    Description

    This dataset presented results from psychophysics and modeling that supports the use of image statistics heuristics in the judgement of metallicity. To investigate visual features associated with the interpretation of metallic objects, five practiced participants (aged 23 to 28 years old) with normal color vision and normal or corrected-to-normal visual acuity were recruited to perform a conjoint-measurement...

    Description

    This study investigated how psychophysical reverse correlation may be used to understand the sensory mechanisms and decision-making processes underlying goal-directed behavior. The investigators used simulation modeling to build variations of a drift diffusion model (DDM) to develop a quantitative measure of psychophysical kernels on the integration of sensory input over time (non-decision time) until...
