The effects of parental alcoholism on perception of control and imposter phenomenon

The present study examined the differences in internal and external locus of control and imposter phenomenon among persons with alcoholic and non-alcoholic parents. The subjects were 48 college students and 21 members of local Adult Children of Alcoholic groups. The students were further divided into those with alcoholic parents and non-alcoholic parents. The subjects were administered the following three instruments: the Nowicki-Strickland Internal-External Control Scale for Adults (Nowicki & Duke, 1973), the Imposter Test (Chance & O’Toole, 1987), and a family history survey. Analysis of locus of control scores revealed a highly significant (p<.01) difference for externality, with Adult Children being most external and students with non-alcoholic parents least external. Similarly, internality scores differed significantly (p<.0001), with Adult Children being least, and the non-alcoholic group being most internally oriented. Analysis of variance for imposter phenomenon revealed a significant (p<.05) difference among the three groups, with the Adult Children of Alcoholics group having the highest scores and students with non-alcoholic parents having the lowest. These findings are consistent with the idea that parental alcoholism interferes with nurturing and consistent reinforcement, and with the development of personal adaptability.     

Child sexual abuse allegations during custody litigation: Conflicts between mental health expert witnesses and the law

This article describes (1) an intrafamilial child sexual abuse case and (2) the multidisciplinary research project which developed from its outcome. The research project., in existence since 1987, is a task force of the Committee an Children, Youth, and Families of the New Jersey Psychological Association and is co-sponsored by the Committee on Child Psychiatry of the New Jersey Psychiatric Association. The research aims at developing an objective behavioral assessment instrument to validate child sexual abuse allegations, and at achieving a clinical-legal consensus regarding the credibility of the instrument. Ranking, reliability, and validity studies are described.     

Analogical transfer and expertise in legal reasoning

Analogical transfer and its relation to expertise is examined in a legal context. Three experiments were conducted comparing the performance of novices (introductory tax students) and of experts (experienced tax practitioners from multinational public accounting firms) on tasks involving the application of tax laws. In Experiment 1 subjects completed a target problem after reading a decided case that was either analogous or not analogous to a target problem. A limited amount of transfer was observed, with no differential rate of transfer across experience levels. In Experiments 2 and 3 attempts were made to facilitate transfer of knowledge by inducing transfer-appropriate processing of the source analog and by providing multiple source analogs. The results of both experiments indicate an interaction between treatment and expertise. Unexpectedly, the facilitating treatments reduced the transfer of knowledge for experts while increasing the transfer for novices. Subsequent analysis of the responses of the expert subjects indicates that for the more experienced expert subjects a highly proceduralized rule interfered with the knowledge transfer when that rule was made salient by the facilitating treatments. The less experienced expert subjects behaved in a manner consistent with the hypotheses. This poor performance of the more experienced experts results from the inflexibility in expert problem solving due to the proceduralization of information processing. Frensch and Sternberg (1989) demonstrate that this type of inflexibility is one of the costs of expertise and results from the development of a large and highly complex knowledge base containing numerous well developed strategies.     

Massignon,Vatican II and Islam as an Abrahamic religion

The qur'anic material about Abraham corresponds in broad outline to the biblical story although it contains some novel features, including the claim that Islam is the religion of Abraham and that together with Ishmael he rebuilt the Kaaba. The article surveys the largely negative responses of Byzantine polemicists, medieval Western authors, and later orientalists, to Islam's avowedly Abrahamic pedigree. It then examines the work of Louis Massignon and his circle, and discusses the extent to which his conviction that Islam was an Abrahamic religion, like Judaism and Christianity, influenced Vatican II. Some precursors of Massignon are mentioned, his attitude to the qur'anic representation of Abraham is criticized in the light of recent research, and his interest’ in Abraham is shown to have been intimately bound up with the peculiar circumstances of his own life.     

Properties of the diffuse thalamocortical system, human intelligence and differentiated vs integrated modes of learning

In complementary reports Robinson (1982a, b) describes how the transmission characteristics or time constants of thalamic and cortical neuron populations of the diffuse thalamocortical system (DTS) can be evaluated in human subjects. Equating these constants with the Pavlovian property of ‘strength’ it was predicted that they should relate to Extraversion and Neuroticism scores on the Eysenck Personality Questionnaire (EPQ). This prediction was confirmed and the results provide direct support for the theories of Pavlov and Eysenck. The present report describes additional results which confirm predictions relating the DTS constants to performance on the Wechsler Adult Intelligence Scale (WAIS) and on the Embedded Figures Test (EFT). An important finding was that a measure of deviation from intermediate and ‘balanced’ values of the DTS constants loads to the extent of -0.80 on the WAIS ‘memory’ or ‘attention/ concentration’ factor. More generally, the results provide further support for Pavlov's conception of brain-behaviour relationships and suggest that the DTS plays a fundamental role in determining a broad spectrum of human psychological differences including some associated with the concepts of intelligence and cognitive style. These IQ and cognitive style differences are explained as the immediate and longer-term consequences, respectively, of differences in the distribution of background cortical activity mediated by the DTS.     

The processing of fundamental frequency in a dichotic matching task

The temporal characteristics of auditory memory were investigated using a reaction time paradigm. The study attempted to determine whether or not there are functionally distinct left and right hemisphere components of auditory memory with different capacities for the retention of nonlinguistic information, such as fundamental frequency, over the course of several seconds. The results indicated that fundamental frequency information in auditory memory remains substantially unchanged over the course of 2 sec. No evidence was found for the existence of separate left and right hemisphere components of auditory memory with different temporal characteristics. The implications of this finding for the organization of auditory memory in the brain are discussed.     

Impairment of nonverbal oral movements in aphasia

Thirty-six patients with unilateral cerebral vascular damage were required to perform a number of oral motor tasks, both verbal and nonverbal. Nonfluent aphasics were impaired in the imitation of single oral movements, as previously reported. However, on the imitation of complex nonverbal oral movements fluent aphasics were impaired as well as nonfluents. This impairment was not explicable on the basis of visual memory or perceptual deficits, nor on the basis of sensory thresholds as measured on the tongue. The findings suggest that deficits in coordinating oral movements are fundamental to most aphasic impairments, the meaningfulness of the responses not being a critical factor in the appearance of the defect.     

Biasing power law exponents by magnitude estimation instructions

This study investigates the influence of attention loading on the established intersensory effects of passive bodily rotation on choice reaction time (RT) to visual motion. Subjects sat at the center of rotation in an enclosed rotating chamber and observed an oscilloscope on which were, in the center, a tracking display and, 10° left of center, a RT line. Three tracking tasks and a no-tracking control condition were presented to all subjects in combination with the RT task, which occurred with and without concurrent cab rotations. Choice RT to. line motions was inhibited (p < .001) both when there was simultaneous vestibular stimulation and when there was a tracking task; response latencies lengthened progressively with increased similarity between the RT and tracking tasks. However, the attention conditions did not affect the intersensory effect; the significance of this for the nature of the sensory interaction is discussed.     

A color aftereffect contingent on complex pattern features

It was shown that a McCollough-type color aftereffect could be induced using a pair of patterns each of which contained lines of many orientations (radial lines and concentric circles). That is, the two patterns appear to be color adapted independently. The effect could simply be a new version of the McCollough effect facilitated by a tendency to fixate the centers of the patterns. Also, the size features of the displays could be used as the basis of a spatial frequency analyzer explanation. Experimental data were used to test both of these suggestions, but very little support was found for either. It was therefore suggested that the major basis of the effect was the color adaptation of “curvature analyzers.”
