Seeking Proxies for Internal States as a Possible Alternative for Rationality and Experientiality
The Cognitive-Experiential Self-Theory (CEST) proposes rationality and experientiality as independent personality constructs explaining how people process information. Recent empirical studies show that some people have low scores on both of these dimensions (the so-called disengaged profile). Another model, Seeking Proxies for Internal States (SPIS), primarily proposed to explain obsessive-compulsive tendencies, provides a framework under which both rationality and experientiality can be understood as internal resources of a person. Low rationality and experientiality could thus be overcome by seeking external clues. In two subsequent studies on independent nonclinical samples (psychology students N = 268 and technical sciences students N = 549), we examined the relationship between constructs from CEST and SPIS models, and in addition, explored their patterns of interoceptive awareness (IA) in Study 2. A latent profile analysis showed that the disengaged profile was related to high SPIS and OC tendencies in both samples. In addition, rationality and experientiality had similar and more positive correlations with some IA dimensions, compared to SPIS (and OCI)-IA correlations. Thus, impaired connection to internal states together with OC tendencies might contribute to the understanding of the specific thinking style of those who do not primarily rely on either rationality or experientiality
Does cultural participation make us happier? Favorite leisure activities and happiness in a representative sample of the Serbian population
Istraživanja o doprinosu aktivnosti u slobodno vreme, a posebno o doprinosu kulturne participacije liÄnom blagostanju i doživljaju sreÄe predstavljaju relativno novu liniju istraživanja. Iako ima dosta nalaza o pozitivnoj vezi izmeÄu liÄnog blagostanja i kulturne participacije, rezultati nisu u potpunosti konzistentni, Å”to se bar delimiÄno može objasniti razliÄitim teorijskim shvatanjima ovih složenih pojmova (kulturna participacija, liÄno blagostanje i sreÄa), kao i njihovim razliÄitim operacionalizacijama, primenjenim istraživaÄkim tehnikama i uzorcima. Ovo istraživanje sprovedeno je na reprezentativnom uzorku graÄana Srbije starijih od 15 godina (N=1521, 46% muÅ”karaca, proseÄan uzrast 41.5). Terensko prikupljanje podataka realizovano je u oktobru i novembru 2019. godine. Kao potencijalni prediktori subjektivnog doživljaja sreÄe ukljuÄeni su: 1. socio-demografske varijable (pol, starost, stepen obrazovanja, radni status, finansijski status), 2. subjektivna procena zdravstvenog stanja, i 3. lista aktivnosti saÄinjena na osnovu prethodnih istraživanja u domenu slobodnog vremena i kulturne participacije (koja je odreÄena tako da obuhvata kulturnu produkciju, privatnu i javnu kulturnu potroÅ”nju, a ispitanici su ocenjivali u kojoj meri im je omiljena svaka od navedenih aktivnosti). Analizom glavnih komponenti izdvojeno je Å”est latentnih dimenzija aktivnosti u slobodno vreme: 1) kulturna participacija u užem smislu, 2) filmovi i zabava, 3) narodnjaci i porodica, 4) aktivnosti na otvorenom, 5) sport i 6) e-knjige i e-novine. Na nivou celog uzorka subjektivni doživljaj sreÄe je bio visok, proseÄna ocena 5.03, na 7-stepenoj Likertovoj skali. Rezultati linearne regresije izdvojili su najbolje prediktore subjektivnog doživljaja sreÄe. SreÄniji su ljudi koji pozitivnije ocenjuju svoje zdravstveno stanje, imaju viÅ”i finansijski status, ali i oni koji su viÅ”e obrazovani. Pozitivnijem doživljaju sreÄe takoÄe pozitivno doprinose tri obrasca omiljenih aktivnosti u slobodno vreme: narodnjaci i porodica, aktivnosti na otvorenom i kulturna participacija. Rezultati su diskutovani u svetlu kompleksnosti ispitivanih fenomena, a posebno su istaknute moguÄnosti za naredna istraživanja, kao i praktiÄne implikacije za donosioce odluka o u oblasti kulturne politike.Research on the contribution of leisure activities in general