Do tests facilitate decision‐making performance on a transfer task?

Testing can improve later recall of information. However, much less is known about the potential use of testing in promoting the transfer of learning. In this study, we investigated whether testing improves decision‐making performance on a transfer task in a sample of 98 university students using a between‐subjects design. After studying several statements about a fictional disease under different learning conditions (restudy, free recall, and multiple‐choice), participants were asked to recall this information and subsequently make medical decisions concerning the fictional disease (i.e., the transfer task). The present study found no advantage of testing conditions over restudy condition on the 30‐min delayed memory task. However, participants in the active retrieval practice (i.e., free recall) group performed significantly better on the transfer task over those in both restudy and multiple‐choice groups. These results suggest free‐recall tests promote the transfer of learning.     

Infants' ability to use luminance information to individuate objects

Recent research indicates that infants first use form and then surface features as the basis for individuating objects. However, very little is known about the underlying basis for infants' differential sensitivity to form than surface features. The present research assessed infants' sensitivity to luminance differences. Like other surface properties, luminance information typically reveals little about an object. Unlike other surface properties (e.g. pattern, color), the visual system can detect luminance differences at birth. The outcome of two experiments indicated that 11.5-month-olds, but not 7.5-month-olds, used luminance differences to individuate objects. These results suggest that it is not the age at which infants can detect a feature, but the nature of the information carried by the feature, that determines infants' capacity to individuate objects.     

Context-dependent Abduction and Relevance

Based on the premise that what is relevant, consistent, or true may change from context to context, a formal framework of relevance and context is proposed in which

Seriously bored: Schopenhauer on solitary confinement

ABSTRACT

Primary textual evidence confirms that Schopenhauer was aware of the widespread adoption of solitary confinement in the American penitentiary system, and some of its harmful effects. He understands its harmfulness in terms of boredom, a phenomenon which he is known to have given extensive thought and analysis. In this paper I interpret Schopenhauer’s account of boredom and its relation to solitary confinement. I defend Schopenhauer against the objection that cases of confinement only serve to illustrate the general inadequacy of his explanation of boredom in terms of a lack of things to will. This defence arrives at the conclusion that, on the contrary, someone might well suffer from a lack of things to will as a direct result of being confined; and that boredom understood as the deprivation of willing, a phenomenon I suggest may be called conative deprivation, makes an illuminating contribution to our theoretical understanding of the harmfulness of solitary confinement.     

Personality and engagement at work: the mediating role of psychological meaningfulness

In this study, we examined the associations of personality traits of the Big Five model with work engagement, and tested a theoretical model in which these associations are mediated by the positive state of psychological meaningfulness (perceptions that work is valuable and meaningful). In a sample of 238 UK working adults, we found that the personality facets assertiveness and industriousness were the strongest predictors of work engagement, and that both exhibited direct and indirect effects, mediated by psychological meaningfulness. Neuroticism demonstrated a marginal indirect association with engagement, again mediated by psychological meaningfulness. Our findings offered good support for our model, explaining a pathway from personality traits to engagement. Practical implications for management are discussed.     

Thoughts Associated with Unprotected Anal Intercourse Among Men at High Risk in San Francisco 1997-1999

Men who had high-risk sex with men in the previous year ( N = 124) were asked to recall their thought processes at the time they last had unprotected anal sex with a man who was HIV-positive or of unknown serostatus. Self-justifications for non-condom use were examined individually and in internally validated scales. The most common single self-justification was I want to have unprotected sex because it feels good , endorsed by 76%. Other common thoughts included the notion that it is only human to slip up occasionally (59%) and the resolution to withdraw before ejaculation (59%). For scaled items, the most strongly endorsed themes were: (1) that condoms reduce sexual pleasure (any of 6 items endorsed at least slightly by 90%); (2) fatalism or leaving it to chance (11 items, 81%); and (3) loss of control (9 items, 77%). The thoughts and themes identified may be useful in planning individual and community prevention messages.     

The 328 cm−1 infrared absorption band in type Ia diamonds

Abstract

A defect-induced peak at 328 cm^?1 in the infrared absorption spectrum of type Ia diamonds is confirmed to belong with the other absorptions (in particular, the B′ localised mode near 1370 cm^?1 and the D component of the lattice vibrations) which are associated with the {100} platelets found in these crystals. It is suggested that this absorption and other weaker absorptions found in its vicinity may be due to the bending vibrations of atomic bonds in the platelets.     

Does prospective memory influence quality of life in community-dwelling older adults?

Older adults commonly experience declines in prospective memory, which describes one’s ability to “remember to remember,” and can adversely affect instrumental activities of daily living and healthcare compliance. However, the extent to which prospective memory failures may influence quality of life in typically aging older adults is not well understood. One-hundred and four community-dwelling older Australians (aged 50 to 82 years) were administered a comprehensive, neuropsychological battery that included the Memory for Intentions Screening Test (MIST), Prospective and Retrospective Memory Questionnaire (PRMQ), Instrumental Activities of Daily Living Questionnaire (IADLQ), and World Health Organization Quality of Life-8 (WHOQOL-8). Multiple regressions controlling for negative affect, medical comorbidities, and other neurocognitive functions revealed an interaction between prospective memory and instrumental activities of daily living in the concurrent prediction of quality of life. Among the 39 older adults who reported multiple problems on the IADLQ, lower performance-based prospective memory (MIST) and higher self-reported prospective memory failures in daily life (PRMQ) were significantly associated with lower quality of life (WHOQOL-8). Conversely, no significant associations were observed between prospective memory and quality of life in the 65 participants without IADL problems. Prospective memory difficulties adversely impact quality of life in community-dwelling older adults who experience problems independently managing their instrumental activities of daily living. These findings extend prior literature showing that prospective memory plays a unique role in the real-world outcomes of older adults and clinical populations and highlight the need to develop effective strategies to enhance prospective memory functioning in these vulnerable groups.     

Using habit reversal to treat chronic vocal tic disorder in children

In the present study, a nonconcurrent multiple baseline design was used to evaluate the effectiveness of simplified habit reversal in three children diagnosed with chronic vocal tic disorder. In two children, vocal tics were substantially reduced. In a third child, tics were not reduced, and the addition of a supplemental contingency management program was ineffective. Despite these mixed results, the treatment was viewed as acceptable to the children's parents in all cases as measured by a standard index of treatment acceptability. Implications of these findings are discussed. Copyright © 2002 John Wiley & Sons, Ltd.
