Patterns of theorizing about chess skill – Commentary on Linhares and Freitas (2010) and Lane and Gobet (2011)

Although Linhares and Freitas (2010) have failed to characterize earlier experimental work in chess skill accurately, their conceptual approach of “experience-recognition”-driven problem solving points to the need to incorporate analogical reasoning mechanisms into explanations of how chess players choose the best move in chess. The Lane and Gobet (2011) commentary and the cognitive simulation models that they espouse consist of plausible mechanisms to support choosing a good move, but need additional development to incorporate abstract/semantic information. One possible avenue for future exploration will be to produce hybrid models that use both “piece-on-square” chunk and template representations and abstract high-level representations to guide search in chess.     

Challenging sex segregation: A philosophical evaluation of the football association’s rules on mixed football

The Football Association (FA) has been under pressure to allow girls to play in mixed teams since 1978, following 12-year old Theresa Bennett’s application to play with boys in a local league. In 1991, over a decade after Bennett’s legal challenge, the FA agreed to remove its ban on mixed football and introduced Rule C4 in order to permit males and females to play together in competitive matches under the age of 11. More recently, following a campaign by parents, coaches, local Members of Parliament and the Women’s Sport Foundation, the FA agreed to trial mixed football for the under-12 to under-15 age categories in order to establish, among other things, the risk of injury to players in sex-integrated competitions. A series of exponential changes ensued: between 2010 and 2014, the age at which mixed football was permitted increased from U11 to U16. In 2015, the FA announced the decision to raise the age limit on mixed football from U16 to U18 for the forthcoming 2015–2016 season. We critically examine the reasons given by the FA for enforcing segregated participation beyond the age of 18, namely that males have an unfair advantage and that females face an unacceptable risk of injury. We also discuss the argument that removing the ban might harm the women’s game. In conclusion, we suggest that the FA ought to abandon the ban on mixed football over the age of 18.     

From childhood to senior professional football: A multi-level approach to elite youth football players’ engagement in football-specific activities

ObjectivesThe main aim of this study was to identify the development of engagement in football-specific activities of elite youth association football (soccer) players who have made the transition to senior professional status or not.DesignComparative research design.MethodData were collected from all elite youth players (N = 745) within the age-range of 14–21 years from all Norwegian Premier League clubs, using a retrospective questionnaire. A within elite-group comparison of players who had obtained a senior professional contract or not was conducted by using multi-level modeling (n = 491).ResultsThe results showed that although the professional players reported to have accumulated more overall practice hours than non-professionals from ages 6 to 19 years, none of these differences were significant. The professional players reported to have accumulated significantly more hours in play and coach-led practice at the youngest age categories. No significant differences were identified at older age categories or for other types of football-specific practice at any age.ConclusionsDifferences in performance attainment may be due to variation in the amount and types of football practice at the earliest years of participation, but may also be related to other factors than the number of hours spent in certain football-specific activities. We argue that implementation of multi-level modeling represents an important progression within practice history research, and is necessary to account for the actual individual’s development over time in addition to identify how different variables may affect the developmental process.     

Ordinary experience and the epoché: Husserl and Heidegger versus Rosen (and Cavell)

In various publications, Stanley Cavell and Stanley Rosen have emphasized the philosophical importance of what they both call “the ordinary.” They both contrast their recovery of “the ordinary” with traditional philosophy, including the phenomenological philosophy of Edmund Husserl. In this paper, I address Rosen’s claims in particular. I argue that Rosen turns the real situation on its head. Contra Rosen, it is not the case that the employment of Husserl’s epoché distorts the authentic voice of “the” ordinary—a voice that is clearly audible only from within everyday life. For (pace both Cavell and Rosen) there is no single “voice” of the ordinary: There are many such “voices,” not all of which are to be relied upon. Therefore, if we want to achieve an adequate grasp of ordinary experience, and Rosen does want this, we precisely need the epoché to curtail the misleading messages of certain other “voices of the ordinary.” Moreover, and somewhat surprisingly, this positive evaluation of the Husserlian epoché finds support in Heidegger’s writings from the twenties. I argue that Heidegger, too, believed that the epoché was an indispensable tool for the philosophical attempt to capture ordinary experience.     

Be-ing (you 有) and non-be-ing (wu 無) in the Dao De Jing

This essay questions the meaning of be-ing (you 有) and non-be-ing (wu 無) in the DDJ with regard to the root-source (benyuan 本源) meaning of dao. I first explore the meaning of dao as the dark non-be-ing, revealing the connotations of the distinction between dao and things (daowuqufen 道物區分) by comparison with some forms of Western metaphysics. The meaning of non-be-ing is elaborated in terms of the dynamic meanings of xu 虚 and chong 沖; The play between be-ing and non-be-ing is explored through the lens of yin and yang qi thinking. Qi thinking determines the mutually manifest and mutually interpretive characteristic of be-ing and non-be-ing. Be-ing and non-be-ing thus understood is an ever-flowing and mutually transforming process that penetrates the different levels of dao, things and humans. In the last part I investigate the meaning of “Be-ing comes from non-be-ing”.     

