However, the development and availability of new technology allow researchers to move beyond this paradigm and use other features to detect schedules. Thus, our study used spatiotemporal data to compare the accuracy of four machine learning algorithms (i.e., logistic regression, support vector classifiers, random forests, and artificial neural networks) in detecting the presence and the components of timebased schedules in 12 rats involved in a behavioral experiment. Using spatiotemporal data, the algorithms accurately identified the presence or absence of programmed schedules and correctly differentiated between fixed- and variable-space schedules. That said, our analyses failed to identify an algorithm to discriminate fixed-time from variable-time schedules. Furthermore, none of the algorithms performed systematically better than the others. Our findings provide preliminary support for the utility of using spatiotemporal data with machine learning to detect stimulus schedules.  \nKEYW ORDS  \nmachine learning, neural network, spatiotemporal data, time-based schedule  \nThe experimental analysis of behavior typically involves environments that are manipulated by an experimenter to examine the effects of changes in these environments on the behavior of living organisms (Skinner, 1966) . These experimental manipulations have contributed to the development of a comprehensive, rigorous, and conceptually systematic natural science of behavior (Catania, 2013) . By manipulating environments, researchers have extensively studied the effects of stimulus delivery and behavior-dependent schedules in both human and nonhuman organisms (Kahng & Iwata, 2005; Schlinger et al., 2008) . Traditionally, the identification of these behavioral patterns has relied on the measurement of single discrete responses. This traditional approach, known as the single discrete response paradigm (Henton & Iversen, 1978), relies on behaviors selected for their ease of measurement and applicability such as lever presses for rats, key pecks for pigeons, and screen clicks for humans. However, an organism’s behavior is not confined  \nto discrete responses in noncontrived environments. Organisms exhibit spatiotemporal continuity in their behavior, often displaying a diverse range of ecologically relevant behavioral patterns including foraging, water-seeking, and mating (Hernndez et al., 2023; Len et al., 2020, 2021) .  \nA substantial body of empirical evidence indicates thatspatiotemporal features of behavior are highly sensitive to reinforcement contingencies (Baum & Rachlin, 1969; Hernndez et al., 2023; Len et al., 2021; Silva & Timberlake, 1997; Timberlake & Lucas, 19","cbCaicMjZH0EFt18","https://ap.wps.com/l/cbCaicMjZH0EFt18","pdf",1339284,2,1,12,"English","en",105,"#