and specifically cultural participation to personal wellbeing represents a relatively new and promising line of research. Results, however, are mixed - partly due to various definitions and measures of key variables, as well as their complexity and many confounding variables. This research was conducted on a sample representative for the general population of Serbia (N=1521). As potential predictors of wellbeing, we investigated a number of socio-demographic variables (gender, age, education level, employment status, financial status), subjective health status, and a list of leisure activities selected based on past research from leisure and cultural participation paradigms. A principal component analysis revealed six latent dimensions of leisure activities that were labeled as: 1) cultural participation (in a strict sense), 2) movies & entertainment, 3) folk & family, 4) outdoor activities, 5) sport, 6) e-books & e-news. A stepwise linear regression showed that subjective happiness was best predicted by a higher subjective health status, higher financial status, and higher education level, while from the domain of leisure activities, significant positive predictors were 'folk & family', 'outdoor activities', and 'cultural participation' components. Results are discussed in light of the complexity of examined phenomena, as well as practical implications for policy decision making
Why festival museum attendance cannot predict regular museum attendance: Examining the attitude-behavior relationship
Velika poseÄenost muzeja tokom 'NoÄi muzeja' nasuprot malom interesovanju za programe ovih ustanova ostalim danima, poslužila je kao povod za ispitivanje moguÄnosti i prepreka da festivalska publika postane redovna muzejska publika i pored specifiÄnosti festivala u poreÄenju sa redovnim funkcionisanjem muzeja. Zastupljenost onih koji muzeje poseÄuju samo tokom te jedne noÄi u godini kao i onih koji ih poseÄuju i ostalim danima pružila je priliku za komparativno ispitivanje njihovih stavova o poseÄivanju muzeja, subjektivnih normi, opaženih prepreka i namera da ÄeÅ”Äe poseÄuju muzeje u buduÄnosti (N=1480). Rezultati pokazuju da se muzeji pretežno opažaju kao druÅ”tveno korisni edukativni centri, Äije se glavne slabosti ogledaju u imidžu statiÄnih i dosadnih ustanova. Ipak, u festivalskoj noÄi, znaÄajan procenat posetilaca muzeja iskazuje nameru da muzeje poseÄuje ÄeÅ”Äe u buduÄnosti. ZaÅ”to se te namere ne realizuju i kakve su moguÄnosti da se to promeni diskutovano je u okviru teorije planiranog ponaÅ”anja i s obzirom na ranija istraživanja o kulturnoj potroÅ”nji.This study addresses the fact that during the one night festival 'Museum Night', tens of thousands of visitors find themselves in museums, which stands in sharp contrast to the lack of museum visitors during the rest of the year. Taking into account conceptual differences between festivals and regular museum programs, we examined the obstacles that prevent festival visitors from become regular museum visitors. Using the two stage stratified sample (N=1480) of visitors of the 'Museum Night' in Serbia 2012, we identified 39% of those who have never visited a museum during previous twelve months. This allowed for comparison between this group of visitors and the regular museum visitors based on their socio-demographic characteristics and their cultural habits. In addition, we assessed their attitudes towards museums, subjective norms about visiting museums, and perceived barriers for more frequent visits (perceived controlability). The choice of constructs was guided by Ajzen and Fishbein's Theory of planned behavior (1985; 2011). We analyzed if they could predict (a) intentions to visit museums in the future and (b) visits to the museums in the previous year. The attitude towards museums was proven to be a good predictor of both intentions and past behavior, whilst subjective norms and perceived control were better indicators of past behavior. Results demonstrated that