Basic concepts of sensation and perception

Difference

Ahmad asked Reza to turn up the radio, so Reza increased the volume from level 5 to level 7. Reza could hear the difference but Ahmad couldn't. They differed in their _____ threshold.

top-down

Racial and ethnic stereotypes can sometimes bias perceptions of others' behaviors. This best illustrates the impact of _____ processing.

diminished sensitivity as a result of repeated stimulation.

Sensory adaptation is defined as:

what is the motor/ cerebral cortex

is in charge of your bodies coordination and planning of motor movements. Examples of this part of our brain in action are walking, talking and chewing

frontal lobe

is responsible for decisions such as should I eat or drink.

Parietal lobe

is responsible for information being processed. Information that your body must process all the time is: what temperature it is or how hot or cold something is you may be consuming

occipital lobe

is responsible for the sents brought in by your nose. This is different from the others as it doesn't use the thalamus.

Temporal Lobe

is in charge of processing sound like speech or music being collected by your ears

context

A neutral facial expression may be perceived as sadder at a funeral than at a circus. This best illustrates a _____ effect.

sensory adaptation.

Barbara stubbed her toe last night. Today, she is painfully aware of her toe. Barbara does NOT usually notice her toe due to:

adaptation

Carole stubbed her toe last night. Today, she is painfully aware of her toe. Carole does NOT usually notice her toe due to sensory _____.

taste

More specifically I used the Gustatory cortex in my brain to complete the very necessary action of eating.

perceptual set.

People perceive an adult-child pair as looking more alike when told they are parent and child than when they are told that the adult and child are unrelated. This BEST illustrates the impact of:

Weber's

The difference threshold is greater for heavier objects than for lighter ones. This best illustrates _____ law.

ears

This also used the thalamus but contains a different processing center in the brain from where vision comes from

smell

When I am using my nose I am also using the olfactory bulb instead of the thalamus.

Sensation

_____ refers to the process by which our sensory receptors and nervous system receive and represent stimulus energies from our environment.

lobe

a certain area that makes up a cortex

What is the somatosensory cortex?

is a web of sensory neurons which sense the outside and inside of you body.

Where is the somatosensory cortex located?

is between the parietal lobe and the motor cortex.

feel

somatosensory cortex or parietal lobe in order to get to the light which then lead me to starting the coffee pot.

Transduction

the action or process of converting something and especially energy or a message into another form.

eyes

the thalamus and the occipital lobe in order for those visual messages to be passed from my brain to their necessary functions in my body
