What was the Blakemore and Cooper experiment?
Background and aim: The aim of this experiment was to investigate the physiological and behavioural effects of a limited visual experience and whether brain development/plasticity occurs due to experiences rather than nature.
How does Blakemore and Cooper relate to the biological area?
Blakemore and Cooper (1970) Impact of early visual experience Biological An early example of research into brain plasticity, in which evidence is put forward of the impact that the visual environment has on cats’ brains (specifically their visual neurons).
How many kittens were used in Blakemore and Cooper?
one kitten
Did Blakemore and Cooper use as few animals as possible? Yes, at least in their measuring of the individual’s neurone responses which was an invasive procedure, only one kitten from each condition was used.
Why did Hubel and Wiesel won a Nobel Prize?
Hubel & Wiesel Come to Harvard Their breakthrough discoveries about the visual system and visual processing earned them the Nobel Prize for Physiology or Medicine in 1981. Hubel and Wiesel recorded electrical activity from individual neurons in the brains of cats.
What is experience based plasticity?
Experience-Dependent Plasticity is the continuing process of the creation and organization of neuron connections that occurs as a result of a person’s life experiences. Differing life situations and circumstance influence how certain areas of the brain develop and continue to grow.
How does Casey’s study link to the biological area?
How does Casey link to the biological area? Biological because it involves trying to see whether there is a neural basis to self-regulation. This is done through fMRI scans of people who, forty years previously, had taken part in Mischel’s delay-of-gratification (marshmallow) test.
How does Bocchiaro link to the key theme?
how does Bocchiaro link to the key theme? people are as obedient now as they were in the 1960s, and that people in the Netherlands are at least as obedient as people in the USA.
What is brain plasticity psychology?
Neural plasticity, also known as neuroplasticity or brain plasticity, can be defined as the ability of the nervous system to change its activity in response to intrinsic or extrinsic stimuli by reorganizing its structure, functions, or connections.
What is Hubel and Wiesel experiment?
In their experiments, Wiesel and Hubel used kittens as models for human children. Hubel and Wiesel researched whether the impairment of vision in one eye could be repaired or not and whether such impairments would impact vision later on in life.
What was Hubel and Wiesel discover?
Hubel and Wiesel demonstrated that some neurons were only responsive to information that came from a single eye, a phenomenon they referred to as “ocular dominance”. Intriguingly, neurons that are tuned to a particular eye cluster together in anatomical columns in the visual cortex of the brain.
What is the difference between experience expectant and experience dependent?
These examples illustrate two extremes—experience expectant plasticity reflects situations in which there is high overlap in the input across individuals and experience dependent plasticity reflects situations in which there is little overlap in the input across individuals.
