We conducted a preregistered multilaboratory project ( k = 36; N = 3,531) to assess the size and robustness of ego-depletion effects using a novel replication method, termed the paradigmatic replication approach. Each laboratory implemented one of two procedures that was intended to manipulate self-control and tested performance on a subsequent measure of self-control. Confirmatory tests found a nonsignificant result ( d = 0.06). Confirmatory Bayesian meta-analyses using an informed-prior hypothesis (δ = 0.30, SD = 0.15) found that the data were 4 times more likely under the null than the alternative hypothesis. Hence, preregistered analyses did not find evidence for a depletion effect. Exploratory analyses on the full sample (i.e., ignoring exclusion criteria) found a statistically significant effect ( d = 0.08); Bayesian analyses showed that the data were about equally likely under the null and informed-prior hypotheses. Exploratory moderator tests suggested that the depletion effect was larger for participants who reported more fatigue but was not moderated by trait self-control, willpower beliefs, or action orientation.

Food waste is considered to be one of the biggest issues affecting individuals around the globe. The COVID-19 pandemic, with the consequent lockdown processes, has recently triggered individuals to stockpile foodstuffs. Recent data shows, however, that individuals have not consumed a good proportion of the stockpiled food, resulting in increasing amounts of products ending up wasted. Using a cross-national survey conducted in the United States and India, we investigate how individuals' levels of need for cognitive closure (NFC) relate to food stockpiling and waste during the COVID-19 pandemic. Through a sequential mediation model, we show how individuals high in NFC did not perceive to have enough food at home, ending up buying more food than usual and, eventually, wasting more. Individuals' gender and country of residence moderate such phenomenon, with the effect being more pronounced among Indian (rather than American) women. We discuss how gender roles in different countries can correlate with the stockpiling and food waste processes. We conclude the manuscript by suggesting how public communication and policy making could develop targeted programs to mitigate such issues.

This research used open source information to investigate the motivational backgrounds of 219 suicide attackers from various regions of the world. We inquired as to whether the attackers exhibited evidence for significance quest as a motive for their actions, and whether the eradication of significance loss and/or the aspiration for significance gain systematically differed according to attackers' demographics. It was found that the specific nature of the significance quest motive varied in accordance with attackers' gender, age, and education. Whereas Arab-Palestinians, males, younger attackers, and more educated attackers seem to have been motivated primarily by the possibility of significance gain, women, older attackers, those with little education, and those hailing from other regions seem to have been motivated primarily by the eradication of significance loss. Analyses also suggested that the stronger an attacker's significance quest motive, the greater the effectiveness of their attack, as measured by the number of casualties. Methodological limitations of the present study were discussed, and the possible directions for further research were indicated.

This is the first time that EEG has been applied to children with sensorineural hearing loss with the purpose of studying the cognitive load during effortful listening. Significantly higher parietal alpha power levels in two of three noisy conditions, compared to the quiet condition, are consistent with increased cognitive load. Specifically, considering the time window of the analysis (pre-stimulus), parietal alpha power levels may be a measure of cognitive functions such as sustained attention and selective inhibition. In this respect, the significantly lower parietal alpha power levels in the most challenging listening condition (i.e. noise to the better ear) may be attributed to loss of attention and to the subsequent fatigue and "withdrawal" from the task at hand.
