Over the past 30 years researchers have learned a great deal about the development of object processing in infancy. In contrast, little is understood about the neural mechanisms that underlie this capacity, in large part because there are few techniques available to measure brain functioning in human infants. The present research examined the extent to which near-infrared spectroscopy (NIRS), an optical imaging technique, could be used to assess the relation between object processing and brain functioning. Infants aged 6.5 months were presented with an occlusion event involving objects that differed on many feature dimensions (multi-featural change), differed on shape only (shape change) or color only (color change), or did not differ (control). NIRS data were collected in the occipital and inferior temporal cortex. In the occipital cortex, a significant increase in oxyhemoglobin (HbO(2)) was observed in response to all four events and these responses did not differ significantly from each other. In the inferior temporal cortex, a significant increase in HbO(2 )was observed in the multi-featural and the shape change condition but not in the control condition. An increase was also observed in the color change condition but this increase did not differ significantly from baseline nor did it differ significantly from the response obtained in the control condition. These data were discussed in terms of (a) what they suggest about the neural basis of feature processing in infants and (b) the viability of using NIRS to study brain-behavior relations in infants. 相似文献

The Tuskegee Syphilis Experiment (TSE) has shaped African Americans' views of the American health care system, contributing to a reluctance to participate in biomedical research and a suspicion of the medical system. This essay examines public discourses surrounding President Clinton's attempt to restore African Americans' trust by apologizing for the TSE. Through a narrative reading, we illustrate the failure of this text as an attempt to reconcile the United States Public Health Service and the African American public. We conclude by noting the limitations of rhetoric when equal prominence is not given to policy proposals in national apologies. 相似文献

Research consistently shows that children exposed to interparental conflict are at-risk for experiencing psychopathology.
Establishing a link, however, between interparental conflict and maladjustment is not the same as understanding how specific outcomes manifest. Therefore, we examined the relation of interparental conflict and appraisal with adolescent outcome
with 169 high school students (ages 14–19 years). Specifically, threat and self-blame appraisals were hypothesized to mediate
the relation between interparental conflict and both adaptive and maladaptive outcomes. Results suggest that threat partially
mediated the relation between interparental conflict and externalizing problems, interparental conflict and internalizing
problems, and interparental conflict and adaptive behaviors. Additionally, self-blame appears to partially mediate the relation
between interparental conflict and internalizing problems. Implications of the current findings are discussed. 相似文献

Functional analyses identified children whose inappropriate mealtime behavior was maintained by escape and adult attention. Function‐based extinction procedures were tested individually and in combination. Attention extinction alone did not result in decreases in inappropriate mealtime behavior or a significant increase in acceptance. By contrast, escape extinction alone resulted in a decrease in inappropriate mealtime behavior and an increase in acceptance. However, inappropriate mealtime behavior did not decrease to clinically acceptable levels. A combined extinction technique (i.e., escape and attention extinction) resulted in a decrease in inappropriate mealtime behavior to clinically acceptable levels and high and stable acceptance. 相似文献

Activity schedules are often used to facilitate task engagement and transition for children with autism. This study evaluated whether conditional discrimination training would serve to transfer the control from activity‐schedule pictures to printed words (i.e., derived textual control). Two preschoolers with autism were taught to select pictures and printed words given their dictated names. Following training, participants could respond to printed words by completing the depicted task, match printed words to pictures, and read printed words without explicit training (i.e., emergent relations). 相似文献

Health anxiety (HA) involves persistent worry about one’s health and beliefs one has an illness or may contract a disease. In the present study, gender differences in Noyes et al.’s (2003) interpersonal model of health anxiety (IMHA) were examined. Using a sample of 950 undergraduates (674 women; 276 men), multigroup confirmatory factor analyses suggested the measurement model for key dimensions of the IMHA (i.e., reassurance-seeking, alienation, worry, and absorption) were invariant across gender. This suggests key dimensions of this model are applicable to and generalizable across women and men. Coefficients alpha for and bivariate correlations between these IMHA dimensions were also roughly comparable across women and men. As hypothesized, mean levels of reassurance-seeking and worry were significantly higher in women compared to men. No gender differences were observed in mean levels of alienation or absorption. Reassurance-seeking and worry appear salient in the interpersonal behavior and emotional life of women with HA. The present study helps to clarify gender differences in the IMHA and other HA models involving similar variables. 相似文献

