Time course research involves studying how biological or behavioral processes change over time. This type of research typically involves collecting data at multiple time points to track the progression or change of a particular variable. Time course studies can help researchers understand how different factors influence the development or trajectory of a process, and can provide insight into the underlying mechanisms driving these changes. Time course research is commonly used in fields such as psychology, biology, medicine, and neuroscience to examine topics such as growth, learning, development, and disease progression.
