Effects of joint immobilization on standing balance

We investigated the effect of joint immobilization on the postural sway during quiet standing. We hypothesized that the center of pressure (COP), rambling, and trembling trajectories would be affected by joint immobilization. Ten young adults stood on a force plate during 60 s without and with immobilized joints (only knees constrained, CK; knees and hips, CH; and knees, hips, and trunk, CT), with their eyes open (OE) or closed (CE). The root mean square deviation (RMS, the standard deviation from the mean) and mean speed of COP, rambling, and trembling trajectories in the anterior–posterior and medial–lateral directions were analyzed. Similar effects of vision were observed for both directions: larger amplitudes for all variables were observed in the CE condition. In the anterior–posterior direction, postural sway increased only when the knees, hips, and trunk were immobilized. For the medial–lateral direction, the RMS and the mean speed of the COP, rambling, and trembling displacements decreased after immobilization of knees and hips and knees, hips, and trunk. These findings indicate that the single inverted pendulum model is unable to completely explain the processes involved in the control of the quiet upright stance in the anterior–posterior and medial–lateral directions.     

Preschoolers favor the creator's label when reasoning about an artifact's function

The creator of an artifact, by virtue of having made the object, has privileged knowledge about its intended function. Do children recognize that the label an artifact's creator uses can convey this privileged information? 3- and 4-year-olds were presented with an object that looked like a member of one familiar artifact category, but which the speaker referred to with the label of a different familiar category (e.g. a key-like object was called a "spoon"). Children who heard the speaker refer to the object as something she made were more likely to assign its function on the basis of the anomalous label she used than those who heard it referred to as something the speaker found. Thus, even very young children expect a unique connection between the label the creator of an artifact uses and the function she intends it to have.     

“Working with Couples: Satir and the Tao,”

SUMMARY

One of Virginia Satir's greatest gifts to the world was the use of herself as an instrument of healing. By daring to use all of her-self-body, mind and spirit-the connections Virginia made with others were warm and real. Besides being authentically caring, Satir worked out of a pluralistic and comprehensive theoretical base to individualize each intervention. By co-creating strong, trusting relationships she inspirited others with her own life-force energy, and enabled them to become more fully human. Able to put her own ego needs aside, Virginia modeled how to join common sense with a sense of high purpose.     

Understanding response patterns in dyadic conflict: An interactive approach combining self‐construal and opponent's dominance‐submissiveness

Previous works on the effect of self‐construal in interpersonal behaviours tend to adopt a main effect approach. The present research proposes an interactive approach in understanding two response patterns in dyadic conflict by combining self‐construal and the stance of the opponent. Independent self‐construal was hypothesised to be associated with a self‐centred pattern of conflict response, which is characterised by taking contending responses regardless of whether the stance of the opponent is dominant or submissive. Relational self‐construal was hypothesised to be associated with a tuning‐in pattern of conflict response, which is characterised by showing contending responses when the opponent is submissive but yielding responses when the opponent is dominant. With trait self‐construal measured and opponent's stance manipulated, Study 1 provided initial support for the hypotheses. Study 2 showed a three‐way interaction effect between trait self‐construal, manipulated self‐construal and the opponent's stance on actual conflict responses during discussion of a scenario. The effect of self‐construal manipulation was only observed among people who were low in trait independent self‐construal and average in trait relational self‐construal. The results pinpoint the importance of considering personal and opponent factors simultaneously in understanding the dynamics of dyadic conflict processes.     

On What Empiricism Cannot Be

Bas C. van Fraassen, in his Terry Lectures at Yale University (subsequently published as The Empirical Stance), is concerned to elucidate what empiricism is, and could be, given past and current failures of characterization. He contends that naïve empiricism—the metaphilosophical position that characterizes empiricism in terms of a thesis—is self‐refuting, and he offers a reductio ad absurdum to substantiate this claim. Moreover, in place of naïve empiricism, van Fraassen endorses stance empiricism: the metaphilosophical position that characterizes empiricism in terms of certain attitudes and commitments. The present article, however, argues that van Fraassen begs the question in his reductio of naïve empiricism, and thus that his primary defense of stance empiricism is inadequate.     

