Representational momentum contributes to motion induced mislocalization of stationary objects

The influence of a moving target on memory for the location of a briefly presented stationary object was examined. When the stationary object was aligned with the final portion of the moving target's trajectory, memory for the location of the stationary object was displaced forward (i.e., in the direction of motion of the moving target); the magnitude of forward displacement increased with increases in the velocity of the moving target, decreased with increases in the distance of the stationary object from the final location of the moving target, and increased and then decreased with increases in retention interval. It is suggested that forward displacement in memory for a stationary object aligned with the final portion of a moving target's trajectory reflects an influence of representational momentum of the moving target on memory for the location of the stationary object. Implications of the data for theories of representational momentum and motion induced mislocalization are discussed.     

Coping with major life events: the role of spirituality and self-transformation

The aim of the current study was to explore the process of self-transformation as a result of coping with a major life event, and to address the role, if any, that spirituality plays within the coping and transformational process. Using grounded theory methodology, six participants were interviewed over a period of 6 months. The findings, supportive of previous research, produced a preliminary model illustrating transformation as a gradual process. The core category was identified as “openness,” in that by being open to others or to the “Transcendent,” the participants were able to let go and transform. It was theorized that openness, in this sense, enables acceptance of material deriving from a realm of self beyond the everyday ego. Indeed, such a journey of transformation crucially seems to entail expanding the conception of self beyond customary limits. Understood in this way, transformation may be conceptualized as a process of continual movement into the unconscious, where the totality of the self is awakened, resulting in a reinterpretation of life purpose. The consequences of the transformation for participants were positive in nature. The role that spirituality plays within the coping and transformation process was seen to manifest as being subtle and unfolding and/or supportive.     

Cognitive maps and the hippocampus

Following a familiar route and finding a novel route in a familiar environment depend on different cognitive processes and representations. A recent study by Hartley et al. begins to identity the neural basis of route following and wayfinding in humans. Their study also raises important questions about the functions of the hippocampus.     

Does representational momentum reflect a distortion of the length or the endpoint of a trajectory?

Observers viewed a moving target, and after the target vanished, indicated either the initial position or the final position of the target. In Experiment 1, an auditory tone cued observers to indicate either the initial position or the final position; in Experiment 2, different groups of observers indicated the initial position or the final position. Judgments of the initial position were displaced backward in the direction opposite to motion, and judgments of the final position were displaced forward in the direction of motion. The data suggest that the remembered trajectory is longer than the actual trajectory, and the displacement pattern is not consistent with the hypothesis that representational momentum results from a distortion of memory for the location of a trajectory.     

The Relational–Linguistic Spiral: A Model of Language for Theology

This article attempts to sketch out a view of language as a relational–linguistic spiral by discussing some implications of the thought of Ludwig Wittgenstein for language in general. Language is cast as a spiral which revolves around a center of 'human relationality' that anchors all our speech and concepts but which revolves in an ever–widening way into an arena of meaning we call language. Language creates linguistic space for experience and invites one into these new experiences. The borders of our language are thus not the absolute limits of our world but the admitted limits of our experience. Because the enterprise of language is inherently open, there must be a space for theological language and for the possibility at least of the kind of experiences described therein. Tracing the relational 'vectors' involved in language can also provide a platform for theological and even inter–religious dialogue.     

A Critical Response to Zhang Longxi

This is essay is a critical response to Zhang Longxi's argument that Taoist philosophy is susceptible to Derrida's arguments against logocentrism. I present two main arguments. First, I argue that Zhang fails to provide sufficient evidence that would show Taoism is logocentric. Moreover, even if Zhang could provide support for such a claim there cannot be a general deconstructive argument against logocentrism. Derrida's arguments against logocentrism work from within a specific text. The second argument offers reasons for believing Taoism is decidedly not logocentric because it lacks, among other things, the phonocentrism Derrida was intent on criticising. The 'presence' mentioned in Taoist literature is antithetical to the Platonic notion of Forms; it is not the presence of unchanging ideas in a rational mind. Zhuangzi and Plato do not share the similarities attributed to them by Zhang.     

Guidelines for Writing Letters to Patients

Patient letters provide a permanent record of the genetic counseling that was provided and are unique in medical care; rarely do other health care providers send summaries written specifically to their patients and families. We surveyed genetic counseling training program directors and found that while the acquisition of patient letter-writing skills was considered important, there were no specific guidelines made available to students. To develop letter-writing guidelines, we evaluated patient letters, reviewed references on professional correspondence, surveyed the medical literature, and worked with a writing consultant. The guidelines we subsequently developed and present here include a format for writing patient letters, suggestions on presenting medical information in understandable terms, and wording considerations. These patient letter-writing guidelines are intended to serve as a guide for teaching students this important skill and as a resource for practicing health care professionals.     

Emergent Individuals

We explain the thesis that human mental states are ontologically emergent aspects of a fundamentally biological organism. We then explore the consequences of this thesis for the identity of a human person over time. As these consequences are not obviously independent of one's general ontology of objects and their properties, we consider four such accounts: transcendent universals, kind-Aristotelianism, immanent universals, and tropes. We suggest there are reasons for emergentists to favour the latter two accounts. We then argue that within such ontologies, emergentism about properties pushes one to the stronger claim that there are emergent individuals, though not individuals which are dual to person's bodies — substance emergentism, but not substance dualism.
