Exam 5: Sensation and Perception

To account for the colour transduction process, the dual-process theory of colour combines elements of the trichromatic theory and the ______________ theory.

What is the physiological basis for dark adaptation? What are the two components of the dark adaptation curve?

How are the rods and cones distributed in the retina, and how do they contribute to brightness perception, colour vision, and visual acuity?

In the visual system, negative colour afterimages demonstrate the operation of

Describe the different types of colour blindness and how colour blindness is assessed. Explain how these different types of colour blindness are related to the various theories of colour perception. Define trichromats, dichromats, and monochromats.

Whether you are nearsighted or farsighted is largely dependent on the ability of your _______________ to focus the image directly onto the retina.

All of the following are environmental factors that affect attention EXCEPT

You are examining the sensory systems of a new species and notice a lot of free nerve endings. Most likely, you are looking at the

Imagine that you are brisk walking. Neural messages provided by your muscles, tendons, and joints give your brain feedback about the movements you are making in order to allow you to continue walking. This feedback is an example of your ___________________ sense.

When a nerve impulse is sent to the brain from the ear, that impulse originates from

Bottom-up processing is to top-down processing as

Let's say that you run a deprivation experiment in which kittens were raised from birth in an environment containing only horizontal stripes. Based on the research by Blakemore and Cooper (1970), how will this affect cells in their visual cortex?

As your eyes focus on an object that is close to you, muscles turn your eyes inward, producing feedback. This feedback produces the binocular depth cue called

Bottom-up processing occurs when individual stimulus units are taken by the nervous system and assembled into wholes. By contrast, when sensory stimuli are interpreted relative to pre-existing knowledge or expectations then __________ processing occurs.

In general, Gestalt theorists were proponents of _____________ processing principles.

Inattentional blindness refers to _______________.

A procedure results in pain relief without the use of naloxone, but the procedure is ineffective when naloxone is present, then we have direct evidence that ___________ may be responsible for the reduction in pain.

Cones are superior to rods for capturing fine detail because

The use of animated GIFs, or moving pictures, is common on the internet. Although they are perceived as conveying movement (like a video), they are actually just a series of still images cycled very quickly. This demonstrates the principle of _____.

The tendency of our visual system to perceive an object as having the same dimensions and measurements, even though the image of the object on our retina may change with distance is called ________________.
