Orderly, systematic procedures that researchers follow as they identify a research problem.
design a study to investigate the problem
collect and analyze data
To seek new knowledge and to explore; advance general scientific understanding.
To Specifically to solve practical problems and improve quality of life.
Factor or condition in experiment that is delibrately manipulated in order to determine whether it causes change in another behavior or condition.
Factor or condition that is measured at the end of an experience and is persumed to vary as result of manipulations of the Independant Variable.
Specialized cells that conduct impulses through the nervous system and contain three major parts:
Chemical substance that is released into the synaptic cleft from the Axon terminal from sending Neuron, Cross a synapse, bind to appropriate receptor sites on dendrites or cell body of a recieving neuron, Influencing the cell to fire/not fire.
Central Nervous System
Comprising of the brain and spinal cord.
Peripheral Nervous System
The nerves connecting the CNS to the rest of the body.
Part of brainstem that controls heart beat, blodd preesure, breathing, coughing, and swallowing.
Small brain structure that regulates hunger, thirst, sexual behavior, internal body temp, and other body functions including emotional behaviors
Structures in forebrain, including Amydala and Hippocampus, that are involves in emotion expression, memory, and modivation.
Structue in Limbic Sys. that plays role in storing new memories, the response to new or unexpected stimuli/ navigational ability.
Everything which we are aware at a given time, Our thoughts, feelings, sensations, and perceptions of the external enviroment.
Function of sleep is to restore body and mind.
Theory that sleep evolved to keep humans out of harm's way during the night; also know as Evolutionary Theory.
Non- Raped Eye Movement, consists of four sleep stages and is characterized by slow, regular respiration and heart rate, little body movement , and blood pressure and brain activity that are at their 24 hour low points.
Rapid Eye Movement, Paralysis of large muscles, fast and irregular heart and respiration rates, increased brain wave activity and vivid dreams
Period of sleep lasting 90 minutes and including one or more stages of NREM sleep followed by REM Sleep.
Stage 1- wake to sleeping; irregular waves
Stage 2- lighter to deeper sleep; (sleep spindles) waves with alternating periods of calm and flashes of intense activity appear
Stage 3- deeper sleep; (slow-wave sleep) begins when EEG shoes 20% of brain waves are Delta
Stage 4- deepest sleep; Stage four sleep begins when 50% of waves are delta waves; about 40 minutes later begin to disappear.
Rod-shaped structures in the nuclei of body cells, which contain all the genes and carry all the genetic info to make a human being.
