Speed of simple arithmetic in bilinguals

Four types of bilinguals solved simple addition problems that were auditorily presented in their preferred language, the language in which they first learned arithmetic, or in their nonpreferred language. Subjects responded in the language in which the problems were presented. Solution time averaged .227 sec faster in the preferred language and was an increasing linear function of the number of addition operations required. The intercepts of the preferred and nonpreferred language functions significantly differed, but the slopes did not. The preferred language advantage was attributed to faster encoding and/or response times in the preferred language. When bilinguals used only one of their languages in a given experimental session, encoding/response times in the two languages were equivalent and the preferred language advantage was eliminated.     

Stereotype Susceptibility: Identity Salience and Shifts in Quantitative Performance

Abstract—Recent studies have documented that performance in a domain is hindered when individuals feel that a sociocultural group to which they belong is negatively stereotyped in that domain. We report that implicit activation of a social identity can facilitate as well as impede performance on a quantitative task. When a particular social identity was made salient at an implicit level, performance was altered in the direction predicted by the stereotype associated with the identity. Common cultural stereotypes hold that Asians have superior quantitative skills compared with other ethnic groups and that women have inferior quantitative skills compared with men. We found that Asian-American women performed better on a mathematics test when their ethnic identity was activated, but worse when their gender identity was activated, compared with a control group who had neither identity activated. Cross-cultural investigation indicated that it was the stereotype, and not the identity per se, that influenced performance.     

Everyday executive function in focal onset pediatric epilepsy on the parent-report BRIEF2

Executive function (EF) difficulties are a core neuropsychological feature of pediatric epilepsy, and parent-report measures of EF concerns are an important complement to task-based EF measures. The Behavior Rating Inventory of Executive Function (BRIEF) has shown sensitivity to parent-reported EF concerns in epilepsy and other pediatric populations. We compared profiles of parent-reported EF concerns using the BRIEF and its revision, the BRIEF2, in 117 pediatric patients with focal onset epilepsy to examine the clinical utility of the revised scale. We then compared BRIEF2 profiles between patients and age- and gender-matched healthy controls. Among patients, profiles on the BRIEF did not globally differ from the BRIEF2, and agreement was very good across scales. Patients and controls differed significantly on the BRIEF2, with patients showing higher EF difficulties reported by parents across most scales. High rates of clinical elevation among patients emerged on the Task Monitor, Plan/Organize, Working Memory, and Shift scales. Younger age of epilepsy onset, chronic epilepsy, and right hemisphere seizure focus were associated with higher parent-reported EF concerns. Findings suggest that the BRIEF2 demonstrates similar performance to the BRIEF among pediatric patients with focal onset epilepsy who are most at risk in the areas of task monitoring, working memory, planning and organization, and flexibility. These findings are informative when comparing literature across versions and provide additional insight into the nature of parent-reported EF difficulties among children with focal onset epilepsy.     

The social construction of race: biracial identity and vulnerability to stereotypes

Multiracial individuals are more likely to have a heightened awareness of race as a social construct than monoracial individuals. This article examines the impact that a heightened awareness of race as a social construct has on the relationship between racial stereotypes and performance. Study 1 finds that multiracial individuals reported subscribing less to the notion that race biologically determines ability. Study 2 finds that monoracial individuals show stereotype activation, whereas multiracial individuals show stereotype inhibition in reaction to race salience. Study 3 draws on the work on stereotypes and performance to test the susceptibility of multiracial individuals to racial stereotypes about ability. The authors find that Asian/White and Black/White multiracial individuals were less susceptible to racial stereotypes than monoracial individuals. Whereas monoracial participants showed significant performance changes in reaction to race salience, multiracial individuals did not. Study 4 finds that emphasizing the social construction of race buffers individuals from stereotype threat effects.     

Measuring and modeling the trajectory of visual spatial attention

In a novel choice attention-gating paradigm, observers monitor a stream of 3 x 3 letter arrays until a tonal cue directs them to report 1 row. Analyses of the particular arrays from which reported letters are chosen and of the joint probabilities of reporting pairs of letters are used to derive a theory of attention dynamics. An attention window opens 0.15 s following a cue to attend to a location, remains open (minimally) 0.2 s, and admits information simultaneously from all the newly attended locations. The window dynamics are independent of the distance moved. The theory accounts for about 90% of the variance from the over 400 data points obtained from each of the observers in the 3 experiments reported here. With minor elaborations, it applies to all the principal paradigms used to study the dynamics of visual spatial attention.     

Stereotype performance boosts: the impact of self-relevance and the manner of stereotype activation

The activation of positive stereotypes has been shown to produce academic performance boosts. Evidence regarding the role of self-relevance in producing such effects has been mixed. The authors propose that the subtlety of stereotype activation plays a key role in creating performance boosts among targets and nontargets of stereotypes. Study 1 found that subtle stereotype activation boosted performance in targets, but blatant activation did not. Study 2 was conducted on both targets and nontargets using different methods of stereotype activation. Again, targets showed performance boosts when stereotypes were subtly activated but not when they were blatantly activated. Nontargets, however, showed boosts in performance only when stereotypes were blatantly activated. The role of self-relevance in mediating sensitivity to stimuli is discussed.     

Generation of a new Space

This paper addresses a significant gender issue in the Chinese religious culture of Taiwan. The exclusion of deceased maidens from family and ancestral lineages leaves relations between the living and the dead disordered. People believe that homeless maidens become restless, polluting ghosts after death who will bring misfortune to their family and others in society. The case study examined here is a correction to the exclusion/pollution/homelessness of maiden-spirits through ‘adoption’ in the maiden-temple of Sam-giap. I will analyse how spirit-adoption in the Sam-giap maiden-temple constitutes an attempt to correct that disorder and pollution. I will also argue that one result of the Sam-giap corrective practice is the generation of a new space for maiden-spirits in which a new category that disrupts the opposition of ghosts and ancestors emerges.     

Memory for details with self-referencing

Self-referencing benefits item memory, but little is known about the ways in which referencing the self affects memory for details. Experiment 1 assessed whether the effects of self-referencing operate only at the item, or general, level or whether they also enhance memory for specific visual details of objects. Participants incidentally encoded objects by making judgements in reference to the self, a close other (one's mother), or a familiar other (Bill Clinton). Results indicate that referencing the self or a close other enhances both specific and general memory. Experiments 2 and 3 assessed verbal memory for source in a task that relied on distinguishing between different mental operations (internal sources). The results indicate that self-referencing disproportionately enhances source memory, relative to conditions referencing other people, semantic, or perceptual information. We conclude that self-referencing not only enhances specific memory for both visual and verbal information, but can also disproportionately improve memory for specific internal source details.