CUI BONO? A REVIEW OF BREAKING THE SPELL: RELIGION AS A NATURAL PHENOMENON BY DANIEL C. DENNETT

The three requirements for a Darwinian evolutionary process are replication, variation and selection. Dennett (2006) discusses various theories of how these three processes, especially selection, may have operated in the evolution of religion. He believes that the origins of religion, like the origins of language and music, may be approached scientifically. He hopes that such investigations will open a dialog between science and religion leading to moderation of current religious extremism. One problem with Dennett's program, illustrating the difficulty of breaking away from creationist thinking, is Dennett's own failure to consider how Darwinian methods may be used to study evolution of behavioral patterns over the lifetime of individual organisms.     

Pluralistic Ignorance and Political Correctness: The Case of Affirmative Action

The pressure to appear politically correct can have important consequences for social life. In particular, the desire to appear politically correct, and to avoid being seen as racist, sexist, or culturally insensitive, can lead people to espouse publicly support for politically correct issues, such as support for affirmative action, despite privately held doubts. Such discrepancies between public behavior and private attitudes, when accompanied by divergent attributions for one's own behavior and the identical behavior of others, can lead to pluralistic ignorance. Two studies investigated pluralistic ignorance with respect to affirmative action among undergraduates. Their survey responses indicate that people overestimate their peers' support for affirmative action and underestimate their peers' opposition to affirmative action, that people's ratings of the political correctness of supporting affirmative action are correlated with their overestimation of support for affirmative action, and that people view their own attitudes toward affirmative action as unique.     

Katz’s Revisability Paradox Dissolved

Quine's holistic empiricist account of scientific inquiry can be characterized by three constitutive principles: noncontradiction, universal revisability and pragmatic ordering. We show that these constitutive principles cannot be regarded as statements within a holistic empiricist's scientific theory of the world. This claim is a corollary of our refutation of Katz's [1998, 2002] argument that holistic empiricism suffers from what he calls the Revisability Paradox. According to Katz, Quine's empiricism is incoherent because its constitutive principles cannot themselves be rationally revised. Using Gärdenfors and Makinson's logic of belief revision based on epistemic entrenchment, we argue that Katz wrongly assumes that the constitutive principles are statements within a holistic empiricist's theory of the world. Instead, we show that constitutive principles are best seen as properties of a holistic empiricist's theory of scientific inquiry and we submit that, without Katz's mistaken assumption, the paradox cannot be formulated. We argue that our perspective on the status of constitutive principles is perfectly in line with Quinean orthodoxy. In conclusion, we compare our findings with van Fraassen's [2002] argument that we should think of empiricism as a stance, rather than as a doctrine.     

Infostorms

It has become a truism that we live in so‐called information societies where new information technologies have made information abundant. At the same time, information science has made us aware of many phenomena tied to the way we process information. This article explores a series of socio‐epistemic information phenomena resulting from processes that track truth imperfectly: pluralistic ignorance, informational cascades, and belief polarization. It then couples these phenomena with the hypothesis that modern information technologies may lead to their amplification so as to give rise to what are called “infostorms.” This points to the need for studying further the exact relations between information technologies and such infostorms, as well as the ways we may design technologies to avoid being misled away from what we have good reasons to believe.     

Metatherapeutic communication: an exploratory analysis of therapist-reported moments of dialogue regarding the nature of the therapeutic work

The purpose of the study was to investigate the nature of metatherapeutic communication (MTC), defined as dialogue between therapists and clients on the nature of the therapeutic work and the means by which it can be of greatest help to clients. Twelve counselling psychologists, working pluralistically with 35 clients experiencing depression, described on post-session forms moments of negotiation and collaboration around the therapeutic work. Two main dimensions of MTC were identified: the subject matter of the MTC and the temporal focus of the MTC. In addition, MTC varied by the time at which it took place. These findings provide a framework for understanding the nature of MTC in counselling and psychotherapy, and the opportunities for implementing it in practice.
