OLD TEXTS,NEW MASKS: A CRITICAL REVIEW OF MISREADING EVOLUTION ONTO HISTORICAL ISLAMIC TEXTS

With the increasing interest in Islam and evolution, some Islamic thinkers have vehemently rejected evolution, while others have eagerly embraced it. However, those seeking to embrace evolution sometimes err in their interpretation of historical writings. Indeed, there are texts written by famous historical scholars of Islam who seem to suggest that humans have evolved from lower forms of species. These include Ibn Khaldūn, Jalāl ad‐Dīn Rūmī, al‐Jāhiz, and The Brethren of Purity (Ikhwān al Safā). Although this may be true, such readings are a mistaken interpretation of the aforementioned authors who are actually referring to some form of the scalae naturae (the Great Chain of Being). This reference to the Great Chain of Being is unknown to some contemporary readers who mistakenly believe these writers to be discussing an evolutionary or a proto‐evolutionary theory. This article demonstrates how and why these historical records do not actually represent any notion of evolution as it is currently understood, in the hope of avoiding any further erroneous claims that seem to be proliferating among modern thinkers.     

Digit ratio (2D:4D) and Cattell's personality traits

The ratio between second and fourth finger (2D:4D) is sexually dimorphic; it is lower in men than in women. Studies using broad personality domains yielded correlations of 2D:4D with neuroticism, extraversion or agreeableness, but the obtained results have been inconsistent. We correlated 2D:4D of 184 women and 101 men with their scores in Cattell's 16 Personality Factor (16PF) Questionnaire. We found women with a higher (more ‘feminine’) right hand 2D:4D to score lower in emotional stability and social boldness and higher in privateness. Mediator analysis showed emotional stability to be probably primarily correlated with 2D:4D and to act as a mediator between 2D:4D and social boldness. Privateness appears to be mediated by an even more complex path. We discuss the usefulness of primary‐level personality questionnaires and mediator analyses in the investigation of psycho‐morphological associations. Copyright © 2007 John Wiley & Sons, Ltd.     

Personality traits and endocrine response as possible asymmetry factors of agonistic outcome in karate athletes

Individual variations of plasma levels of hormones testosterone (T) and cortisol (C), before (pre) and after (post) Kumite (real fight) and Kata (ritualized fight) were measured in male karate athletes and analyzed in relation with the agonistic outcome (i.e. winning or losing the fight) and personality trait measures. T and C increased only during Kumite contest and pre‐ and post‐competition C levels were higher in losers than winners. Losers showed higher levels of harm avoidance and anxiety as well as lower level of novelty seeking than winners. Importantly, novelty seeking negatively correlates with pre C and the higher the level of risk assessment, emotionality and insecurity indexes the higher the pre C level. In conclusion, personality traits might be an important factor asymmetry between athletes influencing both the probability of winning or losing an agonistic interaction and the different anticipatory endocrine response to the incipient fight.

Lambda Calculus and Intuitionistic Linear Logic

The introduction of Linear Logic extends the Curry-Howard Isomorphism to intensional aspects of the typed functional programming. In particular, every formula of Linear Logic tells whether the term it is a type for, can be either erased/duplicated or not, during a computation. So, Linear Logic can be seen as a model of a computational environment with an explicit control about the management of resources.This paper introduces a typed functional language ! and a categorical model for it.The terms of ! encode a version of natural deduction for Intuitionistic Linear Logic such that linear and non linear assumptions are managed multiplicatively and additively, respectively. Correspondingly, the terms of ! are built out of two disjoint sets of variables. Moreover, the -abstractions of ! bind variables and patterns. The use of two different kinds of variables and the patterns allow a very compact definition of the one-step operational semantics of !, unlike all other extensions of Curry-Howard Isomorphism to Intuitionistic Linear Logic. The language ! is Church-Rosser and enjoys both Strong Normalizability and Subject Reduction.The categorical model induces operational equivalences like, for example, a set of extensional equivalences.The paper presents also an untyped version of ! and a type assignment for it, using formulas of Linear Logic as types. The type assignment inherits from ! all the good computational properties and enjoys also the Principal-Type Property.     

Event-related potentials in phonological matching tasks

Two experiments investigated Event-Related Potentials (ERPs) in matching tasks. In Experiment 1 subjects judged, in separate conditions, whether two words rhymed or were written in the same case. The CNV developing between the two words was larger in the latter task compared to the former at the right temporal site. In the rhyme judgment task, an increased late negativity differentiated the ERPs to nonrhyming words from those that rhymed with the previously presented word. This difference was maximal at the midline and over the right hemisphere. Experiment 2 further investigated ERPs in the rhyme judgment task, increasing memory demands with an extended interstimulus interval (ISI) and varying the number of items subjects had to hold in memory during this period (one vs. three). Irrespective of memory load, CNVs during the ISI were more negative from the left hemisphere, and the ERPs to the rhyming and nonrhyming words showed the same differences as in Experiment 1. The CNV asymmetries are interpreted as being associated with the engagement of lateralized short-term memory processes. The rhyme/nonrhyme differences are possibly related to the “N400” component elicited by semantically incongruous words. Possible reasons for their scalp distribution are discussed.     

Ear advantages for temporal resolution in baboons

On the assumption that temporal resolution underlies an individual's ear advantage for speech perception, one would predict an ear advantage for a temporal resolution task to correlate precisely with an ear advantage for the discrimination of consonant-vowel syllables that differ in their temporal features. A gap detection task that required the resolution of brief silent intervals in bursts of noise was employed to test this hypothesis in four baboons. The findings offer support for such a hypothesis and thus increase the feasibility of an animal model of functional asymmetry in the auditory system.     

An experimental analysis of exposure to “explicit” heterosexual stimuli as an effective variable in changing arousal patterns of homosexuals

The effect of exposure to explicit heterosexual stimuli on heterosexual arousal was experimentally analyzed in four homosexuals in a series of single case experimental designs. Each subject was sequentially exposed to films of female or male sexual content under positive therapeutic instructions. Penile response to female slides in separate measurement sessions increased during exposure to the female film, decreased during exposure to the male film, and increased once again when the female film was reinstated. The increase in penile response to female stimuli was paralleled in many instances by changes in masturbatory fantasy, reports of arousal and heterosexual behavior outside the laboratory. Increasing heterosexual arousal had little effect on homosexual responsivity. Results are discussed in terms of exposure facilitating extinction of avoidance responses toward females and providing new sexual fantasy content.     

Guilty knowledge versus innocent associations: Effects of trait anxiety and stimulus context on skin conductance

A simulated lie detection procedure was used to investigate skin conductance responsivity among self-reported skin responders. Subjects were grouped according to reported trait anxiety as measured by Lykken's Activity Preference Questionnaire and then engaged in either a mock crime or a neutral activity. The “crime” gave subjects “guilty knowledge,” and the neutral task provided “innocent associations” to relevant stimuli imbedded in each scenario. Subjects were then interrogated using Lykken's Guilty Knowledge technique. Anxiety classification, guilty vs. innocent treatment, and type of stimulus were manipulated in a 2 × 2 × (2) factorial design. Results for differential responsivity scores showed significant main and interaction effects. Low-anxiety subjects showed almost no effects, but highly anxious subjects responded strongly in the “guilty” rather than the “innocent” treatment. Contrary to previous findings, results showed a substantial—but qualified—relationship between self-reported anxiety and electrodermal responsivity. Also, the Guilty Knowledge technique with rank scoring yielded 97.5% correct classification.
