Brain Imaging01:14

Brain Imaging

Brain imaging technologies provide critical insights into both the structure and function of the human brain, enabling medical professionals and researchers to diagnose, study, and treat neurological disorders or psychiatric disorders more effectively.
These technologies include computerized axial tomography (CAT or CT scans), positron-emission tomography (PET scans),  magnetic resonance imaging (MRI),  functional magnetic resonance imaging (fMRI), and Transcranial Magnetic Stimulation (TMS).
Evolutionary Psychology01:20

Evolutionary Psychology

Evolutionary psychology explores the origins of human behavior and mental processes by framing them within the context of natural selection, a theory famously propounded by Charles Darwin. This field asserts that many behaviors common across human societies — ranging from instinctive fear reactions to complex social interactions — arose as evolutionary adaptations. These adaptations enhanced the survival and reproductive success of our ancestors, thereby becoming embedded in the human psyche...
Introduction to Cognitive Psychology01:20

Introduction to Cognitive Psychology

Cognitive psychology is the field of psychology dedicated to examining how people think. It attempts to explain how and why we think the way we do by studying the interactions among human thinking, emotion, creativity, language, and problem-solving, as well as other cognitive processes. Cognitive psychology studies how information is processed and manipulated in remembering, thinking, and knowing.
This field emerged in the mid-20th century, following a period dominated by behaviorism, which...
Lazarus's Cognitive Appraisal Theory01:20

Lazarus's Cognitive Appraisal Theory

Cognitive psychologist Richard Lazarus proposed the cognitive-mediational theory of emotions, which emphasizes how individuals' assessments of stressors significantly affect their experience of stress. According to Lazarus, the stress response is determined by a two-step appraisal process: primary appraisal and secondary appraisal. These cognitive appraisals help individuals evaluate the potential impact of a stressor and determine the adequacy of their coping resources.
Primary Appraisal:...
Cognition and Behavior01:23

Cognition and Behavior

Social psychology examines the complex interplay between individual mental processes and social interactions. Historically, the field was divided into two domains: social behavior and social cognition. Researchers focusing on social behavior analyzed actions within social contexts, such as conformity, aggression, or cooperation. Meanwhile, social cognition researchers investigated how people perceive, interpret, and mentally represent their social environments. However, modern perspectives no...
Automatic Processing and Automatic Social Behavior01:28

Automatic Processing and Automatic Social Behavior

Automatic processing refers to the cognitive operations that occur without conscious intent or awareness, playing a fundamental role in shaping social cognition and behavior. These processes enable individuals to navigate complex social environments efficiently by relying on mental shortcuts and pre-existing knowledge structures known as schemas. One of the most influential mechanisms underlying automatic processing is priming, which subtly activates mental representations through exposure to...

Area of Science:

  • Neuroscience
  • Cognitive Science
  • Computational Psychiatry

Background:

  • Understanding psychiatric disorders necessitates evaluating cognitive and motivational functions in preclinical settings.
  • Translational validity in research requires engaging tasks, efficient software for task switching, broad experimental setup compatibility, and extensible platform architectures.

Approach:

  • The Multi-task Universal Suite for Experiments (M-USE) is a software platform built using the Unity game engine and C#.
  • M-USE supports immersive tasks for humans and nonhuman primates, enabling within-session task switching.
  • It generates cross-platform builds (computers, tablets, websites) and is freely available with extensive documentation.

Key Points:

  • M-USE features a task library with seven pre-existing tasks assessing perception, attention, working memory, cognitive flexibility, self-control, memory, and problem-solving.
  • The platform was used to test nonhuman primates (NHPs) on up to six tasks per session.
  • Performance metrics align with the National Institutes of Mental Health's Research Domain Criteria (RDoC).

Conclusions:

  • M-USE offers a unique combination of features, including a cross-species task library, seamless task switching, and cross-platform capabilities.
  • Unlike existing systems, M-USE leverages video game technology for gamified tasks and is license-free.
  • This multi-task platform advances cross-species translational research into the neurobiology of cognitive and motivational functions.
