Is phonological learning subject to the same inductive biases as learning in other domains? Previous studies of non-linguistic learning found that intra-dimensional dependencies (between two instances of the same feature) were learned more easily than inter-dimensional ones. This study compares implicit learning of intra- and inter-dimensional…

Dual-process models differentiate between two bases of memory, recollection and familiarity. It is routinely claimed that deeper, semantic encoding enhances recollection relative to shallow, non-semantic encoding, and that recollection is largely a product of semantic, elaborative rehearsal. The present experiments show that this is not always the…

Normative word frequency and context variability affect memory in a range of episodic memory tasks and place constraints on theoretical development. In four experiments, we independently manipulated the word frequency and context variability of the targets (to-be-generated items) and cues in a cued recall paradigm. We found that high frequency…

This study investigated whether Foygel and Dell's (2000) interactive two-step model of speech production could simulate the number and type of errors made in picture-naming by 68 children of elementary-school age. Results showed that the model provided a satisfactory simulation of the mean error profile of children aged five, six, seven, eight and…

Using the DRM paradigm, our experiments examined the activation and monitoring of memories in semantic and phonological networks. Participants viewed lists of words and/or pseudohomophones (e.g., "dreem"). In Experiment 1, participants verbally recalled lists of semantic associates or attempted to write them as they appeared during study. False…

This study presents the first direct comparison of immediate serial recall in semantic dementia (SD) and transcortical sensory aphasia (TSA). Previous studies of the effect of semantic impairment on verbal short-term memory (STM) have led to important theoretical advances. However, different conclusions have been drawn from these two groups. This…

Preschool-age children were hypothesized to use one of two criteria, cue recognition or target generation, to make several linguistic judgments. When deciding whether a word is one they know, for example, some were expected to consider whether they recognized its sound form (cue recognition), whereas others were expected to consider whether a…

The aim of the present research was to determine whether the effect that phonological similarity has on immediate serial recall is influenced by the consistency and position of phonemes within words. In comparison to phonologically dissimilar lists, when the stimulus lists rhyme there is a facilitative effect on the recall of item information and…

In the present paper, we develop and apply a technique, based on the logic of process dissociation, for obtaining numerical estimates of item and order information. Certain variables, such as phonological similarity, are widely believed to produce dissociative effects on item and order retention. However, such beliefs rest on the questionable…

Four experiments are reported exploring whether distractor pictures activate their phonological properties in the course of speech production. In Experiment 1, participants were presented with two pictures and were asked to name one while ignoring the other. Distractor pictures were phonologically related, semantically related or unrelated to the…

Single-task and dual-task versions of verbal and spatial serial order memory tasks were administered to 120 students tested for working memory capacity with four previously validated measures. In the dual-task versions, similarity between the memory material and the material of the secondary processing task was varied. With verbal material, three…
