This paper defends a desire-based understanding of pleasurable and unpleasant experiences. More specifically, the thesis is that what makes an experience pleasant/unpleasant is the subject having a certain kind of desire about that experience. I begin by introducing the ‘Desire Account’ in more detail, and then go on to explain and refute a prominent set of contemporary counter-examples, based on subjects who might have ‘Reflective Blindness’, looking particularly at the example of subjects with depression. I aim to make the Desire (...) Account more persuasive, but also to clear up more widespread misunderstandings about depression in metaethics. For example, mistakes that are made by conflating two of depression’s most prominent symptoms: depressed mood and anhedonia. (shrink)

In this work, we evaluate the status of both theory and empirical evidence in the field of experimental rest-break research based on a framework that combines mental-chronometry and psychometric-measurement theory. To this end, we provide a taxonomy of rest breaks according to which empirical studies can be classified. Then, we evaluate the theorizing in both the basic and applied fields of research and explain how popular concepts relate to each other in contemporary theoretical debates. Here, we highlight differences between all (...) these models in the light of two symbolic categories, termed the resource-based and satiation-based model, including aspects related to the dynamics and the control mechanisms at work. Based on a critical assessment of existing methodological and theoretical approaches, we finally provide a set of guidelines for both theory building and future empirical approaches to the experimental study of rest breaks. We conclude that a psychometrically advanced and theoretically focused research of rest and recovery has the potential to finally provide a sound scientific basis to eventually mitigate the adverse effects of ever increasing task demands on performance and well-being in a multitasking world at work and leisure.

The brain's reliance on glucose as a primary fuel source is well established, but psychological models of cognitive processing that take energy supply into account remain uncommon. One exception is research on self-control depletion, where debate continues over a limited-resource model of self-control depletion. This model argues that transient reduction in self-control after exertion of prior self-control is caused by the depletion of brain glucose, and that self-control processes are special, perhaps unique, in this regard. This model has been argued (...) to be physiologically implausible in several recent reviews. This paper attempts to correct some inaccuracies that have occurred during debate over the physiological plausibility of this model. We contend that not only is such limitation of cognition by constraints on glucose supply plausible, it is well established in the neuroscience literature across several cognitive domains. Conversely, we argue that there is no evidence that self-control is special in regard to its metabolic cost. Mental processes require physical energy, and the body is limited in its ability to supply the brain with sufficient energy to fuel mental processes. This article reviews current findings in brain metabolism and seeks to resolve the current conflict in the field regarding the physiological plausibility of the self-control glucose-depletion hypothesis.
