Are age-related changes in cognitive function driven by age-related changes in sensory processing?

Although there has been keen interest in the association among measures of sensory function and cognitive function for many years, in general, measures of sensory function have been confined to one or two senses and measures of threshold sensitivity (acuity). In this study, rigorous psychophysical measures of threshold sensitivity, temporal gap detection, temporal order identification, and temporal masking have been obtained, in hearing, vision, and touch. In addition, all subjects completed 15 subtests of the Wechsler Adult Intelligence Scale, 3rd edition (WAIS–III). Data were obtained from 245 adults (18–87 years old) for the WAIS–III and for 40 measures of threshold sensitivity and temporal processing. The focus in this report is on individual differences in performance for the entire data set. Principal-components (PC) factor analysis reduced the 40 psychophysical measures to eight correlated factors, which were reduced further to a single global sensory processing factor. Similarly, PC factor analysis of the 15 WAIS–III scores resulted in three correlated factors that were further reduced to a single global cognitive function factor. Age, global sensory processing, and global cognitive function were all moderately and significantly correlated with one another. However, paired partial correlations, controlling for the third of these three measures, revealed that the moderate correlation between age and global cognitive function went to zero when global sensory processing was controlled for; the other two partial correlations remained intact. Structural models confirmed this result. These analyses suggest that the long-standing observation of age-related changes in cognitive function may be mediated by age-related changes in global sensory processing.     

Collaborative false recall in the DRM procedure: Effects of group size and group pressure

Basden, Basden, Thomas, and Souphasith (1998) demonstrated that false recall in collaborative trios is enhanced when group members feel under pressure to output items. In the present study, individuals, pairs, trios, and quartets were presented with lists of words drawn from the Deese-Roediger-McDermott paradigm. Memory was tested under high or low group pressure conditions. It was found that false recall increased in proportion to group size regardless of group pressure, but that groups experiencing the most pressure to output items made a greater number of errors. Furthermore, on a surprise later individual recall test, participants who experienced the most pressure during collaboration retained an equivalent level of critical lures. Collectively these findings demonstrate that group pressure can increase collaborative false recall, and that these false memories can be retained beyond group testing.     

Development of a Measure of Stereotypical Attitudes towards Older Workers

Prolonging the working life of older adults has been suggested by various researchers and policymakers as a strategy to alleviate challenges posed by the inevitable ageing of the population. It is thus important to have measures with which to assess and monitor factors relevant to older adults' employment. Research indicates that negative attitudes towards older workers are at the heart of employment discrimination; hence, the current research developed and assessed a new measure of attitudes towards older workers. A questionnaire asking about older workers was prepared in three versions (male, female, and gender neutral). Each version of the Attitudes towards Older Workers Scale (AOWS) was pilot tested, refined, and field tested with random samples totalling 246 hiring decision‐makers and 219 undergraduate students. Internal consistency ranged between .89 and .95 across the samples and questionnaire versions. Test–retest reliability correlations for male, female, and gender‐neutral versions were .83, .78, and .90, respectively. The AOWS will be a valuable tool for research, development of interventions, and for informing policy formulation in the areas of ageing, retirement, and employment.     

Perceived Government Actions and Attitudes Toward the Needy

Potential negative effects of welfare agencies on attitudes toward the needy were examined in the context of a communications study. After listening to a bogus newscast describing one of four levels of government involvement and one of two levels of need, 120 undergraduate women indicated their perceptions of the degree of need and their perceptions of the extent of citizens’ responsibility for helping to meet this need. Results showed that government failure to provide proposed assistance resulted in Ss perceiving the need to be less severe. Ss’ perceptions of citizens’ responsibility were lowered when the government either withdrew existing support or failed to provide proposed aid. Government involvement, existing or withdrawn, attenuated the effect of the manipulation of need.     

McSexy: Exotic Dancing and Institutional Power

A growing body of research is exploring the relationship between power and women's sexuality in occupations that involve the vending of sex or the sale of sexuality. Previous research has examined power in the field of exotic dancing on the individual level and at the interactional/organizational level. This research examines dancer power at the institutional level. Data were gleaned from interviews with 133 female dancers in several cities and level of clubs.     

Macro and Micro Views of Erotic Tourism

This article examines the deviant phenomenon of erotic tourism from both macro and micro level perspectives. The current study deals exclusively with erotic tourism involving the provision of a sexual experience for male tourists either as voyeurs or participants in sex acts with females. The origins of the industry are discussed as well as its implications for sexual deviance.
