History[ edit ] Early research of bilingual lexical access was generated from the theories of unilingual lexical access.

A study of phonological processing in word recognition and its role in life

One area in this region, also commonly referred to as the visual word form area, has been shown to activate selectively for letters.

To verify this, some studies have trained adults on a new writing system and scanned them pre and post training to see the effects on the occipitotemporal region. The results have been mixed, and complicated by the fact that adults already know a writing system.

It would be simpler and more relevant to look at a training effect in children, and that is what Brem and colleagues did.

They trained prereading kindergarteners on letters and found that sensitivity to words developed in the occipitotemporal cortex. The children in this experiment trained on a computerized grapheme-phoneme correspondence game that taught them the sounds associated with individual letters.

As a control, they also trained on a nonlinguistic number-knowledge game.

Introduction

The participants did eight weeks on each game, with half the group doing the grapheme training first and the other half doing the number training first. This resulted in a nice within-subject control. They were presented with either spoken or written words, false fonts, or unintelligible speech and simply had to say whether the stimulus was in the visual or auditory modality.

After grapheme-phoneme training, kids showed increased activation to words as compared to false fonts in the left occipitotemporal region. This region is posterior to what is usually reported as the adult visual word form area.

It would be interesting to see if the region shifts with age. One of the ERP componentsthe N1 peak, was stronger in response to words after training. The source of the N1 localized to the left occipitotemporal region, right cuneus, and posterior cingulate. This is a nice study because we can see word expertise development in action, in the age group in which it presumably happens in real life.

Apparently, previous studies with primarily visual training have not increased activation in the fusiform gyrus, while training adults on phoneme grapheme mapping did. The 4th ROI from the front showed this effect.

Brain sensitivity to print emerges when children learn letter-speech sound correspondences.A word memorized in its entirety is called a sight word. Otherwise, every word we read or write would have to be sounded out, meaning that reading and writing would take a .

This article defines phonological awareness and discusses historic and contemporary research findings regarding its relation to early reading. For example, vocabulary knowledge contributes directly to growth in word recognition, 2,3 and later in the school years, skill in word recognition predicts the rate of vocabulary growth.
