Neurofunctional (re)organization underlying narrative discourse processing in aging: evidence from fNIRS

Relatively few studies have analyzed the mechanisms underlying the cognitive changes that affect language in the elderly, and fewer have done so for narrative discourse. The goal of this study was to explore the neurofunctional changes associated with aging for different components of narrative discourse. Functional near-infrared spectroscopy (fNIRS) and behavioral data on 10 younger adults and 10 healthy elderly participants were collected. Ten younger adults in a non-proficient second language condition were included to explore the possibility that the age-related neurofunctional reorganization partly expresses demanding resource allocation. Results show within- and across-hemispheric differences in the neurofunctional pattern of activation in the older participants with reference to the younger ones, partially shared with the low-proficiency young adults, providing support for the recognized mechanisms underlying neural reserve and compensation. fNIRS was shown to be appropriate for studying the age-related neurofunctional reorganization of complex cognitive abilities.     

Dealing efficiently with emotions: acceptance-based coping with negative emotions requires fewer resources than suppression

Previous studies have consistently shown that changing or avoiding emotions requires resources and therefore leads to impaired performance on a subsequent self-control task. The aim of the present study was to investigate the extent to which acceptance-based coping requires regulatory resources. Participants who accepted their emotions during exposure to a sad video performed better on a subsequent self-control task than participants who were instructed to suppress their emotions and a control group who received no instructions. These findings suggest that acceptance is an efficient strategy in terms of resources.     

Early Termination from Couple Therapy in a Naturalistic Setting: The Role of Therapeutic Mandates and Romantic Attachment

Drawing on a series of 141 couple therapy cases, the main goal of the present study was to determine whether romantic attachment, pre-treatment relationship distress and therapeutic mandates (i.e., reduction of couple distress or ambivalence resolution) are prognostic indicators of early termination. Couples completed the Dyadic Adjustment Scale (Spanier 1976) and the Experiences in Close Relationships Questionnaire (Brennan et al. 1998) at intake, whereas therapists filled in the Classification of Therapeutic Mandates (Poitras-Wright and St-Père 2004) after the 4th session. Results showed that an ambivalence resolution mandate, elevated couple distress and higher levels of attachment anxiety were associated with early termination. The implications of these findings to further understand early termination in couple therapy are discussed.     

Assessment of Personality Organization in Couple Relationships: Factorial Structure of the Inventory of Personality Organization and Incremental Validity Over Neuroticism

Summary: Creative thinking was explored from several approaches to further understanding of the interrelationship of perception, personality, and cognition. College students (N = 45) were administered the Group Embedded Figures Test (GEFT), the Remote Associates Test (RAT), a questionnaire concerning RAT strategy, and two self-report scales. Field independent subjects were found to be significantly (p < .001) more creative than field dependents. Correlations between the RAT and GEFT and the self-report measures of conformity and creativity, while largely nonsignificant, were in the predicted directions. Results demonstrated that advanced strategy levels and insightful responses were significantly related to high performance on the RAT. Theoretical links between cognitive style and Piagetian concepts were discussed in regard to creative thought. Overall, these findings support the contention that the creative processes should be studied, not as isolated structures, but with relational and multifaceted emphasis.     

Phenomenology,psychopathology, and short‐term therapeutic outcome of 102 infants aged 0 to 12 months consecutively referred to a community‐based 0 to 3 mental health clinic

