Cognitive neuroscience literature suggests a strong dissociation between the ability to mentally transform object and body stimuli (Hegarty & Waller, 2004). However, little is known about how this ability changes with age. This dissociation was explored in 20 younger (19-24 years) and 20 older (65-87 years) adults. Mental rotation of object stimuli was demonstrated for both age groups, suggesting that the neuro-cognitive network involved with performing (object-based) mental transformations is relatively preserved in older age. Compared to young adults, older adults displayed the greatest decline in performance efficiency for the whole-body task. The authors propose that an age-related decline in the integrity of body-schema information may account for this change.

The associations between PTSD criterion symptoms and pain outcomes highlight the likely occurrence of shared mechanisms, particularly between the experience of severe pain, hyperarousal, avoidance, and cognitive appraisals of stress or pain. New efforts are required to develop and validate interventions that can effectively treat comorbid pain and PTSD to prevent their long-term impacts on psychological wellbeing and socioeconomic position.

The evidence supports the view that drivers with cognitive impairment do restrict their driving and avoid complex driving situations. However, it remains to be determined whether the drivers who engage in self-regulation have insight into their own driving abilities or whether external factors result in self-regulation of driving behaviour.
