After some preliminary research among facilitators that examined the objectives of groups who meet at LEF, the relevant psychological processes were organised into three main categories: 1) openness and cooperativity, 2) creativity, and 3) focus, concentration and productivity. These processes were studied in four different (experimental) spaces. Two of the spaces were those used most by the facilitators (the living room and work area), and two others were added based on the literature study (one predominantly blue and one predominantly red space). Performance by test subjects in these spaces was compared with performance in a normal office space that served as a control environment. The results show that working at LEF produces results. Openness and creativity are enhanced, an effect that was observed in all of the experimental spaces in the study. Specific spaces (the work area and the blue room) foster the creation of greater levels of mutual trust. A more abstract mindset can be created by having people work in a blue space or the living room – the effects of the blue room on creativity are particularly spectacular. Lastly, it has proven possible to enhance people’s concentration and productivity by having them work in the work area or the red room.

The building is made up of a number of unique spaces and facilities offering advanced features, where it is possible to use wall and other projections, colour, images, sound, layout and catering to create detailed atmospheres that support the processes in which people are involved. The fact that we are influenced by the spaces that surround us is nothing new. But explaining how the physical environment affects our behaviour is a complex problem, and one whose solution requires a multidisciplinary approach. Various academic disciplines have conducted research into this phenomenon. In addition to the obvious disciplines such as architecture and ergonomics, research has also been carried out in the healthcare sector (e.g. hospitals and psychiatric clinics), consumer psychology (e.g. shopping environments), occupational and organisational psychology, and business administration (e.g. companies and organisations). Occupational and organisational psychology sees the physical environment as a variable that can facilitate the use of human resources. After all, employees cost money, and the physical environment affects the extent to which they are able and willing to do their job. According to psychologist Roger Barker, the environment puts us in a position to execute certain behavioural patterns, encouraging certain activities and discouraging us from others. LEF supports this philosophy. Groups come together under the guidance of facilitators at LEF to learn, make progress, and sometimes solve concrete problems. To this end, five different environments have been created (each of which also offers three more specific variants) to promote the necessary LEF: the Recipe for Success Page 7 of 36 Preliminary Research We began this project with a short study among the faci- ‘approach signal’ – people become calm, take on an open litators. We asked them which spaces they used the most, attitude and are more creative. Red emits an ‘avoidance and to what psychological or other end. A large majority of signal’ – people become concentrated, analytical and the facilitators responded, and their goals (and therefore productive. also the participating groups) were classified into three broader categories, which provided the basic structure for our further research: 1) Openness and cooperativity. Openness is a precondition for many processes. Some groups come to LEF with the aim of solving a concrete problem. Sometimes the creation or ‘repair’ of mutual trust is also important. 2) Creativity. This requires little explanation. A creative, outside-the-box attitude is very important for many groups that work at LEF. 3) Focus, concentration and productivity. At LEF this is not an end in itself, but an important stage in a wide range of different processes. The implementation of a creative solution often also requires a stage in which concentration and focused thought are important. These three basic elements also appear in the measurements in the experiment, both in the basic mindset measurements (self-disclosure measures 1; the Navon task measures 2 and 3) as well as the more concrete behavioural measurements. Determining which spaces to study also demanded important consideration. Of course a control environment is needed, for which we selected a normal, rather boring office space. Our choice of experimental spaces emerged from a compromise: we chose the two spaces that were used most often by the facilitators, as well as two spaces that we expected would deliver good results based on the literature study. The two most-used spaces were the ‘living room with fireplace’ and the ‘creative work area’. Based on our literature study (for more details, see the Appendix), we also selected a blue room and a red room. Colours often exert a very direct influence on psychological processes. Blue emits an Page 8 of 36 Method Navon task.

For example, the word ‘boat’ can be related to the three LEF: the Recipe for Success Page 9 of 40 words ‘tug’, ‘gravy’ and ‘show’.

As the name suggests, this task relates to how effectively people can negotiate. Participants were assigned one of two roles (purchaser or salesperson). Couples were then assigned who did not know each other, in order to negotiate the sale or purchase of 50 refrigerators [cf. 4]. There were four aspects to be discussed: price, warranty, delivery deadlines and payment deadlines. Five options were available under each aspect. Each negotiator received an outline containing information on his/her returns, but without any information on the other negotiator. The task is integrative, in the sense that the aspect most important to the purchaser (i.e. the payment terms) meant little to the salesperson, and the aspect least important to the purchaser (i.e. the price) was the most important to the salesperson. If pairs make large concessions on the less important aspects, the mutual gain is greater than opting for the less ideal 50-50 split. When participants carried out this task for the second time, they had to negotiate terms and conditions of employment: salary, salary increases, holidays and health insurance. Participants also changed roles: purchasers became the union (= salesperson) and salespeople became the management (= purchaser). They were given ten minutes to reach an agreement. They were also told that they could win €10 if they managed to beat their partner at the negotiation. Trust game. As the name suggests, this game was about measuring trust. The participants were told that they were to perform a task with somebody in another room, for which the computer would make a wireless connection to another computer. Participants were told that from the €10 they had perhaps won, they could elect to give part of it (amount ‘x’) to the other participant. This amount would then be tripled and sent to the partner, who would then receive information on how much the participant had given them, and would be able to split the amount. In reality, this partner did not exist. Page 10 of 36 Results Navon task. This task also demonstrated positive effects.

