Merck, Catherine; Jonin, Pierre-Yves; Vichard, Helene; Boursiquot, Sandrine Le Moal; Leblay, Virginie; Belliard, Serge – Brain and Language, 2013
Category-specific deficits have rarely been reported in semantic dementia (SD). To our knowledge, only four previous studies have documented category-specific deficits, and these have focused on the living versus non-living things contrast rather than on more fine-grained semantic categories. This study aimed to determine whether a…

Reichelt, Amy C.; Killcross, Simon; Hambly, Luke D.; Morris, Margaret J.; Westbrook, R. Fred – Learning & Memory, 2015
In this study we sought to determine the effect of daily sucrose consumption in young rats on their subsequent performance in tasks that involve the prefrontal cortex and hippocampus. High levels of sugar consumption have been associated with the development of obesity, however less is known about how sugar consumption influences behavioral…

Bowler, Dermot M.; Gaigg, Sebastian B.; Gardiner, John M. – Journal of Autism and Developmental Disorders, 2014
Diminished episodic memory and diminished use of semantic information to aid recall by individuals with autism spectrum disorder (ASD) are both thought to result from diminished relational binding of elements of complex stimuli. To test this hypothesis, we asked high-functioning adults with ASD and typical comparison participants to study grids in…

Radvansky, Gabriel A.; Gibson, Bradley S.; McNerney, M. Windy – Journal of Experimental Psychology: Learning, Memory, and Cognition, 2011
In the current study, we explored the influence of synesthesia on memory for word lists. We tested 10 grapheme-color synesthetes who reported an experience of color when reading letters or words. We replicated a previous finding that memory is compromised when synesthetic color is incongruent with perceptual color. Beyond this, we found that,…

Diana, Rachel A.; Yonelinas, Andrew P.; Ranganath, Charan – Journal of Experimental Psychology: Learning, Memory, and Cognition, 2008
Performance on tests of source memory is typically based on recollection of contextual information associated with an item. However, recent neuroimaging results have suggested that the perirhinal cortex, a region thought to support familiarity-based item recognition, may support source attributions if source information is encoded as a feature of…

Gilbert, Aubrey L.; Regier, Terry; Kay, Paul; Ivry, Richard B. – Brain and Language, 2008
Recent work has shown that Whorf effects of language on color discrimination are stronger in the right visual field than in the left. Here we show that this phenomenon is not limited to color: The perception of animal figures (cats and dogs) was more strongly affected by linguistic categories for stimuli presented to the right visual field than…

Robinson, Astri J.; Pascalis, Olivier – Developmental Science, 2004
Research using the visual paired comparison task has shown that visual recognition memory across changing contexts is dependent on the integrity of the hippocampal formation in human adults and in monkeys. The acquisition of contextual flexibility may contribute to the change in memory performance that occurs late in the first year of life. To…
