Piaget suggests that animistic thinking is a pervasive feature of children's cognition. To test this notion, 4- to 8-year-old children were shown several inanimate objects and asked to pick those which perform activities characteristic of living organisms. These activities were typified by six verbs: eat, sleep, breathe, grow, die,, and be alive. Fifty percent of the younger children responded animistically, by misattributing life processes to inanimate objects, but only 18% of their total responses were animistic. Twenty percent of the older children responded animistically, but only 20% of their responses were animistic. In Experiment II, children were shown drawings singly and asked if the object could perform activities named by one of the six verbs. Results were similar to those of Experiment I but with somewhat less animism. Experiment III required children to spontaneously name things that are alive. There were no animistic responses. It was concluded that animistic thinking is not a genuine phenomenon but linguistic confusion elicited by novel objects and unfamiliar words.This work was supported by NSF Grant GB 23083.A portion of the data of Experiment I constituted a Bachelor Honors Thesis conducted by the first author under the direction of the second and submitted to Florida State University. These data were presented at the meeting of the Southeastern Psychological Association, New Orleans, April 1973. 相似文献

This article examines adolescent girls' weightloss behaviors and possible parent influences related toweight and shape. Questionnaires were completed by 369grade 10 girls and their parents. Findings suggested that parent encouragement to loseweight was a more significant predictor of daughterdietary restraint than parents' own dietary restraintlevels. Mother influence variables added significantly to a regression equation after fatherinfluences had been entered, but the reverse was not thecase. Parents' food abstaining behaviors, such asfasting and skipping meals, predicted food abstaining in daughters. Most findings were replicated whendaughter body size was controlled for. Implications formodels of the transmission of diet and weight-relatedvalues from parent to child are discussed. 相似文献

We examined 2-year recall of reports of lifetime symptomatology and substance use questions on the K-SADS-E in a sample of offspring at high and low risk for depression. Comparisons were made between those who forgot and those who remembered reports of screening symptoms made at the initial interview. In general, recall for symptoms of internalizing disorders (depression and anxiety disorder) was much worse than recall for symptoms of externalizing disorders (conduct disorder and substance use). Less than two-thirds of those initially meeting the lifetime depression screening criteria provided reports which met the lifetime screening criteria at followup. Significant correlates of screening criteria recall included the following variables (measured at the initial interview): history of treatment for any disorder, impairment on the GAS (a score less than 61), and the presence of hypersomnia and suicidal symptoms (thoughts or ideation). Logistic regression suggested that a prior report of suicidal symptoms (including thoughts, ideation, or behavior) was the most important correlate of screen recall.This research was supported in part by grants from the National Institute on Drug Abuse (grant R29DA07995), the National Institute of Mental Health (grant P50MH43878-03) and from the University of Illinois Campus Research Board.

The ability of middle-aged adults to recall their body size and events occurring up to 40 years earlier was assessed. Ninety-one
subjects recalled their relative height, weight, and fatness during childhood, early adolescence and late adolescence. Accuracy
of these memories was compared with the accuracy of current reports. The ability to accurately date benchmarks of their maturation
such as menarche and year of maximal growth in height was also examined. Accuracy of reports did not decline uniformly over
time. In general, reports of childhood physical characteristics were at least as accurate as reports of current characteristics;
that is, they did not differ significantly from current reports. Males were less accurate in their reports of relative height
and fatness during early adolescence and childhood.

To assess memory problems associated with attention deficit disorder with hyperactivity (ADDH) and reading disability (RD), nonverbal subspan, span, and supraspan measures was administered to 30 ADDH, 30 normal, and 24 RD boys, ages 7 to 12. Results from the supraspan verbal measures, which included word lists and related and unrelated paired associates, are reported. Across all verbal tasks, deficits became most apparent in ADDH boys on measures requiring organized, deliberate rehearsal strategies, sustained strategic effort, and careful consideration of response alternatives. This pattern suggests impaired self-regulatory or executive processes. RDs showed more generalized deficits across the verbal measures, suggesting problems with verbal processing. Recent studies supporting this interpretation are reviewed.This research was partially supported by Grant MA-6913 from the Medical Research Council of Canada. We are grateful for the help of Rhonda Amsel in the various stages of this project. 相似文献

Forty female undergraduates forming four groups, high or low trait anxiety with or without a specific fear (rats), participated in a psychophysiological assessment of their response to the phobic object, a neutral object (rabbit), and to a general anxiety-induction procedure (threat of shock). Subjects also completed a number of tasks requiring sustained attention. Blood samples were drawn to determine thyroid hormone (T3 and T4) levels. Trait anxiety was found to interact with specific fear in response to the feared object. The high-trait anxious/high-fear group was most physiologically responsive to the rat. Trait- anxious subjects were more responsive to the threat of shock and showed performance deficits on reaction time, vigilance, and backward digit span tasks. These subjects also had significantly higher T3 and T4 levels. The findings are discussed with regard to the role of general anxiety in the etiology and/or maintenance of specific fears and the role of thyroid hormones in accentuating physiological response to feared stimuli. 相似文献

Six adults with non-insulin dependent diabetes mellitus participated in a laboratory procedure to determine the effects of an acute Stressor, mental arithmetic, on blood glucose, cardiovascular, and subjective indices of stress. They then completed 12 days home monitoring of stressful events, subjective stress, and blood glucose. Diet and activity were controlled to evaluate the direct effects of stress on blood glucose in the natural environment. Laboratory results showed significant increases in blood glucose, cardiovascular (HR and SBP), and subjective stress ratings during the mental arithmetic task when compared to a resting condition. Home monitoring data were consistent with the laboratory findings; blood glucose range tended to be greater on high vs low stress days, especially when the difference between high and low stress was greatest. These findings suggest that the laboratory stress induction procedure was externally valid and that in the natural environment, stress has a hyperglycemic effect on blood glucose. 相似文献

The role of metacognition and executive processes in mediating use of study skills was examined in groups of attention deficit disorder with hyperactivity (ADD-H), normal, and non- ADD- H reading-disabled (RD) boys, matched on age and verbal IQ. On a story recall task, ADD- H boys did not differ from normals in their immediate gist recall of a story or in their recall following a study period. RD boys demonstrated inferior recall in both conditions. Study skills of the ADD- H boys were poorer than those of normal boys on all measures. They spent less time studying, expended less effort, and employed more superficial strategies. However, their poor strategies did not appear to reflect a lack of metacognitive awareness. Results are discussed in terms of the impact of motivational variables in modulating strategy use in ADD- H boys and the impact of verbal processing problems in reading disabilities. Implications for treatment and the relationship between ADD- H and RD are discussed.This research was supported by grant MA 6913 from the Medical Research Council of Canada. 相似文献

Graduating during COVID-19, the Class of 2020 had difficulty pursuing their future goals. This research examined the likelihood of academic and career goal change early in the pandemic, disparities in persistence by socioeconomic status (SES), and how psychological resources mitigated goal change during the early stages of the pandemic. This 4-year study surveyed students in the Class of 2020 eight times from their first week in college (Fall 2016) to their last semester before graduation (Spring 2020; N = 115; 20% below middle SES, 80% middle SES or above). Even in the first weeks of COVID-19, a quarter of students changed goals. Lower SES students were less likely to persist in their post-graduation plans. Nevertheless, students who entered college with a vivid image of their future were more likely to have secured a graduate school or job prospect prior to COVID-19, and, in turn, were less likely to change goals. 相似文献
