Morality in Psychology Revision Notes
Defining Morality
Morality encompasses an individual's internal compass for judging actions as right or wrong. These are often principles learned through socialisation and cognitive development, guiding behaviour and decision-making in various social contexts. Understanding morality involves examining both personal conviction and societal standards.
Kohlberg's Stages of Moral Development
Lawrence Kohlberg proposed a stage theory based on cognitive development. The three levels are: (1) Pre-conventional (self-interest, avoiding punishment), (2) Conventional (conforming to social rules, maintaining order), and (3) Post-conventional (universal ethical principles, abstract reasoning). Each level contains two distinct stages, showing a progression in moral reasoning complexity.
Cognitive Development and Morality
Cognitive development, as described by Piaget, is a foundational concept for understanding how morality develops. As individuals mature cognitively, their ability to reason abstractly and take different perspectives increases, directly impacting their moral reasoning. For instance, moving from concrete thinking to more abstract thought allows for consideration of broader ethical principles beyond immediate consequences.
Evaluating Theories of Moral Development
When evaluating theories like Kohlberg's, consider strengths such as its detailed, longitudinal research and application to understanding moral reasoning. Weaknesses might include cultural bias (initial research was primarily on Western males), gender bias (Gilligan's critique), and whether moral reasoning always predicts moral behaviour. Research methods used, such as moral dilemmas, require careful ethical consideration regarding participant distress and data interpretation.
Piaget and Inhelder's Three Mountains Task (1956) Revision Notes
Aim of the Study
Piaget and Inhelder (1956) aimed to investigate egocentrism in children, which is the child's inability to see a situation from another person's point of view. They wanted to determine if children at different developmental stages could accurately perceive and describe what a doll would see from various vantage points around a three-dimensional model.
Procedure of the Three Mountains Task
Children were presented with a model of three mountains varying in size and features. A doll was placed in different positions around the model. Children were asked to choose a picture that represented the doll's view or to describe what the doll would see. Participants included children from four to twelve years of age.
Findings and Conclusion
Younger children typically showed egocentrism, describing their own view rather than the doll's. As children got older, they became more capable of taking the doll's perspective. The study concluded that egocentrism declines as children progress through the stages of cognitive development, specifically during the pre-operational stage and into the concrete operational stage.
Strengths of the Study
One strength is its detailed qualitative data, providing rich insights into children's reasoning. The study also had a standardised procedure, making it replicable, although replication efforts have sometimes yielded different results. The use of a visual, hands-on task was also appropriate for engaging young children.
Weaknesses of the Study
A key weakness is that the task may have been too complex for young children, leading to an underestimation of their abilities. Subsequent research has shown that children can demonstrate perspective-taking in simpler tasks. The sample size was relatively small and consisted of Swiss children, potentially limiting generalisability. The study's cross-sectional design means it couldn't track individual development over time.
Piaget's Theory of Cognitive Development Revision Notes
Piaget's Four Stages of Cognitive Development
Piaget proposed four universal stages: 1. Sensorimotor (0-2 years): Infants learn about the world through their senses and motor activities, developing object permanence. 2. Pre-operational (2-7 years): Children use symbols like words and images, but their thought is egocentric and lacks logical reasoning, demonstrated by issues with conservation. 3. Concrete Operational (7-11 years): Logical reasoning about concrete events develops. Children understand conservation, classification, and seriation. 4. Formal Operational (11+ years): Adolescents develop abstract thinking, hypothetical-deductive reasoning, and systematic problem-solving.
Key Concepts: Schemas, Assimilation, Accommodation, and Equilibrium
Schemas are mental frameworks that organise and interpret information. Assimilation is the process of incorporating new information into existing schemas. Accommodation involves modifying existing schemas or creating new ones when new information doesn't fit. Equilibrium is a state of cognitive balance achieved when existing schemas can explain new experiences. When new information creates cognitive conflict, disequilibrium occurs, motivating a child to accommodate their schemas to restore balance.
Evaluation of Piaget's Theory
Strengths include extensive research support for the sequence of stages, and its significant impact on education by advocating for active, discovery-based learning. Weaknesses include underestimating children's abilities, as some research suggests children can acquire skills earlier than Piaget proposed. The theory may also be culturally biased, as stage attainment can vary across cultures. It also may not adequately account for social and cultural influences on development, as highlighted by Vygotsky's theory.
