What is psychobiology?
- Focus on the brain and behavior
- One of the many disciplines within the broad field of neuroscience
Psychobiology: the scientific study of the biology of behavior
- The Organization of Behavior by D.O. Hebb
o ke fator i pshoiolog’s deelopet ito a ajor eurosietifi disiplie
o proposed that psychological phenomena might be produced by brain activity
o helped discredit the notion that psychological functions were too complex to be derived from
physiological activities
o did experiments on humans and non-humans
▪ this eclectic approach left a precedent for the present
psychobiology is an integrative discipline
- meaning that it draws together knowledge form the other neuroscientific disciplines

psychobiological research has 3 dimensions
1. subjects
o human
▪ pros: can follow instructions, cheaper to work with, can report their experiments, have a
human brain, since this field is about the human its great to actually experiment with
humans
▪ os: at aipulate so that’s h a lot of eperiets are doe o o-humans
o non human
▪ pros: saller rais so its ore lea to eperiet ith the, a ohuas hae
similar brain structures to humans which helps with the comparative approach which is
when you make comparisons with other species, fewer ethical restrictions (can do
experiments on their brains but not on human brains)
2. methods
o experiments: help to determine the cause and effect relationships
▪ between and within experiments and independent and dependent variables
▪ between- and withint-subjects designs
▪ between-subjects
• cons: not as controlled
? DEFINE BETWEEN-AND WITHIN-SUBJECTS
▪ within-subjects: better
• you are your own control
• ex: make entire group do cardio then take results than make the entire group do
weight-lifting then take results
• good because everyone has done both tests
• more preferred
▪ independent variables: what you change
▪ dependent variables: what you measure
▪ preferred over any other type of research
▪ sometimes its not possible to control everything because of confounded variables
• these can be difficult to eliminate
• can make experiments difficult to interpret; hard to tell how much of the effect
of the confounding varbiable had on the dependent variable
o nonexperiments
▪ when you cant control variables
▪ quasiexperimental studies:
• not considered real experiments bc potential confounding variables have not
been controlled
• ex: cant randomly assign people to be male/female
• ex: do a study on alcoholics and non-alcoholics; cant randomly assing people to
be alcoholics → have to pick from existing populations (people who are already
alcoholic or not) so theres no true IV bc no manipulation
▪ case studies:
• used a lot in different fields, not necessarily psychobiology
• focus on a single case/subject
• can go more in-depth usually
• good source of testable hypotheses
• cannot diagnose causality

Document Summary
Jared wong jaredw@ucla. edu office: franz 8586 tues: 12:20 -1:20 by appt. No office hours week 0 and 1. Midterm and final: non cumulative, 50 question multiple choice tests. 2 opportunities for extra credit for a whole percentage point. 11/7 (tues) midterm (material from 9/28 10/31) One of the many disciplines within the broad field of neuroscience. Psychobiology: the scientific study of the biology of behavior. Physiological psychology: studies the neural mechanisms of behavior, what cells are working together, usually done on laboratory animals (rats) bc a lot of direct manipulations are involved, pure research. Psychopharmacology: done on both humans and animals focuses on the manipulation of neural activity, not with surgery but with drugs. Done more on humans, as opposed to physiological psychology (done more on lab rats) Mri machines help see which parts of the brain light up when told specific tasks to do. Compare diff species to understand evolution, genetics, and adaptiveness of behavior.
