Could you provide me with information about how the nine subscales of the SPQ correlate with neural response during social cognition tasks? Any reference paper would be of great help.
On the whole, I want to say that this is going to be the topic of your dissertation - and I look forward to reading a published version of it! You'll probably have more luck looking for articles that address this in bits and pieces: schizotypal people (however assessed) performing social cognition tasks, schizotypal people having brain activity measured, and so on. But here is one reference that may help: Rapp, A.M. et al. (2013). Isn't it ironic? Neural correlates of irony comprehension in schizophrenia. PLoS ONE, 8(9)
A helpful startpoint may be:
Asai, Tomohisa, et al. "The hierarchic structure in schizotypy and the five-factor model of personality." Psychiatry research 185.1 (2011): 78-83.
other starting points might be: Sugraynes et al. Autism spectrum disorders and schizophrenia: analysis of the neural correlates of social cognition, PLoS one 2011 and Corlett and Fletcher: The neurobiology of schizotypy: fronto-striatal prediction error signal correlates with delusion-like beliefs in healthy people 2012. Neuropsychologia
You may ask the authors for more details or request their raw data!
Good luck
thank you very much for your interesting input! I already read the papers of Asai et al. (2011) and Rapp et al. (2013) and they're of great value to my work.
Thank you Gerit Pful for your suggestions, I guess that especially the paper of Corlett may fit well into my research topic.
You might find it interesting to look at correlates of yawning. Yawning, like laughter, is contagious social behavior. Some researchers view yawning as a signaling tool for group cohesion. Humans tend to yawn during periods of transition (awakening, going to bed, before/after major events, when bored, etc). See olympic athletes prior to competition, observe yourself when you are eager to exit a social gatherig, think of the meaning yawning conveys when two people are on a first date. Similarly, many animals yawn in mass before events (moving on, fighting, going to sleep).
Laughter, too, has a very large social component. People laugh in predictable ways that are probably neurologically hard-wired. (people laugh at phrase breaks in speech, not during speech; speakers laugh more than their audiences; laugh-eliciting statements are almost entirely non-humorous, etc.).
Some research has indicated that individuals with autism do not respond to laughter with contagoius recriprocation, and at least two studies have demonstrated that individuals with schizophrenia and schizotypal personality features tend to yawn infrequently.
So, if yawning and laughter are social signals, and the construct of schizotypal personality disorder necessarily has a large social component, you might want to think about exploring these issues in your study.
See the work of Robert R. Provine as a start. He has a book on laughter Laughter: a scientific investigation (2000) and one on a variety of stereotyped behavior Curious Behavior (2012). These books might stimulate some ideas.
My colleagues and I have just sent for review a paper that maps SPQ onto a large genetic (1000 subjects) dataset with a view to understanding the possible neural substrates. I would be happy to share the manuscript with you shortly.
Dear simon, I guess we all would be very interested in your ms. Pls let me know when you can send it!
I would suggest to read the wsork of Rutger Goekoop: Research project:
"Localization of the structural and functional correlates of multidimensionally defined personality traits - a combined MRI and fMRI study":
http://www.rgoekoop.dds.nl/page4.html
Dear Stefaan,
thank you for your very interesting suggestion, I did not consider the work of Rutger Goekoop yet but I think it fits pretty much!
