Development of mental attention in gifted and mainstream children: the role of mental capacity, inhibition, and speed of processing.

The study examined performance of 6- to 11-year-old children, from gifted and mainstream academic programs, on measures of mental-attentional capacity, cognitive inhibition, and speed of processing. In comparison with mainstream peers, gifted children scored higher on measures of mental-attentional capacity, responded more quickly on speeded tasks of varying complexity, and were better able to resist interference in tasks requiring effortful inhibition. There was no group difference on a task requiring automatic inhibition. Comparisons between older and younger children yielded similar results. Correlations between inhibition tasks suggest that inhibition is multidimensional in nature, and its application may be affected by task demands. Measures of efficiency of inhibition and speed of processing did not explain age or group differences on a complex intellective measure of mental-attentional capacity.

Lack of association of computer use and ability with spontaneous mental visualization.

Relationships between frequency of computer use or ability to use the computer effectively with the tendency to construct and process visual mental images were investigated by administering a computer-use questionnaire and a visualization questionnaire to a sample of 185 Italian and Spanish undergraduates. Analysis did not support associations between either (a) frequent computer use of any kind or (b) high competence in using the computer for various purposes and spontaneous use of imagery.

Becoming an independent Community Mental Health Center: perils of the process.

Over the past 12 years, since the inception of the Community Mental Health Center (CMHC) movement, there has been increasing concern that local communities have more input; in fact, that they actually have the opportunity to operate the mental health programs that they deem necessary for their communities.(1)Under the Amendments to the Community Mental Health Act (P.L.94-63) 1975, CMHCs were given such options as independence or governance. The whole process of governance presents numerous problems as well as opportunities. An overview of the vicissitudes of this process is presented in this paper.

Epileptic psychosis--diagnostic comparison with process schizophrenia.

The mental states of 23 epileptic psychotic patients and 10 patients with process schizophrenia were compared, using the Present State Examination. The epileptics displayed marked heterogeneity of psychiatric diagnoses. Disturbances of affect underlying the psychosis or presenting as manic-depressive psychosis were frequent and independent of the type of epilepsy. Schizophrenic psychosis, classified with psychopathological criteria similar to those used in the non-epileptic schizophrenic group, was significantly associated with temporal lobe epilepsy. Psychoses other than schizophrenia, however, were present in 5 out of 16 patients with temporal lobe epilepsy. These results support a relationship between schizophrenic symptoms and temporal lobe pathology and emphasize the need to use reproducible methods of diagnosis in psychiatric research.

In your right mind: right hemisphere contributions to language processing and production.

The verbal/nonverbal account of left and right hemisphere functionality is the prevailing dichotomy describing the cerebral lateralization of function. Yet the fact that the left hemisphere is the superior language processor does not necessarily imply that the right hemisphere is completely lacking linguistic ability. This paper reviews the growing body of research demonstrating that, far from being nonverbal, the right hemisphere has significant language processing strength. From prosodic and paralinguistic aspects of speech production, reception, and interpretation, to prelexical, lexical and postlexical components of visual word recognition; strong involvement of the right hemisphere is implicated. The evidence reviewed challenges the notion that language is solely a function of the "verbal" left hemisphere, indicating that the right cerebral hemisphere makes significant and meaningful contributions to normal language processing as well.

Motion capture changes to induced motion at higher luminance contrasts, smaller eccentricities, and larger inducer sizes.

In the stimulus configuration for "motion capture" phenomenon, we varied luminance contrast of the center disk (target), eccentricity and stimulus size. The subjects had to judge the direction of perceived target motion. We found that motion capture changed to induced motion (the direction of illusory motion was reversed) at smaller eccentricities and larger stimulus sizes. At intermediate eccentricities, motion capture changed to induced motion with increasing luminance contrast of the target. By using magnitude estimation, we also found that even a luminance-defined target was captured ("homochromatic motion capture") and that a moving target was captured by a stationary inducer ("position capture"). Both motion and position capture effects were commonly observed at lower luminance contrasts of the target, larger eccentricities and smaller sizes. From these results, we propose a model of center-surround antagonistic motion contrast detectors in motion processing.

Different time courses of integrative semantic processing for plural and singular nouns: implications for theories of sentence processing.

The research investigated the time course of integrative semantic processing during sentence processing. Reading time was measured on sentences containing an NP composed of an adjective and a noun whose combined meaning was plausible or anomalous (Experiment 1) or was typical or atypical (Experiment 2). The noun in the NP was either plural or singular. Plural nouns were expected to be more rapidly integrated with a preceding adjective than singular nouns because plural nouns can be ruled out as the first noun in a noun compound more rapidly than singular nouns. The results confirmed this prediction, showing that the effects of semantic plausibility and typicality were observed immediately during the processing of plural nouns, but were observed at a delay following the processing of singular nouns. Implications for theories of sentence processing are discussed.

Sex differences in processing printed advertisements.

The success of using biological sex to divide or segment markets requires a thorough understanding of how men and women process and respond to advertisements and other persuasive communications. Toward this end, this research (N=64; 32 men and 32 women) studied how college-age men and women respond to printed advertisements. There were no differences between the sexes in recall and recognition of claims in advertisements, but men and women generated different types of message relevant thoughts-women generated more category thoughts and men generated more attribute thoughts, suggesting that, while women and men might not differ in the depth of processing, they might use different processing styles.

Accessing situation model information: memory-based processing versus here-and-now accounts.

The focus of the present research was to compare the memory-based processing and here-and-now accounts of situation model updating during reading. The authors conducted two experiments as a follow-up on work by R. A. Zwaan and C. J. Madden (2004), who disputed the conclusions of E. J. O'Brien, M. L. Rizzella, J. E. Albrecht, and J. G. Halleran (1998). The latter researchers found support for the memory-based processing view by showing that readers experienced reading difficulty on a sentence that was consistent with an updated model of the story's protagonist but was inconsistent with initially stated information about the protagonist. In contrast, Zwaan and Madden eliminated what they argued were confounds in the items used by O'Brien et al. and found support for the here-and-now view. In the present article, data from 2 experiments seem to eliminate weaknesses inherent in both previous authors' work. Although the present results are consistent with the here-and-now account, they do not completely discredit the memory-based processing view.

[Speech and thought disorder in frontal syndrome following subarachnoid hemorrhage].

Here is described a case of a patient suffering from cerebral hemorrhage resulting in the perforation of the third cerebral ventricle and massive damage of the frontal lobes in consequence of the rupture of an intracranial aneurysm. After neurosurgical operation the patient's general state improved, but in spite of this he displayed symptoms of the frontal syndrome with many symptoms in the area of abstractional thinking and reflectiveness and a significant reduction of higher emotionality. Very interesting in this case is the neurolinguistic symptomatology. The rehabilitation and pharmacotherapy was very successful. This case is very interesting because it contains many of the symptoms called "frontal syndrome". It is also important to show the role of the frontal lobes in the integral process of mental life and in the role of the left hemisphere in the gnostic and coordinative processes of speech and other higher functions of the central nervous system.

[Everyday psychiatry--a contribution to the hermeneutics of diagnostic and therapeutic clinical practice].

The relations between diagnostic and therapeutic practice and the events of everyday life are investigated in a two-fold regard. The first view is directed towards the signification of "psychiatry" and of the psychiatric view-points in the everyday life of society; the second view is the experience of everyday life inside psychiatric institutions. Under both aspects an interest in the development and the both aspects an interest in the development and the process of mental illness is pursued, which is also an interest in correct diagnostic insight and in promoting therapeutic consequence that positively influences the process.
