At the 2018 John Slatin AccessU conference organized by Knowbility, I spoke about the wide variety of circumstances driving the cognitive abilities any of us have at any given moment. The difference between intelligence and cognitive ability, as well as the broad range and individual nature of cognitive abilities were explored. Attendees also had a brief look at the type of value offered by each of the new WCAG 2.1 Success Criteria containing benefits for people with cognitive impairments.
Variable is the constant in cognitive ability and it applies to a person as well as between different people. That variability creates a conundrum, the need for mutually exclusive or diametrically opposed solutions.
The talk acknowledges technology enhancements groups like the Global Public Inclusive Infrastructure and W3C are working on to resolve some of the more complex issues, and then offers techniques to consider now. Numerous ways for providing additional options or information to overcome the conundrum are offered. Each aims to open a broader spectrum of cognitive abilities necessary for successful perception, comprehension, recall, and interaction.
