Crynodeb ymchwil
Yr wyneb dynol yw ein prif organ cyfathrebu a mwyaf cyntefig. Mae fy ymchwil yn archwilio'r seicoleg o weld a bod yn berchen ar wyneb. Yn hyn, rwy'n mynd i'r afael ag ystod o gwestiynau. Mae'r rhain yn newydd (A yw Botox yn ein gwneud ni'n hapus? - A yw masgiau wyneb yn ein gwneud yn ddeniadol?) ac yn hynafol (Beth sy'n gwneud wyneb deniadol? - Pam mae wynebau newydd mor anodd eu cofio?). Mae fy nghwestiynau ymchwil yn ddamcaniaethol ("Sut ydyn ni'n storio wynebau yn y cof?), ac yn ymarferol (Sut ydyn ni'n adeiladu cyfansoddyn fforensig orau?). Mae'r cwestiynau hyn yn dod o fewn seicoleg gymdeithasol (Beth yw'r rhagfarnau cydnabod ar gyfer wynebau hil gymysg?), o fewn seicoleg wybyddol, (Sut mae arddull brosesu yn effeithio ar adnabod wyneb?), o fewn seicoleg fiolegol, (Sut mae cylchoedd mislif yn effeithio ar brosesu wyneb?) a niwroseicolegol (Sut mae niwroamrywiaeth yn effeithio ar brosesu wyneb?). Rwyf hefyd yn archwilio dilysrwydd a dibynadwyedd methodolegau gyda seicoleg yn fwy cyffredinol.

Effeithiau masgiau wyneb ar atyniad
Yn ystod covid, mae masgiau wyneb yn dod yn olygfa gyffredin. Cafodd hyn lawer o effeithiau ar brosesu wynebau ond yn benodol, gwelsom fod wynebau yn cael eu barnu i fod yn fwy deniadol pan fyddant wedi'u masgio. Deallir bod hyn oherwydd ein bod yn llenwi'r rhan goll o'r wyneb gyda fersiwn cyfartalog neu well na'r cyfartaledd o wyneb.

Y dyffryn anhygoel
Gellir gweld gwrthrychau sy'n edrych fel wynebau ond nad ydynt (wynebau doliau neu wynebau avatar) yn "anhygoel" wrth iddynt fynd yn fwy tebyg i fod yn debyg i fod yn debyg i ddynol. Mae hyn wedi cael ei alw'n ddyffryn anhygoel. Mae ein hymchwil wedi archwilio meysydd eraill sy'n dangos effeithiau dyffryn anhygoel tebyg. Rydym hefyd wedi archwilio ystod o ddamcaniaethau ar gyfer yr effaith hon ac wedi awgrymu ffyrdd newydd o ddychmygu'r dyffryn hwn.

Sifftiau cyclig yn hoffterau wyneb benywaidd
Mae ymchwil flaenorol wedi dangos bod dewisiadau menywod ar gyfer wynebau gwrywaidd yn newid dros y cylch mislif. Dangoswyd hyn gyda newidiadau mewn dewis cymesuredd a dewis gwrywdod. Mae fy ymchwil yn awgrymu y gallai'r canfyddiadau hyn fod yn arteffact o'r dulliau a ddefnyddir yn gyffredin yn y math hwn o ymchwil.

Wynebau hil gymysg
Yn aml, gall wynebau du i gyd edrych yr un fath i bobl wyn a gellir arsylwi ar yr effaith wrthdro i bobl wyn. Sut mae wynebau hil gymysg yn ffitio o fewn hyn? Mae wynebau hil gymysg yn cynnig ffyrdd diddorol o edrych ar sut mae hil yn cael ei gategoreiddio yn ôl ymddangosiad wyneb. Ymhellach, awgrymwyd hefyd bod prosesau genetig, fel egni hybrid, yn effeithio ar wynebau hil gymysg gan eu gwneud yn ymddangos yn fwy deniadol.

Botox a hwyliau
Mae gwenu yn gwneud i ni deimlo'n hapus tra bod frowning yn gwneud i ni deimlo'n drist. Ni all pobl sydd wedi cael denervation cemegol o'u cyhyrau frown (fel yn y driniaeth a elwir yn Botox) frown. Rydym wedi darganfod bod y bobl hyn (o bosibl oherwydd nad ydynt bellach yn gallu cael yr adborth o frowning) yn hapusach na phobl am gael mathau eraill o driniaeth gosmetig. Mae ymchwil gyfredol yn archwilio goblygiadau seicolegol posibl eraill o'r triniaethau cosmetig cynyddol gyffredin hyn.

Rhagfarn wrth brosesu wynebau
Gwelir rhagfarn mewn prosesu wynebau fel bod wynebau hiliol anghyfarwydd yn cael eu prosesu'n wahanol i wynebau hiliol cyfarwydd. Mae hyn hefyd yn cael ei arsylwi ar gyfer wynebau oedran neu rywiau gwahanol i'r arsyllwr. Mae fy ymchwil wedi anelu at ddeall y rhagfarnau hyn mewn prosesu wynebau.

