“…Moreover, as participants were instructed to maintain fixation on the cross throughout the experiment, foveal (i.e., color) vision was relatively less engaged by the stimuli. While our use of grayscale images differs from previous addiction-related AB studies, this experimental design is in keeping with the broader field of visual attention (e.g., O'Craven et al 1999; Corbetta et al 2005; Bar et al 2006), in which color images are more rarely employed unless the effects of color are specifically under investigation (e.g., Bonnel and Prinzmetal 1998; Reeves et al 2005). The maintenance of central fixation means that we were exploring covert attentional orienting, although covert effects are comparable to overt attention effects (Bradley et al 2000).…”

Rationale-While it is well documented that substance users exhibit attentional bias toward addiction-related stimuli, the exact mechanism remains unclear.Objectives-To differentiate between distinct aspects of attentional allocation in the smoking-cue attentional bias observed in smokers.Methods-Active smokers (AS) and non-smoking controls completed spatial cueing tasks with pairs of smoking and neutral pictorial cues to measure attentional capture, and an attentional blink task with either a smoking or neutral image appearing behind the first target (T1) to measure aspects of attention separate from capture. In addition, we tested groups of sports enthusiasts, and nonenthusiasts in corresponding tasks replacing smoking images with sports-related images to address the possibility that effects found in the smoking study were due simply to greater stimulus familiarity.Results-Smoking cues reflexively capture smokers' attention, as AS showed a greater bias toward smoking cues in short stimulus-onset asynchrony (SOA; the time between the onset of two stimuli) trials, but not in trials with a longer SOA. These effects represent a facilitation of responding to smoking-versus neutral-cued targets, and were absent in the sports control task. The attentional blink effects were similar in the smoking-and sports-cue experiments: the special T1 resulted in better detection of the second target for the smokers and sports enthusiasts.Conclusions-Stimulus familiarity may contribute to some aspects of attentional bias in regular nicotine users, but selective quick capture of attention by smoking cues may be nicotine-habit specific.

Neural Dynamics of Attentional Cross-Modality Control

Attentional networks that integrate many cortical and subcortical elements dynamically control mental processes to focus on specific events and make a decision. The resources of attentional processing are finite. Nevertheless, we often face situations in which it is necessary to simultaneously process several modalities, for example, to switch attention between players in a soccer field. Here we use a global brain mode description to build a model of attentional control dynamics. This model is based on sequential information processing stability conditions that are realized through nonsymmetric inhibition in cortical circuits. In particular, we analyze the dynamics of attentional switching and focus in the case of parallel processing of three interacting mental modalities. Using an excitatory-inhibitory network, we investigate how the bifurcations between different attentional control strategies depend on the stimuli and analyze the relationship between the time of attention focus and the strength of the stimuli. We discuss the interplay between attention and decision-making: in this context, a decision-making process is a controllable bifurcation of the attention strategy. We also suggest the dynamical evaluation of attentional resources in neural sequence processing.

The number of items in an array can be quickly and accurately estimated by dividing the array into subgroups, in a strategy termed “groupitizing.” When attempting to remember a telephone number, it is better to do so by dividing the number into several segments. Different forms of visual grouping can affect the accuracy of the enumeration of a large set of items. Previous studies have found that when groupitizing, enumeration accuracy is improved by grouping arrays using visual proximity and color similarity. Based on Gestalt theory, Palmer (1992) divided perceptual grouping into intrinsic (e.g., proximity, similarity) and extrinsic (e.g., connectedness, common region) principles. Studies have investigated groupitizing effects of intrinsic grouping. However, to the best of our knowledge, no previous study has explored groupitizing effects for extrinsic grouping cues. Therefore, this study explored whether extrinsic grouping cues differed from intrinsic grouping cues for groupitizing effects in numerosity estimation. The results showed that both extrinsic and intrinsic grouping cues improved enumeration accuracy. The extrinsic grouping cues were more accurate in terms of sensory precision of the numerosity estimation than were the intrinsic grouping cues.
