THINKING SKILLS

2. o OVERVIEW:
 Pilot study.
 Sleep.
 Thinking skills.
 Materials & methods.
 Results and findings.
 Discussion.
 Conclusion & recommendations.

3. PILOT STUDY ?
 A pilot study, pilot project, pilot test, or pilot experiment is a small
scale preliminary study conducted in order to evaluate feasibility, time,
cost, adverse events, and improve upon the study design prior to
performance of a full-scale research project.
 Pilot experiments are frequently carried out before large-
scale quantitative research, in an attempt to avoid time and money
being wasted on an inadequately designed project.
 A pilot study is usually carried out on members of the relevant
population, but not on those who will form part of the final sample.

4. SLEEP.
 Sleep is a naturally recurring state of mind and body, characterized
by altered consciousness, relatively inhibited sensory activity,
inhibition of nearly all voluntary muscles, and reduced interactions
with surroundings.
 We spend about 30% of our time doing it.
 Quality sleep – and getting enough of it at the right times is as
essential to survival as food and water.
Without sleep we can’t form or maintain the pathways in your brain
that let us learn and create new memories, and it’s harder to
concentrate and respond quickly.

5. THINKING SKILLS:
Thinking Skills are mental processes we use to do things like:
solve problems, make decisions, ask questions, construct
plans, evaluate ideas, organise information and create objects.
Cognitive Thinking Skills.
Strategic/Reflective Thinking Skills.

6.  MATERIALS AND
METHODS:Questionnaire (Questing 20 peoples about past experiences on
performance in tests/examinations .
The sample ( 20 peoples) were divide into 2 groups (each group 10
peoples):
I. Got enough sleep group (A, Non-exposure)
II. Insufficient sleep (little /deprive) group (B , exposure)
Based on assessing 7 criteria (Retrieving, Understanding, Organising
gathered information, Deciding, Analysing, Evaluation ,Thinking
speed ) for each group individually.
And coding Impaired as 1 and Non-impaired as 0 in Excel Sheets.

7.  RESULTS AND FINDINGS:
I. Got enough sleep(Non-exposure A) ; Analysing of the seven criteria
result ; has shown no significant impairment (3%).
II. Insufficient sleep group (exposure B) there is significant
impairment ( 26.5%) .

8.  DISCUSSION:
 The important finding of this study were that sleep has significant
effect in human thinking skills since there impairment in the seven
thinking skills assessing criteria designed for the study in group
insufficient slept ,and this can be useful to prove important of the
sleep over sleep deprivation for reviewing or study.

9.  CONCLUSION AND
RECOMMENDATIONS :
The instrument has developed to measure thinking skills based on the
seven criteria was validated by experiments since group A has shown
there no significant importance in contras group B has shown
significant finding .Hence it will be highly reliable instrument to study
both types of thinking skills (cognitive and strategic/reflective).
A real study with a large sample size can be conduct based on the
instrument. And assessing of brain chemistry may will give more
understanding of who sleep effect in our Thinking skills
physiologically .
