Psych 10 - Lecture 2 summary notes latest

Psych 10 - Lecture 2 Why is spacing good for learning? - - Retrieval: spacing repetitions = forgetting in between - Variability: each presentation more likely to be encoded in a slightly different state - Attention: massed repetition gets boring What does Phineas Gage's story teach us? - brain relates to behavior; location of function What are the two parts of the nervous system? - PNS and CNS. Peripheral Nervous System and Central Nervous System Define: PNS - Peripheral Nervous System: neurons that transmits information between CNS and the body's organs/muscles Define: CNS - Central Nervous System: brain and spinal cord What are the two parts of PNS? - Peripheral Nervous System: Autonomic and Somatic Define: Automatic - Self-regulated action of internal glands (involuntary) Define: Somatic - Controls voluntary movements of skeletal muscles What are the two parts of Autonomic? - Sympathetic and Parasympathetic Define: Sympathetic - arousing (flight or fight) Define: Parasympathetic - Calming Define: Sensory Neurons - carry info from sensory receptors to the CNS (touch, pain, heat, pressure) Define: Motor Neurons - carry info from CNS to muscles and glands - produce movements Define: Interneurons - connect sensory motor or other interneurons Parts of a Neuron - - Dendrite: detect incoming signals - Soma (cell body): collects/sums input, contains nucleus - Axon: transmits signals to axon terminal - Myelin Sheath: covers the axon of some neurons and helps speed up neural impulses - synapse: where neurons communicate; space in between
