The Short-Term Memory of Profoundly Deaf People for Words,Signs, and Abstract Spatial Stimuli

The short-term memory (STM) of 25 deaf and 20 hearing adults fluent in Australian Sign Language (Auslan) was tested using both free- and serial-recall versions of three tasks. On two tasks, where stimuli were presented as either written words or Auslan signs, hearing subjects performed significantly better than deaf subjects. This difference was attributed to the facility of the hearing subjects in translating these two classes of language-based stimuli into phonological codes, which have a preferred status in STM. On the third, language-free task, which was an adaptation of the Corsi Blocks test, the deaf and hearing subjects performed at comparable levels, indicating that differences in their STM became evident only with the introduction of language-based factors. Analyses restricted to the deaf subjects showed that performances on the language-based STM tasks correlated positively with scores on a reading comprehension test. Also, deaf subjects who reported an oral education outperformed their counterparts, who reported a total communication (oral plus signed English) education on the language-based STM tasks. Thus, for this diverse adult deaf sample, proficiency in STM for language-based material, skill in reading, and report of an oral rather than total communication education appear to covary.     

A cognitive model in which representations are images

Interpretations of images of the brain are starting to reveal the conceptual tasks in which the person was engaged at the time of imaging. Existing mathematical models can explain the patterns of activity observed in such images in terms of the coherent activity of large populations of neurons, but not in terms of cognition. This paper is an early investigation into how such patterns might provide the internal representations for a cognitive system. Probes, working memories and memories are all represented as images. The accompanying process model describes how attention is set according to the contents of working memory, how attention determines what parts of the probe are memorised, how memories are activated according to similarity to the probe in areas in attention, and how working memory is managed. The model is demonstrated on re-creations of classic simulations of recognition memory and categorisation.     

First Annual Diversity Challenge: “How to Survive Teaching Courses on Race and Culture”

The authors discuss the highlights of the 1st annual Diversity Challenge held October 11–12, 2001, at Boston College, Boston, MA. The Challenge's general focus was preparing educators to cope with the resistances encountered when they teach about race and ethnic culture. This introduction (a) provides an overview of the proceedings, (b) summarizes themes of presentations and articles selected, and (c) offers recommendations for subsequent events. Los autores analizan el primer Reto de Diversidad, que tuvo lugar del 11 al 12 de octubre, 2001, en Boston College, Boston, Massachusetts. El próposito del reto fue preparar a los profesores para que puedan enfrentar las dificultades que resultan de enseñar los temas de la raza y la cultura étnica. Esta introducción (a) da un breve resumen de los procedimientos, (b) resume los temas de las presentaciones y los ensayos seleccionados, y, (c) sugiere recommendaciones para eventos posteriores.     

Mother–Child Agreement on Reports of Internalizing Symptoms Among Children Referred for Evaluation of ADHD

The effects of maternal (bias), child (age, severity of behavior problems), and measurement characteristics (similarity of parent and child measures; types of internalizing symptoms) on mother–child agreement on reports of children's internalizing symptoms were examined for 65 children referred for evaluation of ADHD. Agreement was low and did not improve when parents and children completed parallel measures. Mothers and children were more likely to agree on severity of internalizing symptoms rated as behavioral than those rated as ideational. The majority of discordant reports were of the type that mothers, but not children, reported clinically elevated symptoms. This type of discordance appeared to be a function of maternal negative bias rather than underreporting of symptoms by children.     

A Quantum Biomechanical Basis for Near-Death Life Reviews

Near-death life reviews pose a challenge to current memory research in terms of the sheer amount of instantaneous and empathetic information recall. Advances in quantum physics, biomechanics, holographic information theory, and consciousness studies support for the first time a fully realizable quantum biomechanical basis for near-death life reviews. We introduce the unifying paradigm of the quantum hologram as a non-local carrier of information. We further investigate the interrelated phenomena of non-local communications, and the electromagnetic zero-point field. Recent confirmation of the zero-point field lends credibility to vast memory storage capabilities outside the physical body. Microtubules are considered to be key components in non-local, quantum processes critical to human consciousness. Discovery of the liquid crystalline nature of the human body provides further support for our model. Microtubules, deoxyribonucleic acid (DNA), and the entire brain are described as communicating non-locally with virtually unlimited memory storage capacity.     

Improving judgement with prepaid expert advice

Decision makers (“Judges”) often make decisions after obtaining advice from an Advisor. The two parties often share a psychological “contract” about what each contributes in expertise to the decision and receives in monetary outcomes from it. In a laboratory experiment, we varied Advisor Experitise and the opportunity for monetary rewards. As expected, these manipulations influenced advice quality, advice taking, and Judge post‐advice decision quality. The main contribution of the study, however, was the manipulation of the timing of monetary rewards (before or after the advising interaction). We found, as predicted, that committing money for expert—but not novice—advice increases Judges' use of advice and their subsequent estimation accuracy. Implications for advice giving and taking are discussed. Copyright © 2004 John Wiley & Sons, Ltd.     

Psychosocial Factors Associated With Stage of Change for Contraceptive Use Among Women at Increased Risk for HIV and STDs

This study assessed the psychosocial factors associated with contraceptive use among inner-city women at risk for HIV/STDs by using the transtheoretical model of behavior change. The five-city study group of women aged 15 to 34 years was recruited from neighborhoods, social service agencies and shelters ( n = 998). We measured stages of change for contraceptive use and assessed theoretically proposed factors associated with being at a higher stage. Variables such as perceived advantages of contraceptive use and normative support for use were very important at early stages, but less important in later stages. However, self-efficacy was important in both early (OR =1.5) and later (OR = 1.6) stages, suggesting that women's confidence in their ability to initiate and sustain contraceptive use is crucial.
