PLoS ONE, Vol. 8 No. 6 · 2013 · English · PLOS Scopus

It is well-known that the affective value of an environment can be relative to whether it reflects an improvement or a worsening from a previous state. A potential explanation for this phenomenon suggests that relative changes from previous reward contingencies can constrain how brain monitoring…

The Feedback-Related Negativity and the P300 Brain Potential Are Sensitive to Price Expectation Violations in a Virtual Shopping Task

Alexandre Schaefer; Luciano G. Buratto; Nobuhiko Goto et al.

PLOS ONE, Vol. 11 No. 9 · 2016 · English · PLOS Scopus

A large body of evidence shows that buying behaviour is strongly determined by consumers’ price expectations and the extent to which real prices violate these expectations. Despite the importance of this phenomenon, little is known regarding its neural mechanisms. Here we show that two patterns of…

The Effects of a Distracting N -Back Task on Recognition Memory Are Reduced by Negative Emotional Intensity

Luciano G. Buratto; Claire L. Pottage; Charity Brown et al.

PLoS ONE, Vol. 9 No. 10 · 2014 · English · PLOS Scopus

Memory performance is usually impaired when participants have to encode information while performing a concurrent task. Recent studies using recall tasks have found that emotional items are more resistant to such cognitive depletion effects than non-emotional items. However, when recognition tasks…
