2 when we tickle ourselves?
Why don’t we laugh when we tickle ourselves?

3 Some believe that laughing caused by tickling is a built-in reflex-- even babies do it. In order for tickling to work, the brain needs tension & surprise. When you tickle yourself, there is no tension or surprise. There is some evidence that the cerebellum may be involved in this phenomenon. In effect, the cerebellum informs the area called the somatosensory cortex what sensation to expect (“it's just you….don't get excited”), which diminishes the tickling sensation.

4 THE HUMAN BRAIN

5 Cerebrum thinking humor memory learning reading and language
voluntary muscle movement interpreting the senses

6 Humor is hard to define, but we know it when we see it.
One theory suggests that humor consists of surprise - we don't end up where we thought we were going reinterpretation of what happened to make it fit the new perspective Processing Time Humor is interpreted by the right frontal lobe of the brain People with damage to their right frontal lobe don't “get” jokes. Typically, this is because they have trouble with the reinterpretation stage of the process. For instance, given a joke with a choice of punch lines, they can't tell which one is funny.

7 Humor plays a powerful role in human life, and it has wide-ranging effects.
Humor can: emotionally unite people help us cope with daily stresses fight depression boost the capabilities of the immune system

9 MOMENTARY MEMORY ACTIVITY
Jot down 20 random single digits (from 0 - 9) Find a partner. Partner A divulges a single digit at a time. Partner B recalls all the numbers, starting from the beginning, adding the new digit last. Example: Partner A: “One” Partner B: “One” Partner A: “Eight” Partner B: “One, eight” Continue until Partner B messes up. Record the number of digits he/she WAS able to remember without messing up. Switch roles. Collect class data.

11 TRANSFERRING INFORMATION FROM MOMENTARY TO SHORT-TERM MEMORY

12 Study the following for one minute:

13 You have 30 sec. to write down as many objects you can remember!

14 What were some of your “tricks”?
All those “tricks” you described are common methods for committing information to memory (learning)

15 the period which elapses between start & finish
Process Time the period which elapses between start & finish - recognition - memory retrieval - output Stroop Effect

16 Cerebellum controls balance works with the cerebrum to produce smooth,
controlled, muscle movements

17 try to “outsmart” your foot
1. While sitting at your desk in front of your computer, lift your right foot off the floor and make clockwise circles with it. 2. Now, while doing this, draw the number '6' in the air with your right hand….. Your foot will change direction. You can’t do it. It's pre-programmed in your brain!

18 Pituitary Gland makes and stores hormones : oxytocin prolactin
FSH and LH growth hormone endorphins

19 Hypothalamus recognizes anger recognizes thirst recognizes hunger
recognizes fatigue regulates body temperature

20 Pineal Gland makes and secretes melatonin, which regulates bodily rhythms, including: biological clock (sleep/wake cycle) seasonal changes

21 Pons maintains consciousness and sleep controls breathing

22 Medulla Oblongata controls breathing & heartbeat
relays messages to spinal cord controls reflexes: sneezing coughing swallowing sucking (in babies) vomiting
