Dynamic orientation cues decrease the viewpoint cost of mental rotation

Mental rotation, as a covert simulation of motor rotation, could benefit from spatial updating of object representations. We are interested in what kind of visual cue could trigger spatial updating. Three experiments were conducted to examine the effect of dynamic and static orientation cues on mental rotation, using a sequential matching task with three-dimensional novel objects presented in different views. Experiment 1 showed that a rotating orientation cue with constant speed reduced viewpoint costs in mental rotation. Experiment 2 extended this effect with a varied-speed rotating orientation cue. However, no such benefit was observed with a static orientation cue in Experiment 3. These findings indicated that a visually continuous orientation cue is sufficient to elicit spatial updating in mental rotation. Furthermore, there may be differences in the underlying mechanisms of spatial updating on the basis of constant-speed rotating cues and varied-speed rotating cues.     

Les interventions préventives en santé mentale du jeune enfant vues par leurs bénéficiaires : l’exemple du projet CAPEDP

ObjectiveHome-visiting programs have become one of the most popular early childhood interventions, though their impact on parents and children remain uncertain. Outcomes measures often rely on experimental quantitative design and little space is offered for the voices of those served by these interventions. This paper presents the results of a qualitative protocol performed by the research team with participants in the CAPEDP project which took place in France from 2005 to 2011.MethodAll 184 women who had accepted at least one home visit in the CAPEDP programme were contacted and invited to participate. Individual and group interviews were conducted with the first 16 who accepted to participate. The semi-structured interview schedule addressed their overall appreciation of the project, their initial concerns, the quality of their relationship with their home visiting psychologist, positive and negative aspects of the intervention and any recommendations they might have for future interventions. Interviews were recorded, transcribed and anonymised. An inductive categorical thematic analysis was performed by the research team.ResultsParticipants expressed overall satisfaction with the CAPEDP intervention, underlining the quality of the relationships with the home visitors, usefulness of parental guidance, the fact that the intervention could be adapted to suit their own personal agenda, routine and needs, the importance of learning how to accept help and give help to others. Less positive aspects included the fact that the home visitors were not mothers themselves and that they lacked technical experience, the difficulty ending the relationship at the end of the 27-month project, insufficient integration of fathers, the difficult and time-consuming evaluation protocol and the lack of interaction with other parents during the intervention.ConclusionAlthough mothers who accepted to participate in the qualitative interview schedule may have had a more positive overall experience of the CAPEDP project than those who declined to participate, participants’ points of view provide potentially useful indications for adapting future home-visiting programs to the French context.     

The recognition of mental states from dynamic and static facial expressions

The ability to recognize mental states from facial expressions is essential for effective social interaction. However, previous investigations of mental state recognition have used only static faces so the benefit of dynamic information for recognizing mental states remains to be determined. Experiment 1 found that dynamic faces produced higher levels of recognition accuracy than static faces, suggesting that the additional information contained within dynamic faces can facilitate mental state recognition. Experiment 2 explored the facial regions that are important for providing dynamic information in mental state displays. This involved using a new technique to freeze motion in a particular facial region (eyes, nose, mouth) so that this region was static while the remainder of the face was naturally moving. Findings showed that dynamic information in the eyes and the mouth was important and the region of influence depended on the mental state. Processes involved in mental state recognition are discussed.     

Rehabilitative Beit Midrash as a means for advancing the community integration of Ultra Orthodox Jewish persons with severe mental illness

ABSTRACT

Religious Jews with severe mental illness often encounter barriers to involvement in religious activities in their community affecting their ability to become integrated into their community. Therefore, a study was conducted in Israel examining the contribution to community integration through a programme providing religious persons with mental illness an opportunity to participate in religious studies. An A-B research design was implemented among 42 Ultra-Orthodox Jewish persons with severe mental illness utilising a culturally-oriented structured instrument. The study showed that the opportunity for involvement in religious studies could advance the participants’ sense of social interaction in their community as well as their sense of psychological integration with other religious people. It also strengthened their confidence in their ability to further get involved in religious studies in the community. Rehabilitation services providing persons with severe mental illness an opportunity for involvement in religious studies can act as a springboard for advancing their community integration.     

Correlation of motor skill,mental rotation,and working memory in 3- to 6-year-old children

A relationship between motor processes and mental rotation has been suggested by current research; however, the influence of working memory on this relationship has not yet been determined. Therefore, a correlation between motor tests, paper–pencil and chronometric mental rotation tests, and working memory tests were conducted in 3- to 6-year-old children. A stepwise multiple-regression showed that 55.5% of the variance was explained by the working memory tests: digit span forward and Corsi forward. This indicates that working memory and executive functions may play an important role in mental rotation and motor processes.     

Response demands and the recruitment of heuristic strategies in syllogistic reasoning

Two experiments investigated whether dealing with a homogeneous subset of syllogisms with time-constrained responses encouraged participants to develop and use heuristics for abstract (Experiment 1) and thematic (Experiment 2) syllogisms. An atmosphere-based heuristic accounted for most responses with both abstract and thematic syllogisms. With thematic syllogisms, a weaker effect of a belief heuristic was also observed, mainly where the correct response was inconsistent with the atmosphere of the premises. Analytic processes appear to have played little role in the time-constrained condition, whereas their involvement increased in a self-paced, unconstrained condition. From a dual-process perspective, the results further specify how task demands affect the recruitment of heuristic and analytic systems of reasoning. Because the syllogisms and experimental procedure were the same as those used in a previous neuroimaging study by Goel, Buchel, Frith, and Dolan (2000), the result also deepen our understanding of the cognitive processes investigated by that study.     

Error adaptation in mental arithmetic

Until now, error and conflict adaptation have been studied extensively using simple laboratory tasks. A common finding is that responses slow down after errors. According to the conflict monitoring theory, performance should also improve after an error. However, this is usually not observed. In this study, we investigated whether the characteristics of the experimental paradigms normally used could explain this absence. More precisely, these paradigms have in common that behavioural adaptation has little room to be expressed. We therefore studied error and conflict adaptation effects in a task that encounters the richness of everyday life's behavioural adaptation—namely, mental arithmetic, where multiple solution strategies are available. In accordance with our hypothesis, we observed that posterror accuracy increases after errors in mental arithmetic. No support for conflict adaptation in mental arithmetic was found. Implications for current theories of conflict and error monitoring are discussed.     

Response selection influences inhibition of return

Previous work has suggested that there may be a relationship between the magnitude of inhibition of return (IOR) and the number of possible responses in the perceptual‐motor task. To test this possibility, the present experiment used a display that contained four horizontally aligned cue/target locations. In different blocks of trials, subjects responded to the target either with a one‐response detection key press, a two‐response localisation key press, or a four‐response localisation key press. The results showed the largest magnitude of IOR was found in the one‐response condition and the least in the four‐response condition. These results suggest that IOR may be most effective in inhibiting relatively prepotent responses and the inhibitory effect weakens when responses require more intricate sensorimotor mappings.
