The brain is a complex organ with an intellectual capacity that is unique to humans. For educators, it is wise to study the brain's many attributes and how it functions to help guide, inform, and improve teaching practice. Learners' brains are particularly sensitive to certain kinds of stimuli--that is social, physical, cognitive, and emotional…

Much of our human mental life looks to involve a seamless unfolding of perception, action and experience: a golden braid in which each element twines intimately with the rest. We see the very world we act in and we act in the world we see. But more than this, visual experience presents us with the world in a way apt for the control and fine…

This paper presents a cognitive approach to on-line spatial perception within scenes. A theoretical framework is developed, based on the idea that experience with a scene can activate a complex representation of layout that facilitates subsequent processing of spatial relations within the scene. The representations integrate significant, relevant…

Discusses six principles of visual perception and their cognitive implications for interactive screen design: clear perception determines continuity and flow of information; perceptual grouping establishes screen sequencing; placement of information aids recall; distinctiveness increases retention and retrieval; consistency in the perception of…

How do infants individuate and track objects, and among them objects belonging to their species, when they can only rely on information about the properties of those objects? We propose the Human First Hypothesis (HFH), which posits that infants possess information about their conspecifics and use it to identify and count objects. F. Xu and S.…

Discusses the size-weight illusion that occurs when a person lifts two equal-weight objects differing in size and perceives the larger object as lighter than the small object. Describes several inexpensive techniques for demonstrating the size-weight illusion and reviews some relevant issues concerning this phenomena. (MJP)

Outlines a simple classroom demonstration that illustrates Piagetian conservation. Piagetian conservation refers to the illusion of an increase in mass by changing an object's form. This demonstration, done by forming an ellipse with an extension cord, shows that college students are as susceptible to this effect as are young children. (MJP)
