A social dilemma perspective on recycling

Recent research on social responsibility has largely focused on firms, with only limited research into individual behavior. Recycling is socially responsible behavior which poses a difficult choice for consumers because it benefits society as a whole in the long term but involves a personal cost and does not benefit the individual consumer directly. Previous studies of recycling, however, have only partly explained consumers’ recycling choices. Addressing this gap, this research applied a social dilemma perspective in qualitative and quantitative consumer studies. The findings from the studies demonstrated a positive relationship between a consumer's expectation that others will recycle and his own participation. A social value orientation was found to have a significant moderating effect on this relationship.     

Varying response-reinforcer contiguity in a recycling conjunctive schedule

Three experiments describe the effects of manipulating the frequency of response-reinforcer contiguity in a recycling conjunctive schedule. The schedule arranged that a reinforcer was delivered after 30 s provided at least one response had occurred; otherwise the next cycle started immediately. In Experiment 1, this schedule produced the typical pause–respond–pause pattern, with most responses at mid-interval; and, when a limited number of contiguities between responses and food delivery were added, the pattern became more like the monotonic scallop seen on fixed-interval schedules. In Experiment 2, the schedule was initially presented with an additional contingency that allowed contiguity on every trial. Fixed-interval-like behavior occurred and tended to persist as contiguities were gradually eliminated. In Experiment 3, the recycling conjunctive schedule alternated with a condition in which a large number of contiguities occurred. The pause–respond–pause pattern and fixed-interval-like performance occurred with few or many contiguities, respectively. The results of all three experiments illustrate how contiguity interacts with a small number of other variables to determine performance on interval schedules and illuminate previous findings with fixed-interval and fixed-time schedules.     

Office paper recycling: A function of container proximity

We investigated the effects of proximity of containers on pounds of office paper recycled and not recycled by 25 employees. During a memo and central container condition, one container for recyclable paper was provided; in a memo and local container condition, desktop recycling bins, announced by memo, were successively introduced across administrative, office, and instructional settings using a multiple baseline design. Only 28% of paper was recycled in the central container condition, but when recycling containers were placed in close proximity to participants, 85% to 94% of all recyclable paper was recycled. Follow-up assessments, conducted 1, 2, 3, and 7 months after all settings received local recycling containers, showed that 84% to 98% of paper was recycled. Providing desktop recycling containers was a cost-effective procedure with long-term maintenance and program survival.     

Consumer recycling: An ethical decision‐making process

Although recycling is often experienced as a moral dilemma, studies that systematically approach this issue from an ethical perspective are scarce. Moreover, previous studies have explored recycling by mainly using single ethical constructs, such as moral norms, values or obligations, rarely approaching it as an ethical decision‐making process. Our study takes a more holistic approach and integrates the recycling literature with business ethics theory in order to develop a conceptual model of ethical decision making involved in recycling. The model is based on Jones' issue‐contingent model and its key concept, that is, moral intensity, which we extend by adding altruism as an important personality trait that influences pro‐social behaviour. The data were collected from a sample of 367 adult consumers, representative of the Slovenian population by gender and age. The hypotheses were tested using structural equation modelling. The results of our study confirmed the relationships between three key facets of ethical decision making: moral recognition, moral judgment and moral intention. Higher levels of moral recognition were found to lead to more positive moral judgments, which in turn positively influenced the formation of intentions to recycle. Moreover, moral intensity was found to be a significant predictor of moral recognition and moral judgment, while altruism was found to be a significant predictor of moral recognition. These findings hold important implications for public policy makers and social marketers who have to consider not only the consumer characteristics but also the issue characteristics in seeking to understand and influence consumer recycling.

The aftermath of memory retrieval for recycling visual working memory representations

We examined the aftermath of accessing and retrieving a subset of information stored in visual working memory (VWM)—namely, whether detection of a mismatch between memory and perception can impair the original memory of an item while triggering recognition-induced forgetting for the remaining, untested items. For this purpose, we devised a consecutive-change detection task wherein two successive testing probes were displayed after a single set of memory items. Across two experiments utilizing different memory-testing methods (whole vs. single probe), we observed a reliable pattern of poor performance in change detection for the second test when the first test had exhibited a color change. The impairment after a color change was evident even when the same memory item was repeatedly probed; this suggests that an attention-driven, salient visual change made it difficult to reinstate the previously remembered item. The second change detection, for memory items untested during the first change detection, was also found to be inaccurate, indicating that recognition-induced forgetting had occurred for the unprobed items in VWM. In a third experiment, we conducted a task that involved change detection plus continuous recall, wherein a memory recall task was presented after the change detection task. The analyses of the distributions of recall errors with a probabilistic mixture model revealed that the memory impairments from both visual changes and recognition-induced forgetting are explained better by the stochastic loss of memory items than by their degraded resolution. These results indicate that attention-driven visual change and recognition-induced forgetting jointly influence the “recycling” of VWM representations.     

