1. PIAGET ON PIAGET VIDEO ANALYSIS

The central idea of our theory of knowledge is almost misunderstood .some people may think one is empirical if he talks about the objection.  Meaning that human knowledge comes from what we do to objet.Give our action s are carried out on objections. hers always an interaction between ourselves and objects. Knowledge is not ready made everybody is continually creating knowledge. We are regularly organizing what we know structuring and restructuring our understanding.

Empirical think that know is a copy of objects. But it is an assimilation or intern. Best example found in child’s drawing does not draw what he sees he draws what he knows about it is his interpretation of it and not the object as it is. Copy a diamond shape he draws a square with the point some point.

We interpret according to our structure; she added three points, rather rounded Points .critique is that our knowledge is not molded directly by things we observe we enter according to our structures. For instance, the history of mathematician took a time to constructing a negative, math is knowledge observed not reperformed. If these experiences of playing as Chomsky believe it would have existed implicitly in babies and even in animals. We would have to o back to invertebrates to find the source of maths.The latter is contest constructed by our actions. In the child we can witness this from one day to next .child must create anything show a child a string it, we ask him what will happen if we pull it, he understands that if you lengthen this part, then you shorten the other.you might think that he has learned all about it.  If you ask him if the string is the same after you have pulled the end down he says no.he doesn’t subscribe to this construction. This conservation is not achieved or constructed until 7 or 8 years this show what a distance there is between what is innate and what is elaborated and built. little by little .Operational structures are systems of transaction. That can b coordinated among them. They are having internalized form of action. Coordinate into closed logic by. Example is clarification or series.the above information is also found from our chapter in the text book and is very relevant.

This is unique concept we never learn it from the chapter .Operations as transformations which are reversible e.g. addition whose inverse is substruction.We have studied structures before and after the acquisition of language. People object that a given structure exists only. In subconscious mind and not as such as in child’s mind. structure is what child knows how to and not what he thinks about it .while child does not have to own they about structure; we can observe that what he knows how to do is well coordinated.Enabling him to coordinate into the closed logical system.As the example is clarified on or serialization. Operation is transformation which is reversible.

2.SLEEP CYCLES VIDEO ANALYSIS

Marion conducted  him the researcher   using  electroencephalograph (EEG) to a to study sleep he observed his son asleep in the machine

Brain wave patterns are displayed.

TYPES OF SLEEP

1. Non-Rapid Eye Movement (NREM)
2. Rapid Eye Movement (REM) Sleep (paradoxical sleep)

Stage1.

The Beginnings of Sleep brief transition stage when the first fall asleep. Amid early stage of sleep, one is somehow awake and alert. The beta brain waves are produced by the brain small and fast. Then it starts relaxing and slowing down; slower waves called alpha waves.  None is quite asleep; there is an experience of strange and incredibly vivid sensations called hypnagogic hallucinations. For instance feeling like you are falling or hearing someone call your name. Sleep is a state marked by physiological state and process.

Stage 2.Through four successively deeper stages of sleep

Characterized by an increasing percentage of slow, irregular high amplitude delta waves the researcher watched his son sleep when he made the interesting discovery.

REM SLEEP/ACTIVE SLEEP

• in this stage one has Rapid eye movement
• Heightened brain activity much like normal brain activity physical analysis
• This is the Period when dreaming occurs.

NREM SLEEP

• Called quiet sleep
• Body slows down
• Brain waves slow down into slow wave sleep

NREM has four stages

This stage is further divided into four stages

Stage 1 alpha waves thinking about mundane events daily activities

stage 2theta waves hypnagogic hallucinations k complexes sleep spindles, this is the onset of the actual sleep, theta wave predominates slow bursts of brain activity called k complexes and sleeps spindles .one also experience hypnagogic hallucination  sleep starts the feeling of falling,

Stage 3 delta wave activity

NREM stage 3and four similar

• slow wave sleep –delta waves movement of a body still possible
• Sleepwalking occurs most often during stage 4 when a subject is virtually visible to the world in stage 4 movement is possible

After stage 4 REM SLEEP

• Visual and monitor neurons in brain repeatedly activate just as they do while awake.
• Eyes dark back and forth
• muscles actively suppressed –sleep paralysis occurs, but muscles may twitch
• heart rate blood pressure and respiration can fluctuate down
• not just sleep thinking but real dreaming occurs

CYCLING BETWEEN REM/NREM

will cycle completely through the four stages of NREM &REM again around five times a nightmare periods will become shorter REM periods will lengthen

DREAM and REM sleep

a real dream  is a vivid detailed consisting of sensory and monitors sensations experienced during Remorse thought  lacks vivid sensory and control consciousness is more similar to daytime thinking and occurs during slow sleep

Lucid dreaming.

Has little effect on the performing   tasks requiring physical skill or intellectual judgment

Hurts performance on a simple on simple, tedious tasks more than challenging ones, most positive effects are sleepiness itself.

Sleep restriction (reduction in the times sleeping)

Diminished concentration, reaction time, memory time, ability to gauge risk, emotions are   volatile, sleep restriction overtime .more accidents can occur because the motor ability diminish .subjects are less immune to colds and flu. Individual differences in sleep drive.Some particular need more and some less than the typical 8 hours per night. Insomniacs sleep far less than most but do not feel tired during the day .Insomniac have a typical desire for sleep but are unable to and feel tired during the day. The sleep cycle stages and level of brain consciousness is relevant to the chapter it is similar to what we learned in the chapter .

While this is different from what we learned from the chapter From the video restoration theory a body wears out during the day and sleep is necessary to put it back in shape .Adaptive method sleep emerged in evolution to preserve energy and protect during the time of day when there are little value and considerable danger.
