The dark side of dialog

We agree that the self is constructed through a collaborative dialog. But hostile interlocutors could use various cognitive techniques to hijack the dialog, resulting in beliefs, values, and even selves that are out of line with reality. The implications of this problem are dire, but we suggest that increased metacognitive awareness could help guide this process to a truthful conclusion

The Dunning-Kruger effect in Emirati college students: Evidence for Generalizability across cultures

© 2020 AAC. Past research reports higher levels of overconfidence for low performers compared to more proficient performers. This finding has been attributed to low performers\u27 lack of insight into their cognitive processes, and it is referred as the Dunning-Kruger effect. This effect has been replicated across various tasks and domains. To date, however, there have been very limited explorations of the Dunning-Kruger effect in individuals from Non-Western, collectivist countries, where self-enhancing biases might be less prevalent. The aim of this study is to explore whether the Dunning-Kruger effect is also demonstrated among Arab, college students in the United Arab Emirates. Emirati, female college students completed a matrix reasoning task and subsequently assessed their own performance on it by estimating their raw score. The results replicated the Dunning-Kruger effect. Participants scoring in the lowest quartile significantly overestimated their performance and demonstrated levels of overconfidence significantly higher than that of more proficient peers. This study extends our understanding of overconfidence and the Dunning-Kruger effect to the Arab world. The results are discussed with reference to proposed underlying mechanisms

Metacognition is Prior

We agree with Carruthers that evidence for metacognition in species lacking mindreading provides dramatic evidence in favor of the metacognition-is-prior account and against the mindreading-is-prior account. We discuss this existing evidence and explain why an evolutionary perspective favors the former account and poses serious problems for the latter account

Animal Metacognition: Problems and Prospects

Researchers have begun to evaluate whether nonhuman animals share humans’ capacity for metacognitive monitoring and self-regulation. Using perception, memory, numerical, and foraging paradigms, they have tested apes, capuchins, a dolphin, macaques, pigeons, and rats. However, recent theoretical and formal-modeling work has confirmed that some paradigms allow the criticism that low-level associative mechanisms could create the appearance of uncertainty monitoring in animals. This possibility has become a central issue as researchers reflect on existing phenomena and pause to evaluate the area’s current status. The present authors discuss the associative question and offer our evaluation of the field. Associative mechanisms explain poorly some of the area’s important results. The next phase of research in this area should consolidate the gains achieved by those results and work toward a theoretical understanding of the cognitive and decisional (not associative) capacities that animals show in some of the referent experiments

Contextual cueing is not flexible

Target detection is faster when search displays repeat, but properties of the memory representations that give rise to this contextual cueing effect remain uncertain. We adapted the contextual cueing task using an ABA design and recorded the eye movements of healthy young adults to determine whether the memory representations are flexible. Targets moved to a new location during the B phase and then returned to their original locations (second A phase). Contextual cueing effects in the first A phase were reinstated immediately in the second A phase, and response time costs eventually gave way to a repeated search advantage in the B phase, suggesting that two target-context associations were learned. However, this apparent flexibility disappeared when eye tracking data were used to subdivide repeated displays based on B-phase viewing of the original target quadrant. Therefore, memory representations acquired in the contextual cueing task resist change and are not flexible

Metacognitive monitoring in test-taking situations: A cross-cultural comparison of college students

© 2020, Eskisehir Osmangazi University. In this study, we examined monitoring accuracy during in class-exams for Emirati, American and Cypriot college students. In experiment 1, 120 students made local, confidence-ratings for each multiple-choice question in a psychology exam and also estimated their performance at the end of the exam. In experiment 2, to investigate the effect of practice in monitoring accuracy, 69 students made confidence judgments in two consecutive exams. In Experiment 3, to evaluate whether rating one\u27s confidence aids exam performance, 172 students completed the exam either with or without providing confidence judgments. In all three cultures, confidence judgments were accurate indicators of performance, but there were significant cross-cultural differences that probably arose from regional educational practices. Additionally, global judgments were subjected to bias. Whereas American students overestimated their performance, Emiratis underestimated it. Practice alone with confidence judgments did little to improve monitoring accuracy. But there was a significant benefit for students who rated their confidence compared to those that did not. The results are discussed in light of the literature on metacognitive accuracy

