My research is predominantly focused around the investigation of effect of caffeine and tiredness on the tip-of-the-tongue state (TOT). Although this is a common word retrieval failure in us all, at the pathological level, word finding difficulties are seen in sufferers of Alzheimer's disease and some aphasia patients. Therefore, investigations of the brain basis of the TOT state is crucial. I will be examining if TOT resolution improves with the consumption of caffeine, alongside phonological priming. And whether it is attributed to the adenosine mimicking properties of caffeine, which in result reduces the release of stimulatory neurotransmitters, improving wakefulness, vigilance and motor activities.