This is also a reason why we can assume that the actual effects at LEF are even greater than those observed in the study.A number of recommendations can be made based on the study (besides the usual ‘Keep up the good work!’): Although the atmosphere in the various LEF spaces clearly has an effect, these effects are clearly less direct than those of co- LEF: the Recipe for Success Page 13 of 36 Appendix: Literature Study and Wolfgang Schnelle developed the Bürolandschaft, or Bitner (1992) [1] – ‘… there is a surprising lack of ‘open office’: a design approach that replaced fixed walls and empirical research or theoretically based frameworks structures with movable screens, flower boxes and adjustable addressing the role of physical surroundings in (con- furniture to improve the flow of communication.

The purpose of this study is to examine how a range of physical environmental stimuli affect psychological processes, and therefore our behaviour. With reference to LEF future center, we are particularly interested in the effects on specific psychological processes, such as thinking creatively. Although the amount of research in this area is still quite small, the research that has been conducted does enable us to formulate some theories and possibly explain the observed effects.

Scaffolding is important during the Figure 6) [5]. incubation phase, when the creative process takes place within the context of space, instruments, people and information. Or in other words: when cognitive processes are influenced by the environment in which they occur. Once we enter the insight phase, imagination becomes important – the representation in our mind of something that does not yet exist. This is the mediating process between existing knowledge, and knowledge that has been integrated into new knowledge. In the final phase, ideas are materialised. It is a known fact that we are able to remember things better if we try to remember them in the same room where we learned them. It is therefore imperative to write down or sketch budding ideas straight away, before leaving the space and forgetting the idea.

When we go to a shop and wish to make a lovey-dovey in a restaurant, they are often sitting in exactly purchase, we believe that we consider things properly the same position. We subconsciously imitate what we see – before making a decision. Often, however, we do but why? Seeing somebody with their legs crossed activates not [9]. In his book, American psychologist Robert the same representation of the behaviour in our minds as Cialdini talks about ‘click-zoom’ responses [10], or if we had crossed our own legs. By doing what others do, the fact that certain environmental stimuli have a we understand what they do. Even just the activation of a direct impact on our behaviour. For example: we see representation like this is enough to stimulate our muscles a shop sign that says ‘while stocks last’, which tells us into adopting the same behaviour. As the example shows, that now is the only time we can make the purchase this behaviour can be activated through perception, but also (click), whereupon we place the product in our trolley by thought, e.g. if you think about sitting properly.

The more frequently people restaurant more often wiped away the crumbs that inevitably have been exposed to the work area/creative preset and fall when eating this crumbly, toast-like biscuit. have had creative ideas there, the stronger the association becomes between the preset and creative thought. This allows us to make three relevant observations. The subconscious and other effects of the surroundings on our behaviour are stronger if exposure to the environment is goal-oriented. We are more receptive to the influence of the environment if we use it as it is intended. People studying in the library are quieter than people who just need to walk through it to get to the other side of the building. In the living room/fireplace preset, you will be more open if that is your goal; more so than if you just need to give somebody a status update. The questionnaire answered by the facilitators showed that the four most-used presets are used roughly for four different purposes. Aside from the fact that the facilitators’ descriptions all correspond to each other, they also correspond to the purpose of the preset as described in the moodbook. Regarding this initial observation, it is important to note that the facilitators are aware of the purpose for which a preset ought to be used, and that everybody agrees on this point. Secondly, people allow their behaviour to be influenced Page 22 of 36 Mood and Behaviour single-cell organisms through to animals and people.

They also produce more uncommon associations and take more risks in negotiations; in other words, they stick less strictly to rules and strategies. People in a good mood think at a more abstract level (i.e. animals, elections, opinions) whereas people in a less happy mood think at a more specific level (i.e. my sister’s hamster, the Obama election, being in favour of euthanasia).

This type LEF: the Recipe for Success Page 31 of 36 The evolutionary approach says that the best thing to do is associations or to remember things. A teddy bear is made using to integrate elements of nature into spaces, such as plants or soft materials to make it seem huggable, and a car with leather imitations of nature (e.g. flower ornaments, nature posters). upholstery to emanate luxury. Another way is to imitate the mathematical relationships that occur in nature. A fractal is a geometric figure that is self-similar, Gestalt psychologists believe that we perceive a product as a i.e. it is made out of parts that are more or less the same as the whole. A car is therefore perceived as a car, and not as a col- figure itself. The most well-known example is that of a fern. lection of parts such as tyres, headlights and a steering wheel. Waves, flames and clouds can all be duplicated using fractals. If the shape requires more in-depth processing, then we also A fractal pattern on the wall or floor stimulates creativity and look at the individual parts.

A wall with warm, dark colours seems to SUV.

However, this can also cause people to lose their privacy and comfort, which we sometimes need during a creative process. A grain of salt The above analysis clearly shows that atmospherics influence consumer behaviour. But what happens, for example, if we very much like a piece of music (i.e. positive mood) but it is too loud (i.e. too much stimulus)? We need to expand our knowledge not only at the micro but also at the macro level. For what will happen if we listen to loud music (i.e. lots of stimulus) in a room with dimmed lighting (i.e. little stimulus) or warm lighting (i.e. positive mood)? Until now research has isolated the effects of environmental stimuli, meaning that we do not know which elements influence us the most. Secondly, little research has been done into segmentation. For example, we know that women are quicker to admit to being sensitive to noise, and that intellectuals are in principle less sensitive. But when we walk along a shopping street we see clear differences between shops for men, women and young people. It would therefore seem that managers still continually alter their shopping environments in order to influence their customers, without knowing exactly what effect the changes will have.
