Abstract
As part of the built environment objects and interior design features can affect thoughts, emotions and behaviour in various ways. Referring to the concept of material and conceptual priming (Kay et al., 2004; Berger & Fitzsimons, 2008), these objects can provoke associations and by that subconsciously activate mental concepts which influence emotional states, judgements and subsequent behaviours. In many healthcare facilities, the formal-aesthetic design of the built environment visually conveys the concept of institutionalisation through clinical and sterile styles, impersonal and standardised configurations and a lack of individualisation. This applies in particular to the setting of psychiatric facilities in which from a clinical point of view sterile and impersonal aesthetics are not required and might even be detrimental to the therapeutic processes. However, there is reason to believe that the use of everyday objects can support therapeutic processes and thus be seen as an element of psychosocially supportive design (Ulrich, 1997) in two ways. Firstly, everyday objects derived from domestic contexts refer to aesthetics that are contrary to the concept of institutionalisation. Instead by communicating features of comfort and subtle luxury they might activate the mental concept of valorisation which can be seen as an important resource in therapeutic settings that strengthens commitment and trusts. Secondly, offering choice of a variety of everyday objects in psychiatric settings enables patients to exert control in a context that otherwise is characterised by total loss of control. This increased sense of control is an important part of Antonovsky's sense of coherence (1979) and a valuable asset for recovery and empowerment of psychiatric patients.
