Abstract [en]

In this paper we argue that unsustainable behaviors often stem from a common averaging bias when people estimate the environmental impact of a set of environmentally friendly and less friendly objects or actions. In Experiment 1, we show that people believe that the total carbon footprint of a category of items (a community of buildings in this case) is lower, rather than higher, when environmentally friendly (“green” buildings) items are added to the category, a negative footprint illusion. Experiment 2 showed  that the carbon footprint estimate assigned to a category with a mix of environmentally friendly and less friendly objects (“green” and conventional  buildings) is the average of its subsets (the “green” buildings and the  conventional buildings, respectively), an averaging bias. A similar averaging  process may underpin estimates of the environmental impact of people's own actions, explaining why people believe that environmentally friendly actions can compensate for less friendly actions.

Abstract [en]

Differences in the impact of irrelevant sound on recall performance in children (aged 7-9 years old; N = 89) compared to adults (aged 18-22 years old; N = 89) were examined. Tasks that required serial rehearsal (serial and probed-order recall tasks) were contrasted with one that did not (the missing-item task) in the presence of irrelevant sound that was either steady-state (a repeated speech token), changing-state (two alternating speech tokens) and, for the first time with a child sample, could also contain a deviant token (a male-voice token embedded in a sequence otherwise spoken in a female voice). Participants either completed tasks in which the to-be-remembered list-length was adjusted to individual digit span or was fixed at one item greater than the average span we observed for the age-group. The disruptive effects of irrelevant sound did not vary across the two methods of determining list-length. We found that tasks encouraging serial rehearsal were especially affected by changing-state sequences for both age-groups (i.e., the changing-state effect) and there were no group differences in relation to this effect. In contrast, disruption by a deviant sound—generally assumed to be the result of attentional diversion—was evident among children in all three tasks while adults were less susceptible to this effect. This pattern of results suggests that developmental differences in distraction are due to differences in attentional control rather than serial rehearsal efficiency.

Abstract [en]

Environments with high temperatures and under steady conditions are perceived poor. The introduction of airflow variations in such environments improves the perception. However the risk of draught is high and to avoid this, variations in high velocity supply is used. This method is far more energy efficient than cooling the entire space as only the occupants are cooled. This paper discusses two studies on occupant cooling conducted at the University of Gävle.  The experiments were performed in a full scale mockup classroom and a total of 85 students participated. In Study 1, students sat in a classroom for about 60 minutes in one of two heat conditions: 20 and 25 º C. In Study 2, the indoor parameters of 25 º C were maintained but airflow variation in the sitting zone was manipulated. In both studies, the participants performed various tasks and answered questionnaires on their perception of the indoor climate. As shown here, higher room temperature deteriorates human perception of the indoor climate in classrooms, and the use of intermittent air jet cooling improves the perception of indoor climate just like cooling by reducing the room air temperature. This study contributes to further knowledge of how convective cooling can be used as a method of cooling in school environments so as to improve on building energy use.

Abstract [en]

Individuals with schizophrenia typically show increased levels of distractibility. This has been attributed to impaired working memory capacity (WMC), since lower WMC is typically associated with higher distractibility and schizophrenia is typically associated with impoverished WMC. Here, participants performed verbal and spatial serial recall tasks that were accompanied by to-be-ignored speech tokens. For the few trials wherein one speech token was replaced with a different token, impairment was produced to task scores (a deviation effect). Participants subsequently completed a schizotypy questionnaire and a WMC measure. Higher schizotypy scores were associated with lower WMC (as measured with operation span [OSPAN]), but WMC and schizotypy scores explained unique variance in relation to the mean magnitude of the deviation effect. These results suggest that schizotypy is associated with heightened domain-general distractibility, but that this is independent of its relationship with WMC.

Abstract [sv]

Det är lätt att undvika att distraheras av det vi ser. Det räcker med att blunda. När det gäller ljud kan vi å andra sidan inte bara stänga av öronen för att slippa höra det. När vi sitter och jobbar, och inte vill höra ljud som finns i bakgrunden, registrerar hjärnan ljudet automatiskt.

