Desensitisation, Disinhibition & Cognitive Priming in Aggression
The Numbing Effect: In desensitisation, the primary manifestation is a lack of empathy for victims. Because the observer no longer feels the physiological 'sting' of witnessing violence, they are less likely to intervene in real-life aggression or feel sympathy for those harmed.
Justification and Reward: Disinhibition is most powerful when the media violence is justified (e.g., a hero getting revenge) or rewarded. This sends a message that the social consequences of aggression are positive rather than negative, effectively 'unlearning' the social inhibition against violence.
Cue-Triggered Responses: Cognitive priming manifests when environmental cues (like seeing a weapon or a specific type of confrontation) trigger the retrieval of an aggressive script. This process is often automatic and occurs without the individual consciously deciding to be aggressive.
| Feature | Desensitisation | Disinhibition | Cognitive Priming |
|---|---|---|---|
| Primary Focus | Physiological/Emotional | Social/Moral | Cognitive/Memory |
| Mechanism | Reduced SNS arousal | Weakened social norms | Activation of scripts |
| Result | Numbing/Lack of empathy | Increased acceptability | Automatic aggressive response |
| Key Factor | Frequency of exposure | Justification of violence | Environmental cues |
Desensitisation vs. Disinhibition: While both involve becoming 'used' to violence, desensitisation is about the feeling (or lack thereof) and physiological response, whereas disinhibition is about the judgment of whether the behavior is socially acceptable.
Priming vs. Learning: Unlike Social Learning Theory, which focuses on the acquisition of new behaviors, cognitive priming focuses on the activation of pre-existing mental scripts by specific cues in the environment.
Identify the Mechanism: In exam scenarios, look for specific keywords. If the scenario mentions 'heart rate' or 'lack of sympathy,' focus on desensitisation. If it mentions 'feeling it's okay' or 'justified,' focus on disinhibition. If it mentions 'reminded of a movie' or 'automatic reaction,' focus on priming.
AO3 Evaluation Points: Always consider individual differences; not everyone who plays violent games becomes aggressive, suggesting that personality traits (like the 'Dark Tetrad') or free will mediate these effects.
Prosocial Applications: A high-level response will mention that these mechanisms can be used for good. For example, 'prosocial priming' can encourage helpful behavior by exposing individuals to media where cooperation is rewarded and scripted.
Check for Determinism: Be careful not to imply that media exposure guarantees aggression. Use phrases like 'increases the likelihood' or 'lowers the threshold' to reflect the probabilistic nature of these psychological theories.
