Learning General Phonological Rules From Distributional Information: A Computational Model

Phonological rules create alternations in the phonetic realizations of related words. These rules must be learned by infants in order to identify the phonological inventory, the morphological structure, and the lexicon of a language. Recent work proposes a computational model for the learning of one kind of phonological alternation, allophony (Peperkamp, Le Calvez, Nadal, & Dupoux, 2006). This paper extends the model to account for learning of a broader set of phonological alternations and the formalization of these alternations as general rules. In Experiment 1, we apply the original model to new data in Dutch and demonstrate its limitations in learning nonallophonic rules. In Experiment 2, we extend the model to allow it to learn general rules for alternations that apply to a class of segments. In Experiment 3, the model is further extended to allow for generalization by context; we argue that this generalization must be constrained by linguistic principles.     

Resilience matters: Explaining the association between personality and psychological functioning during the COVID-19 pandemic

Background/ObjectiveThe objective of the study was to elucidate the underlying mechanism through which basic personality dimensions predict indicators of psychological functioning during the COVID-19 pandemic, including subjective well-being and perceived stress. As a personality characteristic highly contextualized in stressful circumstances, resilience was expected to have a mediating role in this relationship. Method: A sample of 2,722 Slovene adults, aged from 18 to 82 years filled in the Big Five Inventory, the Connor-Davidson Resilience Scale, the Perceived Stress Scale, and the Mental Health Continuum. A path analysis with the Bootstrap estimation procedure was performed to evaluate the mediating effect of resilience in the relationship between personality and psychological functioning. Results: Resilience fully or partially mediated the relationships between all the Big Five but extraversion with subjective well-being and stress experienced at the beginning of the COVID-19 outburst. Neuroticism was the strongest predictor of less adaptive psychological functioning both directly and through diminished resilience. Conclusions: Resilience may be a major protective factor required for an adaptive response of an individual in stressful situations such as pandemic and the associated lockdown.
