Reduced felt arm sensation effects on visual adaptation

Proprioception is often considered to be critically involved in producing adaptation to a prism-induced visual displacement. The present study focused on reduction of proprioceptive feedback during prism exposure by means of hypnotically induced anesthesia in the adapting arm. In addition, intermanual transfer was considered. Results showed adaptation occurring in situations where S could feel arm sensations while viewing arm movement during a prism exposure. However, if the adapting arm was hypnotically anesthetized while still remaining mobile, adaptation did not occur. No intermanual transfer was found between the adapted arm and the unadapted arm.     

Disorders of lexical selection.

Errors in lexical processing are commonplace in language pathologies resulting from brain injury or disease. This discussion considers some of the major recent developments in the interpretation of such errors. The focus is on behavioral systems, rather than neuroanatomical or neurophysiological issues. The objective is to comment on some plausible mutual implications of generally attested pathologies and normal models of lexical retrieval for production, particularly with respect to the roles of semantic and syntactic categories.     

Constructive Development and Career Transition: Implications for Counseling

The ability to effectively manage career transition may be related to an individual's meaning-making framework, or constructive development. The implications of constructive developmental theory for career choice and implementation are explored. The interplay between career transition and developmental transformation is examined, and counseling strategies for assisting such transformation are proposed. Case illustrations are offered.     

Estimates of test size for several test procedures based on conventional variance ratios in the repeated measures design

Estimates of test size (probability of Type I error) were obtained for several specific repeated measures designs. Estimates were presented for configurations where the underlying covariance matrices exhibited varying degrees of heterogeneity. Conventional variance ratios were employed as basic statistics in order to produce estimates of size for a conventional test, an -adjusted test, and -adjusted test and a conservative test. Indices for empirical distributions of two estimators of , a measure of covariance heterogeneity, were also provided.     

Mending the Broken Circle: Treatment of Substance Dependence Among Native Americans

Issues surrounding substance dependence of Native Americans are examined through the cultural concept of the Broken Circle. Traditional cultural views of wellness and healing are described using the traditions of Indian Medicine, the value of the Circle, and what it means to live in harmony and balance. Underlying factors in substance dependence of Native Americans are presented along with practical counseling recommendations and implications for treatment through both contemporary and traditional Native healing methods.     

Working memory representations persist in the face of unexpected task alterations

It is well known that information can be held in memory while performing other tasks concurrently, such as remembering a color or number during a separate visual search task. However, it is not clear what happens to stored information in the face of unexpected tasks, such as the surprise questions that are often used in experiments related to inattentional and change blindness. Does the unpredicted shift in task context cause memory representations to be cleared in anticipation of new information? To answer this question, we ran two experiments where the task unexpectedly switched partway through the experiment with a surprise question. Half of the participants were asked to report the same attribute (Exp. 1?=?Identity, Exp. 2?=?Color) of a target stimulus in both presurprise and postsurprise trials, while for the other half, the reported attribute switched from identity to color (Exp. 1) or vice versa (Exp. 2). Importantly, all participants had to read an unexpected set of instructions and respond differently on the surprise trial. Accuracy on the surprise trial was higher for the same-attribute groups than the different-attribute groups. Furthermore, there was no difference in reaction time on the surprise trial between the two groups. These results suggest that information participants expected to report can survive an encounter with an unexpected task. The implication is that failures to report information on a surprise trial in many experiments reflect genuine differences in memory encoding, rather than forgetting or overwriting induced by the surprise question.     

A Difference of Some Consequence Between Conventions and Rules

Lewis’s view of the way conventions are passed on may have some especially interesting consequences for the study of language. I’ll start by briefly discussing agreements and disagreements that I have with Lewis’s general views on conventions and then turn to how linguistic conventions spread. I’ll compare views of main stream generative linguistics, in particular, Chomsky’s views on how syntactic forms are passed on, with the sort of view of language acquisition and language change advocated by usage-based or construction grammars, which seem to fit better with Lewis’s ideas. Then I will illustrate the interest of Lewis’s perspective on the dissemination of conventions with a variety of linguistic examples.
