Statistical Analysis of FMRI Data
Autor: F. Gregory Ashby
An overview of statistical methods for analyzing data from fMRI experiments.Functional magnetic resonance imaging (fMRI), which allows researchers to observe neural activity in the human brain noninvasively, has revolutionized the scientific study of

A general recognition theory model for identifying an ideal stimulus
Autor: Jeffrey B, Inglis, James, Bird, F Gregory, Ashby
Publikováno v: Attention, Perception, & Psychophysics. 84:2408-2421
A probabilistic, multidimensional model is described that accounts for sensory and hedonic ratings that are collected from the same experiment. The model combines a general recognition theory model of the sensory ratings with Coombs’ unfolding mode

Linear separability, irrelevant variability, and categorization difficulty
Autor: Luke A. Rosedahl, F. Gregory Ashby
Publikováno v: J Exp Psychol Learn Mem Cogn
In rule-based (RB) category-learning tasks, the optimal strategy is a simple explicit rule, whereas in information-integration (II) tasks, the optimal strategy is impossible to describe verbally. This study investigates the effects of two different c

Linking signal detection theory and encoding models to reveal independent neural representations from neuroimaging data.
Autor: Fabian A Soto, Lauren E Vucovich, F Gregory Ashby
Publikováno v: PLoS Computational Biology, Vol 14, Iss 10, p e1006470 (2018)
Many research questions in visual perception involve determining whether stimulus properties are represented and processed independently. In visual neuroscience, there is great interest in determining whether important object dimensions are represent

When instructions don't help: Knowing the optimal strategy facilitates rule-based but not information-integration category learning
Autor: F. Gregory Ashby, Luke A. Rosedahl, Raina Serota
Publikováno v: Journal of Experimental Psychology: Human Perception and Performance. 47:1226-1236
Providing verbal or written instructions on how to perform optimally in a task is one of the most common ways to teach beginners. This practice is so widely accepted that scholarship primarily focuses on how to provide instructions, not whether these

Testing Separability and Independence of Perceptual Dimensions with General Recognition Theory: A Tutorial and New R Package (grtools)
Autor: Fabian A. Soto, Emily Zheng, Johnny Fonseca, F. Gregory Ashby
Publikováno v: Frontiers in Psychology, Vol 8 (2017)
Determining whether perceptual properties are processed independently is an important goal in perceptual science, and tools to test independence should be widely available to experimental researchers. The best analytical tools to test for perceptual
