,Lecture 1: The Science of Psychology
What is psychology? → study of the soul
Humans are intuitive psychologists
Psychology is a science, it is the study, through research of mind, brain and behavior
→ aimed at understanding and predicting
- Behaviour (actions)
- Mind (mental activity)
What is mind?
- Stuff of thought
- Mental activity
- Perceptual experiences (sights, smells, tastes, sounds and touches)
- Memories, thoughts and feelings
→ Not directly observable, the observable is the tip of the iceberg
Psychological science
Levels at which you can study psychology:
● Groups vs individuals
● Behavior vs brain activity
● Nature vs nurture
Journey through the history of psychology
- Dualism (Descartes, separation of mind and body)
- Nature/nurture debate
Structuralism: complex mental processes can be reduced to simpler processes (reaction times,
introspection)
Functionalism: concerned with the adaptive purpose/function of mind and behavior (the mind
is more complex than its elements)

,Evolution
● Genetic diversity
○ Mutation = variation
○ The benefits of sexual reproduction
● Environmental pressures
○ Evolution has no foresight
● Sexual selection
○ Traits that aid in reproduction
→ Evolution can provide answers to the ‘why’ questions
Schools of thought
● Psychoanalytical approach
○ Mental processes operate below the level of conscious awareness
○ Unconscious drives
● Behaviorism
○ Building on work of pavlov
○ Only observable behavior can be subject of scientific investigation
● Gestalt
○ A few basic principles guide visual perception
○ These explain how visual input is grouped into a coherent whole
○ ‘’The whole is bigger than the sum of its parts’’
● Humanistic psychology
○ An approach focusing on basic goodness in people, achieving goals and finding
fulfillment
○ Positive psychology
○ Values, creativity, quality of relationships, gratitude, faith
● Cognitivism
○ The cognitive revolution
■ Exploring mental process
■ Influences by the progress in computer science
○ Cognitive neuroscience
■ We can infer how the mind works by looking at behavior
■ Neuroimaging has even made the mind observable

,The Scientific Method
Based on the experience, observation, existing theories etc., come up with a question and a
prediction → test that prediction against real measurement from the physical world → make
conclusion with regard to your questions, show support or lack of if for your prediction
- The SM is important because our intuitions and even perceptions can be biased. SM can
help overcome these problems.
Optimism bias: we tend to think we are better than others
Availability heuristic: If something is easier to bring to mind/image or if we hear about
something more often → we judge it as more probable
Contemporary psychology: what’s new in psychology?
➢ Biology (evolution)
➢ Big data, computational modeling
➢ Çulture
➢ Interdisciplinary influences
Lecture 2: Learning
Overview
● How do we learn
● How do we learn predictive associations?
● How do consequences of actions shape behavior?
● What do different types of associative learning have in common?
● How do we learn from others?
Learning goals
- Define classical conditioning and give examples of how it works
- Define operant conditioning and give examples of how it works
- Describe how learning takes place through observation
Learning: Environment is never constant, individuals must adapt to ever-changing conditions of
the specific environments they live in
- Behaviourism
- Ecological perspective
- Learning is an enduring change in behavior that results from experience

,2.1 Non-associative learning
Imagine a stimulus that triggers behavior, like airplane noise annoys you
Repeated exposure to his stimulation can either:
- Decrease behavior: habituation, you get used to it
- Increase behavior: sensitization, you get even more annoyed
2.2 Associative learning
We learn connections between things
- Things that happen close in time
- Behavior that has a predictable outcome
Reflexes: stimulus (S) → response ( R)
Types of learning
● Classical conditioning
○ Responding to stimuli
○ Learning process that creates new reflexes from existing reflexes
A reflex is a simple, automatic, stimulus response sequence mediated by the nervous system
=unconditioned stimulus
=unconditioned response
5
, ‘Food’ reflex:
-Stimulus: image of delicious food
-Response: hunger sensation, salivation
Creating new reflexes
- Pair a new (neutral stimulus) with the unconditioned stimulus triggering an
unconditioned response
- The neutral stimulus becomes the conditioned stimulus and the unconditioned response
becomes a conditioned response
For a stimulus to be conditioned it must have a predictive value
- Precede the unconditioned stimulus
- Signal increased probability
- Repeated pairings
- There must not already be a better predictor
How long does it last?
Extinction
- Repeated exposure to the conditioned stimulus without the Unconditioned stimulus
may make the conditioned response disappear
Conditioning and evolution
- Classic behaviorist view: humans and animals start as a blank slate, a tabula rasa
- Any stimulus pair leads to conditioning equally easy
- The contemporary view
- Conditioning occurs most easily for stimulus pairs that are relevant for survival
- You easily associate a taste with sickness, a conditioned taste aversion
- You less easily associate a sound with sickness
A phobia is an acquired fear that is out of proportion to the real threat of an object/situation
Addiction and conditioned drug effects
- Relapsing: environmental cues trigger cravings
