The mere presence of task-irrelevant auditory stimuli is known to interfere with cognitive functioning. Disruption can be caused by changing auditory distractors (the changing-state effect) or by a sound that deviates from the auditory background (the deviation effect). The unitary account of auditory distraction explains both phenomena in terms of attentional capture whereas the duplex-mechanism account posits that they reflect two fundamentally different forms of distraction in which only the deviation effect is caused by attentional capture. To test these predictions, we exploited a physiological index of attention orienting: the pupillary dilation response (PDR). Participants performed visual serial recall while ignoring sequences of spoken letters. These sequences either comprised repeated or changing letters, and one letter could sometimes be replaced by pink noise (the deviant). Recall was poorer in both changing-state and deviant trials. Interestingly, the PDR was elicited by deviant sounds but not changing-state sounds, while a tonic increase in pupil size was found throughout changing-state trials. This physiological dissociation of the changing-state and the deviation effects suggests they are subtended by distinct mechanisms thereby procuring support for the duplex-mechanism account over the unitary account.

Towards personalized immersive virtual reality neurorehabilitation: a human-centered design.
J Neuroeng Rehabil

Dept. of Cognitive Robotics, TU Delft, Delft, Netherlands.
Background: Head-mounted displays can be used to offer personalized immersive virtual reality (IVR) training for patients who have suffered an Acquired Brain Injury (ABI) by tailoring the complexity of visual and auditory stimuli to the patient's cognitive capabilities. However, it is still an open question how these virtual environments should be designed.
Methods: We used a human-centered design approach to help define the characteristics of suitable virtual training environments for ABI patients.
The role of spatial location in irrelevant speech revisited: A preregistered replication study.

The goal of the present investigation was to perform a registered replication of Jones and Macken's (1995b) study, which showed that the segregation of a sequence of sounds to distinct locations reduced the disruptive effect on serial recall. Thereby, it postulated an intriguing connection between auditory stream segregation and the cognitive mechanisms underlying the irrelevant speech effect. Specifically, it was found that a sequence of changing utterances was less disruptive in stereophonic presentation, allowing each auditory object (letters) to be allocated to a unique location (right ear, left ear, center), compared to when the same sounds were played monophonically.

Movie-watching is a central aspect of our lives and an important paradigm for understanding the brain mechanisms behind cognition as it occurs in daily life. Contemporary views of ongoing thought argue that the ability to make sense of events in the 'here and now' depend on the neural processing of incoming sensory information by auditory and visual cortex, which are kept in check by systems in association cortex. However, we currently lack an understanding of how patterns of ongoing thoughts map onto the different brain systems when we watch a film, partly because methods of sampling experience disrupt the dynamics of brain activity and the experience of movie-watching.

Hearing is an active process in which listeners must detect and identify sounds, segregate and discriminate stimulus features, and extract their behavioral relevance. Adaptive changes in sound detection can emerge rapidly, during sudden shifts in acoustic or environmental context, or more slowly as a result of practice. Although we know that context- and learning-dependent changes in the sensitivity of auditory cortical (ACX) neurons support many aspects of perceptual plasticity, the contribution of subcortical auditory regions to this process is less understood.

Article Synopsis
- ASMR is a sensory phenomenon that creates tingling sensations through specific auditory or visual triggers, showing promise for reducing anxiety and enhancing relaxation in orthodontics.
- ASMR has physiological benefits, including lower heart rates and improved mood, and can help manage dental anxiety by providing personalized sensory experiences tailored to individual patient preferences.
- The use of ASMR during orthodontic procedures could improve patient comfort and compliance, highlighting the potential of this technique as a cost-effective therapeutic tool within dental settings.
