but it is...

Perception

Definition: the ability to become aware of your surroundings

You use your sensory organs (zintuigen) for this.

There are five basic sensory organs

- ears

- eyes

- tongue

- nose

- skin

These organs sense (waarnemen) several things

Sense of hearing (gehoor)

Sense of taste (smaak)

Sense of balance (evenwicht)

Sense of smell (reuk)

Sense of temperature 

Sense of presure

Connect the sensory organs to the senses

Sense of pressure

Sense of sight

Sense of hearing

Sense of balance

Sense of smell

Sense of taste

Sense of temperature

How do these organs sense?

How do these organs sense?

Organs are made of cells

How do these organs sense?

Organs are made of cells

Several cells have different functions

Receptors

What do they sense?

Stimulus = information obout the environment

One stimulus, two stimuli

(Nederlands = prikkel)

Sense

Stimuli

Music

Taste

Sweet candy

Sight

Light

Hearing

Smell

Itchy sweater

An itchy sweater is a stimulus

1. Your receptors are activated by the sweater

2. The receptors send an impuls to your brain

3. You realise you are wearing an itchy sweater

You feel the itchy sweater, but don't feel normal clothes

Why is that?

Stimuli vs Impulses

Connect the terms with their definition

Write down next to fig 1:     A sense = a type of stimuli that is                                                                  percieved by a certain sensory organ

In the text under fig 1:          A sense is an organ ...

                           should be        A sensory organ is an organ ...

Adjust table 1 (page 89)

First collumn: not 'Sensory organ' but Sense / type of receptor

Because: A sense of something cannot be an organ

Second collumn: not 'Location' but Sensory organ

Because: These are not only locations, but the exact organs
