“…Such a finding is in line with prior studies, which have reported a loss in visual memory accuracy over time (e.g. Hesse & Franz, 2010;McKeown et al, 2014;Morey & Bieler, 2013;Poom, 2012;Ricker & Cowan, 2010Salmela et al, 2010). Nonetheless, the overall impact of the retention interval remains uncertain and future studies may benefit from employing a range of delaysstronger effects of time with Fribble stimuli have been found after 10 s gaps (Mercer, 2014).…”

Retroactive interference occurs when new information disrupts the retention of an existing representation, but its effects on visual short-term memory remain poorly understood. The present study examined three factors predicted to influence domain-specific retroactive interference, including the type of distractor, its temporal position, and the length of the retention interval. Participants compared target and test objects over a brief interval that either was unfilled or contained a similar or dissimilar distractor occurring 200 ms or 1.5 s after the target offset. Retention was influenced by the temporal position of the distractor and its relationship with the to-be-remembered target. Specifically, retroactive interference was only observed following the presentation of a dissimilar distractor that occurred 1.5 s after the target. These results suggest that novel distractors may be particularly interfering.

“…Using PLDs as stimuli of interest, a very recent study elegantly explored the WM storage of gender and gait direction information from BM stimuli. Poom (2012) found that direction information can be well kept for 9 s, yet gender information decayed by that time. To our knowledge, the current study is the second study to explore the WM mechanisms for meaningful BM stimuli.…”

Working memory (WM) mechanisms for verbal, spatial, and object information have been extensively examined, yet those for kinetic information are less known. The current study explored the WM capacity and architecture of kinetic information by examining the maintenance of biological motion (BM) stimuli in WM. Human BM is the most salient and biologically significant kinetic information encountered in everyday life. We isolated motion signals of human BM from non-BM sources by using point-light displays as to-be-memorized BM. During a change detection task, we found that, at most, 3 to 4 BM stimuli could be retained in WM (Experiment 1). Next, we found that extra colors, spatial locations, or shapes remembered concurrently with BM stimuli (Experiments 2, 3, and 4, respectively), did not affect BM memory considerably. However, BM memory was affected by a concurrent memory task of non-BM movements (Experiment 5). These results support the hypothesis that an independent storage buffer of WM exists for kinetic information, which can hold up to 3 to 4 motion units.

“…By using point-light displays as stimuli, we recently demonstrated that working memory can hold up to three or four BM stimuli (Shen et al, 2014). Current research has begun to investigate the mechanisms of maintaining BM represen tations in working memory, such as the frame of reference for retaining a BM stimulus in working memory (Wood, 2010), re hearsal mechanisms for BM in working memory (Gao, Bentin, & Shen, 2014), and retaining gait and gender information of BM in working memory (Poom, 2012).…”

Working memory mechanisms for binding have been examined extensively in the last decade, yet few studies have explored bindings relating to human biological motion (BM). Human BM is the most salient and biologically significant kinetic information encountered in everyday life and is stored independently from other visual features (e.g., colors). The current study explored 3 critical issues of BM-related binding in working memory: (a) how many BM binding units can be retained in working memory, (b) whether involuntarily object-based binding occurs during BM binding, and (c) whether the maintenance of BM bindings in working memory requires attention above and beyond that needed to maintain the constituent dimensions. We isolated motion signals of human BM from non-BM sources by using point-light displays as to-be-memorized BM and presented the participants colored BM in a change detection task. We found that working memory capacity for BM-color bindings is rather low; only 1 or 2 BM-color bindings could be retained in working memory regardless of the presentation manners (Experiments 1-3). Furthermore, no object-based encoding took place for colored BM stimuli regardless of the processed dimensions (Experiments 4 and 5). Central executive attention contributes to the maintenance of BM-color bindings, yet maintaining BM bindings in working memory did not require more central attention than did maintaining the constituent dimensions in working memory (Experiment 6). Overall, these results suggest that keeping BM bindings in working memory is a fairly resource-demanding process, yet central executive attention does not play a special role in this cross-module binding.
