Loss of control (LOC) eating in youth is associated cross-sectionally with eating-related and psychosocial distress and is predictive of excessive weight gain. However, few longitudinal studies have examined the psychological impact and persistence of pediatric LOC eating. We administered the Eating Disorder Examination and self-reported measures of depressive and anxiety symptoms to 195 boys and girls (mean age = 10.4 years, SD = 1.5) at baseline and again 4.7 years (SD = 1.2) later to 118 of these youth. Missing data were imputed. Baseline report of LOC was associated with the development of partial- or full-syndrome binge eating disorder (p = .03), even after accounting for the contribution of sex, race, baseline characteristics (age, disordered eating attitudes, and mood symptoms), body mass index growth between baseline and follow-up, and years in study. Half (52.2%; 95% CI [1.15, 6.22]) of children who endorsed experiencing LOC at baseline reported persistence of LOC at follow-up (p = .02). Compared with children who never reported LOC eating or reported LOC only at baseline, those with persistent LOC experienced significantly greater increases in disordered eating attitudes (ps < .001) and depressive symptoms (p = .027) over time. These data suggest that LOC eating in children is a problematic behavior that frequently persists into adolescence and that persistent LOC eating is associated with worsening of emotional distress. 相似文献

Visual recognition memory was examined in a group of profoundly retarded young children whose visual-motor developmental level was estimated to be below one year. The children were tested for recognition of a previously shown face photo or a previously exposed color either immediately or following a short-term delay by observing the distribution of their visual fixation responses to novel stimuli when paired with previously seen targets. During a study or “familiarization” period the profoundly retarded children devoted voted approximately the same amount of attention to photos of faces as they did to colored, abstract patterns, and individual differences in overall looking time proved to be reliable. During the recognition testing phase the profoundly retarded children demonstrated immediate recognition memory for both faces and colors, preferring a novel to a previously exposed target, but responsiveness to novelty declined abruptly over a short-term delay, providing little evidence for delayed recognition. 相似文献

This experiment investigated speed of processing the grammaticality of phrases consisting of the adjective “one” or “two” followed by a singular or plural noun. The subject’s task was to press one of two keys, depending upon whether the phrase was grammatically correct or incorrect. There were eight types of phrases, formed by the factorial combinations of singular or plural adjectives, singular or plural nouns, and high or low noun imageD’. These served as within-subjects variables. Between-subjects variables were the factorial combinations of sex of subject, duration of stimulus phrase (.2 or 2.5 sec), and hand assigned to the correct-grammar key. A fourth between-subjects variable was whether or not the subject reported using an artificial phrase-scanning strategy to determine grammaticality. Correct grammar, singular noun form, high noun imagery, and reported use of the strategy all produced highly significant reductions in reaction times. Only 1% of the interactions were significant. A multistage serial processing model that could be based upon Sternberg’s additive factor paradigm or even Donders’ subtraction method was found to be highly successful in describing the results. 相似文献

Two differential eyelid conditioning studies employed grammatically correct and incorrect adjective-noun phrases as conditioned stimuli. For different groups of subjects, the nouns were either high or low in imagery. The hypothesis that congruency between grammatical correctness and reinforcement consequences (i.e., the aversive stimulus contingent upon presence of incorrect rather than correct grammar) would facilitate conditioned discrimination was not supported, but the hypothesis that high noun imagery would facilitate differential response to syntax received strong support. Cognitive awareness of the syntactic discriminandum was also related to effective differential responding, as well as being implicated as a mediating mechanism in the imagery effects. Finally, performance was also significantly related to conditioned-response topography, with better conditioned discrimination by voluntary-form (V) than by conditioned-form (C) responders, and also evidence of more effective utilization of contingency awareness by Vs than by Cs. 相似文献

Two experiments tested the hypothesis that children at the left of the distribution of right minus left (R-L) hand skill are at risk for poor phonological processing. In the first experiment, individual assessments of spoken rhyme awareness were made in 5- to 8-year-olds. In the second experiment, a group test of word order memory for spoken confusable and nonconfusable items was given to 9- to 11-year-olds. Evidence of poorer phonological processing in those at the left of the R-L distribution was found in both experiments. Rhyme judgements and word order memory were both associated with reading ability, but reading did not interact with effects for hand skill. A group test of homophone comprehension was given to the same children tested for word order memory. Homophone errors did not differ between hand skill groups, showing a dissociation between the two tasks for R-L hand difference. The findings suggest that some risks for phonological processing could be due to normal genetic variation associated with the hypothesized rs + gene (Annett, 1972, 1978). 相似文献

Summary The relative strengths of association of imagery, language, and metamemory to cross-modal transfer were evaluated in 5-year-olds and 7-year-olds. Children were administered either tactual-visual or visual-tactual cross-modal transfer tasks, as well as two visual imagery tasks (spatial recall and mental rotation), two language competence tasks (vocabulary and word usage), metamemory questions, and a general intelligence task. With intelligence and handedness controlled, only visual imagery related significantly to cross-modal transfer. These findings suggest that mental imagery, as opposed to language competence or metamemory, is a principal component of cross-modal transfer, and they are consistent with the observation that preverbal human infants and infrahuman primates exhibit cross-modal transfer. 相似文献
