Nanomaterials and the environmental risk: is there some room left for ethics and law?

How legitimate may be the concern posed by the nanotechnologies for health and environment,this effort for reaching a better knowledge of the biotoxicity of nanomaterials is not enough. As Pr Didier Sicard noted, we believe that the ethical reflection should not be the good conscience that may help science in getting rid of social fears. But the ethical reflection is there also to discuss taboo issues in the perspective of a better societal understanding.     

Who cares about ecology? Personality and sex differences in environmental concern1

This study was designed to identify personality factors that underlie concern for ecological-environmental problems. High and low environmental-concern individuals were given the California Psychological Inventory and were found to differ significantly on many subscales. A factor analysis of the CPI data produced four factors which closely paralleled previous CPI research findings. In conjunction with this analysis, four factorially derived scores were obtained for each individual. Comparison of high and low environmental-concern individuals' factorially derived scores showed high environmental-concern persons as having stronger value orientation, person orientation, and ethical-conscientiousness, but not differing from low environmental-concern individuals in terms of independence of thought or action. Further, high environmental-concern females were found to be significantly more extraverted, “leader-types” than low environmental-concern females; while the opposite relation was obtained for males. Thus, it appears that men and women become involved with the environmental movement for different reasons. Finally, additional implications of the involvement of basic psychological individual differences in determining ecological-environmental concern were discussed.     

Rebellious teens? Genetic and environmental influences on the social attitudes of adolescents

Genetic and environmental influences in social attitudes were investigated in adopted and nonadopted children (N = 654) and their biological and adoptive relatives in the Colorado Adoption Project. Conservatism and religious attitudes were measured in the children annually from ages 12 to 15 and in the parents during the 12-year-old visit. Multivariate genetic model fitting indicated that both conservatism and religious attitudes are strongly influenced by shared-family environmental factors throughout adolescence. In contrast to previous findings from twin studies, which suggest that genetic influence on social attitudes does not emerge until adulthood, the present study detected significant genetic influence in conservatism as early as age 12. There was no evidence of genetic influence, however, on religious attitudes during adolescence.     

The creative thinking,environmental frustration,and self‐concept of left‐ and right‐handers

Abstract:

Left‐ (n = 12) and right‐handed (n = 12) college students were compared on creative thinking, environmental frustration, and self‐concept. It was hypothesized that because left‐handers regularly encounter equipment designed for right hand use, these individuals must use creative thinking to successfully interact with the environment. Results indicated that on the Environmental Frustration Questionnaire, left‐handers indicated significantly greater frustration with two of the six categories of objects, namely household tools (p < .005) and classroom desks (p < .005). On the Verbal and Figural Forms of the Torrance Tests of Creative Thinking, lefthanders scored significantly higher on the figural elaboration measure (p < .05). Finally, the hypothesis that handedness plays a larger role in the self‐concept of left‐handers than right‐handers was confirmed. Left‐handers were significantly more likely than right‐handers to mention their handedness when asked to describe themselves (p < .05).     

Appreciation of nature and appreciation of environmental protection: How stable are these attitudes and which comes first?

IntroductionAttitude toward nature and attitude toward environmental protection are two separate but correlated attitudes. Little is known about the two attitudes’ stability/volatility over time, despite the practical value of such knowledge.Objectives & methodUsing longitudinal survey data from 251 adults in a cross-lagged structural equation model, we assessed the degree of spontaneous (i.e., unprompted) change in the two attitudes. We also considered whether such change could provide evidence regarding causal direction; causation could go in either of two directions between the two attitudes, or it could even be bi-directional.ResultsWe corroborated the substantive connection between attitude toward nature and attitude toward environmental protection; however, the absence of change in the attitudes despite the passage of two years disallows reliable statements about causal direction.ConclusionIt is possible to protect the environment by encouraging appreciation of nature, but change in attitude toward nature and attitude toward environmental protection may be difficult to achieve with mature individuals.     

Are modern health worries associated with somatosensory amplification,environmental attribution style,and commitment to complementary and alternative medicine?

Relationship among modern health worries (MHWs), somatosensory amplification (SSA), and attributional styles was investigated in a cross-sectional questionnaire study. A total of 99 university students, 104 patients visiting their General Practitioners, and 102 future alternative therapists completed questionnaires assessing MHWs, SSA, negative affect (NA), and psychological, somatic and normalizing (environmental) attribution styles. Significant correlation between SSA and MHWs was found in all three samples. MHWs and psychological attribution style were significantly associated with Complementary and Alternative Medicine (CAM)-orientation in the regression equation even after controlling for SSA, NA, and sociodemographic variables. MHWs were independent from any attribution styles in the student and patient samples, while significant correlations with all three styles were found in the CAM group. Previously described association between MHWs and SSA was replicated in three different samples. The connection between MHWs and CAM preference seems to be independent from SSA, NA or any particular attribution style.     

