Auditory discrimination, memory, and attention-related functions were investigated in healthy 2-3-year-olds by recording event-related potentials (ERPs) to changes in five auditory features and two types of novel sounds using the fast multifeature paradigm (MFP). ERP profiles consisting of the mismatch negativity (MMN), P3a, and prominent late discriminative negativities (LDN) were obtained, for the first time, from this age group in a considerably shorter time compared to the traditional paradigms. Statistically significant responses from individual children were obtained mainly for the novel sounds. Thus, the MFP shows promise as a time-efficient paradigm for investigating central auditory functions in toddlers.

Previous investigations have shown pitch-based correspondences with various perceptual and conceptual attributes. The present study reveals two novel pitch-based correspondences with highly abstract concepts. Three experiments with varying levels of implicitness of the association task showed that the concepts of future and in are associated with high-pitch sounds, while past and out are associated with low-pitch sounds.

Noise pollution is a known health risk factor and evidence for cardiovascular diseases associated with traffic noise is growing. At least 20% of the European Union's population lives in noise-polluted areas with exposure levels exceeding the recommended limits of the World Health Organization, which is considered unhealthy by the European Environment Agency. This results in the annual loss of 1.

The aim of the study was to find whether certain meaningful moments in the learning process are noticeable through features of voice and how acoustic voice analyses can be utilized in learning research. The material consisted of recordings of nine university students as they were completing tasks concerning direct electric circuits as part of their course of teacher education in physics. Prosodic features of voice-fundamental frequency (F0), sound pressure level (SPL), acoustic voice quality measured by LTAS, and pausing-were investigated.

Experiencing music often entails the perception of a periodic beat. Despite being a widespread phenomenon across cultures, the nature and neural underpinnings of beat perception remain largely unknown. In the last decade, there has been a growing interest in developing methods to probe these processes, particularly to measure the extent to which beat-related information is contained in behavioral and neural responses.
