Finger-digit compatibility in Arabic numeral processing

Finger-digit response compatibility was tested by asking participants to identify Arabic digits by pressing 1 of 10 keys with all 10 fingers. The direction of the finger-digit mapping was varied by manipulating the global direction of the hand-digit mapping as well as the direction of the finger-digit mapping within each hand (in each case, from small to large digits, or the reverse). The hypothesis of a left-to-right mental number line predicted that a complete left-to-right mapping should be easier whereas the hypothesis of a representation based on finger counting predicted that a counting-congruent mapping should be easier. The results show that when all 10 fingers are used to answer, a mapping congruent with the prototypical finger-counting strategy reported by the participants leads to better performance than does a mapping congruent with a left-to-right oriented mental number line, both in palm-down and palm-up postures of the hands, and they demonstrate that finger-counting strategies influence the way that numerical information is mentally represented and processed.     

Gadamer and the Otherness of Nature: Elements for an Environmental Education

In this work I search for elements that contribute to the development of the ethical dimension of environmental education. I start with the existence of what C.A. Bowers calls “areas of silence” in the curriculum in both schools and universities. The reason for this silence, I argue, is to be found in the Cartesian conceptual structures of curricula. I suggest that the works of Bacon, Galileo and Descartes provoke a twofold process that I have termed the forgetting of tradition and objectification of nature. As a corrective to this process, I explore the possibilities that the philosophical hermeneutics of Hans-Georg Gadamer opens for rehabilitation of tradition and de-objectification of nature. I work with the concept of the “dignity of things” present in Greek dialectics: that nature is not simply a projection of mind (as the neo-Kantians claim), but something that thought suffers. In my conclusions I argue that for nature to be reinserted into almost all areas of knowledge it is necessary that we respect “the otherness of nature.”     

Time-dependent effects of treadmill exercise on aversive memory and cyclooxygenase pathway function

Exercise induces brain function adaptations and improves learning and memory; however the time window of exercise effects has been poorly investigated. Studies demonstrate an important role for cyclooxygenase-2 (COX-2) pathway function in the mechanisms underlying memory formation. The aim of present work was to investigate the effects of treadmill exercise on aversive memory and COX-2, PGE(2) and E-prostanoid receptors contents in the rat hippocampus at different time points after exercise has ended. Adult male Wistar rats were assigned to non-exercised (sedentary) and exercised (running daily for 20min, for 2weeks) groups. The inhibitory avoidance task was used to assess aversive memory and the COX-2, PGE(2) and E-prostanoid receptors (EP1, EP2, EP3 and EP4) levels were determined 1h, 18h, 3days or 7days after the last training session of treadmill exercise. The step down latency in the inhibitory avoidance, COX-2 and EP4 receptors levels were acutely increased by exercise, with a significant positive correlation between aversive memory performance and COX-2 levels. Increased EP2 content decreased PGE(2) levels were observed 7days after the last running session. The treadmill exercise protocol facilitates inhibitory avoidance memory and induces time-dependent changes on COX-2 pathways function (COX-2, PGE(2) and EP receptors).     

rTMS stimulation on left DLPFC increases the correct recognition of memories for emotional target and distractor words

According to a recent hypothesis, the prefrontal cortex has been proposed as the site of emotional memory integration, because it is sensitive to the recognition of emotional contents. In the present research, we explored the role of the dorsolateral prefrontal cortex (DLPFC) in memory recognition processes for positive versus negative emotional stimuli when old (target) and new (distractor, either semantically related or unrelated to the target) stimuli were presented. The role of the DLPFC was analysed using an rTMS (repeated transcranial magnetic stimulation) paradigm that induced increased cortical activation of the left DLPFC. The subjects were required to perform a task that consisted of two experimental phases (i.e., an encoding and a recognition phase) in which the targets and the distractors were presented and recognition performance was measured. rTMS stimulation was provided over the left DLPFC during the recognition phase. We found that the rTMS stimulation affected the memory recognition of positive emotional material. Moreover, related and unrelated distractors were discarded better when they were positively valenced, and a more significant effect (i.e., increased performance) was produced in response to related distractors. This result suggests that the activation of the left DLPFC favours the memory recognition of positive emotional information, and that such activation is able to induce a more appropriate selective process to distinguish target from distractor stimuli in the presence of more complex processes (related distractors). The valence model of emotional cue processing may explain this increased performance by demonstrating the distinct role of the left hemisphere in the retrieval of positive emotional information.     

Animal Disenhancement for Animal Welfare: The Apparent Philosophical Conundrums and the Real Exploitation of Animals. A Response to Thompson and Palmer

In his paper “The Opposite of Human Enhancement: Nanotechnology and the Blind Chicken problem” (Nanoethics 2: 305-36, 2008) Thompson argued that technological attempts to reduce or eliminate selected non-human animals’ capabilities (animal disenhancements) in order to solve or mitigate animal welfare problems in animals’ use pose a philosophical conundrum, because there is a contradiction between rational arguments in favor of these technological interventions and intuitions against them. In her response “Animal Disenhancement and the Non-Identity Problem: A Response to Thompson” (Nanoethics 5:43–48, 2011), Palmer maintained that the philosophical conundrum is even deeper if we introduce the non-identity problem into the discussion. In my brief response, I claim that in order to avoid the pitfalls of speculative ethics, empirical facts related to the technologies involved as well as costs for the non-human animals have to be taken into account. Depending on which changes we are referring to, ethical problems can be seen very differently. Widening the consideration to the socio-economic context in which non-human animals are currently used by humans, I challenge the idea of genuine philosophical conundrums from an antispeciesist and abolitionist perspective. Only in a context of exploitation, in which non-human animals are deprived of basic rights and their existence is totally dependent on human exploitation, the contradictions between improvement of welfare and disenhancement of capabilities make sense.     

Diagnosenübergreifende Psychoedukation: ?Notbehelf“ oder ?Mittel der Wahl“?

Despite evidence for its efficacy, diagnosis-specific psychoeducation is not routinely applied because the patient numbers per diagnosis are often too low. In an exploratory randomized and controlled trial the efficacy of a bifocal diagnosis-independent group program was tested on inpatients of the Psychiatric Hospital of the University of Basel (N?=?82) regarding clinical variables, readmission and compliance as well as course-relevant subjective attitudes over a follow-up period of 12 months by means of quantitative as well as qualitative methods. Significant group differences were found regarding compliance at 3 months and the suicide rate, both in favour of the intervention group. For most other outcome variables clear advantages for psychoeducation could be shown. A first analysis of qualitative data revealed a more favourable development in the psychoeducation group, which was statistically significant. The to date sole findings on diagnosis-independent psychoeduation justify its clinical application and further investigation.     

Gender Hierarchy in the Space: The Role of Gender Status in Shaping the Spatial Agency Bias

According to the Spatial Agency Bias (SAB), more agentic groups (men) are envisioned to the left of less agentic groups (women). This research investigated the role of social status in shaping the spatial representation of gender couples. Participants were presented pairs consisting of one male and one female target who confirmed gender stereotypes. The status of the targets in each pair was systematically varied (high-status vs. low-status job). Participants chose the target order (female/male vs. male/female) they preferred. In line with gender-status expectations (male: high-status, female: low-status), a male in a high-status job led to a spatial arrangement that favored the male/female order, regardless of the status of the female target. The female/male order was favored only when the female had a high-status job and the male a low-status job. No SAB occurred for pairs in which both targets displayed low-status jobs. The implications of status for the SAB are discussed.
