Activity level (AL) is a highly salient feature of child behaviour that has been linked to developmental outcome. Twin studies of parent‐rated, observer‐rated and mechanically assessed AL in childhood find that AL is genetically influenced. Few studies, however, consider whether different methods of assessing AL have a shared genetic etiology. Those that do, confound methods and situations. The present study examined whether actigraph and rater‐based (parent, observer) measures of AL tap the same genetic influences in a sample of 312 2‐year‐old twin pairs. Methods were studied within the same situation, thereby controlling for situational influences on AL. The genetic correlation between actigraph and parent‐rated AL in the home was .38, indicating modest genetic overlap between the two methods. In contrast, the correlation of genetic effects on actigraph and observer‐rated AL in the laboratory was .95, indicating that both laboratory‐based measures of AL are influenced by the same genetic effects. 相似文献

Complex social stimuli (like faces) can be studied using a methodology typically reserved for studying lights, tones, and
colors: psychophysics. Given that psychophysics examines how humans detect and respond to stimuli in their environment, we
can extend that to the study of how humans detect social stimuli in the environment. Using psychophysical methodology to answer
“social” questions provides another dimension of experimental manipulation and control to the diverse array of methodologies
already used by social psychologists. In this article, we review psychophysical methodology, provide a rationale for social
psychophysics, describe an easy-touse software program called PsychoPro, for collecting psychophysical data, and present data
collected using this program to examine racial thresholds that provide evidence for a cognitive gating mechanism for racial
information that impacts face processing (MacLin & MacLin, 2007, in press; MacLin, MacLin, & Peterson, 2008). 相似文献

Internet addiction is a new and often unrecognized clinical disorder that can cause relational, occupational, and social problems.
Pathological gambling is compared to problematic internet use because of overlapping diagnostic criteria. As computers are
used with great frequency, detection and diagnosis of internet addiction is often difficult. Symptoms of a possible problem
may be masked by legitimate use of the internet. Clinicians may overlook asking questions about computer use. To help clinicians
identify internet addiction in practice, this paper provides an overview of the problem and the various subtypes that have
been identified. The paper reviews conceptualizations of internet addiction, various forms that the disorder takes, and treatment
considerations for working with this emergent client population. 相似文献

Members of high-status groups have been shown to favor social inequality, but little research has investigated the boundary conditions of this phenomenon. In the present article we suggest that perceived intergroup threat moderates the relationship between group status and support for social inequality (i.e., social dominance orientation), especially among highly identified group members. In Study 1, Democrats and Republicans rated their party’s relative status and were later exposed to a leading US. Presidential candidate from the opposing party (high threat) or their own party (low threat). In Study 2, university students were made to believe that their school had high or low status and were then presented with threatening or non-threatening information about a rival institution. The results of both studies supported the prediction that status only increases preferences for group-based inequality under conditions of high threat and high ingroup identification. 相似文献

This repeated measures study examines (1) the change in subjective risk of mutations pre- to postcounseling, (2) the accuracy of BRCAPRO estimates of mutations, and (3) the discrepancy between subjective risk and BRCAPRO estimates of mutations before and after genetic counseling. Ninety-nine Ashkenazi Jewish individuals pursued testing for BRCA1/2 mutations. Most had a personal cancer history (N = 51; family only: N = 48); and received uninformative negative results (N = 66; positives: N = 23; informative negative: N = 10). The coping strategy of defensive pessimism predicts that individuals will believe the worst case scenario to better cope with a potential negative outcome. Consistent with this, most felt they would have a mutation, if not mutations in both genes. The BRCAPRO model appeared to overestimate risk of having a mutation in this sample (p < .001). BRCAPRO overestimates notwithstanding, genetic counseling increased accuracy of subjective risk (p < .01). Individuals with a family-only cancer history had the least accurate estimates of risk (p < .05) and may need further intervention to either manage anxiety or improve knowledge. 相似文献

Do You See What I See? Effects of Group Consciousness on African American Women's Attributions to Prejudice 总被引:1,自引:1,他引:0
Kimberly R. King 《Psychology of women quarterly》2003,27(1):17-30
This study examined the effects of three types of group consciousness among African American women ( ethnic , feminist , and womanist ) on prejudice attributions and appraised personal significance ( centrality ) of a negative intergroup event. African American female college students ( N = 123) imagined themselves in an audiotaped scenario in which they overheard two European American male classmates make negative evaluations of them. The scenario provided no cause for the negative evaluations and no references to race or gender. Multiple regression analyses revealed that higher ethnic and womanist consciousness were related to increased prejudice attributions and greater centrality appraisals ( p <.05) , while feminism had no effect. Results suggest that womanist consciousness may be more relevant than traditional feminist consciousness in predicting African American women's perceptions of prejudice. 相似文献

Concerns regarding American schools and mental health services for children abound, including inadequate educational achievement, school violence, over-referral to special education and disproportionate placement of minorities into special education, under-utilization of mental health services for children, and a poorly coordinated system of child mental health services. All of the above concerns share two common attributes: (a) they are statements regarding populations, rather than specific individuals; and (b) they are best addressed by changing system-wide elements of psychological service delivery. We argue that, although conceptualizing school psychology as primarily an indirect service specialty (e.g., J. Sch. Psychol. 28 (1990) 203) has advanced our thinking about effective service delivery, conceptualizing school psychological services from a public health perspective will provide an even broader framework that can increase both the efficacy and efficiency of school psychologists' work. 相似文献

Evidence for the validity of the Behavior Rating Inventory of Executive Function (BRIEF; Gioia, Isquith, Guy, & Kenworthy, 2000) based on internal structure was examined in a sample of children with mixed clinical diagnoses via maximum likelihood confirmatory factor analysis. Four alternative factor models of children's executive function, based on current theories that posit a unidimensional versus fractionated model (Rabbitt, 1997; Shallice & Burgess, 1991), using the revised 9-scale BRIEF configuration that separates two components of the Monitor scale, were examined for model fit. A 3-factor structure best modeled the data when compared directly with 1-, 2-, and 4-factor models. The 3-factor model was defined by a Behavior Regulation factor consisting of the BRIEF Inhibit and Self-Monitor scales, an Emotional Regulation factor consisting of the Emotional Control and Shift scales, and a Metacognition factor composed of the Working Memory, Initiate, Plan/Organize, Organization of Materials, and Task-Monitor scales. The findings support a fractionated, multi-component view of executive function as measured by the BRIEF. 相似文献

A variety of detrimental effects are associated with early parental loss. We examined the relationship between childhood maternal loss and maternal identity among 30 motherless mothers and their 26 matched controls, as well as the psychological health of their firstborns. Motherless mothers reported significantly lower maternal identity. However, firstborns of motherless mothers were no more likely to display psychological symptoms than firstborns of comparison mothers. The findings suggest that early maternal loss may not present risk for cross-generational effects. 相似文献
