Abstract

An experiment was conducted to examine the impact of negative affect on task performance of simple and complex tasks and self-evaluation ratings. Participants between the ages of 18 and 25 were recruited from psychology courses at Ripon College (N=67). Participants in the control condition first completed the Positive and Negative Affect Schedule (PANAS), and then read Velten Mood Induction (VMI) cards that were neutral in nature. They were then instructed to fill out another PANAS. The participants in the control condition reported their mood as less negative (negative affect scores) as well as more positive (differences scores) after reading the neutral statements. Participants in the negative condition were asked to complete the PANAS (for the week) and then read VMI cards that were intended to induce a negative mood. Participants were asked to complete a Sudoku puzzle (simple or complex) and then instructed to complete another PANAS (for the moment). The PANAS pre-test scores were compared to the post-test scores. Another test was performed to determine if a change in mood was due to the puzzle complexity factor. Contrary to earlier studies, the researcher did not find statistical significance (at the 5% alpha level) for any of the tests except when the pre-and post-test positive affect scores were compared. The significance of the positive PANAS scores suggests that participants' mood was less positive after the mood induction procedure. Self-evaluation scores were compared to puzzle complexity which also produced no significance. Studies involving affect can provide beneficial information about depression and the many adverse effects it can have on a person's daily life.
