Some years ago an improved design (the "complete design") was proposed to assess the composite face effect in terms of a congruency effect, defined as the performance difference for congruent and incongruent target to no-target relationships (Cheung et al., 2008). In a recent paper Rossion(2013) questioned whether the congruency effect was a valid hallmark of perceptual integration, because it may contain confounds with face-unspecific interference effects. Here we argue that the complete design is well-balanced and allows one to separate face-specific from face-unspecific effects. We used the complete design for a same/different composite stimulus matching task with face and non-face objec…

Data from: Orientation-invariance of individual differences in three face processing tasks

2018

Numerous studies have reported impairments in perception and recognition, and, particularly, in part-integration of faces following picture-plane inversion. Whether these findings support the notion that inversion changes face processing qualitatively remains a topic of debate. To examine whether associations and dissociations of the human face processing ability depend on stimulus orientation, we measured face recognition with the Cambridge Face Memory Test (CFMT), along with experimental tests of face perception and selective attention to faces and non-face objects in a sample of 314 participants. Results showed strong inversion effects for all face-related tasks, and modest ones for non-…

Visual Attention, Orthographic Word Recognition, and Executive Functioning in Children With ADHD, Dyslexia, or ADHD + Dyslexia

2019

Objective: The current study examined the differences in visual selective attention, orthographic word recognition, and executive functioning. Method: One hundred and forty Ecuadorian children in third and fifth grades of elementary school (8-10 years old) participated in the study—35 with only dyslexia (DD), 35 with the combined type of attention deficit and hyperactivity disorder (ADHD-C), 35 with disorders (DD + ADHD-C), and 35 typical development children (TD). Results: The Ecuadorian children with DD and/or ADHD-C in this age range usually have difficulties in visual selective attention, and also in orthographic word recognition. The executive functioning results showed that such func…

Motor and cognitive growth following a Football Training Program

2015

Football may be a physical and sport activities able to improve motor and cognitive growth in children. Therefore the aim of this study was to assess whether a Football Training Program taken over 6 months would improve motor and cognitive performances in children. Motor skills concerned coordinative skills, running and explosive legs strength. Cognitive abilities involved visual discrimination times and visual selective attention times.Forty-six children with chronological age of ~9.10 years, were divided into two groups: Group 1 (n=24) attended a Football Exercise Program and Group 2 (n=22) was composed of sedentary children.Their abilities were measured by a battery of tests including mo…

Using Temporal Expectation to Assess Auditory Streaming in Mice

2018

Auditory streaming is the process by which environmental sound is segregated into discrete perceptual objects. The auditory system has a remarkable capability in this regard as revealed in psychophysical experiments in humans and other primates. However, little is known about the underlying neuronal mechanisms, in part because of the lack of suitable behavioural paradigms in non-primate species. The mouse is an increasingly popular model for studying the neural mechanisms of perception and action because of the range of molecular tools enabling precise manipulation of neural circuitry. Here we present a novel behavioural task that can be used to assess perceptual aspects of auditory streami…
