Abstract

Cybernetics, the study of principles governing goal-directed, self-regulating systems, offers a useful approach to understanding psychopathology or psychological dysfunction, overcoming limitations of other naturalistic approaches. Whereas influential theories of psychopathology have relied on definitions of dysfunction rooted in evolution and fitness, we define psychopathology in terms of cybernetic dysfunction, failure to make progress toward important goals. Cybernetic function in organisms is not identical to evolutionary function, despite their causal phylogenetic relationship. We define psychopathology as persistent failure to move toward one’s goals, due to failure to generate effective new goals, interpretations, or strategies when existing ones prove unsuccessful. This definition allows a thorough integration of dimensional approaches to psychopathology and personality and provides a new perspective on the nosology of mental disorder. We review evidence that the major dimensions of psychopathology correspond to major trait dimensions of personality, but we assert that extremity on these dimensions is neither necessary nor sufficient for psychopathology, which requires cybernetic dysfunction. Drawing from psychological and neurobiological research on personality and psychopathology, we present a theory of the mechanisms underlying the five major dimensions of psychopathology, some of their subdimensions, and the general risk factor for psychopathology. We conclude by discussing implications of our theory for research, diagnosis, and mental health interventions.  相似文献

This study investigated cultural variations in perceived control over personal goals in Russian and American college students. Several appraisal dimensions of personal goals were studied including goals’ importance, their attainability, and sources of control over goal attainment, such as self, others, luck, and fate. The association between assimilative (tenacious goal pursuit) and accommodative (flexible goal adjustment) control strategies and perceived attainability of goals was also examined. The results indicated that both Russian and American students gave higher priority to work‐ and education‐related goals and lower priority to the familial goal. In both samples, the familial goal was the most influenced and health was the least influenced by luck/chance and fate. Overall, American students were more optimistic about the perceived probability to attain their goals, which may be affected by a cultural tendency for self‐enhancement and positive outlook. Russian students had a stronger belief in control by luck/chance and fate over personal goals, which coincides with a less agentic orientation of Russian culture. Regardless of culture and goal content, goal importance was associated with greater perceived success in goal attainment. However, control strategies (assimilative and accommodative) as well as internal control differentially predicted perceived attainability of goals depending on the goals’ content. For both Russians and Americans, perceived attainability of education‐related goals was associated with assimilative strategies and internal control; leisure was associated with accommodative strategies and health‐related goals were associated with internal control. Characteristics of cultural contexts accountable for crosscultural differences in perceived control over personal goals are discussed.  相似文献

In this study, the author examines the effect of attentional control and heart-period variability on measures of negative affect and trait anxiety in undergraduate students. Baseline heart rate was recorded from 119 participants within a laboratory setting. Spectral analysis was used on the heart-rate data to isolate the parasympathetic contribution to the cardiac pattern. Participants completed measures of negative affect, attentional control, and trait anxiety following the recording of heart rate. Regression analysis indicated that high negative affect, low attentional control, and reduced parasympathetic tone were significant predictors of high trait anxiety. Subsequent regression analysis pointed toward the interaction of attentional control and parasympathetic tone in influencing self-rated measures of negative affect. Results highlight the importance of attentional control and parasympathetic tone as regulatory mechanisms related to self-rated estimates of negative affect and trait anxiety.  相似文献

The left and right hemispheres of the brain are differentially related to the processing of emotions. Although there is little doubt that the right hemisphere is relatively superior for processing negative emotions, controversy exists over the hemispheric role in the processing of positive emotions. Eighty right-handed normal male participants were examined for visual-field (left-right) differences in the perception of facial expressions of emotion. Facial composite (RR, LL) and hemifacial (R, L) sets depicting emotion expressions of happiness and sadness were prepared. Pairs of such photographs were presented bilaterally for 150 ms, and participants were asked to select the photographs that looked more expressive. A left visual-field superiority (a right-hemisphere function) was found for sad facial emotion. A hemispheric advantage in the perception of happy expression was not found.  相似文献

It is suggested that the popular definition of foot dominance (i.e., the limb preferred to execute a manipulative or mobilizing action while the other [nondominant] foot provides stabilizing support, e.g., kicking a ball) be reconsidered in light of understanding the functional characteristics of footedness and selected theoretical explanations. Relevance to future research designs and assessment methodology is discussed.  相似文献

