    "subtitle": null,
    "abstract": "Computational models of visual working memory (VWM)\ngenerally fall into two categories: slots-based models and\nresources-based models. Slots-based models theorise that the\ncapacity of memory is defined by a finite number of items.\nEach slot can only contain one item and once an item is in\nmemory it is remembered accurately. If an item is not in\nmemory, however, there is no memory of the item at all. By\ncontrast, resources-based models claim that all items, rather\nthan just a few enter memory. However, unlike the slots model\nthey are not necessarily remembered accurately. On the\nsurface, these models appear to make distinct predictions.\nHowever, as these models have been developed and expanded\nto capture empirical data, they have begun to mimic each other.\nFurther complicating matters, Donkin, Kary, Tahir and Taylor\n(2016) proposed that observers were capable of using either\nslot- or resource-based encoding strategies. In the current\nexperiment, we aimed to test the claim that observers adapt\ntheir encoding strategies depending on the task environment by\nobserving how participants move their eyes in a VWM\nexperiment. We ran participants on a standard colour recall task\n(Zhang and Luck, 2008) while tracking their eye movements.\nAll participants were asked to remember either 3 or 6 items in\na given trial, and we manipulated whether the number of items\nwas held constant for a block of trials, or varied randomly. We\nexpected to see participants use more resource-like encoding\nwhen the number of items to remember was predictable.\nContrary to these expectations, we observed no difference\nbetween blocked and unblocked conditions. Further, the eye\ngaze data was only very weakly related to behaviour in the task.\nWe conclude that caution should be taken in interpreting eye\ngaze data in VWM experiments.",
