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...

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. Are there multiple visual STM stores? PLoS One, 3, e1699, 2008]...

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)...

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...

UNLABELLED: Embodiment theories hypothesize that the perception of emotions from body movements involves an activation of brain structures that are involved in motor execution during social interaction [1,2]. This predicts that, for identical visual stimulation, bodily emotions should be perceived as more expressive when the observers are involved in social motor behavior. We tested this hypothesis, exploiting advanced VR technology, requiring participants to judge the emotions of an avatar that reacted to their own motor behavior...

A long-standing debate in the recognition-memory literature concerns which model provides the best account. Prominent candidates in this debate are the unequal-variance signal detection model (UVSD), the dual-process model (DPSD), and two versions of the mixture model (MSD). The present work evaluates a recently proposed ROC-based method for comparing these models (Dede, Squire, & Wixted, Neuropsychologia, 54, 51-56, 2014). This method consists of evaluating the pattern of residuals produced by each model's best fits to ROC data...

We investigated cognitive and affective Theory of Mind (ToM) and empathy in patients with premanifest and manifest Huntington's disease (HD). The relationship between ToM performance and executive skills was also examined. Sixteen preclinical and 23 clinical HD patients, and 39 healthy subjects divided into 2 control groups were given a French adaptation of the Yoni test (Shamay-Tsoory, S.G., Aharon-Peretz, J. (2007). Dissociable prefrontal networks for cognitive and affective theory of mind: a lesion study...

Healthy adults bisect visual horizontal lines slightly to the left of their true center. This bias has been termed "pseudoneglect" and is considered to reflect right hemisphere dominance in the orienting of spatial attention. A previous investigation reported a positive correlation between pseudoneglect and a corresponding negative bias towards numbers lower than the true midpoint, i.e. supposedly to the left of the midpoint, during the mental bisection of number intervals that were defined by two visual arabic digits presented one to the left and one to the right of a horizontal line (Longo and Lourenco, 2007, Neuropsychologia, 45, 7, 1400-1407)...

In human adults the use of visual information for selecting appropriate modes for action appears to be separate from the use of visual information for the control of movements of which the action is composed (Milner & Goodale, [1995] The visual brain in action; [2008] Neuropsychologia 46:774-785). More specifically, action mode selection primarily relies upon allocentric information, whereas movement control mainly exploits egocentric information. In the present study, we investigated to what degree this division is already present in 6- to 10-month-old infants when reaching for moving objects; that is, whether allocentric information is uniquely exploited for action mode selection (i...

Motor learning occurs not only through direct first-hand experience but also through observation (Mattar AA, Gribble PL. Neuron 46: 153-160, 2005). When observing the actions of others, we activate many of the same brain regions involved in performing those actions ourselves (Malfait N, Valyear KF, Culham JC, Anton JL, Brown LE, Gribble PL. J Cogn Neurosci 22: 1493-1503, 2010). Links between neural systems for vision and action have been reported in neurophysiological (Strafella AP, Paus T. Neuroreport 11: 2289-2292, 2000; Watkins KE, Strafella AP, Paus T...

INTRODUCTION: A functional activation (i.e., ordinal trend) pattern was previously identified in both young and older adults during task-switching performance, the expression of which correlated with reaction time. The current study aimed to (1) replicate this functional activation pattern in a new group of fMRI activation data, and (2) extend the previous study by specifically examining whether the effect of aging on reaction time can be explained by differences in the activation of the functional activation pattern...

BACKGROUND: Several studies have demonstrated a bilateral field advantage (BFA) in early visual attentional processing, that is, enhanced visual processing when stimuli are spread across both visual hemifields. The results are reminiscent of a hemispheric resource model of parallel visual attentional processing, suggesting more attentional resources on an early level of visual processing for bilateral displays [e.g. Sereno AB, Kosslyn SM. Discrimination within and between hemifields: a new constraint on theories of attention...
