Ever wondered why psychologists approach mental health and behaviour so... Show more




Behaviourism treats humans like programmable machines - everything you do is simply learned through rewards, punishments, and associations. Skinner argued that free will is just an illusion and your environment completely controls your behaviour through conditioning.
This approach breaks down complex behaviours into simple stimulus-response patterns, making it easy to test in labs with animals. The therapies are straightforward too: systematic desensitisation helps people overcome phobias by associating fear with relaxation, while token economy systems reward good behaviour.
Social Learning Theory takes a more balanced view. Yes, we learn from our environment, but we do it through watching others and choosing who to imitate. Bandura's concept of reciprocal determinism suggests we have some free will through our ability to think about whether we want to copy someone.
Key Insight: Both approaches see us as "blank slates" shaped entirely by nurture, but SLT gives you more control over your choices.
The therapies reflect this difference - SLT uses positive role models rather than just conditioning. Both approaches use scientific methods, though SLT requires more guesswork about internal thought processes during imitation.

Cognitive psychology views your brain as an information-processing computer, focusing on how thoughts and mental schemas determine behaviour. You've got some control over your actions, but you're limited by your existing knowledge and past experiences.
Cognitive Behavioural Therapy (CBT) puts this into practice by helping people identify and challenge irrational thoughts through homework exercises and behavioural activation. It's a practical approach that gives you tools to change your thinking patterns.
The biological approach goes much deeper, explaining everything through genes, hormones, and brain chemistry. It advocates for genetic determinism - the idea that your DNA largely controls your behaviour, though the environment can still influence how genes are expressed.
Key Insight: While cognitive therapy teaches you to change your thoughts, biological treatments like SSRIs directly alter your brain chemistry.
The biological approach excels in scientific credibility with brain scans and hormone measurements, while cognitive psychology has to make inferences about mental processes we can't directly observe. Both create general laws but the biological approach is more nomothetic, assuming all humans share similar physiologies.

Psychodynamic theory suggests you're controlled by unconscious sexual drives and biological instincts, but Freud's personality structure (id, ego, superego) takes a more holistic view of behaviour. Your childhood experiences during psychosexual stages shape who you become.
Psychoanalysis uses talking therapy, dream analysis, and hypnotherapy to explore the unconscious mind. However, it's often criticised as pseudoscience because the concepts can't be properly tested or falsified.
Humanistic psychology stands completely apart by insisting you have full free will and control over your behaviour. It takes a truly holistic approach, examining how you relate to yourself (congruence), others, and society as a whole.
Key Insight: Humanistic therapy puts you in the driver's seat - the therapist provides unconditional positive regard while you direct your own healing process.
Person-centred therapy focuses on removing the "conditions of worth" placed on you in childhood, helping you develop authentic self-acceptance. Unlike other approaches, humanistic psychology deliberately rejects scientific measurement, preferring to focus on your unique, subjective experience rather than creating universal laws.

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.

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.

Ever wondered why psychologists approach mental health and behaviour so differently? Each major psychological approach has its own unique perspective on what drives human behaviour, leading to completely different therapies and explanations for the same problems.
