 AB    The central executive component (CE) of Baddeley's working memory model
       (Baddeley, 1992) was evaluated in 26 asymptomatic human immunodeficiency
       virus-infected individuals (HIV+) and 23 HIV-control subjects using a
       dual-task working memory paradigm. The HIV+ and HIV- groups showed an
       equivalent reduction in performance on both the primary task (visual
       vigilance) and the secondary task (letter span) when they were performed
       concurrently relative to when either task was performed alone. This
       result suggested normal CE functioning in these HIV+ subjects. In
       contrast, the HIV+ subjects had significantly longer response latencies
       on reaction time measures relative to the HIV- control group. These
       findings indicated that slowed processing in early stage HIV-infected
       individuals is not associated with a working memory deficit.
