Sensation Perception

Almost half the birds in the yard were brown cardinals and the rest were bright red cardinals, so Jimmy perceived them as two distinct groups of birds. This best illustrates the principle of:

• connectedness

• similarity

• closure

• relative clarity

Information processed below the normal level of awareness is called

• adaptive

• subliminal

• psychophysical

• subnormal

An auditory illusion whereby speech sounds are often mis-categorized when the auditory cues in the stimulus conflict with the visual cues from the speaker's face

• The McGurk Effect

• Shepard Tones

• song to speech phenomenon

• hearing paradox

Bryan perceived a duck instead of other animals when viewing an ambiguous image because he watched a documentary about ducks the previous night. Which of the following best explains why Bryan perceived a duck?

• Bottom-up processing, because he constructed the image of the duck piece by piece, starting with his

  sensory receptors.

• Bottom-up processing, because his perception of the duck was influenced by past experience.

• Top-down processing, because he constructed the image of the duck piece by piece, starting with his

  sensory receptors.

• Top-down processing, because his perception of the duck was influenced by past experience

• Color constancy, because his perception of the duck was not affected by different illuminations

As you talk with a friend at a party, her voice is distinct from all the other voices you hear. This illustrates the perceptual principle of:

• grouping

• cocktail party effect

• proximity

• closure

• conduction hearing loss

The tendency to organize stimuli into smooth, uninterrupted patterns is called    

• closure

• continuity

• similarity

• proximity

This is an example of the ....

• autokinetic effect

• phi phenomenon

• stroboscopic effect

• Ponzo illusion

• trichromatic theory

Which of the following best describes the concept of 'selective attention' in sensation and perception?

• A) The ability to focus on a specific stimulus while ignoring others

• B) The process of organizing and interpreting sensory information

• C) The tendency to perceive a complete image even when there are gaps

• D) The diminishing sensitivity to an unchanging stimulus

In the context of sensation and perception, what does the term 'sensory adaptation' refer to?

• A) The process of converting sensory input into neural signals

• B) The adjustment of sensory receptors to different levels of stimulation

• C) The ability to detect a stimulus 50% of the time

• D) The interpretation of sensory information by the brain

Which of the following is an example of 'perceptual set' in sensation and perception?

• A) Seeing a shape as a circle even when it is partially obscured

• B) Expecting to see a certain object in a picture and thus perceiving it

• C) Failing to notice a change in a visual stimulus

• D) The ability to detect a faint stimulus amid background noise
