The Institute of Philosophy (IFS) from CSIC presented the results of three in-depth interviews that were conducted with Spanish speaking individuals who had previously completed a survey as part of a larger, 3-country/language, survey on BCI perceptions. 11 out of 15 of these Spanish respondents (survey) either strongly or somewhat accept the use of BCI in rehabilitation therapy. However, in-depth interviews conducted with these Spanish rehabilitation professionals indicate that they would not apply BCI technologies due to a lack of knowledge about its ethical, legal and social implications.
