Highs and Lows in Motor Control Development

Abstract

Motor control is classically described as relying on two components: anticipatory control (feedforward processing) and online control (feedback processing). Here we aimed to unveil the developmental steps of both feedback and feedforward control in 5–10 years old children, using a simple and ecological task. We manipulated object’s weight in a reach-to-displace paradigm. When the weight was known before lifting it, anticipatory processes were quantifiable during the reaching phase. Conversely, an unknown weight triggered online corrections during the displacing phase. Movement kinematics revealed that children anticipate this objet property as young as 5 y-o. This anticipation becomes adequate around 7 y-o and is paralleled by poor online corrections. This simple yet relevant paradigm should allow quantifying deviations from neurotypical patterns in disorders of motor control.     

Schema‐driven source misattribution errors: remembering the expected from a witnessed event

When recollection is difficult, people may use schematic processing to enhance memory. Two experiments showed that a delay between witnessing and recalling a visual sequence increases schematic processing, resulting in stereotypic memory errors. Participants watched a slide show of a man and a woman performing stereotype‐consistent and stereotype‐inconsistent actions, followed by an immediate or delayed memory test. Over a two‐day delay, stereotype‐inconsistent actions were increasingly misremembered as having been performed by the stereotype‐consistent actor (Experiment 1). All the source errors increased, regardless of stereotype consistency, when the wrong actor was suggested. When we merely suggested that ‘someone’ performed an action (Experiment 2), only stereotype‐consistent source errors were increased. Although visual scenes are typically well remembered, these results suggest that when memory fades, reliance on schemata increases, leading to increased stereotypic memory errors.

THE DILEMMA OF ERROR AND ACCURACY: AN EXPLORATION

This paper reports on the research on error and accuracy within the realms of constructivism, reading, and writing, and describes an exploratory study of teacher perceptions of approaches to addressing error and accuracy in literacy instruction. Findings demonstrate that teachers who self-reported that they were developing constructivist approaches to classroom instructional practices had contradictory beliefs about dealing with reading and writing errors. There were also contradictory beliefs about addressing reading and writing errors with more- and less-able readers and writers. The teachers were solid in their conviction that students' inaccurate constructions of knowledge should be corrected through inquiry, but were unable to provide examples of instances in which they had done so.     

Recognition of context and experience: a civic-based Canadian conception of religious literacy

ABSTRACT

Several conceptions of religious literacy exist globally and are informed by the contextual nuances of the scholars who developed them in the UK, US and Australia. As five Canadian scholar-educators across British Columbia, Alberta, Ontario and Quebec, we analyse the well-known religious literacy conceptions of Jackson, Nesbitt, Dinham, Moore and Crisp through a framework based on the recognition of context and experience. In doing so, we propose a Canadian-specific conception that considers the contextual nuances in these four provinces and relates to Canada as a nation and the individual experiences of each author, and recognises the diversity across Canada. We posit that our conception addresses the social and political dynamics and shifts in Canada, namely the changing demography of religious, spiritual and non-religious individuals and the response to the Truth and Reconciliation Commission report that calls Canadians and its institutions to respond to the wrong towards First Nations, Metis and Inuit people.
