Little is known about how the brain computes the perceived aesthetic value of complex stimuli such as visual art. Here, we used computational methods in combination with functional neuroimaging to provide evidence that the aesthetic value of a visual stimulus is computed in a hierarchical manner via a weighted integration over both low and high lev...

It has been suggested that there are two distinct and parallel mechanisms for controlling instrumental behavior in mammals: goal-directed actions and habits. To gain an understanding of how these two systems interact to control behavior, it is essential to characterize the mechanisms by which the balance between these systems is influenced by exper...

... Yet, space is not the only dimension across which efficient integration can mediate perceived beauty. For example, a recent study used DNN models to quantify the integration of visual features across hierarchical levels to model aesthetic perception, and has in turn linked such hierarchical integration processes to parietal and frontal brain systems (Iigaya et al., 2023). Future studies could also link perceived beauty to integration across time: Recent studies in neuroaesthetics increasingly focus on more naturalistic and dynamic . ...
... However, with extended training, those actions become increasingly more automatic (i. e., habitual; see de Wit and Dickinson, 2009, but see de Pool et al., 2022 for recent discussions on how overtraining affects the formation of habit-like behaviors). Thus, certain stimuli trigger automatic responses regardless of the value of that stimulus (Balleine and O'Doherty, 2010). ...
... In the present studies, we also investigated the effect of behavioral repetition on test performance. Despite several attempts, experimental investigations of habit formation in humans have failed to provide convincing evidence for the development of behavioral autonomy as a function of behavioral repetition during training Pool et al., 2021;Tricomi et al., 2009). Although there are recent suggestions that participants are slower to make novel responses in the presence of stimuli that have been overtrained with a different response (Hardwick et al., 2019;Luque et al., 2020), participants rarely make more overt 'slips of action' (commission errors) for long-trained relative to short-trained devalued outcomes, in classical outcome devaluation tasks . ...
