    <jats:title>Abstract</jats:title><jats:p>Attentional mechanisms in perception can operate over locations, features, or objects. However, people direct attention not only towards information in the external world, but also to information maintained in working memory. To what extent do perception and memory draw on similar selection properties? Here we examined whether principles of object-based attention can also hold true in visual working memory. Experiment 1 examined whether object structure guides selection independently of spatial distance. In a memory updating task, participants encoded two rectangular bars with colored ends before updating two colors during maintenance. Memory updates were faster for two equidistant colors on the same object than on different objects. Experiment 2 examined whether selection of a single object feature spreads to other features within the same object. Participants memorized two sequentially presented Gabors, and a retro-cue indicated which object and feature dimension (color or orientation) would be most relevant to the memory test. We found stronger effects of object selection than feature selection: accuracy was higher for the uncued feature in the same object than the cued feature in the other object. Together these findings demonstrate effects of object-based attention on visual working memory, at least when object-based representations are encouraged, and suggest shared attentional mechanisms across perception and memory.</jats:p>

  • Developing a Method to Measure Dynamic Visual Working Memory

    2022   David Alais

     View Summary

    In this project, we aimed to develop an efficient method tomeasure dynamic visual working memory. Extant visual working memory measureswork only with static images, which participants commit to memory before beingasked a question about the stimulus, a process with two major disadvantages. Therestriction to static images is not reflective of how visual working memoryworks in real life, where most things we commit to working memory are dynamic,moving objects. Each visual working memory trial can only produce a very smallamount of data, so experiments would have to include hundreds or thousands oftrials to reliably measure visual working memory. &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; In thisproject, we created a dynamic working memory involve dots moving around the screenin a semi-predictable manner. The participant then retraced a dot’s movementpath using a touchscreen to minimise response error. The actual movement pathand response are compared using an exhaustive point-by-point comparison processthat produces the average under a best-case scenario. Through this process, thisexperiment can collect hundreds of data points with a single trial. Furtherexperimentation demonstrates that this new process is both reliable and powerful.

  • Raising the Efficiency of Attention through Complex Constructs

    2021  

     View Summary

    Attention is the ability to filter out irrelevant noise andfocus only on what is currently important. It is typically studied in thecontext of attending to perception, i.e., directly externally towards theworld. However, attention can also be directed internally, towards objects heldin visual working memory. This project aimed to investigate this internally-directedattention, and specifically, how this process compared to the typicalexternally-directed attention. We hypothesised that differences between visualand memory representations in the brain would inevitable cause differenced inhow attention would interact with the two. Previous research on external attentionsuggests that only a single feature can be attended to at a time in perception,but this attended feature can be switched at will, rapidly and effortlessly. Thisresearch project found that when internally attending to visual working memory,attention can then be drawn only to a single, primary feature. Accessing otherfeatures first required going through the primary feature. In other words, thisprimary feature acts as an attentional index through which the objects inmemory can be subsequently accessed. Furthermore, the choice of the primaryfeature appears to be under volitional control, likely selected at the time ofmemory encoding.
