The present study examined children's understanding of illness in a peri-urban community in South Africa where AIDS is prevalent. Results suggest that children were surprisingly knowledgeable about AIDS at an early age, and may have even erroneously analogized from AIDS to the flu. Furthermore, all age groups attributed different causes for AIDS and flu. However, although factual knowledge about AIDS was identified among all age groups, there was no evidence of understanding biological causal mechanisms. The data have implications both for (...) developmental research on biological reasoning in diverse cultural contexts and for the design of health education programs. (shrink)

Are bilingualism and/or biculturalism good for a person’s positive well being? A growing number of studies have shown different positive outcomes of being exposed to two cultures or speaking two languages respectively, but the benefits of being both bilingual and bicultural have rarely been investigated theoretically or empirically. The purpose of this paper is to summarize the main beneficial outcomes of bilingualism and biculturalism, and to integrate these benefits into a new conceptual framework: Positive Bilingualism and Biculturalism GEAR model. The (...) GEAR model suggests that the beneficial outcomes of bilingualism and biculturalism can be systematically classified into four positive dimensions (psychological Growth; cognitive Exploration; linguistic Awareness; and social Reinforcement), in which there are dynamic interactions among these four dimensions. The hypothetical GEAR model provides an intricate theoretical approach to understand the potential benefits to an individual of experiencing more than one language and one culture in their life. The proposed model in this research offers a systematic framework for conducting future research to examine whether bilingualism and biculturalism accrue benefits to the individual. (shrink)

Has language developed to serve as a system of communication or one of thought? While language is clearly an excellent tool for communication, the possible contribution of higher order cognitive processes other than language to communication may provide insights on how we think about language evolution. Studies show that bilingualism improves communication skills, possibly due to boosting domain general processes, thus suggesting a divide between communication and formal language. However, to date little attention has been paid to bilingual atypical child (...) populations presenting asymmetric developmental delays in language and communication skills. In this study, we explore the language-communication divide in bilingual and monolingual children diagnosed with High Functioning Autism (HFA), displaying primary communication difficulties, and those with Specific Language Impairment (SLI), displaying primary language difficulties. Children were tested on language, cognitive control, Theory of Mind (ToM), social comprehension and verbal communication. Results demonstrate that bilingual children with HFA exhibit enhanced cognitive control, ToM and social comprehension, which in turn improve their verbal communication as compared to their monolingual peers with HFA. On the other hand, no boost emerges in bilingual children with SLI, be it in cognitive control or ToM, though a weaker advantage (relative to the children with ASD) can be observed in their verbal communication skills, with significant mediation from social comprehension. The overall evidence suggests that language, though useful for communication, is not sufficient for communication, and may arguably not have evolved primarily for communicative purposes. (shrink)

In the present study, we use a training design in two experiments to examine whether bilingual language switching facilitates two components of cognitive control, namely monitoring and inhibitory control. The results of Experiment 1 showed that training in language switching reduced mixing costs and the anti-saccade effect among bilinguals. In Experiment 2, the findings revealed a greater decrease of mixing costs and a smaller decrease of the anti-saccade effect from pre- to post-training for the language switching training group compared to (...) the L2 training group. Overall, the results suggest that extensive exercise in monitoring and inhibitory control among languages in an experimental setting may enhance the corresponding components of cognitive control. We discuss these findings in the context of the relationship between bilingual language control and executive control. (shrink)

The past 25 years have witnessed an increasing awareness of the importance of cognitive control in the regulation of complex behavior. It now sits alongside attention, memory, language, and thinking as a distinct domain within cognitive psychology. At the same time it permeates each of these sibling domains. This introduction reviews recent work on cognitive control in an attempt to provide a context for the fundamental question addressed within this topic: Is cognitive control to be understood as resulting from the (...) interaction of multiple distinct control processes, or are the phenomena of cognitive control emergent?

We examined the role of verbal mediation in planning performance of English–Spanish-speaking bilingual children and monolingual English-speaking children, between the ages of 9 and 12 years. To measure planning, children were administered the Tower of London (ToL) task. In a dual-task paradigm, children completed ToL problems under three conditions: with no secondary task (baseline), with articulatory suppression, and with non-verbal motor suppression. Analyses revealed generally shorter planning times for bilinguals than monolinguals but both groups performed similarly on number of moves (...) and execution times. Additionally, bilingual children were more efficient at planning throughout the duration of the task while monolingual children showed significant gains with more practice. Children’s planning times under articulatory suppression were significantly shorter than under motor suppression as well as the baseline condition, and there was no difference in planning times between monolingual and bilingual children during articulatory suppression. These results demonstrate that bilingualism influences performance on a complex EF measure like planning, and that these effects are not related to verbal mediation. (shrink)

Bilingual speakers have often been found to be superior in taking the perspective of another person. Also, females are commonly found to have enhanced perspective taking abilities compared with males, with male PT being generally more easily affected by external factors. The present study investigated whether bilingualism improves PT in males more strongly than in females. In total, 108 bilingual and 108 matched monolingual adults, with equal numbers of males and females, filled in the PT subscale of the Interpersonal Reactivity (...) index. While monolinguals showed the typical result of females scoring higher on PT than males, scores of male and female bilinguals did not differ, with both bilingual groups scoring as high as female monolinguals. Thus, bilingualism enhanced self-reported PT only in males, suggesting that male PT can be enhanced through socialization. (shrink)