Effeithiau Navon
Mae darllen llythrennau bach ffigwr mawr wedi'i wneud o lythrennau bach (ffigwr Navon) yn cael effeithiau annisgwyl. Mae'n gwneud pobl yn waeth mewn tasgau adnabod wynebau ond mae hefyd yn gwneud adnabod gwin yn anodd.
Mae fy ymchwil yn ceisio deall a chymhwyso'r ffenomenau hyn. Er enghraifft, gallai'r un prosesau sy'n achosi'r effaith Navon hwn hefyd esbonio pam mae pobl yn ddrwg am adnabod wynebau ar ôl iddynt fod yn gwneud croeseiriau cryptig.

Sut allwn ni weld celwyddog?
Pan fydd pobl yn dweud celwydd, a oes angen iddynt atal y gwir yn gyntaf? Os ydyn nhw'n gwneud hynny, allwn ni ddefnyddio'r amser ychwanegol a gymerir i wneud hyn i weithio allan a yw rhywun yn dweud celwydd? Mae ymchwil gyfredol yn edrych ar a yw'n cymryd mwy o amser i ddweud celwydd nag i ddweud y gwir. Rydym hefyd yn archwilio a yw rhai pobl yn arbennig o dda am ddatgelu celwyddau ac yn ceisio nodi pa arwyddion maen nhw'n eu defnyddio.

Canfod wynebau
Er bod llawer yn hysbys am ffactorau sy'n effeithio ar adnabod wynebau, cymharol ychydig sy'n cael ei wybod am ganfod wynebau - hynny yw'r gallu i weld wyneb mewn golygfa. Mae hyn yn syndod gan ei fod yn rhagofyniad i gydnabyddiaeth yn y byd naturiol. Modern technological devices (e.e. cameras) often come with face detection software but these are often fooled in ways that a human observer would not be. Mae fy ymchwil yn y maes hwn yn cynrychioli'r dadansoddiad systematig cyntaf o'r prosesau seicolegol o ganfod wynebau.

Dulliau ystadegol mewn seicoieithyddiaeth
Mae'r gair 'cat' yn cael ei ddarllen yn gyflymach na 'aardvark' ond a yw'r gwahaniaeth hwn oherwydd ei fod yn fyrrach, yn fwy aml, wedi'i ddysgu yn gynharach, mae ganddo eiriau mwy tebyg neu ddim ond mwy blewog? Mae hwn yn gwestiwn sydd wedi trethu seicolinghyddion am amser heb ddatrysiad. Y broblem gyda'r maes ymchwil hwn yw bod ymchwil arbrofol (hynny yw lle, er enghraifft, hyd y gair 'cath' yn cael ei drin ) yn amhosibl. Nod fy ymchwil oedd mynd i'r afael â'r mater hwn gan ddefnyddio modelu hafaliadau strwythurol – dull sy'n profi perthnasoedd achosol damcaniaethol rhwng amrywiaeth o newidynnau arsylwadol yn union fel y gallech ei ddefnyddio i weld a yw statws economaidd-gymdeithasol neu hil yn rhagweld perfformiad yn yr ysgol.

Modelau o adnabod wynebau
Rydym yn adnabod wynebau yn gyflym iawn, ond mae'r gwahaniaeth yn yr amser a gymerir i adnabod rhai wynebau yn caniatáu inni gynhyrchu modelau o sut mae'r wybodaeth yn cael ei storio. Mae wynebau nodweddiadol (neu gyfartalog) yn cael eu hadnabod yn arafach nag wynebau nodweddiadol. Gellir adnabod wyneb caricatured yn gyflymach na delwedd gywir o berson. Mae wynebau hiliau nad ydym yn gyfarwydd â nhw yn arafach i'w hadnabod. Fe wnes i ddatblygu a phrofi model o gof wyneb (o'r enw face-space-r) a oedd yn seiliedig ar ychydig o egwyddorion syml ond a allai esbonio ystod eang o batrymau yn y ffordd yr ydym yn adnabod wynebau.

Meysydd goruchwyliaeth
Faces are all very similar, yet we can distinguish among a large number of known faces and extract a wealth of information from them with remarkable speed and accuracy. My research explores this amazing ability from detecting a face in a visual scene, through recognition of a person, to retrieval of information concerning that person. I am also interested in the perception of emotional expressions, attractiveness and racial differences. While some experiments involve studying the learning of faces, other experiments explore facial illusions, caricatures, facial morphing or other visual manipulation of faces. Application of our understanding of face-related processes are important for studying dysfunctions of face recognition (eg, prosopagnosia, Capgras delusion) as well as within the forensic field.
If you are interested in applying for a PhD, or for further information regarding my postgraduate research, please contact me directly, or submit a formal application.
Current students
Scott Jones (Jointly supervised by Dominic Dwyer; funded by EPSRC). Scott is applying elements of perceptual learning in order to understand how faces move from being unfamiliar to familiar during learning. It is hoped that this understanding will lead to methods by which we can improve the learning of new faces.
Emma Williams (Jointly supervised by Lewis Bott; Funded by EADS). Emma is exploring the psychology of lying. She is investigating the cognitive effect of suppressing the truth when one lies. She is trying to identify whether some people are better at detecting lies and what cues they use to do this.
David Ross (Funded by ESRC). David is investigating the nature of our memory for faces. How are the many different faces that we can so quickly recognise stored?
