On starting to think about interaction design for low-functioning persons in the autistic spectrum (PAS), especially children, one finds a number of questions that are difficult to answer: Can we typify the PAS user? Can we engage the user in interactive communication without generating frustrating or obsessive situations? What sort of visual stimuli can we provide? Will they prefer representational or abstract visual stimuli? Will they understand three-dimensional (3D) graphic representation? What sort of interfaces will they accept? Can we set ambitious goals such as education or therapy? Unfortunately, most of these questions have no answer yet. Hence, we decided to set an apparently simple goal: to design a "fun application," with no intention to reach the level of education or therapy. The goal was to be attained by giving the users a sense of agency--by providing first a sense of control in the interaction dialogue. Our approach to visual stimuli design has been based on the use of geometric, abstract, two-dimensional (2D), real-time computer graphics in a full-body, non-invasive, interactive space. The results obtained within the European-funded project MultiSensory Environment Design for an Interface between Autistic and Typical Expressiveness (MEDIATE) have been extremely encouraging. 相似文献

Many social phenomena involve a set of dyadic relations among agents whose actions may be dependent. Although individualistic
approaches have frequently been applied to analyze social processes, these are not generally concerned with dyadic relations,
nor do they deal with dependency. This article describes a mathematical procedure for analyzing dyadic interactions in a social
system. The proposed method consists mainly of decomposing asymmetric data into their symmetric and skew-symmetric parts.
A quantification of skew symmetry for a social system can be obtained by dividing the norm of the skew-symmetric matrix by
the norm of the asymmetric matrix. This calculation makes available to researchers a quantity related to the amount of dyadic
reciprocity. With regard to agents, the procedure enables researchers to identify those whose behavior is asymmetric with
respect to all agents. It is also possible to derive symmetric measurements among agents and to use multivariate statistical
techniques. 相似文献

We investigated the role of extraretinal information in the perception of absolute distance. In a computer-simulated environment, monocular observers judged the distance of objects positioned at different locations in depth while performing frontoparallel movements of the head. The objects were spheres covered with random dots subtending three different visual angles. Observers viewed the objects ateye level, either in isolation or superimposed on a ground floor. The distance and size of the spheres were covaried to suppress relative size information. Hence, the main cues to distance were the motion parallax and the extraretinal signals. In three experiments, we found evidence that (1) perceived distance is correlated with simulated distance in terms of precision and accuracy, (2) the accuracy in the distance estimate is slightly improved by the presence of a ground-floor surface, (3) the perceived distance is not altered significantly when the visual field size increases, and (4) the absolute distance is estimated correctly during self-motion. Conversely, stationary subjects failed to report absolute distance when they passively observed a moving object producing the same retinal stimulation, unless they could rely on knowledge of the three-dimensional movements. 相似文献

Executive control in the Simon effect: an electromyographic and distributional analysis 总被引:3,自引:0,他引:3
Manual responses to lateralized stimuli are faster for spatially congruent stimulus-response associations than for incongruent associations, even if the stimulus location is irrelevant. This effect, however, decreases as reaction time increases. Recent data suggest that such a decrease reflects online, within-trial executive control. The present study was aimed at testing this hypothesis by analyzing the electromyographic activity of muscles involved in response execution. We focused on the particular trials in which an activation of the muscle involved to the incorrect response preceded the execution of the correct response. A sequential effect analysis, along with an analysis of the reaction time distributions, revealed that after such dual-activation trials, executive control was reinforced. In addition, a distribution analysis of the reaction times associated with such trials compared to the trials without incorrect activation, revealed online, within-trial changes in executive control. Arguments against a late motor locus of the effect of the irrelevant stimulus location are also provided. These results are discussed in terms of current models of cognitive control. 相似文献

Several studies have established that humans orient their visual attention reflexively in response to social cues such as
the direction of someone else’s gaze. However, the consequences of this kind of orienting have been addressed only for the
visual system. We investigated whether visual social attention cues can induce shifts in tactile attention by combining a
central noninformative eye-gaze cue with tactile targets presented to participants’ fingertips. Data from speeded detection,
speeded discrimination, and signal detection tasks converged on the same conclusion: Eye-gaze-based orienting facilitates
the processing of tactile targets at the location of the gazed-at body location. In addition, we examined the effects of other
directional cues, such as conventional arrows, and found that they can be equally effective. This is the first demonstration
that social attention cues have consequences that reach beyond their own sensory modality. 相似文献