museums were perceived as predominantly educational institutions, with their main image-related drawbacks being lack of dynamics and excitement. In spite of that fact, a significant number of festival visitors did express their intentions to visit museums more often in the future. We discussed how these intentions could be addressed in public communication in order to translate them into behavior. We also suggested how both descriptive and prescriptive norms could be employed to widen potential museum audience and which strategies could improve the image of museums as more proactive and appealing
Prvi podaci o parazitskim grinjama roda Riccardoella Berlese (Acari: Ereynetidae) na puževima pluÄaÅ”ima u Srbiji
The paper presents the first data on slug mites Riccardoella (Riccardoella) limacum (Schrank) and R. (Proriccardoella) oudemansiThor (Acari: Ereynetidae) in Serbia. The two parasitic species were detected on seven species of snails and slugs (Gastropoda, Pulmonata) in Serbia. Riccardoella limacum, which is a specialized snail parasite, was found in Helixpomatia L. and H. lucorum L species of the family Helicidae. Riccardoella oudemansi was found exclusively on slug species: Arion lusitanicus Mabille (Arionidae), Tandonia budapestensis (Hazay) (Milacidae), Limacus flavus (L.), Limax maximus L. and L. cinereoniger Wolf (Limacidae).U radu su izloženi prvi podaci o nalazima pluÄnih grinja Riccardoella (Riccardoella) limacum (Schrank) i R. (Proriccardoella) oudemansiThor (Acari: Ereynetidae), koje su zabeležene u Srbiji na sedam vrsta puževa i golaÄa (Gastropoda, Pulmonata). Riccardoella (R.) limacum, koja je parazit puževa sa ljuÅ”turom, naÄena je na vrstama familije Helicidae, Helixpomatia L. i H. lucorum L. Nasuprot tome, vrsta R. (P.) oudemansi nalažena je iskljuÄivo na golaÄima, na vrstama: Arion lusitanicus Mabille (Arionidae), Tandonia budapestensis (Hazay) (Milacidae), Limacus flavus (L.), Limax maximus L. i L. cinereoniger Wolf (Limacidae)
Muzeji Srbije kao deo kulturno turistiÄke ponude za porodice sa decom
Monografska studija āMuzeji Srbije kao deo kulturno turistiÄke ponude za porodice sa decomā je rezultat istraživaÄkog projekta koji je bio fokusiran na jaÄanje saradnje turistiÄkih operatera i muzeja u Srbiji, odnosno ohrabrivanja njihovog zajedniÄkog rada na razvijanju kulturno-turistiÄkog proizvoda namenjenog porodicama (odraslima i deci uzrasta do 15 godina). Predmet istraživanja jesu moguÄnosti za primenu koncepta āporodiÄni dan u muzejuā u funkciji razvoja kulturnog turizma sa akcentom na porodiÄnim odmorima. Naime, āPorodiÄni dan u muzejuā je koncept koji praktikuju brojni muzeji Å”irom sveta, a reÄ je o specijalnim voÄenjima kroz stalnu i/ili povremene izložbe za decu i njihove roditelje uz prateÄe programe kao Å”to su kratke predstave, video projekcije ili radionice na kojima pre svega deca uz pomoÄ kustosa i roditelja na sebi svojstvene naÄine (npr. crtežom, reÄju, pokretom) izražavaju Å”ta su nauÄili tokom posete. Koncept je, pre svega, osmiÅ”ljen i namenjen lokalnom stanovniÅ”tvu, ali može biti veoma atraktivan za turiste/porodice na odmoru jer omoguÄava potpuno drugaÄiji doživljaj u odnosu na rutinske posete lokalnim muzejima u okviru turistiÄkih aranžmana. Takva opcija prepoznata je u gradovima kao Å”to je San Sebastian u Å paniji, Otava u Kanadi, oblasti Meinfeld u Å vajcarskoj, itd.
Rezultati istraživanja poslužiÄe za kreiranje modela programa u kome su porodiÄni dani u muzejima u Srbiji centralna aktivnost. Pored uÄeÅ”Äa u porodiÄnom danu u muzejima, turisti bi se upoznali i sa drugim znamenitostima grada/opÅ”tine (prirodne lepote, objekti arhitektonskog nasleÄa ukljuÄujuÄi i tradicionalno neimarstvo, gastronomija, tradicionalni zanati, itd.). Inicijalno, reÄ je o izletima/dvodnevnim aranžmanima u okolini centara koji privlaÄe veÄi broj turista i gde se može oÄekivati veÄe interesovanje graÄana za porodiÄne aktivnosti van mesta boravka (npr. Beograd, NiÅ”, Novi Sad, Subotica, Jagodina, Kragujevac).
