A diffusion model account of the lexical decision task.
The diffusion model for 2-choice decisions (R. Ratcliff, 1978) was applied to data from lexical decision experiments in which word frequency, proportion of high- versus low-frequency words, and type of nonword were manipulated. The model gave a good account of all of the dependent variables--accuracy, correct and error response times, and their distributions--and provided a description of how t...
متن کاملA model for evidence accumulation in the lexical decision task.
We present a new model for lexical decision, REM-LD, that is based on REM theory (e.g., ). REM-LD uses a principled (i.e., Bayes' rule) decision process that simultaneously considers the diagnosticity of the evidence for the 'WORD' response and the 'NONWORD' response. The model calculates the odds ratio that the presented stimulus is a word or a nonword by averaging likelihood ratios for lexica...
متن کاملA diffusion model analysis of the effects of aging in the lexical-decision task.
The effects of aging on response time (RT) are examined in 2 lexical-decision experiments with young and older subjects (age 60-75). The results show that the older subjects were slower than the young subjects, but more accurate. R. Ratcliff s (1978) diffusion model provided a good account of RTs, their distributions, and response accuracy. The fits show an 80-100-ms slowing of the nondecision ...
متن کاملA Diffusion Model Account of Criterion Shifts in the Lexical Decision Task.
Performance in the lexical decision task is highly dependent on decision criteria. These criteria can be influenced by speed versus accuracy instructions and word/nonword proportions. Experiment 1 showed that error responses speed up relative to correct responses under instructions to respond quickly. Experiment 2 showed that that responses to less probable stimuli are slower and less accurate ...
متن کاملRunning head : LEXICAL DECISION Lexical decision and the diffusion model : An investigation into the mental lexicon
The lexical decision is one of the most widely used tasks in cognition and memory and language. The EZ diffusion model for 2-choice decisions was applied to data from lexical decision experiments in which word frequency, orthographic neighborhood size, and priming condition were manipulated. By fitting the data to parameters used to generate a random walk model, the model provides a description...
