Abstract Attentional capture by salient distractors has been confirmed the occurrence of an N 2pc to distractor. To clarify some failures replicate this finding, we varied target predictability induce different search modes. In unpredictable condition, shape randomly from trial trial, favoring singleton detection mode. predictable remained same in a block trials, feature With targets, observed toward color distractor, confirming attentional there was no but distractor positivity ( P d),...
Cortical blindness refers to the loss of vision that occurs after destruction primary visual cortex. Although there is no sensory cortex and hence conscious vision, some cortically blind patients show amygdala activation in response facial or bodily expressions emotion. Here we investigated whether direction gaze could also be processed absence any functional A well-known patient with bilateral his subsequent cortical was an fMRI paradigm during which blocks faces were presented either their...
Abstract There has been a long-lasting debate about whether salient stimuli, such as uniquely colored objects, have the ability to automatically distract us. To resolve this debate, it suggested that stimuli do attract attention but they can be suppressed prevent distraction. Some research supporting viewpoint focused on newly discovered ERP component called distractor positivity (PD), which is thought measure an inhibitory attentional process. This collaborative review summarizes previous...
Seeber (2011) recently introduced a series of analytical cognitive load models, providing detailed illustration conjectured resource allocation during simultaneous interpreting. In this article, the authors set out to compare these models with data gathered in an experiment using task-evoked pupillary responses measure online interpreting when embedded single-sentence context and discourse context. Verb-final verb-initial constructions were analysed terms they cause inherently...
Top-down control of attention allows us to resist attentional capture by salient stimuli that are irrelevant our current goals. Recently, it was proposed suppression distractors contributes top-down biasing away from the distractor. With small search displays, may even result in reduced RTs on distractor-present trials. In support suppression, electrophysiological measures revealed a positivity between 200 and 300 msec contralateral distractor, which has been referred as distractor (PD). We...
Abstract We investigated the effects of task demands and individual differences on allocation attention. Using same stimuli, participants indicated orientation a line contained in shape singleton (identification task) or presence singletons (detection task). Shape identification elicited contralateral negativity ( N2pc ) whereas detection positivity Pd ). suggest that reduction attentional priority salient stimulus, reflected by , occurred more rapidly with less demanding task. Further,...
Search for a shape target is difficult when its similar to the of surrounding nontargets and easy it dissimilar. We asked whether interference from salient but irrelevant color singleton depended on search difficulty as manipulated by target-nontarget similarity. found that was strong in searches, occurrence an electrophysiological index attentional selectivity (the N2pc component) confirmed attention captured distractor. In contrast, distractor weak with PD component saliency signals were...
In a visual search task, sensory input is matched to representation of the target in working memory (VWM).This referred as attentional template.We investigated conditions that allow for more than single template.The template color targets was measured by means contingent capture paradigm.We found templates did not differ between with one and two memorized colors, suggesting dual allowed multiple templates.In same paradigm, we asked participants memorize distractor equal precision.Both were...
Visual working memory (VWM) is a core cognitive system enabling us to select and briefly store relevant visual information. We recently observed that more salient items were recalled precisely from VWM demonstrated these effects of salience resisted manipulations reward, probability, selection history. Here, we investigated whether how interacts with shifts attention induced by pre- retrocueing. Across four experiments, consistently found the on accuracy VWM. Spatial feature cues presented...
The N2pc is widely employed as an electrophysiological marker of attention allocation. This interpretation was largely driven by the observation elicited isolated relevant target object, which reported Experiment 2 in Eimer (1996). All subsequent refined interpretations had to take this crucial finding into account. Despite its central role for neurocognitive research, there have been no direct replications and only few conceptual seminal work. Within context #EEGManyLabs, international...
Optimal tuning of attention refers to shifts in goal-driven that increase the difference between representation target and nontarget features. Evidence for optimal comes from studies measuring memory and, a lesser degree, attentional selectivity. In one study on selectivity, cueing effects were found be greater cue colors deviating away color compared toward color, suggesting participants' search goal was optimally tuned. To address alternative accounts, we measured event-related potentials...
Abstract When observers are asked to localize the onset or offset position of a moving target, they typically make localization errors in direction movement. Similarly, when judge target that is presented alignment with flash, appears lead flash. These known as Fröhlich effect, representational momentum, and flash-lag respectively. This study compared size three mislocalization errors. In Experiment 1, flash appeared either simultaneously onset, mid-position, target. Observers then judged...
In speech perception, phonetic information can be acquired optically as well acoustically. The motor theory of perception holds that control structures are involved in the processing visible speech, whereas perceptual accounts do not make this assumption. Motor involvement was examined by showing participants response-irrelevant movies a mouth articulating /ba/ or /da/ and asking them to verbally respond with either same different syllable. letters "Ba" "Da" appeared on speaker's indicate...
The judged final position of a moving stimulus has been suggested to be shifted in the direction motion because mental extrapolation (representational momentum). However, perceptual explanation is possible: eyes overshoot target, and foveal bias, motion. To test this hypothesis, authors replicated previous studies, but instead having participants indicate where target vanished, probed participants' focus by presenting probe stimuli close vanishing point. Identification probes was more...
In the Simon effect, participants make a left or right keypress in response to nonspatial attribute (e.g., color) that is presented on right. Reaction times (RTs) increase when activated by irrelevant stimulus location and retrieved instruction are conflict. The authors measured RTs movement parameters (MPs) of pointing responses typical task. Their results show trajectories veer toward imperative stimulus. This bias decreased as increased. suggest time course trajectory deviations reflects...
The current study investigated whether capture of the eyes by a salient onset distractor and disengagement from that are driven same or different underlying control modes. A variant classic oculomotor task was used. Observers had to make saccade only gray circle among red background circles. On some trials, green (novel color), (placeholder color) (target square presented with sudden onset. Results showed when participants reacted fast, primarily bottom-up pop-out: both types distractors...
Previous research has established that interference from irrelevant-but-salient color distractors occurs when observers search for variable-shape singletons among uniform shapes (singleton detection), but not they look a specific shape mixed (feature search). In the current study, we replicated this finding, and additionally, introduced random variation of color. Instead always presenting same target distractor colors, colors were swapped randomly trial to trial. With variation, was...