Brief report: Effects of informational feedback on aluminum can recycling

The impact of informational feedback on the depositing of aluminum cans in recycling receptacles at a medium-sized university was investigated. Informational signs were placed over 20-recycling receptacles in three academic buildings. Each informational sign was placed at eye level, with the number of aluminum cans deposited for recycling during the previous week displayed in red digits. A 65% increase in the number of aluminum cans deposited in recycling receptacles with the informational signs was observed. Furthermore, removal of the informational signs was observed to reliably decrease the number of aluminum cans deposited. These results are discussed in the context of employing feedback to increase environmental protection behaviors.     

Separating response dependency and response-reinforcer contiguity within a recycling conjunctive schedule

A procedure is described which disrupts response-reinforcer contiguity and response dependency and which demonstrates how the location of the response dependency in interval schedules can be regarded as a controlling variable in its own right. Rats' lever pressing produced sucrose on a recycling conjunctive fixed-time 30-second fixed-ratio 1 schedule of reinforcement. Reinforcement occurred only at the end of the fixed-time component on this schedule and only if a response had occurred during that component. This produced a pause-respond-pause pattern during the interreinforcer interval for all animals. When the location of the response dependency was then restricted to a 10-second period in the middle of the fixed-time component, the pattern was accentuated and response rates increased for all animals, while postreinforcement pauses decreased sharply for two animals. When responding was required in the first 10 seconds of the fixed-time component, responding peaked earlier in the interval for all animals. Response rates were slightly below those in the previous conditions, while postreinforcement pauses were between 2 and 6 seconds across animals.     

Facilitating paper recycling: effects of prompts, raffles, and contests

The effects of prompts and reinforcement to promote paper recycling were compared in six university dormitories. For a Prompt condition, residents were urged to recycle paper for ecological reasons via flyers distributed to each room. For a Raffle contingency, residents were given one raffle ticket for every pound of paper brought to a collection center. For a Contest contingency, two dorms were paired and the dorm whose residents delivered the most paper won $15 for its treasury. Contingency awareness was strengthened via a flyer placed under the door of each resident's room. Flyers alone had little effect in increasing paper-recycling behaviors, but the raffle (substantially) and the contest (somewhat) increased the amount of paper brought to a dorm's recycling center. Students whose rooms were closest to the collection center showed the greatest participation. Removal of the reinforcement contingencies resulted in a return to baseline levels.     

Evaluating increased effort for item disposal to improve recycling at a university

An evaluation of increased response effort to dispose of items was conducted to improve recycling at a university. Signs prompting individuals to recycle and notifying them of the location of trash and recycling receptacles were posted in each phase. During the intervention, trashcans were removed from the classrooms, and one large trashcan was available in the hallway next to the recycling receptacles. Results showed that correct recycling increased, and trash left in classrooms increased initially during the second intervention phase before returning to baseline levels.     

Consumer recycling: role of incentives,information, and social class

• More and more communities have instituted recycling programs and consumer recycling is no longer a new fad; it is here to stay. However, consumer commitment to recycling and participation rates have leveled off. Whereas lack of access to recycling facilities was cited as a key inhibitor to participation in the early days of recycling, that is generally not the case anymore. Thus there is an imperative to revisit consumer recycling by focusing on behavioral issues that reflect today's context. In this study we review the past literature and propose a comprehensive model of consumer recycling. We identify two intervention mechanisms – incentives or information – that are believed to increase recycling participation. We, then, describe a longitudinal field experiment to evaluate the relative merits of these intervention programs. We conclude that either intervention program is effective, although informational programs appear to have more long‐term effects than incentive programs. We also create a new measure of social class, one that includes other influential actors' characteristics, and show its relationship to recycling attitudes and behaviors.

