Selection bias in information-search contributes to the formation of polarized echo-chambers of beliefs. However, the role of valence in information source selection remains poorly understood. In Experiment 1, participants won financial rewards depending on the outcomes of a set of lotteries. They were not shown these outcomes, but instead could ch...

How we exert control over our decision-making has been investigated using conflict tasks, which involve stimuli containing elements that are either congruent or incongruent. In these tasks, participants adapt their decision-making strategies following exposure to incongruent stimuli. According to conflict monitoring accounts, conflicting stimulus f...

Curiosity pervades all aspects of human behaviour and decision-making. Recent research indicates that the value of information is determined by its propensity to reduce uncertainty, and the hedonic value of the outcomes it predicts. Previous findings also indicate a preference for options that are freely chosen, compared to equivalently valued alte...

... These results suggest that frontal ERS plays an important role in maintaining behavioral stability, and the decrease in frontal theta activity is an important factor affecting the behavior pattern of children with ADHD. In addition, we found a trial-based positive correlation between midfrontal theta ERS and RT in the ADHD group, which is similar to the results in studies on conflict processes (47)(48)(49). These findings are thought to reflect an important functional role of midfrontal theta-band oscillations in conflict monitoring and top-down control of decision making. ...
... There has been some work on query formation in Library and Information Science (LIS) [70,96], much conceptual in nature. There is some empirical work asking participants to generate queries in response to a stated information need (e.g., [57]), the work is limited to artificial information needs, an approach that results in less user curiosity about the results and therefore likely changed behavior [54]. A handful of test collections were created that examine query variations [9,23], but that research has focused on the impact of the variation on search results, rather than a query's origin. ...
