Chapter.5 The Perceiving Mind (1)

The process of detecting environmental stimuli or stimuli arising from the body.

The process of interpreting sensory information.

The translation of incoming sensory information into neural signals.

The tendency to pay less attention to a nonchanging source of stimulation.

Perception based on building simple input into more complex perceptions.

A perceptual process in which memory and other cognitive processes are required for interpreting incoming sensory information.

Dogs apparently see blues, yellows, and grays.

The study of relationships between the physical qualities of stimuli and the subjective responses they produce.

The smallest amount of stimulus that can be detected.

The smallest detectable difference between two stimuli.

Signal detection - The analysis of sensory and decision-making processes in the detection of faint, uncertain stimuli.

What is an example of Absolute threshold?

What is an example of Difference threshold?

What is an example of Signal detection?

The sense that allows us to process reflected light.

The clear surface at the front of the eye that begins the process of directing light to the retina.

An opening formed by the iris.

The brightly colored circular muscle surrounding the pupil of the eye.

The clear structure behind the pupil that bends light towards the retina.

Layers of visual processing cells in the back of the eye.

Large-amplitude waves appear bright, and low-amplitude waves appear dim.

50% of our Cerebral cortex processes visual information.

Gamma rays, x-rays, ultraviolet rays, infrared rays, microwaves, and radio waves lie outside the capacities of the human eye.

Approximately 50% of our cerebral cortex processes visual information, in comparison to only 3% for hearing and 11% for touch and pain.

Light entering the eye travels through the cornea, pupil, and lens before reaching the retina. Among the landmarks on the retina are the fovea, which is specialized for seeing fine detail, and the optic disk, where blood vessels enter the eye and the optic nerves exits the eye.

An area of the retina that is specialized for highly detailed vision.

A photoreceptor specialized to detect dim light.

A photoreceptor in the retina that processes color and fine detail.
