Inspired by the principles used to market physical products, campaigns to promote pro-environmental behaviour have increasingly emphasized self-interested (for example, economic) reasons for engaging with a self-transcendent cause (that is, protecting the environment) 1,2 . Yet, psychological evidence about values and behaviour suggests that giving self-interested reasons, rather than self-transcending reasons, to carry out a self-transcending action should be ineffective at increasing self-transcending behaviour more generally 3,4 . In other words, such a campaign may fail to cause spillover, or an increase in other, different environmental behaviours 5 . Here we show that recycling rates are dependent on the information participants receive about a separate environmental behaviour, car-sharing (carpooling in the USA). In two experiments, we found that recycling was significantly higher than control when participants received environmental information about car-sharing, but was no different from control when they received financial information or (in experiment 2) received both financial and environmental information. Our results suggest that, congruent with value theory, positive spillover from one environmental message to another behaviour (car-sharing to recycling) may occur primarily when self-transcending reasons alone are made salient.When attempting to persuade people to adopt proenvironmental behaviour, it seems intuitive to persuade them that it is in their own interest. Indeed, many campaigns emphasize financial reasons to change environmental behaviour. For example, the website for the UK's Act on CO 2 campaign points to money-saving features of energy-reducing behaviours and appliances 1 . Similarly, the USA's Environmental Protection Agency often mentions the financial savings associated with the actions it recommends 2 . However, campaigners have recently raised the possibility that this tactic may reduce the scope for positive spillover in pro-environmental behaviours 5 . Spillover refers to the likelihood that the encouragement of one environmental behaviour (for example, through a campaign), or its performance, will lead to the performance of other pro-environmental behaviours in the future. Thøgersen and Crompton argued that financial incentives might actually decrease the likelihood of positive spillover; that is, such incentives may make people less likely to carry out environmental actions in general 5 .The theoretical basis for this concern comes from extant psychological models of values and goals 3,4 -in particular, Schwartz's model of social values 4 . In this model, values that promote selfinterest or self-enhancement (for example, power, wealth) tend to conflict with values that transcend personal interest to consider the welfare of the community (for example, helpfulness, protecting the environment), whereas values that follow intellectual and emotional interests in uncertain directions (for example, creativity, freedom) tend to conflict with values that emphasize protecting
Two experiments involving a total of 220 subjects are reported. The experiments document that "stroking" a false hand with the bright beam of light from a laser pointer can produce tactile and thermal sensations when the hand can be seen as one's own. Overall, 66% of subjects reported somatic sensations from the light. Felt hand location was recalibrated toward the location of the false hand for those subjects who felt the light. Moreover, the proprioceptive recalibration from the laser experience was comparable to that produced by actual coordinated brushing of the false hand and of the unseen real hand after 2 min of stimulation. The illusion may be experienced on one's real hand as well. The results are discussed in terms of multisensory integration.
The precision control of nanoscale materials remains a challenge for the study of nanostructure-performance relationships. Persistent micelle templates (PMT) are a kinetic-controlled self-assembly approach that decouples pore and wall control. Here, block copolymer surfactants form persistent micelles that maintain constant template size as material precursors are added, despite the shifting equilibrium dimensions. Earlier PMT demonstrations were based upon solvent mixtures where kinetic rates were adjusted with the amount of water cosolvent. This approach is however limited because ever-higher water contents can lead to secondary porosity within the material walls. Herein, we report an improved method to regulate the PMT kinetics via the majority solvent. This enables a new avenue for the expansion of the PMT window to realize templated materials with a greater extent of tunability. In addition, we report a new small-angle X-ray scattering (SAXS)-based log-log analysis method to independently test the micelle-templated series for consistency with the expected lattice expansion with an increasing material:template ratio. The PMT window identified by the log-log analysis of the SAXS data agreed well with independent scanning electron microscopy measurements. The combination of improved micelle control with solvent selection along with SAXS validation will accelerate the development of a myriad of nanomaterial applications.
