Intentional Forgetting In Students With Learning Disabilities

The study of intentional forgetting is a completely newly research paradigm. It emphasizes that it is intentional and directed and is very different from spontaneous forgetting. There are two main research methods at present: the list method and the item method. Generally, it is believed that retrieval inhibition play a very important role in the list method paradigm, so which can reveal participants'capacity on retrieval inhibition. Later researchers pointed out that the list method intentional forgetting effect is also affected by encoding. Inhibition deficits and coding capacity are two main reasons causing learning disability. In this study, we used the list method intentional forgetting paradigm to investigate the different type learning disabilities'performance in the task, trying to seek reasons for the disabilities from the field.First, the nature of the experimental material affected intentional forgetting. Secondly, different types of learning disabilities may have different sensitivity for different materials. So we designed two experiments: Chinese word intentional forgetting with learning disabilities and Arabic numerals intentional forgetting with learning disabilities. Through two experiments, the conclusions of the study were following.1. The control group, namely, the normal students in Chinese word intentional forgetting experiments appeared intentional forgetting phenomenon, but language difficulties group, mathematic disability and double-trapped group do not appear this phenomenon.2. Chinese word intentional forgetting mechanism is retrieval inhibition and encoding.3. In Chinese word intentional forgetting experiment, the students of control group, have the strongest suppression, the suppression of mathematic and reading disability students develop incompletely, and the inhibition of double-trapped group is the worst.4. The control group and the reading disability group display Arabic numerals intentional forgetting .while mathematic disability and double-trapped group don't appear this phenomenon.5. The mechanism of Arabic numerals intentional forgetting is retrieval inhibition.6. In Chinese word intentional forgetting experiment the control group and the reading disability group show a better suppression, however, the mathematic and double-trapped group are significant lack of suppression.
