tutorial week 5: experimentology + perception

1. Which one of the following is a human sense:

• • Electroception

• Echolocation

• Thermoception

• Magnetoception

• Equilibrioception

1. Principle of _____: “the whole is something else than the sum of its parts” 

According to Gestalt theory, which principle explains our tendency to perceive incomplete shapes as complete?

• Similarity

• Closure

• Continuity

• Figure-ground segregation

In signal detection theory, which of the following represents a "false alarm"?

• Stimulus is present, response is "yes."

• Stimulus is absent, response is "yes."

• Stimulus is present, response is "no."

• Stimulus is absent, response is "no."

What type of photoreceptor is responsible for high colour resolution and is concentrated in the foveal region?

• Rods

• Cones

• Ganglion cells

• Bipolar cells

Geons are fundamental shapes used in the recognition-by-components theory to identify objects.

• TRUE

• FALSE

Larger angular disparity in a mental rotation task leads to quicker and more accurate responses.

• TRUE

• FALSE

What role does the fovea play in visual perception?

• It is responsible for sharp central vision and contains a high density of cones.

• It processes peripheral vision with rods.

• It acts as the optic nerve's blind spot.

• It controls the dilation of the pupil.

Which of the following is a dependent variable in the mental rotation experiment?

• Angular disparity

• Same/different object pairing

• Accuracy

• Randomization method

What key concept does the mental rotation experiment rely on?

• Gestalt principles of grouping

• Signal detection thresholds

• Mental representation and rotation of 3D objects

• Visual perception in two-dimensional space
