Evaluate the methodology of Kohlbergs study: The Child as a Moral Philosopher
+ One strength of Kohlberg’s study is its use of longitudinal design. For example, Kohlberg followed 75 American boys over a period of 12 years, assessing them at three year intervals. This approach allowed the researchers to observe changes in moral reasoning as the same individuals matured, enhancing the internal validity by tracking development over time rather than comparing different individuals at different ages.
+ Another strength is the inclusion of cross, cultural data. For example Kohlberg collected data from participants in various countries, including the UK, Taiwan, Mexico, Canada and Turkey. By examining moral reasoning across diverse cultural contexts, Kohlberg aimed to establish the universality of his moral development stages, increasing the study’s cross-cultural validity
- A weakness of the study is the use of gender/race biased sampling. For example, Kohlbergs sample consisted solely of 75 American males from predominantly middle-class backgrounds. This lack of diversity reduces the generalisability of the findings since it doesn’t represents females or individuals from other socio-economic or cultural backgrounds.
- another weakness of the study is the hypothetical moral dilemmas. For example, participants were asked how they would respond to scenarios like the Heinz dilemma, rather than how they had acted in real life situations. This is a weakness since it reduces the ecological validity of the study since hypothetical responses don’t always correlate with real world moral behaviour
Evaluate the procedure of Kohlbergs study: The Child as a Moral Philosopher
+ Use of standardised moral dilemmas, which increases reliability. For example, Kohlberg presented all participants with the same set of hypothetical dilemmas, such as the famous Heinz dilemma, to assess moral reasoning. The use of consistent scenarios means that all ppts are exposed to the same stimuli, making the study replicable.
+ Use of semi-structured interviews to gather data. For example, Kohlberg asked ppts open ended questions about moral dilemmas, allowing them to explain their reasoning rather than just choosing from fixed responses. This is a + because it provides rich, descriptive data that can reveal the cognitive processes behind moral reasoning. The flexibility of the interviews ensures that ppts can elaborate on their thought processes, increasing the internal validity of the study.
- procedure is also vulnerable to demand characteristics, potentially reducing the internal validity of the study. For example, ppts (particularly those interviewed repeatedly) may have altered their responses to appear more morally advanced or socially desirable. This social desirability bias can distort results, as ppts might give answers they believe the researchers expect, rather than expressing genuine moral reasoning. The repeated measures design increases the risk or ppt reactivity, which may influence the accuracy of the data collected
- may lack practical application due to its focus on moral reasoning rather than behaviour. While Kohlbergs study explored how individuals think about moral issues, it doesn’t observe how they act in moral situations. This theoretical focus means that the study doesn’t directly inform how moral development manifests in behavioural outcomes. This may reduce the ecological validity of the study limiting its utility in predicting real world moral actions.
Evaluate the ethics of Kohlbergs study: The Child as a Moral Philosopher
+ ppts gave informed consent to take part in the research. For example, consent was given from the parents/legal guardians of the ppts since they were minors. This is a + because it ensures ppts (or their guardians) were aware of the study’s purpose and procedures before participating.
However a - ethical issue with the study is the potential for psychological harm, as the dilemmas presented might have caused emotional distress. For example some of the moral dilemmas, like the Heinz dilemma involving theft to save a life may have made the ppts feel uncomfortable or guilty about their moral reasoning. This is a - since it can cause psychological harm to the ppt, compromising their emotional well being.
