A new look at sensory attenuation. Action-effect anticipation affects sensitivity, not response bias

The systematic association of an action that a person performs with its sensory effects is thought to attenuate that person's perception of the effect of the action. However, whether learned sensorimotor contingencies truly affect perception, rather than just inducing a response bias, has yet to be determined. The experiment presented in this article comprised two parts: an action-effect association phase and a test phase, during which the actions' perceptual effects were tested. During the association phase, specific actions (left-key and right-key presses) were associated with specific visual effects (tilted Gabor patches). In the test phase, participants' left-key presses and right-key presses triggered the onset of a low-contrast tilted Gabor patch in 50% of trials (no stimulus was presented on the remaining 50% of trials). Participants were required to report the presence or absence of this tilted Gabor patch. Our results showed that participants' sensitivity (d') to the Gabor patches was reduced by 10% when the patches were triggered by the action they had previously been associated with. This finding indicates that a person's action does not induce a response bias (c), but changes the perception (d') of the learned action effect.     

Environmental attitude as a mediator of the relationship between psychological restoration in nature and self-reported ecological behavior

Environmental attitude and ecological behavior were investigated in relation to the use of nature for psychological restoration. Specifically, with survey data from 468 German university students, the role of environmental attitude was investigated as a mediator of the restoration-behavior relationship. Assuming that positive experiences in nature can have a broad influence on environmental attitudes, the New Ecological Paradigm (NEP) scale, an attitudinal measure with broad scope, was adopted. Hierarchical regression analyses indicated partial mediation by environmental concern. The study helps to consolidate the restoration theme in the growing literature on positive motivations for ecological behavior.     

Metacognitive myopia and the overutilization of misleading advice

Previous research on advice taking has explained the failure to exploit collective wisdom in terms of the egocentric underweighting of advice provided by independent others. The present research is concerned with an opposite and more radical source of irrational advice taking, namely, the failure to critically assess the validity of advice due to metacognitive myopia. Participants could use the advice of one or two experts when estimating health risks. They read sketches of the study samples that experts had drawn to estimate conditional probabilities (e.g., of HIV‐given drug addiction). Whether samples were valid or seriously biased, subsequent judgments were strongly affected by any advice (Experiment 1). Uncritical reliance on any advice persisted when participants were sensitized to the contrast of valid and invalid advice in a repeated measures design (Experiment 2), when participants themselves believed advice not to be valid (Experiment 3), and even after full debriefing about invalid advice (Experiment 4). Lay advice exerted a similar influence as expert advice (Experiment 5). Although these provocative results are independent of numeracy and consensus (Experiment 6), they highlight the impact of metacognitive myopia as an impediment of social rationality.     

Satisfaction,loyalty and word of mouth within the customer base of a utility provider: differences between stayers,switchers and referral switchers

Research on satisfaction, loyalty and word of mouth (WOM) behaviour has made considerable progress within recent years, but important aspects remain neglected. In this paper, it is argued that, within the customer base of service providers, certain groups can be identified which differ from each other with regards to these variables. Hypotheses are developed and tested in a sample of 765 clients of a large German energy provider. The results show that recently acquired customers (switchers) differ from long‐term customers (stayers), and that switchers acquired through customer referrals differ from switchers recruited through advertising or direct mail in their satisfaction, loyalty and WOM behaviour. The paper ends with some important implications for management and future research. Copyright © 2004 Henry Stewart Publications Ltd.     

Equality Beyond Needs-Satisfaction: An Empirical Investigation

The moral value of distributive equality constitutes one of the most contentious debates in political philosophy. Following Frankfurt, many philosophers have claimed that the intuitive appeal of equality is illusory and that egalitarian intuitions are fundamentally intuitions about the importance of satisfying basic needs. According to this argument, our intuitions tell us that inequality ceases to matter once a certain threshold has been reached. Despite the widespread appeal to intuitions regarding this issue, few empirical studies have tried to assess whether Frankfurt and his followers are right in claiming the lack of intuitiveness of equality per se. In a series of three experiments, we show that experimental evidence does not allow us to settle the intuitiveness of each theory: laypeople are divided in the consideration of the respective importance of needs and equality. While our results do show that laypeople attach special importance to needs-fulfilment, it also seems that they are divided when it comes to the importance they grant to equality once needs are fulfilled. No theory is unanimously backed by participants, and it seems that, fundamentally, divisions among philosophers reflect deep divisions among people.     

“How old do you feel today at work?” Work-related drivers of subjective age in the workplace

ABSTRACT

Most Western societies face the challenge of steadily ageing workforces. In recent decades, research on ageing has intensively focused on the subjective age concept to understand the challenges and risks of increasingly ageing workforces. Nevertheless, the subjective age construct is subject to several conceptual uncertainties, namely, regarding its stability and potential work-specific drivers of subjective age. We address these limitations by a) investigating the stability of subjective age in a worker sample, and b) identifying work-specific drivers (e.g., negative work events, positive work events, work stress) of subjective age perceptions. Building on social identity and lifespan theories, we test our conceptual assumptions with an online sample of 168 U.S. employees, applying growth curve modelling in a daily diary study over one workweek. Results indicate that subjective age is a mutable construct and varies between- and within-person in the course of a workweek. We identify positive work events and work stress as between-person drivers and negative work events as a within-person driver of subjective age. We discuss theoretical implications of these findings as well as consequences for practitioners.
