Mae cof llafar tymor byr (vSTM) yn cyfeirio at y gallu y mae gwybodaeth fel testun llafar neu ysgrifenedig yn cael ei storio ac, ar ôl oedi byr, ei adfer. Credir bod y gallu i storio ac adfer gwybodaeth dros dro yn sail i swyddogaethau gwybyddol beirniadol fel deall brawddegau a rhesymu/gwneud penderfyniadau. Felly, dylai deall vSTM arwain at well dealltwriaeth o wybyddiaeth yn fwy cyffredinol.

Mae gen i ddiddordeb mewn deall sut rydyn ni'n cofio (ac anghofio) gwybodaeth newydd ac wrth geisio deall y prosesau sy'n sail i hyn.

Research topics

Remembering information over the short-term is often explained by relying on the classical distinction between long-term memory and short-term memory with forgetting occurring due to processes operating within a short-term memory store such as interference or decay. Key phenomena such as the word-length effect, lexicality effect and the frequency effect are all used as evidence of a distinct short-term memory store and as evidence of the processes proposed to operate within it. My research considers that performance in verbal short-term memory (vSTM) tasks can instead be reinterpreted in terms of the use of more general perceptual and motor skills and that, rather than processes operating within a distinct short-term memory store, it is actually the opportunistic use of these skills that causes such short-term memory phenomena to emerge.

As an extension of this research, I am keen to bridge our knowledge of memory and cognition with cutting edge research into cyber security. Humans have typically been seen as the ‘weak-link’ when it comes to cyber-security with a tendency to view the improvement of cyber security as a matter of systems’ development. However, it is becoming increasingly evident that the human contribution to security is paramount and an area where cognitive psychology (in particular, short-term memory research methodology and theory) has begun making positive contributions. However, to best utilise human behaviour within a system, it is first important to understand how and why human behaviour manifests within cyberspace, before solutions to mitigate risks that incorporate human strengths are designed and implemented within organisations. As part of this research I have worked within The Cyber Lab contained within The Airbus Cyber Innovation Hub (a joint initiative between Airbus and Welsh Government to drive and deliver ground-breaking innovation in Wales). Contained within the Cyber Lab is a Human-Centric Cyber Security Team that explore areas such as identifying susceptibilities to certain security risks and designing strategies that enable individuals to become the best defence for future risks. Recent interest in the utilisation of vSTM tasks/theory in these areas has already led to a number of key findings and recommendations.

Addysgu

Rwy'n cyfrannu at gyflwyno ac addysgu modiwl Ffactorau Dynol y Flwyddyn Olaf (PS3119) ar y cwrs BSc Seicoleg. Rwyf hefyd yn goruchwylio prosiectau ymchwil y flwyddyn olaf ac yn cyflwyno tiwtorialau academaidd.

Ar lefel ôl-raddedig, rwy'n cyfrannu at addysgu ar y cwrs MSc Seicoleg.
