Dynamic cognitive control of irrelevant sound:Increased task engagement attenuates semantic auditory distraction
Two experiments investigated reactive top-down cognitive control of the detrimental influence of spoken distractors semantically related to visually-presented words presented for free recall. Experiment 1 demonstrated that an increase in focal task-engagement—promoted experimentally by reducing the perceptual discriminability of the visual target-words—eliminated the disruption by such distracters of veridical recall and also attenuated the erroneous recall of the distracters. A recall instruction that eliminates the requirement for output-monitoring was used in Experiment 2 to investigate whether increased task-engagement shields against distraction through a change in output-monitoring processes (back-end control) or by affecting the processing of the distracters during their presentation (front-end control). Rates of erroneous distracter-recall were much greater than in Experiment 1 but both erroneous distracter-recall and the disruptive effect of distracters on veridical recall were still attenuated under reduced target-word discriminability. Taken together, the results show that task-engagement is under dynamic strategic control and can be modulated to shield against auditory distraction by attenuating distracter-processing at encoding thereby preventing distracters from coming to mind at test
Why People Harm the Environment Although They Try to Treat It Well: An Evolutionary-Cognitive Perspective on Climate Compensation
Anthropogenic climate changes stress the importance of understanding why people harm the environment despite their attempts to behave in climate friendly ways. This paper argues that one reason behind why people do this is that people apply heuristics, originally shaped to handle social exchange, on the issues of environmental impact. Reciprocity and balance in social relations have been fundamental to social cooperation, and thus to survival, and therefore the human brain has become specialized by natural selection to compute and seek this balance. When the same reasoning is applied to environment-related behaviors, people tend to think in terms of a balance between “environmentally friendly” and “harmful” behaviors, and to morally account for the average of these components rather than the sum. This balancing heuristic leads to compensatory green beliefs and negative footprint illusions—the misconceptions that “green” choices can compensate for unsustainable ones. “Eco-guilt” from imbalance in the moral environmental account may promote pro-environmental acts, but also acts that are seemingly pro-environmental but in reality more harmful than doing nothing at all. Strategies for handling problems caused by this cognitive insufficiency are discussed

Effects of labeling a product eco-friendly and genetically modified: A cross-cultural comparison for estimates of taste, willingness to pay and health consequences
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 (especially for health estimates). The roles of individual differences in attitudes, environmental concern and socially desirable responding in relation to the label effects are discussed
Irregular stimulus distribution increases the negative footprint illusion
As a climate change mitigation strategy, environmentally certified ‘green’ buildings with low carbon footprints are becoming more prevalent in the world. An interesting psychological question is how people perceive the carbon footprint of these buildings given their spatial distributions in a given community. Here we examine whether regular distribution (i.e., buildings organized in a block) or irregular distribution (i.e., buildings randomly distributed) influences people's perception of the carbon footprint of the communities. We first replicated the negative footprint illusion, the tendency to estimate a lower carbon footprint of a combined group of environmentally certified green buildings and ordinary conventional buildings, than the carbon footprint of the conventional buildings alone. Importantly, we found that irregular distribution of the buildings increased the magnitude of the negative footprint illusion. Potential applied implications for urban planning of green buildings are discussed

Erroneous and Veridical Recall Are Not Two Sides of the Same Coin: Evidence From Semantic Distraction in Free Recall
Two experiments examined the extent to which erroneous recall blocks veridical recall using, as a vehicle for study, the disruptive impact of distractors that are semantically similar to a list of words presented for free recall. Instructing participants to avoid erroneous recall of to-be-ignored spoken distractors attenuated their recall but this did not influence the disruptive effect of those distractors on veridical recall (Experiment 1). Using an externalised output-editing procedure—whereby participants recalled all items that came to mind and identified those that were erroneous—the usual between-sequence semantic similarity effect on erroneous and veridical recall was replicated but the relationship between the rate of erroneous and veridical recall was weak (Experiment 2). The results suggest that forgetting is not due to veridical recall being blocked by similar events
