Kranczioch, Cornelia; Dhinakaran, Janani – Brain and Cognition, 2013
The perception of target events presented in a rapid stream of non-targets is impaired for early target positions, but then gradually improves, a phenomenon known as attentional awakening. This phenomenon has been associated with better resource allocation. It is unclear though whether improved resource allocation and attentional awakening are a…

Kloth, Nadine; Itier, Roxane J.; Schweinberger, Stefan R. – Brain and Cognition, 2013
The face-sensitive N170 is typically enhanced for inverted compared to upright faces. Itier, Alain, Sedore, and McIntosh (2007) recently suggested that this N170 inversion effect is mainly driven by the eye region which becomes salient when the face configuration is disrupted. Here we tested whether similar effects could be observed with non-face…

Motz, Benjamin A.; Erickson, Molly A.; Hetrick, William P. – Brain and Cognition, 2013
Humans perceive a wide range of temporal patterns, including those rhythms that occur in music, speech, and movement; however, there are constraints on the rhythmic patterns that we can represent. Past research has shown that sequences in which sounds occur regularly at non-metrical locations in a repeating beat period (non-integer ratio…

Hughes, Andrew J.; Rutherford, Barbara J. – Brain and Cognition, 2013
Two experiments extend the ecological validity of tests of hemispheric interaction in three novel ways. First, we present a broad class of naturalistic stimuli that have not yet been used in tests of hemispheric interaction. Second, we test whether probable differences in complexity within the class of stimuli are supported by outcomes from…

Suegami, Takashi; Laeng, Bruno – Brain and Cognition, 2013
It has been shown that the left and right cerebral hemispheres (LH and RH) respectively process qualitative or "categorical" spatial relations and metric or "coordinate" spatial relations. However, categorical spatial information could be thought as divided into two types: semantically-coded and visuospatially-coded categorical information. We…

Holmes, Scott A.; Heath, Matthew – Brain and Cognition, 2013
An issue of continued debate in the visuomotor control literature surrounds whether a 2D object serves as a representative proxy for a 3D object in understanding the nature of the visual information supporting grasping control. In an effort to reconcile this issue, we examined the extent to which aperture profiles for grasping 2D and 3D objects…

Riby, Leigh M.; Orme, Elizabeth – Brain and Cognition, 2013
In this study we quantify for the first time electrophysiological components associated with incorporating long-term semantic knowledge with visuo-spatial information using two variants of a traditional matrix patterns task. Results indicated that the matrix task with greater semantic content was associated with enhanced accuracy and RTs in a…

Vuontela, Virve; Jiang, Ping; Tokariev, Maksym; Savolainen, Petri; Ma, YuanYe; Aronen, Eeva T.; Fontell, Tuija; Liiri, Tiina; Ahlstrom, Matti; Salonen, Oili; Carlson, Synnove – Brain and Cognition, 2013
Developmental studies have demonstrated that cognitive processes such as attention, suppression of interference and memory develop throughout childhood and adolescence. However, little is currently known about the development of top-down control mechanisms and their influence on cognitive performance. In the present study, we used functional…

Lv, Caixia; Wang, Quanhong – Brain and Cognition, 2012
Event-related brain potentials (ERPs) were recorded during a Chinese character decision task to examine whether N400 amplitude is modulated by stimulus font. Results revealed large negative-going ERPs in an N400 time window of 300-500 ms to stimuli presented in degraded Xing Kai Ti (XKT) font compared with more intact Song Ti (ST) font regardless…

Clifford, Alexandra; Franklin, Anna; Holmes, Amanda; Drivonikou, Vicky G.; Ozgen, Emre; Davies, Ian R. L. – Brain and Cognition, 2012
Category training can induce category effects, whereby color discrimination of stimuli spanning a newly learned category boundary is enhanced relative to equivalently spaced stimuli from within the newly learned category (e.g., categorical perception). However, the underlying mechanisms of these acquired category effects are not fully understood.…

Rossion, Bruno; Hanseeuw, Bernard; Dricot, Laurence – Brain and Cognition, 2012
A number of human brain areas showing a larger response to faces than to objects from different categories, or to scrambled faces, have been identified in neuroimaging studies. Depending on the statistical criteria used, the set of areas can be overextended or minimized, both at the local (size of areas) and global (number of areas) levels. Here…

Saetrevik, Bjorn; Specht, Karsten – Brain and Cognition, 2012
It has previously been shown that task performance and frontal cortical activation increase after cognitive conflict. This has been argued to support a model of attention where the level of conflict automatically adjusts the amount of cognitive control applied. Conceivably, conflict could also modulate lower-level processing pathways, which would…

Ramon, Meike; Rossion, Bruno – Brain and Cognition, 2012
In two behavioral experiments involving lateralized stimulus presentation, we tested whether one of the most commonly used measures of holistic face processing--the composite face effect--would be more pronounced for stimuli presented to the right as compared to the left hemisphere. In experiment 1, we investigated the composite face effect in a…

Williamson, Victoria J.; Cocchini, Gianna; Stewart, Lauren – Brain and Cognition, 2011
Congenital amusia manifests as a lifelong difficulty in making sense of musical sound. The extent to which this disorder is accompanied by deficits in visuo-spatial processing is an important question, bearing on the issue of whether pitch processing draws on supramodal spatial representations. The present study assessed different aspects of…

Page, Jonathan W.; Duhamel, Paul; Crognale, Michael A. – Brain and Cognition, 2011
Recent neuroimaging research suggests that early visual processing circuits are activated similarly during visualization and perception but have not demonstrated that the cortical activity is similar in character. We found functional equivalency in cortical activity by recording evoked potentials while color and luminance patterns were viewed and…
