The organization and interpretation of olfactory information is one example of


Activation of the receptors by stimuli is called


Cells that are triggered by light, vibrations, sound, touch or chemical substances are called

The belief that our sensory systems are infallible and that our perceptions are perfect representations of the world around us is called

Naive realism

The perceptual process of filling in is guided by

preconceived notions and past experiences

The conversion of external energy into something that the nervous system can understand is know as


When u first put your hat on, u can feel it quite easily, but after a while you forget that you are wearing a hat at all- the sensation is gone. What happens

Sensory adaptation

The process by which unchanging information from the senses of taste, touch, smell and vision is ignored by the sensory receptor cells themselves is called....

Sensory adaptation

In the process aka ......., sensory receptors become less sensitive to repeated presentations of the same stimulus

Sensory adaptation

Sensory adaptation

Sounds that we hear are converted into electrical signals in neurons through a process called.....


The sensitivity of our sensory abilities and systems is demonstrated in our ....... thresholds.


Top down processing

What is absolute threshold?

Lowest level of stimulus needed for the nervous system to detect a change 50% of the time

Define sensory adaptation.

Activation is greatest when a stimulus is first detected.

Define Sense receptor

Specialized cell responsible for converting external stimuli into neural activity for a specific sensory system.

Define transduction

The process of converting an external energy or substance into electrical activity within neurons

Just noticeable difference

The smallest change in the intensity of a stimulus that we can detect.


The study of how we perceive sensory stimuli based on their physical characteristics.

Signal detection theory

The theory regarding how stimuli are detected under different conditions.

Synesthesia is......

A condition in which people experience cross-modal sensation

Parallel processing is......

the ability to attend to many sense modalities simultaneously.

The way our brain multitasks

Bottom up processing

Processing in which a whole stimulus is constructed from parts

e.g. perceiving an object on the basis of its edges.

Top down processing

Conceptually driven processing influenced by beliefs and expectancies.

............... is conceptually driven, whereas ........... is stimulus driven

Top-down ; bottom-up processing

Subliminal perception is.....

is perception below the limen or threshold of conscious awareness

In attentional blindness

Failure to detect stimuli that are in plain sight when our attention is focused elsewhere

The cocktail party effect

Explains how we can become aware of stimuli outside of our immediate attention when it's relevant to us.
