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...
Few studies have examined whether semantic relatedness between objects can influence object grouping, thereby optimizing the efficiency of visual working memory (WM). Moreover, these largely used real-world grayscale objects. Here, we sought to determine and how sharing semantics colors would benefit WM. Participants viewed six to-be-remembered objects, arranged as one semantically related and/or perceptually similar pair plus four singletons, or singletons. Perceptually pairs shared color,...
Age-related differences in visual search have been extensively studied using simple item arrays, showing an attentional decline. Little is known about how aging affects guidance during more complex scenes. To study this issue, we analyzed eye-movement behavior realistic scene search. We examined age-related top-down guidance, manipulating target template specificity (picture vs. word cue) and target-scene semantic consistency (consistent inconsistent), bottom-up perceptual salience (high...
Visual search is a crucial task in daily life, but Alzheimer's disease (AD) it has usually been investigated using simple arrays. Here, we used scenes depicting real environments and studied the time course of attentional guidance.
Visual search is a crucial, everyday activity that declines with ageing. Here, referring to the environmental support account, we hypothesised semantic contextual associations between target and neighbouring objects (e.g., teacup near tea bag spoon), acting as external cues, may counteract this decline. Moreover, when searching for target, viewers encode information about co-present distractor objects, by simply looking at them. In life, where often several targets within same environment,...
Elderly people and, especially, patients with Alzheimer's disease (AD) show impaired performance in visual search. This seems to arise from inefficient strategies, an increased number of eye fixations and longer fixation durations. As many activities daily living require efficient search objects within complex environments, deficits AD may have a key role reducing their functional autonomy. However, while previous studies examined patients' simple object arrays, little is know about...
Consistent semantic relations among objects (e.g., a toothbrush near toothpaste) have been found to boost visual short-term memory. Perceptual similarity, particularly shared color, also benefits memory for single-feature objects. This color-sharing bonus can be explained by compression process that compacts redundant information gain storage space. Here we aimed investigate whether could offer general account of both semantic- and bonuses in If so, then color- semantic-sharing effects...
Visual search performance can be facilitated by incidentally learned associations between contextual regularities and target locations within repeated displays, effect known as cueing (CC). Robust CC has been found in numerous studies, but the exact mechanisms underlying are still not well understood. Here, we investigated factors that best account for differential effects across stimulus configurations. Twenty-three participants searched a T-shape among L-shape distractors reported target’s...
