sensation & perception psy1010

What are the four sensory systems?

We also have sensory systems that provide information about balance (the vestibular sense), body position and movement (proprioception and kinesthesia), pain (nociception), and temperature (thermoception).

Define sensation

When sensory information is detected by a sensory receptor.

afterimages

Using the different images that each eye receives in order to perceive depth is called using ________ cues.

binocular

subliminal messaging

can mildly influence behavior.

kinesthesia

What is the connection of sensation to the concepts of absolute threshold?

refers to the minimum amount of stimulus energy that must be present for the stimulus to be detected 50% of the time.
