Bio Psych Terms Chapter 1 Neurons – cells that receive and transmit electrochemical signals Neuroscience –the scientific study of the nervous system Evolutionary perspective – environmental pressures that likely led to the evolution of our brains and behavior often leads to important biopsychological insights. Biopsychology – the scientific study of the biology of behavior. Comparative approach – the study of biological processes by comparing different species. Between subjects design – a different group of subjects is tested under each condition. Within-subjects design – test the same group of subjects under each condition Independent variable – the difference between the condition Dependant variable – the variable that is measured by the experimenter to assess the effect of the independent variable. Confounded variable – The unintended differences in the experiment that are not the IV. Coolidge effect – the fact that a copulating male who becomes incapable of continuing to copulate with one sex partner can often recommence copulating with a new sex partner. Lordosis – (the arched-back, rump-up, tail diverted posture of the female rodent sexual receptivity. Quasiexperimental studies – studies of groups of subjects who have been exposed to the conditions of interests in the real world. These studies have the appearance of experiments, but they are not true experiments because potential confounded variables have been controlled. Case studies – studies that focus on a single case or subject.

Generalizability – the degree to which their results can be applied to other cases. Pure research – research motivated primarily by the curiosity of the researcher it is done purely for the purpose of acquiring knowledge. Applied research – research intended to bring about some direct benefit to humankind. 6 divisions of biopsychology: Physiological psychology – the division of biopsychology that studies the neural mechanisms of behavior through direct manipulation of the brain in controlled experiments-surgical, and electrical methods of the brain manipulation are most common. Pyschopharmacology – it focuses on the manipulation of neural activity and behavior with drugs. Similar to physiological psychology, but deals with drugs and manipulation of the brain. Applied research. Neuropsychology – the study of the psychological effects of brain damage in human patients. Obviously human subjects cannot ethically be exposed to experiments. Deals with patients who already have sustained brain damage. Psychophysiology – the division of bio-psych that studies the relation between physiological activity and psychological processes in human subjects. Non-invasive research, records from the surface of the body. Uses EEG scans. Focuses on the psychological aspects of attention, emotion, and information processing. Cognitive neuroscience – the youngest division of biopsychology, but
