Reversing the word-length effect: A comment on Caplan, Rochon, and Waters

Caplan, Rochon, and Waters (1992) report a failure to observe the poorer immediate serial recall for words of longer spoken duration obtained by Baddeley, Thomson, and Buchanan (1975) and subsequently replicated by others. Indeed, they find a significant reversal of this effect. We present evidence that the material used by Caplan et al. differs only minimally in spoken duration under speeded articulation conditions (Exp. 1 = 1.9%, Exp 2 = 2.31%), in contrast to a clear difference in the case of the original Baddeley et al. material (24.5%). It is further suggested that the reversal of the word-length effect may result from differences in acoustic similarity between the “long” and “short” word sets used by Caplan et al. We conclude that the evidence continues to indicate that longer spoken duration is associated with reduced memory span.     

Reassessing working memory: comment on Just and Carpenter (1992) and Waters and Caplan (1996)

M. A. Just and P. A. Carpenter's (1992) capacity theory of comprehension posits a linguistic working memory functionally separated from the representation of linguistic knowledge. G. S. Waters and D. Caplan's (1996) critique of this approach retained the notion of a separate working memory. In this article, the authors present an alternative account motivated by a connectionist approach to language comprehension. In their view, processing capacity emerges from network architecture and experience and is not a primitive that can vary independently. Individual differences in comprehension do not stem from variations in a separate working memory capacity; instead they emerge from an interaction of biological factors and language experience. This alternative is argued to provide a superior account of comprehension results previously attributed to a separate working memory capacity.     

Studies in space orientation. II. Perception of the upright with displaced visual fields and with body tilted.

To overcome certain disadvantages of the tilted-mirror situation as a technique for separating visual and postural determinants of the perceived upright, a new procedure was developed. The S was presented with a small tilted room, on the back wall of which was a rod which he had to adjust to the true upright. In a first test, judgments of the rod were obtained with body upright, and under three different conditions of the field: (a) The S, standing at a distance from the tilted scene, viewed it through a tube which restricted his view to the interior of the scene. (b) The S stood directly in front of the scene without a tube. (c) The S stood at a distance from the scene, without a tube, so that he saw not only the tilted scene but the outer upright room as well. Under all three conditions the perceived vertical and horizontal were displaced significantly in the direction of the axes of the tilted scene. When an outer upright field was present, as in the third condition, the effect of the tilted scene upon the perceived upright diminished. In another experiment, judgments of the rod were obtained with body tilted, both to the same side as the field and to the opposite side. It was found that tilting the body resulted in an increased tendency to accept the tilted field as a basis for judging the upright. Not only were the perceived vertical and horizontal displaced further in the direction of the tilted scene, but a number of Ss perceived the tilted scene as fully upright. In another experiment there was found a tendency for the tilted scene to right itself with prolonged observation. In some cases the righting was complete, so that at the end of the observation period, the tilted scene was perceived to be fully upright. Under all conditions, striking individual differences were found in the extent to which the perceived upright was affected by the surrounding tilted field. There is evidence of considerably consistency in a person's performance under the different conditions employed.     

Breaking the structuralist barrier. Literacy and numeracy with fluency.

Behavior analysis is an example of a selection science, and behavioral programs that follow the tenets of selectionism, long advocated by B. F. Skinner, can have a large impact on social problems. This article describes the characteristics of selection sciences and their application in the Morningside Model of Generative Instruction, which addresses both adult literacy and children's learning and attention problems. School curricula are analyzed for their key component elements and underlying tool skills. Teaching procedures then establish and build these key components to fluency. New and complex repertoires then emerge with little or no instruction, producing curriculum leaps that allow students to make rapid academic advancement. Children typically gain more than two grade levels per school year, and adults advance two grades per month.     

Coping with neck and low back pain in the general population.

This study had 2 objectives: (a) to assess the psychometric properties of the Pain Management Inventory (PMI; G. K. Brown & P. M. Nicassio, 1987) with individuals in the general population with neck or low back pain, and (b) to assess the relationship between pain severity and coping. Data were taken from a mailed survey of a random sample of adults residing in Saskatchewan, Canada. Results validated the 2-factor structure of the PMI and provided evidence for the internal consistency of the coping subscales. Regression analyses revealed that passive coping was associated with being married, greater pain severity, depression, and poor health. Active coping was associated with female gender, higher education, less depression, good health, and frequent exercise. This study provides psychometric data to support the use of the PMI and information about factors associated with use of active and passive coping strategies in pain sufferers.     

Attribution and expressed emotion in the relatives of patients with schizophrenia.

