Abstract [en]

Climate change is strongly linked to human behavior and technologies, and many of the barriers to sustainable behavior are rather psychological than technological. More sustainable technologies and food products have been introduced to combat climate change, most often labeled with morally loaded labels such as “organic” or “environmentally friendly”. The purpose of this thesis was, first, to gain knowledge into the psychological consequences of the introduction of eco-friendly technologies in the built environment, specifically how labeling these products “eco-friendly” influences perception and performance; secondly, to identify underlying psychological mechanisms and limits of this eco-label effect. Study 1 showed that participants generally prefer the taste of consumables labeled eco-friendly compared to conventional labeled alternatives, but the study also found that the label-effect is limited to certain products and certain judgmental dimensions. Results in this study also showed that people believe that eco-labeled products have positive effects on mental abilities. In Study 2 and 3, the focus was to study the effects of eco-labeling in the built environment on performance in cognitively demanding tasks, such as color discrimination and proofreading. At this point, the eco-label effect had been shown across a wide range of products like food, water, and office technologies, and been generalized to a wide range of judgmental dimensions and behaviors (i.e. taste, nutrition health benefits, comfortableness, and mental performance). In Study 4, results showed that eco-labeling can have effects also on behavior that arguably have very little to do with the labeling itself, by showing that social perception of photographed persons can also depend on the labeling of desktop lamps. A consistent finding across the studies was also that individual differences in environmental concern modulated the magnitude of the effect. The magnitude was larger in people with higher concern for the environment.

Abstract [sv]

Klimatförändringen har en stark koppling till mänskligt beteenden och teknologiska lösningar. En stor del av det som hindrar den hållbar utveckling är mer psykologiska än tekniska till sin natur. Många hållbara tekniska lösningar och livsmedelsprodukter har införts för att bekämpa klimatförändringar, ofta märkta med moraliskt laddade etiketter som "ekologiska" eller "miljövänliga". Syftet med den här avhandlingen var att bringa mer kunskap om de psykologiska konsekvenserna av införandet av miljövänliga teknologiska lösningar i den byggda miljön, mer specifikt, hur perception och prestation påverkas av att märka dessa produkter som miljövänliga. Ytterligare var syftet att identifiera underliggande psykologiska mekanismer och begränsningar gällande eco-label effekten. Studie 1 visar att deltagare oftast föredrar smaken av produkter som är märkta miljövänliga jämfört med konventionellt märkta alternativ, men studien har också fastställt att eco-label effekten är begränsad till vissa produkter och bedömningsdimensioner. Resultatet i Studie 1 visade också att människor tror att miljömärkta produkter har positiva effekter på mentala förmågor. I Studie 2 och 3 var fokus på att studera effekterna av miljömärkning i den byggda miljön på prestationer i kognitiva uppgifter, såsom färgdiskriminering och korrekturläsning. Effekten av miljömärkning har visats gälla för ett brett spektrum av produkter som mat, vatten och kontorsmaterial och kan generaliseras till ett brett spektrum av bedömningsdimensioner och beteenden (dvs. smak, hälsofördelar, bekvämlighet och mentala prestationer). I Studie 4 framgår det också att miljömärkning kan ha effekt på beteende som har mycket lite att göra med miljömärkningen i sig, genom att visa att sociala bedömningar av fotograferade personer också kan bero på etikettering av skrivbordslampor. Konsekvent över studierna var också att individuella skillnader i miljöoro modulerade effektens storlek. Effekten var störst för de med störst oro för miljön.

Abstract [en]

As the demand for eco-friendly food—produced without pesticides and environmentally harmful chemicals—increases, the need to develop genetically modified (GM) organisms that are more resistant to parasites and other environmental crop threats may increase. Because of this, products labeled both “eco-friendly” and “genetically modified” could become commonly available on the market. In this paper, we explore—in a Swedish and a UK sample—the consequences of combining eco-labeling and GM-labeling to judgments of taste, health consequences and willingness to pay for raisins. Participants tasted and evaluated four categories of raisins (eco-labeled and GM-labeled; eco-labeled; GM-labeled; and neither eco-labeled nor GM-labeled). The results suggest that there is a cost associated with adding a GM-label to an eco-labeled product: The GM-label removes the psychological benefits of the eco-label. This negative effect of the GM-label was larger among Swedish participants in comparison with UK participants, because the magnitude of the positive effect of the eco-label was larger in the Swedish sample and, hence, the negative effects of the GM-label became more pronounced. The pattern was somewhat different depending on judgmental dimension. The cost associated with adding a GM-label was larger in estimates of taste and health than in estimates of willingness to pay, at least for the Swedish sample. The roles of individual differences in attitudes, environmental concern and socially desirable responding in relation to the label effects are discussed.

