The Shimojo Psychophysics Laboratory is one of the few laboratories on the campus of the California Institute of Technology which exclusively concentrates on the study of perception, cognition, and action in humans. Our lab employs psychophysical paradigms and a variety of recording techniques such as eye-tracking, functional magnetic resonance imaging (fMRI), electroencephalogram (EEG), as well as, brain stimulation techniques such as transcranial magnetic stimulation (TMS), transcranial direct current stimulation (tDCS), and recently ultrasound neuromodulation (UNM). We try to bridge the gap between cognitive and neurosciences. We would like to understand how the brain adapts real-world constraints to resolve perceptual ambiguity and to reach ecologically valid, unique solutions. In addition to our continuing interest in surface representation, motion perception, attention, and action, we also focus on crossmodal integration (including VR environments), visual preference/attractiveness decision, social brain, flow and choke in the game-playing brains, individual differences related to “neural, dynamic fingerprint” of the brain.

- Drs. Hung, Wu, and Prof. Shimojo’s aging study with Prof. Arakaki from the Huntington Medical Research Institutes have been published (here). This study found that stronger implicit interference occurred in older participants with a higher risk of developing Alzheimer’s. The study is featured on Caltech News (here).
- We are recruiting a postdoc for an interdisciplinary and internationally joint project supported by Caltech Chen Institute of Neuroscience, on human magnetoreception in relation to language. Check here.
- Dr. Shehata and Prof. Shimojo’s study with various collaborators on the neural correlates of Team Flow has been published in eNeuro (check the journal article here). The paper received a wide news coverage including The Times Magazine London (here), Psychology Today (here and here), IFL Science (here), TVN (here), Science Alert (here), SciShow News (here), and more (here). According to Altermetrics (here), the paper received a High Attention Score compared to any paper of the same age (99th percentile) and one of the highest-scoring papers ever published in eNeuro (#6 of out of 1,839).
There is a new package (here) of auditory-visual demos is now available (However, it is download-purpose only, the demos won’t work remotely).
- The highly controversial paper by Prof. Shimojo (together with Drs. H-I. Liao and M. Kashino of NTT) is finally accepted, via new peer-review system at Journal of Cognitive Neuroscience. It can be read at bioRxiv. It reports pupil constriction, rather than dilation as long-believed in the literature, to attractiveness of face. Moreover, it demonstrates a possibility of positive loop between pupil and attractiveness, just as in the case of the “gaze cascade effect” (Shimojo, et al., Nat.Neurosci., 2003).Liao, Hsin-I, Kashino, M., and Shimojo, S. Transient pupil constriction reflects and affects facial attractiveness, J. Cognitive Neurosci., in press, bioRxiv, doi: 10.1101/2020.04.02.021436.
Prof. Shimojo translated one of his journalistic articles published earlier into English. It is inspired by a recent politico-scientific Much Ado related to COVID-19 in Japan. Click here. He may translate more later.
