Protecting God from Science and Technology: How Religious Criticisms of Biotechnologies Backfire

Many religious critics argue that biotechnology (such as cloning and genetic engineering) intrudes on God's domain, or plays God, or revolts against God. While some of these criticisms are standard complaints about human hubris, I argue that some of the recent criticism represents a "Promethean" concern, in which believers unreflectively seem to fear that science and technology are actually replicating or stealing God's special deity–defining powers. These criticisms backfire theologically, because they diminish God, portraying God as an anthropomorphic superbeing whose relevance and special nature are increasingly rivaled by human power.     

Relationships between ability and personality:does intelligence contribute positively to personal and social adjustment?

Intelligence/personality associations were studied in four large datasets. Correlations between general ability (g) and major personality traits were generally consistent with previous findings. For other traits, an interpretation of the correlation patterning is that traits classifiable as adaptive in terms of personal and social adjustment have positive correlations with g, whilst maladaptive traits have negative correlations. Regression modelling confirmed these associations and structural equation modelling of selected traits showed that Neuroticism acts as a mediator of g on the outcome. Non-linear relationships between intelligence and personality were not found. In two of the datasets the correlation between Neuroticism and Psychoticism decreased with ability level, and the correlation between fluid and crystallised ability increased with level of Neuroticism.     

There are stable individual differences in performance variability, both from moment to moment and from day to day

Individual differences in decision speed have been regarded as direct reflections of a primitive functional neurophysiological characteristic, which affects performance on all cognitive tasks and so may be regarded as the biological basis of intelligence, or of age-related changes in mental abilities. More detailed analyses show that variability within an experimental session (WSV) is a stable individual difference characteristic and that mean choice reaction times (CRTs) are gross summary statistics that reflect variability, rather than maximum speed of performance. A total of 98 people aged from 60 to 80 years completed 36 weekly sessions on six different letter categorization tasks. After effects of practice and of circadian variability had been eliminated, individuals with lower scores on the Cattell Culture Fair intelligence test had slower CRTs and greater WSV on all tasks. A simulation study showed that the greater WSVs of low Cattell scorers led directly to the significantly greater variability of their mean CRTs from session to session. However because CRTs on tasks co-varied from session to session it was apparent that, besides being affected by WSV, individuals' between-session variabilities (BSVs) also vary because of state changes that affect their performance from day to day. It seems that both variability in performance from trial to trial during a session and variability in average performance from day to day are correlated, stable, individual difference characteristics that vary inversely with intelligence test performance. Methodological consequences of these results for interpretations of age-related cognitive changes, for variability between as well as within individuals, for individual differences in decision speed, and for circadian variability in performance are discussed.     

Viewing-position effects in the Stroop task: Initial fixation position modulates Stroop effects in fully colored words

In two experiments that we conducted with adult (Experiment 1) and child (Experiment 2) participants, we experimentally controlled the eyes' first fixation in the word using a variable viewing-position technique in a classical all-letter-coloring Stroop procedure. We explored the impact of initial-fixation position (optimal viewing position [OVP] vs. end of the word) on the magnitude of Stroop effects (both interference and facilitation). The results showed that both interference and facilitation effects were reduced when the first fixation was located at the end of the word rather than at the OVP. These data make a new contribution to the study of the role of low-level processes in Stroop effects and add support to the growing body of research indicating that oculomotor processes can act as moderators of cognitive processes in the determination of Stroop effects.     

Learning to like it: Aesthetic perception of bodies,movements and choreographic structure

Appreciating human movement can be a powerful aesthetic experience. We have used apparent biological motion to investigate the aesthetic effects of three levels of movement representation: body postures, movement transitions and choreographic structure. Symmetrical (ABCDCBA) and asymmetrical (ABCDBCA) sequences of apparent movement were created from static postures, and were presented in an artificial grammar learning paradigm. Additionally, “good” continuation of apparent movements was manipulated by changing the number of movement path reversals within a sequence. In an initial exposure phase, one group of participants saw only symmetrical sequences, while another group saw only asymmetrical sequences. In a subsequent test phase, both groups rated all sequences on an aesthetic evaluation scale. We found that posture, movement, and choreographic structure all influenced aesthetic ratings. Separate ratings for the static body postures presented individually showed that both groups preferred a posture that maximized spatial symmetry. Ratings for the experimental sequences showed that both groups gave higher ratings to symmetrical sequences with “good” continuation and lower ratings to sequences with many path reversals. Further, participants who had been initially familiarized with asymmetrical sequences showed increased liking for asymmetrical sequences, suggesting a structural mere exposure effect. Aesthetic preferences thus depend on body postures, apparent movement continuation and choreographic structure. We propose a hierarchical model of aesthetic perception of human movement with distinct processing levels for body postures, movements and choreographic structure.     

Beyond sexual recidivism: A review of the sexual criminal career parameters of adult sex offenders

The current study claims that measures of sexual recidivism provide a distorted view of the criminal activity of adult sex offenders. To address this important limitation, the criminal career perspective is presented and key concepts are defined and described. The study also provides an up-to-date review of the scientific literature on various criminal career parameters of the sexual criminal activity of adult sex offenders. Hence, current empirical knowledge on the prevalence, age of onset, frequency, continuity, versatility, and desistance from sex offending is presented. The findings highlight the complexities of the sexual criminal career of adult sex offenders, and most importantly, its dynamic aspect, both of which are not captured by traditional measures of sexual recidivism. The review also underscores the importance of recognizing that sexual offending develops according to a series of stages, that, if not recognized, may lead to the underestimation of risk for some and over-estimation of risk for others. The review provides a framework to stimulate new areas of research as well as policy-development that is not limited to the identification of the “high-risk” convicted sex offenders.     

Parent Alcoholism Impacts the Severity and Timing of Children’s Externalizing Symptoms

Although previous studies show that children of alcoholic parents have higher rates of externalizing symptoms compared to their peers, it remains unclear whether the timing of children’s externalizing symptoms is linked to that of their parent’s alcohol-related symptoms. Using a multilevel modeling approach, we tested whether children aged 2 through 17 showed elevated mother-, father- and child-reported externalizing symptoms (a) at the same time that parents showed alcohol-related consequences (time-varying effects), (b) if parents showed greater alcohol-related consequences during the study period (proximal effects), and (c) if parents had a lifetime diagnosis of alcoholism that predated the study period (distal effects). We used integrative data analysis to combine samples from two prospective studies to test these hypotheses. Distal effects of parent alcoholism on increased child externalizing symptoms were large and consistent. In addition, proximal and time-varying effects of parent alcohol symptoms were also found. Implications for preventing escalations in externalizing symptoms among this high-risk population are discussed.     

Nick Thompson on Design

Most biologists are struck by the many close fits between organisms’ characteristics and the environments which they inhabit. The adaptations look as they have been designed, but their origins are explained in terms of Charles Darwin’s natural selection. Nick Thompson, to whom this essay is dedicated, frequently wrote about design and insisted that the concept should not treated in the same way as the notion of current utility, the idea that an organism’s trait increases its chances of survival and reproductive success. He was right, but sadly the whole idea of design has been appropriated by the creationists seeking scientific respectability for their extremist nonsense. As a result biologists are now shy about using the term.
