Edlin, James M.; Lyle, Keith B. – Brain and Cognition, 2013
The simple act of repeatedly looking left and right can enhance subsequent cognition, including divergent thinking, detection of matching letters from visual arrays, and memory retrieval. One hypothesis is that saccade execution enhances subsequent cognition by altering attentional control. To test this hypothesis, we compared performance…

Bramao, Ines; Faisca, Luis; Forkstam, Christian; Inacio, Filomena; Araujo, Susana; Petersson, Karl Magnus; Reis, Alexandra – Brain and Cognition, 2012
In this study, we used event-related potentials (ERPs) to evaluate the contribution of surface color and color knowledge information in object identification. We constructed two color-object verification tasks--a surface and a knowledge verification task--using high color diagnostic objects; both typical and atypical color versions of the same…

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…

Marotta, Andrea; Lupianez, Juan; Casagrande, Maria – Brain and Cognition, 2012
Recent studies have demonstrated that central cues, such as eyes and arrows, reflexively trigger attentional shifts. However, it is not clear whether the attentional mechanisms induced by these two cues are similar or rather differ in some important way. We investigated hemispheric lateralization of the orienting effects induced by the two cue…

Viard, Armelle; Desgranges, Beatrice; Eustache, Francis; Piolino, Pascale – Brain and Cognition, 2012
Remembering the past and envisioning the future are at the core of one's sense of identity. Neuroimaging studies investigating the neural substrates underlying past and future episodic events have been growing in number. However, the experimental paradigms used to select and elicit episodic events vary greatly, leading to disparate results,…

Gullick, Margaret M.; Temple, Elise – Brain and Cognition, 2011
While numbers generally cue processing of quantity or order, they can also contain semantic information, as in the case of historic years (e.g., "1492" calls forth associations of Columbus sailing the ocean blue). Whether these dates are processed as quantities or events may depend on the context in which they occur. We examined such "ambiguous…

Salo, Ruth; Gabay, Shai; Fassbender, Catherine; Henik, Avishai – Brain and Cognition, 2011
Objective: The goal of the present study was to examine distributed attentional functions in long-term but currently abstinent methamphetamine (MA) abusers using a task that measures attentional alertness, orienting, and conflict resolution. Methods: Thirty currently abstinent MA abusers (1 month-5 years) and 22 healthy non-substance using adults…

Calabria, Marco; Miniussi, Carlo; Bisiacchi, Patricia S.; Zanetti, Orazio; Cotelli, Maria – Brain and Cognition, 2009
Repetition priming (RP) has been employed as a measure of implicit processing in patients suffering from a breakdown of semantic memory, as in the case of semantic dementia (SD), a subtype of frontotemporal lobar degeneration (FTLD). Here, we investigated face-name representation in a case of SD using a paradigm of within- and cross-domain…

Correa, Angel; Trivino, Monica; Perez-Duenas, Carolina; Acosta, Alberto; Lupianez, Juan – Brain and Cognition, 2010
Temporal preparation and impulsivity involve overlapping neural structures (prefrontal cortex) and cognitive functions (response inhibition and time perception), however, their interrelations had not been investigated. We studied such interrelations by comparing the performance of groups with low vs. high non-clinical trait impulsivity during a…

Poynter, William; Ingram, Paul; Minor, Scott – Brain and Cognition, 2010
The purpose of this study was to determine whether an index of self-reported attention deficits predicts the pattern of visual field asymmetries observed in behavioral measures of attention. Studies of "normal" subjects do not present a consistent pattern of asymmetry in attention functions, with some studies showing better left visual field (LVF)…

Teuscher, Ursina; Brang, David; Ramachandran, Vilayanur S.; Coulson, Seana – Brain and Cognition, 2010
Some people report that they consistently and involuntarily associate time events, such as months of the year, with specific spatial locations; a condition referred to as time-space synesthesia. The present study investigated the manner in which such synesthetic time-space associations affect visuo-spatial attention via an endogenous cuing…

Tsai, Chia-Liang; Pan, Chien-Yu; Cherng, Rong-Ju; Hsu, Ya-Wen; Chiu, Hsing-Hui – Brain and Cognition, 2009
The purpose of this study was to investigate and compare the mechanisms of brain activity, as revealed by a combination of the visuospatial attention shifting paradigm and event-related potentials (ERP) in children with developmental coordination disorder (DCD) and typically developing children. Twenty-eight DCD children and 26 typically…

Bish, Joel P.; Chiodo, Renee; Mattei, Victoria; Simon, Tony J. – Brain and Cognition, 2007
One of the defining cognitive characteristics of the chromosome 22q deletion syndrome (DS22q11.2) is visuospatial processing impairments. The purpose of this study was to investigate and extend the specific attentional profile of children with this disorder using both an object-based attention task and an inhibition of return task. A group of…
