Behavior of neonates exposed in utero to methadone as assessed on the Brazelton scale

Twenty-nine infants exposed in utero to methadone and 37 comparison infants were examined on the Neonatal Behavioral Assessment Scale at early and late neonatal ages. All infants were full-term at birth, over 2500 g, and not yet circumcised at the early assessment. None of the methadone-exposed infants were breast-fed or were being treated pharmacologically for withdrawal. During the first week of life, methadone-exposed neonates differed from comparison ones in motoric behavior. Relative to comparison-group infants, they were jerkier and more tremulous, tense, active, and better able to put hand in mouth. By the end of the first month these differences diminished, although there was still a tendency for the methadone-exposed infants to have elevated body tonus. Neither perinatal complications, birth weight, nor sex of infant could explain the early neonatal differences between the methadone and comparison groups. Past the early stage of acute withdrawal, neonates exposed prenatally to methadone behave not unlike their nonexposed peers.     

Development of lateral asymmetry in the perception of sequentially touched fingers

In order to investigate lateral asymmetry in tactile perception, two or four fingers of normal primary school children were touched sequentially. Stimulation was either unimanual or bimanual and either verbal or nonverbal responses were required. Right hand advantage was demonstrated subsequent to uni- and bimanual stimulation in both the verbal and nonverbal response conditions. Neither an age nor a sex effect on laterality was found. Right hand advantage was affected by direction of stimulation in the bimanual condition. Left hemispheric dominance was argued to be related to the temporal nature of the tasks.

On various causes of improper solutions in maximum likelihood factor analysis

In the applications of maximum likelihood factor analysis the occurrence of boundary minima instead of proper minima is no exception at all. In the past the causes of such improper solutions could not be detected. This was impossible because the matrices containing the parameters of the factor analysis model were kept positive definite. By dropping these constraints, it becomes possible to distinguish between the different causes of improper solutions. In this paper some of the most important causes are discussed and illustrated by means of artificial and empirical data.The author is indebted to H. J. Prins for stimulating and encouraging discussions.     

Treatment of obsessive-compulsive patients: The contribution of self-instructional training to the effectiveness of exposure

Fifteen obsessive-compulsive patients were given treatment consisting of ten sessions of gradual exposure in vivo. For half of the patients gradual exposure in vivo was preceded by self-instructional training.Treatment resulted in significant improvement on anxiety and avoidance scales, Leyton Obsessional Inventory, Self-rating Depression Scale and on ratings for anxious mood and depression. Neither the post-test nor the follow-ups 1 month and 6 months later indicated a difference between the effects of the two conditions. Self-instructional training did not enhance the effectiveness of gradual exposure in vivo.     

Treatment indication in psychotherapy: Some methodological aspects

In this paper it is argued that the general problem of indication, increasingly discussed in the field of psychotherapy in recent years, actually is a pseudoproblem with no solution to be expected. In its objectives and premises it is trongly suggestive of conceptions and ideas of early logical empiricism, to be considered as out-of-date today. The concept of indication is identified as ambiguous, and preliminary remarks aiming at an explication of the concept are made. Finally, the consequences of our arguments for the immediate problem of integration of the different therapeutic approaches are pointed out.     

BEHAVIOR THERAPY AND THE CONDITIONING MODEL OF NEUROSIS

The methods of applied science are usually based on the findings of pure science, and the discovery of successful methods of therapy for the neuroses is dependent on the formulation of appropriate theories for these disorders. It is argued that the only viable theory about neurosis at the moment is an adaptation of the Watsonian conditioning model, suitably altered to fit in with more recent discoveries in the fields of the formation and extinction of conditioned responses. Such a model has important relevance to behaviour therapy and the various methods for treating neuroses falling under that heading, and indeed for an explanation of the apparent effectiveness of psychotherapy, psychoanalysis, and whatever events mediate spontaneous remission.
