EmoLexPros: A database of prosodically incongruent emotional words in European Portuguese

Abstract

In this study, we validated a set of audio stimuli addressing emotional lexico-prosodic congruence. Positive, neutral and negative words classified as such in European Portuguese lexical databases were recorded with matching and mismatching emotional prosodic patterns (positive, neutral and negative). The produced set was submitted to behavioral validation, where each utterance was rated for lexico-prosodic match. Word pairs showing maximal differences across match and mismatch versions were selected (n=55) and subjected to prosody-related acoustic validation. The three types of prosodic patterns, positive, negative and neutral, differenced in F0, amplitude, duration and timbral parameters. Finally, items were catalogued for their psycholinguistic properties. The present validated set may be used for emotional prosody research in European Portuguese. Since it is compatible with passive listening tasks, it is particularly relevant to research and clinical practice engaging populations who are limited in their ability to provide explicit responses.

Production of nouns and adjectives of children with cochlear implants and of children with typical hearing

“…This study shows, therefore, that the behaviour of the two groups, the children with CIs and the children with TH, did not differ in the number of non-responses of nouns and adjectives, nor in the superior number of correct productions of nouns versus adjectives in the picture naming activity. According to Serra et al [ 24 ], nouns constitute the broadest category of the repertoire of words acquired by children, a fact that justifies that the number of correct productions of nouns was greater than that of adjectives, since this semantic category does not appear as frequently in their vocabulary [ 25 , 26 , 28 ].…”

“…However, it has been found that parents infrequently ask “What is it like?” or “What's happening to it?” which would provoke the semantic production of adjectives [ 24 ]. Studies that compared children's production of both types of words showed a higher frequency of nouns than of adjectives [ 25 , 26 ]. Cutillas & Tolchinsky [ 27 ] observed an increase, with age, in the production of adjectives in narrative discourse, especially after 11 years of age.…”

Increased Pre-Boundary Lengthening Does Not Enhance Implicit Intonational Phrase Perception in European Portuguese: An EEG Study

“…Following the CPS paradigm, we created a set of 48 European Portuguese sentence pairs, which either had the potential to generate one phrase boundary (two clauses, A version) or two (three clauses, B version). These were syntactically simple declarative sentences composed of high-frequency words (frequency data taken from the Porlex database [ 21 ]), verbs, and other syntactic constituents such as “and” or “but”. The two sentences in each pair had similar lexical content, and they were matched for the number of words and syllables (for A versions, mean number of syllables = 25.0; SD = 2.4; for B versions, mean number of syllables = 25.3; SD = 2.1).…”

Dentro ou fora da norma: Estudos normativos no contexto da validação de estímulos

“… Palavras (Gomes et al, 2022) ou frases variáveis em prosódia emocional (Castro & Lima, 2010)  Excertos musicais (Guedes et al, 2023) É importante mencionar que estas bases são muito heterogéneas relativamente ao número de estímulos incluídos. Por exemplo, considerando estudos normativos de fotografias, as bases variam entre 50 e 120 fotografias de animais (Prada et al, 2014e Possidónio et al, 2019 e 1182 fotografias no caso da validação Portuguesa do International Affective Picture System (Soares et al, 2015b).…”
