The tiny bones in the middle ear serve to transfer incoming sound waves from the cochlea to the basilar membrane.

The decreasing sensitivity of sensory receptors to a constant stimulus is called sensory adaptation.

With ageing, the eyeball typically becomes longer over time, contributing to the development of hyperopia.

Sound localization is made possible by how the nervous system processes the time and intensity differences of sounds arriving at the two ears.

The frequency of a sound corresponds to our perception of the loudness of the sound.

Under conditions of low illumination, cones are most sensitive to light in the green-yellow part of the colour spectrum.

There are significantly more rods than cones located in the fovea.

When various pieces of visual information related to a stimulus object are processed simultaneously it is referred to as parallel processing.

Perception has been likened to the process of creating a theory, and perceptual sets are the representations or images that we make use of to test our perceptual theories.

Research on the impact of subliminal stimuli has shown that they have a stronger effect on behaviour than they do on attitudes.

The fact that a door appears to have the same shape whether we look at it from the side or front-on is an example of what is called a perceptual constancy.

The Young-Helmholtz trichromatic theory of colour vision is based on the laws of additive colour mixture and argues that each of the three types of cones is most sensitive to one wavelength of light.

Sensation is to stimulus detection as perception is to sense-making.

The opponent-process theory of colour combines the dual-process and trichromatic theories of colour.

The four tactile sensations that people are sensitive to are pressure, warmth, pain, and cold.

The Gestalt law of proximity states that elements that are near one another are likely to be perceived as part of the same configuration.

Research has suggested that endorphins play a significant role in the phenomenon of menstrual synchrony.

The two complementary processes involved in attention are focusing on certain stimuli and filtering out other information.

The scientific area of psychophysics is concerned with the determination of absolute thresholds and difference thresholds.

The smallest difference between two stimuli that people can perceive 50% of the time is called the absolute threshold.
