The length of a piece of string
Determination of the magnitude or size of objects is crucial in many activities of daily living. Here we provide psychophysical evidence across multiple experiments that judgements for accumulated length of fragmented lines are non-veridical, with a larger number of fragments leading to a larger reduction in perceived size. The reported reduction in the size of fragmented stimuli is not a result of stimulus bias or frequency of observations and r…
More or less of me and you
Self-relevance exerts a powerful influence on information processing. Compared to material associated with other people, personally meaningful stimuli are prioritized during decision-making. Further exploring the character of this effect, here we considered the extent to which stimulus enhancement is impacted by the frequency of self-relevant versus friend-relevant material. In a matching task, participants reported whether shape-label stimulus p…
Self-relevance enhances evidence gathering during decision-making
The visual influence of ostracism
Reflecting the fundamental human need to establish and maintain positive connections with others, it has been suggested that an Ostracism Detection System is sensitized to targets by which one has been ostracized. Evidence supporting the operation of this system has yet to be provided, however. Accordingly, using binocular rivalry to explore attentional processing, here, we considered the extent to which targets previously associated with ostraci…
Saccadic latency is modulated by emotional content of spatially filtered face stimuli
Models of attention and emotion assign a special status to the processing of threat. While evidence for threat-related attentional bias in highly anxious individuals is robust, effects in the normal population are mixed. An important explanation for the absence of threat-related attentional bias in nonanxious individuals may relate to the spatial frequency components of stimuli. Here we report behavioral data from two experiments examining the re…
Attentional bias to brief threat-related faces revealed by saccadic eye movements
According to theories of emotion and attention, we are predisposed to orient rapidly toward threat. However, previous examination of attentional cueing by threat showed no enhanced capture at brief durations, a finding that may be related to the sensitivity of the manual response measure used. Here we investigated the time course of orienting attention toward fearful faces in the exogenous cueing task. Cue duration (20 ms or 100 ms) and response …
Awareness of faces is modulated by their emotional meaning
A central question in perception is how stimuli are selected for access to awareness. This study investigated the impact of emotional meaning on detection of faces using the attention blink paradigm. Experiment 1 showed that fearful faces were detected more frequently than neutral faces, and Experiment 2 revealed preferential detection of fearful faces compared with happy faces. To rule out image artifacts as a cause for these results, Experiment…
