Diurnal Patterns of Unpleasant Mood: Associations with Neuroticism, Depression, and Anxiety 总被引:1,自引:0,他引:1
The literature on symptoms of depression has included diurnal changes in mood. The morning-worse pattern is commonly mentioned. This pattern is often associated with endogenous or vegetative symptoms (e.g., weight and appetite loss, loss of pleasure, psychomotor retardation). However, depression researchers have also identified an evening-worse pattern of mood. This pattern is sometimes thought to be associated with milder depressive symptoms, and may characterize chronic dysthymia rather than clinical depression. The present study examines a nonclinical sample to test the hypothesis that an evening-worse diurnal pattern of mood would be associated with trait neuroticism, anxiety, and subclinical depressive symptoms. An experience sampling methodology was employed to assess mood three times a day for 60 consecutive days. This allowed us to calculate a reliable aggregate score for diurnal mood patterns. The evening-worse pattern was associated with many neurotic features, with scores on depression and anxiety measures, and with a cognitive style indicative of hopelessness. Discussion focuses on how an evening-worse diurnal pattern of mood may be indicative of mild subclinical depression, chronic dysthymia, or personality traits associated with negative affectivity. 相似文献

Subjects in Phase 1 of this experiment were (a) instructed to try to either increase or decrease their heart rate, (b) with or without the use of biofeedback, and (c) with or without the promise of money for successful performance, whereas no-treatment subjects were given no instructions, no biofeedback, and no promise of reward. Results indicated that (a) when simply instructed to do so, subjects could increase but not decrease their heart rates relative to no treatment controls, (b) the promise of money for good performance aided subjects in increasing but not decreasing heart rate, and (c) biofeedback did not aid subjects in either increasing or decreasing heart rate. Various cognitive strategies employed by subjects in controlling their heart rates are discussed.In Phase 2, subjects in a stress condition were told that they would receive a series of painful electric shocks, whereas subjects in a no stress condition were not told about shocks. All subjects were instructed to try to decrease their heart rates during the “shock” period. Heart rate and self report data revealed that (a) the manipulation was successful in increasing stress, and (b) previous training in decreasing heart rate, with or without biofeedback, did not aid subjects in decreasing their heart rates in the face of the stress. 相似文献

Seventy-one normotensive subjects participated in four training sessions in which they were either (a) instructed to increase their blood pressure, (b) instructed to decrease their blood pressure, or (c) not instructed to change their blood pressure. The subjects either (a) were provided with biofeedback concerning systolic blood pressure or (b) were not provided with biofeedback concerning systolic blood pressure. After the last training session, subjects participated in a transfer session in which they were again instructed concerning changes in pressure but were not provided with biofeedback. Analyses conducted on data from the training and transfer sessions indicated that subjects who were instructed to increase pressure and given biofeedback to aid them showed higher pressure than subjects in other conditions and that there were no differences among those other conditions; that is, biofeedback was effective for teaching subjects to increase pressure but was not effective for teaching subjects to decrease pressure. Additional training sessions did not add to the effect achieved in the first training session. During training sessions, subjects who were instructed to increase pressure showed higher heart rates than subjects in other conditions. The results raise questions concerning the interpretation of earlier experiments that did not include no-treatment, instructions-only, and attention control conditions. 相似文献

Various types of acoustic cues have been shown to signal voicing contrasts in initial prestressed stop consonants. Two of the most important of these cues are the time interval between the release burst and the onset of voicing (voice onset time) and the duration of voiced transitions. In the present experiment, a selective adaptation procedure was used to investigate possible feature extraction mechanisms which underlie the perception of voicing. Subjects first identified either of two series of test stimuli, [ba-pha) or [ga-kha]. Next they listened to repeated presentations of an adapting stimulus and then again identified the original test series. Adapting stimuli having the same value of voice onset time but different voiced transition durations produced differential (and sometimes opposite) effects on the identification of the test stimuli. In every case, the adapting stimulus with the greater duration of voiced transitions led to larger reduction in voiced responses or to a smaller increase in voiceless responses. These results are incompatible with models of voicing perception based strictly on detectors for voice onset time. The results also suggest that the adaptation effect occurs at a point in the system prior to the actual phonetic decision. 相似文献

