Correcting Big Five Personality Measurements for Acquiescence: An 18‐Country Cross‐Cultural Study

For groups of persons with low or medium levels of education, Big Five personality scales typically yield scores that poorly replicate the idealized Big Five factor pattern. On the basis of representative samples of German adults, Rammstedt et al. have demonstrated that correcting each person's score for acquiescence eliminates this problem. In the present 18‐country study using large samples representative of each country's adult population, we found that, in all cases, correcting for acquiescence did indeed improve the congruence of factor loadings with an idealized Big Five pattern. However, although this correction led to acceptably high correspondence levels in all countries classified as individualistic, this was not always true for non‐individualistic countries. Possible reasons for this finding are discussed. Copyright © 2012 John Wiley & Sons, Ltd.     

Different Effects of Dual Task Demands on the Speech of Young and Older Adults

Abstract

Young and older adults provided language samples in response to elicitation questions while concurrently performing 3 different tasks. The language samples were scored on three dimensions: fluency, grammatical complexity, and content. Previous research has shown that older adults use a restricted speech register that is grammatically less complex than young adults’ and has suggested that this restricted speech register is buffered from the costs of dual task demands. This hypothesis was tested by comparing language samples collected during a baseline condition with those produced while the participants were performing the concurrent tasks. The results indicate that young and older adults adopt different strategies when confronted with dual task demands. Young adults shift to a restricted speech register when confronted with dual task demands. Older adults, who were already using a restricted speech register, became less fluent although the grammatical complexity and informational content of their speech was preserved. Hence, some but not all aspects of older adults’ speech are buffered from dual task demands.     

Tracking talking: dual task costs of planning and producing speech for young versus older adults

A digital pursuit rotor was used to monitor speech planning and production costs by time-locking tracking performance to the auditory wave form produced as young and older adults were describing someone they admire. The speech sample and time-locked tracking record were segmented at utterance boundaries and multilevel modeling was used to determine how utterance-level predictors such as utterance duration or sentence grammatical complexity and person-level predictors such as speaker age or working memory capacity predicted tracking performance. Three models evaluated the costs of speech planning, the costs of speech production, and the costs of speech output monitoring. The results suggest that planning and producing propositionally dense utterances is more costly for older adults and that older adults experience increased costs as a result of having produced a long, informative, or rapid utterance.     

Automatic measurement of propositional idea density from part-of-speech tagging

The Computerized Propositional Idea Density Rater (CPIDR, pronounced "spider") is a computer program that determines the propositional idea density (P-density) of an English text automatically on the basis of part-of-speech tags. The key idea is that propositions correspond roughly to verbs, adjectives, adverbs, prepositions, and conjunctions. After tagging the parts of speech using MontyLingua (Liu, 2004), CPIDR applies numerous rules to adjust the count, such as combining auxiliary verbs with the main verb. A "speech mode" is provided in which CPIDR rejects repetitions and a wider range of fillers. CPIDR is a user-friendly Windows .NET application distributed as open-source freeware under GPL. Tested against human raters, it agrees with the consensus of two human raters better than the team of five raters agree with each other [r(80) = .97 vs. r(10) = .82, respectively].     

Eye movements of young and older adults during reading

The eye movements of young and older adults were tracked as they read sentences varying in syntactic complexity. In Experiment 1, cleft object and object relative clause sentences were more difficult to process than cleft subject and subject relative clause sentences; however, older adults made many more regressions, resulting in increased regression path fixation times and total fixation times, than young adults while processing cleft object and object relative clause sentences. In Experiment 2, older adults experienced more difficulty than young adults while reading cleft and relative clause sentences with temporary syntactic ambiguities created by deleting the that complementizers. Regression analyses indicated that readers with smaller working memories need more regressions and longer fixation times to process cleft object and object relative clause sentences. These results suggest that age-associated declines in working memory do affect syntactic processing.     

Black and white adolescent males' perceptions of ideal body size

A stratified random sample of 496 white (n =337) and black (n =159) adolescent males participated in a survey of ideal body size beliefs. Responses to the questionnaire and a series of nine female and male body size drawings were analyzed using the General Linear Model Analysis of Variance and Categorical Modeling. Using SES and race as independent variables and BMI (kg/m ²)as a covariate, black males were found to prefer a significantly heavier ideal female body size than whites (p <.0001) and also perceived that their parents, female friends, and male friends would select as ideal a significantly heavier female body size than white subjects. Black subjects were 1.9 times (O.R. = 1.88, 95% C.I. = 1.44, 2.47) more likely to select a larger ideal female hip/buttocks size and 1.7 times (O.R. = 1.72, 95% C.I. = 1.25, 2.37) more likely to choose a larger ideal female thigh size than white subjects. Our findings seem to point toward a greater approval and social acceptance of a larger body size for black females by black males.

When to speak like a lady

The existence of sexually biased stereotypes about the polite speech of men and women was documented in a series of three studies. In Study I, masculine, feminine, and neutral activities were identified. In Study II, the perceived politeness of five different forms of requests was determined. In the final study, men and women were asked to judge the appropriateness of requests by men and women speakers to addressees of either sex. The requests differed in politeness, and requested either masculine, feminine, or neutral actions. These ratings revealed that women are expected to speak more politely than men, regardless of the sex of the addressee or the nature of the requested action. However, men are expected to use different forms for requests for masculine, feminine, and neutral actions and to use different forms of requests for men and women addressees.     

Telling stories: The structure of adults' narratives

Abstract

Adults' narratives were analysed to study life-span changes in their structure. The narratives were collected from a group of adults in their 60s, 70s, and 80s. Four separate analyses were performed on the narratives' (1) hierarchical structure, (2) syntactic structure, (3) propositional content, and (4) cohesion. Age-group differences were obtained for the measures of hierarchical structure, syntactic structure, and cohesion. Further analyses revealed that the structural complexity of the narratives influenced their syntactic structure and cohesion. Interactions between the effects of age group and structural complexity suggest that elderly adults minimise the syntactic complexity of their narratives, reducing their cohesion, when producing structurally complex narratives. Finally, ratings of the quality of the narratives were strongly correlated with their structural complexity, suggesting that telling a “good” story involves constructing complex plots.
