Medical problems,maladaptive behaviors,and the developmentally disabled

Research has shown that aberrant behaviors of people with developmental disabilities have multiple determinants; of these, medical problems and their potential relations to aberrant behaviors, have been, for the most part, not studied. This retrospective study examined the relations of 26 acute medical treatements to the aberrant behaviors of 10 elderly people with developmental disabilities. Results showed that 73.1% of the aberrant behaviors decreased in frequency after medical treatments. The study suggests the importance of acute medical problems and treatments as possible factors in the occurrence of aberrant behaviors in this population.     

Variation of the Subjective Vertical on the parallel swing at different body positions

Summary Subjects on a horizontally moving parallel swing perceive a change of the position of the body and of the Subjective Vertical (SV). The magnitude of the SV-change was recorded at different body-positions on the swing. The SV-change was smaller when the vertex-base head-axis was oriented parallel or close to parallel to swing movement than when the vertex-base head axis was oriented perpendicular to this movement. Perpendicular orientation implies either head vertex-up or head vertex-down. The results are discussed with respect to other findings on the various sensory input systems.

Zusammenfassung Versuchspersonen auf einer horizontal schwingenden Parallel-Schaukel nehmen eine Änderung der Lage des eigenen Körpers und der Stellung der Subjektiven Vertikalen (SV) wahr. Die Größe der im Schwingrhythmus wechselnden SV-Änderung wurde bei verschiedenen Körperstellungen auf der Schaukel untersucht. Sie war kleiner, wenn die Scheitel-Basis-Achse des Kopfes in oder nahe der Schwingungsrichtung und größer, wenn sie senkrecht oder nahezu senkrecht dazu stand; die senkrechte Stellung konnte entweder Scheitel-aufwärts oder Scheitel-abwärts sein. Die Ergebnisse werden im Zusammenhang mit anderen Befunden über die beteiligten sensorischen Systeme diskutiert.

     

Lexical representation of fact and opinion

This research investigated the lexical properties underlying comprehension that a word represents fact or opinion. In Experiment 1 subjects reliably identified words as either fact or opinion. Bivariate correlations and multiple regression showed that fact/opinion judgments were predicted primarily by ratings of the ease of verifiability of a word's referent and secondarily by the word's literalness, but not by several other lexical attributes: abstractness-concreteness, vagueness-preciseness, and evaluation. Experiment 2 extended the results of the first experiment to an implicit fact/opinion judgment, i.e., the identification of headlines as originating from a newspaper's front page (presumably based primarily upon fact) or from the editorial page (presumably based upon opinion). The headline judgments, also made reliably by subjects, were predicted by the same variables found significant in the first experiment, i.e., by verifiability and literalness, but not by the other lexical properties. Thus, the results of both experiments indicate that the identification of a word as representing fact or opinion is rooted in a word's verifiability and literalness.

Masked singleton effects

In the present study, we tested whether visual singletons remaining outside awareness are processed. Singletons differ by at least one feature from their more homogeneous neighbors. Here, we used backward masking to prevent awareness of shape singleton primes (Experiments 1-4) or color singleton primes (Experiment 5). Masked singleton primes nonetheless produced a congruence effect: Congruent singletons indicating the location of subsequent visible targets facilitated responses, in comparison with incongruent singletons at positions away from the targets. This congruence effect was found with singletons defined by feature presence or feature absence. It was at least partly due to attentional capture by singletons remaining outside of the participants' awareness. Results are discussed in light of theories pertaining to singleton effects and masked-priming effects.     

Temporal order judgment criteria are affected by synchrony judgment sensitivity

Synchrony perception for audio-visual stimulus pairs is typically studied by using temporal order judgment (TOJ) or synchrony judgment (SJ) tasks. Research has shown that estimates of the point of subjective simultaneity (PSS) obtained using these two methods do not necessarily correspond. Here, we investigate the hypothesis that the PSS estimate obtained in a TOJ task is shifted in the direction of the most sensitive part of the synchrony judgment curve, as obtained in an SJ task. The results confirm that criterion shifts in the TOJ task move the PSS toward regions of the audio-visual temporal interval continuum where discriminations are most sensitive.     

Development of a Brief Cognitive Screen for Mild Cognitive Impairment and Neurocognitive Disorder

Abstract

The purpose of this study was to develop and evaluate a brief cognitive screen for possible Mild Cognitive Impairment (MCI) and other neurocognitive impairment in a sample of general medical patients. Two hundred community-dwelling general medical patients aged 65 or older participated in this study. Age and education corrected scores from the Rey Auditory Verbal Learning Test and Mattis Dementia Rating Scale were used to classify participants into three groups: MCI, neurocognitive disorder, cognitively intact. Groups were then compared on an independent set of measures: the Consortium to Establish a Registry for Alzheimer’s Disease (CERAD) neuropsychological battery, Mini-Mental State Examination, and Clock Drawing Test. The MCI group constituted 9% of the sample, while 10.5% of the sample was classified into the neurocognitive disorder group. The CERAD Verbal Category Fluency and CERAD Word List Memory Test Delayed Recall measures were individually and collectively the most effective in differentiating cognitively intact elders from persons in both the MCI and neurocognitive disorder groups. We conclude that these two brief measures appear to be effective for detecting possible MCI or neurocognitive disorder, thereby facilitating identification of candidates who would benefit from more detailed neuropsychological assessment.
