  • Missing data: VRM: 1 SLE, ERT: 1 SLE; RVP: 1 SLE; SWM: 2 SLE; OTS: 1 SLE.

  • P-values in bold are significant at <0.05.

  • *Higher scores indicate better performance except where indicated with a “+”.

  • ERT, emotional recognition task; OTS, one touch stockings; Pal, paired associate learning; RVP, rapid information visual processing; SWM, spatial working memory; VRM, verbal recognition memory.