Bakgrundsljud, som kan komma från folk som pratar, telefoner som ringer och så vidare, fångar vår uppmärksamhet och gör att vi tappar fokus på den uppgift vi har framför oss. Detta kan i förlängningen leda till irritation och till försämrad prestation och hälsa.

Att vara lättdistraherad har konsekvenser både för ens sociala beteende och för hur man fungerar på en arbetsplats eller skola. En lättdistraherad person som har sin arbetsplats i ett öppet kontorslandskap till exempel, där bakgrundsljud är mycket vanligt, presterar sämre än hen skulle göra på ett privat kontor där man generellt sett blir mindre störd. Vissa störs emellertid mer än andra. Varför är det så? En del av svaret på frågan är att människor varierar i något som kallas arbetsminneskapacitet. Arbetsminne är en minnesfunktion som används för att tillfälligt lagra och bearbeta information som vi har i medvetandet. Storleken på arbetsminnet (arbetsminneskapaciteten) kan variera mellan människor, och prestationen på många uppgifter, till exempel att läsa och skriva, beror på arbetsminneskapaciteten. Forskning har också visat att individer med låg arbetsminneskapacitet är mer lättdistraherade jämfört med individer med hög arbetsminneskapacitet.

Distraktion, schizotypy och arbetsminne Att vara mer lättdistraherad än andra är något som människor med hög grad av schizotypy känner igen sig i. Detta gäller både för dem som har diagnosen schizofreni och för dem som inte har diagnosen men som ändå har symtomen. Människor med hög grad av schizotypy har svårare än andra att hålla kvar uppmärksamheten och förbli fokuserade på en uppgift i en bullrig miljö. Ofta har de även sämre arbetsminne än andra, vilket innebär prestationsförluster i många situationer. En hypotes har därför varit att sambandet mellan schizotypy och distraktion beror på det sämre arbetsminnet.

I en nyligen publicerad studie1 testades denna hypotes, men det visade sig att variationer i arbetsminne inte kan förklara sambandet mellan schizotypy och distraktion. Individer som klassificerades ha ”hög grad av schizotypy” var mer distraherade av oväntade ljud under såväl en visuospatial som en verbal uppgift, jämfört med dem som klassificerades ha ”låg grad av schizotypy”. Samma mönster hittades för dem som klassificerades ha låg kontra hög arbetsminneskapacitet.

Det intressantaste resultatet från studien var emellertid att schizotypy och arbetsminneskapacitet bidrog på olika sätt till hur lätt individerna distraherades av det överraskande ljudet. Detta innebär att olika mekanismer ligger bakom den uppmärksamhetsproblematik som är kopplad till schizotypy jämfört med den problematik som är kopplad till sämre arbetsminneskapacitet. Med andra ord verkar det som om variationer i arbetsminne inte kan förklara varför individer med hög schizotypy har uppmärksamhetsproblem.

Exakt hur arbetsminneskapacitet och schizotypy skiljer sig åt är något som författarna till studien endast kunde spekulera om. En hypotes som är välgrundad i litteraturen är emellertid att variationer i arbetsminneskapacitet bidrar till distraherbarhet genom att påverka hur väl människor lyckas avgränsa uppmärksamhetens omfång till den uppgift de håller på med. Hög schizotypy bidrar å andra sidan genom att göra det svårare att ignorera saker i omgivningen, vilket skulle kunna bero på brister i habituering. Det innebär i det här fallet att hög schizotypy leder till svårigheter att vänja sig vid störningsfaktorn över tid, i takt med att man får allt mer erfarenhet av bakgrundsljudet.

