Which psychologist would be most interested in how a person distinguishes between different tastes?

The psychologist most interested in how a person distinguishes between different tastes is the experimental psychologist. This field focuses on conducting experiments to investigate various aspects of human perception and cognition, including sensory perception.

Experimental psychologists design and carry out studies to explore how the sensory systems work, how people interact with their environment, and how they perceive qualities such as taste. Understanding how individuals differentiate between flavors requires careful experimental methods to measure responses to different stimuli and observe patterns in behavior.

In contrast, cognitive psychologists primarily explore mental processes such as memory, problem-solving, and decision-making; social psychologists study how individuals' thoughts and behaviors are influenced by the social context; developmental psychologists focus on how people change and develop over their lifespan. While each of these fields has valuable contributions to psychology, the specific investigation of taste discrimination aligns most closely with the experimental approach.
