Three ways of watching a sports video

It does not typically seem to be worthwhile rewatching a sport match, for example, in a video recording, once the result is known. Sports matches are like detective stories. Once one knows ‘whodunit’, there seems little point in revisiting the tale. By drawing on an argument from musicologist Edward T. Cone, this paper argues that certain sports matches may be revisited with profit. The initial experience of a game may be of a series of events that are often ambiguous or confusing as to their meaning or purpose. The full appreciation of a sport match requires, not just this initial familiarity with the immediately perceived events of the game, but also an awareness of the tactics being deployed by both sides. An understanding of tactics and strategy is akin to the analysis of a piece of music (or other art work). A further (third) viewing of the game, during which one can appreciate how the tactics inform the events naively experienced in the first viewing, will yield, it will be argued, an aesthetic pleasure. This takes the experience of sport beyond the merely entertaining or exciting. In certain games, the third viewing may also transcend an appreciation of the merely formal qualities of the game, and so offer substantial insights into what it is to be human.     

How the Abstract Becomes Concrete: Irrational Numbers Are Understood Relative to Natural Numbers and Perfect Squares

Mathematical cognition research has largely emphasized concepts that can be directly perceived or grounded in visuospatial referents. These include concrete number systems like natural numbers, integers, and rational numbers. Here, we investigate how a more abstract number system, the irrationals denoted by radical expressions like , is understood across three tasks. Performance on a magnitude comparison task suggests that people interpret irrational numbers (specifically, the radicands of radical expressions) as natural numbers. Strategy self‐reports during a number line estimation task reveal that the spatial locations of irrationals are determined by referencing neighboring perfect squares. Finally, perfect squares facilitate the evaluation of arithmetic expressions. These converging results align with a constellation of related phenomena spanning tasks and number systems of varying complexity. Accordingly, we propose that the task‐specific recruitment of more concrete representations to make sense of more abstract concepts (referential processing) is an important mechanism for teaching and learning mathematics.     

主题情境和信任特质对大学生信任圈的影响

以395名大学生为被试,采用2×4×2的混合设计考察了主题情境(内容和风险等级)和信任特质对大学生信任圈规模和成分的影响。结果表明:(1)主题情境的内容对信任圈的规模和成分均有影响,在借钱情境下的信任圈规模显著大于分享负面信息情境,且两者的信任对象排序也有所不同;(2)随着主题情境的风险等级提高,两种情境下的信任圈规模均减少,但借钱情境下的信任圈规模减少更多,四种风险下信任圈成分无显著变化;(3)信任特质对两种主题情境下的大学生信任圈规模均有显著影响,高信任的被试信任圈规模较大,但对信任圈成分无显著影响;(4)信任圈成分总体呈现出亲人、熟人和陌生人的差序格局。     

Further developments of the concept of fantasy

After the Isaacs' seminal work on the nature and function of unconscious phantasy (1948), several authors (mostly in the British Society) have reflected on the topic and tried to extend the concept of fantasy. In this paper I shall examine the contributions of Winnicott, Gaddini, Joseph and Anne Marie Sandler that aim at broadening this psychoanalytic concept. The authors that I have considered share a focus mostly on the early stages of child development. Both Winnicott and Gaddini belong to a line of thinking that explores the vicissitudes of the primary emotional development of the infantile self (in the mother‐infant relationship) involving the earliest processes of holding and bodily and kinaesthetic fantasy that form the bodily integrity of the person. The Sandlers focused mostly on the concept of the past unconscious understood as a place of primitive vicissitudes with a deficit in figuration where the process of repression is missing. The present unconscious phantasy (that is located in the here and now) has the function of rendering the past unconscious phantasy partly accessible; otherwise it would remain unknowable.     