Slutsats

Vi drar slutsatsen att arbetsminne och schizotypy tenderar att samvariera på ett sådant sätt att människor med hög grad av schizotypy också tenderar att ha låg arbetsminneskapacitet. Men det är inte den låga arbetsminneskapaciteten i sig som skapar uppmärksamhetsproblemen hos dessa individer. En viktig implikation av denna slutsats är att ”arbetsminnesträning” (det vill säga interventioner i form av träningsprogram som syftar till att öka arbetsminneskapaciteten) inte bör bidra till att minska uppmärksamhetsproblematiken för människor med hög grad av schizotypy.

Abstract [en]

Studies have found a preference bias for “environmentally friendly” or “green” artifacts and buildings. For example, indoor environments are more favorably viewed when the building is labeled/certified “green”, in comparison with one that is not labeled/certified, even though the two environments are actually identical. The present study explored how physical properties of the indoor environment (high vs. low temperature) and labeling (“green” vs. “conventional”) interacts in their effect on environment perception. Participants performed a series of tasks in four indoor environments with different labels (low vs. high carbon footprint) and different temperatures (23°C vs. 28°C). Label and temperature were manipulated orthogonally. The participants’ environmental concern was also measured. The environmentally concerned participant assigned higher thermal acceptance and satisfaction scores to the environment labeled “low carbon footprint” (i.e., “green” certified) compared to the environment labeled “high carbon footprint” (i.e., not “green” certified), but only in the cooler thermal environment. Environmentally indifferent participants’ perception of the environment did not differ depending on label or room temperature. The results suggest that a “green” label positively influence the perception of the indoor environment for occupants, but only when the temperature is within the acceptable range as proposed in guidelines for “green” buildings.

Abstract [en]

The study reported herein builds on occupant response to an intermittent air jet strategy (IAJS), which creates periodic airflow and non-isothermal conditions in the occupied zone.  Previous research has highlighted the benefits of IAJS on thermal climate and supports energy saving potential in view of human thermal perception of the indoor environment. In this study, the goal was to explore occupant acceptability of air movements and perceived indoor air quality, and to determine a way of assessing acceptable air movement conditions under IAJS. Thirty-six participants were exposed to twelve conditions: three room air temperatures (nominal: 22.5, 25.5 and 28.5 oC), each with varied air speeds (nominal: <0.15 m/s under mixing ventilation (MV), and 0.4, 0.6 and 0.8 m/s under IAJS) measured at the breathing height (1.1 m). The results show that participants preferred low air movements at lower temperatures and high air movements at higher temperatures. A model to predict percentage satisfied with intermittent air movements was developed, and predicts that about 87% of the occupants within a thermal sensation range of slightly cool (-0.5) to slightly warm (+0.5), in compliance with ASHRAE standard 55, will find intermittent air movements acceptable between 23.7 oC and 29.1 oC within a velocity range of 0.4 – 0.8 m/s.  IAJS also improved participants’ perception of air quality in conditions deemed poor under MV. The findings support the potential of IAJS as a primary ventilation system in high occupant spaces such as classrooms.

Abstract [en]

It is widely held that single-word lexical access is a competitive process, a view based largely on the observation that naming a picture is slowed in the presence of a distractor-word. However, problematic for this view is that a low-frequency distractor-word slows the naming of a picture more than does a high-frequency word. This supports an alternative, response-exclusion, account in which a distractor-word interferes because it must be excluded from an articulatory output buffer before the right word can be articulated (the picture name): A high, compared to low, frequency word accesses the buffer more quickly and, as such, can also be excluded more quickly. Here we studied the respective roles of competition and response-exclusion for the first time in the context of semantic verbal fluency, a setting requiring the accessing of, and production of, multiple words from long-term memory in response to a single semantic cue. We show that disruption to semantic fluency by a sequence of to-be-ignored spoken distractors is also greater when those distractors are low in frequency, thereby extending the explanatory compass of the response-exclusion account to a multiple-word production setting and casting further doubt on the lexical-selection-by-competition view. The results can be understood as reflecting the contribution of speech output processes to semantic fluency.
