Document Summary
Presumes brain processes information like a computer serial and discrete function in that all processes are sprite from one another. Sensory info attained from external sources is detected and transformed into neurological signals. Neurological signals mapped onto a meaningful event (senses make it conscious to you: pattern recognition: Extracting patterns from environment to be used in latter stages of info processing. Can be a natural or trained phenomenon: training can optimize performance in temporally demanding sports and jobs. Dependent variable: variable that is measured: change in dependent variable is assumed to be a result of change in independent variable. Independent variable: (have 2 levels or more) manipulated variable by experimenter: observe effects of independent variable on dependent variable. Acoustic stimuli have shorter reaction times than visual stimuli. 2 groups in a study means that is one independent variable time of assessment (2 levels) 2 independent variables with 2 levels= 2x2 experiment dependent variable: reaction time.
