Mullally, Sinead L.; Maguire, Eleanor A. – Brain and Cognition, 2013
It has recently been observed that certain objects, when viewed or imagined in isolation, evoke a strong sense of three-dimensional local space surrounding them (space-defining (SD) objects), while others do not (space-ambiguous (SA) objects), and this is associated with engagement of the parahippocampal cortex (PHC). But activation of the PHC is…

Baeken, Chris; Van Schuerbeek, Peter; De Raedt, Rudi; Vanderhasselt, Marie-Anne; De Mey, Johan; Bossuyt, Axel; Luypaert, Robert – Brain and Cognition, 2012
The amygdalae are key players in the processing of a variety of emotional stimuli. Especially aversive visual stimuli have been reported to attract attention and activate the amygdalae. However, as it has been argued that passively viewing withdrawal-related images could attenuate instead of activate amygdalae neuronal responses, its role under…

Buiatti, Tania; Skrap, Miran; Shallice, Tim – Brain and Cognition, 2013
Damage to the posterior parietal cortex (PPC) can lead to Optic Ataxia (OA), in which patients misreach to peripheral targets. Recent research suggested that the PPC might be involved not only in simple reaching tasks toward peripheral targets, but also in changing the hand movement trajectory in real time if the target moves. The present study…

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…

Hilti, Caroline C.; Jann, Kay; Heinemann, Doerthe; Federspiel, Andrea; Dierks, Thomas; Seifritz, Erich; Cattapan-Ludewig, Katja – Brain and Cognition, 2013
The deterioration of performance over time is characteristic for sustained attention tasks. This so-called "performance decrement" is measured by the increase of reaction time (RT) over time. Some behavioural and neurobiological mechanisms of this phenomenon are not yet fully understood. Behaviourally, we examined the increase of RT over time and…

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…

Dreisbach, Gesine; Fischer, Rico – Brain and Cognition, 2012
Theories of human action control deal with the question of how cognitive control is dynamically adjusted to task demands. The conflict monitoring theory of anterior cingulate (ACC) function suggests that the ACC monitors for response conflicts in the ongoing processing stream thereby triggering the mobilization of cognitive control. Alternatively,…

Asanowicz, Dariusz; Marzecova, Anna; Jaskowski, Piotr; Wolski, Piotr – Brain and Cognition, 2012
Despite the fact that hemispheric asymmetry of attention has been widely studied, a clear picture of this complex phenomenon is still lacking. The aim of the present study was to provide an efficient and reliable measurement of potential hemispheric asymmetries of three attentional networks, i.e. alerting, orienting and executive attention.…

de Fockert, Jan W.; Theeuwes, Jan – Brain and Cognition, 2012
The role of frontal cortex in selective attention to visual distractors was examined in an attentional capture task in which participants searched for a unique shape in the presence or absence of an additional colour singleton distractor. The presence of the additional singleton was associated with slower behavioural responses to the shape target,…

Burnham, Bryan R.; Rozell, Cassandra A.; Kasper, Alex; Bianco, Nicole E.; Delliturri, Antony – Brain and Cognition, 2011
The present study examined a visual field asymmetry in the contingent capture of attention that was previously observed by Du and Abrams (2010). In our first experiment, color singleton distractors that matched the color of a to-be-detected target produced a stronger capture of attention when they appeared in the left visual hemifield than in the…

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…

Ocklenburg, Sebastian; Gunturkun, Onur; Beste, Christian – Brain and Cognition, 2012
Although functional cerebral asymmetries (FCAs) affect all cognitive domains, their modulation of the efficacy of specific executive functions is largely unexplored. In the present study, we used a lateralized version of the task switching paradigm to investigate the relevance of hemispheric asymmetries for cognitive control processes. Words were…

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…

Andreau, Jorge Mario; Funahashi, Shintaro – Brain and Cognition, 2011
The prefrontal cortex (PFC) is known to contribute to memory processes such as encoding representations into long-term-memory (LTM) and retrieving these representations from LTM. However, the details of the PFC's contribution to LTM processes are not well known. To examine the characteristics of the PFC's contribution to LTM processes, we analyzed…

Brodeur, Mathieu B.; Debruille, J. Bruno; Renoult, Louis; Prevost, Marie; Dionne-Dostie, Emmanuelle; Buchy, Lisa; Lepage, Martin – Brain and Cognition, 2011
The present study was carried out to examine how the event-related potentials to fragmentation predict recognition success. Stimuli were abstract meaningless figures that were either complete or fragmented to various extents but still recoverable. Stimuli were first encoded as part of a symmetry discrimination task. In a subsequent recognition…