Indexes of expressed emotion (EE) in 58 relatives of patients with schizophrenia were related to those relatives' spontaneously expressed causal beliefs about the illness and about related symptoms and behaviors. Relatives made attributions predominantly to factors external, universal, and uncontrollable from their own perspective, and to factors internal, universal, and uncontrollable from the patient's perspective. Low-EE relatives were similar in their attributions to emotionally overinvolved relatives. Compared with these two groups, critical and/or hostile relatives made more attributions to factors personal to and controllable by the patient. Subsequent analyses suggested that hostile relatives were further characterized by making more attributions to factors internal to the patient and by making attributions with fewer causal elements.     

Arousal and activity level of rats with lesions in the dorsal hippocampus.

The effect on gross locomotor activity of irrelevant stimuli, prior exposure to these stimuli and two dosages of amphetamine were assessed on rats with lesions in the dorsal hippocampus. These animals were significantly more active post-operatively than sham-lesioned subjects. Prior exposure to the irrelevant stimuli increased post-operative differentiation between stimuli, whereas the introduction of amphetamine had the reverse effect. Changes in locomotor activity occurred at lower dosages of amphetamine than in previous studies, suggesting that the irrelevant stimuli have an arousal effect which acts additively with amphetamine and hippocampal impairment.     

Choice in the time-left procedure and in concurrent chains with a time-left terminal link.

In two experiments, rats chose between a standard fixed-duration food-associated stimulus and a stimulus whose duration was the time remaining to reinforcement in an elapsing comparison interval. In Experiment 1, 4 rats responded in a time-left procedure wherein a single initial-link variable-interval schedule set up two potential terminal links simultaneously. As time elapsed in the initial-link schedule, the choice was between a standard fixed-interval 30-s terminal link and a time-left terminal link whose programmed interval requirement equaled 90 s minus the elapsed time in the initial link. Rats generally responded more on the lever with the shortest programmed terminal-link duration, but the temporal parameters of the procedure were found to vary with response distributions. Contrary to previous reports, therefore, time-left data were well predicted by choice models that make no assumptions about animal timing. In Experiment 2, 8 rats responded on a concurrent-chains schedule with independent variable-interval initial links and a time-left terminal link in one of the choice schedules. On the time-left lever, the programmed terminal-link delay equaled 90 s minus the elapsed time in the time-left initial link. On the standard lever, terminal-link responses were reinforced according to a variable-interval schedule whose average value varied over four conditions. Relative time-left initial-link responses increased in the elapsing time-left initial-link schedule as the time-left terminal link became shorter relative to the standard terminal link. Scalar expectancy theory failed to predict the resultant data, but a modified version of the delay-reduction model made good predictions. An analysis of the elaboration of scalar expectancy theory for variable delays demonstrated that the model is poorly formulated for arithmetically distributed delays.     

Characterizing the musical phenotype in individuals with Williams Syndrome.

Williams Syndrome (WS), a neurodevelopmental genetic disorder, is characterized by peaks and valleys in mental function: substantial impairments in cognitive domains such as reasoning, arithmetic ability, and spatial cognition, alongside relatively preserved skills in social domains, face processing, language, and music. We report the results of a comprehensive survey on musical behaviors and background administered to the largest sample of individuals with WS to date (n = 118, mean age = 20.4), and compare the results to those obtained from a control group of typically developing normal individuals (n = 118, mean age = 20.9) and two groups of individuals with other neurodevelopmental genetic disorders, Autism (n = 30, mean age = 18.2) and Down Syndrome (n = 40, mean age = 17.2). Individuals with WS were found to be rated higher in musical accomplishment, engagement, and interest than either of the comparison groups, and equivalent on most measures to the control group. Compared to all other groups including the controls, the WS individuals displayed greater emotional responses to music, manifested interest in music at an earlier age, and spent more hours per week listening to music. In addition, the effects of music listening (whether positive or negative) tended to last longer in the WS group. A factor analysis extracted seven principal components that characterize the musical phenotype in our sample, and discriminant function analysis of those factors was able to successfully predict group membership for the majority of cases. We discuss the neurobiological implications of these findings.

Splitting and ambivalence. On the therapeutic dilemma in treating patients with early damage

The article refers to the pathological problem of severe psychic disturbed patients (with: borderline syndromes/pathological narcism/character neurosis/basic faults and/or disorders of ego structure). The author refers to countertransferences and acting out of affects and reports on the changes and possibilities in the therapy of these patients. The therapists fundamental attitude will be described and supplemented by favouring a treatment in day-hospital-settings. Basic literature has been compiled and is reported as survey.     

The role of neuropsychology in the assessment and treatment of persons with epilepsy.

Several areas of current interest in the neuropsychology of epilepsy are briefly reviewed in this article. These include variables pertaining to seizures, seizure history, antiepileptic drugs, and methods of neuropsychological evaluation. It is apparent that epilepsy is a multifaceted area: Psychologists not only can be of great assistance to patients with this condition, but may also learn a great deal from this complex disorder.
