Attention deficits have been documented as a relative weakness on the "freedom from distractibility" subclass of IQ tests (Brouwers et al, 1989) and on behavior assessment (Moss et al, 1994). Attention, however, has many subcomponents such as focused attention, divided attention, vigilance, etc. Direct assessment of attentional functioning using reaction time has not yet been conducted and questions whether attentional components are differentially affected by the virus have not been addressed.
