The fact that a perceptual experience akin to the familiar wagon-wheel illusion in movies and on TV can occur in the absence of stroboscopic presentation is intriguing because of its relevance to visuo-temporal parsing. The wagon-wheel effect in continuous light has also been the source of considerable misunderstanding and dispute, as is apparent in a series of recent papers. Here we review this potentially confusing evidence and suggest how it should be interpreted. 相似文献

This study compared the RT3 Research Tracker accelerometer and the Tritrac R3D accelerometer in a field setting. A six-day backpacking expedition (122.4 km in length) was completed by a single subject in the Grand Canyon National Park, Arizona. The overall correlation between the counts of vector magnitude activity for the RT3 and R3D was moderate (r =.75, p<.001), with the overall calculated bias [mean difference (RT3 minus R3D) and standard deviation of the differences] across all six days estimated at 235+/-436 vector magnitude activity counts. However, agreement between the instruments is problematic; the RT3 might be 201 activity counts below or 671 activity counts above the R3D in assessing physical activity during backpacking. 相似文献

The fact that early lexical and grammatical acquisition are strongly correlated has been cited as evidence against the view that the language faculty is composed of dissociable and autonomous modules (Bates & Goodman, 1997). However, previous studies have not yet eliminated the possibility that lexical-grammar associations may be attributable to language-general individual differences (e.g. children who are good at learning words are good at learning grammar). Parent report assessments of toddlers who are simultaneously learning English and Spanish (n = 113) allow an examination of the specificity of lexical-grammar relationships while holding child factors constant. Within-language vocabulary-grammar associations were stronger than cross-language relationships, even after controlling for age, proportion of language exposure, general language skill and reporter bias. Similar patterns were found based on naturalistic language samples (n = 22), ruling out a methodological artifact. These results are consistent with the view that grammar learning is specifically tied to lexical progress in a given language and provide further support for strong lexical-grammatical continuity early in acquisition. 相似文献

The impact of postnatal depression on a child's risk for violent behavior was evaluated in an urban British community sample (N=122 families). Mothers were interviewed during pregnancy, at 3 months postpartum, and when the child was 1, 4, and 11 years of age. Mothers, teachers, and children reported on violent symptoms at age 11. Structural equation modeling revealed that the child's violence was predicted by the mother's postnatal depression even when her depression during pregnancy, her later history of depression, and family characteristics were taken into account. Violence was associated with symptoms of attention-deficit/hyperactivity disorder and problems with anger management. Children were most violent if mothers had been depressed at 3 months and at least once thereafter. 相似文献

A daily diary study examined how chronic perceptions of a partner's regard affect how intimates interpret and respond to daily relationship stresses. Spouses each completed a diary for 21 days. Multilevel analyses revealed that people who felt less positively regarded read more into stressful events than did people who felt highly regarded, feeling more hurt on days after acute threats, such as those posed by a moody or ill-behaved partner. Intimates who felt less valued responded to feeling hurt by behaving badly toward their partner on subsequent days. In contrast, intimates who felt more valued responded to feeling hurt by drawing closer to their partner. Ironically, chronically activated needs for belongingness might lead people who are trying to find acceptance to undermine their marriage. 相似文献

Genetic counseling and the many roles a genetic counselor must assume to provide quality genetic health care are becoming increasingly complex, especially when the genetic condition is rare, and DNA testing is costly and not yet routinely used. A case study of a couple with a family history of retinoblastoma and their pursuit of DNA testing for prenatal diagnosis is presented. The case study illustrates the instrumental role of the genetic counselor in advocating for clients for genetic services such as DNA testing and in educating insurance companies in the nature and importance of such services to achieve improved client health care outcomes. 相似文献

Actions that do not have as their goal the advancement or protection of one's material interests are often seen as illegitimate. Four studies suggested that moral values can legitimate action in the absence of material interest. The more participants linked sociopolitical issues to moral values, the more comfortable they felt advocating on behalf of those issues and the less confused they were by others' advocacy (Studies 1 and 2). Crime victims were perceived as being more entitled to claim special privileges when the crime had violated their personal moral values (Studies 3 and 4). These effects were strongest when the legitimacy to act could not already be derived from one's material interests, suggesting that moral values and material interest can represent interchangeable justifications for behavior. No support was found for the possibility that attitude strength explained these effects. The power of moralization to disinhibit action is discussed. 相似文献
