Abstract
In this presentation, I will discuss a paradigm we have developed to look at recognition-induced forgetting of visual objects. Recognition-induced forgetting occurs when practice recognizing an object, from a group objects learned at the same time, leads to worse memory for objects from that group that were not practiced. This forgetting effect is commonly accompanied by improved memory for practiced objects. We have shown that recognition-induced forgetting is not an artifact of category-based set size. I will discuss our developmental work showing this forgetting effect comes online by 6 years of age without a memory benefit for practiced objects until 9 years of age. Further, the forgetting appears to remain robust with healthy aging in samples of older adults, without the benefit for practiced objects shown in young adults but accompanied by a decrease in intrusion errors. I will conclude by discussing our use of this paradigm to understand how this forgetting phenomenon operates on temporally clustered objects and stimuli of expertise, as well as our technique of using cathodal transcranial direct-current stimulation to DLPFC to examine the role of inhibitory mechanisms in this forgetting phenomenon.
