Motion perceptual learning: when only task-relevant information is learned.
The classic view that perceptual learning is information selective and goal directed has been challenged by recent findings showing that subthreshold and task-irrelevant information can induce perceptual learning. This study demonstrates a limit on task-irrelevant learning as exposure to suprathreshold task-irrelevant signals failed to induce perceptual learning. In each trial, two random-dot m...

متن کاملPerceptual Learning in the Absence of Task or Stimulus Specificity
Performance on most sensory tasks improves with practice. When making particularly challenging sensory judgments, perceptual improvements in performance are tightly coupled to the trained task and stimulus configuration. The form of this specificity is believed to provide a strong indication of which neurons are solving the task or encoding the learned stimulus. Here we systematically decouple ...
متن کاملLearning from Relevant Tasks Only
We introduce a problem called relevant subtask learning, a variant of multi-task learning. The goal is to build a classifier for a taskof-interest having too little data. We also have data for other tasks but only some are relevant, meaning they contain samples classified in the same way as in the task-of-interest. The problem is how to utilize this “background data” to improve the classifier i...
متن کاملEffect of spatial distance to the task stimulus on task-irrelevant perceptual learning of static Gabors.
It was previously shown that sensitivity improvements to a task-irrelevant motion direction can be obtained when it is presented in concurrence with observers' performance of an attended task (A. R. Seitz & T. Watanabe, 2003; T. Watanabe, J. E. Náñez, & Y. Sasaki, 2001). To test whether this task-irrelevant perceptual learning (TIPL) is specific for motion and to clarify the relationships betwe...
