- "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.

Answer from: Quest

the earth’s crust is broken into separate pieces called tectonic plates (fig. 7.14). recall that the crust is the solid, rocky, outer shell of the planet. it is composed of two distinctly different types of material: the less-dense continental crust and the more-dense oceanic crust. both types of crust rest atop solid, upper mantle material. the upper mantle, in turn, floats on a denser layer of lower mantle that is much like thick molten tar.

each tectonic plate is free-floating and can move independently. earthquakes and volcanoes are the direct result of the movement of tectonic plates at fault lines. the term fault is used to describe the boundary between tectonic plates. most of the earthquakes and volcanoes around the pacific ocean basin—a pattern known as the “ring of fire”—are due to the movement of tectonic plates in this region. other observable results of short-term plate movement include the gradual widening of the great rift lakes in eastern africa and the rising of the himalayan mountain range. the motion of plates can be described in four general patterns:

collision: when two continental plates are shoved together

subduction: when one plate plunges beneath another (fig. 7.15)

spreading: when two plates are pushed apart (fig. 7.15)

transform faulting: when two plates slide past each other (fig. 7.15)
