Effets du bilinguisme précoce sur la flexibilité représentationnelle et procédurale dans le dessin du bonhomme

The present research aims to evaluate representational and procedural flexibility by comparing the performances of simultaneous bilingual children French-Arabic (n = 28), successive bilingual children Tamil-French (n = 21) and French monolinguals (n = 24) at 5 years old and at 8 years old educated, in public school, in a disadvantaged neighborhood. The paradigm of the man that does not exist (Karmiloff-Smith, 1990) has been proposed to measure the ability to introduce graphic innovation into a familiar production and drawing a man by starting with the foot (Baldy, 2010) was used to evaluate the ability to make an usual pattern in an unusual way. The results show that bilingual children as young as 5 years old produce significantly more inter-categorical innovations than their monolingual peers while in monolingual children this capacity doesn’t appear until 8 years old. In procedural representations, the results are more nuanced. The underlying mechanisms that explain the best performance of bilingual children are discussed.     

Would you rather teleport or spend some time commuting? Investigating individuals’ teleportation preferences

The “teleportation test” is a unique question—used in some travel behavior research since the 2000s—to examine individuals’ perceptions towards travel time and affinities for travel. It gives people a hypothetical choice between teleporting or spending some time traveling. All studies (using different methods, including focus groups, interviews, and questionnaires) have consistently reported high teleportation preferences (about 70%). Yet, few correlates of teleportation preferences (especially sociodemographic and perceptual characteristics) have been investigated. Using data from an online questionnaire of 648 commuters in Portland, Oregon, this study investigated factors affecting individuals’ teleportation preferences. While generally representative of the area’s commuters, the sample did have higher shares of high-income workers and people using active modes or transit. Overall, 62% of respondents preferred to teleport than to spend some time commuting. Results from binary logit models identified actual commute duration, typical mode of travel, and “ideal” travel time (but no demographic attributes) as major predictors of preferences to teleport. As expected, people with longer commute durations had a greater desire to teleport, whereas bicyclists and pedestrians more often preferred to commute. People with longer ideal travel times had a greater affinity to commute and were less keen to teleport. Analysis of follow-up questions exploring reasons for respondents’ answers suggested that most “teleporters” were motivated by saving time to do other things, while most “commuters” found parts of their commutes to be enjoyable or productive. Findings from this study are consistent with related studies in implying that a teleportation preference does not necessarily represent zero ideal travel time or viewing travel time as wasted. Finally, this study discusses several travel behavior policy implications of the teleportation test, along with limitations and areas for future research.