Koncept je osmiÅ”ljen u kontekstu kulturnog turizma, koji poslednjih decenija Å”irom sveta predstavlja granu u usponu i beleži sve znaÄajnije ekonomske efekte (JelinÄiÄ, 2010). Prema prognozama Svetske turistiÄke organizacije (UNWTO) veÄ 2020. godine kulturni turizam Äe postati vodeÄa grana turistiÄke privrede u svetu. Kulturno nasleÄe je jedan od najznaÄajnijih resursa za razvoj kulturnog turizma i osnova njegovog održivog razvoja. Interpretacija nasleÄa je baziÄni sadržaj kulturno turistiÄkog proizvoda (ÄukiÄ i TodoroviÄ, 2008). U tom smislu posebnu ulogu imaju muzeji, kao ustanove kulture koje istražuju, Äuvaju i prezentuju nasleÄe, a nasleÄe je okosnica druÅ”tvenog pamÄenja, te tako i važan faktor u izgradnji kulturnog identiteta.
Iskustva u muzejima, kao deo kulturne participacije, doprinose jaÄanju spona pojedinaca i zajednice, ali i razumevanju razliÄitosti drugih grupa i zajednica. TakoÄe, posete muzejima jesu nezaobilazan deo turistiÄkih putovanja. Ipak, kada je reÄ o domaÄim turistima, lokalnom stanovniÅ”tvu, posete domaÄim muzejima predstavljaju najmanje popularne aktivnosti u slobodno vreme (CvetiÄanin 2007; MrÄa 2011a, 2011b; OpaÄiÄ i SubaÅ”iÄ 2016). Istovremeno muzejske manifestacije (āNoÄ muzejaā, āMuzeji Srbije deset dana od 10 do 10ā) i posebne izložbe (npr. āMankala ā misaona igraā u Muzeju afriÄke umetnosti i āPupin ā od fiziÄke do duhovne realnostiā u Istorijskom muzeju Srbije) privlaÄe veoma veliki broj posetilaca (MartinoviÄ i JokiÄ 2012; JokiÄ i Žeželj 2013; JokiÄ 2016; JokiÄ, MrÄa i MartinoviÄ 2016). Iako je relativno mali broj inovativnih muzejskih programa namenjenih porodicama i deci uzrasta do 15 godina, upravo muzejske manifestacije pokazuju da za takvim vrstama programa postoji interesovanje. Ipak, on je u Srbiji retkost ā praktikuje ga tek nekoliko muzeja, pri Äemu je najÄeÅ”Äe reÄ o povremenim programima bez ustaljene dinamike. U ovoj studiji Äe najpre biti opisani kljuÄni koncepti: kulturni turizam u svetu i kod nas, sa posebnim osvrtom na ulogu muzeja u tom kontekstu. Zatim sledi prikaz istraživaÄkog dela, koji obuhvata tri celine: 1. analizu odabranih gradova u Srbiji, na osnovu sekundarnih izvora i terenskog istraživanja; 2. anketu kustosa u muzejima; 3. anketu roditelja maloletne dece, kao potencijalnih korisnika test tura, dok su na kraju studije predstavljena zakljuÄna razmatranja i preporuke proizaÅ”le iz istraživanja
Emissions in environment and wastewater treatment in some sugar factories in Serbia
In a beet-sugar plant numerous sources of wastewaters exist. The cleanest water is from the evaporators (150% calculated on the sugar-beet), which contains ammonium and ammonium carbonate. The waste water used for cooling afterwords is used for beet washing (830% calculated on the sugar-beet). The third kind of waste water is used for washing beets soked with dirt. This water contains some residues, suspended solids, organic compounds. The fourth group is fecal waste water, which is treated in a system designed for recycling the waste. This system is composed of two decanters. Calcium-carbonate, aluminium sulphate could be used as precipitating agents. Sugar factories that manipulate with 500 tonnes of sugar-beet need lagoons with an area of about 30-40ha. Since 2006 the sugar factory near Novi Sad has not been letting the effluent into the chanal Bezdan-Vrbas. The waste water which is let into the lagoons has about 3000mg/l BOD5, and 4-5 months later the level of BOD5 decresed for about 70%
A novel carbon paste electrode based on nitrogen-doped hydrothermal carbon for electrochemical determination of carbendazim
