“…Otherwise, processing rates differed between participants, which precluded a simple interpretation of processing rates in terms of dimensional salience, as suggested by Lamberts (1995). Although the rate of information accumulation is almost certainly influenced by physical salience (Bundesen, 1990;Eriksen & Schultz, 1977;Hoffman & Singh, 1997;Lamberts, 1995Lamberts, , 1998, other factors may be important as well. For instance, Btmdesen's theory assumes that processing rates also depend on attention, in that attended elements are processed faster than nonattended elements.…”

A process model of perceptual categorization is presented, in which it is assumed that the earliest stages of categorization involve gradual accumulation of information about object features. The model provides a joint account of categorization choice proportions and response times by assuming that the probability that the information-accumulation process stops at a given time after stimulus presentation is a function of the stimulus information that has been acquired. The model provides an accurate account of categorization response times for integral-dimension stimuli and for separable-dimension stimuli, and it also explains effects of response deadlines and exemplar frequency.The time course of perceptual categorization has recently become the topic of much research (e.g

“…Silhouette features are believed to be the first index into the human memory of shapes [Hoffman and Singh 1997], and, as a direct result of Shannon's information theory, it was known as early as the 1950's that edges and contours contain a wealth of information about a 3D shape [Attneave 1954;Koenderink and Doorn 1979]. a 4 : Silhouette length.…”

The question of what are good views of a 3D object has been addressed by numerous researchers in perception, computer vision, and computer graphics. This has led to a large variety of measures for the goodness of views as well as some special-case viewpoint selection algorithms. In this article, we leverage the results of a large user study to optimize the parameters of a general model for viewpoint goodness, such that the fitted model can predict people's preferred views for a broad range of objects. Our model is represented as a combination of attributes known to be important for view selection, such as projected model area and silhouette length. Moreover, this framework can easily incorporate new attributes in the future, based on the data from our existing study. We demonstrate our combined goodness measure in a number of applications, such as automatically selecting a good set of representative views, optimizing camera orbits to pass through good views and avoid bad views, and trackball controls that gently guide the viewer towards better views.

“…While positive spaces are seen as having clear borders, adults often describe negative spaces as having no definite shape at all, but rather as extending indefinitely behind the borders of the surfaces that enclose them (Rubin 1921;Baylis and Driver 1994;Driver and Baylis 1996;Hoffman and Singh 1997;Peterson 2003). Even though mental transformations do not hinder children's performance, as the results of the negative form and positive tower tasks tell us, the requirement that the shapes of positive and negative spaces be matched does.…”

The authors examined 14-to 26-month-old infants' understanding of the spatial relationships between objects and apertures in an object manipulation task. The task was to insert objects with various cross-sections (circular, square, rectangular, ellipsoid, and triangular) into fitting apertures. A successful solution required the infant to mentally rotate the object to be fit into the aperture and use that information to plan the action. The object was presented standing up in half of the trials; in the other half, it was lying down. The results showed that infants solved the problem consistently from age 22 months and that a successful solution was associated with appropriate preadjustments before the hand arrived with the block to the aperture. No sex differences were found.
