    Perceptual Dissimilarity Analysis Distinguishes Grapheme‐Color Synesthetes from Nonsynesthetes.Michelle Gravener, Simon Lacey & Krishnankutty Sathian - 2022 - Cognitive Science 46 (9):e13189.
    Synesthetes can be distinguished from nonsynesthetes on a variety of experimental tasks because their concurrent synesthetic experiences can affect task performance if these experiences match or conflict with some aspect of the stimulus. Here, we tested grapheme‐color synesthetes and nonsynesthetic control participants using a novel perceptual similarity task to assess whether synesthetes’ concurrent color experiences influence perceived grapheme similarity. Participants iteratively arranged graphemes and, separately, their associated synesthetic colors in a display, such that similar items were placed close together and (...)

    Multifaceted functional specialization of somatosensory information processing.K. Sathian, Simon Lacey, Gregory Gibson & Randall Stilla - 2007 - Behavioral and Brain Sciences 30 (2):219-220.
    We review evidence for multifaceted functional specialization of somatosensory information processing, both within and outside classical somatosensory cortex. We argue that the nature of such specialization has not yet been clarified adequately to regard the proposed action/perception dichotomy as being established. However, we believe this is a good working hypothesis that can motivate further work.

    Modality, quo vadis?K. Sathian - 2004 - Behavioral and Brain Sciences 27 (3):413-414.
    Grush's emulation theory comprises both modality-specific and amodal emulators. I suggest that the amodal variety be replaced by multisensory emulators. The key distinction is that multisensory processing retains the characteristics of individual sensory modalities, in contrast to amodal processing. The latter term is better reserved for conceptual and linguistic systems, rather than perception or emulation.

    A rigorous approach for testing the constructionist hypotheses of brain function.Gopikrishna Deshpande, K. Sathian, Xiaoping Hu & Joseph A. Buckhalt - 2012 - Behavioral and Brain Sciences 35 (3):148-149.
    Although the target article provides strong evidence against the locationist view, evidence for the constructionist view is inconclusive, because co-activation of brain regions does not necessarily imply connectivity between them. We propose a rigorous approach wherein connectivity between co-activated regions is first modeled using exploratory Granger causality, and then confirmed using dynamic causal modeling or Bayesian modeling.

    Stimulus Parameters Underlying Sound‐Symbolic Mapping of Auditory Pseudowords to Visual Shapes.Simon Lacey, Yaseen Jamal, Sara M. List, K. Sathian & Lynne C. Nygaard - 2020 - Cognitive Science 44 (9):e12883.
    Sound symbolism refers to non‐arbitrary mappings between the sounds of words and their meanings and is often studied by pairing auditory pseudowords such as “maluma” and “takete” with rounded and pointed visual shapes, respectively. However, it is unclear what auditory properties of pseudowords contribute to their perception as rounded or pointed. Here, we compared perceptual ratings of the roundedness/pointedness of large sets of pseudowords and shapes to their acoustic and visual properties using a novel application of representational similarity analysis (RSA).
