The 2-high-threshold (2HT) model of recognition memory assumes that test items result in distinct internal states: they are either detected or not, and the probability of responding at a particular confidence level that an item is "old" or "new" depends on the state-response mapping parameters. The mapping parameters are…

Plural phrases are open to many interpretations in English, where cumulative interpretations of noun and verb phrases are possible without any disambiguating morphology. A sentence like "Every week, the high school kids went to the movies or the ballgame" might involve quantifying over multiple occurrences of a single scenario, in which…

We tested the dual process and unequal variance signal detection models by jointly modeling recognition and source confidence ratings. The 2 approaches make unique predictions for the slope of the recognition memory zROC function for items with correct versus incorrect source decisions. The standard bivariate Gaussian version of the unequal…
