Abstract During this investigation‚ we will replicate the study by Stroop (1935) that resulted that our serial verbal reactions are affected by interference. In the investigation‚ 10 participants will be gathered‚ then will be given a paper that contains a list of color names that are written in colors that are congruent of the name of the color‚ they are to read the words out loud. A second paper will be given to them after the first. The second paper will contain a list of words that are again

Schrödinger’s equation by numerical integration Abstract The aim of this program is to solve Schrödinger’s equation via a numerical method and to compare our results with the analytical result. The harmonic oscillator potential was taken as the potential in the equation. This was used because the solutions to this one dimensional system are well known‚ and an analytic solution is relatively easy to program. The idea is that once we have verified that our numerical approach works for this

The Stroop test‚ on the other hand‚ is a neuropsychological test that measures a person’s attention span in response to both visual and verbal stimulation in order to investigate individual executive functioning and potential cognitive deficits as they relate to conflict resolution and behaviors. Stroop testing is an efficient assessment for identifying appropriate and inappropriate behaviors in a conflict since it evaluates participants on levels of cognitive functioning.
