Orientation dependence of spatial memory acquired from auditory experience

The present study investigated whether memory for a room-sized spatial layout learned through auditory localization of sounds exhibits orientation dependence similar to that observed for spatial memory acquired from stationary viewing of the environment. Participants learned spatial layouts by viewing objects or localizing sounds and then performed judgments of relative direction among remembered locations. The results showed that direction judgments following auditory learning were performed most accurately at a particular orientation in the same way as were those following visual learning, indicating that auditorily encoded spatial memory is orientation dependent. In combination with previous findings that spatial memories derived from haptic and proprioceptive experiences are also orientation dependent, the present finding suggests that orientation dependence is a general functional property of human spatial memory independent of learning modality.     

Longitudinal associations between hostility in adolescents' family relationships and friendships and hostility in their romantic relationships.

This study examined longitudinal predictors of hostility in adolescents' romantic relationships. The sample included 110 adolescents and their parents from 72 families. Observational measures of parents' marital hostility and parent-child hostility and self-reports of hostility in close friendships were collected when adolescents ranged from 14 to 16 years old. Three years later, when they were 17 to 19 years old, adolescents reported on the hostility in their romantic relationships. Results indicated that hostility in parents' marital relationships and in adolescents' friendships accounted for independent variance in hostility in adolescents' later romantic relationships. Results highlight the importance of both family relationships and friendships for predicting hostility in adolescents' romantic relationships over time.     

Li Zehou and Moritz Schlick on the Roots of Beauty

Beginning from the Enlightenment view that beauty or art is ＂useless,＂ the attempts to explain how aesthetic experience and judgment are possible presented by Moritz Schlick and Li Zehou are examined, compared and contrasted. The paper treats three main subjects, the anthropological origins of beauty, the origins of aesthetic judgments and the problem of the purpose or function of beauty or aesthetic experience. In the first--the historical-causal roots of beauty--the problem discussed is how to account for aesthetics in light of the practical needs and pursuits of human beings. For Schlick, the problem is couched in terms of how aesthetic experience can be made consistent with natural selection. The second main subject-the philosophical roots of beauty-is a discussion of the origin in the sense of justification of aesthetic judgments. And the third examines the problem of assigning some purpose to aesthetic feelings and attitudes. An apparent contrast is made, and perhaps resolved, between the respective views of Schlick and Li.     

A systematic review of cognitive functioning among young people who have experienced homelessness,foster care,or poverty

Young people who have experienced homelessness, foster care, or poverty are among the most disadvantaged in society. This review examines whether young people who have these experiences differ from their non-disadvantaged peers with respect to their cognitive skills and abilities, and whether cognitive profiles differ between these three groups. Three electronic databases were systematically searched for articles published between 1 January 1995 and 1 February 2015 on cognitive functioning among young people aged 15 to 24 years who have experienced homelessness, foster care, or poverty. Articles were screened using pre-determined inclusion criteria, then the data were extracted, and its quality assessed. A total of 31 studies were included. Compared to non-disadvantaged youth or published norms, cognitive performance was generally found to be impaired in young people who had experienced homelessness, foster care, or poverty. A common area of difficulty across all groups is working memory. General cognitive functioning, attention, and executive function deficits are shared by the homeless and poverty groups. Creativity emerges as a potential strength for homeless young people. The cognitive functioning of young people with experiences of impermanent housing and poverty has been relatively neglected and more research is needed to further establish cognitive profiles and replicate the findings reviewed here. As some aspects of cognitive functioning may show improvement with training, these could represent a target for intervention.     

