Preschoolers' and adults' attributions of who causes interpersonal events

Adults and 4‐year‐olds explained who caused prosocial or antisocial interactions between two characters who differed in two dimensions that underlie interpersonal traits. Participants saw pictures depicting every pairwise combination of four characters (good/powerful, good/weak, bad/powerful or bad/weak) as initiators or recipients of six actions. Both children and adults made causal attributions to ‘good’ characters for prosocial behaviours and to ‘bad’ characters for antisocial behaviours. Potency influenced the frequency of attributions. Adults and children differed in the justifications of their attributions and in their reconciliations of contradictory information, e.g. a positive character initiating an antisocial act. Explanations of social events are based on characteristics of both interactants in combination with whether the event is prosocial or antisocial. The findings thus extend work on children's ‘theory‐of‐mind’ to the realm of interpersonal interactions, where beliefs, desires or dispositions of either of two characters can cause an event.

Neuropsychological Performance in Gulf War Era Veterans: Neuropsychological Symptom Reporting

Relationships between broad-based health symptoms and neuropsychological performance have been investigated previously in Gulf War (GW) veterans. However, very little has been done to assess relationships between severity of neuropsychological symptom complaints and performance on objective neuropsychological tests. In this study, relationships between level of self-reported neuropsychological symptom severity and objective neuropsychological performance measures were investigated. Participants included 240 veterans from three GW-era cohorts: GW-deployed veterans recruited from Ft. Devens, MA, (n = 142) and from New Orleans, LA (n = 51), and veterans deployed to Germany from a Maine National Guard unit (n = 47). Findings suggest that level of subjective neuropsychological complaints was associated primarily with mood symptoms in GW-era veterans. Among GW-deployed troops, high neuropsychological symptom reporters endorsed more tension, fatigue, and confusion and less vigor than those reporting fewer cognitive complaints. Current findings emphasize the importance of independent assessment of subjective symptoms and objective neuropsychological performance.

Vacuuming with my mouth?: Children's ability to comprehend novel extensions of familiar verbs

Can 6- and 8-year-olds (and adults) comprehend common instrument verbs when extended to novel situations? Participants heard eight unusual extensions of common verbs and were asked to paraphrase the verbs’ meanings. Half of the verbs used were specified instrument verbs that include the name of the instrument used to perform the action (e.g., a vacuum is used to vacuum); the other half were open instrument verbs (e.g., write) whose function can be performed with a range of objects. Results suggest that children's ability to interpret verb extensions increases with age, that open instrument verb extensions were more difficult to comprehend than specified instrument verb extensions and that performance on verb extension correlates with scores on a standardized test of language acquisition. Verb knowledge continues to develop well beyond the preschool years.     

Haptic roughness perception of linear gratings via bare finger or rigid probe

The magnitude of perceived roughness was haptically estimated as subjects freely explored linear gratings with either the bare finger or a rigid stylus-shaped probe. A considerably expanded range of ridge and groove width was investigated, relative to the extant literature. The four experiments collectively indicate that, for both finger and probe-end effectors, the variance in the estimates of perceived roughness was predominantly predicted by a single parameter: groove width. The functions relating perceived roughness to groove width increased over a narrow band relative to the full range of values, then flattened. These data have archival values for models of roughness perception involving both direct and indirect touch.     

Simone de Beauvoir and the Graying of American Feminism

Simone de Beauvoir's study on age and aging can be read as an example of feminist scholarship presenting the contradictions and the ambivalence inherent in any topic dealing with women and society. Beauvoir's work both applauded and criticized by feminist scholars offers an important document for addressing the double discrimination based on gender and age, and has been influential in defining a feminist approach to the discussion of gender and age. With the graying of American feminists in the 1990s, age became a concern and Beauvoir's contribution to the area of age studies received recognition as an early contribution to the humanist exploration of the topic of aging. This article surveys interpretations of Beauvoir's work on aging by literary critics, feminist historians, and a gerontologist.     

Acquisition and maintenance of delayed matching-to-sample in tufted capuchin monkeys

Delayed matching-to-sample (DMTS) is a commonly used procedure to investigate short-term memory. For the study of functions of forgetting, the delay between the disappearance of the sample stimulus and appearance of choices is manipulated. The intertrial interval (ITI) is also varied to assess interference effects. Performance decrements have been observed as delay increases and, in some cases, performance recovery occurs when ITIs are increased. Other studies indicate that the higher the ITI/delay ratio, the greater the accuracy in DMTS. In this study, 2 experiments investigated DMTS performances of 3 tufted capuchin monkeys as function of delay and ITI. In Experiment 1, alternation of gradual increases of delay and ITI was effective in producing ≥90% accuracy at delays as long as 90 s. Individual monkeys differed in the highest value of delay at which this criterion was met. In Experiment 2, the monkeys were exposed to 5-s DMTS with different ITIs to assess the effects of various ITI/delay ratios on accuracy. Highest accuracy tended to occur at the higher ITI/delay ratios.
