Psychology explores human behaviour through four main approaches that explain why we think, feel, and act the way... Show more
Ever wondered why you change your behaviour in different groups? The social approach reveals how other people massively influence what we do, even when we don't realise it.
Conformity happens in two main ways. Informational Social Influence (ISI) occurs when you genuinely think someone else knows better, so you follow their lead. Normative Social Influence (NSI) is when you don't actually agree but go along anyway to fit in and avoid standing out.
The approach also explains social categorisation - how we automatically sort people into groups, often based on stereotypes. This mental shortcut can unfortunately lead to prejudice and unfair treatment of others.
Key Study Spotlight Asch's conformity experiments showed how people will give obviously wrong answers just to match the group - proving how powerful social pressure really is!
Your brain processes information like a sophisticated computer, but sometimes it makes systematic errors that affect how you see the world. Understanding these cognitive biases helps explain why people make seemingly irrational decisions.
Fundamental Attribution Error (FAE) happens when we wrongly assume someone's behaviour reflects their personality rather than their situation. Confirmation bias makes us seek information that supports what we already believe, whilst hostile attribution bias leads us to interpret neutral actions as threatening.
The reconstructive model of memory shows that remembering isn't like replaying a video. Instead, we use schemas (mental frameworks) to rebuild memories, often shortening, confabulating, or rationalising what actually happened.
Cognitive priming explains how certain cues trigger related thoughts and behaviours through associative, semantic, or repetitive connections in memory.
Real-World Example Loftus and Palmer's car crash study proved that even subtle word changes ("smashed" vs "contacted") can alter our memories of events!
Your behaviour isn't fixed - it's constantly shaped by environmental stimuli through different types of learning. This approach shows how we acquire new behaviours throughout our lives.
Classical conditioning creates automatic responses by pairing stimuli together. An unconditioned stimulus naturally triggers an unconditioned response, but through repeated pairing with a neutral stimulus, we develop new conditioned responses to previously meaningless triggers.
Operant conditioning uses consequences to shape behaviour. Positive reinforcement adds something pleasant, whilst negative reinforcement removes something unpleasant. Both increase behaviour, whereas punishment (positive or negative) aims to decrease it.
Social learning theory demonstrates how we learn through observation, imitation, and modelling others. Vicarious reinforcement means we learn from watching what happens to other people, not just our own experiences.
Famous Example Watson and Rayner's Little Albert experiment showed how phobias can be learned by associating neutral objects with frightening experiences!
Your biology fundamentally influences your psychology through brain structure, chemical processes, and evolutionary heritage. This approach reveals the physical foundations of behaviour and mental processes.
Neuroanatomy maps how different brain regions control specific functions. The frontal lobe handles voluntary movement, the somatosensory area processes touch sensations, and the visual area interprets what you see (sending information to the opposite brain hemisphere).
Neurochemistry focuses on neurotransmitters - chemical messengers that allow brain cells to communicate. Serotonin stabilises mood, whilst sex hormones like oestrogen and testosterone influence everything from physical development to behaviour patterns.
Evolutionary psychology distinguishes between your genotype (inherited genes) and phenotype (how environment shapes gene expression). Natural selection has shaped psychological mechanisms that helped our ancestors survive and reproduce.
Fascinating Fact Studies show men typically have larger brain volume than women, but this doesn't determine intelligence - it's about how efficiently neural networks function!

The app is very easy to use and well designed. I have found everything I was looking for so far and have been able to learn a lot from the presentations! I will definitely use the app for a class assignment! And of course it also helps a lot as an inspiration.

Wow, I am really amazed. I just tried the app because I've seen it advertised many times and was absolutely stunned. This app is THE HELP you want for school and above all, it offers so many things, such as workouts and fact sheets, which have been VERY helpful to me personally.

Just amazing. Let's me revise 10x better, this app is a quick 10/10. I highly recommend it to anyone. I can watch and search for notes. I can save them in the subject folder. I can revise it any time when I come back. If you haven't tried this app, you're really missing out.

This app has made me feel so much more confident in my exam prep, not only through boosting my own self confidence through the features that allow you to connect with others and feel less alone, but also through the way the app itself is centred around making you feel better. It is easy to navigate, fun to use, and helpful to anyone struggling in absolutely any way.

I know a lot of apps use fake accounts to boost their reviews but this app deserves it all. Originally I was getting 4 in my English exams and this time I got a grade 7. I didn’t even know about this app three days until the exam and it has helped A LOT. Please actually trust me and use it as I’m sure you too will see developments.
