Chapter 3: Sensation and Perception (psychology)

The process by which we select, organize, and interpret sensory information in order to recognize meaningful objects and events is called

• parallel processing.
• perception.
• accommodation.
• sensation.

The detection and encoding of stimulus energies by the nervous system is called

• signal detection.
• synaesthesia
• sensation
• accommodation.

Because she was listening to the news on the radio, Mrs. Schultz didn't perceive a word her husband was saying. Her experience best illustrates

• gate-control theory.
• choice blindness.
  
• selective attention.
  
• opponent-process theory.

In one experiment, most of the participants who viewed a videotape of men tossing a basketball remained unaware of an umbrella-toting woman sauntering across the screen. This illustrated

Weber's law is relevant to an understanding of

• absolute thresholds.
• difference thresholds.
• sensory interaction.
• parallel processing.

Kinesthesis refers to the

• process of organizing and interpreting sensory information.
• diminished sensitivity to an unchanging stimulus.
• system for sensing the position and movement of individual body parts.
• quivering eye movements that enable the retina to detect continuous stimulation.

If we are testing your sound absolute threshold what percentage of the time must you hear the minimum stimulus in order for the absolute threshold to have been found?

• 20%

• 35%

• 50%

• 60%

A researcher presents two lights of varying brightness to a subject who is asked to respond "same" or "different" by comparing their intensities. The researcher is seeking the

• just noticeable difference.

• absolute threshold.

• subliminal threshold.

• minimal threshold.
