Abstract
Multilevel modeling provides the ability to simultaneously evaluate the discounting of individuals and groups using indifference point data. After considering the conditions when weaknesses emerge in estimating individual discounting as a prelude to estimating group discounting, examples are provided that indicate that multilevel modeling improves estimation in the presence of variability and missing data, and when trying to fit two-parameter discounting functions. Concrete examples of how to fit nonlinear multilevel models are provided to help researchers in the adoption of these methods.

Applying mixed-effects modeling to single-subject designs: An introduction

TL;DR: The results of a generalized linear mixed-effects model applied to single-subject data taken from Ackerlund Brandt, Dozier, Juanico, Laudont, & Mick, 2015, in which children chose from one of three reinforcers for completing a task are presented.

Anhedonia in Trauma-Exposed Individuals: Functional Connectivity and Decision-Making Correlates.

TL;DR: Greater anhedonia was related to higher positive connectivity between NAcc and right dorsomedial prefrontal cortex and to increased delay discounting, i.e., greater preference for smaller immediate versus larger delayed rewards.

Durability and generalizability of time-based intervention effects on impulsive choice in rats.

TL;DR: The experiments indicate that the FI intervention is effective at decreasing impulsive choice behavior for an extended period across changing delays and magnitudes, suggesting a relatively broad effect on choice behavior.

Applying Mixed-Effects Modeling to Behavioral Economic Demand: An Introduction

TL;DR: A high-level overview of mixed-effects modeling techniques applied to behavioral economic demand data can be found in this article, where the authors compare and contrast results from traditional techniques to that of the mixed effects models across two datasets differing in species and experimental design.

Estimating the reproducibility of psychological science

Alexander A. Aarts, +290 more
- 28 Aug 2015 - 
TL;DR: A large-scale assessment suggests that experimental reproducibility in psychology leaves a lot to be desired, and correlational tests suggest that replication success was better predicted by the strength of original evidence than by characteristics of the original and replication teams.

False-Positive Psychology: Undisclosed Flexibility in Data Collection and Analysis Allows Presenting Anything as Significant

TL;DR: It is shown that despite empirical psychologists’ nominal endorsement of a low rate of false-positive findings, flexibility in data collection, analysis, and reporting dramatically increases actual false- positive rates, and a simple, low-cost, and straightforwardly effective disclosure-based solution is suggested.

A discounting framework for choice with delayed and probabilistic rewards.

TL;DR: The present effort illustrates the value of studying choice involving both delayed and probabilistic outcomes within a general discounting framework that uses similar experimental procedures and a common analytical approach.

Area under the curve as a measure of discounting

TL;DR: A novel approach to the measurement of discounting based on calculating the area under the empirical discounting function, which avoids some of the problems associated with measures based on estimates of the parameters of theoretical discounting functions.
