Final answer:
Both positive and negative aspects can be seen in the characteristics of the triad of impairments in autism in the given scenarios.
Step-by-step explanation:
In both scenarios, the characteristics of the triad of impairments seen in autism can be seen as both positive and negative.
In the case of Rashid, his limited verbal communication and use of pictures to communicate his needs can be seen as positive because it allows him to effectively express himself and make his needs known to his teaching and support staff. His hypersensitivity to touch and resistance to change, on the other hand, can be seen as negative because they restrict his comfort and flexibility in different situations.
Similarly, in the case of Josh, his good verbal communication skills and ability to share his knowledge about computers can be seen as positive as it allows him to engage with others and pursue his interests. However, his literal interpretation of spoken and written text and his inability to understand social cues can be seen as negative because it may affect his communication and social interactions with others.
