Document Summary
Goal: predict one variable based on another: experimental methods. Correlation does not equal causation: can be reverse causal, third variable which effects both. Inferring causality: experiments involve random assignment, this is to eliminate effects of third variables. Confounding variable (great way to critique - podcast papers?: another variable that correlates with iv which could also be a cause, solution: control for this variable. The neuron: low intensities, slow ring, high intensities, fast ring, synapse (the gap between neutrons where neurotransmitters are sent into, neurotransmitters. Excitatory - increases chance that next neuron will re. Inhibitory - decreases chance that next neuron will re. The brain: cortex divided into 4 areas. Frontal - reasoning, planning emotions, continues developing up to late 20s or. Parietal - perceptions of touch, pressure, temperature, pain, Occipital - vision: two key principles of cortical functioning. Contralaterality: receptive and control centres for ones side of body controlled by opposite hemisphere. Right- geometric patterns, faces: localizing brain function.
