‘Visual Evoked Potential': A Tool for Assessing Underlying Deficit in Low Academic Achievers
Journal Title: People's Journal of Scientific Research. - Year 2016, Vol 9, Issue 1
Abstract
Poor academic performance among students requires due attention. It might be a symptom reflecting an underlying physiological problem. Any problem in the visual processing of the information could be one of the contributory factors of the poor academic performance. Visual evoked potential (VEP) is a sensitive & reliable parameter to assess the functional integrity in visual pathway. Present study has investigated the relationship of poor academic performance among students with visual processing of the information. The academic scores of final examinations of preceding 2 years were assessed among 18-25 year aged college youth. These were divided under two categories namely 'high academic achievers' (>80% in 10th & 12th Board) and 'low academic achievers' (<50% in 10th & 12th Board) with 40 participants in each group. VEP was recorded by LED Goggles method in 'Octopus Clarity Machine'. In low achievers, latency of N75 and P100 were significantly prolonged. The latency of N135 showed no difference among both the groups, but the amplitude of VEP (P100-N135) was found to be significantly reduced in low achievers as compared to high achievers. Weaker VEP response in low achievers could be due to some defect in central neural processing of the visual information. Thus, VEP can be used as a tool to assess the underlying deficit in low academic achievers.