In this work, a new carbon paste electrode, prepared from nitrogen-doped hydrothermal carbon (CHTCN) was applied for the electrochemical detection and determination of carbendazim fungicide. CHTCN samples with the nominal nitrogen content 0.05-0.5 wt. % in glucose precursor were prepared by simple, low-cost synthesis with the accompanying carbonization to 1273 K. The presence of nitrogen in CHTCN samples was confirmed by elemental analysis. Characterization of CHTCN as material for carbon paste electrode was achieved by cyclic voltammetry measurement of the Fe(CN)(6)(3-/4-) redox couple. The results showed that best electrochemical response was obtained from the sample with a nominal nitrogen concentration of 0.1 wt. % and with tricresyl phosphate as a binder. During the development of a differential pulse stripping voltammetric method for carbendazim determination applying new electrode, the following experimental parameters were studied: the sort and amount of binding liquid, the effect of pH, accumulation potential and accumulation time. Under optimal conditions, the electrode offered linearity in the wide concentration range from 25 to 490 ng cm(-3) and an estimated detection limit of 1.21 ng cm(-3). Moreover, the electrode showed good stability, high selectivity and satisfactory anti-interference ability. Finally, the developed method was successfully applied for the determination of carbendazim traces in spiked tap and river water samples

The effect of temporal and social distance on decision-making
Istraživanja pokazuju da se saveti Äesto razlikuju od odluka za sebe, kao i da se
odluke za sebe razlikuju u zavisnosti od toga koliko je vremenski udaljen njihov ishod.
Prvi fenomen izuÄava se kao efekat socijalne distance, a drugi kao efekat vremenske
distance na odluÄivanje. Neki modeli prepoznaju sliÄnosti u efektima vremenske i
socijalne distance na odluÄivanje, ali za to nude parcijalna objaÅ”njenja: preko
ukljuÄenosti afekata, Äiji se znaÄaj zanemaruje sa poveÄanjem distance ili ukljuÄenosti
druÅ”tvenih vrednosti Äiji se znaÄaj poveÄava sa poveÄanjem distance. Prema teoriji
nivoa konstrukcije (engl. Construal level theory, CLT) u osnovi efekta distance na
odluÄivanje je kognitivni mehanizam nezavisan od ukljuÄenosti afekata, socijalnih
vrednosti i bilo kojh drugih sadržaja u situaciji odluÄivanja: na maloj distanci mentalne
reprezentacije (konstrukcije) su konkretne, bogate perifernim detaljima i odnose se na
izvodljivost cilja (konstrukcije nižeg nivoa); na velikoj distanci reprezentacije su
apstraktne, sa manjim brojem centralnih karakteristika i odnose se na poželjnost cilja
(konstrukcije viŔeg nivoa).
PoÅ”avÅ”i od ovih pretpostavki osmislili smo studiju od Äetiri konceptualno
povezana ogleda u kojima smo ispitivali: a. da li vremenska i socijalna distanca imaju
efekta na odluÄivanje (izbor i dopadljivost opcija); b. da li ima sliÄnosti izmeÄu efekata
vremenske i socijalne distance na odluÄivanje; c. da li se dosledno potvrÄuju
pretpostavke CLT o nivou konstrukcija u osnovi efekata vremenske i socijalne distance
na odluÄivanje bez obzira na sadržaj/tip konstrukcija viÅ”eg nivoa (u kojoj meri su
povezane sa druŔtvenim vrednostima) i sadržaj/tip konstrukcija nižeg nivoa (u kojoj
meri okolnosti za izvoÄenje cilja ukljuÄuju afekte). TakoÄe, uporedili smo uloženi
kognitivni napor (procenu teÅ”koÄe odluÄivanja i vreme potrebno za donoÅ”enje odluke)
na razliÄitim nivoima distance, poÅ”to se prema CLT razlike ne oÄekuju, dok drugi
modeli predviÄaju razlike u razliÄitom smeru (ulaganje viÅ”e/manje napora sa
poveÄanjem distance).
