Abstract

Aim: The aim of the study was to find out the effects of perceptual and contextual enrichment on visual confrontation naming in young and older adults.

Method: A total of 80 participants, 40 younger adults and 40 older adults (20 males and 20 females in each group) were selected for the present study. Boston naming test materials were used to obtain the visual confrontation naming in young and older adults.

Results and Discussion: There was a significant difference between young and older adults in line pictures and there was no significant effect observed for perceptual and contextual enrichments.

Summary and Conclusion: Significant correlation elicited between the reaction time and accuracy of response only in line pictures but there was no significant correlation between reaction time and accuracy of response for perceptual and contextual enrichments. Hence, it suggests that reaction time and accuracy of response were not dependent on each other. Thus, it indicative that age and gender are plays a critical or major role in visual confrontation naming.

Keywords: Perceptual Enrichment, Contextual Enrichment, Confrontation Naming.

Introduction

Confrontation naming is a complex process involving few stages. In first stage (perceptual), following the presentation of a picture, the pictorial image is analyzed for correct identification of the stimulus. In middle stage (semantic), the information is transmitted, where its semantic representation is activated. In final stage (label retrieval), the phonological representation corresponding to the semantic representation is retrieved (Toshiko, Yoko, Hisako & Sumiko, 1990).

Processing of visual confrontation naming occurs at higher level, the parietal lobe receives new visual information, this visual data is fired to the visual cortex where symbols are recognized and organized, and this organized visual data is sent to the inferior parietal lobe where sounds connect to the letters. The sound or letter blends are fired to the superior parietal lobe where speech patterns are pre-organized and fired to the oral language center in the left temporal lobe. The Broca’s area further organized the speech material. This refined speech material is then fired to the Wernicke’s region, which puts the final touch on spoken stimuli, the speech organs are triggered to say what the eyes have seen on the page (Shaywitz, 1996).
