Questions and Answers

Which of the following is NOT a reason why biopsychology is considered a science, despite often studying unobservable phenomena?

Biopsychologists rely on scientific inference to make deductions about unobservable processes.

Similar to studying gravity or electrons, biopsychologists can measure the effects of unobservable mechanisms.

Biopsychologists use rigorous testing to refine and discard less valid inferences based on observable effects.

Biopsychologists primarily use introspection to understand the processes underlying behavior. (correct)

Why does the world appear to move when you poke your eye with your finger, even though the world is stationary?

The movement of the eye is perceived as motion of the world because the brain does not distinguish between active and passive eye movements. (correct)

Poking the eye causes a sudden change in the focus of your vision, making the world appear to move.

The brain interprets the mechanical pressure on the eye as an indication of physical movement in the environment.

The retina is sensitive to pressure, and when you poke your eye, the retina sends a signal to the brain indicating movement.

What does the experiment using curare demonstrate regarding the perception of movement?

The brain's ability to compensate for eye movements during voluntary movement suggests that visual perception is actively constructed, not simply a passive reflection of retinal input. (correct)

Curare completely disrupts the visual system, causing hallucinations and the perception of movement even when there is none.

Curare provides evidence that the perception of movement is solely determined by the motion of objects across the retina.

Curare only affects the muscles responsible for voluntary movement, and therefore doesn't impact the perception of movement.

Why is it important to understand the relationship between active and passive eye movements in the context of biopsychology?

It demonstrates the complexity of the visual system and challenges simplistic explanations of how we perceive the world. (D) Signup and view all the answers
