Three experiments measured the efficiency of monitoring complex scenes composed of changing objects, or events. All events lasted about 4 s, but in a given block of trials, could be of a single type (single task) or of multiple types (multitask, with a total of four event types). Overall accuracy of detecting target events amid distractors was high...

Do color relations such as similarity or harmony influence the ease with which colored patterns can be perceived and held in mind? We tested the influence of a relation supported in research on color harmony--similarity of hue--on the capacity of visual short-term memory (VSTM) for colors in patterns. Palettes of 4 similar-hue colors were rated as...

Previous research measuring visual short-term memory (VSTM) suggests that the capacity for representing the layout of objects is fairly high. In four experiments, we further explored the capacity of VSTM for layout of objects, using the change detection method. In Experiment 1, participants retained most of the elements in displays of 4 to 8 elemen...

Three experiments examined the time course of layout priming with photographic scenes varying in complexity (number of objects). Primes were presented for varying durations (800-50 ms) before a target scene with 2 spatial probes; observers indicated whether the left or right probe was closer to viewpoint. Reaction time was the main measure. Scene p...
Conference Paper
In surveillance situations, computer vision systems are often deployed to help humans perform their tasks more effectively. In a typical installation human observers are required to simultaneously monitor a number of video signals. Psychophysical research indicates that there are severe limitations in the ability of humans to monitor simultaneous s...

... Expectations and predictions can voluntarily direct attention towards a particular event that is considered to be important for the individual. In real-world scenes, however, top-down task dependent information also biases the sensory selection process [70]. ...
... The information saved in the surveillance system is accessed and processed on a needed basis. Processing the stored data in a surveillance system by the human being in real-time consumes more time [38]. So, finding unusual human activities like falls automatically in the surveillance video is the solution to this problem [11,17,35,47]. ...
... In the visual domain, studies conducted so far converge toward a facilitative effect of between-item similarity on WM performance. Increased performance has been observed following the manipulation of color similarity, both in simultaneous and sequential presentations (Lin & Luck, 2009;Quinlan & Cohen, 2012;Sanocki & Sulman, 2011). This advantage for similar colors is all the more present that the similar colors are spatially close to each other during encoding (Peterson & Berryhill, 2013). ...
... A growing body of work points to an important role for knowledge of statistical regularities in VWM, and suggests that use of statistical regularities allows for more efficient memory (Bae, Olkkonen, Allred, & Flombaum, 2015;Brady, Konkle, & Alvarez, 2009;Brady & Tenenbaum, 2013;Corbett, 2016;Huttenlocher, Hedges, & Vevea, 2000;Orhan & Jacobs, 2013;Sanocki, Sellers, Mittelstadt, & Sulman, 2010;Sims et al., 2012;Swan, Collins, & Wyble, 2016;Victor & Conte, 2004). For example, and Corbett (2016) showed that subjects' memories for items in a display are biased toward items' summary statistics, meaning statistical regularities averaged over multiple 1 Here, 'bit allocation' specifically refers to changes in the pattern of memory errors resulting from adapting VWM to the current task. ...
... Trial timing was chosen to match previous spatial congruency bias paradigms (Golomb et al, 2014). The 500ms presentation time should enable sufficient time to process the depth cue and accumulate accurate information for depth perception from binocular disparity 1 (Adam et al., 1993;Sanocki & Sulman, 2009;Uttal, Davis, & Welke, 1994). Masks were included to ensure visual afterimages were not used to help with the same/different location task. ...
