PsychologyUnit 1 Chapter 1 – Nature of psychology
Define Psychology Psychology can be defined as the scientific study of mental processes and behaviour in humans (and animals).
What is behaviour? • Behaviour is any action that can be observed and scientifically measured. • Anything that you do that can be seen. • Make a list of five observable behaviours • They are also known as OVERT behaviours.
What is a mental process? • Mental processes are thoughts and feelings that are personal and internal and cannot be directly observed. • Make a list of five mental processes • They are sometimes known as COVERT behaviours and include • Perception • Cognition • Emotion
Perception • Perception enables us to make sense of and understand the many different stimuli in our surrounding environment
Cognition • Cognition refers to thinking and any other mental operation relating to how we process information, make plans or acquire knowledge.
Emotion • Emotion refers to an individual’s subjective response to the world around them. • Eg: How would you respond to being told that school is cancelled? • How would you respond to being told that your boyfriend/girlfriend has been cheating on you? • Each person’s response may vary due to their different interpretation of the news. • Emotion also involves physiological responses – can you think of any?
Psychology as a profession • What is a psychologist? • How do you become a psychologist? • Visit http://www.psychology.org.au to research the different types of psychologists. • CAM: Exercise 1.1
Activity • For each of the following problems decide if you would see a psychologist or psychiatrist for help. Explain your choice. • Relationship issues • Bipolar disorder • Frequently experiencing intense rage • Eating disorder • Problems falling asleep at night – short term • Clinical depression • An irrational fear of spiders • Suffering anxiety about starting at a new school • Poor self esteem • Grieving over the death of a friend

Classic Perspectives and Theories • Each of the following perspectives had its own theories of behaviour and mental processes. They all differed in three main ways: • Their focus of study • Their method of study • Their theories • There are five different theories (complete LA 1.10).
Structuralism – Wilhelm Wundt (1832 – 1920) • Interested in the study of human consciousness • Considered ‘radical’ because consciousness can’t be directly observed. • Focuses on the structure of the consciousness, how the parts are organised and how they are interpreted. • Used ‘introspection’ to study consciousness – requires participants to reflect on their thoughts and other mental experiences.
Functionalism – William James (1842 – 1910) • Focuses on studying the purpose that mental processes serve in enabling people to adapt to their environment. • Interest in how and why our thoughts and feelings lead us to behave as we do.
Psychoanalysis – Sigmund Freud (1856 – 1939) • Focuses on the roles of unconscious conflicts and motivations in understanding and explaining behaviour and mental processes. • We are not usually aware of what is going on in our unconscious because it is hidden from our conscious awareness. • Also, our past experiences are very important in the development of our personality and behaviour.
Behaviourism – John B. Watson (1878 – 1958) • Involves understanding and explaining how behaviour is learned and moulded by experience. • According to behaviourists, we tend to repeat behaviours that we find rewarding in some way and avoid those we associate with punishment.
Humanism – Carl Rogers (1902 – 1987) • An approach to understanding and explaining behaviour and mental processes that focuses on the uniqueness of the individual person and the positive qualities of all human beings to fulfil their lives. • Assumption that all people are born good and that we strive to reach our full potential, whatever that might be.
Contemporary Perpectives • Each of the classic perspectives have influenced the following contemporary perspectives of psychology: • Biological perspective • Behavioural perspective • Cognitive perspective • Socio-cultural perspective • Each represents a different point of view about human behaviour and mental processes.
Biological perspective • Focus on the biological influences on behaviour and mental processes, including the brain and the rest of the nervous system, the endocrine system, the immune system and genetics. • All our thoughts, feelings and behaviours are associated with underlying bodily activities and processes. • Michael Gazzaniga (2006) – three major developments within biological perspective via split-brain surgery: • Brain chemistry • Genetics • Technology to study human brain
Behavioural perspective • Focus on how behaviour is acquired by environmental consequences such as rewards and punishments • All behaviour can be explained in terms of learning processes. • Origins in Watson’s behaviourism • Will learn more in the Area of Study - Learning
Cognitive perspective • Focus on how we acquire, process, remember and use information about ourselves and the world around us. • How we take in information in order to think, feel and behave as we do. • Assumption is that internal mental processes are important in their own right. • It is essential to know what is going on inside one’s mind to know what makes one ‘tick’.
Socio-cultural perspective • Focus on the roles of social and cultural influences on human behaviour and mental processes. • Assumed that socio-cultural factors such as sex, race, age, income level and the culture in which people grow up are important influences.
Scientific Nature of Psychology • Scientific method refers to the systematic approach for planning, conducting and reporting research which involves collecting empirical evidence (data collected directly by observation or experimentation). • Empirical evidence allows to draw accurate conclusions which are most likely to be free from personal biases. • Research must also be able to be replicated, therefore, making the results reliable if similar results are obtained from first research. • Copy fig 1.30, page 38
Science Vs Non Science • Psychology uses a scientific approach when conducting research. This enables psychologists to draw valid and reliable conclusions about the behaviour and mental processes they study. • Other ways to explain human thoughts, feelings and behaviours that are not based on science – these are pseudo-sciences or fake sciences. • Astrology • Numerology • Graphology • Palmistry
