| dc.description.abstract | When performing everyday tasks, we make use of our visual working memory (VWM) to
temporarily store the information we see. In this study, we have designed the TCC-AT model
which can predict naturalistic behaviour where VWM is used with only two parameters: memory
strength (how well something is remembered) and action threshold (is the confidence in memory
high enough to commit). We also designed and performed an experiment where people used
VWM to remember colours and were tasked with reporting on those colours. For every memory
task performed participants had to decide if they were confident enough in their memory to
commit, either losing or gaining points depending on how well they remembered the colours. By
making groups of participants remember a different number of objects at the same time, and
making the strictness of the scoring different, the behaviour reflected different memory strengths
and action thresholds in the TCC-AT model. The results showed that the model was consistent
in predicting memory strength, but not in predicting action threshold. Multiple factors in the
model and experiment were identified which could cause the problems in predicting action
thresholds. | |
