Working memory affine technological support functions improve decision performance

While working memory limits constrain the complexity of manageable tasks, technological devices offer vast information processing capacity and thus the potential to improve individual information processing capabilities and task performance. We explored the effects of providing individuals with intuitive, working memory affine information structuring support functionalities on a multi-touch table on decision performance. In the employed hidden profile personnel selection task (Stasser & Titus, 1985) support should enable participants to offload cognitive processing, thus improving information processing and decision quality. In Experiment 1 (N = 76) we compared decision performance without vs. with technological support (self-directed and automatic structuring functionalities). Support led to higher chances for a correct decision, more appropriate candidate suitability ratings and better information recognition compared to no support. In Experiment 2 (N = 81) we focused on self-directed structuring, comparing conditions with vs. without detailed usage instructions for self-structuring functionalities. While there was no difference with regard to decision quality, participants displayed more appropriate candidate suitability ratings and better recognition performance with detailed usage instructions than without. Our findings indicate that offering working memory affine technological support functions to ameliorate cognitive limitations is effective and highlight that detailed instructions might amplify this potential.