Infants ages 0 to 1 year consecutively referred for psychiatric treatment during the year 2005 were followed, and variables associated with diagnosis and short‐term outcome were assessed. Infants were evaluated using the Psychiatric Infant Navigator Chart and Evaluation that includes nosological diagnoses [Diagnostic Classification of Mental Health and Developmental Disorders of Infancy and Early Childhood, (DC 0–3), Zero to Three, 1994] as well as risk and protective factors, treatment procedure, and outcomes. Seventy‐six percent of the infants had an Axis I diagnosis, with anxiety disorders and a mixed disorder of emotional expressiveness being the most frequent. Twenty‐five percent had an Axis II diagnosis. Multiple correspondence analyses showed that two dimensions corresponding grossly to DC 0–3 Axes I and II emerged. They emphasized three clinical profiles characterized by (a) good infant functioning, parent's awareness of their own difficulties, and a good outcome; (b) moderate child symptoms, overinvolved relating, and a good/intermediate outcome; (c) severe child symptoms, underinvolved relating, and a less favorable short‐term outcome, signaling the risk for developmental disorders. Among the associated risk factors were cumulative parental stress, maternal psychopathology, and family dysfunction. Clinical implications of these findings indicated that infants under the age of 1 year who are referred for mental health evaluation and intervention are a heterogeneous group in terms of both severity and prognosis. Clinicians should differentiate subgroups of young children to detect those infants at risk for persistent psychopathology.     

Cyberbullying: youngsters' experiences and parental perception.

This paper describes a survey on the prevalence and nature of cyberbullying of and by youngsters and the parental perceptions. Two questionnaires, one for youngsters and one for their parents, were sent to 1,211 final-year pupils of primary schools and first-year pupils of all levels of secondary schools and their parents. Pupils completed the questionnaires in their classroom, and parents completed them at home. The results show that about 16% of the youngsters had engaged in bullying via the Internet and text messages, while about 23% of the youngsters had been victims of cyberbullying. Cyberbullying seems to be a rather anonymous, individualistic activity, which primarily takes place at home. The most frequently used nature of harassment were name-calling and gossiping. Youngsters mostly react to cyberbullying by pretending to ignore it, by really ignoring it, or by bullying the bully. Most parents set rules for their children about the way to they should use the Internet but are not really conscious of the harassments. They underestimate their own children's bullying behavior and have insufficient notion of their children as victims of bullying.     

Relative Deprivation and Social Identity in Times of Dramatic Social Change: The Case of Nurses1

In the present study, an integration of relative deprivation theory and social identity theory is proposed to account for people's reactions to dramatic changes affecting their daily lives. Data collected among nurses (n = 108) indicate that feelings of relative deprivation are influenced by different perceptions of organizational change. Path analysis shows that feelings of social relative deprivation derive from negative changes that are numerous, and that temporal relative deprivation is experienced as a result of negative changes that are rapid. In terms of the link between social identity and relative deprivation, 2 contrasting approaches were tested. Analyses support the view that in‐group identification acts as a precursor, rather than as a consequence, of relative deprivation.     

Motor maps, seizures, and behaviour

Atypically organised motor maps have been described in some people with epilepsy and we have modelled this in rats. Our goal is to more fully understand the mechanisms responsible for seizure-induced functional brain reorganisation and to reverse their effects. Here we present an overview of the relationship between neocortical motor maps, seizures, and interictal behaviour. To begin we summarise the observations of atypical motor maps with epilepsy and in animal models following experimentally induced seizures. Our novel experiments have established that motor map expansion is linked to a functional alteration of motor behaviour. Evidence for some of the putative brain mechanisms responsible for motor map size is discussed. Our successes reversing seizure-induced map expansion by two different methods are also briefly reviewed. Lastly, unanswered questions for possible future experimentation are posed.     

Intertrial pellets influence the acquisition and expression of timed appetitive responding in rats

Two experiments examined temporally based changes in the conditioned magazine-entries of rats when a target food pellet arrived at a fixed time before the termination of a conditioned stimulus. Both experiments found that increasing the rate of intertrial pellets systematically interfered with the rate of acquisition. When intertrial pellets were featured in acquisition, their omission on test trials also resulted in a very poorly expressed conditioned response. On test trials preceded by intertrial pellets, however, peak times in groups trained with intertrial pellets were shifted in a rightward direction under a long but not short interstimulus interval. This rightward shift was accompanied by a smaller standard deviation. Our key findings are best accommodated by real-time associative models.
