    Background and Objectives: Speech-in-noise testing is essential for evaluating functional hearing abilities in clinical practice. Although the Quick Speech-in-Noise test (QuickSIN) is widely used, no equivalent tool existed for European Portuguese. This study aimed to develop a Speech-in-Noise Test for European Portuguese (SiN-EP), linguistically adapted and calibrated for native speakers, to support clinical assessment of speech perception in realistic listening environments. Materials and Methods: The SiN-EP was developed through a multi-stage process. Sentences were drafted to reflect natural speech patterns and reviewed by native speakers for clarity and grammatical accuracy. Selected sentences were recorded by a female native speaker in a controlled acoustic environment and mixed with multi-talker babble at signal-to-noise ratios (SNR (dB)) from 25 to 0 SNR (dB). A pre-test in a free-field setting at 65 dB SPL was conducted with fifteen normal-hearing young adults. Participants repeated each sentence, and their responses were analyzed to refine list composition, adjust difficulty, and ensure phonetic balance. Results: Intelligibility decreased systematically as SNR (dB) worsened, with ceiling effects at 25 and 20 SNR (dB). At 5 SNR (dB), high variability was observed, with set 5 showing disproportionate difficulty and set 14 containing an incomplete sentence; both were removed. At 0 SNR (dB), all sets demonstrated expected low intelligibility. The final test comprises thirteen lists of six sentences, each maintaining stable intelligibility, phonetic representativeness, and consistent difficulty across SNRs (dB). Conclusions: The SiN-EP provides a linguistically appropriate, phonetically balanced, and SNR (dB) calibrated instrument for assessing speech-in-noise perception in European Portuguese. The refinement process improved reliability and list equivalence, supporting the test’s clinical and research applicability. The SiN-EP fills a critical gap in assessing speech-in-noise perception in European Portuguese speakers, providing a reliable tool for both clinical and research applications.

  • A importância da afetividade na aprendizagem da leitura e da escrita na cooperativa "A Torre"
    Publication . Vicente, Joana; Garcia, Maria
    O presente Relatório Final emerge da unidade curricular da Prática de Ensino Supervisionado. A investigação realizada para a sua execução foi feita numa turma de 1° ano de escolaridade, envolvendo crianças com idades compreendidas entre os seis e os sete anos. O tema deste relatório final, a Importância da Afectividade na Aprendizagem da Leitura e da Escrita, resulta da necessidade de compreender qual a importância, qual o valor e quais as consequências do afecto na aprendizagem. O objectivo deste estudo consiste na compreensão da importância e das consequências que o afecto, quando utilizado em contexto de sala de aula, traz à criança e às suas aprendizagens. A metodologia que me permitiu elaborar esta investigação foi de carácter qualitativo, tendo sido os instrumentos utilizados a observação, as notas de campo, recolha de dados e entrevistas semiestruturadas a professores. Para que as questões associadas ao problema identificado fossem respondidas, foi necessário proceder a uma pesquisa teórica perante a visão de vários autores. Para além da pesquisa, foi necessário também reflectir sobre as actividades realizadas com as crianças em contexto de sala, as notas de campo, assim como a entrevista realizada aos professores.
