This dataset contains behavioral data assessing the sensitivity of five human subjects (one female and four male) to higher-order moments of motion as applied to random dot kinematograms. The dots were manipulated by probability distributions that systematically differed in their mean, variance, skewness, or kurtosis. Following training sessions where they reached at least 80% accuracy, subjects were...

The investigators collected simultaneous recordings using multi-channel electrode arrays attached to the prearcuate gyrus of macaque monkeys who performed a direction discrimination task with fixed stimulus duration. In the study, 96-channel multielectrode arrays were used to record from neural populations in area 8Ar of the prearcuate gyrus of three macaque monkeys, while they performed a direction...

This dataset assesses the influence of timescale on the processing of visual stimuli. Following training sessions where they reached at least 76% accuracy, five human subjects (four male and one female) were presented with the following task: brief samples of a contrast pattern were presented on screen for 200 ms, followed by a pause before the subjects were prompted to match the samples to one of...

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...

To investigate the relationship between two behavioral markers of arousal (pupil size and brain activity) and perceptual decision-making, recordings were simultaneously obtained on pupil size and brain activity using magnetoencephalography (MEG). Data was collected from a total of 24 adult participants during eyes-open rest sessions and a visual perceptual decision-making task. Two 5-minute rest...

The investigators recruited 14 adult patients undergoing evaluation at NYU Comprehensive Epilepsy Center prior to surgery, 24 healthy volunteers participating in-person, and 60 healthy volunteers participating online for experiments to examine the influence of long-term prior knowledge ('priors') on perception. Bistable perception task: 14 epilepsy patients who were undergoing surgical evaluation...

Social behaviors, such as mating, fighting, and parenting, are innate and supported by dedicated neural circuits. However, the molecular identities of these circuits and how they are established developmentally and shaped by experience remain unknown. This study demonstrate that medial amygdala cells originating from two embryonically parcellated developmental lineages have distinct response patterns...

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...