Analysis of Variance Models with Stochastic Group Weights

The analysis of variance (ANOVA) is still one of the most widely used statistical methods in the social sciences. This article is about stochastic group weights in ANOVA models – a neglected aspect in the literature. Stochastic group weights are present whenever the experimenter does not determine the exact group sizes before conducting the experiment. We show that classic ANOVA tests based on estimated marginal means can have an inflated type I error rate when stochastic group weights are not taken into account, even in randomized experiments. We propose two new ways to incorporate stochastic group weights in the tests of average effects – one based on the general linear model and one based on multigroup structural equation models (SEMs). We show in simulation studies that our methods have nominal type I error rates in experiments with stochastic group weights while classic approaches show an inflated type I error rate. The SEM approach can additionally deal with heteroscedastic residual variances and latent variables. An easy-to-use software package with graphical user interface is provided.     

Effects of Friendship Circles on the Social Interactions of Elementary Age Students with Mild Disabilities

This study assessed the effects of Friendship Circles on the social interactions between students with mild disabilities and their nondisabled peers. A multiple probe design was used to analyze the social interactions during lunch. Data also were collected in the form of sociograms and anecdotal records. In addition, generalization was assessed during recess observations. Results indicated that the Friendship Circle intervention produced increases in appropriate interactions at lunch for all three students and for two there were increases in friendly play at recess. Anecdotal data suggested improved social interactions for two of the students throughout the day and improved social behaviors in the general education classroom such as cooperation during group activities. Implications for future research are discussed.     

The early history of lay analysis,especially in Vienna,Berlin and London: Aspects of an unfolding controversy (1906‐24)1,2

Before the First World War, it had been taken for granted that psychoanalysis was carried out by doctors. The IPA, however, also included non‐physicians. This corresponded to Freud's view that psychoanalysis was a basic science (psychology of the unconscious) with manifold fields of application in medicine as well as in the humanities. It was for the latter application that Freud specifically recruited a number of researchers, e.g. Rank. After 1918, helped by a general boom in psychotherapy, these people too began to work as therapists. This led to a debate about lay analysis within the ‘Secret Committee’ that has so far received little attention and is one focus of this paper. Abraham had only allowed doctors to become members of his group. Similarly the Berlin Policlinic was established as a place for the postgraduate training of doctors. On the other hand, Freud (together with Rank) continued to maintain his broader view of psychoanalysis. In 1920/21, he already wished that analysts would not become a subgroup within the medical profession, but a profession of their own, defined by their special training. The big problem of the late 1920s, that different attitudes to the lay question threatened the autonomy of local or national groups and the integration of the IPA, also became visible at that early time in a conflict between London (Jones) and Vienna/Berlin.     

Expanding the moral circle: Inclusion and exclusion mindsets and the circle of moral regard

The human tendency to draw boundaries is pervasive. The ‘moral circle’ is the boundary drawn around those entities in the world deemed worthy of moral consideration. Three studies demonstrate that the size of the moral circle is influenced by a decision framing effect: the inclusion-exclusion discrepancy. Participants who decided which entities to exclude from the circle (exclusion mindset) generated larger moral circles than those who decided which to include (inclusion mindset). Further, people in an exclusion mindset showed “spill-over” effects into subsequent moral judgments, rating various outgroups as more worthy of moral treatment. The size of the moral circle mediated the effects of mindset on subsequent moral judgment. These studies offer an important first demonstration that decision framing effects have substantial consequences for the moral circle and related moral judgments.     

Testing a unidimensional,qualitative unfolding model for attitudinal or developmental data

Assuming that subject responses rank order stimuli by preference, statistical methods are presented for testing the hypothesis that responses conform to a unidimensional, qualitative unfolding model and to an a priori stimulus ordering. The model postulates that persons and stimulus variables are ordered along a single continuum and that subjects most prefer stimuli nearest their own position. The underlying continuum need not form an interval scale of the stimulus attribute. The general assumptions of the test for the unfolding model make it suitable for the analysis of structure in attitude responses, preference data, and developmental stage data.This research was supported by a grant from the U.S. Public Health Service (Grant No. 1-R01-MH27861-01) to the University of Minnesota. I wish to thank Sanford Weisberg for his helpful suggestions. I also wish to thank Karen Kitchener and Patricia King for letting me use their data.
