The brain as target image detector : the role of image category and presentation time
conference paper
The brain can be very proficient in classifying images that are hard for computer algorithms to deal with. Previous studies show that EEG can contribute to sorting shortly presented images in targets and non-targets. We examine how EEG and classification performance are affected by image presentation time and the kind of target: humans (a familiar category) or kangaroos (unfamiliar). Humans are much easier detected as indicated by behavioral data, EEG and classifier performance. Presentation of humans is reflected in the EEG even if observers were attending to kangaroos. In general, 50ms presentation time decreased markers of detection compared to 100ms. © 2011 Springer-Verlag.
In een plaatjesclassificatie BCI (Brain-computer interface) wordne hersensignalen gebruikt om doelen te onderscheiden van niet-doelen bij zeer kort gepresenteerde plaatjes. Presentatietijd en doeltype blijken een rol te spelen.
