N2 - Past research in animals has suggested that attention is distributed to exploit known relationships between stimuli (e.g., Mackintosh, 1975) and explore stimuli whose consequences are uncertain (e.g., Pearce & Hall, 1980). The resulting changes in attention influence how animals learn new information involving those stimuli. While there is strong support for exploitative attention and its effects on learning in humans, the evidence for exploratory attention is less well developed. Two experiments examined whether preferential allocation of attention (as measured by eye-gaze) to cues associated with uncertainty leads to more rapid learning of new associations involving these cues in the future. In each experiment, participants first learned about compounds containing one predictive cue and one non-predictive cue. The level of uncertainty during this first stage of training was also manipulated: cue-outcome relationships were either deterministic (certain) or probabilistic (uncertain).
