Question 1

The terms sensation and perception refer to the same processes and are interchangeable.

Accepted Answer

Sensation and perception are different processes. Sensation refers to the physical process of receiving and encoding sensory information, while perception involves interpreting and making sense of that information. Sensation is the first step in the perceptual process, while perception involves higher-level cognitive processes such as attention, memory, and language.

Question 2

A sound coming from your left will reach your left ear faster and with more intensity than it will reach your right ear.Your brain can use these two facts to determine the location from which the sound is originating.

Accepted Answer

This is known as the "intensity and timing differences" cue, which our brain uses to locate the source of a sound. The difference in arrival time and intensity allows the brain to calculate the angle of the sound source relative to the center of the head.

Question 3

When measuring absolute threshold,reliable detection is said to occur when a person can detect a signal 99 percent of the time.

Accepted Answer

The absolute threshold is typically defined as the point at which a person can detect a signal 50 percent of the time.

Question 4

The intensity or brightness of light corresponds to the amplitude of the light wave.

Accepted Answer

The amplitude of the light wave determines the intensity or brightness of the light.

Question 5

Although humans have only about 1000 different types of receptors,we can detect about 10 000 different odours.

Accepted Answer

This is because the olfactory receptors in our nose can detect a range of different odor molecules and can distinguish between them based on their specific chemical structure and pattern of activation.

Question 6

Despite extensive research,no effective treatment for the symptoms of phantom limb pain have been found.

Accepted Answer

Various treatments, including medications, mirror box therapy, and nerve stimulation, have shown effectiveness in managing the symptoms of phantom limb pain for some individuals.

Question 7

The amplitude of a wave corresponds to a sound's pitch-the higher the amplitude,the higher the pitch.

Accepted Answer

The amplitude of a wave corresponds to a sound's volume or loudness, not its pitch. Pitch is determined by the frequency of the wave.

Question 8

Depth can be interpreted from a photograph using convergence as a cue.

Accepted Answer

The answer of Depth can be interpreted from a photograph...

Question 9

Dark adaptation is the process by which visual receptors become increasingly sensitive to dim light.

Accepted Answer

Dark adaptation is indeed the process by which visual receptors become increasingly sensitive to dim light.

Question 10

There are three basic types of cones in the retina,each of which responds maximally to a different wavelength.

Accepted Answer

This is true, and is the basis for color vision. The three types of cones are typically referred to as red, green, and blue cones, although their maximum sensitivity is to wavelengths that are closer to yellow-green, green, and blue-violet, respectively.
