Abstract:
Humans are constantly processing scene information from their environment to make meaningful decisions. However, it remains unknown which of the emerging neural representations are relevant for decision-making, and how we can model these representations and their link to behaviour in a unified way. Here, we approached these questions empirically and via computational modelling using deep neural networks. First, we correlated electroencephalography (EEG) data and categorization reaction times and observed a brain-behaviour correlation between ~100 ms and ~200 ms after stimulus onset. Second, to provide a model of scene categorization which integrates both neural and behavioural data, we evaluated a recurrent convolutional neural network (RCNN) and observed similarities between humans and the network in terms of neural representations, behaviour, and the brain-behaviour relationship. Altogether, our results provide an empirical and computational account of scene categorization in humans, benefiting both cognitive and computational neuroscience for future exploration and explanation of human decision-making.
