Perceptual and motor attribute ratings for 559 object concepts

To understand how and when object knowledge influences the neural underpinnings of language comprehension and linguistic behavior, it is critical to determine the specific kinds of knowledge that people have. To extend the normative data currently available, we report a relatively more comprehensive set of object attribute rating norms for 559 concrete object nouns, each rated on seven attributes corresponding to sensory and motor modalities??color, motion, sound, smell, taste, graspability, and pain??in addition to familiarity (376 raters, M = 23 raters per item). The mean ratings were subjected to principal-components analysis, revealing two primary dimensions plausibly interpreted as relating to survival. We demonstrate the utility of these ratings in accounting for lexical and semantic decision latencies. These ratings should prove useful for the design and interpretation of experimental tests of conceptual and perceptual object processing.     

Human papillomavirus vaccination intentions and uptake in college women

Objective: Using the health belief model (HBM) and theory of planned behavior (TPB) as theoretical frameworks, the objectives of this study were: (a) to identify correlates of human papillomavirus (HPV) vaccination intentions and (b) to explore differences between correlates of HPV vaccination intentions and uptake. Methods: Undergraduate women (N = 447) who did not intend to receive (n = 223), intended to receive (n = 102), or had received (n = 122) the HPV vaccine were surveyed. Logistic regressions were conducted to examine the correlates of vaccination intentions and uptake. Results: Negative health consequences of the vaccine, physician's recommendation, positive attitudes toward the vaccine, and subjective norms were significant correlates of vaccination intentions. When comparing correlates of vaccination intentions to correlates of vaccination uptake, physician's recommendation, subjective norms, and perceived susceptibility to HPV were unique correlates of uptake. Conclusion: Differences between correlates of vaccination intentions and uptake suggest that social influences of liked and trusted individuals may make an important and unique contribution in motivating young women to receive the HPV vaccine beyond other variables from the HBM and TPB. Future utilization of longitudinal designs is needed to understand which factors may cause individuals to decide to receive the HPV vaccine.

Quantitative Media Literacy: Individual Differences in Dealing with Numbers in the News

A test of arithmetic aptitude was developed and validated. The consequences of individual differences in this aspect of quantitative literacy were then determined for attention to, and dependent recall of, numeric quantities embedded in printed news reports. It was found that persons of high arithmetic aptitude recalled frequencies and ratios more correctly, both in precise and approximate terms, than did persons of low arithmetic aptitude. This effect was consistent across gender of respondent. It was also consistent across commonly employed presentational formats of numeric quantities. The inferior processing of numeric quantities by persons of low quantitative literacy, especially the dependent estimation of risk and benefit likelihoods, is considered in terms of theories that project these persons' greater reliance on intuitive assessments of the incidence of occurrences.     

Psychologists' attitudes toward aids

Abstract

Practicing psychologists in all areas of the country will see an increasing number of persons at risk for AIDS, or with AIDS-related illnesses. Previous research has shown that AIDS elicits negative reactions from the general public and from certain health care professionals. In the current study, a national sample of randomly selected practicing psychologists completed attitude measures after reading vignettes that described a male patient with either AIDS or leukemia who was either homosexual or heterosexual. Respondents evaluated the AIDS patient more negatively and reported less willingness to interact with him in a professional role or in casual social situations. It is important to develop training and continuing education programs to prepare psychologists to deal with persons affected by AIDS.     

Gamma- and theta-band synchronization during semantic priming reflect local and long-range lexical–semantic networks

Anterior and posterior brain areas are involved in the storage and retrieval of semantic representations, but it is not known how these areas dynamically interact during semantic processing. We hypothesized that long-range theta-band coherence would reflect coupling of these areas and examined the oscillatory dynamics of lexical–semantic processing using a semantic priming paradigm with a delayed letter-search task while recording subjects’ EEG. Time–frequency analysis revealed facilitation of semantic processing for Related compared to Unrelated conditions, which resulted in a reduced N400 and reduced gamma power from 150 to 450 ms. Moreover, we observed greater anterior–posterior theta coherence for Unrelated compared to Related conditions over the time windows 150–425 ms and 600–900 ms. We suggest that while gamma power reflects activation of local functional networks supporting semantic representations, theta coherence indicates dynamic coupling of anterior and posterior areas for retrieval and post-retrieval processing and possibly an interaction between semantic relatedness and working memory.
