Listening to two-talker conversations in quiet settings: the role of listeners' cognitive processing capabilities for memory and listening effort.

Listening to conversing talkers in quiet environments and remembering the content is a common activity. However, research on the cognitive demands involved is limited. This study investigates the relevance of individuals' cognitive functions for listeners' memory of two-talker conversations and their listening effort in quiet listening settings.

How users make online privacy decisions in work and personal contexts of use.

With the rising usage of contactless work options since COVID-19, users increasingly share their personal data in digital tools at work. Using an experimental online vignette study (N = 93), we examined users' willingness to use a video conferencing tool, while systematically varying the context of use (personal vs. low trustworthiness work vs.

The effect of aggressive group norms on young adults' conformity behavior in WhatsApp chats: a vignette-based experiment.

Social networking and messaging applications, such as WhatsApp, have become an essential social environment for adolescents and young adults (AYA). While facilitating connectivity, they also bear hazards, including cyber-aggression. This study investigates the impact of (aggressive) group norms on AYA's propensity to expect cyberaggressive behaviors within different group chats.

A lecturer's voice quality and its effect on memory, listening effort, and perception in a VR environment.

Many lecturers develop voice problems, such as hoarseness. Nevertheless, research on how voice quality influences listeners' perception, comprehension, and retention of spoken language is limited to a small number of audio-only experiments. We aimed to address this gap by using audio-visual virtual reality (VR) to investigate the impact of a lecturer's hoarseness on university students' heard text recall, listening effort, and listening impression.

The effects of irrelevant speech on physiological stress, cognitive performance, and subjective experience - Focus on heart rate variability.

Irrelevant speech impairs cognitive performance, especially in tasks requiring verbal short-term memory. Working on these tasks during irrelevant speech can also cause a physiological stress reaction. The aim of this study was to examine heart rate variability (HRV) as a non-invasive and easy-to-use stress measure in an irrelevant speech paradigm.

The impact of a speaker's voice quality on auditory perception and cognition: a behavioral and subjective approach.

Introduction: Our voice is key for conveying information and knowledge to others during verbal communication. However, those who heavily depend on their voice, such as teachers and university professors, often develop voice problems, signaled by hoarseness. The aim of this study was to investigate the effect of hoarseness on listeners' memory for auditory-verbal information, listening effort, and listening impression.

Assemble it like this! - Is AR- or VR-based training an effective alternative to video-based training in manual assembly?

AR- and VR-based training is increasingly being used in the industry to train workers safely and effectively for new tasks. In this study, we investigated and compared the effects of AR-, VR- and video-based training on short- and long-term objective performance measures and subjective evaluations in a manual assembly task. Our results showed that there was no difference between AR-, VR- and video-based training concerning the objective performance measures task completion time and error count.

Differential Effects of Task-Irrelevant Monaural and Binaural Classroom Scenarios on Children's and Adults' Speech Perception, Listening Comprehension, and Visual-Verbal Short-Term Memory.

Most studies investigating the effects of environmental noise on children's cognitive performance examine the impact of monaural noise (i.e., same signal to both ears), oversimplifying multiple aspects of binaural hearing (i.

Irrelevant speech impairs serial recall of verbal but not spatial items in children and adults.

Immediate serial recall of visually presented items is reliably impaired by task-irrelevant speech that the participants are instructed to ignore ("irrelevant speech effect," ISE). The ISE is stronger with changing speech tokens (words or syllables) when compared to repetitions of single tokens ("changing-state effect," CSE). These phenomena have been attributed to sound-induced diversions of attention away from the focal task (attention capture account), or to specific interference of obligatory, involuntary sound processing with either the integrity of phonological traces in a phonological short-term store (phonological loop account), or the efficiency of a domain-general rehearsal process employed for serial order retention (changing-state account).

Effects of Augmented Reality-, Virtual Reality-, and Mixed Reality-Based Training on Objective Performance Measures and Subjective Evaluations in Manual Assembly Tasks: A Scoping Review.

Objective: The present scoping review aims to transform the diverse field of research on the effects of mixed reality-based training on performance in manual assembly tasks into comprehensive statements about industrial needs for and effects of mixed reality-based training.

Background: Technologies such as augmented and virtual reality, referred to as mixed reality, are seen as promising media for training manual assembly tasks. Nevertheless, current literature shows partly contradictory results, which is due to the diversity of the hardware used, manual assembly tasks as well as methodological approaches to investigate the effects of mixed reality-based training.

Does the Macro-Temporal Pattern of Road Traffic Noise Affect Noise Annoyance and Cognitive Performance?

Noise annoyance is usually estimated based on time-averaged noise metrics. However, such metrics ignore other potentially important acoustic characteristics, in particular the macro-temporal pattern of sounds as constituted by quiet periods (noise breaks). Little is known to date about its effect on noise annoyance and cognitive performance, e.

Character Customization With Cosmetic Microtransactions in Games: Subjective Experience and Objective Performance.

Free games that are monetized by selling virtual items, such as cosmetic microtransactions for one's avatar, seem to offer a better gaming experience to paying players. To experimentally explore this phenomenon, the effects of character customization with cosmetic microtransactions on objective and self-estimated player performance, subjective identification with the avatar, fun and the players' perceived competence were examined in the game League of Legends. This study introduces a new laboratory-based, experimental task to objectively measure within-game player performance.

The role of spatial separation of two talkers' auditory stimuli in the listener's memory of running speech: listening effort in a non-noisy conversational setting.

