There is substantial debate over whether visual working memory (VWM) and attention constitute a single system for the selection of task-relevant perceptual information or they are distinct systems that can be dissociated when their representational demands diverge. In present study, we focused on relationship between encoding objects into VWM. Participants performed color change-detection task. During retention interval, secondary object, irrelevant to task, was presented. were instructed...
Abstract The life script account of the reminiscence bump in autobiographical memories suggests that cultural expectations about nature and timing transitional events lead to bump. empirical evidence for scripts is limited. We tested generality by looking at effects culture, gender cohorts. Turkish participants were asked (a) list seven most important a newborn or an elderly would experience during his/her lifetime (b) estimate prevalence, importance, age‐at‐event emotional valence each...
NMR spectroscopy is increasingly used in combination with multivariate analysis applications. Especially the of food products and study natural processes it has proved its usefulness. The samples these evaluations are however, often difficult to control. 'Positional' shifts peaks due differences pH other physico-chemical interactions quite common. A reduction resolution spectra generally sufficient correct for effects. This approach is, not possible if fine structure data important analysis....
Recent evidence has suggested that relatively precise information about the location and visual form of a saccade target object is retained across saccade. However, this appears to be available for report only when removed briefly, so display blank eyes land. We hypothesized availability dependent on whether post-saccade mapped same representation established presaccade target. If so, then features overwrite features, process mediated updating in which masking governed by continuity. In two...
The contribution of surface feature continuity to object-based inhibition return (IOR) was tested in three experiments. Participants executed a saccade previously fixated or unfixated coloured disk after the object had moved new location. Object-based IOR observed as lengthened latency object. consistency (colour) and spatiotemporal information manipulated examine used define persisting objects which is assigned. If two traded colours during motion, reliably reduced (Experiment 2),...
Visual working memory (VWM) is an essential aspect of cognitive functioning that becomes compromised in older adults. A canonical probe VWM the change detection task which participants compare a visually presented stimulus with items being maintained VWM. Older adults show decreased ability to detect changes between and contents compared younger Previously, we used dynamic neural field (DNF) model explore connectivity can explain this pattern decline performance. These simulations suggest...
Understanding the dynamics of selective attention has been a central research goal in cognitive sciences. One account proposes that is unitary and increases selectivity continuously over time. An alternative switches from low to high state at discrete point time when distinct mechanism engaged. Despite posing fundamentally different theoretical perspectives on attention, both accounts have successfully explained outcome-based data, such as reaction Here, we used mouse-tracking, which...
With each saccade, visual information is disrupted, and the system tasked with establishing object correspondence between presaccadic postsaccadic representations of saccade target. There substantial evidence that consults spatiotemporal continuity when determining across saccades. The for surface feature continuity, however, mixed. Surface features are integral to target object's identity (e.g., shape contrast polarity) informative but may only imply state orientation) ignored. present...
How are visual sensory representations that acquired peripherally from a saccade target related to generated foveally after the saccade? We tested hypothesis that, when two perceived belong same object, post-saccadic value tends overwrite pre-saccadic value. Participants executed colored which sometimes changed during by ±15°, 30°, or 45° in color space. They were post-cued report either continuous procedure. Substantial overwriting of was observed. Moreover, introduction brief blank...
During everyday scene viewing, the human visual system faces many challenges. The most frequent disruption of input occurs during saccadic eye movements. Every time we execute a saccade, perceptual is disrupted by both suppression and shifts objects’ retinal locations. Despite these changes, quite efficient at representing stable world (i.e. establishing stability). We have previously proposed that transsaccadic integration depends on an object-mediated updating (OMU) process (Tas, Moore, &...

The present study used pupillometry to assess listening effort in normal-hearing adults during a speech perception task. Early research on relied self-report or subjective measures effortful listening, while more recent studies employ objective better quantify various conditions. Further, audiological evaluations reveal that cochlear implant (CI) recipients experience greater difficulty understanding due the spectrally-degraded quality of input. To test this, Defenderfer et al. (2017)...
Saccadic adaptation is the process by which visual system adjusts saccadic amplitude when faced with consistent landing errors displaced saccade targets. The present study investigated perceptual consequences of adaptation. Previous work showed that not only changes position but also modifies presaccadic covert shift attention (Doré-Mazars & Collins, 2005; Collins Doré-Mazars, 2006). Specifically, after shifts to adapted spatial location, rather than target location. Recently, Van der...
Previous research has shown that motor movements, such as pointing or saccades, influence the weighting of action-relevant object representations within visual working memory (VWM). We previously found evidence manual movements results in inhibition action-irrelevant VWM while they enhance (Mugno et al., VSS 2022). In present study, we investigated whether saccades can also result similar items. instructed participants to remember two color stimuli presented an array eight circles. At end...
