Mireille Babineau, Anne Christophe (2022). Preverbal infants' sensitivity to grammatical dependencies. Infancy. doi: 10.1111/infa.12466. Epub ahead of print. PMID: 35353438.

Résumé
During their first months of life, infants can already distinguish function words (e.g., pronouns and determiners) from content words (e.g., verbs and nouns). Little research has explored preverbal infants' sensitivity to the relationships between these word categories. This preregistered study examines whether French-learning 8- and 11-month-olds track the grammatical dependencies between determiners and nouns as well as pronouns and verbs. Using the Visual Fixation Procedure, infants were presented with lists containing either grammatical (e.g., tu manges "you eat", des biberons "some bottles") or ungrammatical (e.g., des manges "some eat", tu biberons "you bottle") phrases. In Experiment 1 (N = 59), the lists involved common nouns and verbs, while in Experiment 2 (N = 28), only common verbs were used. Eleven-month-olds showed a clear preference for correct over incorrect co-occurrences in both experiments, while 8-month-olds showed a trend in the same direction. These results suggest that before their first birthday, infants' storage and access of words and word sequences are sufficiently sophisticated to include the means to track categorical dependencies. This early sensitivity to co-occurrence patterns may be greatly beneficial for constraining lexical access and later on for learning novel words' syntactic and semantic properties.

Bordonaba Plou, David, Fernández Castro, Víctor and Torices, José Ramón (2022). The Political Turn in Analytic Philosophy: Reflections on Social Injustice and Oppression, Berlin, Boston: De Gruyter. doi: 10.1515/9783110612318

Résumé :
A new wave of thinkers from across different disciplines within the analytical tradition in philosophy has recently focused on critical, societal challenges, such as the silencing and questioning of the credibility of oppressed groups, the political polarization that threatens the good functioning of democratic societies across the globe, or the moral and political significance of gender, race, or sexual orientation. Appealing to both well-established and younger international scholars, this volume delves into some of the most relevant problems and discussions within the area, bringing together for the first time different essays within what we deem to be a “political turn in analytic philosophy.” This political turn consists of putting different conceptual and theoretical tools from epistemology, philosophy of language, philosophy of mind, and metaphysics at the service of social and political change. The aim is to ensure a better understanding of some of the key features of our social environments in an attempt to achieve a more just and equal society.

Lena Klever, Pascal Mamassian & Jutta Billino (2022). Age-related differences in visual confidence are driven by individual differences in cognitive control capacities. Sci Rep 12, 6016. doi: 10.1038/s41598-022-09939-7

Résumé:
Visual perception is not only shaped by sensitivity but also by confidence, i.e., the ability to estimate the accuracy of a visual decision. Younger observers have been reported to have access to a reliable measure of their own uncertainty when making visual decisions. This metacognitive ability might be challenged during ageing due to increasing sensory noise and decreasing cognitive control resources. We investigated age effects on visual confidence using a visual contrast discrimination task and a confidence forced-choice paradigm. Younger adults (19–38 years) showed significantly lower discrimination thresholds than older adults (60–78 years). To focus on confidence sensitivity above and beyond differences in discrimination performance, we estimated confidence efficiency that reflects the ability to distinguish good from bad perceptual decisions. Confidence efficiency was estimated by comparing thresholds obtained from all trials and trials that were judged with relatively higher confidence, respectively. In both age groups, high confidence judgments were associated with better visual performance, but confidence efficiency was reduced in older adults. However, we observed substantial variability across all participants. Controlling for age group, confidence effciency was closely linked to individual differences in cognitive control capacities. Our findings provide evidence for age-related differences in confidence efficiency that present a specific challenge to perceptual performance in old age. We propose that these differences are driven by cognitive control capacities, supporting their crucial role for metacognitive efficiency.

Mathilde Mus, Alexander Bor, & Michael Bang Petersen. (2022). Do conspiracy theories efficiently signal coalition membership? An experimental test using the “Who Said What?” design. PloS one, 17(3)e0265211

Résumé :
Theoretical work in evolutionary psychology have proposed that conspiracy theories may serve a coalitional function. Specifically, fringe and offensive statements such as conspiracy theories are expected to send a highly credible signal of coalition membership by clearly distinguishing the speaker’s group from other groups. A key implication of this theory is that cognitive systems designed for alliance detection should intuitively interpret the endorsement of conspiracy theories as coalitional cues. To our knowledge, no previous studies have empirically investigated this claim. Taking the domain of environmental policy as our case, we examine the hypothesis that beliefs framed in a conspiratorial manner act as more efficient coalitional markers of environmental position than similar but non-conspiratorial beliefs. To test this prediction, quota sampled American participants (total N = 2462) completed two pre-registered Who-Said-What experiments where we measured if participants spontaneously categorize targets based on their environmental position, and if this categorization process is enhanced by the use of a conspiratorial frame. We find firm evidence that participants categorize by environmental position, but no evidence that the use of conspiratorial statements increases categorization strength and thus serves a coalitional function.
