Data from: A resource-rational theory of set size effects in human visual working memory
Encoding precision in visual working memory decreases with the number of encoded items. Here, we propose a normative theory for such set size effects: the brain minimizes a weighted sum of an error-based behavioral cost and a neural encoding cost. We construct a model from this theory and find that it predicts set size effects. Notably, these effects are mediated by probing probability, which aligns with previous empirical findings. The model accounts well for effects of both set size and probing probability on encoding precision in nine delayed-estimation experiments. Moreover, we find support for the prediction that the total amount of invested resource can vary non-monotonically with set size. Finally, we show that it is sometimes optimal to encode only a subset or even none of the relevant items in a task. Our findings raise the possibility that cognitive "limitations" arise from rational cost minimization rather than from constraints.
Different intensity exercise and verbal spatial working memory Data
<p><span><b><span>Background:</span></b> The inconsistent results of the studies on whether acute exercise can improve working memory and the small effect sizes of meta-analysis indicate that there may be some moderating variables affecting the intensity of the relationship between acute exercise and working memory. This research examined the effects of different intensity acute exercise on the two types of working memory.</span></p> <p><span><b><span>Methods: </span></b>Seventy-eight low active college students aged 18 to 22 years were selected and randomly assigned to four groups. The low-intensity group (n=19), moderate-intensity group (n=19) and high-intensity group (n=19) completed 30-min cycle ergometer exercise bouts separately at the intensity of 40%, 60% and 80% of Vo2max, while the control group (n=21) read for 30-min. The delayed match-to-sample test was used to test verbal and spatial working memory after the intervention.</span></p> <p><span><b><span>Results: </span></b>On response time and accuracy, the main effects of acute exercise intensity and working memory type were significant (<i><span>p</span></i><0.05), and the interaction effect of acute exercise intensity and working memory type was significant (<i><span>p</span></i><0.05).</span></p> <p><span><b><span>Conclusions: </span></b>Acute exercise can improve verbal and spatial working memory, while the moderate intensity of acute exercise has the best effect. Compared with verbal working memory, the effect of acute exercise on spatial working memory is greater.</span></p> <p> </p>
Data from: Increased dopamine release after working-memory updating training: neurochemical correlates of transfer
Previous work demonstrates that working-memory (WM) updating training results in improved performance on a letter-memory criterion task, transfers to an untrained n-back task, and increases striatal dopamine (DA) activity during the criterion task. Here, we sought to replicate and extend these findings by also examining neurochemical correlates of transfer. Four positron emission tomography (PET) scans using the radioligand raclopride were performed. Two of these assessed DAD2 binding (letter memory; n-back) before 5 weeks of updating training, and the same two scans were performed post training. Key findings were (a) pronounced training-related behavioral gains in the letter-memory criterion task, (b) altered striatal DAD2 binding potential after training during letter-memory performance, suggesting training-induced increases in DA release, and (c) increased striatal DA activity also during the n-back transfer task after the intervention, but no concomitant behavioral transfer. The fact that the training-related DA alterations during the transfer task were not accompanied by behavioral transfer suggests that increased DA release may be a necessary, but not sufficient, condition for behavioral transfer to occur.
