A study from researchers at the University of Turin suggests that when people view landscape photographs they personally find beautiful, their immediate movement may be slowed and the brain’s preparation for action dampened. The findings, published in Social Cognitive and Affective Neuroscience, support the idea that aesthetic appreciation can momentarily shift brain resources away from action so attention can be devoted to absorbing sensory information.
The work situates itself within a long-running debate about how beauty affects the brain’s motor systems. Early research hinted at a link between perceived beauty and movement-related brain activity, with some studies suggesting that looking at scenes deemed ugly might provoke stronger motor responses, while others argued that art appreciation engages motor circuits through mental simulation of depicted actions.
Building on a newer framework, the researchers test what has been described as the “Stopping for Knowledge” hypothesis: that beauty signals the brain to briefly halt action so it can devote processing power to extracting information from the environment. While previous work with music hinted at slowed responses to pleasant stimuli, this study uniquely investigates how viewing preferred images alters subsequent motor preparation.
The experiments were led by Paolo Barbieri and Irene Ronga of the BraIn Plasticity and Behaviour Changes Group in the Department of Psychology at Turin, with collaborators including others who have helped develop the hypothesis. Barbieri described the aim as exploring whether aesthetic appreciation can cause a temporary decoupling between perception and action.
In the first experiment, 30 right-handed young adults viewed a set of 100 black-and-white landscape photographs, carefully standardised for brightness, contrast and size. After each image appeared for a random 5–6 seconds, participants pressed a spacebar as soon as the photo disappeared and then rated how much they liked it on a nine-point scale. On 5 per cent of trials, a static white-noise image tested attention and compliance.
Reaction-time analysis showed a subtle but consistent effect: participants were slower to press the spacebar after viewing images they liked more, taking about 297 milliseconds, versus 288 milliseconds after less-favoured photographs. The slowdown of roughly 9 milliseconds translates to around a 3.1 per cent increase in reaction time, a finding the authors describe as a medium effect within participants.
To probe the neural basis, a separate group of 20 participants underwent EEG while performing a parallel task. In this second experiment, the same landscape images were viewed four times across four blocks, but responses were cued by a coloured “traffic light” after the image vanished. In 75 per cent of trials, a green cue signalled the participant to press the spacebar promptly and rate the image; in the remaining 25 per cent, a red cue instructed them to withhold the response. The viewing time remained fixed at five seconds before the cue.
Behaviourally, the second experiment mirrored the first: the top set of preferred trials averaged a rating of 7.56 out of 9, while the bottom set averaged 3.54. Reaction times averaged 504 milliseconds after preferred images, compared with 497 milliseconds after non-preferred ones, a delay of about 7 milliseconds or roughly 1.4 per cent. The total time in this experiment was longer, about 200 milliseconds more, likely due to the added requirement of discerning the traffic-light cue.
EEG analyses focused on the readiness potential, a slow buildup of neural activity preceding voluntary movement. The researchers found that in the final moments of viewing preferred landscapes, the readiness potential was noticeably smaller than after viewing non-preferred landscapes, particularly in the window from 73 to 14 milliseconds before the cue.
Following the green cue, brain responses tied to evaluating the cue (290–470 milliseconds) and to executing the action (660–1,010 milliseconds) also showed reductions after preferred photographs. Across the dataset, trials with higher aesthetic ratings tended to exhibit weaker movement-related brain signals.
Barbieri emphasised the robustness of the trial-by-trial relationship: “Initially, I thought the effect might be driven mainly by the contrast between highly appreciated and poorly appreciated images, with intermediate ratings potentially obscuring the relationship. I was genuinely surprised to find that our brain responses were modulated so precisely and parametrically by our subjective preferences.”
Rhythmic brain activity further illustrated the pattern. About two seconds before the cue, viewing preferred landscapes produced a sharper drop in alpha power and a stronger rise in beta power, compared with non-preferred images. A second rise in beta activity occurred roughly 410–460 milliseconds after the cue, which the researchers interpret as signs of heightened visual attention paired with motor inhibition.
“My next goal is to bring together different aspects of this framework within a single experiment,” Barbieri said. “In particular, I would like to investigate whether the decoupling between perception and action is accompanied by a greater predisposition to learn from and attend to the surrounding environment.”
The researchers caution that the observed delays are small—the reaction-time differences amount to mere fractions of a second—and that the motor system is not “turned off” during aesthetic experiences. They note that participants may mentally simulate actions even as movement is inhibited, and that different art forms or real-world settings could yield different patterns.
They also acknowledge limitations: the laboratory tasks use grayscale photos on screens and small, homogeneous participant groups. Nonetheless, the team argues that the results illuminate a broader possibility—that aesthetic experiences may foster a mindset oriented toward learning and exploration by temporarily deferring immediate goals.
