The impact of energy drinks and their ingredients on cognitive functioning has been of considerable scientific interest in recent years; however studies investigating cognitive effects of energy drink consumption have centred on the postprandial impact, that is the influence of their ingredients once absorbed into the blood. It is possible however, that sensory perception of these drinks, or their ingredients can influence cognition.The four studies outlined in this thesis aim to examine the influences of sensory perception of energy drinks in human volunteers and compare these with the effects observed in the postprandial period on a range of cognitive tasks.Postprandially energy drink treatments were observed to reduce reaction times and improve accuracy compared with a placebo control in a saccadic peripheral conflict task when a 200ms gap was present between a pre stimulus cue and the stimulus; however when this gap was absent accuracy decreased, suggesting treatment had affected information processing and decision making processes. Sensory perception of a non carbonated energy drink was observed to improve reaction time and accuracy in a manual choice reaction time task irrespective of gap presence, however an artificially sweetened placebo energy drink had similar effects, but only when the pre stimulus gap was present.This thesis demonstrates that energy drinks can influence behavioural performance not only by increasing plasma glucose and caffeine levels in the postprandial period, but also through chemosensory perception, an effect elicited by the reward value of taste and flavour perception which is perhaps related to the calorific content of carbohydrates..
Too often our attention is focused on other things, but we also celebrate the arts, including music, here. Ferko presented a plaque to Sophia Hubinon that calls attention to the late musician’s “accomplishments for his love of music and his gifts to the entertainment world. A framed portrait of Hubinon, presented to the school district by his stepmother, also was dedicated and is now on permanent display in the main lobby of the school.

Largely dry in the west, but isolated snow showers remain possible across eastern areas.”Chief Meteorologist Steve Ramsdale, said earlier this week: “With cold air across all of the UK any precipitation will fall as snow. Snow showers will continue to feed into eastern parts through the week.
