Techniques Used: Diffusion-based Assay, Software

Diffusion-based Assay:

Article Title: A systematic exploration of temporal bisection models across sub- and supra-second duration ranges
Article Snippet: An integral component to the validity of timing models is their ability to accurately fit behavioral data from detection and discrimination tasks such as the temporal bisection procedure.. Two of the most prominent timing models are the Sample Known Exactly (SKE), based on scalar timing theory, and the pseudo-logistic model (PLM).. Recently, evidence accumulation models based on drift–diffusion processes (DDM) have been utilized for modeling temporal bisection data.

Article Title: Vicarious Rewards Modulate the Drift Rate of Evidence Accumulation From the Drift Diffusion Model
Article Snippet: .. For fitting the diffusion model to the data ( ; ), we used the MATLAB Diffusion Model Analysis Toolbox [DMAT ( )]. ..

Article Title: Autistic Traits in the Neurotypical Population do not Predict Increased Response Conservativeness in Perceptual Decision Making.
Article Snippet: .. We performed the fitting using the Diffusion Model Analysis Toolbox (DMAT; Vandekerckhove & Tuerlinckx, 2007) for MATLAB. ..

Article Title: Processing of face identity in the affective flanker task: a diffusion model analysis.
Article Snippet: Affective flanker tasks often present affective facial expressions as stimuli.. However, it is not clear whether the identity of the person on the target picture needs to be the same for the flanker stimuli or whether it is better to use pictures of different persons as flankers.. While Grose-Fifer, Rodrigues, Hoover & Zottoli (Advances in Cognitive Psychology 9(2):81–91, 2013) state that attentional focus might be captured by processing the differences between faces, i.e. the identity, and therefore use pictures of the same individual as target and flanker stimuli, Munro, Dywan, Harris, McKee, Unsal & Segalowitz (Biological Psychology, 76:31–42, 2007) propose an advantage in presenting pictures of a different individual as flankers.

Article Title: How many trials are required for parameter estimation in diffusion modeling? A comparison of different optimization criteria.
Article Snippet: .. The Diffusion Model Analysis Toolbox (DMAT; Vandekerckhove & Tuerlinckx, 2007, 2008) is a MATLAB toolbox. ..

Article Title: Qualitative speed-accuracy tradeoff effects that cannot be explained by the diffusion model under the selective influence assumption
Article Snippet: .. We fit the diffusion model to the data using both the hierarchical drift diffusion model (HDDM) python package and the diffusion model analysis toolbox (DMAT) in MATLAB . ..

Article Snippet: Behavioral responses and RTs were fitted with a drift diffusion model in MATLAB using the Diffusion Model Analysis Toolbox (DMAT) , based on ref. .

Article Title: Stimulus probability effects on temporal bisection performance of mice (Mus musculus).
Article Snippet: In the temporal bisection task, participants classify experienced stimulus durations as short or long based on their temporal similarity to previously learned reference durations.. Temporal decision making in this task should be influenced by the experienced probabilities of the reference durations for adaptiveness.. In this study, we tested the temporal bisection performance of mice (Mus musculus) under different short and long reference duration probability conditions implemented across two experimental phases.
