Psych Week 4 SSN Social Influence  Conformity- compulsion to conform to what others are doing subconsciously. Asch’s Conformity Experiment o 3 confederates working with researcher with one participant  Obedience- obeying an order that an authority figure gives you. Milgram (1965.1974) o 3 confederates, One participant: Teacher (Participant), learner (confederate), and researcher Stanford Prison Experiment- was supposed to last 2 weeks, but only last 3 days due to prisoners experiencing mental meltdowns, and other factors.  Deindividuation- responsibility has been given to the group o Anonymity- lack of outstanding, individual, and or unusual features; impersonality.  Social loafing- part of a group and only part effort is put into solving a problem. o Make sure that the participants in a group know that their contribution does matter.  Groupthink- part of a group, pressure on the group to get something done (keep the peace, rather than vocalize issues or opinions) o Conformity over accuracy  Prejudice- judgement/ negative attitude for a group of people. o Explicit racism- direct relationship between attitude and behavior o Implicit racism- having attitude not easily linked to behavior.  Discrimination- action/act of prejudice- negative behavior. Causes:  Competition and limited resources  In-group/outgroup  Stereotypes  Heuristic Chapter 2:  Phrenology- different parts of the brain is responsible with different personality traits. o Each responsible for certain actions o It would cause physical lumps- if you did not use that part.  Neuron- moves information to different areas.  Glial cells- helps the neurons  Dendrites- tree like- collects information from other cells  Cell body- life support  Axon- passes messages away from the cell body to other neurons  Myelin sheath- cover the axon of some neurons and helps speed neural impulses.  Action potential- neural impulses that travels down an axon like a wave. o When it starts positives go to the inside of the axon 2 o This is referred to as an electrical charge.  All-or-nothing response- it either fires or it does not; more stimulation does nothing.  Neurotransmitters- name of chemical that goes across the synapse o Ach- makes our muscles move (Also it is used for memory)  Reuptake- making those neurotransmitters by pulling them into the neuron that released them.  Refractory Period- a neuron cannot send another action potential for a brief period of time. How drugs and other chemicals alter neurotransmitters  Agonist- molecule that increases a neurotransmitters action  Antagonist- molecule that inhibits or blocks a neurotransmitters action Types of Neuros:  Sensory- outside world- pain caused  Motor- interactive, muscle movement  Interneurons- connect sensory and motor neurons Autonomic Nervous System Subdivisions  Sympathetic Subdivision: o fight or flight o dilated pupils to retain more information o turns off digestion o increased heart rate  Parasympathetic subdivision: 3 o Collect energy and stores it  Somatic: Soma=Body o Controls body movement  Endocrine System (Hormones) o Feedback system:  Brain>pituitary>other glands> hormones> body and brain  Hormones- travel a long distance and through the blood.  Neurotransmitters- usually travel through the synapse.  Hypothalamus- brain region controlling the pituitary gland- telling it what it should release.  Pituitary gland- secretes many different hormones, some of which affect other glands.  Adrenal gland- helps trigger “fight-or-flight”  Pancreas- regulates the level of sugar in the blood – insulin The brainstem and Thalamus  Medulla- breathing, heartbeat, temperature control  Pons(bridge)- bring information to different parts of the brain  Cerebellum- “little brain”- pons connect two halves- this part of the brain deals with balance and learning  Reticular Formation- arousal  Thalamus- part of forebrain- transferred sensory neurons to other parts of the brain. Limbic System: Emotion 4  Amygdala- emotions that are usually negative: anger, fear  Hippocampus- memory The Cerebral Cortex  Frontal: controlling of inhibitions, “self-control”, personality, logic  Parietal: skin senses; putting sense together  Occipital: seeing/ vision  Temporal: hearing (hippocampus lies here) Left hemisphere is for logic, speech, and tiny pieces of detail. Right Hemisphere is for emotion, global, and bigger picture of things.  Corpus Callosum- groups of axons that go from one hemisphere to another. 5