To test for a relation between individual differences in personality and neural-processing efficiency, we used functional
magnetic resonance imaging (fMRI) to assess brain activity within regions associated with cognitive control during a demanding
working memory task. Fifty-three participants completed both the self-report behavioral inhibition sensitivity (BIS) and behavioral
approach sensitivity (BAS) personality scales and a standard measure of fluid intelligence (Raven’s Advanced Progressive Matrices).
They were then scanned as they performed a three-back working memory task. A mixed blocked/ event-related fMRI design enabled
us to identify both sustained and transient neural activity. Higher BAS was negatively related to event-related activity in
the dorsal anterior cingulate, the lateral prefrontal cortex, and parietal areas in regions of interest identified in previous
work. These relationships were not explained by differences in either behavioral performance or fluid intelligence, consistent
with greater neural efficiency. The results reveal the high specificity of the relationships among personality, cognition,
and brain activity. The data confirm that affective dimensions of personality are independent of intelligence, yet also suggest
that they might be interrelated in subtle ways, because they modulate activity in overlapping brain regions that appear to
be critical for task performance. 相似文献

Responses to Depression in Children: Reconceptualizing the Relation Among Response Styles 总被引:2,自引:1,他引:1
We propose that researchers should utilize ratio scores when examining the response styles theory rather than examine each of the response styles separately. Higher ratio scores indicate a higher probability of engaging in ruminative, as opposed to distracting and problem solving, behaviors. In Phase One, we examined the factor structure and reliability of the Children's Response Styles Questionnaire (CRSQ) in a sample of 287 third through sixth grade schoolchildren. A two factor solution was obtained: (1) Rumination and (2) Distraction and Problem Solving. Both factors exhibited strong psychometric properties. In Phase Two, 140 children completed the CRSQ and the Children's Depression Inventory (CDI). Six weeks later, children completed the CDI. Confirmatory factor analysis indicated that the two-factor solution fit the data well. In line with hypotheses, CRSQ ratio scores were more strongly associated with CDI residual change scores than were either CRSQ rumination or distraction and problem solving scores. 相似文献

The therapeutic relationship is the source of major concepts in psychoanalytic clinical theory. Such concepts as resistance, transference, countertransference, and the alliance are fundamental, even though there may be shifts in meaning between theoretical schools and clinical contexts. In the clinical psychoanalytic literature, disagreement exists over the nature of the alliance and its essential components. Empirical studies using reliable patient, therapist, and observer scales to assess the alliance demonstrate a correlation with psychotherapeutic gains. In the study reported here, thirteen patients were followed for 6 to 33 months of psychodynamic psychotherapy, during which time their views of the therapeutic relationship were assessed, and several experiential measures taken, all on a weekly basis. Statistical analyses reveal that the therapeutic relationship, as reflected in the patients' weekly responses to the St. Louis Therapeutic Relationship Rating Scale, has four distinct components: therapeutic alliance, resistance, transference love, and negative transference. On a week-by-week basis, the therapeutic alliance was the strongest predictor of improvement in patient-reported general adjustment, as reflected in such areas as self-esteem, positive affect, social relations, work productivity, satisfaction, and optimism. Time plots of the variables show the typical time course for the components of the therapeutic relationship, as well as for improvement on the experiential variables. Results indicate that the therapeutic alliance, transference, and resistance are central components of the psychotherapeutic relationship, which in turn predict the ongoing life experience of the patient. 相似文献

Working memory (WM) was studied in 82 healthy volunteers, 43 schizophrenia patients, and 81 bipolar patients. Schizophrenia patients were impaired on verbal and figural WM tasks that possessed similar test discriminating power. Bipolar patients performed similarly to healthy volunteers. A mathematical model of WM performance revealed a primary role for reduced WM span in accounting for the impaired verbal WM of schizophrenia patients and a primary role for diminished attention in accounting for impaired figural WM. Although WM impairment in schizophrenia is due neither to the general effects of severe mental illness nor to the specific type of material studied, the microarchitecture of abnormal WM in schizophrenia may depend on the stimulus material presented. 相似文献