Two studies examined correlates of the Narrative Emplotment Scale (NES), which measures the extent to which individuals perceive chance events and unchosen experiences as meaningfully connected. In Study 1 (N=99), the NES demonstrated adequate test–retest stability and good internal reliability. The scale was positively related to paranormal beliefs, mystical experiences, and absorption. In Study 2 (N=342), personality measures indicative of external locus of control, intrinsic religiosity, well‐being, satisfaction with life, and a measure of frequency of coincidence experience were all positively correlated with narrative emplotment, providing further support for the construct validity of the scale. In terms of the question of whether meaning making is predictive of better or worse psychological adjustment, analyses indicated that the relationship between narrative emplotment and psychological adjustment was moderated by individual differences in coping strategies. Path analysis indicated that emplotment was a mediator of the pathway between religiosity and well‐being. Emplotment had a negative effect on well‐being through chance locus of control. These analyses suggest that this type of meaning‐making is an important variable for understanding religious/spiritual beliefs and their influence on psychological adjustment. 相似文献

Laboratory studies have shown considerable differences between the eating behavior, particularly binge eating behavior, of participants with and without binge eating disorder (BED). However, these findings were not replicated in two field experiments employing ecological momentary assessment (EMA) in which obese BED and obese non-BED participants reported comparable binge eating behavior. In the current study, we examined differences in binge eating with an innovative assessment scheme employing both EMA and a standardized computer-based dietary recall program to avoid some of the limitations of past laboratory and field research. Obese BED, obese non-BED, and non-obese control participants reported significant differences in eating patterns, loss of control, overeating, and binge eating behavior. Of particular importance was the finding that BED participants engaged in more overeating and more binge eating episodes than non-BED participants. These findings suggest that the use of EMA in combination with dietary recall may be a relatively objective and useful approach to assessing binge eating behavior. The findings further suggest that individuals with BED are observably different from those without the disorder, which may have implications for eating disorder diagnoses in DSM-V. 相似文献

One hundred alleged victims of child sexual abuse (aged 4–13; M = 9.3 years) were interviewed by police investigators about their alleged experiences. Half of the children were interviewed using the National Institute of Child Health and Human Development (NICHD) structured interview Protocol, whereas the other children, matched with respect to their age, relationship with the alleged perpetrator, and seriousness of the alleged offenses, were interviewed by investigators following the Memorandum of Good Practice. Protocol‐guided interviews elicited more information using free‐recall invitations and less information using directive, option‐posing and suggestive questions than did standard Memorandum interviews. There were no age differences in the proportion of total information provided in response to open‐ended invitations in either condition, but there was a significant increase with age in the proportion of central information provided in response to open‐ended invitations.

Is synaesthesia cognitively useful? Individuals with time–space synaesthesia experience time units (such as months of the year) as idiosyncratic spatial forms, and report that these forms aid them in mentally organising their time. In the present study, we hypothesised that time–space synaesthesia would facilitate performance on a time-related cognitive task. Synaesthetes were not specifically recruited for participation; instead, likelihood of time–space synaesthesia was assessed on a continuous scale based on participants’ responses during a semi-structured interview. Participants performed a month-manipulation task, which involved naming every second month or every third month in reverse-chronological order, beginning and ending with a target month. Using hierarchical multiple regression, we found that time–space synaesthesia corresponded with faster performance on both versions of the task. We propose that time–space synaesthesia may expedite the cognitive manipulation of time-based information. Our results also indicate that synaesthesia is far less unusual than widely believed. 相似文献
