Using fMRI, we investigated the functional organization of prefrontal cortex (PFC) as participants briefly thought of a single just-experienced item (i.e., refreshed an active representation). The results of six studies, and a meta-analysis including previous studies, identified regions in left dorsolateral, anterior, and ventrolateral PFC associated in varying degrees with refreshing different types of information (visual and auditory words, drawings, patterns, people, places, or locations). In addition, activity increased in anterior cingulate with selection demands and in orbitofrontal cortex when a nonselected item was emotionally salient, consistent with a role for these areas in cognitive control (e.g., overcoming "mental rubbernecking"). …

The assumption that positive affect leads to a better performance in various cognitive tasks has become well established. We investigate whether positive and negative emotions influence performance and strategies in complex problem solving. 74 male and female university students were tested in an experiment, using feedback-induced emotions and a computer-simulated scenario. Contrary to what has been expected, emotions did not affect success in scenario control. However, participants with negative emotions did show more information-oriented strategies in the scenario. We further tested whether control beliefs as a trait influence scenario control and moderate the relation between emotions and complex problem solving. …
