This study investigates the vertical localization of single complex tones (monads) and simultaneous complex tone pairs (dyads), especially as it is affected by their fundamental frequency and source elevation. Two complex tone timbres are considered: one consisting of five low-order harmonics, and the other of all odd harmonics (a square wave). Sound sources were at -15, 0, 15, and 30 deg from the horizontal plane at ear height. For eight subjects, this source array was in the median plane, and for a further nine subjects, it was directly to the subject's left (lateral plane). The subjects localized the angle of the auditory image(s) of one or two complex tones around the vertical plane containing the sound sources. Mean responses for the five-harmonic complex tones show a systematic effect (referred to as Pratt's effect) of fundamental frequency on vertical localization--whereby high-frequency complex tones are localized to positions higher than low-frequency complex tones for equivalent source positions. For the square wave, the sound-source position dominates localization, although some effect of fundamental frequency is evident for median plane sources.

The effects of cannabinoid agonism on auditory discrimination.
Behav Pharmacol
December 2024
Department of Psychology, Grand Valley State University, Allendale, Michigan, USA.
Recent evidence suggests that cannabis can impair simple auditory processes, and these alterations might be due to cannabinoid agonism. The effect of cannabinoid agonism on relatively complex processes such as auditory discrimination is unknown. The goal of this study was to examine the impact of WIN 55,212-2, a CB1 receptor and CB2 receptor agonism, on auditory discrimination using a go/no-go task.

Background: Given the public's tendency to overestimate the capability of artificial intelligence (AI) in surgical outcomes for plastic surgery, this study assesses the accuracy of AI-generated images for breast augmentation and reduction, aiming to determine if AI technology can deliver realistic expectations and can be useful in a surgical context.
Methods: We used AI platforms GetIMG, Leonardo, and Perchance to create pre- and postsurgery images of breast augmentation and reduction. Board-certified plastic surgeons and plastic surgery residents evaluated these images using 11 metrics and divided them into 2 categories: realism and clinical value.
The Relationship of Pitch Discrimination with Segregation of Tonal and Speech Streams for Cochlear Implant Users.
Trends Hear

Auditory Research Center, Caruso Department of Otolaryngology - Head and Neck Surgery, Keck School of Medicine, University of Southern California, Los Angeles, California, USA.
Cochlear implant (CI) users often complain about music appreciation and speech recognition in background noise, which depend on segregating sound sources into perceptual streams. The present study examined relationships between frequency and fundamental frequency (F0) discrimination with stream segregation of tonal and speech streams for CI users and peers with no known hearing loss. Frequency and F0 discrimination were measured for 1,000 Hz pure tones and 110 Hz complex tones, respectively.

Background: Growing awareness of social inequities and injustices in education highlights the urgent need to address harmful mechanisms, policies, and norms within health education curricula and systems.
Purpose: This study examines inclusivity and exclusivity content in four fundamental nursing textbooks and contributes to the broader discourse on fostering equitable health education.
Methods: A Directed Qualitative Content Analysis on 32 chapters from four fundamental nursing textbooks was systematically conducted.
Pitch-induced illusory percepts of time.
Atten Percept Psychophys
December 2024
Department of Psychology, Neuroscience and Behaviour, McMaster University, Hamilton, ON, Canada.
Past research suggests that pitch height can influence the perceived tempo of speech and music, such that higher-pitched signals seem faster than lower-pitched ones. However, previous studies have analyzed perceived tempo across a relatively limited range of fundamental frequencies. To investigate whether this higher-equals-faster illusion generalizes across the wider range of human hearing, we conducted a series of five experiments.
