Moral Utilitarianism and Attitudes Toward Animals

The majority of studies investigating attitudes toward animals have underscored the role of demographic and personality factors. The study of the role of general moral worldviews on attitudes toward animals represents an important complementary perspective. In the current study, we analyzed the relationship between moral utilitarianism toward humans and attitudes toward animals. In psychological and neuroscientific studies, moral utilitarianism has been shown to be related to empathy deficits. We expected that utilitarian decision making would be related to the endorsement of an instrumental representation of animals. We measured utilitarianism with the trolley problem, a hypothetical moral dilemma widely used in the psychological study of moral reasoning. A sample of 20,474 French adults answered an online survey measuring attitudes toward animals and moral decision making involving human beings. Results showed that irrespective of participants’ age and gender, there was a slight relationship between utilitarianism measured by the trolley dilemma and the endorsement of an instrumental representation of animal. Limitations and implications for future research are considered.     

Spatial navigation: Cognitive variables involved in route retracing among an elderly population

The cognitive processes involved in route retracing are not well known. This study aims to highlight them in an elderly population in which contradictory results have been obtained, certain studies showing specific difficulties for route retracing, others not. Thirty-nine elderly subjects performed a route-learning task (forward-backward) in a garden, then completed spatial knowledge tasks and standardised cognitive tests. Results show four factors that were predictive of route retracing performance: route repetition, the pointing task, and two standardised cognitive tests, one assessing spatial working memory, and another global cognitive efficiency. According to these results, route retracing involves route and survey knowledge (i.e., egocentric and allocentric strategy), and the integration of forward-backward perspectives is underpinned by the spatial working memory. Moreover, the subjects did not make more errors in route retracing than in the route repetition task, suggesting that a real environment could compensate for a failing allocentric strategy.     

Facilitating autonomous motivation for smoking cessation.

Physicians used either an autonomy-supportive or a controlling interpersonal style to counsel smokers based on National Cancer Institute guidelines. Physician autonomy support was rated from audiotapes, and patients' perceived competence and autonomous motivation for quitting were self-reported on questionnaires. Validated point prevalences for 6, 12, and 30 months and for continuous cessation were examined. The intervention did not have a direct effect on quit rates; however, structural equation modeling supported the self-determination process model of smoking cessation. The model indicated that the autonomy-supportive intervention was rated as more autonomy supportive, that rated autonomy support predicted autonomous motivation, and that autonomous motivation predicted cessation at all points in time. Perceived competence contributed independent variance to cessation only at 6 months.

Scores on the State-Trait Anxiety Inventory for children in a longitudinal study of pubertal Spanish youth.

Changes in scores on the State-Trait Anxiety Inventory for Children for a sample of 534 pubertal adolescents were longitudinally studied over a period of 4 years. Biological development and other variables were investigated. For the 310 boys, A-trait scores decreased significantly with age. The 224 girls showed significantly higher scores than boys in all years of the study. No significant relationship was found between anxiety and pubertal maturity. The year-to-year persistence in symptomatology of anxiety ranged between 55.6% and 66.1% for girls and between 48.5% and 53.1% for boys. Girls showed bi- and tri-annual persistence between 31% and 50%, and boys between 13% and 27%. Neuroticism scores formed the best predictor of A-trait scores. Symptomatology of anxiety is not transient during early adolescence, so personality may provide a risk indicator in the development of anxiety.     

Why we walk the way we do

By using inverse dynamics and forceplate recordings, this study established the principle of oscillating systems and the influence of gravity and body parameters on the programming of the gait parameters, step frequency and length. Calculation of the ratio of the amplitude of the center of mass (CM) and the center of foot pressure (CP) oscillations yielded an equation and established a biomechanical constant, the natural body frequency (NBF). NBF appears to be an absolute invariant parameter, specific to human standing posture and gait in terrestrial gravity, which influences the relative positions of CM and CP and whose value separates the frequency bands of standing posture from those for gait. This equation was tested by using the experimental paradigm of stepping in place and then used in calculating the magnitude of CM oscillations during gait. The biomechanical analysis of the experimental observations allows one to establish the relationships between body parameters and gravity and the central programming of locomotor parameters.     

Organizational self-evaluation: An emerging frontier for organizational improvement

The authors have been working to improve clients’ institutional performance through a framework for institutional assessment and self-assessment. In this framework, performance is defined in terms of mission fulfillment, efficiency, and ongoing relevance (the extent to which the organization adapts to changing conditions in its environment). The framework implies that certain contextual forces drive performance: the internal capacities and motivation of an organization and its external environment. The article presents the framework as well as case studies of several institutions that are using the framework to assess themselves.     

Convenient fixation location within isolated words of different length and structure

When a word is visually presented in a naming or comparison task in such a way that the eye is initially fixated at different locations within the word, a very strong effect of fixation location is found. The effect appears as a U-shaped curve. Naming time and total fixation time (gaze duration) have a minimum for an initial fixation location between the third and fifth letter of the word (for words that are 5-11 letters long). When initial fixation location deviates from this optimum position, times increase at the surprisingly fast rate of 20-30 ms per letter of deviation. By manipulating the internal lexical structure of the words, we show that at least part of the fixation location effect is caused by mechanisms related to ongoing lexical processing. This is demonstrated by the fact that the fixation location effect takes a different form when the most informative part of a word (as determined by dictionary counts) occurs at the beginning or the end of the word.     

Effects of post-trial administration of naloxone and beta-endorphin on shock-induced fighting in rats

To study the involvement of endogenous opioid peptides in the development of shock-induced fighting, naloxone (2 mg/kg) or beta-endorphin (10 micrograms/kg) was administered subcutaneously immediately after the session and during nine consecutive daily sessions to rats repeatedly exposed to electric shocks. beta-Endorphin blocked the development of shock-induced fighting while naloxone facilitated it but only when shock-induced fighting occurred at a low rate. The effects of beta-endorphin were time dependent since when beta-endorphin was injected 90 min after the shock session instead of immediately after, its impairing effect disappeared. In addition, naloxone blocked the impairment produced by beta-endorphin. Differential postsession treatment of each member of pairs of rats with naloxone and beta-endorphin resulted in a higher probability of rats treated with naloxone to be dominant over rats treated with beta-endorphin in the test situation. These results are discussed in relation with the possible involvement of endogenous opioids in the modulation of the physiological consequences of defensive behavioral responses to shock.
