“…Preattentive mechanisms that scan the environment to detect faces automatically (Elder, Prince, Hou, Sizintsev, & Olevskiy, 2007;Lewis & Edmonds, 2003;'t Hart, Abresch, & Einhäuser, 2011) may exist to compensate for the difficulty in distinguishing subtle facial characteristics at periphery or in unattended central locations (Devue, Laloyaux, et al, 2009). This could be achieved through magnocellular channels that extract low spatial frequencies that are used for holistic processing (Awasthi, Friedman, & Williams, 2011a, 2011bCalvo, Beltrán, & Fernández-Martín, 2014;Girard & Koenig-Robert, 2011;Goffaux, Hault, Michel, Vuong, & Rossion, 2005;Johnson, 2005;Taubert, Apthorp, AagtenMurphy, & Alais, 2011). Holistic processing can be demonstrated as fast as 50 ms after exposure to a face (Richler, Mack, Gauthier, & Palmeri, 2009;Taubert et al, 2011) and is indexed by an early face-specific P100 ERP component (Nakashima et al, 2008).…”

“…By bringing the face into foveal vision, this orienting reflex could facilitate the extraction of further information conveyed by medium and high spatial frequency information (Awasthi et al, 2011a(Awasthi et al, , 2011bDeruelle & Fagot, 2005;Gao & Maurer, 2011; see also Underwood, Templeman, Lamming, & Foulsham, 2008, for a similar argument with objects within complex scenes) to complement the partial information gathered at periphery via low spatial frequencies, for example, about familiarity (Smith et al, 2016) or facial expression (Vuilleumier et al, 2003). Fixating a face enables finer facial discrimination (e.g., wrinkles associated with facial expressions; see Johnson, 2005) and may help, nay be necessary, to reach a definite decision about the meaning of the face in terms of facial expression, identity, gender, race, or intentions.…”

We compared the ability of angry and neutral faces to drive oculomotor behaviour as a test of the widespread claim that emotional information is automatically prioritized when competing for attention. Participants were required to make a saccade to a colour singleton; photos of angry or neutral faces appeared amongst other objects within the array, and were completely irrelevant for the task. Eye-tracking measures indicate that faces drive oculomotor behaviour in a bottom-up fashion; however, angry faces are no more likely to capture the eyes than neutral faces are. Saccade latencies suggest that capture occurrs via reflexive saccades and that the outcome of competition between salient items (colour singletons and faces) may be subject to fluctuations in attentional control. Indeed, although angry and neutral faces captured the eyes reflexively on a portion of trials, participants successfully maintained goal-relevant oculomotor behaviour on a majority of trials. We outline potential cognitive and brain mechanisms underlying oculomotor capture by faces.

“…Gaze aversion has been associated with cognitive load as a management strategy (Doherty-Sneddon et al, 2012), children with ASD showing elevated levels of gaze aversion while listening to questions, but not while making their responses. Where direct psychophysical measurement of face processing in normal adults has been made, peripherally presented low spatial frequency information has been shown to enable efficient processing of faces (Awasthi et al, 2011). …”

Peripheral global neglect in high vs. low autistic tendency

In addition to its core social deficits, autism is characterized by altered visual perception, with a preference for local percept in those high in autistic tendency. Here, the balance of global vs. local percepts for the perceptually rivalrous diamond illusion was assessed between groups scoring high and low on the Autism Spectrum Quotient (AQ). The global percept of a diamond shape oscillating horizontally behind three occluders can as easily be interpreted as the local percept of four line elements, each moving vertically. Increasing the luminance contrast of the occluders with respect to background resulted in an increase of initial global percept in both groups, with no difference in sensitivity between groups. Presenting the target further into the periphery resulted in a marked increase in the percentage of global perception with visual field eccentricity. However, while the performance for centrally presented diamond targets was not different between AQ groups, the peripheral global performance of the High AQ group was significantly reduced compared with the Low AQ group. On the basis of other imaging studies, this peripheral but not foveal global perceptual neglect may indicate an abnormal interaction between striate cortex and the Lateral Occipital Complex (LOC), or to differences in the deployment of attention between the two groups.
