We introduce two new scales for assessing substance abuse problems with the Minnesota Multiphasic Personality Inventory-2 (MMPI-2): the Addiction Potential Scale (APS), a 39-item empirically derived scale, developed by contrasting the responses of a large residential substance abuse sample with responses from both normative and psychiatric control groups; and the Addiction Acknowledgement Scale (AAS), a 13-item face-valid scale, constructed rationally and with attention to internal consistency. Both new scales are shown to discriminate well between groups and substantially better than other selected substance abuse scales. Covariation between the scales and joint effectiveness are examined. Finally, limitations for their practical utility are expressed, and considerations for future research are identified.  相似文献

An experiment was conducted to address the relation between theories of selective attention and theories of divided attention by examining the pattern of task interference between visual scanning as a sequential and selective attention process and other concurrent spatial or verbal processing tasks. A distinction is proposed between visual scanning with or without spatial uncertainty regarding their possible differential effects on interference with other concurrent processes. The experiment required the subjects to perform a primary tracking task, which was concurrently performed with a secondary spatial or verbal decision task. The relevant information that was needed to perform the decision tasks was displayed with or without spatial uncertainty. The results provide evidence that visual scanning as a spatial exploratory activity produces greater task interference with concurrent spatial tasks than with verbal tasks. Furthermore, spatial uncertainty in scanning is identified to be the crucial factor in producing this differential effect.  相似文献

The relationship between personality characteristics and color preference was investigated. Of 49 women and 17 men, 30 individuals scoring above the mean on an anxiety scale preferred significantly less saturated colors than 36 individuals scoring below the mean.  相似文献

Ss wielded an occluded L-shaped rod and attempted to perceive the direction in which the rod was pointing with respect to the hand. The pattern of the rod's different resistances to rotation in different directions, quantified by the inertia tensor, changes systematically with the rod's orientation. Perception of orientation by wielding is possible if the tissue deformation consequences of the rod's inertia tensor are detectable. It was shown that perceived orientation was a linear function of actual orientation for both free and restricted wielding and for rods of different-size branches. The eigenvectors of the inertia tensor were implicated as the basis for this haptic perceptual capability. Results were discussed in reference to information-perception specificity and its implications for effortful or dynamic touch.  相似文献

The hypothesis that psychosocial contextual factors contribute to developmental changes in memory was examined using 326 male World War II veterans. Availability of young adult intelligence scores made it possible to separate the contributions of contextual variables and age to maintenance of general intelligence from their direct contributions to performance on 4 memory tasks. Being younger, healthier, more educated, more introverted, more intellectually active, and more satisfied with social support predicted less intellectual decline and, indirectly, better memory performance. Age, personality, locus of control, and extent of social support directly contributed to performance on 1 or more memory tasks. Age contributions were consistent with Craik's (1986) proposed continuum of task demands for self-initiated effort. Possible elaborations of Craik's hypothesis to accommodate contextual variables are suggested.  相似文献

Human fetal cardiac responses (36-39 weeks gestational age) to brief, repeated vocal stimuli (male or female voice uttering the same sentence), given at 90-95 dB SPL ex utero (around 20-30 dB less in utero) during a state of low fetal heart rate (FHR) variability, were examined using highly conservative statistical criteria taking into account each subject's prestimulus FHR variability. Subjects exposed to either of the two stimuli displayed significantly more decelerative heart rate (HR) changes compared to control subjects receiving no stimulation. The decelerative changes started during the first seconds following the onset of stimulation and reached their amplitude peak within 10 or 20 sec, depending on the subject. The direction--HR acceleration or deceleration--and the amplitude of the response depended on prestimulus HR variability only, not on prestimulus level. No major difference was found between the effects of the two voices. The data are compared to previous studies demonstrating fetal decelerative changes to acoustic stimuli of less than 105 dB SPL. The choice of an objective criterion to define an HR response and the possible orienting response nature of the decelerative change are discussed.  相似文献

Based on findings from the domain of organizational frustration, the conceptual similarity between stress and frustration, and the functional similarity between frustrated events and work stressors, the relationships of behaviours (aggression, withdrawal, theft and substance use) with work stressors and affective reactions were investigated. Relations between reported stressors and behaviours were strongest for the more directly aggressive actions (sabotage, interpersonal aggression, and hostility and complaints), and for intention to quit. Relations with theft and absence were modest. None of the stressors correlated with reported substance use at work. Among the relations between affective reactions and the reported behaviours, anger and job satisfaction correlated with all behaviours except substance use at work. Hierarchical regression results further showed that the observed associations between stressors and behaviours were not attributed to affective variables for most cases.  相似文献

This research examined relationships between parental interpersonal perceptual style (IPS)—the extent to which they are biased in their perceptions of children's behaviors—and (a) the adjustment of their own children and (b) parent-child interactions. In two studies, groups of parents first viewed a videotape of a male or female target child interacting with an adult in a playroom and then completed a behavior checklist about the target child that measured their IPS. In Study 1, parents' (especially fathers') IPS was found to be related to interaction between them and their 5-to7-year-old child; for example, the less negatively biased the father was, the more likely the child was to openly display antagonistic behavior toward his or her parents. In Study 2, fathers' (but not mothers') IPS was found to be related to the teacher- and peer-assessed level of psychosocial adjustment of their own third-grade child; fathers of problem children tended to be more negatively biased in their perceptions than were fathers of either adequate or highly adjusted children. Findings are discussed in terms of their implications for understanding the role that person perception processes play in family functioning and child development.This article is an adaptation of a paper presented as part of a symposium held during the 1977 meeting of the American Psychological Association. This research was supported by National Institute of Mental Health Grant No. 24250, Adult Perceptions and Child Behavior Dysfunctions.We wish to thank Linda Oiacomo and Phyllis Watts for their help. We also wish to thank the numerous students who provided invaluable assistance by collecting, coding, and scoring the data. The cooperation of the administration and staff of the Lansing, Michigan, School District, especially Eva Evans and Richard Benjamin, and the administration and staff of the East Lansing, Michigan, School District, especially Robert Docking and Warren Starr, is also very gratefully acknowledged.  相似文献
