Secular human rights: Challenge and opportunity to Christians and Muslims∗

The principle that all human beings should enjoy equal rights of freedom and participation is a specifically modem idea which initially met with resistance from both Christians and Muslims. Even today Christians and Muslims often have difficulties with recognizing the secularistic features of human rights. The profession of the inalienable dignity of every human person, however, can facilitate a critical reconciliation between the emancipatory ethics of human rights on the one hand and the humanitarian traditions of Christianity and Islam on the other.     

Age-Correlated Incremental Consideration of Velocity Information in Relative Time-to-Arrival Judgments

One hundred fifty-one children and 43 adults judged which of 2 cartoon birds would be the first to arrive at a common finish line. Objects moved unidirectionally along parallel trajectories, either at the same or different speeds, and disappeared at different distances from the goal. Overall, 9–10-year-old children performed as well as adults, but 4–5- and 6–8-year-olds erred significantly more often. On trials for which distance to goal at disappearance was a valid cue, 4–5-year-olds scored 80% correct, and no differences were seen between 6–10-year-olds and adults. On the opposite type of trials, where the trailing bird would win the race, only adults retained their level of performance, and all age groups differed markedly. Findings suggest a gradual developmental transition from a distance-based to a time-based understanding of the task.     

Neural correlates of stimulus response and stimulus outcome shifting in healthy participants and MS patients

Introduction

Adaptation to changing situations can be mediated by two strategies: (1) Evaluation of a response and (2) Evaluation of outcome values in relation to objects. Previous studies indicate that response shifting is associated with a network comprising the left frontal cortex and parietal cortex connected by the superior longitudinal fascicle, whereas outcome evaluation is associated with a network consisting of the orbitofrontal cortex, amygdala and uncinate fascicle. However, these studies rarely compared both kinds of adaptation directly and existing fMRI studies with healthy subjects are not informative about the role of the two fiber systems.

Methods

We analyzed stimulus response shifting and stimulus outcome shifting in two studies, one fMRI-study on healthy participants and one study on patients with MS involving structural MRI (Diffusion Tensor Imaging, Voxel Based Morphometry, Ventricular volumetry). Two tasks were used, identical in presentation but different in instruction, controlling for effects of lower level processing. In the SRS task, participants had to perform a “Go” or “NoGo” response depending on a stimulus change: if the stimulus remained the same, they had to continue with the former type of response, if it changed they had to adapt their response pattern. In the SOS task they had to perform a “Go” response only if the presented stimulus corresponded to that of an internal alternating series.

Results

fMRI findings showed that SRS is related to a bilateral parietal-premotor network. In the left hemisphere the prefrontal cortex was also involved. SOS was lateralized to the right hemisphere, particularly to the anterior temporal pole and amygdala, and the inferior parietal cortex. MS patients impaired on this task suffered from lesions in the right uncinate fascicle and showed an enlarged right frontal lateral ventricle.

Conclusion

With physically identical tasks, a functional neuronal segregation can be demonstrated for stimulus response shifting (bilateral activations with a focus in the left prefrontal cortex) and stimulus outcome shifting (right anterior temporal lobe and right supramarginal gyrus).     

Component processes of phased decision strategies

It is often assumed that decision makers apply mixtures of strategies including heuristic processes in complex choice tasks. In support of this assumption the component processes involved in phased strategies were investigated. Expectations for an experimental investigation were generated by simulations within the effort-quality framework. Effort-quality trade-off functions for tasks of different complexity favor compensatory dimension-based strategies for binary choice. For multialternative choice, a combination of initial dimension-based elimination procedures followed by alternative-based final processing would be expected. These expectations were tested in two experiments. While choosing between two, four, or eight alternatives, subjects could successively retrieve parts of the available information. Depending on their menu selection, either all features of one alternative were displayed together (alternative-based retrieval), or all features on one dimension were displayed together (dimension-based retrieval). Vincent averaging was used to analyze the retrieval sequences with respect to their stationarity. While the stationary sequences for binary choice are compatible with single processing strategies, non-stationarity of the sequences obtained for multialternative choice indicates the use of phased strategies. In particular, non-stationarity due to decreasing dimension-based retrievals over time suggests that subjects first applied dimensional elimination and later derived their choices by more thorough, alternative-based processing of the remaining alternatives.     

Continuous Response Monitoring of Relative Time-to-Contact Judgments: Does Effective Information Change During an Approach Event?

In many previous studies of time-to-contact (TTC) judgments of approaching objects, a response was measured after observers viewed the entire event and was used to infer the informational basis for the judgment. Such measures primarily reflect the information used at the end of the approach event and may not reveal whether observers used different information at different times during the event. Evidence indicates that observers use multiple information sources and that the effectiveness of information varies with distance. We introduce a method in which observers continuously report which of 2 approaching objects would reach them first, throughout the approach. We identified the occurrence and time of response reversals. Most observers changed their relative TTC judgments during the event. The pattern of responses indicated that observers did not use tau early during the approach when objects were far and did not use optical size later when the objects were closer. Most observers relied on either optical size or optical expansion rate early during the approach and expansion rate later during the event, although there were individual differences. A single relative TTC judgment measured after observers view an approach event may not reflect judgments or their informational basis throughout the entire event.     

Independent allocation of attention to eye and hand targets in coordinated eye-hand movements

When reaching for objects, people frequently look where they reach. This raises the question of whether the targets for the eye and hand in concurrent eye and hand movements are selected by a unitary attentional system or by independent mechanisms. We used the deployment of visual attention as an index of the selection of movement targets and asked observers to reach and look to either the same location or separate locations. Results show that during the preparation of coordinated movements, attention is allocated in parallel to the targets of a saccade and a reaching movement. Attentional allocations for the two movements interact synergistically when both are directed to a common goal. Delaying the eye movement delays the attentional shift to the saccade target while leaving attentional deployment to the reach target unaffected. Our findings demonstrate that attentional resources are allocated independently to the targets of eye and hand movements and suggest that the goals for these effectors are selected by separate attentional mechanisms.     

Confucianism between Tradition and Modernity, Religion, and Secularization: Questions to Tu Weiming

The article discusses central assumptions of Tu Weiming’s program of overcoming the “enlightenment mentality” and throws a critical light on his conceptions of religious or spiritual Confucianism, of a Confucian modernity, and of the “multiple modernities” theory in general. It defends a unitary rather than multiple concept of modernity in terms of the realization of a morally controlled “principle of free subjectivity” and tries to show how Confucianism, understood as a secular ethics, could contribute to this goal.     

Relevance of education and intelligence at the national level for health: The case of HIV and AIDS

Studies at the individual level have shown a negative effect of education and intelligence on risky behavior. The same has been demonstrated for risky sexual behavior and for HIV-infection rates in sub-Saharan Africa. In path analyses at the country data level, cognitive abilities (seen as depending on education) show a strong negative effect on HIV-infection rates, whereas gross domestic product and modernization each has a small positive effect. A higher proportion of Muslims in the population reduces the HIV-infection rate. Explanations for the effect of intelligence include a better understanding of causal relationships between one's behavior and health, greater awareness of future consequences, indirect intelligence effects, a general rationality effect, a civic embeddedness effect, and more competent management of the problem by governments, e.g. through public education programs about HIV transmission and AIDS.
