D Serial and conjunction

Review Detailed Answer

Correct Answer: Serial and conjunction

Sometimes the visual information available to us about a stimulus is ambiguous because of differences in depth, lighting or shading cues. For example, patterns of shading can create the illusion of objects as protruding from a visual field. How do we make sense of the visual information to recognize ambiguous stimuli?

A Visual system relies on other people’s Knowledge of objects to identify ambiguous stimuli

B Visual information about protruding objects is impossible to process

C Visual system relies on assumptions about the physical world to identify ambiguous stimuli

D Both (a) and (c)

Review Detailed Answer

Correct Answer: Visual system relies on assumptions about the physical world to identify ambiguous stimuli

How are cortical cells arranged to best transmit neural information?

A Cells are vertically organized in columns

B Cells are horizontally organized in straight lines

C Cells are organized around the optic nerve

D Cells are vertically organized by volume

Review Detailed Answer

Correct Answer: Cells are vertically organized in columns

Feature integration theory attempts to explain which aspect of object perception?

A How we perceive individual features of objects when brain is impaired

B How we perceive multiple colours to perceive a whole colour

C How we integrate touch and vision

D How we integrate individual features of objects to perceive a whole object

Review Detailed Answer

Correct Answer: How we integrate individual features of objects to perceive a whole object

Which of the following statements is NOT true?

A The rods and cones in the retina function in bright and dim light respectively

B The cones are of three types, which are selective to different ranges of light wavelength

C The information from the cones is re-organized in the retina to give-green, red and blue-yellow opponent channels

D There is also group of large retinal cells alongside the smaller color-opponent cells that respond to the difference between the luminances in their center and surrounding regions

Review Detailed Answer

Correct Answer: The rods and cones in the retina function in bright and dim light respectively

In conjunction search:

A The target/distractor difference is not based on a single feature, but on conjunctions of features

B Search time for the target is not constant, but instead rises with the number of distractors

C The observer apparently searches through the display serially, scanning each term or small group of items) successively (serial search)

D All of the above

Review Detailed Answer

Correct Answer: All of the above