Objective: To investigate the role of the spatial position of conversing talkers, that is, spatially separated or co-located, in the listener's short-term memory of running speech and listening effort.

Design: In two experiments (between-subject), participants underwent a dual-task paradigm, including a listening (primary) task wherein male and female talkers spoke coherent texts. Talkers were either spatially separated or co-located (within-subject).

Audio-video virtual reality environments in building acoustics: An exemplary study reproducing performance results and subjective ratings of a laboratory listening experiment.

The present study adopted a human-centred approach to explore the potential of audio-video Virtual Reality (VR) to evaluate indoor noise protection by building characteristics. Different background speech conditions, convolved with sound insulation filters of adjacent office rooms, were presented in a VR office environment and the effects on cognitive performances and subjective ratings were measured. The found effect patterns were the same as those obtained in a real laboratory setting reported by Schlittmeier, Hellbrück, Thaden, and Vorländer.

Effects of Different Spectral Shapes and Amplitude Modulation of Broadband Noise on Annoyance Reactions in a Controlled Listening Experiment.

Environmental noise from transportation or industrial infrastructure typically has a broad frequency range. Different sources may have disparate acoustical characteristics, which may in turn affect noise annoyance. However, knowledge of the relative contribution of the different acoustical characteristics of broadband noise to annoyance is still scarce.

Short-term annoyance reactions to stationary and time-varying wind turbine and road traffic noise: A laboratory study.

Current literature suggests that wind turbine noise is more annoying than transportation noise. To date, however, it is not known which acoustic characteristics of wind turbines alone, i.e.

The effects of spectral and temporal parameters on perceived confirmation of an auditory non-speech signal.

In human-machine interactions, the confirmation of an action or input is a very important information for users. A paired comparison experiment explored the effects of four acoustic parameters on the perceived confirmation of auditory non-speech signals. Reducing the frequency-ratio and the pulse-to-pulse time between two successive pulses increased perceived confirmation.

Unmasking the effects of masking on performance: The potential of multiple-voice masking in the office environment.

Broadband noise is often used as a masking sound to combat the negative consequences of background speech on performance in open-plan offices. As office workers generally dislike broadband noise, it is important to find alternatives that are more appreciated while being at least not less effective. The purpose of experiment 1 was to compare broadband noise with two alternatives-multiple voices and water waves-in the context of a serial short-term memory task.

The impact of road traffic noise on cognitive performance in attention-based tasks depends on noise level even within moderate-level ranges.

Little empirical evidence is available regarding the effects of road traffic noise on cognitive performance in adults, although traffic noise can be heard at many offices and home office workplaces. Our study tested the impact of road traffic noise at different levels (50 dB(A), 60 dB(A), 70 dB(A)) on performance in three tasks that differed with respect to their dependency on attentional and storage functions, as follows: The Stroop task, in which performance relied predominantly on attentional functions (e.g.

What characterizes changing-state speech in affecting short-term memory? An EEG study on the irrelevant sound effect.

The irrelevant sound effect (ISE) describes reduced verbal short-term memory during irrelevant changing-state sounds which consist of different and distinct auditory tokens. Steady-state sounds lack such changing-state features and do not impair performance. An EEG experiment (N=16) explored the distinguishing neurophysiological aspects of detrimental changing-state speech (3-token sequence) compared to ineffective steady-state speech (1-token sequence) on serial recall performance.

Algorithmic modeling of the irrelevant sound effect (ISE) by the hearing sensation fluctuation strength.

Background sounds, such as narration, music with prominent staccato passages, and office noise impair verbal short-term memory even when these sounds are irrelevant. This irrelevant sound effect (ISE) is evoked by so-called changing-state sounds that are characterized by a distinct temporal structure with varying successive auditory-perceptive tokens. However, because of the absence of an appropriate psychoacoustically based instrumental measure, the disturbing impact of a given speech or nonspeech sound could not be predicted until now, but necessitated behavioral testing.

Combined effects of acoustic and visual distraction on cognitive performance and well-being.

Information work is usually performed in offices and influenced by the combined effects of acoustics, room climate, lighting and air quality. However, the principal part of literature solely focuses on the individual effects of physical parameters. This study (n = 32) investigates the combined effects of acoustic and visual distraction with regard to cognitive performance and well-being.

Can the irrelevant speech effect turn into a stimulus suffix effect?

The irrelevant sound effect (ISE) and the stimulus suffix effect (SSE) are two qualitatively different phenomena, although in both paradigms irrelevant auditory material is played while a verbal serial recall task is being performed. Jones, Macken, and Nicholls (2004) have proposed the effect of irrelevant speech on auditory serial recall to switch from an ISE to an SSE mechanism, if the auditory-perceptive similarity of relevant and irrelevant material is maximized. The experiment reported here (n = 36) tested this hypothesis by exploring auditory serial recall performance both under irrelevant speech and under speech suffix conditions.

Detrimental effects of irrelevant speech on serial recall of visual items are reflected in reduced visual N1 and reduced theta activity.

The term irrelevant sound effect (ISE) describes an empirically robust finding in which serial recall performance of visual items is reduced by irrelevant speech. At present little is known about its neurophysiological basis. Although some previous neuroelectric studies have concentrated on responses elicited by irrelevant background sound, whether the processing of visually presented to-be-remembered digits itself is affected by irrelevant speech has yet to be studied.