U pripremnoj fazi testiranja stimulus materijala uÄestvovalo je 186, a u glavnoj
studiji 436 studenata Univerziteta u Beogradu, sluÄajno rasporeÄenih u grupe prema
nivoima vremenske (Ogledi od 1 do 4) ili socijalne distance (Ogledi 1 i 4). Ispitanicima
su prezentovane situacije izbora aktivnosti na fakultetu, a variran je tip konstrukcija
nižeg nivoa (afektivne/afektivno neutralne prepreke) i tip konstrukcija viŔeg nivoa
(individualni/druÅ”tveni ciljevi). PonuÄene opcije su bile opisane tako da imaju
suprotstavljene prednosti/slabosti na teÅ”koÄi izvodljivosti i poželjnosti cilja. Da bi se
ispitalo da li je efekat distance na odluÄivanje osetljiv na operacionalizaciju zavisne
varijable, ispitanici su birali izmeÄu dve ponuÄene opcije (Ogledi 1, 2 i 3) i/ili su
ocenjivali koliko im se dopada svaka od njih (Ogledi 1 i 4), odnosno u kojoj meri su
spremni da zamene odabranu opciju (Ogled 2).
Rezultati su pokazali da se efekti vremenske i socijalne distance na odluÄivanje
u velikoj meri razlikuju. Efekat vremenske distance na izbor opcija nije se ispoljio i
pored razliÄitih operacionalizacija izbora, manipulacija distancom i primene razliÄitog
stimulus materijala; spremnost na promenu odabrane opcije ukazuje na to da sa
poveÄanjem vremenske distance opada znaÄaj i poželjnosti i teÅ”koÄe izvodljivosti
ciljeva; efekat na dopadljivost opcija nezavisno od izbora ispoljio se tako Ŕto se
dopadljivost manje poželjnog lakÅ”e izvodljivog cilja smanjivala sa poveÄanjem distance,
dok se dopadljivost druge opcije nije menjala. Za razliku od efekata vremenske
distance, socijalna distanca imala je efekat na izbor opcija: poželjniji, teže izvodljiv cilj
ÄeÅ”Äe je savetovan drugima nego biran za sebe, bez znaÄajne interakcije sa tipom
situacije, ali statistiÄki znaÄajno u dva od Äetiri tipa situacije; odabrane opcije uvek su
bile dopadljivije kao savet nego kao izbor za sebe; efekat socijalne distance na
dopadljivost opcija nezavisno od izbora ispoljio se tako Å”to je na veÄoj distanci bila
veÄa dopadljivost poželjnijeg teže izvodljivog cilja, ali samo kada su konstrukcije nižeg
nivoa bile afektivne. Jedine jasne sliÄnosti efekata vremenske i socijalne distance na
odluÄivanje ispoljile su se na meri relativne dopadljivosti (razlika dopadljivosti
poželjnijeg teže izvodljivog i manje poželjnog lakÅ”e izvodljivog cilja) ā bila je
pozitivnija na velikoj distanci. KonaÄno, nije bilo razlika u uloženom kognitivnom
naporu, operacionalizovanom preko procene teÅ”koÄe odluÄivanja i vremena potrebnog
za donoŔenje odluke, u zavisnosti od vremenske i socijalne distance.
Rezultati su diskutovani s obzirom na pretpostavke CLT i modela koji efekte
distance na odluÄivanje objaÅ”njavaju ulogom afekata ili ulogom socijalnih vrednosti.
