Kepler’s optics without hypotheses

This paper argues that Kepler considered his work in optics as part of natural philosophy and that, consequently, he aimed at change within natural philosophy. Back-to-back with John Schuster’s claim that Descartes’ optics should be considered as a natural philosophical appropriation of innovative results in the tradition of practical and mixed mathematics the central claim of my paper is that Kepler’s theory of optical imagery, developed in his Paralipomena ad Vitellionem (1604), was the result of a move similar to Descartes’ by Kepler. My argument consists of three parts. First, Kepler borrowed a geometrical model and experiment of optical imagery from the mélange of mixed and practical mathematics provided in the works of the sixteenth-century mathematicians Ettore Ausonio and Giovanni Battista Della Porta. Second, Kepler criticized the Aristotelian theory of light and he developed his own alternative metaphysics. Third, Kepler used his natural philosophical assumptions about the nature of light to re-interpret the model of image formation taken from Della Porta’s work. Taken together, I portray Kepler’s theory of optical imagery as a natural philosophical appropriation of an innovative model of image formation developed in a sixteenth-century practical and mixed mathematical tradition which was not interested in questioning philosophical assumptions on the nature of light.     

Projective Explanation: How Theories Explain Empirical Data in Spite of Theory-Data Incommensurability

In scientific explanations, the explanans theory is sometimes incommensurable with the explanandum empirical data. How is this possible, especially when the explanation is deductive in nature? This paper attempts to solve the puzzle without relying on any particular theory of reference. For us, it is rather obvious that the geometric idea of projection plays a key role in Kepler’s explanation of Tycho Brahe’s empirical data. We discover that a similar mechanism operates in theoretic explanations in general. In short, all theoretic explanations are “projective” explanations. If so, there should be no logical reason why explanans theories cannot be incommensurable with explanandum data. For illustration, we analyse Einstein’s explanation of the results of the Michelson–Morley experiment in some detail.     

Joint response–effect compatibility

When performing jointly on a task, human agents are assumed to represent their coactor’s share of this task, and research in various joint action paradigms has focused on representing the coactor’s stimulus–response assignments. Here we show that the response–effect (R–E) contingencies exploited by a coactor also affect performance, and thus might be represented as if they were used by oneself. Participants performed an R–E compatibility task, with keypresses producing spatially compatible or incompatible action effects. We did not observe any R–E compatibility effects when the task was performed in isolation (individual go–no-go). By contrast, small but reliable R–E compatibility effects emerged when the same task was performed in a joint setting. These results indicate that the knowledge of a coactor’s R–E contingencies can influence whether self-produced action effects are used for one’s own motor control.     

‘Meaning-dawning’ in Wittgenstein’s Notebooks: a Kierkegaardian reading and critique

In this paper, I am going to propose a new reading of Wittgenstein’s cryptic talk of ‘accession or loss of meaning’ (or the world ‘waxing and waning’ as a whole) in the Notebooks that draws both on Wittgenstein’s later work on aspect-perception, as well as on the thoughts of a thinker whom Wittgenstein greatly admired: Søren Kierkegaard. I will then go on to argue that, its merits apart, there is something existentially problematic about the conception that Wittgenstein is advocating. For the renunciation of the comforts of the world that Wittgenstein proposes as a way of coping with the brute contingencies of life seems only to come as far as what Kierkegaard calls ‘infinite resignation’, and this falls far short of the joyful acceptance of existence that appears necessary for inhabiting what Wittgenstein calls a happy world. That is to say, I will show that what Wittgenstein’s proposal lacks is a way of reconnecting with the finite after one has renounced it – the kind of transformation of existence achieved by the person Kierkegaard calls the ‘knight of faith’.     

Shaping achievement goal orientations in a mastery-structured environment and concomitant changes in related contingencies of self-worth

Across three time-points spanning 9 months, changes in achievement goal orientations and contingencies of self-worth were assessed as a function of participating in a mastery-structured academic program for high-ability adolescents (N = 126). Endorsement of mastery goal orientations increased during the program and remained high even after students returned to their home learning environments. In contrast, performance-approach and performance-avoidance goal orientations decreased during the summer program, but returned to previous levels when assessed 6 months later. Latent growth curve models assessed the covariation of performance goal orientations and two contingencies of self-worth (outperforming others and others’ approval) hypothesized to represent elements of performance goal orientations. Changes in the contingency of self-worth based on outperforming others positively covaried with observed changes in both performance goal orientations; however, changes in self-worth contingent on others’ approval did not. Results are discussed in terms of mastery-structured environments’ potential to alter achievement goal orientations via their underlying psychological processes. Implications for achievement goal theory and the design of achievement-oriented environments are discussed.     

