Heterogenous population coding of a short-term memory and decision task.
We examined neural spike recordings from prefrontal cortex (PFC) while monkeys performed a delayed somatosensory discrimination task. In general, PFC neurons displayed great heterogeneity in response to the task. That is, although individual cells spiked reliably in response to task variables from trial-to-trial, each cell had idiosyncratic combinations of response properties. Despite the great...
متن کاملthe effects of keyword and context methods on pronunciation and receptive/ productive vocabulary of low-intermediate iranian efl learners: short-term and long-term memory in focus
از گذشته تا کنون، تحقیقات بسیاری صورت گرفته است که همگی به گونه ای بر مثمر ثمر بودن استفاده از استراتژی های یادگیری لغت در یک زبان بیگانه اذعان داشته اند. این تحقیق به بررسی تاثیر دو روش مختلف آموزش واژگان انگلیسی (کلیدی و بافتی) بر تلفظ و دانش لغوی فراگیران ایرانی زیر متوسط زبان انگلیسی و بر ماندگاری آن در حافظه می پردازد. به این منظور، تعداد شصت نفر از زبان آموزان ایرانی هشت تا چهارده ساله با...
15 صفحه اولNeural Field Coding of Short Term Memory
Short term memory (STM) is the ability of the brain to maintain a perceived stimulus even after the stimulus has disappeared. STM is assumed to be implemented in the sustained activity observed in the prefrontal cortex (PFC) during diverse tasks, like visual memory, object labelling, identity or other cognitive tasks. We here suggest that this activity can be explained as the result of changes ...
متن کاملFalse memory in a short-term memory task.
The Deese/Roediger-McDermott (DRM; Roediger & McDermott, 1995) paradigm reliably elicits false memories for critical nonpresented words in recognition tasks. The present studies used a Sternberg (1966) task with DRM lists to determine whether false memories occur in short-term memory tasks and to assess the contribution of latency data in the measurement of false memories. Subjects studied thre...
متن کاملCoding Position in Short-term Memory
Many formal models of short-term memory have recently been proposed (e.g. Anderson & Matessa, 1997; Brown, Preece, & Hulme, in press; Burgess & Hitch, 1992; Henson, 1998; Lee & Estes, 1981; Lewandowsky & Murdock, 1989; Murdock, 1995; Nairne, Neath, Serra, & Byun, 1997; Neath, 1993; Page & Norris, 1998). An important issue addressed by these models is the problem of serial order: that is, how pe...