Perception of the standard and the reversed Müller-Lyer figures in pigeons (Columba livia) and humans (Homo sapiens)

The authors compared perception of the standard and reversed Müller-Lyer figures between pigeons (Columbia livia) and humans (Homo sapiens). In Experiment 1, pigeons learned to classify 6 lengths of target lines into "long" and "short" categories by pecking 2 keys on the monitor, ignoring the 2 brackets so placed that they would not induce an illusion. In the test that followed, all 3 birds chose the "long" key more frequently for the standard Müller-Lyer figures with inward-pointing brackets (><) than for the figures with outward-pointing brackets (<>). The subjects' responses were accountable by neither overall lengths of the figures nor horizontal gaps between the 2 brackets. For the reversed figures, effects of the brackets were absent. These results suggested that the pigeons perceived the standard Müller-Lyer illusion but not the reversed one. Experiment 2 confirmed that humans perceived both types of the illusion. Pigeons and humans may perceive the same illusory figures in different ways.     

Anti-Luck Epistemology and Safety’s (Recent) Discontents

Anti-luck epistemology is an approach to analyzing knowledge that takes as a starting point the widely-held assumption that knowledge must exclude luck. Call this the anti-luck platitude. As Duncan Pritchard (2005) has suggested, there are three stages constituent of anti-luck epistemology, each which specifies a different philosophical requirement: these stages call for us to first give an account of luck; second, specify the sense in which knowledge is incompatible with luck; and finally, show what conditions must be satisfied in order to block the kind of luck with which knowledge was argued to be incompatible. What I’ll show here is that the modal account of luck offers a plausible story at the first stage and leads naturally to equally plausible lines to take at the second and third stages, at which a safety condition on knowledge is squarely motivated. There are, however, recent challenges—advanced by Jonathan Kvanvig (Philosophy and Phenomenological Research 77: 272–281, 2008); Kelly Becker (2007); and Jennifer Lackey (Australasian Journal of Philosophy 86(2):255–267, 2008), among others—to the plausibility of the safety-based anti-luck project I’ve sketched here at each of its three stages of development. Once I’ve made precise the challenges, I’ll show why none implies that we abandon the commitments of the safety-based anti-luck project at any of its stages. What we should conclude, then, is that a safety-condition on knowledge is motivated by independently defensible accounts of (1) what luck is; and (2) just how knowledge should be thought incompatible with it.     

Unskilled and unaware--but why? A reply to Krueger and Mueller (2002)

J. Kruger and D. Dunning (1999) argued that the unskilled suffer a dual burden: Not only do they perform poorly, but their incompetence robs them of the metacognitive ability to realize it. J. Krueger and R. A. Mueller (2002) replicated these basic findings but interpreted them differently. They concluded that a combination of the better-than-average (BTA) effect and a regression artifact better explains why the unskilled are unaware. The authors of the present article respectfully disagree with this proposal and suggest that any interpretation of J. Krueger and R. A. Mueller's results is hampered because those authors used unreliable tests and inappropriate measures of relevant mediating variables. Additionally, a regression-BTA account cannot explain the experimental data reported in J. Kruger and D. Dunning or a reanalysis following the procedure suggested by J. Krueger and R. A. Mueller.     

The Paradox of Wuwei? Yes (and No)

This essay considers P. J. Ivanhoe's critical challenge to Slingerland's analysis of wuwei(‘effortless action’). While I agree with Ivanhoe that we should do more work to embody and understand the concept of wuwei, I will defend Slingerland's notion that wuwei involves paradox—particularly in the cases of Zhuangi and Laozi. The present essay is not a defense of the specifics of Slingerland's analysis. Nonetheless, this essay focuses on defending the notion of paradox. Ivanhoe offers an alternative view of wuwei, one that sees the paradox as a riddle. I argue that this kind of formulation would frame the problem of wuwei in an unhelpful manner. I offer several novel ways of overcoming, or at least qualifying, the experience of paradox that seems to be at play in nondoing.     

How (and where) does moral judgment work?

Moral psychology has long focused on reasoning, but recent evidence suggests that moral judgment is more a matter of emotion and affective intuition than deliberate reasoning. Here we discuss recent findings in psychology and cognitive neuroscience, including several studies that specifically investigate moral judgment. These findings indicate the importance of affect, although they allow that reasoning can play a restricted but significant role in moral judgment. They also point towards a preliminary account of the functional neuroanatomy of moral judgment, according to which many brain areas make important contributions to moral judgment although none is devoted specifically to it.     

