Dissociation theory
________ seeks to explain why, when no one is watching, previously hypnotized people may carry out posthypnotic suggestions (which are made during hypnosis but carried out after the person is no longer hypnotized)
Rods
________**: retinal receptors that detect black, white, and gray, and are sensitive to movement; necessary for peripheral and twilight vision, when cones dont respond.
William Molyneux

Optic nerve
________ is an information highway from the eye to the brain.
David Hubel
________ and Torsten Wiesel showed that our visual processing deconstructs visual images and then reassembles them.

________ (German philsophist and scientist) studied the edge of our awareness of these faint stimul.
volley principle
Enter the ________: Like soldiers who alternate firing so that some can shoot while others reload, neural cells can alternate firing.
Visual Cliff
________**: a laboratory device for testing depth perception in infants and.
Perception
________ is not just opening a shutter and letting a picture print itself on the brain.
central nervous systems
Dampening the ________ attention and responses to painful experiences- mimicking painkilling drugs.
Hue
________**: the dimension of color that is determined by the wavelength of light; what we know as the color names blue, green, and so forth.
Daryl Bem
________ has made his research materials available to anyone who wishes to replicate his studies.
Depth Perception
________**: the ability to see objects in three dimensions although the images that strike the retina are two- dimensional; allows us to judge distance.
Accommodation
________**: the process by which the eyes lens changes shape to focus near or far objects on the retina.
visual field
Figure- ground the organization of the ________ into objects (the figures) that stand out from their surroundings (the ground)
Cones
________ detect fine detail and give rise to color sensations.
Clairvoyance
________: perceiving remote events, such as a house on fire in another state.
brain circuits
The ________ processing our physical sensations sometimes interact with ________ responsible for cognition.
Parapsychology
________:** the study of paranormal phenomena, including ESP and psychokinesis.
Large fiber activity
________ (stimulated by massage, electric stimulation, or acupuncture) can close the gate, blocking pain signals.
register information
Claimed: Our brain does more than ________ about the world.
Signal detection theorists
________ seek to understand why people respond differently to the same stimuli.
Intensity
________ is determined by the waves amplitude (height)
Hypnosis
________**: a social interaction in which one person (the hypnotist) suggests to another (the subject) that certain perceptions, feelings, thoughts, or behaviors ANSWER: will spontaneously occur.
Transduction
________**: conversion of one form of energy into another.
Perceptual Adaptation
________**: the ability to adjust to changed sensory input, including an artificially displaced or even inverted visual field.
analysis
Bottom- Up Processing:** ________ that begins with the sensory receptors and works up to the brains integration of sensory information.
Smell
________ is a big part of taste.
Absolute Threshold
________**: the minimum stimulus energy needed to detect a particular stimulus 50 percent of the time.
Axons
________ twine together like the strands of a rope to form the optic nerve.
Retina
________**: the light- sensitive inner surface of the eye, containing the receptor rods and cones plus layers of neurons that begin the processing of visual information.
pieces of information
Gestalt psychologists emphasized our tendency to integrate ________ into meaningful wholes.
Gibson
________ and Richard Walk designed a series of experiments in their Cornell University laboratory using a visual cliff.
rapid series
Perceives a(n) ________ of slightly varying images as continuous movement.
Melzack
________ and Wall theorized that when tissue is injured, the small fibers activate and open the gate.
Phi Phenomenon
________**: an illusion of movement created when two or more adjacent lights blink on and off in quick succession.
Sensory Adaptation
________:** diminished sensitivity as a consequence of constant stimulation.
Ronald Melzack
Psychologist ________ and biologist Patrick Wall proposed the gate- conttrol theory.
Damage
________ to the cochleas hair cell receptors or the auditory nerve can cause sensorineural hearing loss (or nerve deafness)
Middle Ear
________**: the chamber between the eardrum and cochlea containing three tiny bones (hammer, anvil, and stirrup) that concentrate the vibrations of the eardrum on the cochleas oval window.
Perceptual Constancy
________**: perceiving objects as unchanging (having consistent color, brightness, shape, and size) even as illumination and retinal images change.
sensory receptors
Sensation**: the process by which our ________ and nervous system receive and represent stimulus energies from our environment.
Feature Detectors
________**: nerve cells in the brain that respond to specific features of the stimulus, such as shape, angle, or movement.

relative luminance
Depends on ________- the amount of light an object reflects relative to its surroundings.
