Illness course separates patients with atypical depression into tricyclic responders and nonresponders as does perceptual asymmetry. The authors therefore investigated whether the course-of-illness parameters would define groups within atypical depression differing in brain laterality. Patients with atypical depression were assessed for illness course and brain laterality. Two patient groups were defined, 1 with onset prior to age 20 plus a very chronic course, and a 2nd group having later onset or less chronic illness. Patients reporting early onset of very chronic dysphoria showed significantly less right-ear (left-hemisphere) accuracy and also differed in characteristic perceptual asymmetry when compared to patients with later onset or less chronicity. Course of illness may usefully define more homogeneous depressive subgroups within atypical depression. 相似文献

Although many social psychological researchers have tried to identify the antecedents of unethical or immoral behavior, investigators have little considered the content of ethical beliefs that associate with important personality variables such as authoritarianism (B. Altemeyer, 1981, 1996) and social dominance orientation (SDO; J. Sidanius, 1993). Previous studies suggest that authoritarianism is associated with the rejection of relativistic standards for moral actions and--to a lesser extent--the idealistic belief that moral actions should not harm others (J. W. McHoskey, 1996). In the present study, 160 New Zealand University students completed measures of SDO (J. Sidanius), Right Wing Authoritarianism (RWA, B. Altemeyer, 1981), and two subscales of ethical ideology: Relativism and Idealism (D. R. Forsyth, 1980). As expected, SDO showed a negative relationship with Idealism, a belief that actions should not harm others. But, contrary to expectations, SDO showed no consistent association with relativism, a belief that the moralities of actions are not comparable. On the basis of those findings, people with high SDO might be described as "ruthless" in their pursuit of desirable goals and are indifferent about whether the morality of different actions can be compared or even matter. 相似文献

The present research tested relations between extraversion and emergent leadership among men in situations that differed in potential reward availability. Four-person groups of men engaged in a Leaderless Group Discussion (LGD) task and were randomly assigned to be evaluated by an attractive female observer, an attractive male observer, or not be evaluated. Evolutionary theories suggest that impressing a female evaluator in an intrasexually competitive situation should hold greater reward potential for men than impressing either a male evaluator or no evaluator. Accordingly, more extraverted men (who are more sensitive to reward cues) should display more group leadership when being evaluated by a woman than either a man or no one. Self-and peer ratings confirmed that more extraverted men were significantly more likely to emerge as leaders, but only in the female-evaluator condition. The results are discussed in terms of the interplay between personality, situational factors, and evolutionary principles. 相似文献

The chronic mild stress (CMS) procedure was developed in rodents to target anhedonia, the core symptom of depressive melancholia. Stress exposure has been shown to induce a variety of physiological, biochemical and behavioral alterations associated with depression, although its anhedonic consequences as indexed by either sucrose intake and preference or thresholds for brain stimulation reward are less reliably observed. In the present study, we assessed the effects of six weeks of CMS on the latter measure in two strains of male and female rats subsequently challenged with an acute psychophysical stressor, forced swimming; their behavior in the swimming cylinder was evaluated on two consecutive days. While brain stimulation reward thresholds and response rates were unchanged by CMS exposure, significant differences in forced swim behaviors were observed between male control and CMS groups. In particular, male Long Evans rats with a history of CMS showed the largest decrease in the duration of active behaviors on the second test day, a pattern less evident in the Sprague-Dawley strain of rats, or in any of the female groups. The results suggest that the effects of depressogenic manipulations are strain and gender dependent, with male Long Evans rats most susceptible, as demonstrated by the selective reduction of struggling behaviors. Inclusion of multiple measures, including the forced swim test, would provide a better understanding of the psychopathological profile engendered by chronic exposure to mild stressors and its genetic specificity. 相似文献

The current article presents a basic functional-analytic interpretation of metaphor. This work involves an extension of Skinner's (1957) interpretation of metaphor using relational frame theory (RFT). A basic RFT interpretation of a particular metaphor is outlined, according to which the metaphor acquires its psychological effects when formal stimulus dimensions are contacted via the derivation of arbitrary stimulus relations. This interpretation sees the metaphor as involving four elements: (a) establishing two separate equivalence relations, (b) deriving an equivalence relation between these relations, (c) discriminating a formal relation via this equivalence-equivalence relation, and (d) a transformation of functions on the basis of the formal relation discriminated in the third element. In the second half of the paper, a number of important issues with regard to the RFT interpretation of metaphor are addressed. 相似文献

