“…For less expert viewers, advice from experts is highly influential. Thus, there may be a strong effect of social influence on perception in this setting (Asch, 1956; Mojzisch and Krug, 2008). …”

The expertise of others is a major social influence on our everyday decisions and actions. Many viewers of art, whether expert or naïve, are convinced that the full esthetic appreciation of an artwork depends upon the assurance that the work is genuine rather than fake. Rembrandt portraits provide an interesting image set for testing this idea, as there is a large number of them and recent scholarship has determined that quite a few fakes and copies exist. Use of this image set allowed us to separate the brain’s response to images of genuine and fake pictures from the brain’s response to external advice about the authenticity of the paintings. Using functional magnetic resonance imaging, viewing of artworks assigned as “copy,” rather than “authentic,” evoked stronger responses in frontopolar cortex (FPC), and right precuneus, regardless of whether the portrait was actually genuine. Advice about authenticity had no direct effect on the cortical visual areas responsive to the paintings, but there was a significant psycho-physiological interaction between the FPC and the lateral occipital area, which suggests that these visual areas may be modulated by FPC. We propose that the activation of brain networks rather than a single cortical area in this paradigm supports the art scholars’ view that esthetic judgments are multi-faceted and multi-dimensional in nature.

“…An alternative mechanism would be conformity to the opinions of others operating solely at the decision level. Several studies have supported a model of social influence in which changes in sensory processing and perception contribute to biases of perceptual decisions under social influence—at least in adults (3–7). Here, we employ a widely used perceptual decision task involving the discrimination of 3D-motion figures and examine this model in children who follow typical and atypical developmental trajectories.…”

SignificanceSocial influence biases even simple perceptual decisions across a range of contexts. The development and mechanism of such biases remain unclear. We systematically examined the developmental course of social influence bias exerted by another person on perceptual decisions in children between 6 and 14 years old. To probe underlying mechanisms, we applied the computational model drift diffusion to behavioral response data. Our results show that although young neurotypical children seem to be unaffected by social influence, adolescents develop a systematic bias of their responses in the direction of social influence and appear to do so by integrating social information into visual perceptual processing. The same pattern of results did not emerge in age-matched autistic children, suggesting a different developmental trajectory.

“…The authors concluded that social influence can bias early perceptual processing. However, this conclusion is premature, since the activity in this network cannot solely be related to early perceptual changes but could also be due to later decisional processes (Gold and Shadlen, 2007;Mojzisch and Krug, 2008).…”

Hundreds of studies have found that humans' decisions are strongly influenced by the opinions of others, even when making simple perceptual decisions. In this study, we aimed to clarify whether this effect can be explained by social influence biasing (early) perceptual processes. We employed stimulus evoked potentials, lateralized readiness potentials (LRPs) and a diffusion model analysis of reaction time data to uncover the neurocognitive processes underlying social conformity in perceptual decision-making. The diffusion model analysis showed that social conformity was due to a biased uptake of stimulus information and accompanied by more careful stimulus processing. As indicated by larger N1-amplitudes, social influence increased early attentional resources for stimulus identification and discrimination. Furthermore, LRP analyses revealed that stimulus processing was biased even in cases of non-conformity. In conclusion, our results suggest that the opinion of others can cause individuals to selectively process stimulus information supporting this opinion, thereby inducing social conformity. This effect is present even when individuals do not blindly follow the majority but rather carefully process stimulus information.
