How to keep children safe in traffic: find the daredevils early

Crossing the street in front of oncoming vehicles poses serious danger to young children. But is each young pedestrian similarly at risk? The authors aimed to identify children who are particularly prone to making risky and potentially harmful crossing decisions. They used a simple game involving risk to classify 5- to 6-year-olds as risk takers or risk avoiders. Children classified as risk takers made more crossing decisions at a busy 1-way street than risk avoiders, tolerated shorter time intervals between initiation of the crossing decision and arrival of the next vehicle, and were more likely to cause a (hypothetical) accident. Finally, they made decisions more quickly than risk avoiders. The authors discuss the implication of these results for traffic safety programs.     

L’entretien motivationnel,une nouvelle « panacée » dans la prise en charge de patients toxicodépendants ? Une revue de littérature

Motivational Interviewing (MI) is a therapeutic style well established in the field of treatment of substance disorders. It is defined as “a client-centered, directive method for enhancing intrinsic motivation to change by exploring and resolving client ambivalence” (Miller, W.R., Rollnick, S., 2002. Motivational interviewing: preparing people for change. The Guilford Press, New York, p. 25). After a brief theoretical introduction, this article proposes a review of efficacy and efficiency studies on motivational interviewing for substance abuse. Despite the growing evidence indicating that MI is effective, few studies have examined how MI exerts its effects (search for “active ingredients”). Some hypotheses about its mode of action are reviewed.

Is acoustic evaluation in a non-primate mammal,the tree shrew,affected by context?

Sound categorisation plays a crucial role for processing ecological and social stimuli in a species’ natural environment. To explore the discrimination and evaluation of sound stimuli in human babies and nonhuman primates, a reciprocal habituation-dishabituation paradigm has been successfully introduced into auditory research. We applied the reciprocal paradigm for the first time to a non-primate mammal, the tree shrew (Tupaia belangeri), to examine to what extent non-primate mammals share the ability to evaluate communication calls with primates. Playback stimuli were three types of communication calls, differing distinctively in context and acoustic structure, as well as two artificial control sounds, differing solely in frequency. We assessed the attention towards the playback stimuli by the latency to respond to the test stimulus. Subjects evaluated pairs of communication call types as well as the artificial playback stimuli. Attention towards the test stimuli differed significantly in strength for one pair of communication calls, with subjects dishabituating faster to one category than the other. The comparison of a second pair of communication calls did not show significant differences. Interestingly, subjects also evaluated the artificial control sounds. Findings are only partly in line with results on human and non-human primates. They provided first evidence that in non-primate mammals acoustic evaluation is not solely affected by the sound-associated context but is also linked to unusualness and acoustic cues, such as peak frequency.     

Different social motives in the gestural communication of chimpanzees and human children

Both chimpanzees and human infants use the pointing gesture with human adults, but it is not clear if they are doing so for the same social motives. In two studies, we presented chimpanzees and human 25-month-olds with the opportunity to point for a hidden tool (in the presence of a non-functional distractor). In one condition it was clear that the tool would be used to retrieve a reward for the pointing subject (so the pointing was selfish or 'for-me'), whereas in the other condition it was clear that the tool would be used to retrieve the reward for the experimenter (so the pointing was helpful or 'for-you'). The chimpanzees pointed reliably only when they themselves benefited, whereas the human children pointed reliably no matter who benefited. These results are interpreted as evidence for the especially cooperative nature of human communication.     

Using a Self-Management Intervention to Increase Compliance in Children With ASD

This two-study series examined the effectiveness of self-management in increase compliance with parental requests. Three boys diagnosed with Autism Spectrum Disorder and their parents participated. The intervention involved self-monitoring combined with parent-delivered reinforcement. A multiple baseline design was used. The intervention was successful in increasing rates of compliance and reducing problem behavior in training and generalization settings with each participant. Social validity was high and treatment integrity data indicated that the intervention could be readily implemented by parents. Study 2 also provided evidence of a strong treatment effect for the self-management beyond a small effect for effective instructional delivery.