Strategies,context, and the mechanism of response inhibition

A series of four experiments investigated Neill’s 11977) claim that there are inhibitory mechanisms in selective attention. It was demonstrated that the evidence supporting the inhibitory theory, namely, the diminished availability of distractor responses during a discretetrials version of the Stroop task is complicated by a number of strategic adaptations to various contingencies within the trial sequence. These results do not support a simple interpretation of response inhibition during the Stroop task.     

BEHAVIORAL CUSPS: A DEVELOPMENTAL AND PRAGMATIC CONCEPT FOR BEHAVIOR ANALYSIS

Most concepts of development explain certain behavior changes as products or markers of the invariable succession of emerging periods, stages, refinements, or achievements that define and order much of an individual's life. A different but comparable concept can be derived from the most basic mechanisms of behavior analysis, which are its environmental contingencies, and from its most basic strategy, which is to study behavior as its subject matter. From a behavior-analytic perspective, the most fundamental developmental questions are (a) whether these contingencies vary in any systematic way across the life span, and thus make behavior change in a correspondingly systematic way; and (b) whether some of these contingencies and their changes have more far-reaching consequences than others, in terms of the importance to the organism and others, of the behavior classes they change. Certain behavior changes open the door to especially broad or especially important further behavior change, leading to the concept of the behavioral cusp. A behavioral cusp, then, is any behavior change that brings the organism's behavior into contact with new contingencies that have even more far-reaching consequences. Of all the environmental contingencies that change or maintain behavior, those that accomplish cusps are developmental. Behavior change remains the fundamental phenomenon of development for a behavior-analytic view; a cusp is a special instance of behavior change, a change crucial to what can come next.     

Mereological bundle theory and the identity of indiscernibles

Paul (Noûs 36:578–596, 2002; Noûs 40:623–659, 2006, The Handbook of Mereology, forthcoming) has argued for a bundle theory of objects that analyzes the bundling relation between properties and objects in terms of parthood relations. In this paper I argue that any mereological bundle theory with the explanatory power of Paul’s theory will entail the principle of the identity of indiscernibles (PII). This is problematic, since similar bundle theories seem to fall to Max Black’s two sphere counterexample to (PII). I argue, however, that a fully developed mereological bundle theory provides a new way of interpreting Black’s two sphere universe that dispels the counterexample. I argue that this solution to Black’s puzzle is superior to other solutions on offer, and consequently that mereological bundle theory is an attractive ontological strategy for friends of (PII).     

Johannes Kepler’s computer simulation of the universe: Some remarks about theory in psychology

Computer simulation may be an overly seductive way of formulating theory in the social sciences. The capability of constructing complex computer simulation models may remove some of the incentive for finding simple laws. This point is illustrated via a fantasy in which the sixteenth century astronomical theorist, Johannes Kepler, uses Ms computer instead of his mind to account for extant data on stellar and planetary motion. Similarities between sixteenth century cosmology and twentieth century psychology are discussed.     

Intersectional Identities,Identity Dimensions,and Academic Contingencies of Self-Worth

Many people rely on academic performance as an important part of their self-concept, or have academic contingencies of self-worth. We compared academic contingencies of self-worth in three groups of participants, who varied in their feelings about two minority identities: sexual minority Asian/Pacific Islanders, straight Asian/Pacific Islanders, and sexual minority Whites. Comparing pairs of groups that shared one marginalized social identity, we confirmed our hypothesis that participants’ feelings about their racial identity related to contingent self-worth differently based on their sexuality; in contrast, participants’ feelings about their sexual identity related to contingent self-worth in the same way regardless of race. The group defined by the intersection of two minority social identities (Asian/Pacific Islander and sexual minority) is of particular interest.     

The Zhuangzi on Coping with Society

Stories in the Zhuangzi detailing expert artisans and other extraordinary people are often read as celebrations of “skills” or “knacks.” In this paper, I will argue that they would be more accurately understood as “coping” stories. Taken as a celebration of one’s “skill” or “knack” they transform the Zhuangzi into an implicit advocate of conforming to, or even identifying with, one’s social roles. I will argue that the stories of artisans and extraordinarily skilled people are less about cultivating one’s talents so as to “find one’s calling,” better fulfill social expectations, or achieve oneness with Dao, than they are concerned with developing strategies for coping with natural and social contingencies. Read in this way, there is much to learn from the Zhuangzi when reflecting on contemporary social and political issues, especially those related to meritocratic hubris.     

The experience of new sensorimotor contingencies by sensory augmentation

Embedded in the paradigm of embodied cognition, the theory of sensorimotor contingencies (SMCs) proposes that motor actions and associated sensory stimulations are tied together by lawful relations termed SMCs. We aimed to investigate whether SMCs can be learned by means of sensory augmentation. Therefore we focused on related perceptual changes. Subjects trained for 7 weeks with the feelSpace belt mapping information of the magnetic north to vibrotactile stimulation around the waist. They experienced substantial changes in their space perception. The belt facilitated navigation and stimulated the usage of new navigation strategies. The belt’s vibrating signal changed to a kind of spatial information over time while the belt’s appeal and perceived usability increased. The belt also induced certain emotional states. Overall, the results show that learning new SMCs with this relatively small and usable device leads to profound perceptual and emotional changes, which are fully compatible with embodied theories of cognition.     

