man personality to remain reliable across cultures (Paunonen et al., 1992). In conclusion:<br />

it might be possible that due to different interpretations of personality<br />

traits, different brand personalities might be perceived. It might therefore be advisable<br />

to work with different subsets of personality traits in order to safeguard and<br />

control a consistent brand personality across cultures (Mooij, 2011).<br />

Another limitation concerns the difference in overarching categorization of<br />

personality traits due to working with both personality traits of characters and traits<br />

of brands. This might mpact on meaning transfer: as there is a gap between traits<br />

which are considered descriptive for human personality (Cattell, Eber and Tatsuoka,<br />

1970; Costa and McCrea, 1992; Goldberg, 1992) and the ones which are descriptive<br />

for brand personality (Aaker, 1997), using one model over another results in either<br />

lack of descriptive quality at the source of the meaning transfer (the character) or<br />

at the target (the brand).<br />

Furthermore, the study primarily focused on the transfer between personality<br />

traits from the character onto the brand, but it does not unveil if such traits are<br />

transferred onto the consumer (Russell and Stern, 2006), which is a relevant field of<br />

study as consumers have a preference for brands which are congruent with their<br />

self-concept (Dolich, 1969).<br />

The research does not account for limitations resulting from previous exposure<br />

to other marketing communications for one brand nor for the synergetic effects<br />

that might result from these (McCarthy, 2002 and Kotler, 2012): by aligning the<br />

communication objectives of the various promotional activities, a company can indeed<br />

reach better results through the synergies created across the media used.<br />

The research does not know which marketing objectives were to be achieved<br />

through product placement of the various brands. After all, marketers and media<br />

owners are not legally obliged to unveil whether or not product placement is used<br />

(Russell and Belch, 2005). It is therefore only possible to assume which meanings<br />

were desired to be transferred from a celebrity to a product (Russell and Stern,<br />

2006).<br />

The study focused on a select number of product categories. It is therefore<br />

not possible to predict the effects of product placement in different product categories,<br />

even though previous research indicated that some of the product categories<br />

used for this thesis are among the ones most used for product placement, particularly<br />

for the Czech Republic (Kramolis and Drabkova, 2012). It also does not account<br />

for differences in consumer decision making depending on the initial strength of the<br />

attitude from the consumer towards a certain category of products (Howard and<br />

Sheth, 1969).<br />

Furthermore, the study does not consider the stage in the product life cycle<br />

of the product (Foxall, Brown and Goldsmith, 1998) and whether this affects the<br />

product placement effectiveness. As such it can for instance not discern between<br />

newly-launched products and products which already exist on the market for a<br />

longer time.<br />

Though the research of this thesis attempted to recreate a real-life setting in<br />

which consumer behavior could be observed, the amount of distractions or noise
