What is a characteristic of a developmental psychologist's study on toddler interactions with caregivers?

A developmental psychologist studying toddler interactions with caregivers often uses video recordings to capture real-time behaviors and interactions. This method allows the researcher to analyze the subtleties of these interactions, such as non-verbal cues, emotional responses, and patterns of communication. By assessing the effectiveness of interventions based on observed behaviors, the researcher can gain insights into developmental milestones and the influence of caregivers on toddlers' social and emotional growth.

Utilizing video recordings provides a rich source of data that can be revisited and analyzed multiple times, offering a more comprehensive view of the interactions that may not be fully appreciated through direct observation alone. This approach is particularly important in developmental psychology, where understanding the nuances of behavior is key to identifying effective intervention strategies.
