Unit 6 Continued

Implicit Learning -
Observable improvements in a person's motor performance of which the person has no awareness.
Observational Learning:
•Albert Bandura and his BoBo Doll
•We learn through modeling behavior from others.
•Observational learning + Operant Conditioning
Latent Learning: sometimes learning is hidden.
Insight Learning: Wolfgang Kohler and his chimpanzees.
Some animals learn through the "ah ha" experience.
Pos. Punishment- something bad added to decrease unwanted behavior
Neg. Punishment- something good removed to cause unwanted behavior to decrease.

State of Consciousness(sleep, hypnosis, drugs)
Sleep- a state of consciousness
(We are less aware of our surroundings)
Levels:
Conscious
Subconscious
Unconscious
Daydreaming:
•help us prepare for future events
•nourish our social development
• can substitute for impulsive behavior
Fantasy Prone Personalities:
Someone who imagines and recalls experiences with lifelike vividness and who spends considerable time fantasizing.
Biological Rhythms:
Annual cycles- seasonal variations (ex. Hibernation. Seasonal affective disorder)
28 day cycle- menstrual cycle
24 hr cycle- our circadian rhythm
90minute cycle- sleep cycles.
Circadian Rhythm:
•our 24hr clock
•body temp and awareness changes throughout the day
(Best to test or study during circadian peaks.)
Sleep stages: (5)
•takes about 90-100min  for all stages to pass., brain waves will change according to sleep stage, first 4 stages are called NREM sleep, 5thbstage is REM sleep.
1) half wake, half sleep
Only last a few minutes
Eyes roll slightly
Brain produces Theta Waves (high amplitude, low frequency/ slow)
2) baseline of sleep
90minute cycle , occupies about 45-60%  of sleep
More Theta Waves get progressively slower
3) slow wave sleep, produce delta waves, if woken will be groggy (vital for restoring body's growth, hormones and good health)
3&4) may last 15-30min, slow wave because brain activity slows dramatically from theta rhythm of stage 2 to the much slower delta and the height or amplitude of the waves increases dramatically.
Delta sleep (deepest stage of sleep NOT REM and most restorative)
That of a sleep deprived persons.
In children, delta sleep can occupy up to 40% of all sleep time, "dead sleep"
5) REM SLEEP 20-25% of nights
Breathing, heart rate and brain wave activity quicken.
Vivid dream
Lucid dream
rapid eye movement, very active brain , where dreams usually occur.  Body essentially paralyzed.

5/14/14
Insomnia- problems falling asleep, affects 10% of the population.
Narcolepsy- suffer from sleeplessness and may fall asleep at unpredictable or inappropriate times.  Directly into REM sleep. Less than .001% of population.
Sleep Apnea- a person stops breathing during their sleep. Wake up momentarily, gasps for air, then falls back asleep. Very common, especially in heavy males. CAN BE FATAL
Night Terrors- sleep disorder characterized by high arousal and an appearance of being terrified. Occur in Stage 4, not REM and are not often remembered.
Sleepwalking (Somnambulism)- affecting an estimated 10% of all humans at least once in their lives.
•most often occurs during deep non-REM sleep (stage 3 or stage 4 sleep) early in the night.

Unit 6

Memory: the persistence of learning over time through the storage and retrieval of information.
Memory process-
•encoding- the processing of information into the memory system.
•storage-the retention of encoded material over time.
•retrieval- the process of getting the information out of memory storage.
Recall VS. Recognition:
•With recall- you must retrieve the information from your memory
•with recognition- you must identify the target from possible targets.
Flashbulb Memory: a clear moment of an emotionally significant moment or
event.

Unit V Fun Facts

This unit was definitely a lot! Thank goodness i do not have to retype all those notes. Here are a few fun facts of what we covered in class!

Sensation and Perception

Sensation is your window to the world and Perception is interpretation of what comes in your window.
                                                  I. Sensation
                                                             
                                                                      Le eye
Fun Fact: Light passes through the eyes in the following order: Cornea -> Pupil -> Lens -> Retina

Cognitive Development

Cognitive Development by Jean Piaget
*Kids learn differently than adults.
--> Schemas: Understanding of the world around us
                    * Children view the world through schemas
--> Assimilation: Incorporating new experiences to existing schemas
--> Accommodation: Changing an existing schema to adopt to new information

Stages of Cognitive Development
1. Sensorimotor Stage (0-2 years)
  - Experience the world through our senses
  - Do not have object permanence.

Social Development

Stranger Anxiety: Where an infant encounters a stranger and they exhibit anxiety.
Separation Anxiety: Whenever a child is separated from their parent.

Attachment: Harry Harlow and his monkey
                   Harry showed that monkeys needed touch to form attachment
                  * Wire monkey V. Cloth monkey

Critical Periods: The optimal period shortly after birth when an organisms exposure to certain stimuli or experiences produce proper development.

Types of Attachment 
1. Secure
2. Avoidant
3. Anxious /ambivalent

Developmental Psychology

                                           Developmental Psychology: From birth to death
Nature                                                 Vs.                                       Nurture
The way you were born                                                          The way you were raised.

Prenatal Development: Conception begins with the drop of an egg and the release of about 200 million sperm.

  • The sperm seeks out the egg and attempts to penetrate the eggs surface.
Once the sperm penetrates the egg- we have a fertilized egg called...the Zygote
  • 1st stage of prenatal development lasts about 2 weeks and consists of rapid cell division.
                                                       Zygotes
  • Less than half of all zygotes survive first two weeks.
  • About 10 days after conception, the zygotes will attach itself to the uterine wall
  • The outer part of the zygote becomes the placenta (Which filters nutrients).

Meet the Lobes

-Cerebral cortex is made up of four lobes.
I. Frontal Lobe

  • Abstract thought and emotion control
  • Contains motor cortex: Sends signals to our body., controlling muscle movement.
  • Contains Broca's Area: Responsible for controlling muscles that produce speech.
  • Damage to the Broca's Area is called Broca's Aphasia: Unable to make movements to talk.
  • Motor Cortex: Left hemisphere controls the right side of the body. 
II. Parietal Lobe
  • Contains sensory cortex receives incoming touch sensations from the body.
  • Most of the parietal lobes are made up of association areas.
  • Association areas: any area associated with receiving sensory information or coordinating muscle movement.
III. Occipital Lobe
