This special issue of Visual Cognition features empirical and theoretical contributions by leading research scholars in the field. The volume begins with a general introduction and an authoritative review of work on spatial attention in the flankers task. Next, a series of empirical articles reports important new findings on visual selection by spatial location. A second section contrasts by presenting recent empirical findings on visual selection by other criteria. Finally, four articles present major theoretical statements on aspects of visual attention. As a whole, the issue forms a substantial contribution to the literature on visual selective attention.

Visual attention is involved in many everyday tasks, such as finding one’s shoes, driving, or looking for a face in a crowd. Often attention must be allocated or split onto more than one location. Yet how does the visual system accomplish this, and what cost does it have in terms of performance in visual tasks? This dissertation reports the results of an investigation of the claim that attention could be allocated to two or more non-contiguous locations simultaneously. This study uses a technique, which to the best of my knowledge, has not been used by other investigators studying the splitting of attention. The stimulus used in the current thesis consisted of four possible cue locations, with each potential location located in 45 degree increments (45, 135, 225, 315 degrees) at the same eccentricity. Experiment 1 replicated the results of previous attention studies, but using the new cueing paradigm. The results showed that the spotlight of attention could change location when multiple potential locations are present. The advantage of the new paradigm is the possibility of cueing different locations within and between visual hemifields. This was explored in Experiments 2 and 3, to examine the role of hemispheric asymmetries in the debate over multifocal attention. Specifically, two locations were cued in Experiment 2, and Experiment 3 examined the differences of splitting the attentional beam within and across hemifields. Finally, Experiment 4 investigated the effect of cueing all four locations at the same time. The results from the current thesis confirm that observers can allocate attention to two or more simultaneous locations, without observing any attentional enhancement coming from the in-between cued locations. However, these results stemmed from attending to two locations across hemifields. The present thesis provides more evidence in support of the ability to split attention, and describes the impact that multifocal attention plays in visual perception.

This thesis project is a method of measuring the modulation transfer function of spatial visual attention. When the assumptions of this method of measuring attention are satisfied, the method enables one to calculate, for any attentional demand whatsoever, the extent to which an observer could mould his or her distribution of spatial attention to meet the demand. This research is being reported at ARVO, 1997, and a preliminary report is attached herewith.

Attention: Theory and Practice provides a balance between a readable overview of attention and an emphasis on how theories and paradigms for the study of attention have developed. The book highlights the important issues and major findings while giving sufficient details of experimental studies, models, and theories so that results and conclusions are easy to follow and evaluate. Rather than brushing over tricky technical details, the authors explain them clearly, giving readers the benefit of understanding the motivation for and techniques of the experiments in order to allow readers to think through results, models, and theories for themselves. Attention is an accessible text for advanced undergraduate and graduate students in psychology, as well as an important resource for researchers and practitioners interested in gaining an overview of the field of attention.

In many visual selection experiments, Ss view displays of colored letters and numbers. They are instructed to attend to some stimulus dimension (e.g., row location, color, class) and are cued to report the items indicated by one value (e.g., top row, red color) on that dimension. Accuracy is always highest for row report. Since the items cued by row are spatially connected and easily coded for memory, and those cued by color or class spatially scattered and difficult to code, it cannot be concluded that row selection is more efficient than, say, color selection. In these experiments, selection criterion is held constant, and the spatial arrangement of the targets is varied. In Exp. I, Ss reported the identities of the 5 red letters appearing in a 5 x 5 matrix. Four types of target arrangements were tested. Four backgrounds, varying in degree of confusability with the targets, were combined factorially with the four target patterns. The effects of pattern and background and their interaction were highly significant. It is suggested that spatial arrangement per se is not crucial; rather the target pattern serves to control the degree of background interference. Experiments II and III were detection analogs of the Letters background similarity condition of Exp. I. The Ss had to report whether an A or a T appeared among the red letters. The results for the pattern types were similar, indicating that there are spatial constraints on visual processing at a level low enough to be tapped in a detection task. (Author).

Humans can focus their attention narrowly (e.g., to read this text) or broadly (e.g., to determine which way a large crowd of people are moving). This Element comprehensively considers attentional breadth. Section 1 introduces the concept of attentional breadth, while Section 2 considers measures of attentional breadth. In particular, this section provides a critical discussion of the types of psychometric evidence which should be sought to establish the validity of measures of attentional breadth and reviews the available evidence through this lens. Section 3 considers the visual task performance consequences of attentional breadth, including prescribing several key methodological criteria that studies that manipulate attentional breadth need to meet, as well as a discussion of relevant theories and avenues for future theoretical development. Section 4 discusses the utility of the exogenous-endogenous distinction from covert shifts of attention for understanding the performance consequences of attentional breadth. Finally, Section 5 provides concluding remarks.
