Procedures for assessing the invariance of factors found in data sets using different subjects and the same variables are often using the least squares criterion, which appears to be too restrictive for comparing factors.Tucker's coefficient of congruence, on the other hand, is more closely related to the human interpretation of factorial invariance than the least squares criterion. A method maximizing simultaneously the sum of coefficients of congruence between two matrices of factor loadings, using orthogonal rotation of one matrix is presented. As shown in examples, the sum of coefficients of congruence obtained using the presented rotation procedure is slightly higher than the sum of coefficients of congruence using Orthogonal Procrustes Rotation based on the least squares criterion.The author is obliged to Lewis R. Goldberg for critically reviewing the first draft of this paper. 相似文献

The efficacy of home practice assignments was evaluated as a component of standardized progressive relaxation training. Subjects reporting general anxiety and tension problems were assigned to either a home practice relaxation, no home practice relaxation or wait-list control condition. Treatment was conducted for 10 sessions over a 5-week period. In addition, subjects in both conditions engaged in in-vivo application of their relaxation skills during a final 2-week application period. Group comparisons showed that both progressive relaxation conditions significantly improved on daily self-monitored general anxiety and tension levels relative to the wait-list control condition. Group analyses of percent subject improvements supported the effectiveness of home practice assignments, especially during the application period. No systematic differences between groups, on physiological and self-report variables, were found during several laboratory relaxation evaluation sessions. This study supports the contribution of home practice assignments to progressive relaxation training. 相似文献

Members of over 100 families were administered the Wechsler Adult Intelligence Scale (WAIS) as well as various psychometric tests of personality. Individual cognitive and personality measures often were associated. Parent personality scale scores often were associated with offspring WAIS scores and vice versa. Stepwise multiple regressions demonstrated that knowledge of parental personality test scores substantially increased the predictability of offspring WAIS scores. 相似文献

The regression of adjustment—indexed by measures of anxiety and depression— on “masculinity” (instrumentality) and “femininity” (expressiveness)—as assessed by the BSRI, PRF ANDRO, and the Short BSRI—was studied in 122 college men. The findings revealed that: (a) anxiety and depression marked a single adjustment factor; (b) self-esteem mediated the relationships between instrumentality, expressiveness, and adjustment, such that when the variance due to it was removed, neither instrumentality nor expressiveness accounted for significant variance in Anxiety-Depression; (c) the Short BSRI index of expressiveness behaved differently from the other indices and more like that of the PAQ; (d) instrumentality and expressiveness interacted significantly, such that instrumentality was positively associated with adjustment for those with low or average expressiveness and expressiveness was positively associated with adjustment only for those with low or average instrumentality; and (e) men high in instrumentality and low in expressiveness reported slightly higher adjustment than “androgynous” men. 相似文献

The saltatory area, defined as that region of the skin within which two successive and spatinily separated signals will interact to produce apparent mislocalization of the prior signal, is measured by a campimetric technique applied to the palm, finger pad, and volar forearm. As contrasted with earlier measures on larger anatomical units, saltatory areas of the hand region are considerably compressed. Comparisons between cortical receptive fields and saltatory areas lead to speculation concerning the operation of the neural principle of “magnification” in the establishment of saltatory limits. The correspondence of configurational properties of both receptive fields and saltatory areas suggests a commonality of principles underlying both, but demands more information on the temporal dimensions of cortical interaction to confirm the parallelism. 相似文献

This paper describes the emergence and development of three object-related gestures: pointing, extending objects, and open-handed reaching, in four first-born infants from 9 to 18 months during natural interactions with their mothers. It examines the changing characteristics of the gestures and the acquisition of conventional words in accompaniment. Furthermore, it investigates the role that the capacity for dual-directional signaling, sending simultaneously two coordinated but divergently directed nonverbal signals of gesture and gaze, may play in this transition. Analysis revealed that dual-directional signaling appeared concurrently across gestures. In addition, dual-directional signaling was employed in a socially adjusted manner, more with pointing, especially spontaneous pointing when the mothers' attention could not be assumed. Verbal accompaniments appeared with gestures only when the children had mastered dual-directional signaling. Then words emerged approximately simultaneously with more than one kind of gesture. 相似文献

Thousands of children are injured or killed each year in school bus accidents. A significant number of these tragic incidents is precipitated by disruptive child behavior that distracts the drivers from their difficult task. Two experiments were conducted which addressed this problem. For both experiments an automated sound recording device (referred to as a Noise Guard) selectively responsive to frequencies above 500 Hz (i.e., unresponsive to bus drone) recorded both the duration and frequency of noise outbursts above a tolerable threshold. Additionally, an observer made in situ measurements of other disruptions including roughhousing and getting-out-of-seat. In the first experiment, following baseline measurements of these behaviors, middle-school students received feedback for noise outbursts. That is, when “Noise Guard'” was activated, it in turn operated one of several lights on a panel visible to all passengers. Each day students were allowed to listen to high-appeal taped music while riding the bus and to participate in a raffle for prizes, provided the number of outbursts on the preceding day remained below a specified criterion indicated on the light panel. This intervention resulted in drastic reductions of noise outbursts with a concomitant reduction in other disruptive behaviors. Comparable results were obtained in the second experiment which eliminated the raffle from the intervention. 相似文献

Twenty-five hospitalized nonfluent, fluent, and global aphasic patients who were several months past the onset of their illness were compared for presence and severity of depression based on four psychopathological measures. The nonfluent aphasic patients had both greater frequency and severity of depression than the other two groups. CT scans showed that the global aphasic patients had the largest lesion size (volumetric) and showed a strong correlation between lesion size and degree of depression. In contrast, patients with fluent aphasias showed an inverse correlation between severity of depression and lesion size; among the nonfluent aphasic patients there was no significant correlation. Depression appears to be common in this population of hospitalized aphasic patients with chronic illness and nonfluent patients are the most depressed group within this population. The increased frequency and severity of depression in the nonfluent patients did not appear to be related to their overall physical or cognitive impairment; two possible mechanisms are discussed. 相似文献

A total of 189 students in two studies rated jokes on funniness and several other scales after rating their own mood on the Nowlis-Green Mood Adjective Check List. Subjects in Experiment 1 gave a second and third set of mood ratings after their joke-funniness ratings. Three mood factors—surgency, elation, and vigor—reliably predicted joke appreciation in both studies. More tentative evidence linked humor appreciation to concentration, social affection, excitement, freedom, and (lack of) fatigue, but humor appeared independent of aggression, anxiety, tension, and inhibition. Relationships among joke-scale ratings were highly similar for subjects reporting relatively positive moods and those reporting more negative moods. Results were discussed with reference to several humor theories.The authors would like to thank Carol Pierce, Marguerite Ponder, and Ron Fox for their help with this research. 相似文献
