Habituality and Undecidability: A Comparison of Merleau-Ponty and Derrida on the Decision

This essay examines the relationship that obtains between Merleau-Ponty and Derrida through exploring an interesting point of dissension in their respective accounts of decision-making. Merleau-Ponty's early philosophy emphasizes the body-subject's tendency to seek an equilibrium with the world (by acquiring skills and establishing what he refers to as 'intentional arcs'), and towards deciding in an embodied and habitual manner that minimizes any confrontation with what might be termed a decision-making aporia. On the other hand, in his later writings, Derrida frequently points towards a constitutive 'undecidability' involved in decision-making. He insists that a decision, if it is genuinely to be a decision, must involve a leap beyond all prior preparations, and this ensures that an aporia surrounds any attempt to decide. One must always decide without any equilibrium or stability, and yet these are precisely the things that Merleau-Ponty claims that our body moves us towards. Most of this essay will explore the significance of this disparity, and it will be argued that many of Merleau-Ponty's insights challenge the Derridean conception of the undecidability involved in decision-making. This becomes most obvious when comparing the decision-making processes of those expert in a particular field to those who are merely competent (for example chess), and this essay will attempt to establish that the aporia that Derrida discerns can actually be seen to constrict.     

Shared Expectations and Implicit Coordination in Tennis Doubles Teams

Very little of the existing research on team cognition has looked at sports teams. The purpose of this study was to extend previous research to the sports domain, and empirically test the relationship between one aspect of team cognition—shared expectations—and implicit coordination in 71 American tennis doubles teams. We tested a model hypothesizing a link between prior experience, shared expectations, and implicit coordination. Prior experience influenced implicit coordination directly, as well as through a positive relationship with shared expectations. The findings highlight the potential of using behavioral measures of team coordination in sport psychology.     

Social Psychological Benefits of Gay Games Participation: A Social Identity Theory Explanation

Abstract

Research examining sexual orientation in sport settings has been limited in scope and lacked theoretical frameworks. To extend this body of research, the current study was framed within social identity theory and examined the impact of Gay Games participation on: (a) social identity, self-esteem, and collective esteem; and (b) expected subsequent social change activities following the Games. One hundred and twenty-five lesbian and bisexual athletes competing in Gay Games V participated in this investigation. The athletes completed a demographic profile and an open-ended questionnaire that asked about their Gay Games experience as well as expected social change activities after the Games. A content analysis of the responses revealed themes consistent with social identity theory. Specifically, these individuals identified the role of the Gay Games on social categorization, personal and social identity, and self and collective esteem. Additionally, these women revealed that following the Gay Games they felt more likely to work towards social change by becoming more out, educating others, and working through political channels.     

All else being equal: Are men always higher in social dominance orientation than women?

The belief in the gender invariance of many traits is a view that dominates much of psychology. In social psychology, this position is clearly represented by social dominance theory and the construct of social dominance orientation (SDO) where it is argued that, all else being equal, men will be higher in SDO than women. In other domains, though, these assumptions are being questioned, and researchers are arguing for a gender similarities hypothesis. The argument is that men and women are more similar than different, and where there are effects for gender, these are small. In this investigation, men and women are compared under similar cultural (Study 1), ideological, (Study 2) and status (Study 3) contexts to examine whether, all else being equal, men really are higher in SDO than women. In an additional study (Study 4), a meta‐analysis is conducted aggregating the effect sizes of the previous studies. Results demonstrated either no effect for gender or an interaction between gender and the relevant social context and only a small effect size of gender—findings that disconfirm the ceteris paribus assumption of social dominance theory. In conclusion, the implications of the findings for understanding gender effects in social psychology are discussed. Copyright © 2011 John Wiley & Sons, Ltd.     

Improving general intelligence with a nutrient-based pharmacological intervention

