Tactile Discrimination: Exploring Receptive Fields
Grade Level: Middle School; Type: Life Science Human Perception, Tactile Discrimination
- Learn about tactile discrimination.
- Learn about receptive fields, and how and why their sizes vary.
- Think about the adaptive utility of an important aspect of our physiology.
- What kind of tactile receptors are being activated in this two-point discrimination task?
- Why would our species have evolved to have smaller receptive fields on some parts of the body than others?
What's more ticklish: your feet or your elbows? Different areas of our bodies are more sensitive than others. In this experiment, we'll discover how and why certain parts of our bodies are more sensitive than others, and we'll learn about the receptive field, the part of a sensory neuron that feels for us.