Heterogeneity in Perceptual Category Learning by High Functioning Children with Autism Spectrum Disorder

Previous research suggests that high functioning children with Autism Spectrum Disorder (ASD) sometimes have problems learning categories, but often appear to perform normally in categorization tasks. The deficits that individuals with ASD show when learning categories have been attributed to executive dysfunction, general deficits in implicit learning, atypical cognitive strategies, or abnormal perceptual biases and abilities. Several of these psychological explanations for category learning deficits have been associated with neural abnormalities such as cortical underconnectivity. The present study evaluated how well existing neurally-based theories account for atypical perceptual category learning shown by high functioning children with ASD across multiple category learning tasks involving novel, abstract shapes. Consistent with earlier results, children’s performances revealed two distinct patterns of learning and generalization associated with ASD: one was indistinguishable from performance in typically developing children; the other revealed dramatic impairments. These two patterns were evident regardless of training regimen or stimulus set. Surprisingly, some children with ASD showed both patterns. Simulations of perceptual category learning could account for the two observed patterns in terms of differences in neural plasticity. However, no current psychological or neural theory adequately explains why a child with ASD might show such large fluctuations in category learning ability across training conditions or stimulus sets

Brazilian Flora 2020: Leveraging the power of a collaborative scientific network

International audienceThe shortage of reliable primary taxonomic data limits the description of biological taxa and the understanding of biodiversity patterns and processes, complicating biogeographical, ecological, and evolutionary studies. This deficit creates a significant taxonomic impediment to biodiversity research and conservation planning. The taxonomic impediment and the biodiversity crisis are widely recognized, highlighting the urgent need for reliable taxonomic data. Over the past decade, numerous countries worldwide have devoted considerable effort to Target 1 of the Global Strategy for Plant Conservation (GSPC), which called for the preparation of a working list of all known plant species by 2010 and an online world Flora by 2020. Brazil is a megadiverse country, home to more of the world's known plant species than any other country. Despite that, Flora Brasiliensis, concluded in 1906, was the last comprehensive treatment of the Brazilian flora. The lack of accurate estimates of the number of species of algae, fungi, and plants occurring in Brazil contributes to the prevailing taxonomic impediment and delays progress towards the GSPC targets. Over the past 12 years, a legion of taxonomists motivated to meet Target 1 of the GSPC, worked together to gather and integrate knowledge on the algal, plant, and fungal diversity of Brazil. Overall, a team of about 980 taxonomists joined efforts in a highly collaborative project that used cybertaxonomy to prepare an updated Flora of Brazil, showing the power of scientific collaboration to reach ambitious goals. This paper presents an overview of the Brazilian Flora 2020 and provides taxonomic and spatial updates on the algae, fungi, and plants found in one of the world's most biodiverse countries. We further identify collection gaps and summarize future goals that extend beyond 2020. Our results show that Brazil is home to 46,975 native species of algae, fungi, and plants, of which 19,669 are endemic to the country. The data compiled to date suggests that the Atlantic Rainforest might be the most diverse Brazilian domain for all plant groups except gymnosperms, which are most diverse in the Amazon. However, scientific knowledge of Brazilian diversity is still unequally distributed, with the Atlantic Rainforest and the Cerrado being the most intensively sampled and studied biomes in the country. In times of “scientific reductionism”, with botanical and mycological sciences suffering pervasive depreciation in recent decades, the first online Flora of Brazil 2020 significantly enhanced the quality and quantity of taxonomic data available for algae, fungi, and plants from Brazil. This project also made all the information freely available online, providing a firm foundation for future research and for the management, conservation, and sustainable use of the Brazilian funga and flora
