Multimodality of Affect

Research output: Contribution to conferencePosterCommunication

It has been proposed that affective processes could be better understood by applying dynamical systems theory to their modelling. For this purpose, emotional processes can be inspected on three self-organizing time-scales: on micro-, meso and macro levels. A gap in the empirical research of affect-related processes has been recognized in particular on the micro level, which represents the highest temporal resolution. Also, there exists a need to address emotional processes in relation to other anatomical regions than the sub-cortical brain areas, as well as in relation to sensory multimodality. This study compares patterns of activation in the visual and auditory cortices during perception of emotional, visual and auditory stimuli when primed with a stimulus from the opposing sensory domain.
Research questions
Is there an interaction effect between visual and auditory cortices in relation to the primer modality (visual vs. auditory) and emotional arousal-valence dimension (low vs. high)? Are behavioural priming effects manifested differently depending on the target-primer combination?
An affective priming paradigm with MEG was used to measure whether semantically meaningful emotional pictures and sounds can be used to prime the pleasantness judgement of musical chords and of black and white visual patterns. MEG (evoked field) and behavioural responses (reaction times) were measured in 20 healthy adult participants.
The data collection has been completed and analysis will be finished by May 2018. It is hypothesized that the pleasantness judgements of the auditory stimuli will be primed, as indexed by a shorter response latency and modification of the late ERPs in particular. It is also expected that affective judgement of the visual stimuli would rely mainly on spontaneous feature analysis of the patterns, thus being less susceptible to priming effects than the judgment of the auditory stimuli.