Cognitive enhancing substances such as amphetamine and modafinil have become popular in recent years to improve acute cognitive performance particularly in environments in which enhanced cognition or intelligence is required. Nutraceutical nootropics, which are natural substances that have the ability to bring about acute or chronic changes in cognition have also been gaining popularity in a range of settings and applications including the workplace, driving and in the amelioration of age related cognitive decline. Huperzine A, Vinpocetine, Acetyl-l-carnitine, Rhodiola Rosea and Alpha-lipoic Acid are popular nutritional supplements that have shown promising benefits in improving a range of biological (e.g., blood flow, anti-inflammatory, anti-oxidant, and direct neurotransmitter effects) and cognitive processes from in vitro, animal and human clinical research. We report here the first human randomized clinical trial for cognition in which we administer a combination of Huperzine A, Vinpocetine, Acetyl-l-carnitine, R. Rosea and Alpha-lipoic acid (called Ceretrophin) vs placebo. Sixty participants (40 females and 20 males, with a mean age of 45.4 years, SD = 12.6) completed either the odd or even items from the Raven Advanced Progressive Matrices (APM) at baseline and the opposite odd or even items at week 4 after consuming either the combination nootropic or placebo. A significant study visit (time) × treatment condition interaction was found: F (1, 57) = 7.279, p = 0.009, partial η² = .113, with paired samples t-tests revealing a significant improvement in mean APM score from baseline to retest (week 4) (t(34) = ? 4.045, p < .001) for the Ceretrophin? group. Improvements in APM scores could be attributed to the active intervention over the placebo, indicating that the treatment improved general intelligence. Implications for improving our understanding of the biological basis of intelligence and pharmacologically improving human cognition are discussed.     

Both odor identification and ApoE-ε4 contribute to normative cognitive aging

Research indicates that apoliprotein E (ApoE) plays a role in the development of Alzheimer's disease (AD) and possibly in the cognitive decline associated with normative aging. More recently, researchers have shown that ApoE is expressed in olfactory brain structures, and a relationship among ApoE, AD, and olfactory function has been proposed. In the current analyses, we investigated the contribution of ApoE and odor identification in decline trajectories associated with normative cognitive aging in various domains, using longitudinal data on cognitive performance available from the Swedish Adoption/Twin Study of Aging. Data on both ApoE status and olfactory functioning were available from 455 individuals ranging in age from 50 to 88 years at the first measurement occasion. Odor identification was measured via a mailed survey. Cognitive performance was assessed in up to 5 waves of in-person testing covering a period of 16 years. Latent growth curve analyses incorporating odor identification and ApoE status indicated a main effect of odor identification on the performance level in three cognitive domains: verbal, memory, and speed. A main effect of ApoE on rates of decline after age 65 was found for verbal, spatial, and speed factors. The consistency of results across cognitive domains provides support for theories that posit central nervous system-wide origins of the olfaction-cognition-ApoE relationship; however, olfactory errors and APOE ε4 show unique and differential effects on cognitive trajectory features.     

There goes the neighbourhood: contextual control over the breadth of lexical activation when reading aloud

There are currently two computational accounts of how the time to read pseudohomophones (like BRANE) and their nonword controls (like FRANE) varies with changes in context. In Reynolds and Besner's (2005) account, readers vary the breadth of lexical activation in response to changes in context. A competing account proposed by Kwantes and Marmurek (2007) and independently by Perry, Ziegler, and Zorzi (2007) has readers varying their response criterion in response to changes in context. The present work adjudicates between these two accounts by examining how the effect of neighbourhood density changes as a function of list context when reading pseudohomophones aloud. The results of an experiment and simulations from a leading computational model support the lexical breadth account, but are inconsistent with the response criterion account.     

Parent Involvement in Early Intervention for Disadvantaged Children: Does It Matter?

This study investigated the association between parent involvement in early intervention and children's later school competence. Parents (N = 704) of children participating in the Chicago Longitudinal Study were interviewed retrospectively about their school involvement in preschool and kindergarten. Parents reported on the activities in which they participated and their frequency of program participation. Results indicated that even after controlling for family background, the number of activities in which parents participated in preschool and kindergarten was significantly associated with higher reading achievement, with lower rates of grade retention at age 14 (eighth grade), and with fewer years in special education. The frequency of parent involvement was only marginally associated with reading achievement but was associated with lower rates of grade retention and fewer years in special education. A confirmatory analysis indicated that teacher ratings of parent involvement in first and second grade were significantly associated with higher reading achievement in eighth grade, lower grade retention rates, and lower rates of special education placement through eighth grade. Findings support the benefits of parent involvement in early childhood programs.     

Truth and consequences

In his 1987 paper “Truth or Consequences,” Dan Brock describes a deep conflict between the goals and virtues of philosophical scholarship and public policymaking: whereas the former is concerned with the search for truth, the latter must primarily be concerned with promoting good consequences. When philosophers are engaged in policymaking, he argues, they must shift their primary goal from truth to consequences—but this has both moral and methodological costs. Brock’s argument exemplifies a pessimistic, but not uncommon, view of the possible shape and nature of applied philosophy. The present paper paints a richer and more optimistic picture. It argues that the difference between theoretical philosophy and applied philosophy is not best understood as a choice between truth and consequences. On the contrary, applied philosophers engage in forms of truth-seeking that are properly concerned with consequences—including the consequences of philosophical practice itself.