Animal Activists,Civil Disobedience and Global Responses to Transnational Injustice

Traditionally, acts of civil disobedience are understood as a mechanism by which citizens may express dissatisfaction with a law of their country. That expression will typically be morally motivated, non-violent and aimed at changing their government’s policy, practice or law. Building on existing work, in this paper we explore the limits of one well-received definition of civil disobedience by considering the challenging case of the actions of animal activists at sea. Drawing on original interviews with advocates associated with Sea Shepherd, Greenpeace and Humane Society International we find that even if animal activists are morally motivated and civil, the transnational nature of their activity makes it difficult to assess their intention to bring about a change in law or public policy. This means that a civil disobedience defence may not be available to activists operating across international borders. This raises important questions about the usefulness of the civil disobedience concept within the context of a globalised world. We conclude that while the actions of some anti-whaling activists may not meet definitions of civil disobedience as conventionally understood, this says more about the narrow way in which that concept has been traditionally defined, than it does about the type of activity some anti-whaling activists have undertaken in the Southern Ocean. Finally, we argue that activists wishing to make a stand against whaling may have no choice but to act as global citizens because policy change within a single nation-state is unlikely to lead to the cessation of this inherently transnational activity.     

What Is Wrong with External Reasons?

In this paper I argue that only a subset of the reason statementsWilliams defines as external must be rejected as false. `A has areason to ' is necessarily false when the ends and aimsconstitutive of A's good close off the deliberative route from her S to the conclusion she has reason to . But when less important ends are at stake, it seems that a person's needs generally provide reasons for action, contrary to Williams's internalist account. I suspect, however, that there may remain inexorable disagreementover these claims because people value things in two distinct ways. Tosupport my suspicion, I explain how people's valuation can take either an agency-prioritizing or an end-prioritizing form. I then argue thatresolving the disagreement over Williams's internalist account ofreasons depends on whether it can be established that the agency-prioritizingform is the rationally superior form of valuation.     

11Beta-hydroxysteroid dehydrogenase type 1 activity in medial vestibular nucleus and cerebellum after unilateral vestibular deafferentation in the rat

In the early stages of vestibular compensation (VC) (the behavioural recovery that follows unilateral vestibular deafferentation), neurons in the medial vestibular nucleus (MVN) on the lesioned side develop a sustained up-regulation of their intrinsic excitability. This plasticity is dependent on the activation of glucocorticoid receptors, which presumably occurs during the acute stress response that accompanies the vestibular deafferentation symptoms. Recent studies have established that the access of glucocorticoids to their intracellular receptors in brain is potently modulated by 11beta-hydroxysteroid dehydrogenase type 1 (11beta-HSD1), which catalyses the generation of active glucocorticoids from their inert 11-keto forms. In this study, we investigated the presence of 11beta-HSD1 bioactivity, and possible changes in activity in the early stage after vestibular deafferentation, in the cerebellar nodulus and uvula, the flocculus/paraflocculus (F/PF) complex and the MVN of the rat. 11beta-HSD1 activity was found in each of these brain areas, with especially high levels of activity in the F/PF complex. No differences were found in the level of 11beta-HSD1 activity in these brain areas between control rats, sham-operated rats and rats that underwent VC for 4 h after unilateral vestibular deafferentation. These findings demonstrate 11beta-HSD1 bioactivity in the MVN and vestibulocerebellum, but exclude the possibility that changes in 11beta-HSD1 activity occur in the early period after deafferentation, over the time when changes in MVN neuronal properties take place.     

The role of structural prediction in rapid syntactic analysis

A number of recent electrophysiological studies of sentence processing have shown that a subclass of syntactic violations elicits very rapid ERP responses, occurring within around 200 ms of the onset of the violation. Such findings raise the question of how it is possible to diagnose violations so quickly. This paper suggests that very rapid diagnosis of errors is possible specifically in situations where the diagnosis problem is tightly constrained by specific expectations generated before the critical word is presented. In an event-related potentials (ERP) study of visual sentence reading participants encountered violations of a word order constraint (...Max's of...) that has elicited early ERP responses in previous studies. Across conditions the illicit sequence was held constant, while sentence context was used to manipulate the expectation for a noun following the possessor Max's, by manipulating the possibility of ellipsis of the head noun. Results showed that the anterior negativity elicited by the word category violation was attenuated when the availability of ellipsis reduced the expectation for a noun in the position of the offending preposition of, with divergence between conditions starting around 200 ms after the onset of the violation. This suggests a role for structural expectations in accounting for very fast syntactic diagnosis processes.
