GRE® Psychology Biological: Sensation and Perception Part 7
This deck covers key concepts in sensation and perception, focusing on the roles of different nerve fibers, proprioceptors, the vestibular system, and psychological theories such as Structuralism and Gestalt psychology.
What are the primary roles of A-β, A-δ, and C fibers in the nervous system?
A-β fibers: Convey touch and pressure sensations A-δ fibers: Transmit fast pain and temperature sensations C fibers: Carry slow pain and temperature sensations A-β fibers are myelinated and have a larger diameter, allowing them to conduct signals rapidly. A-δ fibers are thinly myelinated and are involved in transmitting sharp, acute pain. C fibers are unmyelinated, resulting in slower signal transmission and are associated with dull, aching pain.

True or False: Muscle spindles and Golgi tendon organs are both types of proprioceptors.
True Proprioceptors provide information about body position and movement. Muscle spindles detect changes in muscle length, while Golgi tendon organs m...

What are the primary roles of A-β, A-δ, and C fibers in the nervous system? | A-β fibers: Convey touch and pressure sensations A-δ fibers: Transmit fast pain and temperature sensations C fibers: Carry slow pain and temperature sensations A-β fibers are myelinated and have a larger diameter, allowing them to conduct signals rapidly.

True or False: Muscle spindles and Golgi tendon organs are both types of proprioceptors. | True Proprioceptors provide information about body position and movement. Muscle spindles detect changes in muscle length, while Golgi tendon organs monitor tension in the muscles. |
What is the primary function of the semicircular canals? | Detect rotational movement of the head. The semicircular canals are three fluid-filled tubes in the inner ear that help maintain balance by detecting head rotations. Each canal corresponds to a different plane of motion. |
True or False: The utricle is mainly responsible for detecting gravitational forces. | False The utricle and saccule are part of the vestibular system in the inner ear. The utricle detects changes in horizontal movement and head position relative to gravity, while the saccule primarily senses vertical movements. |
What is the primary focus of Structuralism in psychology? | It focuses on breaking down mental processes into their most basic components. Structuralism, championed by Wilhelm Wundt and Edward Titchener, aims to identify the basic elements of consciousness through introspection. It was one of the first major schools of thought in psychology. |
How does Gestalt psychology differ from Structuralism? | Gestalt psychology emphasizes that the mind perceives things as whole forms rather than the sum of their parts. Gestalt psychology, founded by Max Wertheimer, opposes Structuralism by arguing that psychological phenomena cannot be understood by simply analyzing their components. Instead, it focuses on how people integrate and organize information into meaningful wholes. |
True or False: Empiricism emphasizes the role of innate ideas in knowledge acquisition. | False Empiricism, associated with philosophers like John Locke, asserts that knowledge comes primarily from sensory experiences and evidence-based observation, rejecting the notion of innate ideas. |
What is pareidolia, and how is it an example of a top-down error? | It is the tendency to perceive a familiar pattern, such as a face, where none actually exists. Pareidolia is an example of a top-down processing error where expectations and previous knowledge influence perception, leading to the interpretation of random stimuli as significant objects. |
