Four Public Presentations
Friday, January 27 we are organizing four public presentations. We start with the graduation presentation of Dagmar Geerlings. Afterwards follow three lectures by our recently graduated alumni: Lise Stork, Rinus Bot and Sophie Rust.
15.00 - 15.40 Dagmar Geerlings - graduation presentation
Title: Representing Flavours with Sound - using combinations of sinewaves to represent acidic flavours
Thesis Advisors: Edwin van der Heide and Betina Piqueras Fiszman
While science has already proven sound and taste are connected, this research focusses on linking specific sounds to specific flavours. With the help of a peer group five different types of acids have been represented by combinations of sine waves. During the research participants were asked to match the acids with the sounds, in a combination test. Results show that it was relatively difficult to match the sounds with the corresponding acid, but also indicate the relationship of the representation of sound in taste is worth further research.
15:40 - 16:10 Lise Stork - lecture
Title: Deep Learning to Search for Patterns in Mental Representations?
In this research we were looking for patterns in mental representations of environments with the aid of machine learning techniques. Digital drawings, drawn by participants and representing spatial environments, were analysed by pattern recognition algorithms. Earlier research states that such drawings contain interesting information that is also in the mind. The goal was to see if psychology research would benefit from such an approach. In pscyhology research it can be difficult to develop good methods that are not influenced by the bias of the researcher regarding the outcome of the experiment. Deep learning, a pattern recognition method, has as its advantage that it is unbiased regarding the research question. One pitfall of this method however is that while the patterns found are good to do prediction with, they can be difficult to interpret and obtain new knowledge from. We will discuss what psychology could gain using pattern recognition on externalized mental representations.

Effects of Standardized Quadcopter Flight Patterns on Foraging Birds
The rapid increase in prevalence of unmanned flying drones will have animals confronted with them in unexpected ways. Study of interactions between animals and drones should be developed from a perspective of scalable data gathering. With this in mind, a case study experiment involving birds in the wild and drones is presented. It shows that in response to nearby drone flights, different species of bird react differently, and affirms usability of the proposed data gathering method.
16:40 - 17:10 Sophie Rust - lecture
Smoothened Emotions - The effect of (digital) Botox on communication
Using Botox is an increasingly popular way to prevent facial wrinkles. An effect of Botox, however, is that one’s face becomes less expressive. The aim of this research is to investigate if this effect influences communication. In an experiment two stories were communicated by a series of video messages. One group was shown video footage that had been digitally manipulated to remove the frown wrinkles, simulating the facial expressions of Botox users. The other group was shown the non-manipulated video footage. Using a ‘Chinese whisper’-setup, the stories were passed on over two generations of test subjects. Both generations were analyzed in terms of communicationloss related to the original story. For story 1 no significant differences between the Botox and non-Botox conditions were found. For story 2 there are statistically significant differences between these conditions, in particular regarding the variables ‘intended meaning’ and ‘emotion’. This may indicate that weakened facial expression due to Botox usage can lead to decreased communicative ability, in particular of emotionally-laden content.
