This may be a long-shot, but I'm looking for a paper that I vaguely remember reading a few years ago. Unfortunately I can't remember many details about the paper or its content, and thus my multiple attempts at keyword searches have failed. I'm posting this question in the hope that someone recognises the few details I do remember.The paper presented more than one experiment, but the one I'm trying to recall involved a colour wheel/pie displayed in the centre of the screen. The slices of the pie were each a different colour and the colours would change a few times throughout each trial. There were only a small number of slices/colours. The observer's task was to count the number of times the colours changed. While doing this the observer also had to perform another task, for which the stimuli were shown on the rest of the display, in peripheral vision. I can't remember what the other task was, though it may have been a multiple object tracking task or a visual search task. The paper may have been about the effect of attentional load on working memory, though I'm not sure about that.
What is the study with the dual-task experiment that involved a colour-wheel change detection task?

I eventually tracked it down by going through every single result of every possible relevant search I could think of.Makovski, T., & Jiang, Y. V. (2009). The Role of Visual Working Memory in Attentive Tracking of Unique Objects. Journal of Experimental Psychology: Human Perception and Performance, 35(6), 1687-1697.It's available for free on the NIH site. It was experiment 4. Figure 5 gives an illustration of the stimuli.
