Phenomena in a variety of verbal tasks, e.g., masked priming, lexical decision, and word naming, are typically explained in terms of similarity between word-forms. Despite the apparent commonalities between these sets of phenomena, the representations and similarity measures used to account for them are not often related. To show how this gap might be(More)
Experiments were conducted to test a modern exemplar-familiarity model on its ability to account for both short-term and long-term probe recognition within the same memory-search paradigm. Also, making connections to the literature on attention and visual search, the model was used to interpret differences in probe-recognition performance across diverse(More)
Models of recognition memory have traditionally struggled with the puzzle of criterion setting, a problem that is particularly acute in cases in which items for study and test are of widely varying types, with differing degrees of baseline familiarity and experience (e.g., words vs. random dot patterns). We present a dynamic model of the recognition process(More)
Many measures of human verbal behavior deal primarily with semantics (e.g., associative priming, semantic priming). Other measures are tied more closely to orthography (e.g., lexical decision time, visual word-form priming). Semantics and orthography are thus often studied and modeled separately. However, given that concepts must be built upon a foundation(More)
A fundamental distinction in tasks of memory search is whether items receive varied mappings (targets and distractors switch roles across trials) or consistent mappings (targets and distractors never switch roles). The type of mapping often produces markedly different performance patterns, but formal memory-based models that account quantitatively for(More)
Inspired by a dynamic approach to recognition memory (Cox & Shiffrin, 2012), we present results from a recognition memory experiment in which the time at which diagnostic information arrives is unconsciously varied. Contrary to the predictions of most models, performance improves when diagnostic information is available later, rather than earlier. These(More)
Many people have had the experience of knowing what song will play next on an album (even one heard only a few times). Conversely, many people fail to recognize an acquaintance encountered in an unfamiliar context. Associations can likely form simply because items appear nearby in time, and not only due to semantic similarity. Using surprise recognition(More)
Associative recognition—the ability to discriminate between studied and novel associations—has been attributed to the operation of a recall-like process that is not engaged during recognition of single items. An alternative mechanism for as-sociative recognition is the formation of a compound memory cue that incorporates relational information between the(More)
Cognitive scientists have begun collecting the trajectories of hand movements as participants make decisions in experiments. These response trajectories offer a fine-grained glimpse into ongoing cognitive processes. For example, difficult decisions show more hesitation and deflection from the optimal path than easy decisions. However, many summary(More)
