Enhancing Training Efficiency and Effectiveness Through the Use of Dyad Training

The authors examined the effect of inserting observation practice and undirected dialog into the rest interval between practice trials on the learning of a complex task (stabilometer). Training protocols in which learners practice in pairs (dyads) result in increases in learning efficiency, but the critical issue is the effect on learning effectiveness. Three groups of participants (n = 12 in each group) practiced maintaining their balance on a stabilometer. One group practiced individually, and the other 2 groups practiced in dyads in which 1 performer practiced the task while the other observed. In the dyad-alternate condition, participants alternated between physical, observational, and dialog practice on each trial, whereas in the dyad-control condition, subjects completed all trials on 1 form of practice (either physical or observational practice) before engaging in the other form. The results indicated that the dyad-alternate group initially performed more poorly but quickly overtook the individual group, and the performance advantage of the dyad-alternate group was maintained on the delayed retention test. When the different forms of practice were performed consecutively, as in the dyad-control group, acquisition and retention performance was generally poorer than when they were alternated. Those results suggest that one can combine the benefits of physical practice, observation, and dialog between learners in an interactive way to produce an effective and efficient learning protocol.     

Kant's Synthetic and Analytic Method in the Critique of Pure Reason and the Distinction between Philosophical and Mathematical Syntheses

This article addresses Kant's distinction between a synthetic and an analytic method in philosophy. I will first consider how some commentators have accounted for Kant's distinction and analyze some passages in which Kant defined the analytic and the synthetic method. I will suggest that confusion about Kant's distinction arises because he uses it in at least two different senses. I will then identify a specific way in which Kant accounts for this distinction when he is differentiating between mathematical and philosophical syntheses. I will examine Kant's arguments in the Critique of Pure Reason with the latter sense of the distinction in mind. I will evaluate if he uses the analytic or the synthetic method and if the synthetic method is able to identify, without a previous consideration of some sort of given knowledge, sufficient conditions for deriving some aspects of our knowledge.     

Goal projection in public places

Three studies investigated the phenomenon of goal projection in everyday life considering three moderators: goal commitment, the perceived similarity of the target person, and goal attainment. Moviegoers' (Study 1) highly committed to see a particular movie projected this goal onto other movie patrons. Commuters (Study 2) highly committed to catch a certain train projected this goal onto other commuters, given that these commuters were perceived as similar. Shoppers (Study 3) projected buying a particular item when both their goal commitment and the perceived similarity of another shopper were high, and the goal was not yet attained. The results imply that goal projection is part of our everyday life and is fostered by high‐goal commitment, perceiving others as similar, and ongoing goal striving.     

Visual Feeling of Presence

Everyday visual experience constantly confronts us with things we can interact with in the real world. We literally feel the outside presence of physical objects in our environment via visual perceptual experience. The visual feeling of presence is a crucial feature of vision that is largely unexplored in the philosophy of perception, and poorly debated in vision neuroscience. The aim of this article is to investigate the feeling of presence. I suggest that visual feeling of presence depends on the visual representation of a very particular spatial relation with the object we interact with: the visual representation of absolute egocentric depth, which is due to stereoscopic vision.     

The role of encoding strategies in the verbal memory performance in patients with schizophrenia

Background. Verbal learning and memory is often compromised in patients with schizophrenia who prefer encoding words in order of their presentation (serial clustering) rather than using semantic categories (semantic clustering). Method. One hundred and four in‐patients with schizophrenia were assessed twice with the California Verbal Learning Test. Results. Patients showed significantly less semantic than serial clustering at both assessment times. Usage of encoding strategies were not stable over time. An increase in semantic clustering improved recall and recognition performance. Conclusions. Patients with schizophrenia should be taught to use the more effective encoding strategy of semantic clustering in order to improve their memory performance.     

