- The addition of environmentally friendly items to conventional items sometimes leads people to believe that the carbon footprint of the entire set decreases rather than increases. This negative footprint illusion is supposedly underpinned by an averaging bias: people base environmental impact estimates not on the total impact of items but on their average. Here, we found that the illusion's magnitude increased with the addition of a greater number of "green" items when the number of conventional items remained constant (Studies 1 and 2), supporting the averaging-bias account. We challenged this account by testing what happens when the number of items in the conventional and "green" categories vary while holding the ratio between the two categories constant (Study 3). At odds with the averaging-bias account, the magnitude of the illusion increased as the category size increased, revealing a category-size bias, and raising questions about the interplay between these biases in the illusion.

Disruption of writing processes by the semanticity of background speech

- Previous studies have noted that writing processes are impaired by task-irrelevant background sound. However, what makes sound distracting to writing processes has remained unaddressed. The experiment reported here investigated whether the semanticity of irrelevant speech contributes to disruption of writing processes beyond the acoustic properties of the sound. The participants wrote stories against a background of normal speech, spectrally-rotated speech (i. e., a meaningless sound with marked acoustic resemblance to speech) or silence. Normal speech impaired quantitative (e. g., number of characters produced) and qualitative/ semantic (e. g., uncorrected typing errors, proposition generation) aspects of the written material, in comparison with the other two sound conditions, and it increased the duration of pauses between words. No difference was found between the silent and the rotated-speech condition. These results suggest that writing is susceptible to disruption from the semanticity of speech but not especially susceptible to disruption from the acoustic properties of speech.

Glorification of eco-labeled objects : An effect of intrinsic or social desirability?
- 2015
-
Konferensbidrag (refereegranskat)abstract
- Environmentally friendly consumables and products are often perceived as superior to their conventional counterparts. The reason for this, at least in part, is that people tend to glorify eco-labeled objects. For example, people prefer the taste of coffee called “eco-friendly” in comparison with another cup of coffee called “conventional”, even when the two cups of coffee are actually identical and merely named differently. What is the underlying mechanism of this eco-label effect? Do people report superior evaluations of eco-labeled products for intrinsic reasons or because they think this attitude is approved by others (a social desirability mechanism)? In two experiments, the participants’ concerns with social desirability were manipulated by telling them that their taste judgments of consumables were monitored by others. The eco-label effect was just as strong in the high social desirability concerns condition as in a control condition (Experiments 1 and 2). However, the eco-label effect was stronger in magnitude for participants who were told that consumers are morally responsible for the environmental consequences of their consumer behavior (Experiment 2). Taken together, the eco-label effect appears to be caused by intrinsic desirability processes, not by social desirability processes.

Short-term memory effects of eco-labeling: Evidence from the perceived environmental friendliness of sequential consumer behavior
- 2024

Tidskriftsartikel (refereegranskat)abstract
- Can memory of eco-labeling bias how consumption is perceived and influence subsequent consumer decisions? We report three experiments showing that the perceived environmental friendliness of simulated shopping sequences is disproportionately influenced by what happens at the end of the sequence. For example, sequences that ended with a high carbon footprint item were perceived as less environmentally friendly than other sequences with the same content but with items in different order—a recency effect (Experiments 1–3). Judgments depended more on how often environmentally significant items were purchased than on the quantity of those items (Experiment 2). Furthermore, after completing a shopping sequence that was perceived as relatively harmful to the environment, participants were more prone to select a comparably expensive eco-labeled item over a cheaper but less environmentally friendly item in subsequent purchase decisions—a spillover effect (Experiment 3). The results stress the role of memory in environmentally significant consumer behavior.

Irrelevant changing-state vibrotactile stimuli disrupt verbal serial recall: implications for theories of interference in short-term memory
- 2024

- What causes interference in short-term memory? We report the novel finding that immediate memory for visually-presented verbal items is sensitive to disruption from task-irrelevant vibrotactile stimuli. Specifically, short-term memory for a visual sequence is disrupted by a concurrently presented sequence of vibrations, but only when the vibrotactile sequence entails change (when the sequence “jumps” between the two hands). The impact on visual-verbal serial recall was similar in magnitude to that for auditory stimuli (Experiment 1). Performance of the missing item task, requiring recall of item-identity rather than item-order, was unaffected by changing-state vibrotactile stimuli (Experiment 2), as with changing-state auditory stimuli. Moreover, the predictability of the changing-state sequence did not modulate the magnitude of the effect, arguing against an attention-capture conceptualisation (Experiment 3). Results support the view that interference in short-term memory is produced by conflict between incompatible, amodal serial-ordering processes (interference-by-process) rather than interference between similar representational codes (interference-by-content).

Individual differences in distractibility : an update and a model
- 2014
-
Ingår i: PsyCh Journal. - : Wiley. - 2046-0252 .- 2046-0260. ; 3:1, s. 42-57
-
Tidskriftsartikel (refereegranskat)abstract
- This paper reviews the current literature on individual differences in susceptibility to the effects of background sound on visual-verbal task performance. A large body of evidence suggests that individual differences in working memory capacity (WMC) underpin individual differences in susceptibility to auditory distraction in most tasks and contexts. Specifically, high WMC is associated with a more steadfast locus of attention (thus overruling the call for attention that background noise may evoke) and a more constrained auditory-sensory gating (i.e., less processing of the background sound). The relation between WMC and distractibility is a general framework that may also explain distractibility differences between populations that differ along variables that covary with WMC (such as age, developmental disorders, and personality traits). A neurocognitive task-engagement/distraction trade-off (TEDTOFF) model that summarizes current knowledge is outlined and directions for future research are proposed.

All's eco‐friendly that ends eco‐friendly: Short‐term memory effects in carbon footprint estimates of temporal item sequences
- 2024
-
Ingår i: Applied Cognitive Psychology. - : John Wiley & Sons. - 0888-4080 .- 1099-0720. ; 38:3

Tidskriftsartikel (refereegranskat)abstract
- When people estimate the summative carbon footprint of a sequence of events, how are the individual events integrated? In three experiments, we found that summative carbon footprint judgments of item sequences are disproportionately influenced by items at the end of the sequence in comparison with those at the beginning—a recency effect. When, for example, sequences ended with a low carbon footprint item, they were assigned a lower carbon footprint than corresponding sequences with an identical content but different item order. The results also revealed that a green peak (presenting many low carbon footprint items at once) had a relatively large effect on estimates when the peak was contextually distinct from other items in terms of its valence. The results are consistent with an account within which distinctiveness of representations within short-term memory differentially influences decision-making and suggest that memory processes bias the perceived environmental footprint of temporally separated instances.
