It's long-established knowledge that sensory input triggers both cortical event-related potentials (ERPs) responding to the contextual congruity and expectedness of the input's specific values, as well as affective responses that attribute those values (or the summed set of them) with a particular valence.
What is known as to whether these disparate responses have a causal bearing on each other, and, if so, what the effects of their interplay are and what the immediate downstream consequences might be for executive control processes (especially attention and working memory) , motor response selection, and subsequent cognitive learning or updating?
Dear Richard,
I'm not quite sure if I understood your question.
Are you asking about findings of the influence of affective valence on event related potentials? There are quite a number of papers on this subject.
See for example:
Keil, J., Adenauer, H., Catani, C., Neuner, F., 2009. Imaging cortical activity following affective stimulation with a high temporal and spatial resolution. BMC Neurosci 10, 83. doi:10.1186/1471-2202-10-83
Keil, A., Gruber, T., Müller, M.M., Moratti, S., Stolarova, M., Bradley, M.M., Lang, P.J., 2003. Early modulation of visual perception by emotional arousal: evidence from steady-state visual evoked brain potentials. Cogn Affect Behav Neurosci 3, 195–206.
Keil, A., Ihssen, N., Heim, S., 2006. Early cortical facilitation for emotionally arousing targets during the attentional blink. BMC Biol 4, 23. doi:10.1186/1741-7007-4-23
Please correct me, if I misunderstood your question.
Cheers,
Julian
Dear Julian,
Very many thanks for your reply - and yes, you've interpreted my question absolutely correctly. The papers you've so kindly listed, reporting your own research, are thoroughly relevant and informative for the questions I'm pursuing and most exciting to read. Together with their cited references, they provide me with an excellent portal to this field - I'm truly grateful to you.
To amplify my posted question a little, very briefly my personal interest centres in understanding neural mechanisms mediating the percept-action cycle and ideomotor (action/action-effect) coupling, as foundations for developing methodology aimed at improving student instrumentalists' cultivating, memorizing and use of auditory imagery for promoting cognitive and motor expertise. As Damasio stresses, an integrated view of the nervous system's functional architecture and its mechanisms' collaborative activity is impossible without including those mediating emotion and its roles in memory formation and retrieval, goal-setting and goal-directed decision-making. Localized and temporally sequenced cortical potentials correlating with activity in emotional mechanisms are essential for understanding those roles in relation to the percept-action cycle and ideomotor activity, and the essentiality of their general role as generators of somatic markers indexing cortical representations of the world relatively to internal states.
While your papers concern emotional effects of presented visual stimuli on cortical potentials, I would venture the guess that certain of your findings pertain also to auditory stimuli. Would you agree? Has much research on that been done to date?
Many thanks again!
Richard
Dear Richard,
I personally have not done any research on the emotional valence of auditory stimuli. If I recall correctly, there is a database on affective sounds, similar to the IAPS database for pictures, but I'm not sure. With respect to research on the influence of emotional stimuli on cortical responses, I think most work centers on startle responses, which is probably not what you are looking for.
However, I agree with you that most findings from the visual domain should also translate to the auditory domain. Maybe the work of Isabelle Peretz at the Université de Montréal (http://www.peretzlab.ca/) or her colleagues at the International Laboratory for Brain, Music and Sound Research (http://www.brams.org/) can be more helpful to you.
Cheers,
Julian
