The Translation Issues in the Gender Inclusive Controversy

Abstract

The recently published Today's New International Versionhas received some criticism, especially from The Council on Biblical Manhood and Womanhood, which argues that the TNIVhas gone beyond translation to interpretation in order to further feminist causes. The present author argues that the differences between the TNIVand NIVare standard translation issues, highlighting three key points with illustrations, establishing a case for the superiority of “gender inclusive” translations such as the TNIV. A bibliography for study on both sides is included.     

Are Human Rights Redundant in the Ethical Codes of Psychologists?

The codes of ethics and conduct of a number of psychology bodies explicitly refer to human rights, and the American Psychological Association recently expanded the use of the construct when it amended standard 1.02 of the Ethical Principles of Psychologists and Code of Conduct. What is unclear is how these references to human rights should be interpreted. In this article I examine the historical development of human rights and associated constructs and the contemporary meaning of human rights. As human rights are generally associated with law, morality, or religion, I consider to which of forms of these references most likely refer. I conclude that these references in ethical codes are redundant and that it would be preferable not to refer to human rights in codes. Instead, the profession should acknowledge human rights as a separate and complimentary norm system that governs the behavior of psychologists and should ensure that they have adequate knowledge of human rights and encourage them to promote human rights.     

Human food preferences and cultural identity: The case of Aragón (Spain)

This research aims to analyze the relationship between sociocultural values and human food preferences. The latter, as shown in this paper, are greatly influenced by cultural identity. This work stems from a theoretical context that originated in Europe and the United States towards the mid‐twentieth century, within the field of the anthropology of food. A qualitative and quantitative analysis has been performed in the Comunidad Autónoma de Aragón (Spain). Research methods include focus groups, in‐depth interviews, participant observation, and a questionnaire that was handed out to a representative sample of the Aragonese population (816 people over 21 years of age; confidence level of 95.5% and error margin of ±3.5). Regarding the research outcome, a highly significant qualitative and quantitative connection has been found between food selection and cultural identity. In other words, people prefer to consume foods that are symbolically associated with their own culture, in order to reinforce their sense of belonging. Although this study has been carried out in Aragón, it is our belief that the results can be generalized to other areas. The originality and interest of our findings are notable considering that, to date, few works have analyzed the sociocultural factors motivating food behavior. Moreover, these results could be used by public and private organizations to meet objectives such as health promotion and product marketing.     

Simulating Personal Wealth in the Laboratory

During laboratory gambling tasks participants are not typically allowed to wager their personal wealth. Instead, wealth is simulated by telling participants they have been endowed with game tokens that will be later exchanged for money. Past research indicates that participants undervalue game tokens following this procedure, which leads to elevated risk taking compared to procedures that add saliency or realism to the monetary payoff. A between-subjects experiment tested whether showing a picture of money during the endowment instructions and repeating token-money exchange information during the session influenced participants' preference for risky and riskless options. The results showed no effect of the money picture. However, repeated token-money exchange information significantly decreased risk taking. Together with past studies, this finding suggests that endowment procedures might establish greater value in game tokens, and therefore better simulate personal wealth, when the eventual exchange between game tokens and money is made more salient to participants.     

Interplay of Biomechanical Constraints and Kinematic Strategies in Selecting Arm Postures

In this study, the authors examined the interplay between biomechanics and control strategies in the resolution of excess degrees of freedom at the joint level. Seven participants made aimed arm movements from 30 starting points and several starting postures to targets. Final arm postures for movements to a target exhibited substantial joint angle variation. Through regression modeling and by comparing observed final arm postures with biomechanically plausible postures, the authors identified 3 kinematic strategies: (a) Maintain deviations from the average angle at the starting point to the joint's final posture; (b) make torso rotations that are a fixed proportion of shoulder rotations; and (c) adopt a characteristic combination of 4 wrist-positioning approaches. The results demonstrated that kinematic strategies can account for substantial variance in final arm postures, if one takes into account 2 types of individual differences—those that arise inevitably from biomechanical constraints and those that reflect choices in movement strategy.     

Executive Function in Young Children and Chimpanzees (Pan troglodytes): Evidence From a Nonverbal Dimensional Change Card Sort Task

In this article the authors compared chimpanzees’ executive function with that of children. They developed a nonverbal dimensional change card sorting task, which indexed the development of executive function. Three pairs of mother and offspring chimpanzees and 30 typically developed 5-year-old children were presented with 2 target stimuli and a test stimulus comprising 2 dimensions (size and shape) on a display; they were required to sort the test stimulus according to 1 dimension (e.g., shape). After 5 consecutive correct trials, the participants had to sort the test stimulus according to the other dimension (e.g., size). The results showed that the chimpanzees often failed to sort the test stimuli according to the first and reversed dimensions. On the other hand, the children were correctly able to use both dimensions. These results indicate that chimpanzees may have less developed executive skills than children.     

Center of Gravity Motions and Ankle Joint Stiffness Control in Upright Undisturbed Stance Modeled Through a Fractional Brownian Motion Framework

The authors modeled the center of gravity vertical projection (CG_V) and the difference, CP - CG_V, which, combined, constitute the center of pressure (CP) trajectory, as fractional Brownian motion in order to investigate their relative contributions and t heir spatiotemporal articulation. The results demonstrated that CG_V and CP - CG_V motions are both endowed in complementary tashion with strong stochastic and part-deterministic behaviors. In addition, if the temporal coordinates remain similar for all 3 trajectories by definition, the switch between the successive control mechanisms appears for shorter displacements for CP - CG_V and CG_V than for CP trajectories. Results deduced from both input (CG,) and muscular stiffness (CP - CG_V) thus provide insight into the way the central nervous system regulates stance control and in particular how CG and CP - CG are controlled.     

A Visual Representation and the Control of Manual Aiming Movements

Three experiments were conducted to determine if a representation of the movement environment is functional in the organization and control of limb movements, when direct visual contact with the environment is prevented. In Experiment 1, a visual rearrangement procedure was employed to show that a representation of the environment that provides inaccurate information about the spatial location of a target can disrupt manual target aiming. In Experiment 2, we demonstrated that spatial information about the position of a target can be destroyed by a visual pattern mask, supporting our claim that the representation is visual. A target-cuing procedure was used in Experiment 3 to show that representation of target position can be useful for premovement organization in a targetaiming task. Together our findings suggest that a short-lived visual representation of the movement environment may serve a useful role in the organization and control of limb movements.     

After-Contraction Phenomenon: Influences on Performance and Learning

Three experiments investigated the influence of an after-contraction phenomenon on the performance and learning of a dynamic force-production task. The after-contraction effect refers to an involuntary potentiation (induced by a sustained pre-contraction) that is thought to summate with voluntary motor commands to bias subsequent responding. The precontraction involved a brief (20 s) static contraction. The subsequent influence of the precontraction on a dynamic force-production task was assessed. Experiments 1 and 2 were aimed at demonstrating the direct impact of the precontraction intensity on the magnitude and decay of the after-contraction effect. The results indicated that as the intensity of the precontraction increased, the magnitude of the induced bias increased. In Experiment 3, the indirect influence on subsequent retention of varying the precontraction intensity during acquisition was investigated. The results indicated that the performance of subjects experiencing varying precontraction intensities during acquisition was inferior to that of subjects experiencing a constant precontraction intensity, but the performance of the varied precontraction intensities group was superior on the test of retention. It is noted that the paradoxical reversal from acquisition to retention is similar to that found in contextual interference experiments and may arise from similar mechanisms.
