Title: Attending to Words and Objects and Remembering them in Order: How People Do This and How they May Differ

Speaker: Nelson Cowan (University of Missouri, US)

When people need to remember information about a series of things, there can be a difference between what they should do to remember the items themselves the best, and what they should do to remember the order in which these items occurred the best. There also may be a difference between what information is needed immediately and what information will be needed later. I will discuss my theoretical framework for thinking about these issues, stemming from a combination of activated elements of long-term memory, rapid new learning, and the focus of attention that is so critical in high-level processing. I will examine recent investigations into what information is picked up about items and their order, and how grouping strategies contribute to what is remembered. Then I will discuss some recent investigations into what processes of remembering appear to change with development during the elementary school years and what processes may differ in children with language and reading difficulties.

Title: A tale of two inhibitory aftereffects of orienting

Speaker: Raymond Klein (Dalhousie University, Canada; invited by Thomas Lachmann)

This is a personal story about an exciting phenomenon with an interesting function. I will begin by describing two scientific contexts, one methodological and one conceptual, into which I will place it. The methodological context is about achieving ecologically valid conclusions about behaviour; the conceptual context is a taxonomy of attention. The phenomenon is inhibition of return (IOR). I will describe: its discovery by Posner and his proposal that it might function as a novelty seeking mechanism; my earliest experiments on IOR, supporting Posner’s functional attribution by showing that it was present in the aftermath of serial but not pop-out search; my period of belief that my demonstration was wrong; how research by others and my “Where’s Wally” experiment(s) changed my mind; the seminal research of Taylor and Ivanoff which laid the seed for Hilchey’s realization that there were/are (at least) two inhibitory aftereffects of orienting; the converging evidence and computationally explicit model that Redden and others have generated to confirm this realization. We believe that both forms can serve as a foraging facilitator.  Let’s see if my story convinces you.

Title: Optimizing Movement Skill

Speaker: Gabriele Wulf (University of Nevada, Las Vegas, US) & Rebecca Lewthwaite (Rancho Los Amigos National Rehabilitation Center, Los Angeles, US)

Skilled motor performance is fundamental to many human activities, including sports, the performing arts, in various occupations (e.g., medical professions). What factors influence the quality of motor performance, and what practice conditions are necessary to optimize learning? Recently, we (Wulf & Lewthwaite, 2016) published the OPTIMAL (Optimizing Performance Through Intrinsic Motivation and Attention for Learning) theory of motor learning. The theory is based on numerous studies that have demonstrated the importance of motivational and attentional factors for effective learning and performance, movement efficiency, balance, force production, and artistry. Key factors include: (a) enhanced expectancies for future performance or anticipated positive experience, (b) support for performer autonomy, and (c) an external focus of attention. These factors align thoughts, attention, motivation, and neuromuscular activity to the performer’s goals. Evidence from various lines of research indicates that enhancing performance expectancies facilitates learning. Furthermore, providing learners with some measure of control, or supporting their need for autonomy, has consistently been found to enhance both performance and learning. The sense that one is in a situation in which one has control over one’s actions reduces the need to resist, and enhances expectations for future success. Finally, directing attention to the intended movement effects (external focus), rather than the coordination of body movements (internal focus), results in more effective performance and learning. Thus, pairing motor practice with conditions that boost confidence and outcome expectations, support performers’ autonomy, and focus their attention on external movement effects facilitates learning. These conditions lead to efficient goal-action coupling. They arguably play a role in recovery from injury as well, in that they allow fuller engagement in challenging rehabilitation activities and a beneficial external focus on coordinated goal-directed movement activity. In this presentation, we review key findings and discuss implications for establishing conditions that optimize skill learning, enhance dance performance, and have the potential to reduce injuries and speed the rehabilitation process.

Title: What is "optimal" brain development? It depends on a child's environment

Speaker: Silvia Bunge (Berkeley University of California, US; invited by Daniela Czernochowski)

There has been an explosion of research on human brain development over the past 20 years. As a result, we have learned a lot about the features of brain anatomy and brain function that change over childhood and adolescence and that help to explain individual differences in cognition, affect, and behavior. However, the vast majority of brain imaging study samples skew towards middle- or higher-income individuals; we know next to nothing about how the brain develops in children living in poverty. Here, I describe a pattern of brain communication that has been shown in a number of studies to be associated with better cognitive performance – and then show how this finding does not generalize to children living below the poverty line. This work serves as a reminder that biological features that are adaptive for one population may not be for another.
