Abstract

Visual processing largely relies on the identification of the hierarchical levels of visual stimuli, from the largest global level (e.g., large circle) to the most local elements (e.g., small squares). People are faster at detecting information at the global level, relative to the local level and incongruent global information usually slows down the detection at the local level. We aimed to investigate for the first time the brain mechanisms behind local and global prosessing during a visual search task of compound hierarchical stimuli in early and late adulthood.

Abstract

International audience; Visual distractions as a key factor during visual search Because of our limited attentional capacity (Desimone & Duncan, 1995), searching for relevant information frequently induces attentional competition between relevant and distracting information. Handling with visual distractors plays a key role during effective visual search and depends, at least in part, on the target and distractors attributes (e.g., Duncan & Humphreys, 1989). Ignoring visual distractors is critical to ensure optimal working memory performance through lifespan (e.g., Zanto & Gazzaley, 2009).

Abstract

International audience; In healthy controls (HCs), the visuospatial attentional network consists of fronto-parietal bundles distributed across both hemispheres. Theanatomical organization of this network remains unexplored in patients with schizophrenia (SZPs). The aim of the present study was to determinate the white matter integrity (WM) and the volume of visuospatial attentional pathways in the right and left hemispheres (RH and LH), as well as their structural asymmetry in SZPs and HCs, using diffusion tensor imaging (DTI)-based tractography. We hypothesized that SZPs would have WM pathway alterations and reduced rightward structural asymmetry.

Abstract

Abstract

International audience; INTRODUCTIONRecent models of visual perception suggested that scene recognition is processed in terms of spatial frequencies: in adults, low spatial frequencies (LSF) rapidly reach high-order cortical areas to allow initial scene recognition and high spatial frequencies (HSF) subsequently carry fine details analysis (Kauffmann, 2014). Paradigms using compound stimuli (large global forms, supposed to convey HSF, composed of arrangements of small local forms, supposed to convey HSF) had indicated an evolution from a local (HSF) preference in young children (Poirel, 2008) evolving toward a global (LSF) preference, from 6 years of age until the end of adolescence (Mondloch, 2003). The present MRI study investigated for the first time the relationship between cortical thickness and behavioral performances to LSF/HSF during this childhood transitional period. METHODSSixteen children (M=10 years, SD=7 months, 6 boys) and 16 adults (M=30 years, SD=5 years, 9 boys) were presented with 80 pictures of natural scenes filtered either in LSF or in HSF (Fig1). Each scene was presented during 40ms and participants had to indicate as rapidly as possible whether the scene was outdoor or indoor. Reaction times were recorded. Participants were scanned with a 3-Tesla MRI scanner (T1-weighted, FOV: 256mm; slice thickness: 1.33 mm; 128 slices; matrix size 192×192 voxels; 5min7s duration). Mean cortical thickness values were extracted with Freesurfer software using the Destrieux Atlas (2010). For each group, regression analyses were carried to investigate the relationship between cortical thickness and LSF/HSF reaction times (RTs). All results reported are statistically significant at 0.05.RESULTSBehavioral data indicated that adults showed faster RTs than children (495±12ms and 867±34ms respectively, p

Abstract

International audience; Recent models of visual perception suggested that scene recognition is processed in terms of spatial frequencies: low spatial frequencies (LSF) rapidly reach high-order cortical areas to allow initial scene recognition and high spatial frequencies (HSF) subsequently carry fine details analysis. In the present MRI study we studied for the first time in children the relationship between the cortical thickness and behavioral performances to LSF and HSF processes. Sixteen children (10 years old) were presented with natural scenes and they had to indicate as rapidly and as accurately as possible for each trial whether the scene was outdoor or indoor. Each scene was filtered either in LSF or in HSF. Children were scanned with a 3-Tesla MRI scanner, and mean cortical thickness values were extracted with Freesurfer software according to the Destrieux Atlas. Regression analyses, which included age as covariable, were computed to determine the degree of relationship between the cortical thickness and behavioral performances to LSF and HSF filtered scenes. The results indicated that children exhibited (1) faster reaction times to LSFs associated to a decreased cortical thickness in higher order cortical areas constituted of middle frontal, lateral orbital and insula regions and (2) faster reaction times to HSFs associated to an increased cortical thickness in parietal and calcarine regions. These findings constitute the first structural study that supports the hypothesis that both synaptic pruning (i.e., decreased cortical thickness) and expansion mechanisms (i.e., increased cortical thickness) co-occur to allow healthy children to develop an efficient perception of the visual world.

Abstract

International audience; Visual perception depends on the integration of local elements of a visual scene into a global frame. Evidence from behavioral studies shows that (1) the detection of the global frame is faster than the detection of the local parts, a phenomenon called the global advantage, and that (2) an interference of the global shape is also present during local processing. Together, these effects are called the global precedence effect (GPE). Even if the global advantage appears to impact neural processing as early as the first 100 ms post-stimulus, previous studies failed to find a global interference effect before 200 ms post-stimulus. Using for the first time a rapid display of letter component stimuli during a global/local selective task in which conditions with perceptual conflict, congruent and incongruent conditions were considered, the present event-related potential (ERP) study shows a global interference effect occurring as early as the time range of the N1 component. In particular, only congruent stimuli elicited similar N1 amplitude during the global and local tasks, whereas an increased of the N1 amplitude during the global task was observed (as compared to the local task) for both stimuli with perceptual conflict and incongruent stimuli. This finding corroborates the recent neural models of human visual perception.

Abstract

International audience; Converging developmental decision-making studies have demonstrated that until late adolescence, individuals prefer options for which the risk of a loss is low regardless of the final outcome. Recent works have shown a similar inability to consider both loss frequency and final outcome among adults. The current study aimed to identify developmental changes in feedback-monitoring ability to consider both loss frequency and final outcome in decision making under ambiguity. Children, adolescents, and adults performed an adapted version of the Soochow Gambling Task. Our results showed that children and adolescents presented an exclusive preference for options associated with infrequent punishment. In contrast, only adults seemed to consider both loss fre- quency and the final outcome by favoring the advantageous options when the frequency of losses was low. These findings sug- gest that the ability to integrate both loss frequency and final out- come develops with age. Moreover, the analysis of strategic adjustments following gains and losses reveals that adults switch less often after losses compared with children and adolescents.
