Observed need-supportive and need-thwarting teaching behavior in physical education: Do teachers' motivational orientations matter?

ObjectivesThe behaviors physical education (PE) teachers engage in affect a number of important student outcomes. Therefore, it is essential to study the antecedents of these teaching behaviors.Design and methodGrounded in Self-Determination Theory, this cross-sectional study explored the relations between PE teachers' autonomous and controlled motivational orientations and a variety of observed need-supportive and need-thwarting teaching behaviors in 79 PE classes by means of regression analyses.ResultsControl-oriented teachers made less use of an overall need-supportive teaching style and provided less structure during the activity in particular, while they engaged in more need-thwarting teaching behavior in general and in more controlling and cold teaching behavior in particular.ConclusionAlthough autonomy-oriented teachers tended to display the opposite pattern of correlates, these associations were non-significant. As the current findings suggest that teachers' actual teaching behavior is rooted at least partly in their own dispositional motivational orientation, they may inform the design of effective continuous professional development programs and interventions aimed at enhancing teachers' need-supportive teaching. Directions for future research are discussed.     

Consistent and Variable Practice Conditions: Effects on Relative and Absolute Timing

The authors conducted the present experiments to resolve the discrepancy between studies in which relative-timing learning has been found to be enhanced by consistent practice conditions and contextual interference experiments in which relative-timing learning has been found to be enhanced more by random practice than by blocked practice. There were 40 participants in Experiment 1 and 48 in Experiment 2. The results of Experiment 1 extended previous findings: The learning of the relative-timing pattern was systematically enhanced by the degree to which the practice conditions promoted movement consistency (constant > blocked > serial > random). Experiment 2 provided evidence that the discrepancy between the relative-timing effects in the 2 groups of studies was a product of the way in which relative-timing goals and feedback were presented. When the feedback was presented as segment times, random practice resulted in generally more stable relative-timing patterns during acquisition than blocked practice did. Thus, in both experiments, the learning of the relative-timing pattern was enhanced by more stable relative-timing conditions during acquisition. Absolute-timing learning, as indexed by the transfer tests, was enhanced by serial or random practice as compared with constant or blocked practice, and was relatively unaffected by feedback conditions directed at the relative-timing pattern. In terms of motor programming theory, those findings are taken as additional evidence for the disassociation of memories supporting generalized motor program (GMP) performance, as indexed by relative timing, and parameter performance, as indexed by absolute timing.     

The effect of perceptual load on attention-induced motion blindness: the efficiency of selective inhibition

Recent visual marking studies have shown that the carry-over of distractor inhibition can impair the ability of singletons to capture attention if the singleton and distractors share features. The current study extends this finding to first-order motion targets and distractors, clearly separated in time by a visual cue (the letter X). Target motion discrimination was significantly impaired, a result attributed to the carry-over of distractor inhibition. Increasing the difficulty of cue detection increased the motion target impairment, as distractor inhibition is thought to increase under demanding (high load) conditions in order to maximize selection efficiency. The apparent conflict with studies reporting reduced distractor inhibition under high load conditions was resolved by distinguishing between the effects of "cognitive" and "perceptual" load.     

Similar minds in the family: COVID-19 centrality and relationship quality

We examined whether perceived similarity in COVID-19 centrality (i.e., the extent to which one thinks of the pandemic as shaping current and future life) is associated with family relationship quality during the pandemic. Thinking that other family members are similar to oneself regarding the pandemic's centrality may improve the quality of family relationships. We collected data from Turkish family triads (i.e., mother, father, 18–25 years old child) and had 481 participants from 180 families. Participants rated their similarity in COVID-19 centrality with the other two family members and reported the general and daily quality of their relationship with them (relationship satisfaction, closeness, conflict). We analyzed the data using the Social Relations Model. We found that family members who, on average, perceived more similarity in COVID-19 centrality reported higher levels in positive attributes of general relationship quality (i.e., satisfaction and closeness). The effects on conflict and daily relationship quality were less conclusive. This research confirms that family members' reactions during the COVID-19 pandemic are interdependent. Perceiving that other family members are of similar minds about the centrality of the pandemic relates positively to some aspects of relationship quality.     

Politics on the move: The democratic control of the design of sustainable technologies

This article examines how “design rationality” could help remediate the controversy over environmental degradation. Drawing on the case of designing sustainable forms of traffic management, it argues that this will only be effective to a limited degree. “Policy conversation” does indeed take place but within a coalition of actions that pushes a particular set of solutions. This facilitates due procedure but erodes political legitimacy, thus potentially reproducing an intractable controversy. The article suggests a five-phase model of democratic control as an alternative. He primarily works in the field of sociology of technology and environment. He is presently involved in a research project on the social redefinition of mobility, analyzing the translation of sustainable development into new institutional arrangements.     

Sahlqvist's theorem for boolean algebras with operators with an application to cylindric algebras

For an arbitrary similarity type of Boolean Algebras with Operators we define a class ofSahlqvist identities. Sahlqvist identities have two important properties. First, a Sahlqvist identity is valid in a complex algebra if and only if the underlying relational atom structure satisfies a first-order condition which can be effectively read off from the syntactic form of the identity. Second, and as a consequence of the first property, Sahlqvist identities arecanonical, that is, their validity is preserved under taking canonical embedding algebras. Taken together, these properties imply that results about a Sahlqvist variety V van be obtained by reasoning in the elementary class of canonical structures of algebras in V.We give an example of this strategy in the variety of Cylindric Algebras: we show that an important identity calledHenkin's equation is equivalent to a simpler identity that uses only one variable. We give a conceptually simple proof by showing that the first-order correspondents of these two equations are equivalent over the class of cylindric atom structures.Presented byIstván Németi     

Constrained maximization reconsidered — An elaboration and critique of Gauthier's modelling of rational cooperation in a single prisoner's dilemma

Gauthier's argument for constrained maximization, presented inMorals by Agreement, is perfected by taking into account the possibility of accidental exploitation and discussing the limitations on the values of the parameters which measure the translucency of the actors. Gauthier's argument is nevertheless shown to be defective concerning the rationality of constrained maximization as a strategic choice. It can be argued that it applies only to a single actor entering a population of individuals who are themselves not rational actors but simple rule-followers. A proper analysis of the strategic choice situation involving two rational actors who confront each other shows that constrained maximization as the choice of both actors can only result under very demanding assumptions.     

Monocular discrimination of rigidly and nonrigidly moving objects

Wemeasured thresholds for the monocular discrimination of rigidly and nonrigidly moving objects defined by motion parallax. The retinal projections of rigidly moving objects are subject to certain constraints. By applying smooth 2-D transformations to the projections of rigidly moving objects, we created stimuli in which these constraints were affected. Thresholds for (generic) nonrigid transformations that in theory can be detected from rigid ones by processing pairs of views depended not only on the extent to which the rigidity constraints were affected, but also on the structure and the movement of the simulated object. Nonrigid transformations under which every three successive views had a rigid interpretation were not discriminable from rigid transformations, except in cases where the distortions were very large. Under the rigidity assumption, this would mean that a large class of nonrigidly moving objects is erroneously perceived as rigidly moving.
