Subjects viewed relevant stimuli as having high information content. The storage component also indicates a higher peak amplitude for relevant stimuli, indicating that the relevant stimuli were incorporated into the short-term memory. Future plans for this study include the testing of Alzheimer's patients. Alzheimer's disease is a progressive, degenerative disease that affects over 4 million Americans. Using evoked potentials, particularly the P300 and the storage component, to study these patients will provide a better understanding of the disease and could possibly lead to an early diagnostic procedure.
Aggression is defined as any action that is intended to hurt others.
Sociologists, criminologists and psychologists alike have propounded many theories to account for this phenomenon. However, the most popular theory is the frustration-aggression model of criminal deviance. The frustration-aggression model, first developed by Dollard, Doob, Miller, Mowrer, and Sears in 1939, is a leading theory in explaining aggressive behaviors. Also, increased anger may not always lead to aggression. Thus, it is important to examine the causes of aggressive behavior as a combination of external stressors, as well as personal behavioral traits and coping mechanisms.