When, what, and whom to watch? Quantifying attention in ravens (Corvus corax) and jackdaws (Corvus monedula)

Complex social life requires monitoring of conspecifics. The amount and focus of attention toward others has been suggested to depend on the social relationships between individuals. Yet there are surprisingly few experiments that have tested these assumptions. This study compared attention patterns toward conspecifics in two corvid species, ravens (Corvus corax) and jackdaws (Corvus monedula). Birds were confronted with affiliated and non-affiliated conspecifics engaged in foraging and object manipulation. Visual access to the model bird was provided through two observation holes, which allowed measurement of exactly how often and for how long observers watched the other. Overall, ravens were more attentive to conspecifics than were jackdaws. Moreover, only ravens showed higher interest toward food-related than object-related behaviors of the model and toward close affiliates than non-affiliates by increasing the duration rather than the frequency of looks. These results are in accordance with predictions derived from the species' foraging biology and suggest that the facultative social, but highly manipulative, ravens use and value information from others differently than do the obligate social jackdaws.     

The response of guide dogs and pet dogs (Canis Familiaris) to cues of human referential communication (pointing and gaze)

The study raises the question of whether guide dogs and pet dogs are expected to differ in response to cues of referential communication given by their owners; especially since guide dogs grow up among sighted humans, and while living with their blind owners, they still have interactions with several sighted people. Guide dogs and pet dogs were required to respond to point, point and gaze, gaze and control cues of referential communication given by their owners. Results indicate that the two groups of dogs do not differ from each other, revealing that the visual status of the owner is not a factor in the use of cues of referential communication. Both groups of dogs have higher frequencies of performance and faster latencies for the point and the point and gaze cues as compared to gaze cue only. However, responses to control cues are below chance performance for the guide dogs, whereas the pet dogs perform at chance. The below chance performance of the guide dogs may be explained by a tendency among them to go and stand by the owner. The study indicates that both groups of dogs respond similarly in normal daily dyadic interaction with their owners and the lower comprehension of the human gaze may be a less salient cue among dogs in comparison to the pointing gesture.     

Xunzi and the primitivists on natural spontaneity (xìng 性) and coercion

This article explores two opposing views from Warring States China concerning the value of human natural spontaneity (hereafter xìng 性) and large-scale government coercion. On the one hand, the Ruist (Confucian) philosopher Xunzi championed a comprehensive and coercive ethical, political, and social system or Way (dào 道) that he believed would lead to social order and moral cultivation while opposing people’s xìng. On the other hand, the authors of roughly books 8–10 of Zhuangzi, the primitivists, criticized a Way bearing a striking resemblance to Xunzi’s on the grounds that it seriously harms people by opposing their xìng. I argue that the primitivists offer compelling reasons for Xunzi to modify his own Way regarding its relationship with xìng, though their own proposed alternative Way is not very attractive. I conclude with a brief discussion of one primitivist-inspired alternative view found in the Lü Shi Chun Qiu, which plausibly suggests that one way of respecting people’s xìng is by offering them opportunities to explore their natural abilities.     

Neuropsychological Behavioral Inhibition System (BIS) and Behavioral Approach System (BAS) Assessment: A Shortened Sensitivity to Punishment and Sensitivity to Reward Questionnaire Version (SPSRQ–20)

This research was designed to investigate the items and factor structure of the Sensitivity to Punishment and Sensitivity to Reward Questionnaire (SPSRQ) proposed by Torrubia, Avila, Moltó, and Caseras (2001 Spielberger, C. D., Gorsuch, R. L. and Lushene, R. E. 1970. Manual for the State-Trait Anxiety Inventory., Palo Alto, CA: Consulting Psychologists Press.  [Google Scholar]), as a measure of the behavioral inhibition system and behavioral activation system in Gray's reinforcement sensitivity theory. Recent studies that analyzed this instrument by exploratory and confirmatory factor analysis suggest the need for structural refinement. The Spanish version of the SPSRQ was analyzed by exploratory and confirmatory procedures in calibration (n = 2,102) and validation (n = 746) independent samples. In addition, convergent and discriminant validity was evaluated with the Zuckerman–Kuhlman Personality Questionnaire (Zuckerman, Kuhlman, Teta, Joireman, &; Kraft, 1993 Torrubia, R. and Tobeña, A. 1984. A scale for the assessment of susceptibility to punishment as a measure of anxiety: Preliminary results. Personality and Individual Differences, 5: 371–375. [Crossref], [Web of Science ®] , [Google Scholar]), the Impulsiveness, Venturesomeness and Empathy Inventory (S. B. G. Eysenck, Pearson, Easting, &; Allsopp, 1985 Eysenck, S. B. G., Pearson, P. R., Easting, G. and Allsopp, F. J. 1985. Age norms for impulsiveness, venturesomeness and empathy in adults. Personality and Individual Differences, 6: 613–619. [Crossref], [Web of Science ®] , [Google Scholar]) the Neuroticism, Extraversion and Openness Five Factor Inventory (Costa &; McCrae, 1992 Costa, P. T. and McCrae, R. R. 1992. NEO–PI–R professional manual: Revised NEO Personality Inventory (NEO–PI–R) and NEO Five Factor Inventory (NEO–FFI), Odessa, FL: Psychological Assessment Resources.  [Google Scholar]), and the Barratt Impulsiveness Scales (Barratt, 1985 Ball, S. and Zuckerman, M. 1990. Sensation seeking, Eysenck's personality dimensions and reinforcement sensitivity in concept formation. Personality and Individual Differences, 11: 343–355. [Crossref], [Web of Science ®] , [Google Scholar]). Results showed the robustness of a 20-item structure of the SPSRQ, with satisfactory fit adjustment, validity, and reliability. The findings are discussed in terms of the better functioning and sound psychometric properties of the SPSRQ 20-item version for Gray's personality theory.     

