Disruption of immediate memory and brain processes: an auditory ERP protocol.
An event-related potential (ERP) protocol is described that can be used to investigate those sound-evoked neural processes that may be implicated in disrupting immediate memory. Conventional electroencephalogram (EEG) is recorded during the performance of a task that involves ignoring irrelevant sounds while trying to hold in memory lists of numbers. Specific bioelectric measures are made to pr...
متن کاملImmediate Auditory Repetition of Words and Nonwords: An ERP Study of Lexical and Sublexical Processing
ERPs were elicited to (1) words, (2) pseudowords derived from these words, and (3) nonwords with no lexical neighbors, in a task involving listening to immediately repeated auditory stimuli. There was a significant early (P200) effect of phonotactic probability in the first auditory presentation, which discriminated words and pseudowords from nonwords; and a significant somewhat later (N400) ef...
متن کاملN 1 and the mismatch negativity are spatiotemporally distinct ERP components : Disruption of immediate memory by auditory distraction can be related to N 1 TOM
Event-related potentials (ERPs) were recorded for ignored tones presented during the retention interval of a delayed serial recall task. Themismatch negativity (MMN) andN1ERP components weremeasured to discern spatiotemporal and functional properties of their generation. A nine-token sequence with nine different tone pitches was more disruptive than an oddball (two-token) sequence, yet this odd...
متن کاملInterference processes in monkey auditory list memory
This article addresses two venerable issues in the study of memory. One is the shape of the bow-shaped serial position curve and how to explain it (e.g., Nipher, 1876; Ward, 1937). The second issue is the waxing and waning of interference processes in memory over time (Barnes & Underwood, 1959; Melton & von Lackum, 1941). We suggest that these phenomena are related and that processes of interfe...
متن کاملInterference processes in monkey auditory list memory.
A rhesus monkey's memory was tested for single items and four-item lists of natural and environmental sounds. Memory items were presented from a center speaker, followed by a retention delay and then a choice response to a test sound presented simultaneously from two side speakers. Recognition of the last item of four-item lists was much poorer than that of single items at 0-, 1-, and 2-sec del...
