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
