![]() These two predictions are impossible to obtain for existing ACT-R one-phase parallel model of recognition memory. The model aptly simulates steep decrease in accuracy as well as steep increase in latency for responses to five most recent stimuli, and shorter latencies of accurate negative responses than latencies of positive responses to less recent stimuli. ![]() If the result of scanning is negative, the second phase – standard parallel chunk retrieval from ACT-R declarative memory – occurs with certain probability. In the first one, goal buffer is scanned serially. The model implements an idea of WM focus of attention: due to updating process a few items may be actively kept and easily accessed in ACT-R goal buffer. ![]() The paper presents proposal of a new ACT-R model of working memory (WM) search process, explaining both 'serial-like' and 'parallel-like' modes of processing observed in this task.
