Parity of match play: an LPGA replication

This study investigated whether the slight advantage of higher seeded players to win in match play on the men's Professional Golfers' Association Tour generalizes to the Ladies Professional Golf Association Tour. Analysis showed no significant advantage for the higher seeded player in match play. The highly restricted range of skill of tour players makes it mainly a matter of chance who will win any match-play event or who will have the better or worse scores on any given day.     

The effects of play materials on social play

To increase cooperative and social behaviors in children, contingency management programs have been successfully employed. This study examined the possibility that children's social behavior might also be significantly influenced by the nature of the available play materials. Children in an urban recreation center were systematically provided with toys designed for social or isolate play. It was found that social play occurred only 16% of the time when the children were provided with "isolate" toys, whereas social play occurred 78% of the time when children were provided with "social" toys. Thus, the selection of play materials should be an important consideration in any effort to teach children social behaviors.     

The myth of the encoding-retrieval match

Modern memory researchers rely heavily on the encoding-retrieval match, defined as the similarity between coded retrieval cues and previously encoded engrams, to explain variability in retention. The encoding-retrieval match is assumed to be causally and monotonically related to retention, although other factors (such as cue overload) presumably operate in some circumstances. I argue here that the link between the encoding-retrieval match and retention, although generally positive, is essentially correlational rather than causal--much like the link between deep/elaborative processing and retention. Empirically, increasing the functional match between a cue and a target trace can improve, have no effect, or even decrease retention performance depending on the circumstance. We cannot make unequivocal predictions about retention by appealing to the encoding-retrieval match; instead, we should be focusing our attention on the extent to which retrieval cues provide diagnostic information about target occurrence.

Match making and match breaking: The nature of match within and around job design

We explore the notion of ‘match’. In the context of job design, this is congruence or correspondence between two or more job characteristics (e.g. cognitive demands and cognitive control). This congruence is thought to benefit health, well‐being, and performance. The origins of the match concept lie in buffering models of work stress, where resources such as workplace social support and job control are thought to attenuate deleterious effects of adverse job characteristics like excessive job demands. We outline the historical developments in work stress research that has led to notions of match, contrast match with the related concept of person‐environment fit, explore current conceptualizations and operationalizations of match, and outline how the concept of match can be developed.     

先秦儒家美学之"美"的边界

“Beauty” is a very important concept in Pre-Qin Confucian aesthetics. Pre-Qin Confucian aesthetics generally had two viewpoints when defining beauty: Negatively, by stressing that “beauty” in the aesthetic sense was not “good”; and positively, by stressing two factors: one, that beauty was related to “feeling” which was not an animal instinct, the other was that “beauty” was a special texture with a particular meaning. “Beauty” in Pre-Qin Confucian aesthetics may be defined as “texture (or form)” capable of communicating feeling or triggering a reaction of feeling. __________ Translated from Shanghai shifan daxue xuebao 上海师范大学学报 (Journal of Shanghai Normal University), 2007, (7): 80–85     

Musings about beauty

In this essay, I explore how cognitive science could illuminate the concept of beauty. Two results from the extensive literature on aesthetics guide my discussion. As the term “beauty” is overextended in general usage, I choose as my starting point the notion of “perfect form.” Aesthetic theorists are in reasonable agreement about the criteria for perfect form. What do these criteria imply for mental representations that are experienced as beautiful? Complexity theory can be used to specify constraints on mental representations abstractly formulated as vectors in a high‐dimensional space. A central feature of the proposed model is that perfect form depends both on features of the objects or events perceived and on the nature of the encoding strategies or model of the observer. A simple example illustrates the proposed calculations. A number of interesting implications that arise as a consequence of reformulating beauty in this way are noted.     

The robust beauty of majority rules in group decisions

How should groups make decisions? The authors provide an original evaluation of 9 group decision rules based on their adaptive success in a simulated test bed environment. When the adaptive success standard is applied, the majority and plurality rules fare quite well, performing at levels comparable to much more resource-demanding rules such as an individual judgment averaging rule. The plurality rule matches the computationally demanding Condorcet majority winner that is standard in evaluations of preferential choice. The authors also test the results from their theoretical analysis in a behavioral study of nominal human group decisions, and the essential findings are confirmed empirically. The conclusions of the present analysis support the popularity of majority and plurality rules in truth-seeking group decisions.     

Meaning and beauty

What place do experiences of beauty have in a meaningful life? A marginal one, at best, it would seem, if one looks at the current literature in analytic philosophy. Treatments of beauty within so-called “analytic existentialism” tend to suffer from four limitations: beauty is neglected, reduced to artistic production, saddled to theology, or taken as a mere application of a broader theoretical framework. These discussions fail to engage with the rich tradition of philosophical aesthetics. In this essay, I begin by responding to the contention that experiences of beauty cannot lend life meaning because they are passive. Drawing on work in philosophical aesthetics, I then argue that encounters with the beautiful count as genuinely meaning-conferring because they have features commonly taken as marks of meaningfulness.     

The language of social pretend play

The literature dealing with the structure and communication of social pretend play activity in preschool-age children is examined. The two objectives of this review were to determine (1) whether there are any differences in the linguistic forms and expressions children use in pretend as opposed to nonpretend activity and (2) whether age-related differences appear in the language of social pretending over the preschool years. The results of a cross-sectional study of a number of linguistic features occurring in the pretend and nonpretend activities of 35 dyads of children are also presented. The evidence supports the hypotheses that the language of social pretending differs from that of other social activities at several levels of language organization and that some of these differences in the “language of social pretending” appear at different ages during the preschool years. Suggestions are made for further research on the communicative techniques by which social pretend interactions are achieved.     

The appraisal of facial beauty is rapid but not mandatory

Facial attractiveness is an important source of social affective information. Here, we studied the time course and task dependence of evaluating attractive faces from a viewer’s perspective. Event-related brain potentials (ERPs) were recorded while participants classified color portraits of unfamiliar persons according to gender and facial attractiveness. During attractiveness classification, enhanced ERP amplitudes for attractive and nonattractive faces relative to faces of intermediate attractiveness were found for an early component around 150 msec and for the late positive complex (LPC). Whereas LPC enhancement conforms to previous studies employing various types of affective stimuli, the finding of an early effect extends earlier research on rapid emotion processing to the dimension of facial attractiveness. Dipole source localization of this early ERP effect revealed a scalp distribution suggesting activation of posterior extrastriate areas. Importantly, attractiveness-related modulations of brain responses were only marginal during the gender decision task, arguing against the automaticity of attractiveness appraisal.     

Ross on sleeping beauty

In two excellent recent papers, Jacob Ross has argued that the standard arguments for the ‘thirder’ answer to the Sleeping Beauty puzzle lead to violations of countable additivity. The problem is that most arguments for that answer generalise in awkward ways when he looks at the whole class of what he calls Sleeping Beauty problems. In this note I develop a new argument for the thirder answer that doesn't generalise in this way.
