Reaction rangeCurrent LectureThe Brain Hemispheric Lateralization Left Brain: right side of the body/ “approach” emotions such as joy, interest, & anger / languageprocessing/ speech Right Brain: left side of the body/ visual – spatial information/ non-speech sounds/ passion/ creativity Neurons & Synapses - Send and receive information (constant communication)- Born with most of their neurons, however connections have not been madePart of Neuron: These notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute.Myelination: processing and then responding, padding around the neuron that adds more speedy transition Axon: what sends information to others, builds up over time (picture an empty toilet rolland then over time the toilet paper roll gets bigger and bigger more toilet paper gets added to it)Synapse: makes connection between axon and dendrite, will become perminate- Synaptogenis: producing synapse, from birth to 2 years, - Synaptic pruning – gets rid of extra neurons and synapses, will help the brain to become stronger and make stronger connections Brain Development & Experience- Experience – expectant processo Our brain expects stimulation: touch, taste, hearing, seeing, and smelling- Experience – dependent processo How our brain experiences stimulation, growing up in a city vs. rural town, growing up with music in the home or with a full stocked libraryMirror Neurons and the Social Brain “Monkey sees money do neurons” - Idea that we are able to feel what others feel just by looking at them - Neurons translating so we can relate to the world- To help with empathy, we have to have theory of mind – the theory that we are able to process that other people feel different emotions than what we are feeling- Mirror neurons allow empathy - Language - Important to understand actions & intentionsGenetics & Social Development - Human Behavior Geneticso Heritability Factor- Genotype – what you are made up of, your DNA- Phenotype – observable characteristics, portion of the gene that is expressing themselves- Genes can be “turned on” throughout lifeMethods of Studying Genetics in Development - Adoption Studies – Compare adopted children to biological and adoptive parents - Twin Studies – compare similarities between identical twins (share 100% of genes) and fraternal twins (50% of shared genes) - Reaction Range – the range of possible developmental outcomes established by a person’s genotype in reaction to the environment o Can be shifted dependent of traitso *Reaction range example provided in Social Development book- Canalization – least susceptible to environmental influence, would be child “A” in
