The last decade has seen significant growth in scientific understanding and public awareness of autism. There is still a long road ahead before this awareness can be matched with parallel improvements in evidence-based practice. The process of translating evidence into community care has been hampered by the seeming disconnect between the mainstream scientific research agenda and the immediate priorities of many communities. The need for community engagement in the process of translating knowledge into impact has been recognized. However, there remains little consensus or empirical data regarding the process of such engagement and how to measure its impact. We shed light on a number of engagement models and tools, previously advocated in health research, as they apply to autism research. Furthermore, we illustrate the utility of such tools in supporting identification of knowledge gaps and priorities, using two community-based case studies. The case studies illustrate that information generated from research is indeed relevant and critical for knowledge users in the community. Simple and systematic methods can support the translation and uptake of knowledge in diverse communities, therefore enhancing engagement with research and bridging research findings with immediate community needs.

The stress of caring for a loved one with chronic illness has been linked with impairments in cognitive processes such as attention and problem solving, though few studies have examined the impact on memory. Compromised cognition, in particular, aspects of everyday functioning such as remembering medical instructions and appointments, might affect caregivers’ ability to maintain the consistency and quality of care needed by the child. A sample of 31 caregivers of children with autism and 51 parents of neuro-typical children completed an electronic survey assessing their levels of psychological distress and everyday memory. Perceived stress scores were higher in the caregiver group, as were self-reported memory failures for everyday tasks. The negative impact of caregiver stress on everyday memory was particularly salient among caregivers experiencing higher perceived levels of stress. These findings have implications for interventions that aim to improve caregivers’ cognitive well being through targeting the psychological sequelae associated with the caregiving experience.

3. Wallace MT, Stevenson RA. {{The construct of the multisensory temporal binding window and its dysregulation in developmental disabilities}}. {Neuropsychologia}. 2014.

Behavior, perception and cognition are strongly shaped by the synthesis of information across the different sensory modalities. Such multisensory integration often results in performance and perceptual benefits that reflect the additional information conferred by having cues from multiple senses providing redundant or complementary information. The spatial and temporal relationships of these cues provide powerful statistical information about how these cues should be integrated or « bound » in order to create a unified perceptual representation. Much recent work has examined the temporal factors that are integral in multisensory processing, with many focused on the construct of the multisensory temporal binding window – the epoch of time within which stimuli from different modalities is likely to be integrated and perceptually bound. Emerging evidence suggests that this temporal window is altered in a series of neurodevelopmental disorders, including autism, dyslexia and schizophrenia. In addition to their role in sensory processing, these deficits in multisensory temporal function may play an important role in the perceptual and cognitive weaknesses that characterize these clinical disorders. Within this context, focus on improving the acuity of multisensory temporal function may have important implications for the amelioration of the « higher-order » deficits that serve as the defining features of these disorders.
