Unit 1 and 2 Revision Slides Flashcards
Describe three key differences between psychology, psychiatry and social work
Psychology requires 4 years of study compared to Psychiatrists who require 6 years of study. Psychiatrists can also prescribe medication whereas Psychologists and social workers cannot. Social workers work more with the community and people facing situations such as poverty
Explain the nature-versus-nurture debate and provide an example
The ongoing debate of whether human personalities are inspired by nature which is genes or nurture which is the environment and influence of people around us
Explain the philosophical debate between free will and determinism
Free will is when a person makes a conscious decision, however, determinism is where actions are governed by others outside a persons control
Describe the mind-versus-body debate with reference to René Descartes
- Psychologists question whether the mind is a separate entity from the body and brain
- The mind relates to consciousness and self-awareness and cannot be measured
- The brain and body can be measured in terms of mass, density, shape and size
- Rene Descartes viewed the body as two separate entities - dualism. He believed our mind created our existence - ‘I think therefore, I am’
Summarise the beliefs of Claudius Galen and Franz Joseph Gall
- Galen believed the brain played an important role in sensation
- He observed people who suffered strokes or could lose a particular sense even if there was no damage to the sensory organ.
- Franz Gall believed mental abilities and personality were controlled by 27 areas of the brain supposedly located on the surface of the brain
Explain phrenology with reference to Franz Gall
- The study of lumps, bumps and indentations to determine a persons character, intelligence and a range of other behaviours and functions
- Development later led to the localisation of function
Discuss the contributions of early brain experiments by Pierre Flouren’s
- Localised areas of animals brains to observe the effect of their behaviour and cognition
- The cerebral cortex was responsible for higher order thinking and the cerebellum was involved in regulating movement
Identify PET and what it is
- Positron Emission Tomography - it tracks a radioactive substance, such as glucose that has been injected into a persons bloodstream
Identify MRI and what it is
- Magnetic Resonance Imaging - involves harmless magnetic fields and radio waves that produce a computer-enhanced image of the brain structure
Identify fMRI and what it is
- functional Magnetic Resonance Imaging - monitors blood flow and oxygen consumption to reveal areas of greater brain activity
Identify EEG and what it is
- Electroencephalograph - detects and records electrical activity in the brain in the form of brainwaves
Explain the difference between the central nervous system and the peripheral nervous system.
- CNS comprises of the brain and spinal cord. It controls the body via messages sent from the peripheral nervous system which includes nerves and ganglia located outside the brain and spinal cord
Describe the autonomic nervous system
- Responsible for communications between non-skeletal muscles and internal organs; for example, heart rate and digestion
Explain what happens in the fight-flight-freeze response
Flight - a person removes themselves from a stressful situation
Freeze - fails to react
Fight - reacts in a combative manner (fight)
Explain the role of the somatic nervous system
- Sends sensory information into the CNS and carries motor movement commands from the CNS to the skeletal muscles
What are the Dendrites responsible for in a neuron?
- Receive sensory information from other neurons via synapses and deliver this to the soma
What is the Soma responsible for in a neuron?
- The cell body
- Controls maintenance of the cell
What is the Axon responsible for in a neuron?
- Carries information from the soma towards other cells in contact with the neuron
What is the Synapse?
