Bridging the intention–behavior gap: Inducing implementation intentions through persuasive appeals

The potential of using implementation intentions—action plans that link a critical situational cue to a specific goal-directed behavior—to bridge the intention–behavior gap in consumer behavior has been limited by the practice of using explicit instructions to induce the construct. In two studies, we therefore tested the effectiveness of an indirect, persuasive strategy that benefits from the positive consequences of implementation intentions by ‘mimicking’ their underlying psychological processes. Experiment 1 showed that a strategy presenting vivid information on critical cues and appropriate behavioral responses affected mental imagery. Experiment 2 demonstrated that this strategy affected actual purchase behavior.     

Walking dreams in congenital and acquired paraplegia

To test if dreams contain remote or never-experienced motor skills, we collected during 6 weeks dream reports from 15 paraplegics and 15 healthy subjects. In 9/10 subjects with spinal cord injury and in 5/5 with congenital paraplegia, voluntary leg movements were reported during dream, including feelings of walking (46%), running (8.6%), dancing (8%), standing up (6.3%), bicycling (6.3%), and practicing sports (skiing, playing basketball, swimming). Paraplegia patients experienced walking dreams (38.2%) just as often as controls (28.7%). There was no correlation between the frequency of walking dreams and the duration of paraplegia. In contrast, patients were rarely paraplegic in dreams. Subjects who had never walked or stopped walking 4–64 years prior to this study still experience walking in their dreams, suggesting that a cerebral walking program, either genetic or more probably developed via mirror neurons (activated when observing others performing an action) is reactivated during sleep.     

Composer avec la diversité culturelle en classe de maternelle: résultats d’une analyse de récits de pratique enseignante

This article offers an analysis of teachers’ narrative within which kindergarten teachers have rebuilt their intercultural experience in the classroom, through a situation featuring a child "from another culture". The progressive scheduling in, oriented towards the ideal type of commitment to the child "of another culture", which led the analysis, will be presented and interpreted from two angles, therefore providing a definition of what we named the "otherness in act ", referring to some "enactment" of the paradigm of otherness (Abdallah Pretceille, 1996, 1999, 2003).     

The use of virtual reality for episodic memory assessment: effects of active navigation

Episodic memory was assessed using Virtual Reality (VR). Forty-four (44) subjects visualized a target virtual apartment containing specific objects in each room. Then they visualized a second virtual apartment comprised of specific objects and objects shared by the two apartments. Subjects navigated in the virtual apartments in one of the following two conditions: active and passive. Four main episodic memory components were scored from the VR exposures: (1) learning effect; (2) active forgetting effect; (3) strategies at encoding and at retrieval; and (4) false recognitions (FRs). The effect of navigation mode (active vs. passive) on each memory component was examined. Active subjects had better learning and retrieval (recognition hits) performances compared to passive subjects. A beneficial effect of active navigation was also observed on the source-based FR rates. Active subjects made fewer source-based FRs compared to passive subjects. These overall results for the effect of active navigation are discussed in terms of the distinction between item-specific and relational processing.     

Use of indirect addition in adults' mental subtraction in the number domain up to 1,000

This study examined adults' use of indirect addition and direct subtraction strategies on multi-digit subtractions in the number domain up to 1,000. Seventy students who differed in their level of arithmetic ability solved multi-digit subtractions in one choice and two no-choice conditions. Against the background of recent findings in elementary subtraction, we manipulated the size of the subtrahend compared to the difference and only selected items with large distances between these two integers. Results revealed that adults frequently and efficiently apply indirect addition on multi-digit subtractions, yet adults with higher arithmetic ability performed more efficiently than those with lower arithmetic ability. In both groups, indirect addition was more efficient than direct subtraction both on subtractions with a subtrahend much larger than the difference (e.g., 713 - 695) and on subtractions with a subtrahend much smaller than the difference (e.g., 613 - 67). Unexpectedly, only adults with lower arithmetic ability fitted their strategy choices to their individual strategy performance skills. Results are interpreted in terms of mathematical and cognitive perspectives on strategy efficiency and adaptiveness.     

Why Do Students Strike? Direct and Indirect Determinants of Collective Action Participation

The current project investigated affective and strategic determinants of participation in collective actions by taking a multidimensional approach to collective identity (see Cameron, 2004 ) and investigating rational decision‐making processes. A field study was conducted during an important student strike within the Canadian province of Quebec. One hundred and eighty four students attending the province's postsecondary francophone institutions participated in the study. Path modeling was used to investigate two channels to collective action participation. A direct path involved the affective dimensions of identification. An indirect strategic path revealed that pro‐action arguments allowed individuals to derive instrumental value, which in turn led them to participate in collective actions. This indirect influence only occurred at higher self‐control. The results and their implications for understanding participation in collective actions during social movements are discussed.     

Predictive Validity of the Suicide Probability Scale in a Male Inmate Population

This paper describes the predictive power of the Suicide Probability Scale (SPS) within a male inmate population. The SPS scores of 1,047 inmates from 1995 to 1996 were compared against their suicidal behaviors in the following 10 years. The SPS probability score and the scores on its four subscales were found to be significantly higher in the group that engaged in at least one of three types of suicidal behavior: suicide, non-lethal self-harm and serious suicidal intentions. However, the SPS did not discriminate the inmates who went on to commit suicide. The SPS’s capacity to predict suicidal behavior proved limited in terms of sensitivity. In this regard, the SPS’s low and high risk levels correctly identified 36% of inmates who later engaged in suicidal behavior. The specificity was 0.85. These results confirm the SPS’s predictive power with male prisoners. These findings are the first to demonstrate the predictive validity of the SPS.     

Étude qualitative de l’évolution des stratégies de faire face chez les parents d’adolescents atteints de troubles autistiques

Since their child has been diagnosed as having an autistic spectrum disorder (ASD), parents are confronted with important and chronic stress in their everyday life. To face it, they use coping strategies. Using qualitative analyse, this article exposes preliminary results on changes in coping strategies of ASD families and presents how parents manage to adjust their coping.
