Wundt contributed to psychology significantly by conducting his research in carefully controlled conditions.
Scientific - Evidence
All introspections were conducted in the lab to eliminate extraneous variables. Furthermore, procedures were standardised so all pps received the same information.
Scientific - Explain/Link back
Wundt's approach encouraged later researchers to follow the same experimental approach allowing psychology to be recognised as scientific.
Subjective - Point
On limitation of introspection is that Wundt's research today would be considered unscientific.
Subjective - Evidence
Wundt relied on participantsself-reporting their mental processes. Such date is subjective rather than being objective. Furthermore, some pps may have hidden their thoughts due to social desirability.
Subjective - Explain/Link back
Therefore, it suggests that Wundt's efforts to study the mind were flawed and would not meet the scientific criteria today.
