Changes in Neural Correlates of Outcome Feedback Processing During Implicit Learning

چکیده
In recent years, the neural substrates underlying outcome feedback processing have been investigated in several neuroimaging studies of feedback-based learning. However, what has been missed in these studies is that, the learning process itself also affects the way the feedback is being processed. In this study, we tried to investigate the changes in neural substrates underlying positive and negative feedback processing during goal-directed implicit learning using the Sugar Production Factory (SPF) task in conjunction with an event related functional magnetic resonance imaging. We found a significant learning-related decrease in activity of the right superior frontal gyrus (SFG) in response to positive feedback and a learning-related increase in activity of the precuneus in response to negative feedback. The results demonstrate the changing role of feedback during learning and suggest that learning-related changes in activity of the SFG and precuneus that have been previously reported in several implicit learning studies arise from changes in feedback processing after learning. In addition, the results suggest the important role of positive feedback in early stage and negative feedback in late stage of goal-directed implicit learning.

The Long-Term Effect of Implicit and Explicit Corrective Feedback on Accuracy of EFL Learners’ Descriptive Writing Skill
Since the emergence of the process-oriented approach to second language writing instruction two main questions have been what and how error feedback should be given to the students. The question of whether teachers should provide feedback on grammar in the writing assignments of English as a foreign language students, and if so how, has been a matter of considerable debate in the field of secon...

Thermal processing of the key lime juice leads to the inactivation of pectin methylesterase (PME) and the degradation of ascorbic acid (AA). These changes affect directly the cloud stability and color of the juice. In this study, an artificial neural network (ANN) model was applied for designing and developing an intelligent system for prediction of the thermal processing effects on the physico...

The effect of error feedback on the accuracy of output task types such as editing task, text reconstruction task, picture cued writing task, and dictogloss task, has not been clearly explored. Following arguments concerning that the combination of both corrective feedback and output makes it difficult to determine whether their effects were in combination or alone, the purpose of the present st...
متن کاملThe Effects of Direct Corrective Feedback and Metalinguistic Explanation on EFL Learners’ Implicit and Explicit Knowledge of English Definite and Indefinite Articles
This study investigated the effects of two types of written feedback – direct corrective feedback (DCF) and metalinguistic explanation (ME) - on Iranian EFL learners’ implicit and explicit knowledge of English definite and indefinite articles. Assigned to three groups of DCF, ME, and control groups, the participants took four tests in three testing phases: pretest, posttest, and delayed posttes...
