    Action and experience

    The project examines the relationship between perception and action, and is divided into two parts. The first establishes a detailed philosophical critique of recent sensorimotor or enactive approaches to perception, targeting in particular the work of Alva Noë. In the second part I defend what may be called an 'action-space' account, according to which conscious experience is constituted by an agent's representing his surroundings in such a way as to enable a certain suite of actions. The enactive approach, I argue, misconstrues the relationship between perception and action and fails in its aim to provide an explanation of consciousness. It faces difficulties, too, when it comes to illusion, hallucination and non-visual perception. The action-space model, by contrast, drawing upon work by Andy Clark, Daniel Dennett and Philip Pettit, has the resources to provide a reductive, functionalist account of phenomenal consciousness; an account that locates consciousness where we want it - in the service of fluid world-engagement by embodied, active perceivers. Thus the perception/action interface is taken to be less direct than on the sensorimotor interpretation, but is nonetheless deep and important. The approach I endorse, furthermore, is consistent with and informed by empirical results from the cognitive sciences, including work on embodied, situated cognition and dual-streams analyses of visual processing

    Aesthetic Pleasure from Visual Quotes and its Influence on Individuals' Motivation to Exercise

    It is well-known that physical activity has many benefits for health and well-being. However, one in four adults worldwide does not engage in enough physical activity. On the other hand, nowadays, many people look for physical exercise motivation online on image-sharing social media platforms, where it is relatively common to find encouraging text messages embedded in visual presentations (as visual quotes). Considering that perceived beauty can influence our perception of an artifact, this research project explored whether and how aesthetic pleasure affects people's perception of motivational text messages and the textual content's motivating capability on people's exercise motivation. The influence of several aesthetic pleasure levels (ugly, neutral, and beautiful) was explored in textual content with different characteristics (e.g., positive-framed, self-liberating messages, low-perceived competence, high-perceived competence). Several experiments revealed that high levels of aesthetic pleasure does not necessarily lead individuals to perceive a textual message as more positive. Similarly, low levels of aesthetic pleasure did not affect textual content perception. Indeed, ultimately, the influence of aesthetic pleasure seemed dependent on the textual content's own characteristics. Some experiments focused on the immediate effect of aesthetic pleasure, while others focused on aesthetic pleasure in the mid-term (over four weeks). In none of the scenarios did aesthetic pleasure influence intrinsic motivation, which has been found to be linked to individuals’ enjoyment of and likelihood of engagement with exercise over the long-term, or influence the extrinsic motivation (the identified behavior regulation), related to the initial adoption of physical exercise. Nonetheless, it was found that visual presentations perceived as aesthetically appealing help to instill a positive feeling regarding the textual content. Possibilities for future research are suggested on the basis of Cognitive Evaluation Theory, a sub-theory of Self-Determination Theory).É de conhecimento geral que fazer exercício físico traz vários benefícios para a saúde e bem-estar. Contudo, um em quatro adultos em todo o mundo não faz exercício físico suficiente. Por outro lado, hoje em dia, muitas pessoas procuram motivação para fazer exercício físico na internet nas redes sociais, onde facilmente se podem encontrar mensagens de texto motivacionais embutidas em apresentações visuais (designadas visual quotes). Tendo em conta que a perceção de prazer estético pode influenciar a nossa perceção sobre um determinado artefacto ou pessoa. Este projeto de investigação explorou se e como o prazer estético pode afetar a perceção de mensagens motivacionais e a capacidade motivadora do conteúdo textual na motivação das pessoas para fazer exercício físico.Foram explorados a influência de diversos níveis de prazer estético (feio, neutro, belo) em conteúdo textual com diferentes características (por exemplo, positive-framed, self-liberating, perceção de baixa-competência, perceção de alta-competência). Vários estudos (experiments) revelaram que níveis de perceção de prazer estético altos não levam necessariamente a que as pessoas percecionem as mensagens de texto como mais positivas. De forma similar, níveis de perceção de prazer estético baixos não afetaram a perceção do conteúdo textual. Em último caso, a influência da perceção de prazer estético pareceu dependente das próprias características do conteúdo textual. Alguns dos estudos focaram-se no efeito imediato da perceção de prazer estético enquanto outros focarem-se no efeito a curto prazo (até quatro semanas). Em nenhum dos cenários, a perceção de prazer estético influenciou a motivação intrínseca para fazer exercício físico dos participantes, que está associada à prática de fazer exercício físico a longo-prazo; Ou influenciou a motivação extrínseca identified behavior regulation, que está associada à adoção inicial de hábitos de exercício físico. Não obstante, verificou-se que as apresentações visuais das visual quotes percecionadas como esteticamente apelativas ajudam a incutir um “sentimento” positivo relativo ao conteúdo textual. Por último, são sugeridas possibilidades para futura investigação tendo como base a teoria Cognitive Evalution (uma sub-teoria da teoria da Auto-determinação)

    Detecting cow behaviours associated with parturition using computer vision

    Monitoring of dairy cows and their calf during parturition is essential in determining if there are any associated problems for mother and offspring. This is a critical period in the productive life of the mother and offspring. A difficult and assisted calving can impact on the subsequent milk production, health and fertility of a cow, and its potential survival. Furthermore, an alert to the need for any assistance would enhance animal and stockperson wellbeing. Manual monitoring of animal behaviour from images has been used for decades, but is very labour intensive. Recent technological advances in the field of Computer Vision based on the technique of Deep Learning have emerged, which now makes automated monitoring of surveillance video feeds feasible. The benefits of using image analysis compared to other monitoring systems is that image analysis relies upon neither transponder attachments, nor invasive tools and may provide more information at a relatively low cost. Image analysis can also detect and track the calf, which is not possible using other monitoring methods. Using cameras to monitor animals is commonly used, however, automated detection of behaviours is new especially for livestock. Using the latest state-of-the-art techniques in Computer Vision, and in particular the ground-breaking technique of Deep Learning, this thesis develops a vision-based model to detect the progress of parturition in dairy cows. A large-scale dataset of cow behaviour annotations was created, which included over 46 individual cow calvings and is approximately 690 hours of video footage with over 2.5k of video clips, each between 3-10 seconds. The model was trained on seven different behaviours, which included standing, walking, shuffle, lying, eating, drinking, and contractions while lying. The developed network correctly classified the seven behaviours with an accuracy of between 80 to 95%. The accuracy in predicting contractions while lying down was 83%, which in itself can be an early warning calving alert, as all cows start contractions one to two hours before giving birth. The performance of the model developed was also comparable to methods for human action classification using the Kinetics dataset
