Salience is a core determinant of attentional processing. Although information on salience has been shown to dissipate within a few hundred milliseconds, we recently observed massive effects of salience on the delayed recall from visual working memory more than 1,300 ms after stimulus onset. Here, we manipulated presentation duration of the memory display and found that effects of salience, albeit decreasing over time, were still markedly present after 3,000 ms (2,000 ms presentation; Experiment 1). In an attempt to overrule this persistent influence of salience, we made less salient stimuli more relevant (by rewarding their prioritized processing in Experiment 2 or by probing them more often in Experiment 3). Participants were unable to reliably prioritize low-salience stimuli. Thus, our results demonstrate that effects of salience or their repercussions have surprisingly long-lasting effects on cognitive performance that reach even relatively late processing stages and are difficult to overrule by volition.

Self-Control Buffers the Mortality Salience Effect on Fairness-Related Decision-Making.

Fairness-related decision-making often involves a conflict between egoistic and prosocial motives. Previous research based on Terror Management Theory (TMT) indicates that mortality salience can promote both selfish and prosocial behaviors, leaving its effect on fairness-related decision-making uncertain. This study integrates TMT with the strength model of self-control to investigate the effects of mortality salience on fairness-related decision-making and to examine the moderating role of dispositional self-control.

The present study investigated the neuromodulatory substrates of salience processing and its impact on memory encoding and behaviour, with a specific focus on two distinct types of salience: reward and contextual unexpectedness. 46 Participants performed a novel task paradigm modulating these two aspects independently and allowing for investigating their distinct and interactive effects on memory encoding while undergoing high-resolution fMRI. By using advanced image processing techniques tailored to examine midbrain and brainstem nuclei with high precision, our study additionally aimed to elucidate differential activation patterns in subcortical nuclei in response to reward-associated and contextually unexpected stimuli, including distinct pathways involving in particular dopaminergic modulation.

The ability of environmental cues to trigger alcohol-seeking behaviours is thought to facilitate problematic alcohol use. Individuals' tendency to attribute incentive salience to cues may increase the risk of addiction. We sought to study the relationship between incentive salience and alcohol addiction using non-preferring rats to model the heterogeneity of human alcohol consumption, investigating both males and females.

Visual working memory (VWM) is a core cognitive system enabling us to select and briefly store relevant visual information. We recently observed that more salient items were recalled more precisely from VWM and demonstrated that these effects of salience resisted manipulations of reward, probability, and selection history. Here, we investigated whether and how salience interacts with shifts of attention induced by pre- and retrocueing.