The authors investigated the ability of children with emotional and behavioral difficulties, divided according to their Psychopathy Screening Device scores (P. J. Frick & R. D. Hare, in press), to recognize emotional facial expressions and vocal tones. The Psychopathy Screening Device indexes a behavioral syndrome with two dimensions: affective disturbance and impulsive and conduct problems. Nine children with psychopathic tendencies and 9 comparison children were presented with 2 facial expression and 2 vocal tone subtests from the Diagnostic Analysis of Nonverbal Accuracy (S. Nowicki & M. P. Duke, 1994). These subtests measure the ability to name sad, fearful, happy, and angry facial expressions and vocal affects. The children with psychopathic tendencies showed selective impairments in the recognition of both sad and fearful facial expressions and sad vocal tone. In contrast, the two groups did not differ in their recognition of happy or angry facial expressions or fearful, happy, and angry vocal tones. The results are interpreted with reference to the suggestion that the development of psychopathic tendencies may reflect early amygdala dysfunction (R. J. R. Blair, J. S. Morris, C. D. Frith, D. I. Perrett, & R. Dolan, 1999).  相似文献

Two samples, one gifted, the other “normal,” of 30 children each (11 to 13 years of age) were matched on age, sex, race, and father's occupation. A parent of each child completed the Children's Behavioral Classification Project instrument, and a profile of 30 scaled scores was obtained for each protocol. A discriminant analysis on the basis of the profiles classified 50 of the 60 Ss correctly into their respective sample category, either gifted or normal. Though the results of a multivariate analysis of variance showed no significant differences between the groups when the 30 profile factors were viewed as a whole, univariate analyses on the separate factors yielded significant group differences on several related factors. These were interpreted with caution. Additional factors displayed significant sex differences and one demonstrated a group-by-sex interaction effect.

Coefficients of pattern similarity (the rp ) were computed among all pairs of the 60 Ss. An unweighted average linkage cluster analysis grouped 34 of the 60 Ss into six clusters which accounted for 26 of 30 possible gifted children.

After an item analysis was performed on the original data, a 42 item subscale of the CBCP questionnaire was constructed which correctly classified 31 of 40 individuals in a cross-validation sample.  相似文献

We assessed the relation between the empathic responsiveness of young adults and the relative frequency and intensity of distressful events they experienced as children. Undergraduate subjects (N = 111; 56 men and 55 women) were led to believe that they were participating in two separate studies. In the first study, students completed the Distress Experiences in Childhood questionnaire, a filler task, and a slightly abbreviated version of the Mehrabian and Epstein (1972) empathy measure. In the second study, students watched an emotion-laden videotape of a patient (actually an actress) in a therapy session and subsequently completed an emotional-response questionnaire adapted from Batson, O'Quin, Fultz, Vanderplas, and Isen (1983). Students who rated their distressful childhood experiences as highly distressing scored higher on both measures of empathy than did students who rated their experiences as relatively less distressing. In contrast, the number of distressful childhood experiences reported was generally unrelated to empathy scores.  相似文献

In this study the authors investigated associations among children's observed responses to failure in an analogue entry situation, their attention deployment patterns, and skills and processes associated with self-regulation. Participants were 54 kindergarten and first-grade students who were either aggressive-rejected or low aggressive-popular based on peer nominations. Inhibitory control predicted the tendency to respond to entry failure by stopping and watching the group's activity. Baseline vagal tone and other-directed attention predicted children's tendency to change entry strategies after failure. Parent-rated attention skills moderated the relation between children's attention deployment patterns during the entry task and their responses to entry failure. Children who engaged in more other-directed attention were less likely to turn to solitary play after entry failure but only if they had high or moderate levels of attentional control. Other-directed attention was related to repeating previous entry bids without modification after entry failure but only when children had high levels of attention problems.  相似文献

In the present work the effect of two task variables on transfer were studied: shape of the track-circular or triangular; and target speed-constant or variable. One or both of these variables was changed on transfer. Experimental conditions were (a) 10 preshift and 10 post-shift trials, and (b) 20 single-trial alternations of two tasks. 22 groups of 12 Ss each were tested. Condition (a) showed positive transfer with single variable change and zero or negative transfer with simultaneous change in two variables, and condition (b) annulled all transfer effects. Results are discussed in terms of commonality between tasks and receptor and perceptual anticipation.  相似文献
