Which order is correct?

• reception; transduction; transmission; interpretation

• reception; transmission; transduction; interpretation

• interpretation; transduction; transmission; reception

• transduction; transmission; reception; interpretation

Where in the brain is visual stimuli interpreted?

• Parietal lobe

• Temporal lobe

• Occipital lobe

• Frontal

What is the brain structure that sorts sensory information?

• Cerebral cortex

• Thalumus

• Hypothalamus

• Midbrain

What is the function of the cerebral cortex?

• To transduce sensory information

• To transmit sensory information

• To combine sensory information with existing information

• To interpret sensory information

The ability to recognise the difference between sensory stimuli is called ....

• Differential threshold

• Absolute threshold

• Reception

• Interpretation

The scientific measure of the absolute threshold is ...

• The maximum amount of energy required for a stimulus to be detected

• The smallest perceptible difference between stimuli that can be perceived roughly 50% of the time

• The lowest level of a stimulus that can be perceived roughly 50% of the time

• The sharpness of your sense and your ability to perceive it

Touch sensation is perceived in which brain region?

• Primary gustatory cortex

• Primary somatosensory cortex

• Parietal lobe

• Primary olfactory cortex

Transduction is...

• The process in which sensory information is interpreted by the appropriate brain region

• The process in which sensory information is detected by the appropriate receptive field

• The process in which sensory information is sorted by the midbrain

• The process in which raw sensory information is changed into a form that can be sent to the brain

A receptive field is...

• the area of space that provides sensory stimulation to the appropriate receptor

• the organ that collects sensory information

• the cell that collects and transducts sensory information

• the energy that is received by sensory receptors and perceived by the brain

Which of the following is NOT true?

• Perception cannot occur without transmission

• Sensation of stimuli occurs in a receptive field made up of receptor cells designed to detect specific types of information

• Interpretation of sensory information relies on memory

• Perception is only a biological process and not connected to psychological processes
