Part of the stimuli used were described in the original study by Ameel et al. (2009, 2005). The original set consisted of 73 pictures of storage containers, referred there to as “the bottles set”; we refer to them here as “containers” for greater accuracy. We expanded the existing set with 119 new stimuli, the full set totaling 192 pictures. This set aims to represent the full range of objects that exist within the domain of household containers. We introduced a larger variety by adding objects of different materials, shapes, and functionalities, and larger and smaller objects. The new pictures were made according to the same guidelines used by Ameel et al. (2005, 2009). The objects were photographed in color against a neutral background with a constant camera distance to preserve relative size. A ruler was included in front of each object to provide additional size information. For objects that were small and hard to inspect on the picture, enlargements in the left upper corner were added, to ensure that the object would be clearly visible despite the small size. Like in the original study, the stimulus set contains objects that can be found at work or at home. The objects present in the set were likely to receive the names bottle, jar, container, or box in English. In Dutch, we anticipated that the most frequently given names would likely be fles, pot, doos, and bus. In French the most likely names would be bouteille or flacon, pot and boîte. Some examples of the expanded stimulus set can be found in Figure 2.
