In signal detection tasks, naysayers will have more hits than yea-sayers.

Like human infants, kittens are born with the ability to detect horizontal lines and vertical lines. In one famous study, kittens were reared in darkness for five months after birth. But for several hours each day, they were put into a special cylinder that permitted them to see only vertical or horizontal lines and nothing else. Describe the results of this research study.

Which of the following physical characteristics of the sound wave corresponds to the psychological dimension of timbre?

The ________________ contain receptors responsible for a sense of bodily movement.

When newborn kittens were exposed to either vertical or horizontal stripes-and nothing else-for several months, it was found that:

Pain is an indispensable part of our evolutionary heritage, for it alerts us to illness and injury.

Despite the impressive sensory skills possessed by humans, the human senses are tuned into only a narrow band of physical energies. Discuss several species that are able to pick up signals that humans do not pick up. What can each of these species detect that humans cannot?

The reduction of sensory responsiveness that occurs when stimulation is unchanging is called sensory deprivation.

DJ is asked to participate in the replication of a famous experiment. The researchers place virtual-reality goggles on him so he sees the world from a camera placed on top of a mannequin. The researchers then stroke the mannequin's arm while simultaneously doing the same thing to DJ's arm. If the results of the experiment are consistent with the original study, DJ is likely to:

During a lecture, a classmate draws your attention to a buzzing fluorescent light that you had not previously noticed. What will happen to your perception of figure and ground?

The visual receptors are located in the _______________, which is located in the back of the eye.
