A stress inoculation training program involving relaxation, self-instructional, and coping skills training was delivered to 5 persons with traumatic brain injury in an attempt to reduce the frequency of their impulsive behaviors. A multiple-baseline across subjects design was utilized to evaluate the effectiveness of the 10-week intervention. Dependent measures included frequency of impulsive behaviors as recorded by staff members at the residential facility where all 5 participants resided, ratings of role-play-probes, effectiveness ratings by the participants' rehabilitation counselors, and interview information obtained from the participants and their counselors. The data showed a small, but consistent reduction in impulsive behaviors across the 5 participants. Additionally, results indicated changes in role-play ratings did not correspond to changes in in-vivo behavioral frequency recordings for 4 of the 5 subjects. These findings suggest that individuals with moderate to severe impairments may require more salient behavioral contingencies and consistent cuing procedures to control their impulsive behavior. 相似文献

This paper generalizes thep* model for dichotomous social network data (Wasserman & Pattison, 1996) to the polytomous case. The generalization is achieved by transforming valued social networks into three-way binary arrays. This data transformation requires a modification of the Hammersley-Clifford theorem that underpins thep* class of models. We demonstrate that, provided that certain (non-observed) data patterns are excluded from consideration, a suitable version of the theorem can be developed. We also show that the approach amounts to a model for multiple logits derived from a pseudo-likelihood function. Estimation within this model is analogous to the separate fitting of multinomial baseline logits, except that the Hammersley-Clifford theorem requires the equating of certain parameters across logits. The paper describes how to convert a valued network into a data array suitable for fitting the model and provides some illustrative empirical examples.This research was supported by grants from the Australian Research Council, the National Science Foundation (#SBR96-30754), and the National Institute of Health (#PHS-1RO1-39829-01). 相似文献

James Joyce's story, The Dead, is read in the tension between sameness, circularity, restraint, deadness as against possibilities for change, vitality, passion, and loving intimacy. The author plays two different readings of The Dead against each other to generate such tension in life and death struggles. Epiphanies are seen as beckoning us with the possibilities for radical transformation—an impossible illusion—but sufficient to tempt us to struggle against detachment, isolation, and restraint toward moments, of variable length, of intimate connectedness with ourselves and with others. 相似文献

Healthy systems in physiology and medicine are remarkable for their structural variability and dynamical complexity. The concept
of fractal growth and form offers novel approaches to understanding morphogenesis and function from the level of the gene
to the organism. For example, scale-invariance and long-range power-law correlations are features of non-coding DNA sequences
as well as of healthy heartbeat dynamics. For cardiac regulation, perturbation of the control mechanisms by disease or aging
may lead to a breakdown of these long-range correlations that normally extend over thousands of heartbeats. Quantification
of such long-range scaling alterations are providing new approaches to problems ranging from molecular evolution to monitoring
patients at high risk of sudden death.
We briefly review recent work from our laboratory concerning the application of fractals to two apparently unrelated problems:
DNA organization and beat-to-beat heart rate variability. We show how the measurement of long-range power-law correlations
may provide new understanding of nucleotide organization as well as of the complex fluctuations of the heartbeat under normal
and pathologic conditions. 相似文献

In four experiments, the effect of the semantic relationship between test and inducing stimuli on the magnitude of size contrast in an Ebbinghaus-type illusion was explored. In Experiments 1 and 2, the greatest illusion was found when test and inducing stimuli were identical in shape and differed only in size. Decreased size contrast was found when inducing stimuli were drawn from the same category as the test stimulus, but were not visually identical. Even less size contrast was found when inducing stimuli were from a near conceptual category, with the least effect when they were drawn from a completely different category. In Experiment 3, it was demonstrated that even if test and inducing stimuli are drawn with identical geometric elements, the size contrast illusion is greatly reduced if they represent apparently different conceptual categories (through the manipulation of orientation and perceptual set). In Experiment 4, any geometric or spatial confounds were ruled out. These results suggest that size contrast is strongly influenced by the conceptual similarity between test and inducing stimuli. 相似文献

Visual line fitting and direct estimation of the correlation coefficient were carried out by 50 subjects using computer-generated scattergrams as stimuli. In visual line fitting, slopes of visual lines were generally greater than the corresponding regression slopes, in agreement with the hypothesis that visual lines are placed so as to bisect the cloud of displayed points at the cloud's major axis rather than to approximate a regression line. Subjects tended to underestimate the correlation coefficient, scaling their judgments of linear structure somewhat more as if they were judging the coefficient of determination. With the actual degree of linear structure partialed out, there were no strong relationships between measures of visual line fitting and measures of estimation. While both of these tasks offer quickly-obtained correlates of linear structure in scattergrams, users should be aware of their biases. We suggest that visual lines do not approximate regression lines very well and estimates of correlation do not approximate the correlation coefficient very well, because the perceptual processes involved perform operations other than regression and correlation. In the present data, these operations appeared to be independent of each other. 相似文献

The Profile of Mood States was administered to 90 Australian women, 30 depressed, 30 anxious, and 30 nonpsychiatric controls. Both clinical groups scored higher than the McNair, Lorr, and Droppleman (1971) normative samples on the negative mood states and scored lower on Vigor. The means for these groups are presented and compared with the 1971 normative data of McNair, Lorr, and Droppleman. 相似文献

The Arousability Predisposition Scale (APS) was used to assess individual differences in arousal that occur when a task is performed under conditions of environmental distraction. The APS is a brief (12-item) scale, that purportedly measures arousability as a trait or predisposition. To manipulate arousal experimentally, subjects performed a speeded search task under conditions of visual and auditory distraction. Pre- and postdistraction task measures of arousal were taken using Thayer's Activation-Deactivation Adjective Check List. The distraction task caused a general increase in arousal as compared to a control group who did not perform the task. Although there were no differences in pretest measures, subjects judged highly arousable on the APS showed a greater change in task-related arousal than subjects judged low on arousability, validating the usefulness of the APS as a measure of arousability under conditions of environmental stress. 相似文献

Prochaska and colleagues’(e.g., Prochaska, DiClemente, & Norcross, 1992) stages‐of‐change theory was employed in the current study to reconceptualize the assessment of motivation to learn. We used the stages‐of‐change framework to develop and test a multidimensional measure of learning motivation using 3 independent samples. The pattern of relationships among the learning stages and learning criteria provided strong support for the appropriateness of using a stage‐based perspective to frame learning motivation. In addition, hierarchical regression analysis showed that the Stages of Learning Motivation Inventory (SOLMI) explained variance in the criteria (e.g., exam average, class satisfaction) beyond controls and a commonly used measure of learning motivation. Implications for practice and future research are discussed. 相似文献
