Crynodeb o'r ymchwil
Fy mhrif faes ymchwil yw seicoleg agweddau. O fewn y maes hwn, mae gennyf nifer o ddiddordebau ymchwil, gan gynnwys: (a) rôl prosesau affeithiol a gwybyddol mewn agweddau, (b) amwysedd agweddau, (c) sut mae gwahaniaethau unigol yn dylanwadu ar brosesau agweddau, (d) sut mae salience plant yn dylanwadu ar ymddygiad ac (e) sut mae pobl yn cynrychioli gwrthrychau agwedd yn feddyliol. Mae'r ymchwil hon yn cael ei gynnal mewn cydweithrediad â chydweithwyr ym Mhrifysgol Caerdydd, Prifysgol Caerfaddon, yn ogystal â chydweithwyr yn Israel, yr Eidal a'r Iseldiroedd.
Crynodeb addysgu
Ym mlwyddyn 2, rwy'n addysgu ar y modiwl Seicoleg Gymdeithasol, lle mae fy narlithoedd yn ymdrin â phynciau altrusiaeth, ymddygiad ymosodol, ac ymddygiad iechyd.
Yn y flwyddyn olaf, rwy'n addysgu ac yn gwasanaethu fel cydlynydd modiwl ar gyfer PS3403 - Attitudes and Attitude Change. Nodau'r modiwl yw: (a) datblygu dealltwriaeth myfyrwyr o'r cysyniad o agwedd a'i bwysigrwydd mewn seicoleg gymdeithasol a (b) gwneud myfyrwyr yn gyfarwydd â damcaniaethau agwedd ac, yn arbennig, yr ymchwil a ddefnyddiwyd i brofi'r damcaniaethau hyn .
Mae goruchwyliaeth prosiect israddedig ac ôl-raddedig ym maes seicoleg agweddau.

Ymchwil
Pynciau ymchwil a phapurau cysylltiedig
Mae fy ymchwil yn canolbwyntio ar seicoleg agweddau. Mae gen i ddiddordeb mewn cwestiynau fel sut rydyn ni'n ffurfio a threfnu ein barn? Sut mae ein barn yn newid ac yn esblygu dros amser? Er enghraifft, dyma wahanol fathau o gwestiynau rydw i wedi bod yn eu hastudio:
Sut mae gwahanol bobl yn ymateb i wahanol fathau o apeliadau perswadiol?
Pan oeddwn i'n tyfu i fyny, roedd cyfres o hysbysebion teledu enwog lle roedd cyn-athletwyr proffesiynol yn dyrchafu eu ffafriaeth am frand penodol o gwrw. Er bod rhai o'r athletwyr yn nodi bod y cwrw yn blasu'n wych, atebodd eraill ei fod yn llai llenwi na chwrw eraill. O safbwynt agweddau, Mae rhan gyntaf y neges yn tynnu sylw at ymateb affeithiol cadarnhaol sy'n gysylltiedig â'r ddiod (h.y., ei flas), tra bod yr ail ran yn tynnu sylw at nodwedd gadarnhaol am y ddiod (h.y. ei gymeriant calorig isel). Gan ddefnyddio'r gymhariaeth hon, mae fy nghydweithwyr a minnau wedi bod â diddordeb mewn gwybod a yw rhai pobl yn cael eu perswadio'n fwy gan apêl affeithiol ac eraill yn fwy argyhoeddedig gan apêl wybyddol (gweler Haddock & Maio, 2019; Maio et al., 2025).
Sut mae pobl yn cynrychioli gwrthrychau agwedd yn feddyliol?
Rwyf wedi dod â diddordeb yn sut mae pobl yn cynrychioli gwrthrychau agwedd yn feddyliol. Pan fyddwch chi'n gofyn i wahanol bobl feddwl am grŵp (e.e., pobl o Ganada) neu gysyniad (e.e., narcissism), i ba raddau mae'r cynrychioliadau hyn yn wahanol, ac i ba raddau mae gwahaniaethau o'r fath yn bwysig? Gan ddefnyddio cydberthynas gwrthdro, rydym wedi canfod bod pobl yn cynrychioli gwrthrychau yn feddyliol ac yn weledol mewn ffyrdd gwahanol iawn, a bod y gwahaniaethau hyn yn cael canlyniadau pwysig ar ganfyddiad ac ymddygiad cymdeithasol (gweler ee, Han et al., 2023; Itzchakov et al., 2025; Proulx et al., 2023; Magazin et al., 2025; Smith et al., 2025).
Sut mae salience plant yn dylanwadu ar ymddygiad? Beth mae oedolion yn ei feddwl am blant?
Mewn un llinyn o waith, mae fy nghydweithwyr a minnau wedi ymchwilio i sut mae meddwl am blentyn yn dylanwadu ar affaith, gwybyddiaeth ac ymddygiad. Er enghraifft, rydym wedi darganfod bod paratoi pobl gyda'r cysyniad o blant yn arwain at fwy o bwysigrwydd a roddir i werthoedd hunan-drosgyniad a llai o bwysigrwydd a roddir i werthoedd hunan-wella (Wolf et al., 2022). Mewn ymchwil arall, rydym wedi datgelu agweddau oedolion tuag at blant, a chanlyniadau'r agweddau hyn (Wolf et al., 2024).

