Trosolwg

Mae prosesau gwybyddol, fel y rhai sy'n ymwneud â chanfyddiad, cof a gwneud penderfyniadau, yn ddibynnol iawn ar eu cyd-destun. Mae profiadau, disgwyliadau a nodau blaenorol i gyd yn siapio sut mae mewnbwn synhwyraidd yn cael ei drawsnewid yn ganfyddiadau, sut mae atgofion yn cael eu storio a'u hadalw a sut mae'r wybodaeth sydd ar gael yn cael ei gwerthuso i arwain ymddygiad. Mae'r nodwedd hon o brosesu gwybodaeth ddynol yn hynod dreiddiol a gellir ei phrofi'n hawdd, yn enwedig mewn achosion pan fydd yn arwain at wallau. Er enghraifft, mae'n aml yn anodd adnabod wyneb cyfarwydd y tu allan i'w gyd-destun arferol (ffenomen "y cigydd ar y bws") ac mae ailadrodd gwallus geiriau ysgrifenedig yn aml yn ddisylw ("dallineb ailadrodd"; mae enghraifft wedi'i hymgorffori yn hyn brawddeg iawn).

Er gwaethaf arwain at wallau mewn rhai achosion, mae integreiddio cyd-destun â phrosesu cyfredol yn rhan annatod o wybyddiaeth oherwydd ei fod yn sylfaen ar gyfer dysgu ac ymddygiad addasol. Mae fy ymchwil yn ymchwilio i sut mae cyd-destun yn siapio prosesu gwybodaeth ddynol. I'r perwyl hwn, rwy'n mesur cywirdeb a chyflymder ymddygiad agored yn ogystal â gweithgaredd yn yr ymennydd dynol fel y'i hasesir gydag offer fel electroenceffalograffi (EEG), magnetoenceffalograffi (MEG) a recordiadau uniongyrchol o electrodau sy'n cael eu mewnblannu yn ymennydd cleifion niwrolawdriniaeth. Mae pwyslais penodol ar fy ngwaith ar ddatblygu cyfrifon damcaniaethol manwl gywir (modelau mathemategol) o brosesau gwybyddol sy'n cael eu llywio a'u cyfyngu gan ymddygiad agored pwyllog a gweithgaredd ymennydd.
