BOLD response to motion verbs in left posterior middle temporal gyrus during story comprehension

A primary focus within neuroimaging research on language comprehension is on the distribution of semantic knowledge in the brain. Studies have shown that the left posterior middle temporal gyrus (LPMT), a region just anterior to area MT/V5, is important for the processing of complex action knowledge. It has also been found that motion verbs cause activation in LPMT. In this experiment we investigated whether this effect could be replicated in a setting resembling real life language comprehension, i.e. without any overt behavioral task during passive listening to a story. During fMRI participants listened to a recording of the story “The Ugly Duckling”. We incorporated a nuisance elimination regression approach for factoring out known nuisance variables both in terms of physiological noise, sound intensity, linguistic variables and emotional content. Compared to the remaining text, clauses containing motion verbs were accompanied by a robust activation of LPMT with no other significant effects, consistent with the hypothesis that this brain region is important for processing motion knowledge, even during naturalistic language comprehension conditions.     

How trust in financial supplier information impacts young adults' financial information involvement: The moderating roles of product savings risk and social norm

Although consumers' risk‐taking, supplier trust, social norms and information involvement are central to much of thought in the financial market and consumer economic literature, it is not known how the interplay between consumers' trust in supplier information, risk‐taking behaviour and social norm may influence information involvement. This research contributes to the consumer economic literature by investigating how product savings risk and social norm affect the relationship between young adults' trust in supplier information and their information involvement. On the basis of two samples with young adults who recently have purchased a low‐risk savings product (n = 641) and a high‐risk savings product (n = 219), respectively, several results are obtained. It is found that both product savings risk and social norm positively moderate the relationship between young adults' trust in supplier information and their information involvement. In addition, the results indicate that the three‐way interaction between trust in supplier information, products savings risk and social norm has a positive effect on information involvement. As direct implications, financial authorities and financial service managers should especially consider investing additional resources in developing information trust for high‐risk savings products and should also take social norms into account when considering young adults' high‐risk‐taking behaviour.
