AO1 Knowledge and Understanding:
- The biological approach suggests aggression is determined by physiological systems. High levels of the hormone testosterone are linked to aggressive and dominant behavior. Brain structures, particularly a hyperactive amygdala (which processes threat) and an underactive prefrontal cortex (responsible for impulse control and decision making), are also implicated in aggression.
- From an evolutionary perspective, aggression is seen as an adaptive behavior that evolved to secure resources, defend status, and ensure gene survival.
- In contrast, learning theories suggest aggression is acquired through environmental experiences. Operant conditioning proposes that aggression is maintained if it is directly reinforced (e.g., a child getting what they want through bullying).
- Social Learning Theory (SLT) proposes that aggressive behavior is learned through the observation and imitation of aggressive role models, mediated by cognitive processes (attention, retention, reproduction, and motivation) and vicarious reinforcement.
AO3 Analysis and Evaluation:
- The biological approach is supported by scientific, objective research. For example, Raine et al. (1997) used PET scans to show brain dysfunction in murderers pleading GSNG, giving the biological explanation high scientific credibility. However, brain imaging studies only establish correlations, not direct causal links.
- Learning theories are also supported by empirical evidence, such as Bandura, Ross and Ross (1961), who demonstrated that children exposed to aggressive adult models imitated those exact physical and verbal behaviors. However, this study was a laboratory experiment, which lacks ecological validity and may reflect demand characteristics rather than genuine aggressive intent.
- The biological approach can be criticized for biological reductionism, as it reduces complex social actions to basic physical mechanisms (e.g., testosterone levels), ignoring the situational and social triggers of aggression.
- Learning theories are deterministic in assuming that environmental stimuli or modeling inevitably produce aggression, neglecting individual genetic vulnerabilities or cognitive choice.
- Practical applications differ significantly: biological explanations have led to pharmacological treatments (such as anti-androgens or SSRIs) to manage aggressive urges, whereas learning theories have successfully underpinned behavior modification programs like Token Economies and parent training programs.
- Ultimately, an interactionist approach (e.g., the Diathesis-Stress Model) provides a more comprehensive explanation, suggesting that biological predispositions (such as low MAOA gene expression) may only manifest as aggressive behavior when triggered by an adverse environment (such as experiencing abuse or learning aggression through modeling).

Indicative content is split into AO1 (6 marks) and AO3 (6 marks).
Level 1 (1-3 marks):
- Demonstrates isolated elements of knowledge (AO1) with little or no evaluation (AO3).
- Points are unstructured and lack clarity; spelling and grammar errors may obscure meaning.
Level 2 (4-6 marks):
- Demonstrates some accurate knowledge of both the biological approach and learning theories (AO1).
- Attempted evaluation is present but limited, mostly descriptive or generic (AO3).
- The response is occasionally structured and has some logical flow.
Level 3 (7-9 marks):
- Demonstrates mostly accurate and detailed knowledge of both approaches in relation to aggression (AO1).
- Evaluation is developed, offering clear strengths and weaknesses of both approaches, with some comparative points (AO3).
- The structure is mostly logical, leading to a coherent argument.
Level 4 (10-12 marks):
- Demonstrates precise, comprehensive, and well-balanced knowledge of both biological and learning explanations of aggression (AO1).
- Evaluation is critical, balanced, and thoroughly developed, demonstrating a clear awareness of the nature vs nurture debate and methodological differences (AO3).
- Shows logical chains of reasoning, concluding with a well-formulated, balanced synthesis or judgment.
