What are the benifits and limitations of Cross Sectional Designs
- Benifit: Cheap, Quick, Easy
- Limiation: Exagerates results
What are the benifits and limitations of Longitudinal Research
- Limitations: Takes a loooooonnnggg time! and minimises the data
What are the benifits and limitations of Sequential Desings
Benifit: More realistic results, very efficiant and accurate in a smaller amount of time
What is the best way to measure development ?
(out of cross sectional - longitudinal - sequential)
What is wrong with coss sectional, longitudional and sequential research?
They are ALL correlational designs. We do not know the cause of why things are happening.

What effects cause people to change?
- Maturational Effects (biological)
- Cohort and Age Normative Effects
Why? Becuase they all add up over a life time
What are Maturational Effects
- Biological Effects
- things like puberty and physical development
What are Cohort and Age Normative Effects
- Cohort: A Special Subtype of age normative effects
- eg: a group of people, all around the same age experiencing a historical even together e.g Christchurch Earthquakes, 9/11
- Age Normative Effects: e.g beginning school at 5, finding a partner at 20 etc
What Are Idiosyncratic Effects?
- Unique and Individual things that change a persona to make you differnt
- e.g having many siblings.
- losing someone close to you
What is the age period of Neonates?
Newboarn to 6 weeks
What are Neonates sences like?
And how do they recognise their parents
- - are legally blind
- - very good hearing
recognise their parents by sound and feel
What can Neonates do and how do they spend their time?
Sleep 16-18 hours a day
- have very limited behavious made up of eniterly reflexes such as , sucking, graspings
What is Miolen, and why is it necessary in development of newborns
New borns have very little miolen becuase of this they have lots of reflexs. If one thing is stimulated, something else will happen. The more miolen there is the less this will happen. It gets rid of the unwanted reflexs
