The influence of lexical stress and/or metrical stress on spoken word recognition was examined. Two experiments were designed to determine whether response times in lexical decision or shadowing tasks are influenced when primes and targets share lexical stress patterns (JUVenile-BIBlical [Syllables printed in capital letters indicate those syllables receiving primary lexical stress.]). The results did not support an effect of lexical stress on the organization of lexical memory. In Experiment 3 primes and targets whose first syllables shared lexical stress only (MUDdy-PASta), metrical stress only (alTHOUGH-PASta), both cues (LECtern-PASta), or neither cue (conTROL-PASta) revealed no priming effect. However, targets whose first syllables were strong were responded to faster than targets whose first syllables were weak. Experiment 4 manipulated the metrical stress patterns of bi-syllabic primes and targets. Targets with strong-weak metrical stress patterns were responded to more quickly than those with strong-strong or weak-strong patterns. Although the priming paradigm did not reveal an influence of lexical and metrical stress on the organization of lexical memory, the data do support an influence of strong syllables on the processing of auditorily presented words.

Amplitude modulation structure in French and German poetry: universal acoustic physical structures underpin different poetic rhythm structures.
R Soc Open Sci

Centre for Neuroscience in Education, University of Cambridge, Cambridge, UK.
French and German poetry are classically considered to utilize fundamentally different linguistic structures to create rhythmic regularity. Their metrical rhythm structures are considered poetically to be very different. However, the biophysical and neurophysiological constraints upon the speakers of these poems are highly similar.

Article Synopsis
- The Implicit Prosody Hypothesis (IPH) suggests that people create internal vocal patterns while reading silently, similar to those used in spoken language.
- The study used EEG to analyze brain responses as participants read sequences of words with different stress patterns, revealing that unexpected stress in words triggered stronger brain reactions.
- Results indicated that various brain wave activities correlate with rhythmic expectations in language, supporting the idea that the same neural networks are involved in processing both spoken and silently read language.
Investigating a Metrical Hebb Effect for lists of words.
Q J Exp Psychol (Hove)
November 2024
University of Hertfordshire, Hatfield, UK.
Article Synopsis
- The study introduces the Metrical Hebb Effect, demonstrating that people can learn repeating stress patterns across familiar word sequences, even without identical words being repeated.
- Experiment 1 confirms this effect, showing significant retention of metrical patterns with repeated presentations.
- Further experiments explore the longevity of this learning, revealing that while it can persist after a few non-repeating lists, it fades with longer gaps, suggesting that the learning process involves chunking patterns rather than just memorizing item positions.
Hypoactivation of the language network during auditory imagery contributes to hallucinations in Schizophrenia.

Auditory verbal hallucinations (AVHs) involve perceptions, often voices, in the absence of external stimuli, and rank among the most common symptoms of schizophrenia. Metrical stress evaluation requires determination of the stronger syllable in words, and therefore requires auditory imagery, of interest for investigation of hallucinations in schizophrenia. The current functional magnetic resonance imaging study provides an updated whole-brain network analysis of a previously published study on metrical stress, which showed reduced directed connections between Broca's and Wernicke's regions of interest (ROIs) for hallucinations.

As the largest organ, the skin provides the first line of defence against environmental pollutants. Different pollutants have varied damage to the skin due to their own physical-chemical properties. A previous epidemiological study by our team revealed that eczema was positively correlated with different air pollutants.