The function between two neurons
Explain the difference between a sensory and a motor neuron
- Carry nerve impulses towards the brain and spinal cord
- Motor neurons carry the impulses away from the brain and CNS to the relevant body parts to cause movement
Describe an interneuron
- Carries information between sensory and motor neurons
Describe what the cerebrum is responsible for (part of the forebrain)
- The biggest part of the forebrain
- Divided into the left and right cerebral hemispheres
- Contains four different regions of the brain which are responsible for higher order thinking processes
Explain the role of the midbrain
- Above the hindbrain and below the forebrain
- Responsible for the regulation of sleep, motor movement and arousal
- Connects hindbrain and forebrain
Explain the role of the hindbrain
- Consists of the medulla, pons and cerebellum
- Control breathing, heartbeat, digestion, and coordinate body movements
Describe localisation of function
- Different parts of the brain influence different behaviours or functions
Compare Broca’s area, Wernicke’s area, and Geschwind’s territory
- Broca’s area deals with speech production
- Wernicke’s area deals with speech comprehension
- Geschwind’s territory is the connection between the two
Consider the importance of myelination
- Protects axons of neurons in a child’s brain
- Aids in coordination, which also helps us in times of danger
Explain what is meant by the term pruning. In your response, reference the development of neurons in children and adults
- Unused neurons or synapses being cut down or eliminated
- Occurs during infancy and childhood but there is a second wave of pruning in early adolescence
Communicate the nature of neuroplasticity with reference to brain development (deprived and enriched environments) and brain damage
- In terms of brain damage, neuroplasticity refers to the process of reorganisation that might alter the function of a particular area of the brain
- In terms of brain development, neuroplasticity can change brain structure depending on the type of environment that development occurs in
- An enriched environment is where there is opportunity for stimulation of the brain by social and physical surroundings
- A deprived environment is where there is a lack of stimulation of the brain to encourage development
Describe Lorenz’s attachment research
- Made detailed observations of animal behaviour and was specifically interested in how attachment occurs in young ducklings and goslings
- Took a large clutch of goose eggs and kept them until they were ready to hatch
- Placed half of the eggs under a goose mother, and the other half he kept close to himself
- When eggs that were close to him hatched, he imitated the noise of a goose and the geese regarded Lorenz as their mother
- The eggs under the goose mother did the same with the goose
- Newly hatched geese will follow the first moving object they see within the 12 to 17 hour critical period after hatching
Explain the relationship between emotional development and attachment
- Assist us to develop and maintain relationships
- Allows attachment to occur
Describe Harry Harlow’s work and how it contributed to our understanding of attachment
- Focused on attachment in monkeys
- Separated infant monkeys from their mothers and raised them to good health
- He found that although these monkeys grew up healthy they were unable to socialise with other monkeys
- He provided a mother for the monkeys in the form of either a wire monkey that provided nourishment through a bottle, or a cloth mother who only provided comfort,
- He found when he scared the monkeys, those with the cloth mother would always go to their ‘mother’ for comfort, whereas those with the wire mother would no
- Feeding and nourishment do not create attachment; contact comfort is more important
Explain why John Bowlby believed that the development of attachment is biological and typical of human behaviour
- Believed reactions and behaviours of the caregiver are crucial. He stated that the development of attachment is biological and genetically inherited
- Infants cry, smile, crawl and walk to follow their mothers
Explain two attachment behaviours that an infant can demonstrate towards a caregiver
- The lack of distress when the caregiver leaves the room - insecure avoidant attachment.
- Another is when the child seeks immediate contact when a caregiver returns and is delighted when reunited with their caregiver - like secure attachment
- Another is an infant will not appear upset or cry when their caregiver leaves the room, and can even avoid them on return
Explain ‘object performance’ from Piaget’s theory
- Realising that an object still exists when it is no longer visible; for example, when a toy is covered by a blanket, knowing that it’s still there under the blanket
Explain ‘animism’ from Piaget’s theory
- Children will believe that inanimate objects are alive; for example, that their toy train is alive
Explain ‘seriation’ from Piaget’s theory
- Children will have difficulty in arranging objects according to one dimension, such as arranging sticks from shortest to longest
Explain ‘centration’ from Piaget’s theory
- Children can only focus on one aspect of a task at a time
Explain the three themes of Vygotsky’s theory of sociocultural cognitive development
- Zone of proximal development - cognitive development stretching from solo performance to collaborative cooperation; for example, a young child may not be able to wrap a present on their own but will be able to master it with assistance
- The more knowledgeable other - another individual with greater knowledge of a particular topic. With reference to the present wrapping, the person helping the child is the more knowledgeable one.
- Scaffolding - providing support to a child to help them learn and master a task independently. In the present-wrapping example, the more knowledgeable one might put the sticky tape on while the child holds the paper, as the child masters the skills on their own, the helper will do less until the child is doing the task on their own
Examine the information processing model of cognition. Refer to processing speed and cognitive strategies in your answer
- Based on the idea that humans process the information they receive
- Emphasises a continuous pattern of development, in contrast with Piaget’s theory, who thought development occurs in stages at a time
- Children who have information processing issues may have trouble with their input or output, which means that the speed of processing information for certain children can be slower
- Children learn information at varying speeds due to their ability to process their environment
- Our cognitive strategies may also slow down as we age
Assess the importance of having different perspectives on cognitive development
- There are different ways in which we develop, including the speed at which we develop.
- There are certain milestones that infants and children need to develop in order to process information, communicate, develop etc.
- Different cultures may develop differently
- One model may not explain all situations
Distinguish between selective and divided attention
- Selective attention is the ability to focus on one thing, to the exclusion of others
- Divided attention is the ability to perform two or more activities at the same time (multi-tasking)
What is EMG?
Electromyograph - detects and records the electrical activity of skeletal muscles