This paper starts from the presupposition that moral codes often do not suffice to make agents understand their moral responsibility.
We will illustrate this statement with a concrete example of engineers who design a truck’s trailer and who do not think traffic
safety is part of their responsibility. This opinion clashes with a common supposition that designers in fact should do all
that is in their power to ensure safety in traffic. In our opinion this shows the need for a moral philosophy that helps engineers
to interpret their responsibility and think more critically about it. For this purpose we will explore the moral philosophy
of Alasdair MacIntyre, which is particularly interesting because he locates the beginning of moral thinking in the daily practice
of a profession. This is consistent with the history of moral codes, for codes are also the product of moral reflection by
professionals. We will use MacIntyre’s philosophy to (1) explain what is wrong with the designers’ understanding of their
responsibility and (2) show a possible way to bring their reflection to a more self-critical level. We will also inspect MacIntyre’s
proposal critically. 相似文献

The role of spatial attention and other processes on the magnitude and time course of cueing effects
We are quite often exposed to multiple objects present in the visual scene, thus attentional selection is necessary in order
to selectively respond to the relevant information. Objects can be selected on the basis of the location they occupy by orienting
attention in space. In this paper, we review the evidence showing that attention can be oriented in space either endogenously,
on the basis of central cues, predictive of the relevant location, or exogenously, automatically triggered by the salient
properties of visual stimuli (peripheral cues). Several dissociations observed between orienting on the basis of the two types
of cues have led to the conclusion that they do not represent just two modes of triggering the orienting of the very same
attentional mechanism, but rather they modulate processing differently. We present a theoretical framework according to which
endogenous predictive cues facilitate target processing by orienting attention, thus amplifying processing at the attended
location. In contrast, apart from attentional orienting, peripherally presented discrepant cues might trigger additional cue-target
event-integration and event-segregation processes, which modulate processing in a different way, thus leading to cueing effects
that are exclusively triggered by peripheral cues. 相似文献

The purpose of this article is to explore the legacy of Charles V. Gerkin’s pastoral theology and to construct a method of pastoral theology. In Part I, I will trace within a larger context of pastoral theology the history of Gerkin’s pastoral theology since his early clinical praxis. In Part II, I will explore his method of developing pastoral theology and construct a renewed critical and constructive method of pastoral theology, reflecting on the implications of exploring the history and method of his pastoral theology. 相似文献

Stress, glucocorticoids and ageing of the immune system 总被引:1,自引:0,他引:1
Bauer ME 《Stress (Amsterdam, Netherlands)》2005,8(1):69-83
Ageing has been associated with immunological changes (immunosenescence) that resemble those observed following chronic stress or glucocorticoid (GC) treatment. These changes include thymic involution, lower number of na?ve T cells, reduced cell-mediated immunity, and poor vaccination response to new antigens. It follows that immunosenescence could be associated with changes of peripheral GC levels. Indeed, when compared with young subjects, healthy elders are more stressed and show activation of the hypothalamus-pituitary-adrenal (HPA) axis. However, both beneficial and undesirable effects of GCs ultimately depend on the target tissue sensitivity to these steroids. Recent data indicate that peripheral lymphocytes from elders respond poorly to GC treatment in vitro. The present review summarizes recent findings which suggest that immunosenescence may be closely related to both psychological distress and stress hormones. Furthermore, chronically stressed elderly subjects may be particularly at risk of stress-related pathology because of further alterations in GC-immune signalling. Finally, the neuroendocrine hypothesis of immunosenescence is finally reconsidered in which the age-related increase in the cortisol/DHEA ratio is major determinant of immunological changes observed during ageing. 相似文献

In the present study, the authors investigated the effects of framing of options on risky decision making in groups of younger adults (M = 23.8 years, n = 192) and older adults (M = 69.1 years, n = 192). The participants were assigned to one of three scenarios varying in the goods at stake (human lives, paintings, money). The authors observed a majority preference in favor of the risky options after negative, but not positive framing. They also found, as they had predicted, that the type of framing effect varied across scenarios, with a bidirectional framing effect for the life-death scenario and unidirectional (risk averse) framing effects when public property (paintings) or personal property (money) were at stake. It is important to note that these choice preference patterns were highly similar across the age groups, which reinforced the conclusion that younger and older adults are equally susceptible to framing effects. 相似文献