Increasing recycling in office environments: The effects of specific, informative cues

We investigated the effects of prompts on the recycling behavior of approximately 217 faculty, staff, and graduate students in two academic departments of a large university. During the intervention, two signs were posted in each department. One sign prompted recycling (posted above the recycling receptacle), and the other sign prompted proper disposal of trash (posted above the trash receptacle). Results of a multiple baseline design across the two departments indicated that the sign prompt increased recycling behavior. Installation of the sign prompts in close proximity to receptacles in Department A resulted in a 54% improvement over baseline. Posting of sign prompts over containers 4 m apart in Department B resulted in a 17% improvement, whereas positioning the signs and receptacles in close proximity resulted in a 29% improvement over baseline.     

Effects of number and location of bins on plastic recycling at a university

The proportion of plastic bottles that consumers placed in appropriate recycling receptacles rather than trash bins was examined across 3 buildings on a university campus. We extended previous research on interventions to increase recycling by controlling the number of recycling receptacles across conditions and by examining receptacle location without the use of posted signs. Manipulating the appearance or number of recycling bins in common areas did not increase recycling. Consumers recycled substantially more plastic bottles when the recycling bins were located in classrooms.     

A review of ideomotor approaches to perception,cognition, action,and language: advancing a cultural recycling hypothesis

The term “cultural recycling” derives from the neuronal recycling hypothesis, which suggests that representations of cultural inventions like written words, Arabic numbers, or tools can occupy brain areas dedicated to other functions. In the present selective review article, we propose a recycling hypothesis for the ideomotor mechanism. The ideomotor approach assumes that motor actions are controlled by the anticipation of the expected perceptual consequences that they aim to generate in the environment. Arguably, such action–perception mechanisms contribute to motor behaviour for human and non-human animals since millions of years. However, recent empirical studies suggest that the ideomotor mechanism can also contribute to word processing, number representation, and arithmetic. For instance, it has been shown that the anticipatory simulation of abstract semantics, like the numerical quantitative value of three items can prime processing of the associated Arabic number “3”. Arabic numbers, words, or tools represent cultural inventions, so that, from a theoretical perspective, we suggest an ideomotor recycling hypothesis for the interaction with such artefacts. In this view, the ideomotor mechanism spreads its influence to other functions beyond motor control, and is recycled to flexibly adapt different human behaviours towards dealing with more abstract concepts.     

Why do salmon go upstream in fresh water from oceans: Evolution of the global recycling of nutrients through higher organisms

The quasi‐homogeneous cold water mass lying deeper than 1000 m below sea level serves as a sink for, and hence is rich in, inorganic nutrients, including nitrates and above all phosphates, which, directly or through numerous food chains, have found their way to the ocean bottom. This cold water mass surfaces during the cold season in temperate zones and permanently in arctic/antarctic zones, which could support extremely rich marine life permitted by relatively low temperatures. Such fruits de mer are predated by rich marine faunas of local and migrating mammals and birds. As for the migrating birds, they breed during the short summer in both circumpolar zones of the earth, to bring the newly acquired biomaterial including inorganic matter to their overwintering sites of the temperate/ subtropical region. Through food chains mainly involving birds and insects, the nutrients accumulated in the deep sea waters would thus be brought back to the land, upwards even to the high mountains. A similar role may be attributed to salmonids and their southern hemisphere counterparts.

In the case of woodland birds, an estimate made in Japan indicates that ca. 10 tons per km2 of insects support the total insectivorous bird lives of the area. This figure may approximately be used as an index of the inorganic nutrients to be returned per annum to the soil through bird droppings and corpses. Using the number of salmonids caught during the peak period of the highly exploitative fishery perpetrated by Japanese fishing boats around 1910 near the mouth of Amur River, I estimate possible biomass contribution to the land from the sea by salmon returning to the upstream of the Amur in wilderness (ca. 6000 tons per annum). According to Arsen'ev (1930), a school of salmons swimming upstream became a victim of active predation by mammals and birds in the mountains. Whereas the total length of the main path of the Amur beyond the junction of Shilka and Onon Rivers is ca. 4000 km, the total contribution of biomass (and hence inorganic material) by salmonid fish to land would amount to, using the above index for birds’ annual predation of insects per unit area, an equivalent of 100 m‐wide zone along streams of a total length of at least 60,000 km, a distance which would cover a good part of smaller tributary currents of the Amur.

The coevolution of nutrient recycling through organism's migration throughout the global ecosystem would be difficult to explain by natural selection, because there cannot be competition for improvement with the unique system of global redistribution of nutrient materials. Also the time scale needed to bring about selection would by far exceed the generation time of organisms involved.
