Developmental psychology (option)

Paper labels are an unofficial, independently authored grouping, applied only where a question's own format genuinely matches a real paper convention (such as IB Mathematics AA's non-calculator/calculator split). They do not reproduce any exam board's real paper numbering or mark allocation, and uncertain questions are labelled general practice instead.

• 1A researcher observes that infants under 8 months old do not search for a toy that has been hidden under a blanket, while infants over 8 months old do search for it. (a) Name the cognitive milestone this describes. (b) Suggest one limitation of using observation of infant behaviour, rather than verbal report, to draw conclusions about infant cognition.Paper 2 styleMedium4 marksNo calculator+
• 2Marking analysis: A learner attempts the following task: “A researcher observes that infants under 8 months old do not search for a toy that has been hidden under a blanket, while infants over 8 months old do search for it. (a) Name the cognitive milestone this describes. (b) Suggest one limitation of using observation of infant behaviour, rather than verbal report, to draw conclusions about infant cognition.” Their response addresses only this point: “Names object permanence.” Evaluate the response against the complete 4-mark task. Identify what earns credit and state every additional requirement needed for full marks.Marking analysisMedium4 marksNo calculator+
• 3A study compares academic performance of adolescents raised with an authoritative parenting style versus an authoritarian parenting style, finding higher average performance and reported wellbeing in the authoritative group. (a) State one key difference between the two parenting styles. (b) Suggest one confounding variable that could partly explain the performance difference besides parenting style itself. (c) Explain why this study design cannot establish that parenting style alone causes the difference in performance.Paper 2 styleMedium5 marksNo calculator+

(c) Explain why this study design cannot establish that parenting style alone causes the difference in performance.” Their response addresses only this point: “States a valid key difference, such as authoritative parenting combining high demandingness with high responsiveness/warmth, while authoritarian parenting combines high demandingness with low responsiveness.” Evaluate the response against the complete 5-mark task.
