Skin colour, pigmentation and the perceived health of human faces
(University of St Andrews, 2009-11-11) - Thesis,
Many non-human animal species use colour to signal dominance, condition or reproductive status. These signals have not previously been noted in humans. This thesis investigates the effects of skin colouration and pigmentation ...
Factors influencing the motivational salience of faces
(University of St Andrews, 2013) - Thesis,
My research utilizes a behavioral key-press task adapted from the classic bar-press technique employed in many rodent studies of reward to explore the incentive salience of beauty among humans. In Chapter 2, I replicate ...
Face evaluation : perceptual and neurophysiological responses to pro-social attributions
(University of St Andrews, 2013-06-25) - Thesis,
The pro-sociality of humans is manifested by the existence of cooperation in levels not common with any other species. Previous studies suggest that snap judgements of individuals are enough to determine if someone is a ...
Sexual selection and trust games
(University of St Andrews, 2010-06-23) - Thesis,
In economic games the facial attributes of counterparts bias decisions to trust and decisions to enter play. We report research supporting hypotheses that trust and reciprocation decisions in trust games are biased by ...
The effects of female status on sex differentiated mate preferences
(University of St Andrews, 2007) - Thesis,
Mate preferences provide an opportunity to explore the validity of evolutionary and social role origin theories of sex differences in human behaviour. In evolutionary models, preferences are sex-specific adaptive responses ...
Sexual selection and the human face : beauty in the face of the beheld and in the eye of the beholder
(University of St Andrews, 2004-06) - Thesis,
Evolutionary theory has been proposed to provide an answer to the question of why some faces are perceived to be more attractive than others are. The first part of this thesis provides an introduction to an evolutionary ...
The effects of pubertal timing and dominance on the mating strategy, appearance and behaviour of men
(University of St Andrews, 2008) - Thesis,
Pubertal timing is a human life history variable representing a trade-off between early reproduction and continued growth. Dominance is an important feature to male mate value. These two variables should have far-reaching ...

Visual processing in a primate temporal association cortex: insensitivity to self-induced motion
(University of St Andrews, 1993) - Thesis,
An animal's own behaviour can give rise to sensory stimulation that is very similar to stimulation of completely external origin. Much of this self-induced stimulation has little informative value to the animal and may ...
Linking 3D face shape to social perception
(University of St Andrews, 2015-09) - Thesis,
Advances in computer graphic and statistical methods have made it possible to visualise global face shape correlates of social judgments. The current thesis used a data-driven approach to investigate face shape correlates ...
