Memory and Eyewitness Testimony
Your memory isn't as reliable as you might think, especially when you're stressed or anxious. Retrieval failure happens when you can't access stored memories, often because the context has changed dramatically from when you first learned something.
Anxiety plays a massive role in how well you remember events. Moderate anxiety can actually help your memory, but high anxiety tends to make it worse. This is crucial for understanding eyewitness testimony - witnesses under extreme stress might not remember crimes accurately.
The weapon focus effect shows that when people see a weapon during a crime, they focus so intensely on it that they remember fewer details about everything else. However, research suggests this isn't just about anxiety - it's also about the weapon being unusual and grabbing attention.
The cognitive interview technique helps police get better information from witnesses by using memory cues and asking them to recall events from different perspectives. It's much more effective than standard questioning methods.
Key Point: Memory models like the multi-store model and working memory model explain how information moves through different storage systems, but real-life memory is far more complex than these simplified theories suggest.

Mental Health: OCD and Depression
Understanding mental illness involves looking at both biological explanations and cognitive treatments. For OCD , research shows genetic factors play a role - twin studies reveal 61% concordance rates for identical twins compared to 31% for non-identical twins.
Depression can be effectively treated with CBT (Cognitive Behavioural Therapy), which focuses on changing negative thought patterns rather than dwelling on past traumas. Studies show that 86% of patients improve when CBT is combined with antidepressants, compared to 81% with drugs alone.
Phobias are often explained through behavioural theories - we learn to fear things through bad experiences or by watching others. Flooding and systematic desensitisation are two main treatments that work by gradually reducing the fear response.
Defining what's "abnormal" is tricky and depends on statistical infrequency, deviation from social norms, and failure to function. What's considered normal varies massively between cultures.
Remember: Mental health treatments work differently for different people, and biological and psychological approaches often work best when combined.

Social Influence and Conformity
You're constantly being influenced by others, often without realising it. Asch's conformity studies showed that people will go along with obviously wrong answers just to fit in with the group - this happens through normative social influence (wanting to be liked) and informational social influence (thinking others know better).
Milgram's obedience experiments revealed that ordinary people will follow authority figures' orders, even when they think they're hurting someone. This happens because we enter an agentic state where we see ourselves as just carrying out orders rather than being responsible for our actions.
Minority influence can create real social change, but it requires consistency and commitment over time. Moscovici's blue-green slide study demonstrated that a persistent minority can eventually sway the majority's opinion.
You can build resistance to social influence through education and understanding how these processes work. Having social support from even one other person dramatically reduces conformity pressure.
Think About It: Social change happens when minorities stay consistent with their message and gradually win over the majority - think about how attitudes towards environmental issues have shifted over recent decades.
