Objective: Hearing loss in the older adult population is a significant global health issue. Hearing aids can provide an effective means to address hearing loss and improve quality of life. Despite this, the uptake and continued use of hearing aids is low, with non-use of hearing aids representing a significant problem for effective audiological rehabilitation.

- Human balance relies on the nervous system's ability to estimate self-motion for detecting and responding to unexpected movements, which involves adjustments for sensory and motor delays.
- A robotic system was used to simulate standing balance and introduce these delays, which initially caused instability and increased uncertainty in participants' balance perceptions.
- After training, participants adapted to the delays, improving their balance by linking sensory feedback with their motor commands, resulting in a partial return of vestibular contributions to a more stable state.
The long-latency "reflexive" response (LLR) following an upper limb mechanical perturbation is generated by neural circuitry shared with voluntary control. This feedback response supports many task-dependent behaviors and permits the expression of goal-directed corrections at latencies shorter than voluntary reaction time. An extensive body of literature has demonstrated that the LLR shows flexibility akin to voluntary control, but it has not yet been tested whether instruction-dependent LLR changes can also occur in the absence of an overt voluntary response.

This "response complexity effect" has typically been attributed to increased time required to prepare some aspect of the response; however, most studies examining the response complexity effect have used an unpredictable foreperiod, which does not allow for optimal preparation to occur. Thus, it is conceivable that response complexity effects are influenced by an inability to predict the occurrence of the go-signal.
