problems may begin in toddlerhood. These predictive patterns were similar for boys and girls, and with minor exceptions, generalized across different subdimensions of externalizing problem behavior. Our findings underscore the importance of the infancy and toddler periods to children's long-term behavioral adjustment, and indicate the desirability of further research into the nature of caregivers' early perceptions of child unresponsiveness. 相似文献

A mailed survey of female prenatal genetic counselors, obstetric nurses, and high school biology teachers was conducted to determine if these groups hold different attitudes toward genetic risk and to investigate the extent to which any differences result from the effect of different professional experiences. In this study, the participants were 166 genetic counselors, 116 obstetric nurses, and 78 biology teachers (n = 360). Survey participants completed a written questionnaire designed to assess their numeric estimate of the empiric risk for birth defects/genetic problems, their subjective perception of this risk, and their personal use of prenatal diagnosis. Genetic counselors were found to be less likely than the other groups to consider the frequency of birth defects/genetic problems as rare and were 10 times more likely than nurses and 8 times more likely than teachers to have had prenatal diagnosis. Furthermore, more than half of the prenatal diagnosis procedures had by genetic counselors were not medically indicated. These results suggest that genetic counselors have an increased perception of genetic risks relative to nurses or teachers. Possible explanations for this finding are discussed, and the potential role of discordant risk perception in creating biases in the genetic counseling process is explored. 相似文献

Parental Discipline and Externalizing Behavior Problems in Early Childhood: The Roles of Moral Regulation and Child Gender 总被引:4,自引:0,他引:4
We tested whether individual differences in a component of early conscience mediated relations between parental discipline and externalizing behavior problems in 238 3.5-year-olds. Parents contributed assessments of discipline practices and child moral regulation. Observations of children's behavioral restraint supplemented parental reports. Parents and teachers reported on child externalizing symptoms. Parental induction, warm responsiveness, and less frequent use of physical punishment generally were associated with higher levels of moral regulation and fewer externalizing problems. Moreover, moral regulation partially mediated relationships between discipline and externalizing symptoms, with the clearest case of mediation involving induction. However, relationships were found for boys only. Results support a mediation model wherein inductive and physical discipline may influence the expression of boys' externalizing behavior through effects on conscience. Finally, results suggest that different developmental processes may be associated with early externalizing problems in boys and girls, and confirm that fathers' reports contribute to our understanding of the origins of child externalizing problems. 相似文献

The relationship between optimism, abstinence self-efficacy, and self-mastery was examined by investigating levels of these cognitive resources among two samples of recovering substance abusers: Oxford House residents who attended twelve-step groups and twelve-step members who had never lived in an Oxford House. Participants 'levels of optimism were significantly and positively related to both abstinence self-efficacy and self-mastery scores, as abstinence self-efficacy was significantly and positively related to participants' number of days abstinent. Participants who reported having more than 180 days abstinent reported significantly higher levels of abstinence self-efficacy than participants who reported having less than 180 days abstinent. In addition, among participants who reported having less than 180 days abstinent, Oxford House residents reported significantly higher levels of abstinence self-efficacy than twelve-step members. Overall, findings suggest that cognitive resources facilitate substance abusers' recovery and that the Oxford House model might provide high levels of support in their ongoing abstinence. 相似文献

As the Internet has changed communication, commerce, and the distribution of information, so too it is changing psychological research. Psychologists can observe new or rare phenomena online and can do research on traditional psychological topics more efficiently, enabling them to expand the scale and scope of their research. Yet these opportunities entail risk both to research quality and to human subjects. Internet research is inherently no more risky than traditional observational, survey, or experimental methods. Yet the risks and safeguards against them will differ from those characterizing traditional research and will themselves change over time. This article describes some benefits and challenges of conducting psychological research via the Internet and offers recommendations to both researchers and institutional review boards for dealing with them.

Members of disadvantaged groups often report that they are less vulnerable to discrimination than is the average member of their group. In two experiments, we examined how the framing of self-ingroup comparisons moderates this phenomenon. In Experiment 1, participants estimated the relative likelihood that either they, compared to the average member of their ingroup, would experience discrimination or that the average member of their ingroup, compared to themselves, would experience discrimination. In Experiment 2, a direct manipulation of self-ingroup similarity was added to this framing manipulation. Across the experiments, the results demonstrated that conditions highlighting differences between the individual and the group led participants to perceive themselves as much less vulnerable to discrimination than their group, relative to conditions highlighting similarities between the individual and the group. 相似文献

Participant-witnesses viewed a crime video and attempted to identify the culprit from a culprit-absent lineup. The 253 mistaken-identification eyewitnesses were randomly given confirming, disconfirming, or no feedback regarding their identifications. Feedback was immediate or delayed 48 hr, and measures were immediate or delayed 48 hr. Confirming, but not disconfirming, feedback led to distortions of eyewitnesses' recalled confidence, amount of attention paid during witnessing, goodness of view, ability to make out facial details, length of time to identification, and other measures related to the witnessing experience. Unexpectedly, neither delaying the measures nor delaying feedback for 48 hr moderated these effects. The results underscore the need for double-blind lineups and neutral assessments of eyewitnesses' certainty and other judgments prior to feedback. 相似文献

Some of the factors that influence our understanding of the nature of names and words were investigated. Participants (from kindergarten, 2nd, 4th, and 6th grades, and a university undergraduate class) were told a series of brief narratives thematizing the relation between objects and names, after which they were asked questions about the origins and changeability of names and words. Responses were coded as either realist (i.e., viewing names as intrinsic properties of objects) or nominalist (i.e., understanding names and words as arbitrary social conventions). By Grade 2, the children showed a significant increase in nominalist thinking, but this was not a universal development among the participants. Many adults expressed views that did not reflect a strictly nominalist understanding of words and names. Furthermore, the use of nominalist and realist models was influenced by various social-discursive factors including the type of object being named, the type of name being asked about, and the participant's prior experience with the name. It is argued that linguistic (especially literate) experiences play a crucial role in developing a nominalist understanding of names and words. 相似文献

Implicit attitude formation through classical conditioning 总被引:1,自引:0,他引:1
We sought to demonstrate that attitudes can develop through implicit covariation detection in a new classical conditioning paradigm. In two experiments purportedly about surveillance and vigilance, participants viewed several hundred randomly presented words and images interspersed with critical pairings of valenced unconditioned stimuli (USs) with novel conditioned stimuli (CSs). Attitudes toward the novel objects were influenced by the paired USs: In a surprise evaluation task, the CS paired with positive items was evaluated more positively than the CS paired with negative items. This attitudinal conditioning effect was found using both an explicit measure (Experiments 1 and 2) and an implicit measure (Experiment 2). In a covariation estimation task involving the stimuli presented in the conditioning procedure, participants displayed no explicit memory for the pairings. 相似文献