Corporal Punishment by American Parents: National Data on Prevalence, Chronicity, Severity, and Duration, in Relation to Child and Family Characteristics 总被引:19,自引:0,他引:19
We present data on corporal punishment (CP) by a nationally representative sample of 991 American parents interviewed in 1995. Six types of CP were examined: slaps on the hand or leg, spanking on the buttocks, pinching, shaking, hitting on the buttocks with a belt or paddle, and slapping in the face. The overall prevalence rate (the percentage of parents using any of these types of CP during the previous year) was 35% for infants and reached a peak of 94% at ages 3 and 4. Despite rapid decline after age 5, just over half of American parents hit children at age 12, a third at age 14, and 13% at age 17. Analysis of chronicity found that parents who hit teenage children did so an average of about six times during the year. Severity, as measured by hitting the child with a belt or paddle, was greatest for children age 5–12 (28% of such children). CP was more prevalent among African American and low socioeconomic status parents, in the South, for boys, and by mothers. The pervasiveness of CP reported in this article, and the harmful side effects of CP shown by recent longitudinal research, indicates a need for psychology and sociology textbooks to reverse the current tendency to almost ignore CP and instead treat it as a major aspect of the socialization experience of American children; and for developmental psychologists to be cognizant of the likelihood that parents are using CP far more often than even advocates of CP recommend, and to inform parents about the risks involved. 相似文献

There are few clinical or biologic predictors of response to treatments for depression. This article reviews growing evidence that electrophysiologic and neurocognitive measures of brain function may be of value as predictors of therapeutic response to antidepressants. Initial studies using dichotic listening, quantitative electroencephalography, or event-related brain potential measures have found differences between treatment responsive and nonresponsive subgroups of depressed patients. The neurophysiologic basis for these differences and the potential clinical utility of electrophysiologic and dichotic predictors of treatment outcome remain to be determined in future studies. 相似文献

This paper examines in detail the multitude of ways used by Jesus Movement organizations to raise money to fund their many activities. The research was provoked by sharp differences between fund‐raising methods used by the two largest and well known JM organizations—the Children of God (now called The Family) and Christ Communal Organization (a pseudonym for a group called Shiloh). The COG mainly relied on various forms of public solicitation, while Shiloh depended on working for others and themselves in an effort to become self‐supporting. Seven other JM groups were examined to find out what patterns of support were most prevalent, and to examine possible relationships between sustenance activities and theological developments within the groups. A large number of experimental approaches were taken by JM groups trying to sustain themselves during their sometimes tumultuous histories, leading to a number of general conclusions. 相似文献

Perceptual asymmetry differences between major depression with or without a comorbid anxiety disorder: a dichotic listening study. 总被引:3,自引:0,他引:3

Predictions that anxious and nonanxious depression would differ in perceptual asymmetry (PA), as well as in sensitivity for perceiving emotional words, were evaluated using dichotic listening tasks. A total of 149 patients having a major depressive disorder (51 with and 98 without an anxiety disorder) and 57 healthy controls were tested on fused-word and complex tone tasks. The anxious and nonanxious depression groups showed a consistent difference in PA across tasks; that is, the anxious group had a larger left-ear advantage for tones and a smaller right-ear advantage for words when compared with the nonanxious group. There was no group difference in sensitivity for perceiving emotional words. Patients having an anxious depression appear to have a greater propensity to activate right than left-hemisphere regions during auditory tasks, whereas those having a nonanxious depression have the opposite hemispheric asymmetry. 相似文献

A previous study showed that depressed patients who improved with tricyclic antidepressant medication had dichotic complex tones test results suggesting right-hemisphere dysfunction relative to nonresponders and controls (G. E. Bruder et al., 1990). A new sample of 68 depressed patients completed dichotic consonant-vowel (CV) and complex tones (CT) tests and then were treated with imipramine or placebo. A significant Ear x Test x Treatment x Response interaction was accounted for by significantly poorer left-ear accuracy for CVs among imipramine responders compared with nonresponders, placebo responders, and controls. CV left-ear accuracy was also significantly greater among placebo responders than placebo nonresponders and controls. The results only partially replicate the prior study in that evidence of right-hemisphere dysfunction in tricyclic responders was seen for the CV test but not the CT test. 相似文献
