Abstract:Visual working memory (VWM), as the functional unit to temporarily store visual information, has been mainly viewed from the perspectives of two opposing classes of models. Firstly, the integrated object perspective, which supports a discrete capacity limit on the object level, and secondly, the feature binding models according to which VWM resources are more flexible and continuous on the feature dimension level. Recent activity in the field challenged the validity of memory precision measures of feature-based approaches. This motivated the current study to conduct the main VWM task with individualized sets of stimuli, which were identified in a pre-experimental phase. Results of the main VWM task confirm the significant impact of the number of presented stimuli and the attentional instructions on memory precision, which both argue against the integrated object perspective. More so, the results fit a conceptualization of VWM with flexible feature resources that tend to be reallocated to the more difficult memory subjects. The current findings show the relevance of attention and individual differences in perception within the research of VWM. This requires future research to differentiate human VWM performance and measures for VWM resource limits according to these qualitative dimensions.
