We are seeking two postdocs for positions using computational methods to examine nonverbal vocalisations, like laughing, screaming, and crying. The project will include the development of a novel approach to understanding everyday nonverbal behaviours using computational methods. As well as being hosted in the supportive research atmosphere of the Department of Social Psychology at the University of Amsterdam, the postdocs will have the opportunity to establish research connections with international collaborators.
The postdocs will conduct their research under the supervision of Dr Disa Sauter at the University of Amsterdam. Postdoc position 1 will be co-supervised by Professor Florian Huber (Düsseldorf University of Applied Sciences). The postdocs will engage with Sauter’s research group as part of her NWO-funded Vici project Understanding nonverbal vocalisations: A computational ethology approach. The projects will also be embedded within the Amsterdam Interdisciplinary Centre for Emotion.
The positions include allowances for research expenses and travel and subsistence costs towards project-specific travel, including conferences. It also offers an opportunity to gain experience with teaching, subject to availability and qualifications.
The Department of Social Psychology is supported by approximately 15 tenured faculty members, and currently hosts more than 20 PhD and postdoctoral researchers. We offer a dynamic environment in an internationally recognized department, ranking among the best in Europe for research and teaching. This is paired with an informal and supportive atmosphere. Amsterdam is an international city, consistently ranked as one of the world’s top places to live.
The Psychology Department is situated centrally in Amsterdam, and hosts program groups focusing on social, organisational, developmental, clinical, statistical, and cognitive psychology. It offers excellent facilities for undertaking research in a broad range of areas, including behavioural testing suites and a social observation lab.
The Department of Psychology is a part of the Faculty of Social and Behavioural Sciences (FMG), which is the largest educational and research institution in the social sciences in the Netherlands. The faculty serves 7500 students in numerous Bachelor and Master programs.
What are you going to do
The overarching aim of this project is to establish what nonverbal vocalisations are and why they occur. The two postdoc positions will use complementary methods to study this research question; a PhD student will work on another part of the research program.
Postdoc position 1
The goal of this project is to take a large-scale approach to investigating when and why vocalizations occur. The project will make use of existing videos from online sources (e.g., YouTube, TikTok, Youku, news footage, documentaries). Data analysis and machine-learning techniques will be used to (largely) automate the isolation of vocalisations from the data. In parallel, the context will be established based on the online videos. Already collected vocalisations will be converted into spectrographic representations and used to train a deep learning algorithm (e.g., convolutional neural network, CNN), to detect nonverbal vocalisations in the online videos. The vocalisation segments of the videos will then be filtered and segmented using state-of-the-art software like pyAudioAnalysis. The situational features will be automatically determined using the Google Video Intelligence API or similar. This project will test the mappings between vocalisations and contextual information in a large dataset of online videos.
You will
- develop new methods for the isolation and extraction of vocalisations from online video
- run acoustic analyses
- conduct large-scale computational analyses (e.g., using deep learning as well as data visualization techniques )
- write scientific articles and present
Postdoc position 2
The goal of this project is to provide an unbiased account of nonverbal vocalisations, including their absolute and relative frequency, as they occur in daily life. It will also establish the role of learning for different kinds of non-verbal vocalisations. The project will use the EAR, an audio-recording mobile phone app that intermittently samples the wearer’s auditory environment. EAR recordings will be combined with experience sampling data, collected using a mobile phone setup at timepoints synchronised to the EAR recordings. The project will include a general population sample, as well as a sample of deaf individuals, in order to establish the extent to which different kinds of vocalisations are dependent on particular kinds of environmental input to develop.
You will
- develop an EAR/ESM study protocol
- recruit participants, including deaf individuals
- run acoustic analyses
- conduct computational analyses (e.g., using machine learning techniques)
- write scientific articles and present
