The hypothesis that negative daily events mediate the relationship between major negative events and psychological symptomatology was tested using a three-wave, three-variable panel design. Measures of major and daily life events and psychological symptomatology were administered to 58 older adolescents at three time points during the transition from high school to college. The results indicated that the pathways from major life events to daily events and from daily events to psychological symptomatology were significant at each of the time points, but that the direct pathways from major events to psychological symptomatology were not significant at any time point. Thus, the hypothesis was fully supported. The findings are discussed in light of their implications for an integrative theory of the process by which major and daily events have an effect on psychological symptomatology. 相似文献

Empirically based assessment of the behavioral/emotional problems of 2- and 3- year-old children 总被引:11,自引:0,他引:11

The aim was to determine whether ratings of 2- and 3-year-olds could yield more differentiation among their behavioral/emotional problems than the internalizing-externalizing dichotomy found in previous studies. The 99-item Child Behavior Checklist for Ages 2–3 (CBCL/2–3) was designed to extend previously developed empirically based assessment procedures to 2-and 3-year-olds. Factor analyses of the CBCL/2–3 completed by parents of 398 2- and 3-year-olds yielded six syndromes having at least eight items loading 30 and designated as Social Withdrawal, Depressed, Sleep Problems, Somatic Problems, Aggressive, and Destructive. Second-order analyses showed that the first two were related to a broad-band internalizing grouping, whereas the last two were related to a broad-band externalizing grouping. Scales for the six syndromes, two broad-band groupings, and total problem score were constructed from scores obtained by 273 children in a general population sample. Mean test-retest reliability r was 87, 1-year stability r was 69, 1-year predictive r with CBCL/4–16 scales at age 4 was 63, 2-year predictive r was 55, and 3-year predictive r was 49. Children referred for mental health services scored significantly higher than nonreferred children on all scales. A lack of significant r's with the Minnesota Child Development Inventory, Bayley, and McCarthy indicate that the CBCL/2–3 taps behavioral/emotional problems independently of the developmental variance tapped by these measures.This research was supported by March of Dimes Birth Defects Foundation Grants 12–88 and 12–186, a Faculty Scholars Award from the W.T.

Study 1 examined the hypothesis that ego-involvement leads to positive self-schema activation. Ego-involvement was induced by having experimental subjects anticipate a difficult test of intelligence. Noninvolved control subjects did not anticipate the test. All subjects completed a depth-of-processing task, following which incidental recall was assessed. Ego-involved relative to noninvolved subjects tended to recall a greater number of positive and fewer negative words at both the self-referent and semantic processing levels. Study 2 was conducted to address further the self-schema hypothesis and to address the hypothesis suggested by the results of Study 1 that ego-involvement leads to a positivity bias in information processing. The design of Study 2 was similar to that of Study 1. Results revealed that the self-favorability of negative words recalled at the self-referent level was greater for ego-involved than for noninvolved subjects, suggesting positive self-schema activation. In addition, ego-involved subjects recalled a greater number of positive words at the semantic level, suggesting a positivity bias in information processing.Study 2 was conducted by Andrew Howell in partial fulfillment of the requirements of a Master of Arts degree at Concordia University, under the supervision of Michael Conway.

To advance the empirical identification of child/adolescent syndromes, principal components analyses were performed on four sets of parents' ratings of 8,194 6- to 16-year-olds referred to American and Dutch mental health services. The following syndromes replicated well for both sexes at ages 6-16: Aggressive, Anxious/Depressed, Attention Problems, Delinquent, Somatic Complaints, and Withdrawn. For both age ranges, a syndrome designated as Socially Inept replicated well among boys, and one designated as Mean replicated well among girls. Evidence was also found for a Schizoid syndrome in all sex/age groups and a Sex Problems syndrome among girls at ages 6-11. Syndrome scores discriminated well between nationwide normative and clinical samples. The replicated syndromes contribute to the empirical basis for a taxonomy of the kinds of disorders commonly seen between the ages of 6 and 16. 相似文献

Letter-like targets (a circle and a square) were presented in one of two fixed and cued visual field locations and were shown alone, flanked by a noise stimulus on the peripheral side (side of target farthest from fixation), on the central side, or on both sides simultaneously. The adjacent target and noise stimulus borders had similar featural properties (both curved or both straight lines) or dissimilar properties (one being a curved line and one a straight line). Each of 10 subjects made a go, no-go response only when his or her designated target appeared in a display. The results showed: (1) single targets were discriminated more accurately and more rapidly than were targets shown simultaneously with noise stimuli, (2) targets having dissimilar border relationships with noise items were discriminated more accurately than were targets having similar border relationships, (3) targets in central-noise displays were discriminated more accurately and rapidly than were targets in peripheral-noise displays, and (4) there was no interaction between border relationships and noise position. The principal result relating to target-noise border featural relationship was consistent with predictions derived from models which place the locus of noise effects at the stage of stimulus feature extraction. Aspects of the results were, however, seen to be consistent with both feature extraction and response competition conceptualizations. 相似文献

Three experiments that were designed to determine how pitch information is represented in auditory memory are reported. A same-different reaction time was used in all three experiments. Previous experiments have interpreted the finding of faster “same” responses to acoustically identical pairs than to pairs that are phonemically identical but acoustically distinct as indicating that there is a memory that preserves auditory information. It has been assumed that this can be used to match “same” pairs only if the formant frequencies of the members of the pair are the same. In the first experiment, the size of this matching advantage for pairs with identical formant frequencies was not altered when the members of the pair were on different pitches. This indicates that pitch is represented separately from the formants at the auditory level. The second and third experiments used a bigger pitch difference when the pairs were on a different pitch, which, for one of the stimulus sets, resulted in a change in vowel quality but not in the identity of the consonant. In the other stimulus set, both phonemes of the syllable remained the same when presented on different pitches. The matching advantage was reduced when the stimuli were on different pitches for both stimulus sets. This indicates that a difference in pitch can prevent matching at the auditory level under some circumstances. An additional finding, a reduced residual matching advantage when the syllable changes, indicates that at least a syllable-length representation is held in auditory memory. The results are discussed with respect to how the representation in auditory memory might be used in the perception of speech produced by different speakers. 相似文献

Ecofeminism refers to feminist theory and activism informed by ecology. Ecofeminism is concerned with connections between the domination of women and the domination of nature. Although ecofeminism is a diverse movement, ecofeminist theorists share the presuppositions that social transformation is necessary for ecological survival, that intellectual transformation of dominant modes of thought must accompany social transformation, that nature teaches nondualistic and nonhierarchial systems of relation that are models for social transformation of values, and that human and cultural diversity are values in social transformation. Ecofeminist theology, ethics, and religious perspectives are particularly concerned with the integration of science and religion. Examples of religious or spiritual ecofeminisms are North American Christian ecofeminism, North American womanist Christian theology, neopagan Wiccan ecofeminism, Native American ecofeminism, and Third World ecofeminism. 相似文献
