Question 1
Research on the perception of pitch has shown that
◦ frequency theory works best for frequencies above 5,000 Hz.
◦ place theory works best for frequencies below 1,000 Hz.
◦ between 1,000 and 5,000 Hz both place and frequency theories can operate.
◦ between 1,000 and 5,000 Hz, neither place nor frequency theory works.
Question 2
Research suggests that our moment-to-moment visual impressions of the world do not preserve precise details. One reason for this less-than-perfect representation may be that
◦ boundary extension contributes to memories.
◦ temporal integration is emplyed when it is not needed.
◦ spatial integration is used when temporal integration is needed.
◦ the visual system is not sufficiently developed to register details.