Further Development of the Interpersonal Contingencies Model: Our Reply to the Mezulis & Funasaki and Burwell & Shirk Commentaries

In our reply to the commentaries on Cambron, Acitelli, & Pettit’s paper (this issue), we address the issue discussed in both commentaries: the need to take a developmental approach to the study of gender differences in depression. In response to Mezulis and Funasaki (this issue), we attempt to specify where the Cambron et al. paper supports their point that vulnerability, stress, and vulnerability-stress interaction may vary across domains. We also enumerate several hypotheses that are derived from our model of gender differences in depression. In response to Burwell and Shirk (this issue), we agree with the need to investigate the origin of self-esteem contingencies, and that the measurement of self-esteem contingencies is fraught with problems. We also remind readers that whether examining interpersonal relationship or physical appearance risk factors for depression, we must focus on the extent to which one’s self-esteem is based on that domain.     

Temperament and self‐based correlates of cooperative,competitive and individualistic learning preferences

People vary in the extent to which they prefer cooperative, competitive or individualistic achievement tasks. In this research, we conducted two studies designed to investigate correlates and possible roots of these social interdependence orientations, namely approach and avoidance temperament, general self‐efficacy, implicit theories of intelligence, and contingencies of self‐worth based in others' approval, competition and academic competence. The results indicated that approach temperament, general self‐efficacy and incremental theory were positively related, and entity theory was negatively related to cooperative preferences (|r| range from .11 to .41); approach temperament, general self‐efficacy, competition contingencies and academic competence contingencies were positively related to competitive preferences (|r| range from .16 to .46); and avoidance temperament, entity theory, competitive contingencies and academic competence contingencies were positively related, and incremental theory was negatively related to individualistic preferences (|r| range from .09 to .15). The findings are discussed with regard to the meaning of each of the three social interdependence orientations, cultural differences among the observed relations and implications for practitioners.     

儿童歧视知觉模型述评

Brown和Bigler提出了儿童歧视知觉模型,分析了歧视知觉的三个影响因素:认知因素、情景因素和个体差异因素,每个因素都包含了多个影响儿童歧视知觉的子因素。该模型展示了这些因素影响儿童歧视知觉的机制。完善该模型需要探讨其与信息加工理论、发展群际理论、主观群体动力学模型的兼容性。歧视知觉的类型需要进一步细化,因此在综合主观群体动力学模型和发展模型的基础上提出了歧视知觉的分类方案。未来研究还要进一步探讨情绪、文化以及年龄因素对儿童歧视知觉的影响,并探讨该模型对歧视干预的意义。     

Rule-governed behavior and behavioral anthropology

According to cultural materialism, cultural practices result from the materialistic outcomes of those practices, not from sociobiological, mentalistic, or mystical predispositions (e.g., Hindus worship cows because, in the long run, that worship results in more food, not less food). However, according to behavior analysis, such materialistic outcomes do not reinforce or punish the cultural practices, because such outcomes are too delayed, too improbable, or individually too small to directly reinforce or punish the cultural practices (e.g., the food increase is too delayed to reinforce the cow worship). Therefore, the molar, materialistic contingencies need the support of molecular, behavioral contingencies. And according to the present theory of rule-governed behavior, the statement of rules describing those molar, materialistic contingencies can establish the needed molecular contingencies. Given the proper behavioral history, such rule statements combine with noncompliance to produce a learned aversive condition (often labeled fear, anxiety, or guilt). The termination of this aversive condition reinforces compliance, just as its presentation punishes noncompliance (e.g., the termination of guilt reinforces the tending to a sick cow). In addition, supernatural rules often supplement these materialistic rules. Furthermore, the production of both materialistic and supernatural rules needs cultural designers who understand the molar, materialistic contingencies.     

实质取样对因果强度估计的影响

使用单个目标原因和单个效果的图形集中呈现范式协变关系探讨实质取样增量（12.5%< 50%< 87.5% <100%）对大学生被试因果强度估计的影响。实验结果显示：1）实质取样增加在Power-PC=.50和1协变关系上都导致高估计,在Power-PC=0的协变关系上导致低估计;2）相同实质取样增量对被试在Power-PC=.50（1）协变关系上强度估计的影响符合一次（二次）函数假设。结果说明高实质取样促使被试做出符合理性预期的强度估计,混合假设可以解释被试的强度估计偏离Power-PC值的现象。
