The Psychological Record - By avoiding the confound between the physical and semantic properties of words, it was possible to demonstrate the effects and aftereffects of semantic satiation....     

Galef’s Transfer-of-Information Effect Occurs in a Free-Foraging Situation

Galef and his colleagues have repeatedly shown that one rat may transfer information regarding the type of food it has consumed to other conspecifics. Such experiments typically have been conducted in wire-mesh cages or a wooden maze. The present experiments sought to extend this paradigm to the open-field foraging situation having six food patches to choose from. Following interaction with a demonstrator that had consumed either a cocoa or a cinnamon diet, single observers (Experiment 1) were tested in the foraging situation. Food-consumption scores indicated that observers consumed significantly more of their specific demonstrator’s diet than a second diet that was available also. Experiment 2 involved the simultaneous testing of two observers in the foraging laboratory. In Experiment 3 two observers were once again tested, but each had been provided a different food-type message prior to foraging. Positive results, mirroring those of Experiment 1, were obtained in both Experiments 2 and 3. The results of these three experiments underscore the robustness of this phenomenon and its generalizability to other testing conditions.

     

Anomalous dominance in sibling stutterers: Evidence from CT scan asymmetries, dichotic listening, neuropsychological testing, and handedness

Two left-handed siblings with developmental stuttering are comprehensively described. The methods of study included speech and language evaluation, neurological and neuropsychological examinations, dichotic listening, auditory evoked responses, electroencephalogram, and CT scan asymmetry measurements. The data from each sibling showed evidence of anomalous cerebral dominance on many of the variables investigated. The CT scan measurements showed atypical asymmetries, especially in the occipital regions. These findings support the theory that stuttering may be related to anomalous cerebral dominance, both on functional as well as structural bases. Implications of anomalous dominance and the resultant effect of hemispheric rivalry on speech fluency are discussed.     

Work site group meetings and the effectiveness of a televised smoking cessation intervention

At the work site, smoking accounts for increased health care expenses and worker absenteeism due to smoking-related illness and reduced productivity and lost wages. Developing comprehensive and accessible smoking cessation programs at the work site is an important objective for health care professionals. In this study, employees of 43 corporations participated in a televised smoking cessation program accompanied by self-help manuals. The media component involved presenting a smoking cessation program on a network television affiliate station during the 4:30 p.m. and 10:00 p.m. news for 20 days. Employees at half the corporations also had access to semiweekly self-help group meetings. Adding self-help support groups to a program involving self-help manuals and the media reports was found to significantly increase abstinence and its maintenance over time. The implications of using the media, self-help groups, and work site locations in large-scale community-based interventions are discussed.     

The word frequency effect in lexical decision: Finding a frequency-based component

Subjects making lexical decisions are reliably faster in responding to high-frequency words than to low-frequency words. This is known as the word frequency effect. We wished to demonstrate that some portion of this effect was due to frequency differences between words rather than to other dimensions correlated with word frequency. Three groups of subjects (10 engineers, 10 nurses, and I0 law students) made lexical decisions about 720 items, half words and half nonwords, from six different categories (engineering, medical, low-frequency nontechnical, medium-frequency nontechnical, and two groups of high-frequency nontechnical). Results of two analyses of variance revealed a crossover interaction such that engineers were faster in responding to engineering words than to medical words, whereas nurses were faster in responding to medical words than to engineering words. The engineering and medical words were equally long and equally infrequent by standard word counts. We take this as support for a frequency-based component in the word frequency effect. The practical implications of this research for estimating the readability of technical text are discussed.     

Do you really want to maintain that a flat tire can upset your stomach? Using the findings of the psychophysiology of stress to bolster the argument that people are not directly disturbed by events

The purpose of this paper is to help clients and others more fully appreciate the complex chain of events intervening between an external happening and an emotional response to that happening. It deals first with the sensory processing of physical stimulation and then presents the current state of knowledge regarding stress psychophysiology. A decision by the cortex which defines something as dangerous or threatening activates two major stress reaction pathways, the endocrine system and the autonomic nervous system, with a large number of physical consequences such as: acceleration of heart rate, increased blood pressure, reduced effectiveness of the immunological system, slowing of gastro-intestinal processes, pupil dilation, bronchial dilation and inhibition of salivation. The complexity and variety of such consequences is illustrated with a series of flow-chart diagrams, and it is suggested that these can be an additional and persuasive argument for the RET position which follows the claim of Epictetus: People are disturbed not by things, but by the views they take of them. Finally it is argued that while rapid emotional responses oftenseem to occur automatically it is because the intervening cortical processes are at times not verbalized. This is shown in the context of a diagrammatic outline of the Rational-Emotive Therapy process.Paul J. Woods, Ph.D., co-editor of this journal, is an associate fellow and an RET training supervisor of the Institute for Rational-Emotive Therapy.     

Ethical dilemmas in forensic evaluations

Ethical issues emerging from forensic assessments are addressed from clinical and research perspectives. The relevance of agency, forensic identification, and attitudes toward defendants are explored within the framework of ethical practice. Finally, the ethical role of mental health professionals in the courtroom, the scope and basis of their testimony, and the rendering of conclusory opinions are discussed within a psycholegal context.     

An introduction to organic brain syndromes

Organic brain syndromes are of forensic interest for several reasons. First, patients with organic brain syndromes may require judicial determination of competence in any of a number of areas, e.g., testamentary capacity, need for financial guardianship, or competence to make medical decisions. Second, any patient whose mental state is of legal interest will need evaluation for contributing organic factors; uncovering these factors may have considerable medical and legal consequence. Third, the discovery of organic factors may be decisive in the outcome of a judicial proceeding, where “hard” biological data are often accorded more weight, and are thus more persuasive, than “soft” psychological data. This article provides an introductory overview of the organic brain syndromes. For each syndrome, the clinical features are described and are illustrated with a case vignette, the more common etiologies are presented, and selected aspects to the evaluation are highlighted. In addition, since the detectian of malingered mental illness is a key component in many forensic contexts, characteristics are described which help to distinguish actual from malingered mental illness.     

The effects of perceived parental rearing style on the development of Type A pattern

The aetiological antecedents of the Type A pattern have not been studied widely. In the present study the effects of parental rearing practices on the development of Type A pattern were evaluated. Perceived parental rearing style was assessed by the EMBU and Type A pattern by the JAS. Subjects were drawn from a random sample of residents (older than 21 years) of a Dutch community. Results suggested that a significant amount of variance of Type A behaviour can be accounted for by perceived parental characteristics, especially rejection and lack of emotional warmth. It is suggested that lack of emotional warmth and negative evaluation of children by their parents may lead to an internalized maladaptive cognitive set in the children which may be a developmental antecedent for eliciting the competitiveness, achievement striving, and sense of time urgency characteristic of Type A adults.     

Reasons for employee sabotage in the workplace

Unionized workers at a factory were asked to rate a variety of reasons which would justify the use of sabotage in an organization, as well as the justifiability of four general methods of sabotage (slowdowns, destructiveness, dishonesty, and causing chaos). Results showed that as compared to those who didn't accept a wide variety of reasons for sabotage, those who accepted a variety of reasons would more readily justify all forms of sabotage except dishonesty. The data is discussed in terms of the reasons for the lack of justification that dishonesty receives, as well as future directions for the study of sabotage.
