Question 1: Cell body

Answer:

Largest part of a typical neuron; contains the nucleus and much of the cytoplasm. Other parts of the neuron attaches to it

Question 2: Neural processing

Answer:

Operations that transform electrical signals within a network of neurons or that transform the response of individual neurons.

• transmit signals from the receptors, though the retina, to the brain, and then within the brain

• process these signals as

Question 3: frontal lobe

Answer:

Receiving signals from all of the senses, the frontal lobe plays an important role in perceptions that involve the coordination of information received through two or more senses

Question 4: The seven steps of the perceptual process in order

Answer:

distal stimulus, proximal stimulus, receptor processes, neural processing, perception, recognition, action

Question 5: How are thresholds measured?

Answer:

Magnitude Estimation

Question 6: Cognitive Influences on Perception

Answer:

knowledge, memories, and expectations (the starting place for top-down processing)

Question 7: Perception

Answer:

complex processes that involve the higher-order mechanisms such as interpretation and memory that involve activity in the brain

Question 8: Action

Answer:

Motor activities in response to a stimulus

Question 9: Phenomenological Report

Answer:

Describing what you perceive in your enviroment

Question 10: Dendrites

Answer:

Branchlike parts of a neuron that are specialized to receive information

Question 11: Diffusion Tensor Imaging (DTI)

Answer:

Allows us to see how areas of the brain are connected to each other. We are able to see the actual highways instead of just the landmarks. It is very detailed about where it happens, but is not very detailed about when it occurs

Question 12: Lens

Answer:

located behind the cornea; helps to focus light on the retina

Question 13: Absolute Threshold

Answer:

The smallest stimulus level that can just be detected 50% or above of the time

Question 14: Top-down processing

Answer:

Processing based on the perceiver's previous knowledge or cognition factors. Also known as knowledge-based processing Question 15: One way to study stimulus-behavior relationship:

Answer:

Psychophysics

Question 16: Reaction Time

Answer:

the time between the presentation of a stimulus and the person's reaction to it

Question 17: Depolarization

Answer:

The change from a negative resting potential to a positive action potential (caused by opening of sodium channels)

Question 18: Action Potential

Answer:

The electric signal travelling through the axon.A neural impulse; a brief electrical charge that travels down an axon

Question 19: Magnitude Estimation

Answer:

a psychophysical method in which participants assign values according to percieved magnitudes of stimuli (i.e. the light is twice as bright as the first one)

Question 20: Transactional Magnetic Stimulation

Answer:

It is a direct, non-permanent manipulation, but its purpose is that the magnetic stimulus stimulates or disrupts functioning

Question 21: Three Relationships of Perception

Answer:

Relationship A: stimulus-perception relationship

Relationship B: stimulus-physiological relationship

Relationship C: physiology-perception relationship

Question 22: Classical Psychophysical Methods

Answer:

a combination of Method of Adjustment and the Method of Constant; opened the way for the founding of scientific psychology by providing methods to measure an aspect of the mind

Question 23: The Stimulus-Perception Relationship (A)

Answer:

relates stimuli to behavioral responses; the main relationship studies during the first 100 years of the scientific study of perception

Question 24: Perceptual Process

Answer:

A sequence of steps leading from the enviroment to perception of a stimulus, recognition of the stimulus, and action with regard to the stimulus

Question 25: Receptor processing

Answer:

when the visual receptors that line the back of the eye receive the light reflected from the tree, they do

two things:

• they transform enviromental energy into electrical energy

• they shape perception by the way they respond to different properties
