“…Especially when combined with M-USE’s flexible I/O connectivity, these features sets the platform apart from other experimental suites that leverage various 3D and gaming capabilities in experimental design (e.g. Bebko & Troje, 2020; Bovo et al, 2022; Brookes et al, 2018; Doucet et al, 2016; Jangraw et al, 2014; Razavi et al, 2022; Schuetz et al, 2023; Watson et al, 2019b; Cutone & Wilcox, 2021).…”

BackgroundUnderstanding the neurobiological substrates of psychiatric disorders requires comprehensive evaluations of cognitive and motivational functions in preclinical research settings. The translational validity of such evaluations will be supported by (1) tasks with high construct validity that are engaging and easy to teach to human and nonhuman participants, (2) software that enables efficient switching between multiple tasks in single sessions, (3) software that supports tasks across a broad range of physical experimental setups, and (4) by platform architectures that are easily extendable and customizable to encourage future optimization and development.New MethodWe describe theMulti-task Universal Suite for Experiments(M-USE), a software platform designed to meet these requirements. It leverages the Unity video game engine and C# programming language to (1) support immersive and engaging tasks for humans and nonhuman primates, (2) allow experimenters or participants to switch between multiple tasks within-session, (3) generate builds that function across computers, tablets, and websites, and (4) is freely available online with documentation and tutorials for users and developers. M-USE includes a task library with seven pre-existing tasks assessing cognitive and motivational constructs of perception, attention, working memory, cognitive flexibility, motivational and affective self-control, relational long-term memory, and visuo-spatial problem solving.ResultsM-USE was used to test NHPs on up to six tasks per session, all available as part of the Task Library, and to extract performance metrics for all major cognitive and motivational constructs spanning the Research Domain Criteria (RDoC) of the National Institutes of Mental Health.Comparison with Existing MethodsOther experiment design and control systems exist, but do not provide the full range of features available in M-USE, including a pre-existing task library for cross-species assessments; the ability to switch seamlessly between tasks in individual sessions; cross-platform build capabilities; license-free availability; and its leveraging of video-engine capabilities used to gamify tasks.ConclusionsThe new multi-task platform facilitates cross-species translational research for understanding the neurobiological substrates of higher cognitive and motivational functions.

“…Recent technological progress has enabled the eye-tracking of dyads and groups without disrupting their complex exchange of communicative signals. For example, software innovations now automate calibration (e.g., Kassner et al, 2014 ), synchronize data from multiple devices (e.g., openSync; Razavi et al, 2022 ) and simplify the analysis of eye-tracking data collected in naturalistic settings (e.g., iMotions, 2022 ). These breakthroughs streamline device setup, eliminate the need for intrusive recalibrations, and facilitate analysis of gaze and pupil data in real-time.…”

The human eye is a rich source of information about where, when, and how we attend. Our gaze paths indicate where and what captures our attention, while changes in pupil size can signal surprise, revealing our expectations. Similarly, the pattern of our blinks suggests levels of alertness and when our attention shifts between external engagement and internal thought. During interactions with others, these cues reveal how we coordinate and share our mental states. To leverage these insights effectively, we need accurate, timely methods to observe these cues as they naturally unfold. Advances in eye-tracking technology now enable real-time observation of these cues, shedding light on mutual cognitive processes that foster shared understanding, collaborative thought, and social connection. This brief review highlights these advances and the new opportunities they present for future research.
