A Cybernetic Theory of Psychopathology

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.     

Assessing At‐Risk Youth Using the Reynolds Adolescent Adjustment Screening Inventory With a Latino Population

Factor analyses were conducted on scores from the Reynolds Adolescent Adjustment Screening Inventory (RAASI; Reynolds, 2001 ) representing at‐risk Latino youth. The 4‐factor model of the RAASI did not exhibit a good fit. However, evidence of generalizability for Latino youth was noted.     

Misconstruing methods and meaning in the General Factor of Personality

Research has suggested that a General Factor of Personality (GFP) might represent a real and meaningful higher‐order factor in the personality hierarchy. However, there are psychometric shortcomings in many of the studies used to support this argument, as well as convincing empirical evidence for alternative explanations of the GFP as methodological rather than meaningful. The current article re‐examines the research supporting a substantive GFP by considering and evaluating the evidence presented in a recent volume (Just, 2011). It is concluded that covariation among first‐order personality factors is more likely a statistical or methodological artefact than a theoretically meaningful higher‐order construct.     

Improving Children's Mental Rotation Accuracy With Computer Game Playing

The authors investigated the relation between mental rotation (MR) and computer game-playing experience. Third grade boys (n = 24) and girls (n = 23) completed a 2-dimensional MR test before and after playing computer games (during 11 separate 30-min sessions), which either involved the use of MR skills (the experimental group) or did not involve the use of MR skills (the control group). The experimental group outperformed the control group on the MR posttest but not on the pretest. Boys outperformed girls on the pretest but not on the posttest. Children whose initial MR performance was low improved after playing computer games that entailed MR skills. The findings imply that computer-based instructional activities can be used in schools to enhance children's spatial abilities.     

The Effect of Differential Post-Weaning Environment on the Rigidity of an Animal's Behavior

Seventy-two first, second and third grade boys and girls were administered seriation problems involving different combinations of shape and color variation. Success rates and latency scores were influenced by shape variation, but not by color variation or grade level. The failure to obtain predicted interactions between the effects of grade level and stimulus variation was attributed to the clarity of the relevant stimulus dimension.     

The Effect of Mental Practice on Performance in a Sequential Reaction Time Task

The effect of mental practice on performance in a dot-location RT task was investigated. Participants (N = 40) were required either to mentally practice, physically practice, or do no practice on an RT task in which the signals appeared in a repeating sequence. Correct mental practice, as opposed to incorrect mental practice and no practice, was predicted to have a positive (enhancing) effect on performance of the RT task. Despite previous evidence that mental rehearsal does enhance performance in many perceptual-motor tasks, neither correct nor incorrect mental rehearsal affected subsequent sequence learning; that is, no mental practice effect was observed. That surprising result is discussed in terms of motivational, psychoneuromuscular, separate memory systems, and transfer-appropriate processing explanations of mental practice.     

Quantification of Electroencephalography

In Experiment 1, a study by Messer was replicated with use of 18 children aged 40 to 67 months and nonsense words in which the phonemes of the consonant onsets of permissible and impermissible words were equated for frequency of occurrence. The children did not choose significantly more permissible words at any age, indicating that they did not use phonological rules as a basis for choice. In Experiment 2, similar materials were used with 14 children aged 56 to 74 months. By means of an operant conditioning procedure and a learning set paradigm, an experimental group (five children) was reinforced for choosing the permissible member of 10 permissible/impermissible pairs of nonsense words to a criterion of 80 percent correct responses. On transfer to a test task (16 problems given at a rate of 12 trials per problem) the group reached a mean performance level of 76 percent correct responses, which was significantly greater than that attained by either of two control groups (nine children). It was therefore concluded that some evidence for the existence of implicit phonological rules had been obtained, although the conclusion had to be qualified because (a) the mean level of performance of the experimental group during the test task was relatively low, and (b) because only children with high 1Qs performed at a level better than chance.     

Occupational Choices for People with Psychiatric Disabilities: Comparing Attendees and Non-Attendees at Community-Based Day Centers

Research has shown that people with psychiatric disabilities who attend a day center rate their satisfaction with daily occupations equally in comparison with non-attendees. The current study investigates which occupations the target group performs and also differences in occupational choices between attendees and non-attendees. Reported occupations were analyzed with content analysis. Day center attendees reported more productive occupations, while non-attendees reported more recreational occupations and a greater breadth of occupations. This implies that non-attendees might compensate a lack of work-like occupations at a day center with satisfying recreational occupations. The results can guide development of psychiatric occupational-based rehabilitation.
