Christophe Carlei, Dirk Kerzel
The orientation-bias hypothesis states that there is a bias to attend to the right visual hemifield (RVF) when there is spatial competition between stimuli in the left and right hemifield [Pollmann, S. (1996). A pop-out induced extinction-like phenomenon in neurologically intact subjects. Neuropsychologia, 34(5), 413-425. doi: 10.1016/0028-3932(95)00125-5 ]. In support of this hypothesis, stronger interference was reported for RVF distractors with contralateral targets. In contrast, previous studies using rapid serial visual presentation (RSVP) found stronger interference from distractors in the left visual hemifield (LVF)...

A growing body of literature suggests that human individuals differ in their ability to process face identity. These findings mainly stem from explicit behavioral tasks, such as the Cambridge Face Memory Test (CFMT). However, it remains an open question whether such individual differences can be found in the absence of an explicit face identity task and when faces have to be individualized at a single glance. In the current study, we tested 49 participants with a recently developed fast periodic visual stimulation (FPVS) paradigm [Liu-Shuang, J...

In a recent amendment to the two-visual-system model, it has been proposed that actions must result in tactile contact with the goal object for the dorsal system to become engaged (Whitwell et al., Neuropsychologia 55:41-50, 2014). The present study tested this addition by assessing the use of allocentric information in normal and pantomime actions. To this end, magicians, and participants who were inexperienced in performing pantomime actions made normal and pantomime grasps toward objects embedded in the Müller-Lyer illusion...

The manual estimation task requires that participants separate the distance between their thumb and forefinger until they perceive it to match the size of a target object. Ganel and colleagues (Curr Biol 18:R599-R601, 2008a) demonstrated that manual estimations yield just-noticeable-difference (JND) scores that linearly increased with increasing target object size; that is, responses adhered to Weber's law and thus evince response mediation via relative and perception-based visual information. In turn, more recent work has reported that the size of a target object influences whether JNDs provide a reliable metric for evaluating the nature of the visual information supporting manual estimations...

Physical size modulates the efficiency of digit comparison, depending on whether the relation of numerical magnitude and physical size is congruent or incongruent (Besner & Coltheart, Neuropsychologia, 17, 467-472, 1979), the number-size congruency effect (NSCE). In addition, Henik and Tzelgov (Memory & Cognition, 10, 389-395, 1982) first reported an NSCE for the reverse task of comparing the physical size of digits such that the numerical magnitude of digits modulated the time required to compare their physical sizes...

The visual system is extremely efficient at detecting events across time even at very fast presentation rates; however, discriminating the identity of those events is much slower and requires attention over time, a mechanism with a much coarser resolution [Cavanagh, P., Battelli, L., & Holcombe, A. O. Dynamic attention. In A. C. Nobre & S. Kastner (Eds.), The Oxford handbook of attention (pp. 652-675). Oxford: Oxford University Press, 2013]. Patients affected by right parietal lesion, including the TPJ, are severely impaired in discriminating events across time in both visual fields [Battelli, L...

INTRODUCTION: Patients with amnestic mild cognitive impairment (a-MCI) are deficient in storing memory traces relative to recollective forms of declarative memory. Controversial data have, instead, been reported concerning the storage of new memory traces relative to familiarity, with some studies reporting impairment and others sparing of the storage of this form of memory. No data have been reported concerning the consolidation of recollection and familiarity memory traces subsequent to their storage...

The present study aimed to evaluate whether increased activity related to speech motor preparation preceding fluently produced words reflects a successful compensation strategy in stuttering. For this purpose, a contingent negative variation (CNV) was evoked during a picture naming task and measured by use of electro-encephalography. A CNV is a slow, negative event-related potential known to reflect motor preparation generated by the basal ganglia-thalamo-cortical (BGTC) - loop. In a previous analysis, the CNV of 25 adults with developmental stuttering (AWS) was significantly increased, especially over the right hemisphere, compared to the CNV of 35 fluent speakers (FS) when both groups were speaking fluently (Vanhoutte et al...

McKensie M Worley, David B Boles
We used factor analysis to examine relationships among tasks that have previously shown right hemispheric processing asymmetries. We were interested in whether processing emotion displayed by a face constitutes a distinct perceptual process from processing other facial characteristics. Interest in this topic arose after Boles [ 1991 . Factor analysis and the cerebral hemispheres: Pilot study and parietal functions. Neuropsychologia, 29 ( 1 ), 59 - 91 ] found evidence of a common process underlying face processing and then Boles [ 1992 ...

Phil Bryden's work has impacted on many areas of laterality, including degree and measurement of hand preference, as well as influences of familial sinistrality (FS). For example, Bryden[(1977). Measuring handedness with questionnaires. Neuropsychologia, 15, 617-624] is a well-cited and influential paper that remains relevant to this day. Inspired by this we extended our analysis of the relationship between handedness and anxiety in a number of ways. We used familial handedness and strength of handedness to examine their potential influences on anxiety, and extended our research by exploring their relationship to social anxiety, using the Social Phobia Inventory (SPIN)...

Evidence is accumulating that the classic two-stage model of visual STM (VSTM), comprising iconic memory (IM) and visual working memory (WM), is incomplete. A third memory stage, termed fragile VSTM (FM), seems to exist in between IM and WM [Vandenbroucke, A. R. E., Sligte, I. G., & Lamme, V. A. F. Manipulations of attention dissociate fragile visual STM from visual working memory. Neuropsychologia, 49, 1559-1568, 2011; Sligte, I. G., Scholte, H. S., & Lamme, V. A. F.

Grasping behavior is being tested increasingly often in virtual and mirror setups. In displays where the visual percept does not correspond to physical reality (e.g., distorted depth perception under limited cue conditions) an important methodological question is what and how much haptic feedback to provide. While grasping without haptic feedback has been shown to drift, both in position and aperture size (Bingham, Coats, & Mon-Williams, 2007, Neuropsychologia, 45, 288-294), grasping with terminal haptic feedback that does not correspond to the visual information has been shown to bias both reaching distance and maximum grip aperture (MGA) in the direction of the haptic feedback (Mon-Williams & Bingham, 2007, JEP:HPP, 33, 645-656; Coats, Bingham, & Mon-Williams, 2008, Experimental Brain Research, 189, 211-220)...

Allison Sekuler, Matthew Pachai, Ali Hashemi, Patrick Bennett
One possible explanation for the face inversion effect (FIE) is that inversion swaps the eye and mouth locations relative to fixation, and attention typically is directed to the top of a stimulus for faces. As the eye region is the most informative for face discrimination, automatically attending to the upper-half of a face would cause observers to use less diagnostic regions for inverted faces. Consistent with this hypothesis, cueing attention to the eyes modulates the FIE measured both behaviourally (Hills et al...

Although human adults can learn to individualize novel 3D multiparts objects, there is little evidence that their visual representations are modified following learning. To address this issue, we developed 3D objects where the global structure, parts and their configuration, as well as the texture can be parametrically manipulated to create large sets of stimuli with individual variations. Importantly, parts are configured so that stimuli appear as "face-like" in one orientation. We trained two groups of 11 subjects to become experts at individuating 26 novel object exemplars, either in face-like or non-face-like orientation...

When perceiving symmetry, an ERP component known as the Sustained Posterior Negativity (SPN) is produced. From around 250ms, amplitudes in posterior electrodes are more negative for symmetrical than random patterns (Makin et al., 2012). This component is thought to be spread over both hemispheres. A role for the corpus callosum has also been highlighted when symmetrical patterns are presented at fixation (Herbert & Humphrey, 1996). We tested this callosal hypothesis by measuring SPN response to peripheral stimuli...
