Ernest Sosa draws a distinction between animal knowledge and reflective knowledge, and this distinction forms the centerpiece
of his new book, A Virtue Epistemology. This paper argues that the distinction cannot do the work which Sosa assigns to it.

Helplessness, a belief that the world is not subject to behavioral control, has long been central to our understanding of depression, and has influenced cognitive theories, animal models and behavioral treatments. However, despite its importance, there is no fully accepted definition of helplessness or behavioral control in psychology or psychiatry, and the formal treatments in engineering appear to capture only limited aspects of the intuitive concepts. Here, we formalize controllability in terms of characteristics of prior distributions over affectively charged environments. We explore the relevance of this notion of control to reinforcement learning methods of optimising behavior in such environments and consider how apparently maladaptive beliefs can result from normative inference processes. These results are discussed with reference to depression and animal models thereof. 相似文献

Although traditional accounts of attachment theory attempted to partition the organism’s attachment and separation responses
into those that were instinctive and those that were the result of the developmental environment, recent findings from epigenetics
are indicating that no such partitioning is possible, even in principle. Rather than assuming the expression of a given behavioral
trait is based on some set of instincts (as Bowlby and many of his colleagues did for attachment and separation responses),
behavioral development is now seen as a self-organizing, probabilistic process in which pattern and order emerge and change
as a result of ongoing co-actions among developmentally relevant components both internal (e.g., genes, hormones, neural networks)
and external (e.g., temperature, diet, social interaction) to the organism. Exploring the specific prenatal and postnatal
features of the mother–infant interaction system is providing a new appreciation of the complexity of the origins and maintenance
of early attachment and its long-term consequences.

Beliefs serve at least two broad functions. First, they help us navigate the world. Second, they serve as signals to manipulate others. Philosophers and psychologists have focused on the first function while largely overlooking the second. This article advances a conception of signals and makes a prima facie case for a social signaling function for at least some beliefs. Truth and rational support are often irrelevant to the signaling function. If some beliefs evolved for a signaling function, then we should expect various biases that aid in the manipulation of others. 相似文献

As the number of instrtumental responses required to procure access to food is increased, animals decrease the frequency of initiating meals and increase meal size, conserving total intake while limiting the increase in the overall cost of feeding. In two studies, one using wheel turns and one using bar presses as the instrumental response, we asked whether freely feeding laboratory rats measure cost according to the energy or the time they expend. In each study we varied both the price (i.e., number of wheel turns or bar presses) and the force required to make a response (i.e., torque on the wheel or weight of the bar). Price affected both procurement time (from the first to the last procurement response) and procurement work, whereas torque and bar weight affected work without altering time in most cases. Meal patterns were altered by all manipulations of price, but changes in torque and bar weight had little effect on meal patterns, except in the conditions in which they altered procurement time. These results suggest that time is a critical currency of procurement cost in rats. 相似文献

This paper explores the significance of intelligent social behavior among non-human animals for philosophical theories of communication. Using the alarm call system of vervet monkeys as a case study, I argue that interpersonal communication (or what I call “minded communication”) can and does take place in the absence of the production and recognition of communicative intentions. More generally, I argue that evolutionary theory provides good reasons for maintaining that minded communication is both temporally and explanatorily prior to the use of communicative intentions. After developing these negative points about the place of communicative intentions in detail, I provide a novel alternative account according to which minded communication is characterized in terms of patterns of action and response that function to coordinate the representational mental states of agents. I show that an account which centers on patterns of representational coordination of this sort is well suited to capture the theoretical roles associated with minded communication and that it does so in a way that provides a good fit with comparative facts about the presence of minded communication among non-human animals. 相似文献

Despite the well-documented implications of right-wing ideological dispositions for human intergroup relations, surprisingly little is understood about the implications for human–animal relations. We investigate why right-wing ideologies – social dominance orientation (SDO) and right-wing authoritarianism (RWA) – positively predict attitudes toward animal exploitation and meat consumption. Two survey studies conducted in heterogeneous community samples (Study 1, N = 260; Study 2, N = 489) demonstrated that right-wing ideologies predict greater acceptance of animal exploitation and more meat consumption through two explaining mechanisms: (a) perceived threat from non-exploitive ideologies to the dominant carnist ideology (for both SDO and RWA) and (b) belief in human superiority over animals (for SDO). These findings hold after controlling for hedonistic pleasure from eating meat. Right-wing adherents do not simply consume more animals because they enjoy the taste of meat, but because doing so supports dominance ideologies and resistance to cultural change. Psychological parallels between human intergroup relations and human–animal relations are considered. 相似文献

Developmental differences in hypothalamic–pituitary–adrenal (HPA) axis responsiveness to stressors and ongoing development of glucocorticoid-sensitive brain regions in adolescence suggest that similar to the neonatal period of ontogeny, adolescence may also be a sensitive period for programming effects of stressors on the central nervous system. Although research on this period of life is scarce compared to early life and adulthood, the available research indicates that effects of stress exposure during adolescence differ from, and may be longer-lasting than, effects of the same stress exposure in adulthood. Research progress in animal models in this field is reviewed including HPA function and the enduring effects of stress exposures in adolescence on sensitivity to drugs of abuse, learning and memory, and emotional behaviour in adulthood. The effects of adolescent stress depend on a number of factors, including the age, gender, the duration of stress exposure, the type of stressor, and the time between stress exposure and testing. 相似文献