Memory for object location and route direction in virtual large-scale space

In everyday life people have to deal with tasks such as finding a novel path to a certain goal location, finding one's way back, finding a short cut, or making a detour. In all of these tasks people acquire route knowledge. For finding the same way back they have to remember locations of objects like buildings and additionally direction changes. In three experiments using recognition tasks as well as conscious and unconscious spatial priming paradigms memory processes underlying wayfinding behaviour were investigated. Participants learned a route through a virtual environment with objects either placed at intersections (i.e., decision points) where another route could be chosen or placed along the route (non-decision points). Analyses indicate first that objects placed at decision points are recognized faster than other objects. Second, they indicate that the direction in which a route is travelled is represented only at locations that are relevant for wayfinding (e.g., decision points). The results point out the efficient way in which memory for object location and memory for route direction interact.     

Towards a Semantics Based on the Notion of Justification

Suppose we want to take seriously the neoverificationist idea that an intuitionistic theory of meaning can be generalized in such a way as to be applicable not only to mathematical but also to empirical sentences. The paper explores some consequences of this attitude and takes some steps towards the realization of this program. The general idea is to develop a meaning theory, and consequently a formal semantics, based on the idea that knowing the meaning of a sentence is tantamount to having a criterion for establishing what is a justification for it. Section 1 motivates a requirement of epistemic transparency imposed onto justifications conceived as mental states. In Section 2, the formal notion of justification for an atomic formula is defined, in terms of the notion of cognitive state. In Section 3, the definition is extended to logically complex formulas. In Section 4, the notion of truth-ground is introduced and is used to give a definition of logical validity.     

Quality of life in patients before and after kidney transplantation

Abstract

The aim of the present study was to differentially determine quality of life (QOL) in patients with end-stage renal disease (ESRD) after successful kidney transplantation (RT, Group A) compared with ESRD patients on a waiting list for RT (Group B). and with healthy controls (Group C) because opinions vary as to which treatment modality can best assure ESRD patients a high QOL.

Groups A, B and C each consisted of 149 persons, matched for age and gender. The Munich Quality of Life Dimensions List (MLDL) was used to measure global aspects of QOL. Distinct aspects of QOL were investigated by the Brief Symptom Inventory (BSI) and the Questionnaire for Social Support (K-22).

Groups A and C reported similar QOL. Which was significantly higher than in group B (p < .0001). This was particularly true for the physical and psychological status and daily activities, but not for the social situation. Groups A and B reported similar social support, which was significantly, lower than in group C (p < 006). Both ESRD groups reported higher satisfaction with social support than healthy controls (p < .0001).

Successful RT nor only improved distinct aspects of QOL in patients with ESRD, but even put them on par with healthy controls regarding physical and psychological QOL.

Lower social support and higher satisfaction with social support in both groups of ESRD patients should be evaluated further. From a clinical viewpoint. the improvement of physical and psychological aspects of QOL in RT patients is impressive; but more attention should be paid to constantly low social support in this group of patients. International multi center longitudinal studies to investigate QOL in ESRD patients under different treatments am necessary.     

Dispositions and interferences

In this paper I argue that olfactory experience, like visual experience, is exteroceptive: it seems to one that odours, when one smells them, are external to the body, as it seems to one that objects are external to the body when one sees them. Where the sense of smell has been discussed by philosophers, it has often been supposed to be non-exteroceptive. The strangeness of this philosophical orthodoxy makes it natural to ask what would lead to its widespread acceptance. I argue that philosophers have been misled by a visuocentric model of what exteroceptivity involves. Since olfaction lacks the spatial features that make vision exteroceptive the conclusion that olfaction is nonexteroceptive can appear quite compelling, particularly in the absence of an alternative model of exteroceptivity appropriate to olfaction. I offer a model according to which odours seem to be external to the body because they seem to be brought into the nose from without by sniffing and breathing through the nostrils. I argue that some natural-seeming objections to this model rely on substantive assumptions about how the senses are distinguished from one another, and how perceptual experience is put together out of its modality-specific parts, that require defence.
