Sources of evaluation of parental behaviors as predictors of achievement outcomes

Parents contribute to their children’s academic achievements by supporting their basic psychological needs. Parents’ need supporting behaviors (NSB) were expected to predict positive academic outcomes such as students’ academic performance and persistence intentions. The present study tested the contribution of parental NSB by distinguishing which of the source of evaluation (parent or adolescent) or specific NSB (autonomy support, involvement, structure) was a better predictor of youths’ academic performance and persistence intentions. This prospective study used a sample of 435 mother–adolescent dyads and 246 father–adolescent dyads, who completed two questionnaires a year apart. Results suggested that poor agreement between sources precluded the adoption of a multitrait-multimethod model. Using distinct factors for mothers, fathers, and adolescents to evaluate each NSB, different predictions were found for each outcome. Our results showed stronger contributions for paternal behaviors than for maternal ones, from the perspective of both students and their parents. These findings are examined in light of theories and research on parenting and education.     

Quelle juridiction est compétente pour juger des faits commis par un professeur des universités-praticien hospitalier qui sont en rapport avec son activité d’enseignement ?

Constituted courts of ordinal authorities are not competent to judge facts committed by a university professor-hospital practitioner, which are related to his teaching activity. Only the court specific to hospital teachers, which is seized by the ministries of health and higher education, is competent to judge those facts.     

Teachers’ sense of responsibility for educational outcomes and its associations with teachers’ instructional approaches and professional wellbeing

Teachers’ formal accountability and duties have been the focus of high-stakes educational reforms, for instance in the context of national accountability systems. Yet, teachers’ sense of personal (rather than formal) responsibility and willingness to assume responsibility for their teaching and students remains an understudied area. The main purpose of this study was to investigate contextual and person-specific predictors of teachers’ sense of personal responsibility, as well as the potential implications of teachers’ personal responsibility for their instructional approaches and wellbeing. A path analysis indicated that high school teachers (n = 287) who felt responsible for their teaching and students reported higher levels of work engagement and job satisfaction than less responsible teachers, and were more likely to endorse mastery-oriented instructional practices that emphasized student effort, task mastery, and individual growth. Teachers’ perceptions of their school’s social climate (teachers’ evaluations of their relationships with students), their sense of teaching self-efficacy, and incremental beliefs of intelligence emerged as positive predictors of teacher responsibility. Teacher responsibility partially mediated the positive effects of these predictors on teachers’ wellbeing and mastery-oriented instructional practices. The results suggest that both contextual (e.g., school climate) and person-specific (e.g., self-efficacy) factors can contribute to teachers’ sense of personal responsibility, and that responsibility, in turn, can have positive implications for teachers’ wellbeing and instructional practices. Directions for future research and practical implications are considered.

Motor prediction at the edge of instability: alteration of grip force control during changes in bimanual coordination

Predicting the consequences of actions is fundamental for skilled motor behavior. We investigated whether motor prediction is influenced by the fact that some movements are easier to perform and stabilize than others. Twelve subjects performed a bimanual rhythmical task either symmetrically or asymmetrically (the latter being more difficult and less stable) while oscillating in each hand an object attached to an elastic cord. Motor prediction was monitored through the adequacy of anticipatory grip force adjustments with respect to the elastic resisting force. Results showed less adequate predictive control during asymmetrical movements (compared with symmetrical ones). Furthermore, switching between modes of coordination induced even larger alterations. An interesting finding was that grip force control did not always stabilize around the expected value after voluntary transition. We conclude that motor prediction is affected by the degree of coordination between the upper limbs and by phase transitions and is prone to carryover effects.     

Functional characterisation of the extrastriate body area based on the N1 ERP component

Electrophysiological and functional neuroimaging evidence points to the existence of neural populations that respond strongly and selectively to the appearance of the human body and its parts. However, the relationship between ERP and fMRI markers of these populations remains unclear. Here we used a previously identified functional dissociation between two body-selective regions identified with fMRI (extrastriate body area or EBA; fusiform body area or FBA) in order to better understand the source of a body-selective N1 ERP component. Specifically, we compared the magnitude of the N1 elicited by images of fingers, hands, arms and bodies to that obtained for hierarchically-matched control stimuli. We found close agreement between the pattern of body-part selectivity exhibited by N1, and the pattern of BOLD selectivity elicited in a previous study by the same type of stimuli in EBA (in contrast to FBA). We interpret these findings as evidence for EBA as the primary generator of the body-selective N1 component. Our results are an example of the use of functional criteria to distinguish among the possible neural sources of ERP markers.     

Does the olfactory cue activate the same brain network during aging in the rat after taste potentiated odor aversion retrieval?

Depending on the brain networks involved, aging is not accompanied by a general decrease in learning and memory capabilities. We demonstrated previously that learning and retrieval of taste potentiated odor aversion (TPOA) is preserved, and even slightly improved, in senescent rats showing some memory deficiencies in cognitive tasks (Dardou, Datiche, & Cattarelli, 2008). TPOA is a particular behavior in which the simultaneous presentation of odor and taste cues followed by a delayed visceral illness leads to a robust aversion towards both conditioned stimuli, which permits diet selection and animal survival. The present experiment was performed in order to investigate the stability or the evolution of the brain network underlying TPOA retrieval during aging. By using immunocytochemical detection of Fos and Egr1 proteins we mapped the cerebral activation induced by TPOA retrieval elicited by the odor presentation in the young, the adult and the senescent rats. The pattern of brain activation changed and the number of activated areas decreased with age. Nevertheless, the piriform cortex and the basolateral amygdala nucleus were always activated and seemed essential for TPOA retrieval. The hippocampus and the neocortical areas could have different implications in TPOA memory in relation to age. The patterns of expression of Fos and Egr1 were different, suggesting their differential involvement in TPOA retrieval. Data are discussed according to the possible roles of the brain areas studied and a model of schematic brain network subtending TPOA retrieval induced by the odor cue is proposed.     

Graphical representation fosters discovery in the 2-4-6 task

In the 2-4-6 rule discovery task, reasoners seek to discover a rule that governs the arrangement of three numbers (or triple). The to-be-discovered rule is “ascending numbers”. Upon being given the triple 2-4-6 as an initial example, however, reasoners tend to formulate algebraically specific hypotheses. Traditionally, this task is conducted primarily from an internal representation of the triples and candidate hypotheses. More recently, substantial representational effects have been demonstrated wherein an external representation of the dimensions of the problem space facilitated successful rule discovery. In the two experiments reported here, an interactive graphical representation was created by concurrently plotting each triple produced by the participants. In Experiment 1, participants who performed the task with this external representation were more likely to discover the rule than were a group of control participants. Experiment 2 replicated the effect but also assessed participants' hypotheses for each triple generated. Results indicated that a graphical representation of the triples fostered the development of hypotheses that were less constrained by the implied algebraic specificity of the initial triple.     

Summarizing digital documents: effects of alternate or simultaneous window display

We investigated the effect of window visibility on the computer‐based summarizing of digital documents. Two experiments studied the impact of the simultaneous or alternate display of the windows containing the notepad and source documents. In Experiment 1, the participants were asked to summarize the content of the source documents. In Experiment 2, they were required to copy out sections of the source documents. The results showed that in the alternate condition, the participants performed fewer reading and writing cycles than in the simultaneous condition. Furthermore, in the alternate condition, the writing episodes were both more numerous and more effortful, while quality of the summaries produced using the copying strategy was also affected. These experiments highlight the need for writers to be able to navigate freely and easily between the windows so that they can construct an overall mental representation of their summaries.
