Evaluating Students’ Evaluations of Medical Professors: Are There Cookies?

November 9th, 2018

Prof. Dr. med. Manuel Wenk, co-author of the cookies study. The cookies were chocolate.

Some medical schools may be selecting or rejecting faculty members because those individuals do or do not offer cookies to their students. That is a possible conclusion one might draw, after reading this new study done by faculty members:

Availability of cookies during an academic course session affects evaluation of teaching,” Michael Hessler, Daniel M Pöpping, Hanna Hollstein, Hendrik Ohlenburg, Philip H Arnemann, Christina Massoth [pictured below], Laura M Seidel, Alexander Zarbock, and Manuel Wenk [pictured above], Medical Education, vol. 52, no. 10, October 2018, no. 1064-1072. The authors, at the University Hospital of Munster, Germany, report:

“Results from end-of-course student evaluations of teaching (SETs) are taken seriously by faculties and form part of a decision base for the recruitment of academic staff, the distribution of funds and changes to curricula. However, there is some doubt as to whether these evaluation instruments accurately measure the quality of course content, teaching and knowledge transfer.”

Documenting Meiji Gummy Candy Flavour-Recognition Times (new study)

November 8th, 2018

If you have ever eaten a ‘Gummy Candy’ from Meiji Co., Ltd., Tokyo, Japan, in apple, grape, orange, [European] pear, pineapple, or strawberry flavours, it may have taken you a few seconds to recognise which one you were eating. If so, you are not alone. A 2018 study published in the journal Perception sought to measure ‘Distribution of Recognition Times to Fruity Flavor of Gummy Candies in Healthy Adults’. The research team found, by experiment, that on average, healthy adults took around 7.5 seconds to be able to tell which flavour they were eating.


● The Ethics Committee of The University of Niigata Rehabilitation Graduate School approved the experiments

● The illustration shows the Meiji Gummy Sushi Candy, which did not feature in the study

● 22.7% of the participants got the flavour wrong