Must egocentric and environmental frames of reference be aligned to produce spatial S-R compatibility effects?

Four experiments were conducted to determine the effects of misaligning egocentric and environmental frames of reference on spatial S-R compatibility effects. In Experiments 1 and 3, subjects looked at two lights that were aligned horizontally, one each on either side of the body midline. They held their head upright or tilted 90 degrees to the left or right. In the upright condition the hands were uncrossed and rested opposite the lights (frames of reference aligned), whereas in the head tilt condition the hands were either crossed or uncrossed but positioned perpendicular to the lights (frames of reference not aligned). Manual choice reaction times to the lights produced spatial S-R compatibility effects that were as large when the frames of reference were aligned as when they were not. In Experiments 2 and 4, which also used upright and tilted conditions, we found generally similar results when the lights were displayed vertically and the hands disposed horizontally. The results indicate that under conditions of head rotation and with stimulus and response arrays perpendicular to each other, spatial S-R compatibility effects still occur. By taking into account both frames of reference, the subject classifies the stimuli as left or right whether they are horizontally or vertically disposed and maps them onto the responding hand, thereby producing the observed compatibility effects.     

Specificity of auditory implicit and explicit memory: Is perceptual priming for environmental sounds exemplar specific?

Previous research (Stuart & Jones, 1995) has suggested that identification of environmental sounds may be mediated by abstract sound recognition units. This article reports the results of four repetition priming experiments that find evidence to the contrary. Participants attempted to identify environmental sounds from the initial sound stems (Experiments 1 and 2) or when the sounds were embedded in white noise (Experiments 3 and 4). Repetition of an identical exemplar sound led to more priming than did exposure to a different exemplar, provided that the perceptual difference between the two different exemplars was sufficiently large. Such an exemplar specificity effect was independent of the depth of prior encoding. A similar exemplar specificity effect was also found in explicit stem-cued recall (Experiments 1 and 2) and recognition (Experiment 3). Depth of encoding dissociated performance on tests of repetition priming and explicit memory. These results suggest that a significant amount of specific information is remembered, both implicitly and explicitly, to characterize individual exemplars of a sound category.     

Orienting in virtual environments: How are surface features and environmental geometry weighted in an orientation task?

We investigated how human adults orient in enclosed virtual environments, when discrete landmark information is not available and participants have to rely on geometric and featural information on the environmental surfaces. In contrast to earlier studies, where, for women, the featural information from discrete landmarks overshadowed the encoding of the geometric information, Experiment 1 showed that when featural information is conjoined with the environmental surfaces, men and women encoded both types of information. Experiment 2 showed that, although both types of information are encoded, performance in locating a goal position is better if it is close to a geometrically or featurally distinct location. Furthermore, although features are relied upon more strongly than geometry, initial experience with an environment influences the relative weighting of featural and geometric cues. Taken together, these results show that human adults use a flexible strategy for encoding spatial information.     

The psychology of environmental concern—some Australian data

An attempt is made to find out what psychological traits (if any) are characteristic of the environmentalism supporter in the community at large. In an Australia-wide mail survey, ‘environmentalists’ were found to be consumer-conscious, anti-authoritarian, anti-Australia, less interested in personal ‘success’, anti-fashion, counter-culturally oriented and hedonistic. All except the first were however very weak tendencies. They were found to be equally likely to go either way on social conservatism, economic conservatism, sociability and misanthropy.     

Implementation intentions for physical activity in supportive and unsupportive environmental conditions: An experimental examination of intention–behavior consistency

The primary objective of this investigation was to examine the joint influences of intention strength, executive control resources (ECRs) and implementation intentions on physical activity performance in differentially supportive environmental conditions. In two studies, participants were randomly assigned to implementation intentions or control conditions. Individual differences in ECRs, intention strength and physical activity behavior were measured at baseline in the laboratory; follow-up physical activity was measured via an online questionnaire 7 days after the baseline laboratory session. Study 1 was conducted under activity-supportive environmental conditions (i.e., warm weather, little precipitation), whereas Study 2 was conducted under non-supportive environmental conditions (i.e., cold weather, moderate precipitation). In Study 1, a two-way interaction between ECR and intention strength was observed, such that those with relatively stronger ECR demonstrated stronger intention–behavior relationships than those with relatively weaker ECR; this effect was invariant across experimental conditions. In Study 2, a significant 3-way interaction was observed, such that those with lower ECRs showed greater intention–behavior correspondence in the experimental group compared to the control. Together these findings suggest that the beneficial effects of implementation intentions on intention–behavior correspondence for physical activity may be more potent under challenging environmental conditions, and that they may be of special benefit for those with initially low ECRs.     