Should inter-collegiate football be eliminated? Assessing the arguments philosophically

Recently, there have been discussions about whether or not inter-collegiate football should be eliminated in the US. This article philosophically assesses the arguments for its elimination as well as the arguments proffered against its elimination. While a variety of arguments are discussed, a new one is brought into the foray of philosophical investigation, one that combines the unfairness and economic arguments: the health care and medical costs to others argument. It is believed that this argument is sufficient to justify the elimination of inter-collegiate football.     

Validation of the French version of Brandtstädter and Renner's Tenacious Goal Pursuit (TGP) and Flexible Goal Adjustment (FGA) scales

IntroductionDespite the potential usefulness of the TGP/FGA scales (Brandtstädter and Renner, 1990) for studying the way people adapt with age, there is little psychometric evidence supporting the validity of the construct of either scale.ObjectiveThe aim of the study was to develop a French version of Brandtstädter's TGP/FGA scales in order to provide a self-report measure for French people in the field of gerontology.MethodTwo studies involving 677 participants were conducted to evaluate the construct validity, reliability and convergence validity of these scales.ResultsIn accordance with Brandtstädter, two factors emerged from the exploratory factorial analysis (study 1): tenacious goal pursuit and flexible goal adjustment. However, 10 items were removed because of factorial loadings. A confirmatory factor analysis (study 2) of the 20 remaining items corroborated a two-factor uncorrelated model of the TGP/FGA scales. The simplified subscales showed good internal consistency. As expected, higher scores on the TGP/FGA scales were correlated with good life satisfaction, greater control and less depression. Finally, the TGP scale was negatively related to age, but the FGA was not.ConclusionThe French adaptation of the TGP/FGA scales was shown to possess satisfactory psychometric properties and may therefore be a valuable instrument for researchers and clinicians who are interested in exploring adaptive processes in the maintenance and promotion of personal well-being.     

Evelyn Underhill (1875–1941): mysticism and worship

This article focuses on some themes in the work of Evelyn Underhill (1875–1941). It is now over a century since she began work on the first version of Mysticism (1911). She was a pioneer not only in the study she undertook for this book, but in the specifically Christian theology she was bold enough to work out from it, with Christ in person the paradigm mystic. The Latin Mass of her day she deemed both as recapitulating Christ's own experience, as well as re-presenting the stability and growth of his ‘Body’ present at the Eucharist. Once recommitted to the Church of England in 1921, at a time of liturgical revision and in a deeply troubled political era, her concentration on Christ's sacrifice led her to embrace pacifism as the world lurched towards World War II. Her theological work, summed up in her final major book Worship (1936), reveals her continuing preoccupation with the question of how Christology integrates with liturgy, and therefore with the living of a distinctively Christian life.     

Stocks and losses, items and interference: A reply to Oberauer and Süß (2000)

Results of a recent study of spatial working memory are presented in support of the claim by Jenkins and her colleagues (Jenkins, Myerson, Hale, &; Fry, 1999) that secondary tasks produce larger interference effects in individuals with higher simple spans than in individuals with lower simple spans. Because spans and interference effects were assessed independently, this study refutes the claim by Oberauer and Süß (2000) that the relation between span and interference effect size is merely an artifact of regression to the mean. In contrast with the present findings, Oberauer and Süß did not find evidence of larger interference effects in higher span individuals, but the reason for this may be straightforward: The secondary tasks that they used did not produce significant interference. Recent findings by Logie and his colleagues indicate that phonological similarity and word length effects are larger in individuals with higher word spans (Logie, Della Sala, Laiacona, Chalmers, &; Wynn, 1996). These results, those of Jenkins, Myerson, et al. (1999), and the results reported here suggest that, across individuals, the absolute effect size for many manipulations that decrease memory span is an increasing function of simple span.
