Previewing distracters reduces their effective contrast (2007)
Journal Article

In a visual search task, when half the distracters are presented earlier than the remainder (‘previewed’), observers find the target item more efficiently than when all the items are presented together—the preview benefit. We measured psychometric fu... Read More about Previewing distracters reduces their effective contrast.

Amphetamine and the adenosine A2A antagonist KW-6002 enhance the effects of conditional temporal probability of a stimulus in rats (2007)
Journal Article

As the length of foreperiod preceding an imperative signal increases, reaction time decreases and anticipatory (prior to the signal) responding increases. The authors designed a task to dissociate the effect of elapsing time in the foreperiod and con...

The effect of striatal dopamine depletion and the adenosine A2A antagonist KW-6002 on reversal learning in rats (2007)
Journal Article

This study assessed whether dopamine in the dorsomedial striatum is necessary for flexible adaptation to changes in stimulus–response contingencies. As KW-6002 (Istradefylline), an adenosine A2A antagonist, improves motor deficits resulting from stri...

A psychophysical investigation into the preview benefit in visual search (2007)
Journal Article

In preview search, half of the distracters are presented ahead of the remaining distracters and the target. Search under these conditions is more efficient than when all the items appear together (Watson & Humphreys, 1997). We investigated the mechan...

Ventral extra-striate cortical areas are required for optimal orientation averaging (2007)
Journal Article

We examined the ability of a previously well-studied patient with visual agnosia to compute the average orientation of elements in visual displays. In a structural MRI study, we show that the lesion is likely to involve a variety of ventral extra-str...

Self-ordered pointing as a test of working memory in typically developing children (2007)
Journal Article

The self-ordered pointing test (SOPT; Petrides & Milner, 1982) is a test of non-spatial executive working memory requiring the ability to generate and monitor a sequence of responses. Although used with developmental clinical populations there are... Read More about Self-ordered pointing as a test of working memory in typically developing children.

Error analyses reveal contrasting deficits in “theory of mind”: neuropsychological evidence from a 3-option false belief task (2007)
Journal Article

Perspective taking is a crucial ability that guides our social interactions. In this study, we show how the specific patterns of errors of brain-damaged patients in perspective taking tasks can help us further understand the factors contributing to p...

When “happy” means “sad”: neuropsychological evidence for the right prefrontal cortex contribution to executive semantic processing (2007)
Journal Article

The contribution of the left inferior prefrontal cortex in semantic processing has been widely investigated in the last decade. Converging evidence from functional imaging studies shows that this region is involved in the “executive” or “controlled”...