Helping to reduce fights before flights: How environmental stressors in organizations shape customer emotions and customer–employee interactions

Previous examinations of environmental stressors in organizations have mostly emphasized their dysfunctional effects on individuals’ emotions and behaviors. Extending this work by drawing from the social functional perspective on emotion, we propose that customers’ negative emotional responses to environmental stressors in organizations can exert both dysfunctional and functional effects on customer–employee interactions. Specifically, we theorize that situational and physiological forms of environmental stressors can be dysfunctional by incurring customer anger, precipitating customer aggression, and diminishing employee helpfulness. We further theorize that situational relative to physiological stressors can exert functional effects in inducing customer fear that elicits empathy and helpfulness from employees. We test our model via an archival, observational, and critical incident yoked experimental study set in the airport context. This research contributes to stress theory and its organizational application by integrating theory from the social functional approach to emotion with appraisal-based theories of stress in organizations.     

The influence of environmental context in interpersonal observation–execution

Cyclical upper-limb movements involuntarily deviate from a primary movement direction when the actor concurrently observes incongruent biological motion. We examined whether environmental context influences such motor interference during interpersonal observation–execution. Participants executed continuous horizontal arm movements while observing congruent horizontal or incongruent curvilinear biological movements with or without the presence of an object positioned as an obstacle or distractor. When participants were observing a curvilinear movement, an object located within the movement space became an obstacle, and, thus, the curvilinear trajectory was essential to reach into horizontal space. When acting as a distractor, or with no object, the curvilinear trajectory was no longer essential. For observing horizontal movements, objects were located at the same relative locations as in the curvilinear movement condition. We found greater involuntary movement deviation when observing curvilinear than horizontal movements. Also, there was an influence of context only when observing horizontal movements, with greater deviation exhibited in the presence of a large obstacle. These findings suggest that the influence of environmental context is underpinned by the (mis-)matching of observed and executed actions as incongruent biological motion is primarily coded via bottom-up sensorimotor processes, whilst the congruent condition incorporates surrounding environmental features to modulate the bottom-up sensorimotor processes.     

Size scaling: retinal or environmental frame of reference?

Previous studies have reported that when subjects are presented with two forms in a same-different task, their reaction times increase with the size ratio. This suggests a "mental scaling" transformation analogous to the "mental rotation" used to compensate for differently oriented forms in similar tasks. However, since the stimuli were presented in isolation, retinal and environmental size ratios were confounded. The present study varied both retinal and environmental size ratios in a same-different simultaneous matching task. In one experiment, random forms were placed at different distances along a textured hallway. A second experiment varied the monocular size information: In one condition the forms were displayed in a textured hallway; a second condition added cast shadows; and a third condition displayed the forms against a frontal wall of indeterminate distance. The results suggest that environmental size is determined prior to mental scaling and form matching.     

A dynamic objective–subjective structure for forest management focusing on environmental issues

In this paper a decision-making process is applied to a Chilean forestry firm that must deal with a host of environmental variables as well as profit making. At the core of this process is a ‘dynamic objective–subjective structure’ founded on the approach that decision making is about comprehending the preferences of the various parties involved and expanding the set of alternatives open to the decision makers. This is in contrast to many models that aim at finding the ‘best alternative’ and to decision analysis approaches that focus on presenting preferences via value functions. The paper describes in chronological order, following the sessions of a decision-making process, how the various components of the structure emerged. In doing so it demonstrates how the process led to an understanding of the real effects of dealing with the environment and how comprehending the preferences led to the introduction of new decision variables.

Improving memory after environmental context change: A strategy of “preinstatement”

A change in environmental context between study and test can produce detrimental effects on memory. For instance, when a change in the environment occurs after an event, memory for the event declines. However, the negative effects of context change can be eliminated when participants are provided with contextual cues. Here, we report that, as predicted by the Lehman–Malmberg model (Lehman & Malmberg Journal of Experimental Psychology: Learning, Memory, and Cognition 35(4):970, 2009, Psychological Review, 2012), participants can overcome a change in the environment by recalling the future test environment while studying, a strategy referred to as preinstatement.
