Order information in short-term memory and time estimation

In previous experiments, the amount of interference between time production and visual or memory search tasks was shown not to be related to the level of difficulty of the search task per se, but instead to the amount of processing in short-term memory required in the search task. The first experiment of the present study verified whether the amount of interference between time production and a short-term memory task may be related to the level of difficulty of the short-term memory task. Two versions of a memory task, with and without processing of order information, were combined with a temporal interval production task in a concurrent processing condition. As is shown in a control reaction time task, processing order information increased the level of difficulty of the memory search task. In the concurrent processing condition, the interference between short-term memory processing and time production was stronger when the level of difficulty of the short-term memory search task was increased by requiring that order information be processed. The results of Experiment 2 showed that the amount of interference between a similar short-term memory task and time production seems not to be related to the amount of order information that must be maintained during the time production task. This dissociation between the effects of processing and the maintenance of order information is compatible with a similar dissociation, observed in previous experiments, between the effects of processing and those of maintaining item information in short-term memory on concurrent time production.     

Improving generalisation skills in a neural network on the basis of neurophysiological data

The distribution of striate cortex cells exhibits a maximum number of cells tuned to vertical and horizontal orientations (Mansfield, 1974). This was interpreted as an adaptation of the visual system to the presence in the visual environment of greater amounts of vertical and horizontal information compared to information from other orientations (Keil & Cristobal, 2000). The present research confirms that vertical and horizontal orientations are, indeed, present in greater number in natural scenes. After normalization of the amount of information across all orientations, vertical information appeared to be better for bottom-up categorization. We demonstrate this using a connectionist autoassociator model of categorization used elsewhere in simulations of early infant categorization.     

Preschoolers' fantasy-reality distinctions of emotional events

Research suggests that emotions influence children's ability to discern fantasy from reality; however, reasons for this association remain unknown. The current research sought to better understand the mechanisms underlying children's distinctions by examining the roles discrete emotions and context have in 3- to 5-year-olds' evaluations of fantasy and reality. In Study 1, children's fantasy-reality distinctions of images depicting happy, frightening, or sad events were obtained under two conditions: Children responded freely or were motivated to respond accurately. When responding freely, older children reported that happy and sad fantastic and real events could occur but frightening events could not. When motivated to respond accurately, children's accuracy improved for fantasy but not for reality. Study 2 examined real events exclusively and found that children may lack the knowledge that frightening, but not happy or sad, real events can occur. The findings provide new insight into how emotions affect children's fantasy-reality distinctions.

SHALL WE DANCE? MUSIC AS A PORT OF ENTRANCE TO MATERNAL–INFANT INTERSUBJECTIVITY IN A CONTEXT OF POSTNATAL DEPRESSION

The present study introduces the concept of a mother–infant group therapy that makes use of music, singing, and moving to establish maternal–infant intersubjectivity. It was conducted in a residential mother–baby unit for mothers with postnatal depression and their infants over a 5‐week period. Maternal–infant intersubjectivity of four dyads in relation to the group dynamics were microanalyzed for Sessions 1 and 5. We made within‐session (i.e., beginning–middle–end) and between‐session (Session 1 vs. Session 5) comparisons for the number of intersubjectivity moments (ISMs), total time of intersubjectivity (IST), and the mean duration of ISMs on a dyadic (i.e., own mother/infant involved) and a nondyadic level (i.e., own mother/infant not involved). In addition, three ISM levels (degree of group contribution) were distinguished. The results indicated a significant increase of ISMs/IST from Session 1 to Session 5. Within‐session analyses showed that ISMs/IST significantly decreased through Session 1 and remained stable throughout Session 5. Intersubjectivity occurred mainly on ISM Level 1 during Session 1 and on ISM Level 3 during Session 5, suggesting increased dyadic autonomy and self‐efficacy. The results are discussed in relation to the musical characteristics of mother–infant dyads, music improvisation techniques, group processes, and intersubjective development.     

Genetic Counseling Practice in Next Generation Sequencing Research: Implications for the Ethical Oversight of the Informed Consent Process

The potential for next generation sequencing research (NGS) to generate individual genetic results could have implications for the informed consent process and the provision of genetic counseling. We undertook a content analysis of informed consent templates and guidelines produced by Canadian institutional review boards, purposively sampling documents used by researchers to obtain consent from participants in genetics studies. Our goal was to examine the extent to which the informed consent documents addressed genetic counseling and the return of individual genetic results. Our analysis reveals that the majority of informed consent documents did not mention genetic counseling while several did not mention the return of results. We found differences in the ways in which documents addressed availability of counseling, eligibility criteria for referral to a genetic counselor, genetic counselor involvement, provision of services to family members of participants and incidental findings. From an ethical standpoint, consent documents should provide appropriate information so that participants may make an informed decision about their participation in research. The need to ensure adequate counseling for study populations in an NGS research context will necessarily involve adapting values that underlie care in genetic counseling practice. If the interests of research participants are to be truly promoted, the drafting and review of informed consent documents should give proper due to genetic counseling.     

La qualité de vie au travail dans les services de ressources humaines

This research looks at work well-being for human resources staffs, which are brought to manage relations between individuals and organization, between organization and society, between individuals and society. 263 human resources staffs performed a questionnaire estimating work facets such professionals satisfaction and commitment, work conditions and health. Results shown firstly a work quality of life for staffs, what does not prevent them from reporting hardness (temporal constraints, working overload), secondly the absence of systematic effects of status, age and gender on work attitudes and health. Results and futur works are discussed.     

Transitions to Adulthood Among First Generation Sub-Saharan African Immigrant Adolescents in Canada: Evidence from a Qualitative Study in Montreal

In industrialized societies, a large number of studies have addressed the various patterns of adolescent transitions to adulthood. While most studies on migration have examined aspects of migrants’ integration into host societies, few researches, however, have dealt with the intersection of these two topics—the experiences and problems encountered by immigrant adolescents. This research focuses on the transition to adulthood among sub-Saharan African youth who live in Montreal, Canada. This group is still poorly known in Canada, and the few studies that exist on sub-Saharan Africans in Canada showed that they are among the most discriminated groups socially and economically. Both immigrant youth and their parents/families’ experience a transition to adapt to a new place, and these respective experiences may affect their relationships. Our research objectives are to examine the conditions in which African immigrant adolescents experience their transition to adulthood and to assess whether the gaps between the two perspectives are purely generational or are partly specific to this group. The data are based on qualitative focus group discussions and individual interviews conducted in Montreal in 2005–2007 among first generation immigrants from sub-Saharan Africa and a control group of native Canadians (whose parents were also born in Canada), men and women between age 12 and 18 and young adults aged 18 to 29. Our results show that in all cases the question of becoming responsible, making one’s own decision is central. What varies is the process through which the young people become responsible.
