The present study investigated whether individual differences in working memory could account for a significant proportion of the variance in the open-set word recognition and receptive vocabulary skills of prelingually deafened, pediatric cochlear implant recipients, after the contribution of known predictors was taken into account. The contributions of four measures of working memory were exa...

Clinical data from brain-damaged patients implicates the human hippocampal formation in memory function. We tested the hypothesis that long-term memory function is associated with activation of the hippocampal formation in humans by measuring regional cerebral blood flow changes whilst subjects performed memory tasks. Bilateral hippocampal regional cerebral blood flow was significantly correlat...

The acquisition of auditory memory for temporal patterns was investigated. The temporal patterns were random sequences of irregularly spaced clicks. Participants performed a task previously used to study auditory memory for noise [Agus, Thorpe, and Pressnitzer (2010). Neuron 66, 610-618]. The memory for temporal patterns displayed strong similarities with the memory for noise: temporal patterns...

Memory is a constructive and organizational process. Instead of being stored with all the fine details, external information is reorganized and structured at certain spatiotemporal scales. It is well acknowledged that time plays a central role in audition by segmenting sound inputs into temporal chunks of appropriate length. However, it remains largely unknown whether critical temporal structur...

The present study investigated whether (a) a reduced duration of auditory sensory memory is found in late talking children and (b) whether deficits of sensory memory are linked to persistent difficulties in language acquisition. Former late talkers and children without delayed language development were examined at the age of 4 years and 7 months using mismatch negativity (MMN) with interstimulu...

Working memory is the cognitive capacity of short-term storage of information for goal-directed behaviors. Where and how this capacity is implemented in the brain are unresolved questions. We show that auditory cortex stores information by persistent changes of neural activity. We separated activity related to working memory from activity related to other mental processes by having humans and m...

Questions have been raised about whether poor performance on memory tasks by individuals with major depressive disorder (MDD) might be the result of poor or variable effort or disease-related disruption of neural circuits supporting memory functions. The present study examined performance on a measure of task engagement and on an auditory memory task among 45 patients with MDD (M age = 47.82, S...

Research indicates that false memory is lower following visual than auditory study, potentially because visual information is more distinctive. In the present study we tested the extent to which retrieval orientation can cause a modality effect on memory accuracy. Participants studied unrelated words in different modalities, followed by criterial recollection tests that selectively oriented ret...

The neural basis of auditory perception can be investigated non-invasively by recording event-related brain potentials (ERPs) during auditory stimulation.1 ERPs can be conceptualized as a sequence of components each with its own set of neural generators and reflecting different psychological functions.2 The ERP component termed the mismatch negativity (MMN) reflects a pre-attentive auditory dev...

Auditory sensory memory is assumed to play an important role in cognitive development, but little is known about it in young children. The aim of this study was to estimate the duration of auditory sensory memory in 2-year-old children. We recorded the mismatch negativity in response to tone stimuli presented with different interstimulus intervals. Our findings suggest that in 2-year-old childr...
