Samenvatting This book is a succinct introduction to the orienting of attention. Richard Wright and Lawrence Ward describe the covert orienting literature clearly and concisely, illustrating it with numerous high-quality images, specifically designed to make the challenging theoretical concepts very accessible.

The book begins with an historical introduction that provides a great deal of information about orienting, much of which will be new even to seasoned researchers. Wright and Ward then systematically describe the development of various experimental paradigms that have been devised to study covert orienting, and the theoretical issues raised by this research. One trend that they analyze in detail is the progression from relatively simple models of spatial attention attention spotlight and zoom lens models to an integrative computational framework based on a concept called the ''activity distribution.

In the Epilogue they offer a concise summary of the book, and develop preliminary frameworks for understanding the relationship between spatial attention and orienting in response to social cues social cognitive neuroscience and for describing the evolution of covert orienting. Orienting of Attention provides a systematic survey that is ideal for those looking for an accessible introduction to the field and also for students and researchers who want a state-of the-art overview.

It represents an impressive, nearly encyclopedic survey of attention shifts, their relation to the underlying brain anatomy and to the eye movement system. This book also documents the important effort to model attention shifts. Peter Squire, Pamela Greenwood, Raja Parasuraman; Involuntary but not voluntary orienting modulates the splitting of attention.

Journal of Vision ;9 8 Background: The focus of attention need not be unitary but can be split between noncontiguous locations. However, in the absence of a suppressive mechanism triggered by external noise e. This need for a suppressive mechanism to induce splitting suggests that involuntary but not voluntary orienting of attention may modulate the splitting of attention.

Based on these findings, we predicted that when orienting was voluntary, attention would be split via a suppressive mechanism but when orienting was involuntary, attention would split or scaled depending on task demands for suppression or enhancement. The hypothesis was tested in two experiments that manipulated the orienting and distribution the scale of the attentional focus of attention and the level of external noise.

Method: A cued search task precued location of a target digit in a search array of distractor letters. Conditions were: orienting type involuntary and voluntary ; distribution type constricted, scaled, or split ; external noise high and low. External noise was manipulated by the distance between stimuli i. All cues were valid in predicting target location.
