The purposes of this study are (1) to determine the incidence of significant clinical depression among alcoholics at treatment intake at a Veterans Medical Center, (2) to subdivide alcoholics who show significant clinical depression into enduring and transient depressive subgroups, and (3) to identify demographic and psychometric variables useful in discriminating between these two subgroups. Results indicate that of the 60% of VA inpatient alcoholics who showed evidence of significant clinical depression at intake, approximately equal numbers met criteria for inclusion in transient and enduring depressive subgroups. Patients with enduring and transient depression, as defined in this study, were differentiated on the basis of age, drinking pattern, and selected scales from two psychometric instruments which measure depression, confused and disorganized thinking, and an avoidant personality style. These findings may be useful in assisting clinicians in differentiating between alcoholic patients with transitory depression associated with alcohol consumption and/or withdrawal and alcoholic patients with more serious and enduring depression, which may require additional pharmacologic and/or psychotherapeutic intervention. 相似文献

Relationships between various personality styles measured by the basic and pathological personality scales of the Millon Clinical Multiaxial Inventory (MCMI) and mood or symptom states measured by the Profile of Mood State scales were examined. The MCMI personality scale-POMS symptom/mood scale relationships found in this study are compared with MCMI personality scale-MMPI and SCL-90 symptom/mood scale relationships reported in the MCMI manual. Consistent associations of moderate strength were found between: (a) the MCMI Compulsive-Conforming and Passive-Aggressive (Negativistic) scales (negative and positive associations, respectively) and various measures of depression, anxiety and hostility; (b) the MCMI Avoidant, Schizotypal and Borderline-Cycloid scales and various measures of depression and anxiety; (c) the MCMI Schizoid-Asocial scale and various measures of depression; and (d) the Histrionic-Gregarious scale and various measures of high energy-activity. These MCMI personality scale-symptom/mood scale relationships are generally consistent both with the underlying theory of personality and psychopathology upon which the MCMI is based and with the personality-symptom scale relationships found within the MCMI. 相似文献

Three experiments used a new paradigm to examine word-coding processes during reading. Subjects read text passages and occasionally responded to lexical-decision probes. Experiment 1 focused on semantic and surface codes. The activation of semantic codes appeared to increase over time, whereas surface codes did not. In addition, subjects who were instructed to remember the exact wording of the passages showed stronger activation of surface codes than did subjects who read for comprehension. Experiments 2 and 3 explored the role of phonological codes. Experiment 2 showed that phonological codes were activated by specific words in a passage. In contrast, Experiment 3 found no evidence that phonological codes were activated by the more general passage context. Taken together, the experiments suggest some of the roles semantic and phonological codes may play during reading. 相似文献

The purpose of this study was to investigate changes in postural sway and strategy elicited by lumbar extensor muscle fatigue. Specifically, changes in center of mass (COM), center of pressure (COP), and joint kinematics during quiet standing were determined, as well as selected cross correlations between these variables that are indicative of movement strategy. Twelve healthy male participants stood quietly both before and after exercises that fatigued the lumbar extensors. Whole-body movement and ground reaction force data were recorded and used to calculate mean body posture and variability of COM, COP, and joint kinematics during quiet standing. Three main findings emerged. First, participants adopted a slight forward lean post-fatigue as evidenced by an anterior shift of the COM and COP. Second, post-fatigue increases in joint angle variability were observed at multiple joints including joints distal to the fatigued musculature. Despite these increases, anterior-posterior (AP) ankle angle correlated well with AP COM position, suggesting the body still behaved similar to an inverted pendulum. Third, global measures of sway based on COM and COP were not necessarily indicative of changes in individual joint kinematics. Thus, in trying to advance our understanding of how localized fatigue affects movement patterns and the postural control system, it appears that joint kinematics and/or multivariate measures of postural sway are necessary. 相似文献

This paper describes the rationale for a randomized controlled trial, comparing cognitive behavior therapy in addition to treatment as usual with treatment as usual alone, for borderline personality disorder. Previous pioneering randomized controlled trials of psychotherapies have suffered from methodological weaknesses and have not always been reported clearly to allow adequate evaluation of either the individual study or comparisons across studies to be undertaken. We report on the recruitment and randomization, design, and conduct of an ongoing randomized controlled trial of one hundred and six patients with borderline personality disorder. Primary and secondary hypotheses and their planned analyses are stated. The baseline characteristics of 106 patients meeting diagnostic criteria for borderline personality disorder are described. 相似文献

Phonotactics and articulatory coordination interact in phonology: evidence from nonnative production
Davidson L 《Cognitive Science》2006,30(5):837-862
A core area of phonology is the study of phonotactics, or how sounds are linearly combined. Recent cross-linguistic analyses have shown that the phonology determines not only phonotactics but also the articulatory coordination or timing of adjacent sounds. In this article, I explore how the relation between coordination and phonotactics affects speakers producing nonnative sequences. Recent experimental results (Davidson 2005, 2006) have shown that English speakers often repair unattested word-initial sequences (e.g., /zg/, /vz/) by producing the consonants with a less overlapping coordination. A theoretical account of the experimental results employs Gafos's (2002) constraint-based grammar of coordination. In addition to Gafos's Alignment constraints establishing temporal relations between consonants, a family of Release constraints is proposed to encode phonotactic restrictions. The interaction of Alignment and Release constraints accounts for why speakers produce nonnative sequences by failing to adequately overlap the articulation of the consonants. The optimality theoretic analysis also incorporates floating constraints to explain why speakers are not equally accurate on all unattested clusters. 相似文献
