Retention and productivity in industrial search and scan tasks

Camilo Aguilera, University of Texas at El Paso


An experiment was developed in order to study the interaction between individual factors (gender and mood) and the retention ability in search and scan activities. 54 subjects between 18 and 30 years old participated in a computer-based memory test from the North of Mexico area. A full factorial design was used to analyze the variables. Two factors, one with two levels (gender: male and female), and the second factor with three levels (mood: positive, neutral, and negative) were used in the analysis. The output was measured as the amount of characters memorized in a string of random alphanumeric characters. Data gathered showed that gender was not a significant factor (P=0.09), yet mood was a significant factor (P<0.005). Based on Tukey test, each level in the mood factor is significantly different among them. Positive mood showed the highest value, followed by neutral, and negative mood (sad, angry, depressed) showed the lowest amount of characters memorized.