Razmotren je i problem operacionalizacije kljuÄnih varijabli i moguÄe implikacije na
zakljuÄivanje o psiholoÅ”kim mehanizmima u osnovi efekta distance na odluÄivanje.Giving advice to others often differs from deciding for oneself. Somewhat
surprisingly, current decisions for oneself differ from future decisions for oneself in the
similar manner. There is extensive evidence for both phenomena, known as the effect of
social and temporal distance on decision-making. Some theoretical models offer partial
explanations for these effects. For example, when affect is involved in the decisionmaking
process, its role will decrease as the distance is larger (e.g. when advising others
or deciding for future self; Loewenstein, 1996); when the desirable choice option
conforms with social values, their role will increase as the distance is larger (Stone,
Choi, Bruine deBrui& Mandel, 2013). In contrast, the Construal Level Theory (CLT;
Trope & Liberman, 2003; 2010) proposes an underlying universal cognitive mechanism
that accounts for the effects of distance on decision-making regardless of involvement
of affect, social values or any other psychological aspects of the decision-making
situation. If the psychological distance is small, mental representations (construals) are
concrete and rich with peripheral details mostly about the feasibility of a goal (low-level
construal, LC); if the psychological distance is large, mental representations are
abstract, containing few central aspects of the decision-making situation and are mostly
about the desirability of a goal (high-level construal, HC).
We designed a study of four conceptually linked experiments to examine: a.
whether temporal distance and social distance have the expected effects on decisionmaking
(choice / liking of chosen option / liking of options independent of choice) so
that the desirability of a goal would increase while its feasibility would decrease as the
distance increased; b. whether there are systematic similarities between temporal
distance and social distance effects on decision-making; c. whether the CLT
propositions about the role of construal level in explaining the effect of distance on
decision-making is replicated consistently regardless of the content/type of HC (if it
involves personal value, e.g. interest in course topic, or social values, e.g. social
importance of an humanitarian project) and regardless of the content/type of LC (if it is
affect-laden, e.g. taste of the food that has to be consumed as a part of the course study,
or it is more affect-neutral, e.g. convenience of the location of the project). Additionally,
we aimed to compare cognitive effort (measured by estimation of the difficulty of
decision-making and time needed for decision-making) on different distance levels. The
CLT would not expect differences, whereas there are models predicting that larger
distance would lead to investment of more cognitive effort and conversely, other models
predicting the opposite i.e. less cognitive effort.
A total of 186 Belgrade University students took part in the preliminary stimulus
testing, and 436 in the main phase. They were randomized to groups with low/high
temporal-distance levels (Experiments 1ā4) or low/high social-distance levels
(Experiments 1 and 4). They were presented with choice situations designed to be
plausible for students. The type of LC (affect-laden or affect-neutral) and the type of
HC (personal or social goals) were within-subject factors. To explore whether the effect
of distance on decision-making is sensitive to the operationalization of dependent
variables, we asked participants to choose between two options (Experiments 1, 2, and
3) and/or estimate how much they liked each of them (Experiments 1 and 4) and/or how
much they were ready to replace the chosen option (Experiment 2).
Results showed that temporal-distance effects and social-distance effects on
decision-making are more different than similar. The increase of temporal distance did
not have an effect on choice despite the variety of: a. operationalization of choice
(categorical/continual variable), b. distance manipulation (imaginative/simulation of
real choice), and c. difference in likeability of the options (more or less emphasized
differences between the types of HC, and more or less emphasized differences between
the types of LC). Readiness to replace the chosen option indicated that both LC and HC
were perceived less important as temporal distance increased. When evaluated
independent of choice, liking options with better LC decreased as the distance was
larger while there was no effect of temporal distance on liking the options with better
HC. In contrast, social distance had the expected effect on choice: the more desirable /
less achievable goal was more often advised to others than chosen for oneself ā the size
of this effect was the largest in situations with affect-laden LC/HC social goal and
affect-neutral LC/HC personal goal; chosen options were always more liked as an
advice rather than as a choice for oneself; effect of social distance on liking options
independent of choice was registered only when LC were affect-laden. The only clear
similarity between temporal and social distance effects on decision making was
registered on a relative liking measure (i.e. difference in liking option with better HC
compared to liking option with better LC): relative liking of options with better HC
increased as the distance was larger. The cognitive effort did not differ with an increase
in temporal nor increase in social distance.
The results are discussed related to predictions of the CLT and other competing
models predicting the effects of specific attributes (affect or social values). We also
addressed the differences that emerged as consequences of different types of
operationalization of dependent variables, which are usually overlooked in experimental
designs.
In concluding, we discussed potential practical implications of the results in
public communication, health, advertising, etc. We explored limitations of this study
and suggested directions for future research
