The relations between temporal and social perceptual biases: Evidence from perceptual matching

We report a new “now-bias” effect on simple perceptual matching between shapes and labels and examined the relation between this now-bias effect and the self-bias previously established with this task (Sui, He, & Humphreys, Journal of Experimental Psychology: Human Perception and Performance, 38, 1105–1117, 2012). The perceptual biases favoring present-relevant and self-relevant...

Multisensory enhancement elicited by unconscious visual stimuli

The merging of information from different senses (i.e., multisensory integration) can facilitate information processing. Processing enhancements have been observed with signals that are irrelevant to the task at hand, and with cues that are non-predictive. Such findings are consistent with the notion that multiple sensory signals are sometimes integrated automatically...

In-group biases and oculomotor responses: beyond simple approach motivation

An in-group bias describes an individual’s bias towards a group that they belong to. Previous studies suggest that in-group bias facilitates approach motor responses, but disrupts avoidance ones. Such motor biases are shown to be more robust when the out-group is threatening. We investigated whether, under controlled visual familiarity and complexity, in-group biases still...

Aging enhances cognitive biases to friends but not the self

We measured changes in self and friend biases in perceptual matching in young and older participants. Participants learned associations between neutral geometric shapes and three personal labels (You, Friend, or Stranger), representing themselves, their named best friend, and a stranger not corresponding to anyone they knew. They then responded whether the shapes and labels...

Exploring the quiet eye in archery using field- and laboratory-based tasks

The ‘quiet eye’ (QE)—a period of extended gaze fixation on a target—has been reported in many tasks that require accurate aiming. Longer quiet eye durations (QEDs) are reported in experts compared to non-experts and on successful versus less successful trials. The QE has been extensively studied in the field; however, the cognitive mechanisms underlying the QE are not yet fully...

Stored color–form knowledge modulates perceptual sensitivity in search

We used signal detection analysis to examine the effects of stored color–form knowledge on visual search. Across four experiments, we showed robust effects of stored color–form knowledge on perceptual sensitivity, whereas the effects on response criteria varied. The effects on perceptual sensitivity were stronger when multiple items were present and when the color fell on the...

The differential outcomes procedure can overcome self-bias in perceptual matching

There are biases in perceptual matching between shapes and labels referring to familiar others, compared with when the labels refer to unfamiliar people. We assessed whether these biases could be affected by differential feedback (using the differential outcomes procedure [DOP]) compared with when feedback is provided using a nondifferential outcomes procedure (NOP). Participants...

In-group modulation of perceptual matching

We report a novel effect of in-group bias on a task requiring simple perceptual matching of stimuli. Football fans were instructed to associate the badges of their favorite football team (in-group), a rival team (out-group), and neutral teams with simple geometric shapes. Responses to matching in-group stimuli were more efficient, and discriminability was enhanced, as compared to...

Exploring social cognition in patients with apathy following acquired brain damage

Background Research on cognition in apathy has largely focused on executive functions. To the best of our knowledge, no studies have investigated the relationship between apathy symptoms and processes involved in social cognition. Apathy symptoms include attenuated emotional behaviour, low social engagement and social withdrawal, all of which may be linked to underlying socio...

Visual marking across eye blinks

Visual search for a conjunction target can be made efficient by presenting one initial set of distractors as a preview, prior to the onset of the other items in the search display Watson & Humphreys (Psychological Review 104:90–122, 1997). However, this “preview advantage” is lost if the initial items are offset for a brief period before onsetting again with the search display...

Apathy symptoms modulate motivational decision making on the Iowa gambling task

Background The present study represents an initial attempt to assess the role of apathy in motivated decision making on the Iowa Gambling Task. Clinical descriptions of patients with apathy highlight deficits in the cognitive, emotional and behavioural aspects of goal directed activity, yet standard neurocognitive tests of these measures fail to demonstrate reliable sensitivity...

Age-related differences in selection by visual saliency

We examined the ability of older adults to select local and global stimuli varying in perceptual saliency—a task requiring nonspatial visual selection. Participants were asked to identify in separate blocks a target at either the global or the local level of a hierarchical stimulus, while the saliency of each level was varied (across different conditions, either the local or the...

Action relations facilitate the identification of briefly-presented objects

Dynamic cultural modulation of neural responses to one's own and friend's faces

Long-term cultural experiences influence neural response to one's own and friend's faces. The present study investigated whether an individual's culturally specific pattern of neural activity to faces can be modulated by temporary access to other cultural frameworks using a self-construal priming paradigm. Event-related potentials were recorded from British and Chinese adults...

Spreading suppression and the guidance of search by movement: Evidence from negative color carry-over effects

A growing number of studies have shown that significant impairments to search and selection can occur if the target item carries a feature of the irrelevant distractors currently being ignored Braithwaite, Humphreys, and Hodsoll (Journal of Experimental Psychology: Human Perception and Performance, 29, 758–778, 2003). However, these effects have been documented only when search...
