Question

Hen sasha eats a watermelon, many steps are involved for her brain to interpret what her taste receptors pick up. match the terms with their examples from this scenario.

Answer 1

- "In a blind testing, Sasha assumes the food is a watermelon based on its texture, water content and taste." This sentence is an example of bottom-up processing. This is a type of sensory processing and it refers to the process of building up from the smallest pieces to larger ones. In this case, Sasha tastes the food and from smaller pieces of information, she concludes to a more general idea that the food is a watermelon.

- "Cells in her taste buds send neural signals to the brain." This sentence is an example of transduction. Sensory transduction is the process of converting signals from the sensory cells to electric signals. The electric signals consist the neural signals that send the messages from the environment to the brain.

- "The food tastes like watermelon." This sentence is an example of perception. Perception refers to the organization and processing of sensory information. Perception involves the stimulation of the sensory system by stimuli from the environment which turns into signals in the nervous system. 

- "Sasha assumes the fruit served at the barbecue is watermelon since she has had watermelon in this context before." This sentence is an example of top-down processing. This is the second type of general processing involved in sensation. It refers to perception driven by cognition and its basis is that the brain uses its knowledge and expectation and predicts a conclusion.

- "Molecules from food stimulate receptors on her tongue." This sentence is an example of sensation. Taste sensation (or gustatory sensation) is one of the five senses. Taste is the process of the chemical reaction between the taste receptors and molecules of the substance consumed.
