Neuroimaging Findings for the Overnight Consolidation of Learned Non-native Speech Sounds.

Research over the past two decades has documented the importance of sleep to language learning. Sleep has been suggested to play a role in establishing new speech representations as well; however, the neural mechanisms corresponding to sleep-mediated effects on speech perception behavior are unknown. In this study, we trained monolingual English-speaking adults to perceive differences between the Hindi dental vs.

The Role of Sleep in Memory Consolidation and Reading in Dyslexia.

Dyslexia is a neurodevelopmental disorder characterized by reading difficulty, which has long been attributed to a phonological processing deficit. However, recent research suggests that general difficulties with learning and memory, but also in memory consolidation, may underlie disordered reading. This review article provides an overview of the relationship between learning and memory, memory consolidation during sleep, and reading and explores the emerging literature on consolidation during sleep in individuals with dyslexia.

Declarative memory supports children's math skills: A longitudinal study.

Substantial progress has been made in understanding the neurocognitive underpinnings of learning math. Building on this work, it has been hypothesized that declarative and procedural memory, two domain-general learning and memory systems, play important roles in acquiring math skills. In a longitudinal study, we tested whether in fact declarative and procedural memory predict children's math skills during elementary school years.

Feedback timing-modulated weather prediction reveals relative deficits in both procedural and declarative learning in adults with dyslexia.

A topic of recent debate is the hypothesis that deficits associated with developmental disorders of language, such as reading disability, can be explained by a selective weakness in procedural memory. Adults with (n = 29; RD) and without (n = 29; TD) reading disability completed a weather prediction task under immediate and delayed feedback conditions, that rely on the striatal (procedural) and hippocampal (declarative) circuits, respectively. We examined trial-by-trial accuracy by feedback condition (immediate vs.

A Matter of Time: A Web-Based Investigation of Rest and Sleep Effects on Speech Motor Learning.

Purpose: Here, we examine the possibility that memory consolidation during a period of postpractice rest or nocturnal sleep can bolster speech motor learning in the absence of additional practice or effort.

Method: Using web-administered experiments, 74 typical, American English talkers trained in a nonnative vowel contrast then had a 12-hr delay with (SLEEP) or without nocturnal sleep (REST) or proceeded immediately (IMMEDIATE) to a posttraining production assessment. For ecological validity, 51 native Danish talkers perceptually identified the American English talkers' productions.
