Can 'Hebb' Be Distracted? Testing the Susceptibility of Sequence Learning to Auditory Distraction

Incidental learning in music reading: The music contingency learning task

The present report investigated whether nonmusicians can incidentally learn musical skills needed for sight-reading. On each trial, participants identified a note name written inside of a note on the musical staff. In Experiment 1, each note was presented frequently with the congruent note name (e.g., "do" with the note for "do") and rarely with the incongruent names (e.g., "do" with the note for "fa"). With or without deliberate learning instructions, a robust contingency learning effect was observed: faster responses for congruent trials compared with incongruent trials. Participants also explicitly identified the meaning of the note positions more accurately than chance. Experiment 2 ruled out the potential influence of preexisting knowledge on the contingency learning effect by presenting notes most often with an incongruent note name. Robust learning was again observed, suggesting that participants acquired sufficient knowledge of musical notation to produce automatic influences on behaviour (e.g., akin to the interference effect previously found in skilled musicians). A congruency effect was additionally observed in Experiment 2, however. Experiment 3 further explored to what extent this congruency effect might be due to prior music knowledge and/or spatial stimulus-response compatibility between note and response locations (analogous to the SMARC effect). Overall, our results open up new avenues for investigating the incidental learning of complex material, musical or otherwise, and for reinforcing learning even further.

Individual differences in selective attention and scanning dynamics influence children's learning from relevant non-targets in a visual search task

Efficient selective attention is critical for engaging in task-oriented behavior but may also limit our processing of potentially meaningful, task-irrelevant details. Both older adults and younger children demonstrate poor selective attention skills but show increased processing of task-irrelevant information. This broader attention to non-targets can benefit learning among older adults when the non-target information is relevant to a primary learning goal. Although young children show similar patterns of attention to non-targets, it is unknown whether relevant non-targets similarly benefit their learning. This study examined the relationship between 4- to 8-year-old children's selective attention skills and their learning from incidental exposure to relevant non-targets. In Experiment 1, children completed an incidental encoding phase, followed by a visual search task and then a final recognition memory task. During the search task, participants identified a target within arrays containing 0, 5, 10, or 15 non-targets. Half of the images from the encoding phase appeared in the search as "relevant" non-targets, whereas the remainder never appeared during the search task. Participants showed better memory for images presented as relevant non-targets. However, children showed the largest memory benefit when efficient selective attention allowed for increased scanning of the relevant non-targets after target detection. Experiment 2 confirmed that children showed similarly efficient selective attention skills but no longer showed enhanced learning when they could not scan relevant non-targets following target detection. These results suggest that children's incidental learning from relevant non-targets is an active process that depends on how children use selective attention to engage in effective information gathering.
