Eighty-two subtests chosen from a series of preceding researches as the best marker variables for 12 previously checked and interpreted personality factors (U.I. 16, 17, 19, 20, 21, 23–26, 28, 32, and 33) were administered to 2,522 boys of high school age. The ensuing factor analysis, aimed to check and precision the factor patterns, to lead to the definitive HSOA battery, and to yield scores for further age and genetic analyses, observed the following procedural requirements: (1) Scree test for number of factors, (2) iterated communalities, (3) blind automated rotation, carried further by rotoplot to a maximum simple structure, (4) a test of simple structure significance, and (5) matching of patterns for invariance against other studies. As before in this domain, 19–20 factors were found, and the 10 for which definite markers had been made available matched very well with former patterns. Although a small minority of tests failed to load as hypothesized, this results in some weakness of factor estimate only on U.I. 32, Exvia-Invia. For on all 10 factors for the planned HSOA battery, with this possible exception, the validities of weighted battery scores reached acceptable levels.  相似文献

Thirty 4–6.5 mo-old-infants from monolingual Spanish speaking homes were tested for discrimination of bilabial stop consonants differing in VOT. Discrimination was determined by the habituation and dishabituation of the orienting reflex as indexed by cardiac deceleration. Subjects were placed in one of three groups of ten subjects each. The three groups were used to determine whether bilabial stops with VOT values of ?60 and ?20 msec, ?20 and +20 msec or +20 and +60 msec could be discriminated. Subjects were presented eight trial blocks of ten repetitions of a CV syllable; these eight trial blocks were followed by two trial blocks of ten repetitions of a different CV syllable. The only difference between the CV syllables presented during the first eight and the last two trial blocks was the VOT value of the bilabial stop consonants. Subjects in the ?20 and +20 msec group showed no signs of being able to discriminate these stimuli while the subjects in the ?60 and ?20 msec group and the +20 and +60 msec group did. These results correspond to those reported for infants from English speaking families but do not correspond to those reported for Spanish speaking adults. Thus, the failure to find evidence of discrimination in the ?20 and +20 msec group suggests that experience has little effect in determining bilabial stop phonetic categories in 4–6.5 mo-old infants.  相似文献

A modified Solomon design was employed to study the effects of a school psychology simulation package on the enacted and written response of a group of school psychology preservice students. Fifty-two school psychology students from five training programs enrolled in the last quarter of school psychology training prior to internship were divided into two groups. The experimental group (N=20) received the simulation experience, whereas the control group (N=32) did not. Results generally indicated the superiority of the experimental group and suggested that simulation as an integral part of a school psychology training program is an effective method of instruction. Pretesting in combination with the simulation training improved posttest performance more than simulation training alone.  相似文献

The results of two experiments demonstrated that retention deficits occurred in a within-subjects design only when the intermediate interval test was either the first or second test of the retention of prior aversive conditioning experience; when two relearning tests preceded a 1-hr test, no performance deficits were observed. It was suggested that internal cues may serve as memory attributes of avoidance behavior during early stages of avoidance learning, while other stimuli may facilitate the retrieval of the memory of prior avoidance training with repeated testing.  相似文献

Depressed and nondepressed college students received experience with solvable, unsolvable, or no discrimination problems. When later tested on a series of patterned anagrams, depressed groups performed worse than nondepressed groups, and unsolvable groups performed worse than solvable and control groups. As predicted by the learned helplessness model of depression, nondepressed subjects given unsolvable problems showed anagram deficits parallel to those found in naturally occurring depression. When depressed subjects attributed their failure to the difficulty of the problems rather than to their own incompetence, performance improved strikingly. So, failure in itself is apparently not sufficient to produce helplessness deficits in man, but failure that leads to a decreased belief in personal competence is sufficient.  相似文献

Research by Mintz and Kelley, Condry, Dahke, and Hill left unresolved the question of what level of personal threat leads to group incoordination of "panic behavior." The present study set out to resolve this issue and to explore the additional relationship between leadership and behavior in the panic situation. The dependent variables were Likert-type questionnaire items designed to investigate the level of responsibility attributed to a leader by members of a group as a function of four variables: (a) two levels of stress (threat of shock or of small monetary loss); (b) two levels of leadership authority (elected or appointed); (c) two conditions of leadership ("me-last" or "me-first"); and (d) group success or failure. The specific questions were adapted from earlier pilot work by Sulzer and Sisti. One hundred and forty-four males were run in this 2 X 2 X 2 X 2 factorial design with a nonfactorial control group. The task setting, which required subjects to retrieve their wooden cones through the same hole, was designed to be analogous to the kind of situation that would occur in a theater fire where only one narrow exit existed. The results support the contention of Kelley that group incoordination (panic) increases under personal threat. Additional results were: (a) Leaders facilitated achieving the goal of safe exit; (b) elected leaders were given more responsibility and were seen as more competent than appointed leaders, but only when the stress is comparatively low, as otherwise the difference in evaluation narrows and reverses; and (c) success or failure seems to have had little effect on the leader's evaluation by the group.  相似文献

The purpose of the present study was to examine the role of interest-present job congruency as a moderator of the relationship between job tenure and job satisfaction and mental health. In a sample of 54 middle managers, significant moderator effects were found for the mental health indices of self-esteem, life-satisfaction, and overall mental health and for satisfaction with supervision. As expected, these indices correlated positively with job tenure for high congruency individuals. For low congruency individuals, the relationships were expected to be negative. However, the obtained correlations did not differ significantly from zero.  相似文献

This study evaluated the effectiveness of a 16-week intensive cognitive training program in stimulant-treated, academically deficient ADDH boys. Cognitive training focused exclusively on academic skills and tasks, and included attack strategy training as well as self-monitoring and self-reinforcement of problem-solving behaviors and response accuracy. Control groups included remedial tutoring plus medication, and medication alone. Despite the scope of the program, the results provided no support for the notion that academically based cognitive training ameliorates the performance and achievement of academically deficient ADDH youngsters. Further, this intervention did not enhance self-esteem or attributional perceptions of academic functioning. There was poor agreement between teacher ratings of academic competence and test score changes. The lack of concordance between measures, and the scarcity of academically deficient ADDH children are discussed.Preparation of this article was supported in part by National Institute of Mental Health Grant MH30822.  相似文献
