Ganel Et Al

question 29

Multiple Choice

Ganel et al. (2008) designed a visual illusion (modified Ponzo illusion) in which one line appears to be longer than another, when, in reality, the opposite is true. Participants are asked to judge the line lengths and to reach and grab the ends of the lines. The results of this investigation reveal

• A) the interaction of the ventral and dorsal stream.
• B) that the visual illusion affects both the ventral and dorsal streams.
• C) the effects of damage to the ventral pathway.
• D) that the illusion only affects ventral stream processing.

Definitions:

Ammeter Shunt

A device used to change the full scale value of an ammeter by providing another path for current flow. Most ammeter shunts produce a voltage drop of 50 millivolts when rated current flows through them.

Low-resistance

A characteristic of a material or component that allows a large amount of electrical current to pass through with minimal opposition.

Spike

A sudden, sharp increase or peak in the magnitude of a variable, often used in the context of electrical voltage or signals.

Low Values

Refers to measurements or quantities that are significantly below average or expected levels.