Abstract [en]

Visiting or viewing nature environments can have restorative psychological effects, while exposure to the built environment typically has less positive effects. A classic view is that this difference in restorative potential of nature and built environments depends on differences in the intrinsic characteristics of the stimuli. In addition, an evolutionary account is often assumed whereby restoration is believed to be a hardwired response to nature’s stimulus-features. Here, we propose the novel hypothesis that the restorative effects of a stimulus do not entirely depend on the stimulus-features per se, but also on the meaning that people assign to the stimulus. Participants conducted cognitively demanding tests prior to and after a brief pause. During the pause, the participants were exposed to an ambiguous sound consisting of pink noise with white noise interspersed. Participants in the “nature sound-source condition” were told that the sound originated from a nature scene with a waterfall; participants in the “industrial sound-source condition” were told that the sound originated from an industrial environment with machinery; and participants in the “control condition” were told nothing about the sound origin. Self-reported mental exhaustion showed that participants in the nature sound-source condition were more psychologically restored after the pause than participants in the industrial sound-source condition. One potential interpretation of the results is that restoration from nature experiences depends on learned, positive associations with nature; not only on hardwired responses shaped by evolution.

Abstract [en]

People tend to idealize eco-labeled products, but can eco-labeling have consequences for performance? To address this question, 48 university students were asked to undertake a color discrimination task adjacent to a desktop lamp that was either labeled “environmentally friendly” or “conventional” (although they were identical). The light of the lamp labeled “environmentally friendly” was rated as more comfortable. Notably, task performance was also better when the lamp was labeled “environmentally friendly”. Individual differences in environmental concern, but not pro-environmental consumer behavior and social desirability indexes, were related to the magnitude of the eco-label effect on performance. Whilst some previous studies have shown similar placebo-like effects of eco-labels on subjective ratings, this is the first study to show an eco-label effect for artifacts in the built environment on performance, and the first study to relate this effect to environmental concern. Psychological mechanisms that may underpin the eco-label effects are discussed.

Abstract [en]

Consumers believe that “eco-labeled” products taste better, which, at least in part, may be an effect of the label. The purpose of the current series of experiments was to examine some mechanisms and limits of this eco-label effect. In Experiment 1, an eco-label effect of similar magnitude was found for taste ratings of both conventional and organic bananas. Experiment 2 showed eco-label effects for a wider range of judgmental dimensions (i.e., health, calories, vitamins/minerals, mental performance, and willingness to pay) and the effect was about the same in magnitude for judgments of grapes and raisins. Experiment 3, with water as the tasted product, found no eco-label effect on judgments of taste, calories and vitamins/minerals, but an effect on willingness to pay, judgments of health benefits and judgments of mental performance benefits. Experiments 2 and 3 also included questionnaires on social desirability traits, schizotypal traits and pro-environmental consumer traits. The last was the strongest predictor of the eco-label effect amongst the three. In all, the eco-label effect is a robust phenomenon, but depends on interactions between product type and judgmental dimension. Implications for several accounts of the effect are discussed.

Abstract [en]

This article reports 2 experiments that examine techniques to shield against the potentially disruptive effects of task-irrelevant background speech on proofreading. The participants searched for errors in texts that were either normal (i.e., written in Times New Roman font) or altered (i.e., presented either in Haettenschweiler font or in Times New Roman but masked by visual noise) in 2 sound conditions: a silent condition and a condition with background speech. Proofreading for semantic/contextual errors was impaired by speech, but only when the text was normal. This effect of speech was completely abolished when the text was written in an altered font (Experiment 1) or when it was masked by visual noise (Experiment 2). There was no functional difference between the 2 ways to alter the text with regard to the way the manipulations influenced the effects of background speech on proofreading. The results indicate that increased task demands, which lead to greater focal-task engagement, may shield against the distracting effects of background speech on proofreading.

Abstract [en]

Two experiments will be presented which assessed free recall of spoken words in Swedish (native tongue) and in English heard under different signal-to-noise ratios (SNR: +3 and +12 dB), and different reverberation times (RT: 0.3 and 1.2 s). All participants encountered these eight experimental conditions (Language*SNR*RT). The first experiment was run with college student (N=48), who were run individually. In the second experiment children in grade 4 (10-11 years, N=72) took part and they were run as a group in their regular classrooms.

Twelve wordlists in English and twelve wordlists in Swedish were generated. The words were chosen according to their ranks in category norms for the two languages. The number of words in each list was 12 for the college group and 8 for children in Grade 4. The 2 x 12 wordlists were presented in counter balanced presentation orders in three blocks (Blocks). To compare primacy and recency effects the word lists were divided into three parts (p3rd). After each wordlist the participants typed in or wrote down the words they could recall.

The basic hypotheses for the recall of the words were that working memory would be overloaded when the SNR was low and the RT was long, and that SNR and RT would interact with each other, with Language and with Study (Grade4/College). The analyses suggest that for both groups there were expected effects of language and of SNR, but the effect of RT was smaller and only showed up in interactions.
