“…Therefore, not only did the shape inducer used by Goodhew et al (2016) and the motion inducer used in the current study differ in their attentional requirements, they also differed in their visual requirements, such that they were likely processed by two different areas of the visual system. Consequently, there are two possible explanations for the discrepancy between the results obtained in Experiment 1 and those obtained by Goodhew et al (2017Goodhew et al ( , 2016. Firstly, the attentional requirements between the shape inducer and the motion inducer differed.…”

“…While only a handful of studies have explored the influence of attentional scaling on temporal processing, they have found conflicting results (e.g. Goodhew, Lawrence, & Edwards, 2017;Goodhew, Shen, & Edwards, 2016;Mounts & Edwards, 2017;Poggel, Treutwein, Calmanti, & Strasburger, 2006).…”

“…According to this model, the primary role of attentional scaling is to increase the spatial resolving power of the visual system, and thus, attentional scaling only acts on the visual channel predominantly responsible for this capacity, i.e. parvocellular neurons (Goodhew et al, 2017(Goodhew et al, , 2016.…”

Originally, the zoom lens model of attention scaling proposed that narrowing attention to a small area of the visual field improves visual perception (Eriksen & James, 1986). A large body of empirical evidence supports this model, showing that narrow attention enhances performance in spatial acuity tasks. Despite this, the zoom lens model does not explicitly consider how attention scaling influences different elements of vision, for example, temporal processing. More recent models of attention scaling suggests that attentional scaling has different effects on spatial and temporal acuity (Goodhew et al., 2017, 2016). However, the evidence to date supporting these models has had one major pitfall: different sized unfilled shapes are presented in an attempt to focus attention in or spread it out broadly. This method is problematic because participants may not spread their attention across the entire region defined by unfilled shapes, instead, attending to only the annulus region of the shape. To address this, we developed a new method to manipulate attention, one which requires the pooling of information across the entire stimulus, not just around the outer border. We then tested the influence of attention scaling on perception using spatial and temporal gap tasks. Across two experiments, we found that sustaining a narrow attention scale improved both spatial and temporal acuity. These findings challenge recent research suggesting that attention scaling has differential impacts on spatial and temporal processing, instead supporting the zoom lens model, proposed over 30 years ago.

“…As we have also pointed out on numerous occasions (Skottun, 2000(Skottun, , 2013(Skottun, , 2014(Skottun, , 2016Skottun & Skoyles, 2007) such differences do exist. Thus, both claims by Goodhew et al (2017) are incorrect. What we have done is to point out difficulties using suprathreshold stimuli (i.e., at contrast levels above threshold) to differentiate contributions from the magno-and parvocellular systems to psychophysical tasks.…”

Different attentional focus sizes modulate the size–eccentricity effect

et al. 2022

The size-eccentricity effect is a perceptual distortion phenomenon in which a peripherally located object is perceived to be smaller than a centrally located object. Although the increase in apparent object size caused by attention has been documented, little is known about the effect of different sizes of attentional focus on object appearance. The present study investigated how different sizes of attentional focus affect the size-eccentricity effect using a spatial pre-cueing paradigm. Additionally, we examined the influence of different task types on size perception. A peripheral object following a small attentional focus appeared larger, without observation of the size-eccentricity effect. In contrast, a peripheral object appeared smaller following a large attentional focus in both larger and smaller judgement tasks. These results suggest that the relative size of the attentional focus has opposite effects on the perception of object size, independent of task type. Furthermore, in addition to the structural properties of the retina and the locus of attention, the size of attentional focus determines the extent to which an object appears smaller in the periphery. The present study complements the attentional attraction field model of the size and density of population receptive fields in V1 and further explains how the effect of attention is restricted by retinal structure.
