New paper: Search Process as Transitions Between Neural States

Frank Pollick will present his new research with Yashar Moshfeghi at the World Wide Web Conference in Lyon. This is part of the ongoing research collaboration joining together cognitive neuroscience and information retrieval/data science approaches to understand search.

Abstract
Search is one of the most performed activities on the World Wide Web. Various conceptual models postulate that the search process can be broken down into distinct emotional and cognitive states of searchers while they engage in a search process. These models significantly contribute to our understanding of the search process. However, they are typically based on self-report measures, such as surveys, questionnaire, etc. and therefore, only indirectly monitor the brain activity that supports such a process. With this work, we take one step further and directly measure the brain activity involved in a search process. To do so, we break down a search process into five time periods: a realisation of Information Need, Query Formulation, Query Submission, Relevance Judgment and Satisfaction Judgment. We then investigate the brain activity between these time periods. Using functional Magnetic Resonance Imaging (fMRI), we monitored the brain activity of twenty-four participants during a search process that involved answering questions carefully selected from the TREC-8 and TREC 2001 Q/A Tracks. This novel analysis that focuses on transitions rather than states reveals the contrasting brain activity between time periods – which enables the identification of the distinct parts of the search process as the user moves through them. This work, therefore, provides an important first step in representing the search process based on the transitions between neural states. Discovering more precisely how brain activity relates to different parts of the search process will enable the development of brain-computer interactions that better support search and search interactions, which we believe our study and conclusions advance.

7th CERE conference!

CERE 2018 hosted by Rachael Jack at the University of Glasgow was a huge success! Over 300 emotion researchers in attendance, 27 countries represented, 2 full days of fantastic keynotes, symposia, talks, and posters. Thank you to the CERE community and all of Team CERE who made this a roaring success.

7th Consortium of European Research on Emotion

We are hosting the 7th Consortium of European Research on Emotion (CERE) Conference here at The University of Glasgow on 4-5 April 2018.

CERE 2018: April 4-5, 2018, Glasgow, Scotland (UK)

CERE is an informal organisation that promotes research across Europe among scholars from a wide range of disciplines with an interest in the topic of emotion.

We’ll be hosting 300+ emotion researchers from an international and multidisciplinary academic community who will be presenting the latest in emotion research. Our program will include 2 international keynote speakers – Prof. Batja Mesquita and Prof. Stacy Marsella –  17 symposia, 78 talks, 150+ posters. Our sponsors Dimensional Imaging  will also be presenting their latest technology. http://www.di4d.com/
