Document Summary
Consists of the differentiation of the major physiological structures and systems. The stage in which the child is most affected by outside sources. 2 months after conception and lasts until birth. Reflexes usually appear about 5 months (statle reflex seen earlier in female fetus) Eyes can open and close by 6th month. All sounds that reach womb are low pass filtered (high frequencies removed) Scientific method: identify question of interest, form hypothesis, select method for collecting data. Observation (direct or structured)- direct: researchers go into natural setting and observe behaviour. Strengths: easy to use with infants and toddler who cannot give a verbal response. Findings are most likely to reflect natural behaviour (high on ecological validity). Weakness: some behaviours are so infrequent (and / or undersirable) that they are not likely to be observed. Another weakness is that there are many things happening so can"t determine cause.
