解題
The evolutionary explanation of aggression suggests that aggressive behaviors are adaptive traits that evolved to enhance survival, secure resources, and ensure reproductive success. According to this theory, males who were successfully aggressive could defend resources, secure territory, and protect their mates and offspring, thereby passing on their aggressive genes to future generations. Another aspect of this explanation is mate retention and paternal uncertainty; males use mate retention strategies, including physical and psychological aggression, to prevent cuckoldry (raising another man's child) and ensure their own genes are passed on. Male-male competition is also highlighted, where physical aggression is used to establish dominance status, making them more attractive to females. However, a significant limitation of the evolutionary explanation is that it is post-hoc, meaning it reconstructs evolutionary history to explain current behavior. Because we cannot directly observe human behavior from thousands of years ago, these hypotheses are difficult to test empirically and are largely unfalsifiable. Furthermore, this explanation is highly reductionist as it reduces complex social behaviors entirely to genetic and evolutionary survival mechanisms, ignoring environmental and cultural influences. For example, social learning theory suggests aggression is learned through observation and imitation of role models, which is supported by Bandura's Bobo doll studies. Additionally, there are alternative biological explanations that have stronger empirical support, such as the role of the amygdala and prefrontal cortex in emotion regulation, or high levels of testosterone, which can be measured directly using brain scans or saliva tests. Finally, evolutionary explanations can be criticized for being socially sensitive, as they can be misused to justify domestic violence or male violence as 'natural' or 'evolutionary adaptive' behaviors.
評分準則
Marks are awarded as follows: 4 marks for AO1 (Knowledge and understanding), 4 marks for AO3 (Evaluation and analysis). AO1 Indicative content: Evolutionary theory suggests that aggression is an adaptive response that increases survival and reproduction chances; aggression is used to protect and acquire scarce resources such as food, territory, and shelter; male-male competition involves displaying aggression to establish social hierarchy and attract mates; paternal uncertainty leads to evolutionary mechanisms like mate retention strategies and jealousy to prevent cuckoldry. AO3 Indicative content: Evolutionary explanations are post-hoc and unfalsifiable, as we cannot scientifically test or recreate prehistoric selective pressures; this approach is biologically reductionist, ignoring modern environmental, cognitive, or cultural factors that dictate aggressive responses; alternative theories, like Social Learning Theory (Bandura), demonstrate that aggression can be rapidly learned through modeling, rather than just evolved; stronger biological support exists from neuroimaging studies (e.g., Raine et al., 1997), which show localized brain dysfunction (prefrontal cortex/amygdala) in aggressive individuals, providing more objective, empirical evidence; the theory has negative social implications as it might normalize or excuse aggressive or abusive behaviors as natural evolutionary adaptations. Marking Grid: Level 1 (1-2 marks): Isolated elements of AO1 knowledge and simplistic AO3 evaluation. Level 2 (3-4 marks): Some accurate AO1 knowledge and basic AO3 evaluation points. Level 3 (5-6 marks): Mostly accurate AO1 knowledge and developed, logical AO3 evaluation points. Level 4 (7-8 marks): Precise and comprehensive AO1 knowledge and highly structured, balanced, and critical AO3 evaluation.
