Oral random number generation is a widely used neuropsychological task engaging a number of overlapping neural systems of attention, number representation, response generation, and working memory. Although phonological processing is known to be essential for random number generation no information exists on the significance of the auditory feedback of hearing one's own voice on task performance. We therefore examined the influence of auditory feedback in 15 profoundly deaf adults with cochlear implants in a device-on/off experiment. No significant effects of occluding auditory feedback on random number generation were noted, thus supporting an internal response-monitoring model independent of auditory condition.

Generative models have diverse applications, including language processing and birdsong analysis. In this study, we demonstrate how a statistical test, designed to prevent overgeneralization in sequence generation, can be used to infer minimal models for the syllable sequences in Bengalese finch songs. We focus on the partially observable Markov model (POMM), which consists of states and the probabilistic transitions between them.

Research into new solutions for wearable assistive devices for the visually impaired is an important area of assistive technology (AT). This plays a crucial role in improving the functionality and independence of the visually impaired, helping them to participate fully in their daily lives and in various community activities. This study presents a bibliometric analysis of the literature published over the last decade on wearable assistive devices for the visually impaired, retrieved from the Web of Science Core Collection (WoSCC) using CiteSpace, to provide an overview of the current state of research, trends, and hotspots in the field.

Adapting one's speaking style is particularly crucial as children start interacting with diverse conversational partners in various communication contexts. The study investigated the capacity of preschool children aged 3-5 years ( = 28) to modify their speaking styles in response to background noise, referred to as noise-adapted speech, and when talking to an interlocutor who pretended to have hearing loss, referred to as clear speech. We examined how two modified speaking styles differed across the age range.

Article Synopsis
- The online experiment tested how delayed auditory feedback impacts participants' feelings of control (agency) over tone sequences.
- Participants practiced reproducing sequences with either immediate or delayed feedback and were later subjected to a scenario where the computer sometimes took over generating tones.
- Results showed that both agency and simultaneity judgments shifted after experiencing the delay, but the agency judgment changed more significantly, confirming Sugano's earlier findings and demonstrating the potential of online experiments in studying agency.
Probing Sensorimotor Memory through the Human Speech-Audiomotor System.

Our knowledge of human sensorimotor learning and memory is predominantly based on the visuo-spatial workspace and limb movements. Humans also have a remarkable ability to produce and perceive speech sounds. We asked if the human speech-auditory system could serve as a model to characterize retention of sensorimotor memory in a workspace which is functionally independent of the visuo-spatial one.
