“…1). This task is considered to demand a high degree of visual selective attention, decision making, and motor control (Davis and Palmer 2004;Ettenhofer et al 2016;Schill et al 2020). Neural sensitivity to semantic processing was assessed using an functional magnetic resonance imaging (fMRI) response adaptation paradigm (also known as repetition suppression) (Grill-Spector 2006;Garrido et al 2009;Larsson and Smith 2012).…”

Incidental Verbal Semantic Processing Recruits the Fronto-temporal Semantic Control Network

The frontoparietal semantic network, encompassing the inferior frontal gyrus and the posterior middle temporal cortex, is considered to be involved in semantic control processes. The explicit versus implicit nature of these control processes remains however poorly understood. The present study examined this question by assessing regional brain responses to the semantic attributes of an unattended stream of auditory words while participants’ top–down attentional control processes were absorbed by a demanding visual search task. Response selectivity to semantic aspects of verbal stimuli was assessed via a functional magnetic resonance imaging response adaptation paradigm. We observed that implicit semantic processing of an unattended verbal stream recruited not only unimodal and amodal cortices in posterior supporting semantic knowledge areas, but also inferior frontal and posterior middle temporal areas considered to be part of the semantic control network. These results indicate that frontotemporal semantic networks support incidental semantic (control) processes.

“…Theoretically, what constitutes a local element, part or geon is a topic of continued debate. The definition may be a derivative of conjunctions and boundaries or relate to axis-based primitives (Schill et al, 2020 ; Wolfe, 2020 ). Although our account contradicts some “single process” approaches to object recognition (e.g., the parts-based “recognition by components” view of Biederman et al, 1999 ), it does concur with a hybrid account in which global shape representations are computed “on the fly” independently of feature coding (Stankiewicz et al, 1998 ).…”

“…Neuropsychological evidence also indicates that, in the absence of attention, recognition may be view-specific rather than view-invariant (Lawson et al, 1994 ; Tarr et al, 1998 ; Ullman, 1998 ; Schill et al, 2020 ). Vernier and Humphreys ( 2006 ) examined patients with unilateral neglect after damage to their parietal cortex who were poor at attending to stimuli in their contra-lesional field.…”

Evidence is presented for intermediate, wholistic visual representations of objects and non-objects that are computed online and independent of visual attention. Short-term visual priming was examined between visually similar shapes, with targets either falling at the (valid) location cued by primes or at another (invalid) location. Object decision latencies were facilitated when the overall shapes of the stimuli were similar irrespective of whether the location of the prime was valid or invalid, with the effects being equally large for object and non-object targets. In addition, the effects were based on the overall outlines of the stimuli and low spatial frequency components, not on local parts. In conclusion, wholistic shape representations based on outline form, are rapidly computed online during object recognition. Moreover, activation of common wholistic shape representations prime the processing of subsequent objects and non-objects irrespective of whether they appear at attended or unattended locations. Rapid derivation of wholistic form provides a key intermediate stage of object recognition.

“…Feature integration theory has been supported by a plethora of research (see Quinlan, 2003;Humphreys, 2016 for reviews), and while it has been partially subsumed into more comprehensive theories (e.g., Duncan and Humphreys, 1989;Desimone and Duncan, 1995), it has undeniably made a significant contribution to our understanding of visual attention. While early work using this model was largely restricted to analysis of basic features such as colour and shape, subsequent work has included dynamic features such as direction of motion (Dick et al, 1987;Thornton and Zdravković, 2020) and axis of rotation (Schill et al, 2020). Recently, feature integration theory has been particularly useful in the development of a concrete operationalisation of perceptual load.…”

Visual Search in 3D: Effects of Monoscopic and Stereoscopic Cues to Depth on the Validity of Feature Integration Theory and Perceptual Load Theory

Previous research has successfully used feature integration theory to operationalise the predictions of Perceptual Load Theory, while simultaneously testing the predictions of both models. Building on this work, we test the extent to which these models hold up in a 3D world. In two experiments, participants responded to a target stimulus within an array of shapes whose apparent depth was manipulated using a combination of monoscopic and stereoscopic cues. The search task was designed to test the predictions of (a) feature integration theory, as the target was identified by a single feature or a conjunction of features and embedded in search arrays of varying size, and (b) perceptual load theory, as the task included congruent and incongruent distractors presented alongside search tasks imposing high or low perceptual load. Findings from both experiments upheld the predictions of feature integration theory, regardless of 2D/3D condition. Longer search times in conditions with a combination of monoscopic and stereoscopic depth cues suggests that binding features into three-dimensional objects requires greater attentional effort. This additional effort should have implications for perceptual load theory, yet our findings did not uphold its predictions; the effect of incongruent distractors did not differ between conjunction search trials (conceptualised as high perceptual load) and feature search trials (low perceptual load). Individual differences in susceptibility to the effects of perceptual load were evident and likely explain the absence of load effects. Overall, our findings suggest that feature integration theory may be useful for predicting attentional performance in a 3D world.
