The where and when of linguistic word-level prosody.

Published: June 2007

Despite its presence in all natural languages prosodic processing remains under-researched in cognitive science. Hemispheric specialisation for linguistic word-level prosody, specifically, sensitivity to stress typicality was examined using dichotic listening. In Experiment 1, participants named targets and in Experiment 2 participants classified targets as nouns or verbs. In both studies stress typicality effects emerged in the left hemisphere only. These results suggest that: (1) the left hemisphere may be responsible for conveying accurate stress patterns prior to lexical access, (2) supra-segmental information reduces the set of potential candidates during lexical access, and (3) prosody and grammatical category interact in the language processing system.

Assessing early vocabulary development commonly involves parent report methods and behavioral tasks like looking-while-listening. While both yield reliable aggregate scores, findings are mixed regarding their reliability in measuring infants' knowledge of individual words. Using archival data from 126 monolingual and bilingual 14-31-month-olds, we further examined links across these methods at the word level, while controlling for potentially confounding child-level factors.

Article Synopsis
  • * The study analyzed EEG data from participants learning an artificial language, comparing those who slept for 8 hours to those who stayed awake, finding sleep improved understanding of sequence-based word order rules.
  • * Results indicated that sleep enhanced memory consolidation and retrieval related to language, showing a link between brain activity during sleep and wakefulness through specific neural oscillations.

Phonological Awareness and Word Decoding Skills in the Early Readers of Kannada.

Dept. of Audiology and Speech-Language Pathology, Kasturba Medical College Mangalore, Manipal Academy of Higher Education, Karnataka, Manipal, 576 104, India.

Background: Phonological awareness has been recognized as a significant predictor of word-decoding skills in alphabetical languages. These languages differ in phonology, orthography, and how they are mapped for word decoding. However, the literature has debated its role in orthographically consistent languages.

Human intelligence can safeguard against artificial intelligence: individual differences in the discernment of human from AI texts.

Sci Rep

October 2024

Department of Psychology and Neuroscience, Temple University, Weiss Hall, 1701 N. 13th St, Philadelphia, PA, 19122, USA.

Artificial intelligence (AI) models can produce output that closely mimics human-generated content. We examined individual differences in the human ability to differentiate human- from AI-generated texts, exploring relationships with fluid intelligence, executive functioning, empathy, and digital habits. Overall, participants exhibited better than chance text discrimination, with substantial variation across individuals.

The vocabularies of natural languages harbour many instances of iconicity, where words show a perceived resemblance between aspects of form and meaning. An open challenge in this domain is how to reconcile different operationalizations of iconicity and link them to an empirically grounded theory. Here we combine three ways of looking at iconicity using a set of 239 iconic words from 5 spoken languages (Japanese, Korean, Semai, Siwu and Ewe).
