Psychology 1101 9/2/08 Ethics in Psychological Research Institutional Review Board (IRB): review board at any federally funded institution responsible for reviewing all research to determine if it is ethical before it is conducted. Informed consent: research must be explained in detail before participant agrees to take part. Voluntary participation: participant must agree and must understand they can quit at any time—without penalty. Confidentiality/Anonymity: can only use data in ways specified; data should not be connected to participants’ identities.

Debriefing: after study, participant must be given most details about study. Using animals in research: o Only small % of psychological research (7-8%) o Must have good reason o Must justify any harm/pain to animal o Must keep animals in good living conditions o Controversial CHAPTER 3 The Biological Bases of Behavior Communication within the Brain Neuron: individual cells in the nervous system that receive, integrate, and transmit information. o Dendrites: receive messages from other neurons o Soma: cell body o Cell Nucleus: life support of the neuron. (nourish, remove waste products, make sure it has what it needs to survive) o Axon: a long thin fiber that transmits signals. o Information moves from dendrites through soma…works through neuron to axon, which transmits info. o Myelin Sheath: insulating material that coats the axons and speeds transmission of info. o Terminal buttons: small knobs that secrete neurotransmitters to transmit the neurons message to next neuron.

o Synapse: a junction between neurons where information is transmitted from one neuron to another. (a tiny gap/separation between neurons) How does a neuron transmit info? Action potential travels down axon to terminal buttons o Action potential: a very brief electrical charge that travels along an axon. o When action potential reaches the terminal fibers. They release neurotransmitters. Neurotransmitters: chemical messengers that are released from the terminal branches and travel across the synapse to stick to the dendrites of other neurons.