Grŵp ymchwil
Rwy'n aelod o'r grŵp ymchwil seicoleg gymdeithasol ac amgylcheddol .
Cydweithwyr ymchwil
O fewn yr Ysgol, fy mhrif gydweithwyr yw Thomas Vaughn-Johnston, Travis Proulx, ac Ulrich von Hecker. Mae cydweithwyr allanol diweddar yn cynnwys cydweithwyr o Brifysgol Caerfaddon, Prifysgol y Ddinas, Prifysgol Reading a Phrifysgol Essex. Cydweithrediadau rhyngwladol gyda chydweithwyr yn Israel, yr Eidal a'r Iseldiroedd.
Addysgu
Ym mlwyddyn 2, rwy'n dysgu ar y modiwl Seicoleg Gymdeithasol, lle mae fy narlithoedd yn ymdrin â'r pynciau o helpu ymddygiad, ymddygiad ymosodol, ac ymddygiad iechyd.
Yn y flwyddyn olaf, rwy'n addysgu ar y modiwl Agweddau a Newid Agwedd. Nodau'r modiwl yw: (a) datblygu dealltwriaeth myfyrwyr o'r cysyniad o agwedd a'i bwysigrwydd mewn seicoleg gymdeithasol a (b) gwneud myfyrwyr yn gyfarwydd â damcaniaethau agwedd ac, yn enwedig, yr ymchwil a ddefnyddiwyd i brofi'r damcaniaethau hyn .
Mae goruchwylio prosiect ym maes seicoleg agweddau.
Bywgraffiad
Addysg israddedig
Mynychais Brifysgol Toronto, lle cefais fy B.Sc. yn 1989.
Addysg ôl-raddedig
Cwblheais fy Ph.D. ym Mhrifysgol Waterloo. Roedd fy nhraethawd Ph.D. yn archwilio i ba raddau y mae gwybodaeth affeithiol a gwybyddol yn dylanwadu ar agweddau ar draws unigolion. Ar ôl cwblhau fy Ph.D., treuliais flwyddyn fel cymrawd ôl-ddoethurol ym Mhrifysgol Michigan cyn symud i'r Deyrnas Unedig ym 1995.

Diddordebau ymchwil ôl-raddedig
Fy mhrif faes ymchwil yw seicoleg agweddau. Yn y maes hwn, mae gennyf nifer o ddiddordebau ymchwil, gan gynnwys: (a) rôl prosesau affeithiol a gwybyddol mewn agweddau, (b) yr effaith ar ymwybyddiaeth ofalgar ar agweddau a newid agwedd, (c) agwedd amwysedd, (d) sut mae gwahaniaethau unigol yn dylanwadu ar brosesau agwedd, a (e) sut mae halltedd plant yn dylanwadu ar ymddygiad.
Os oes gennych ddiddordeb mewn gwneud cais am PhD, neu am ragor o wybodaeth am fy ymchwil ôl-raddedig, cysylltwch â mi'n uniongyrchol (manylion cyswllt ar gael ar y dudalen 'Trosolwg'), neu gyflwyno cais ffurfiol.
