Refurbishment is an effective circular strategy to lengthen a product’s lifetime. However, refurbished products that are intimately used, such as personal care products, cause a feeling of unease in consumers because they are perceived to be contaminated. In 15 in-depth online interviews with female users of intense pulsed light (IPL) device living...
Article
Refurbishment is an effective strategy to extend product lifetimes in a circular economy. However, consumers believe that refurbished products are contaminated with traces of prior use, which can be indicated by the appearance (e.g., scratches) or functionality (e.g., lower battery capacity) of refurbished products. This research explores strategie...

Full-text available
Many products are disposed of before they have reached the end of their functional life. New technological developments and trends in fashion seem to accelerate consumers’ replacement of products. From an environmental perspective, such early replacement is undesirable. In this paper, we emphasize that product replacement is not only based on ratio...
Article
Full-text available
The prior use and age make refurbished products a less desirable option because they are perceived to be of lower quality, to have a reduced performance and a less attractive appearance. This research investigates one strategy on how to enhance the appearance of refurbished products and thereby encourage circular consumption via refurbishment. In 2...
Article
This research examines proximity as a new interesting strategy to include in the design of more sustainable products. Drawing from the construal level theory, we posit that the environmental sustainability of a product embedding a form of proximity to an environmental solution in its design will be perceived as more concrete and will trigger higher...
Article
Really new products (RNPs) are often difficult to comprehend, which may hinder consumers’ adoption. It is generally believed that designers can stimulate consumers’ comprehension by embodying RNPs in the form of product metaphors. However, empirical evidence for this is lacking. This study empirically examines the effects of product metaphors on co...

Transparency is used in product design across various product categories. Because of the physical property of letting light go through, transparency can create unique visual styles. Transparency can also communicate additional information as a result of what is situated underneath the product cover, which prompts different consumers’ interpretation...
Article
Pay-per-use business models where consumers pay for the unit of service (e.g. a wash) without gaining product ownership are often linked to increased environmental performance. Consumers would become more conscious about consumption patterns and companies would take responsibility for product life cycle issues. Such benefits can only be achieved wh...
Article
Refurbishment presents opportunities for designers to improve the sustainability of new and old products via an experiment and post hoc interviews, this research investigates and explores how information about prior use – offered in a visual (signs of wear and tear) or verbal (textual description) form – influences consumers’ evaluations of refurbi...
Article
Product care is defined as all activities initiated by the consumer that lead to the extension of a product's lifetime.

Keeping a product offering in the system through continued use and between multiple users creates the potential for interactions which become contaminated. These contaminated interactions can cause a barrier to material circulation and extended product lifetimes. This study seeks to identify the underlying design strategies useful in addressing con...
Conference Paper
Full-text available
The purpose of this paper is to present contaminated interaction as a design construct. Interactions with an object can be altered, positively, neutrally or negatively, due to some prior use. In such cases, the interaction departs from the designed condition and is said to be contaminated. This is particularly significant as objects, physical or no...
Article
Consumers often purchase consumer durables without using these products beforehand. Product appearance is then one of the factors that consumers use to form inferences about the experience and credence attributes of consumer durables. For companies, it is important to successfully manage these inference processes of consumers to create a competitiv...

In two experimental studies using washing machines and digital cameras as stimuli, we systematically manipulated the level of novelty (low vs. high) in th...
Article
Theories differ on how typicality and arousal influence aesthetic appraisal and whether these processes together interact or have independent effects on aesthetic appraisal. This research investigates the simultaneous effects of typicality and arousal on aesthetic appraisal for product designs by manipulating both processes separately: typicality b...
Article
Although recent research has explored consumers’ reactions towards mass customization (MC) in general, these studies have considered aesthetic and functional MC as one and the same. In the present article, we focus specifically on consumer response to aesthetic MC because there are some unique factors that influence this type of MC. Providing insig...
Article
People use the appearance of products as a cue for evaluating functional attributes at purchase. This research provides an understanding of this form-function interdependency by investigating the effect of a business-like personality in product appearance on the perceived performance quality of the product. A business-like personality is associated...
Article
Earlier findings have suggested that esthetic appraisal of product appearances is influenced by perceived typicality. However, prior empirical research on typicality and esthetic appraisal of product appearances has not explicitly taken context effects into account. In this paper, we investigate how a specific context influences perceived typicalit...
Article
Understanding how consumers perceive products based on their appearance is of great importance to designers. In this article, we explore the level of novelty of a product appearance as a general design guideline to evoke positive associations about the product's performance quality. Novelty implies the deviation in a product appearance from the cur...
