Differences in memory functioning between children with attention-deficit/hyperactivity disorder and/or focal epilepsy

Prior research has shown that attention-deficit/hyperactivity disorder (ADHD) and epilepsy are frequently comorbid and that both disorders are associated with various attention and memory problems. Nonetheless, limited research has been conducted comparing the two disorders in one sample to determine unique versus shared deficits. Hence, we investigated differences in working memory (WM) and short-term and delayed recall between children with ADHD, focal epilepsy of mixed foci, comorbid ADHD/epilepsy and controls. Participants were compared on the Core subtests and the Picture Locations subtest of the Children’s Memory Scale (CMS). Results indicated that children with ADHD displayed intact verbal WM and long-term memory (LTM), as well as intact performance on most aspects of short-term memory (STM). They performed worse than controls on Numbers Forward and Picture Locations, suggesting problems with focused attention and simple span for visual-spatial material. Conversely, children with epilepsy displayed poor focused attention and STM regardless of the modality assessed, which affected encoding into LTM. The only loss over time was found for passages (Stories). WM was intact. Children with comorbid ADHD/epilepsy displayed focused attention and STM/LTM problems consistent with both disorders, having the lowest scores across the four groups. Hence, focused attention and visual-spatial span appear to be affected in both disorders, whereas additional STM/encoding problems are specific to epilepsy. Children with comorbid ADHD/epilepsy have deficits consistent with both disorders, with slight additive effects. This study suggests that attention and memory testing should be a regular part of the evaluation of children with epilepsy and ADHD.     

Prayer as a model of communication

The paper deals with the principles of good communication between persons, taking the traditional forms of prayer—confession, petition, praise, thanksgiving, and contemplation—as models. It is divided into two sections: The first presents the principles of poor communication and sets these within a theological context, followed by the principles of good communication; the second section suggests two practical applications of this material: (1) marriage counseling by Christian pastors, and (2) a short, Christian education course.Sylvia Fleming Crocker has a Ph.D. in philosophy and an M.A. in comparative religion.

The Equity-Control Model as a Predictor of Vandalism Among College Students1

The equity-control model of vandalism (Baron & Fisher, 1984; Fisher & Baron, 1982) is used to conceptualize vandalism among college students. The model predicts that vandalism is most likely where there are low perceived equity (perceived lack of fairness in one's social or environmental arrangements) and low to moderate perceived control (perceived inability to effectively modify outcomes and arrangements). To test the model, university students were given questionnaires which measured perceived equity and control as these factors relate to the university and to dormitory living. Using multiple regression analysis, the interaction of equity and control was predictive of vandalism: Subjects with low perceived equity and control were most likely to report they engaged in vandalistic acts.     

Gender differences in causal attributions by college students of performance on course examinations

Gender differences in causal attributions and emotions for imagined success and failure on examinations were investigated. Males made stronger ability attributions for success than females, whereas females emphasized the importance of studying and paying attention. Males more than females attributed failure to a lack of studying and low interest, but females were more likely than males to blame an F on a lack of ability. Females experienced stronger emotions than did males; they felt happier than males did after success but felt more like a failure than did males after imagining receiving an F on an examination. Some of the gender differences in causal attributions, especially for ability attributions, depended on the gender-type of the subject matter of the examinations. The implications of these findings are discussed.     

Embodied Religious Thought: Gender Categories in Mesoamerica

Soon Huemac found out [that] his daughter was sick.He then asked the women who were taking care of her‘What did she do? [. . .] How did this heat enter my daughter?’And the women who took care of her answered,‘It’s the Tohuenyo, he who’s selling chili:he has put fire in her, he’s made her restless. That’s how it began, that’s how it is that she fell sick’.-Códice MatritenseBody perceptions are embedded both in gender and culture. Mesoamerican sources are particularly revealing of that relationship. Concepts like equilibrium and fluidity are fundamental to grasp perception-constructions of bodies in ancient Mexico. A review of primary sources for the history of ancient Mexico manifests a conception of corporality that could be denominated ‘embodied thought’. Equilibrium, fluidity and gender define the way the body is conceptualized.     

Haptic curvature discrimination at several regions of the hand

Static haptic discrimination of the curvature of convex, concave, or straight 20-cm-long strips was investigated for nine placements on the hand. In one condition, the strips were touched with the palmar side of the hand, and in the other condition, with the dorsal side. The influence of the lengths of the strips, and thus of contact lengths, was also investigated. For all placements, discrimination was poorer in the dorsal than in the palmar condition, owing to poorer cutaneous resolution on the dorsal side of the hand (the kinesthetic stimulation was the same in both conditions). Thus cutaneous stimulation is important. In both experiments, performance appeared to depend primarily on contact length. Moreover, the discrimination thresholds for all different placements and contact lengths followed the same trend. We conclude that in these experiments the effective stimulus for the discrimination of curved strips is the total difference of local surface attitude—that is, the slope difference over the far ends of the stimulus.     

Span of apprehension in hyperactive boys

The spans of apprehension of hyperactive and normal boys were compared with a forced-choice letter-recognition task developed by Estes (1965). This task provides an estimate of the span which is relatively insensitive to either memory or motivational influences. The span size was the same for both groups when visual noise was absent. In the presence of noise, span size for the hyperactive boys decreased. Moreover, as the number of noise letters increased, the reduction in span size observed for the hyperactive boys increased. It is argued that this increasing reduction in span size represents a true deficit in attention.     

A factor analysis of mental abilities and personality traits

The relationship between measures of verbal fluency and certain personality traits is examined by factor techniques. From a matrix of eight factor scores derived from mental tests plus five personality scores, six factors were obtained. An oblique solution lends limited support to the hypothesized relationship between the two domains.This study was supported by a grant from the Research Foundation of the University of Utah.Currently on leave of absence with the National Research Council.     

Individual differences in word recognition latency

Previous studies of the effects of word characteristics on word recognition have used orthogonal combinations of word variables and have failed to consider individual differences. The present study examined word naming (Experiment 1) and lexical decision (Experiment 2) tasks using an unrestricted set of words and a correlational analysis. Individual differences were considered using a measure of the subjects’ knowledge of the English vocabulary. The results of Experiment 1 indicated that log (RT) for word naming is affected by word length, word frequency, and the number of syllables in the word; the results of Experiment 2 confirmed the effects of length and frequency but also showed that log (RT) is a function of the age at which the word is introduced to a child’s reading vocabulary. Subjects with a high vocabulary score were more rapid in Experiment 1 but were slower in Experiment 2, compared to subjects with a low vocabulary score. More importantly, high-vocabulary subjects, in both studies, were less affected by word length than the low-vocabulary subjects. The results suggest that subjects do differ in their reading strategy and that word length and word frequency may affect different stages in the word recognition process.
