Resumo
Sabe-se que a velocidade de processamento de informação visual é afetada pela ingestão de álcool, já que os consumidores excessivos têm uma menor velocidade de processamento de informação visual do que os não consumidores. O objetivo deste estudo foi o de verificar se o consumo de álcool afete a velocidade de processamento de informação visual de imagens criativas e neutras. Para estudar esta questão os participantes (consumidores de álcool e não consumidores) observaram cenários compostos por dois tipos de imagens (criativas e neutras). A amostra foi composta por 113 estudantes universitários, dos quais 97 eram consumidores de álcool e 16 eram abstinentes. Imagens criativas e não criativas foram então apresentadas num paradigma de competição. Os movimentos dos olhos foram registados continuamente com o Eye-tracker Tobii T60. Os tempos de reação, tal como o tempo total de fixação durante a apresentação de imagens foram analisados. Os resultados mostraram efeitos significativos (p> 0,05) do consumo de álcool na velocidade de processamento de informação visual. No entanto as imagens criativas foram processadas mais rapidamente do que as imagens neutras (p <0,05), com efeito de interação no sexo. Encontraram-se também diferenças significativas (p <0,05) entre as imagens criativas e as imagens neutras no tempo total de fixação.
Previous studies suggest that visual information processing speed is affected by alcohol ingestion. Some authors argue that heavy drinkers have a lower visual information processing speed than nonconsumers. The study objective was to study whether alcohol consumption differently affect visual information processing speed of creative and uncreative images. In order to study this prediction, the participants (alcohol consumers and nonconsumers) observed canary with two type of images (creative and neutral) . The study sample consisted of 113 university students, of which 97 were alcohol consumers and 16 were nonconsumers. Creative and uncreative images were presented in a competition design. Eye movements were continuously monitored with a Tobii T60 eye-tracker. Reaction times, along with total time fixation during picture presentation were analysed. The results showed no significant effects (p > 0.05) of alcohol consumption on visual information processing. However, creative images were processed faster than uncreative (p < 0.05) with interaction effect on gender. There were also significant differences (p < 0.05) between creative and uncreative images in total fixation time.
