PSYCH 223 - Chapter 1: Introduction Flashcards
Lifespan Development Definition
The scientific study of patterns of growth, change, and stability in behaviours that occur throughout the entire lifespan.
Lifespan Milestones
Age-related differences
Lifespan Areas of Study?
Physical Development
Cognitive Development
Personality and Social Development
Are age ranges fixed for development?
No, they can vary depending on research and cultural context.
Types of Influence
- Universal Changes
- Individual Specific Changes
- Group Specific Changes
What’s the Cohort Effect?
A group specific change that is shared within a group because they share time and space.
Cohorts?
A group of people born around the same time in the same place.
Continuous Change vs. Discontinuous
Continuous: gradual change, cumulative, quantitative
Discontinuous: distinct stages, qualitative
Critical Period
Events that have the greatest IRREVERSIBLE consequences.
Sensitive Period
Susceptible to some changes, but can be undone.
Gene and Environment Interaction
Genes influence a person’s environment and vie-versa.
What is a Theory?
Explanations and prediction about the phenomena of interest.
Six Main Perspectives of Development
- Psychodynamic
- Behavioural
- Cognitive
- Humanistic
- Contextual
- Biological/Evolutionary
Psychodynamic
Sigmund Freud: Conflicting unconscious behaviours and the inner self.
Psychosexual Development
Pleasure/gratification focus on different body parts. Fixation: behaviour arising from unresolved conflict on the sexual stage.
Erik Erikson - Psychosocial Theory
Stages of life are marked by an existential crisis.
Behavioural
Development can be understood through observable behaviour and stimuli in the environment.
Classical Conditioning
- Pavlov and Watson
- An organism responds in a particular way to a neutral stimulus that normally does not bring about that type of response
- Pavlov’s dog and Little Albert
Classical Conditioning - Extinction
Conditioned associations can fade if not reinforced, the learnt response is lost.
Classical Conditioning - Generalisation
Conditioned associations can be extended to other similar stimuli.
Operant Conditioning
- B.F Skinner
- Type of learning where voluntary responses are strengthened or weakened by positive or negative consequences respectively.
Operant Conditioning - Reinforcement
Introduction of stimuli that are likely to increase the probability of certain behaviour.
Operant Conditioning - Punishment
Introduction of stimuli that are likely to decrease the probability of certain behaviour.
Operant Conditioning - Behaviour Modification
A formal technique used for promoting the frequency of desirable behaviours and decreasing the frequency of undesirable behaviour.
