Wundt's technique of introspection can be classed as scientific as it marked the separation of modern scientific psychology from its broader philosophical roots.
Recorded introspections within a controlledlab environment and standardised procedures so that all participants received the sameinformation and were tested in the same way.
For this reason, Wundt's research can be considered a forerunner to the laterscientificapproaches in psychology that were to come.
Wundt's technique of introspection may be classed as unscientific as it is criticised for being subjective.
Wundt relied on participants self-reporting their 'private'mental processes, however, such data is subjective, and participants may not have wanted to reveal some of the thoughts they were having.
They would also not have had exactly the samethoughts every time, so establishing general principles wouldn't have been possible.
Therefore, Wundt's early efforts to study the mind were naive and wouldn't meet the criteria of scientificenquiry.
