We have a PhD position in Cognitive Neuroscience on "The Influence of Predictions on the Mechanisms of Conscious Perception" available at the Conscious Brain Lab (https://t.co/L1valwAzaQ) at the University of Amsterdam: https://t.co/O9SFomOJio
The template for cognitive neuroscientific progress:
1. It's one system
2. It's two systems
3. The two systems are actually one system
4. There are two but they extensively & dynamically interact
5. We have no idea how it works
@weilnhammer@m_guggenmos Thanks Veith! Such a rigorous exciting piece of work. Need to properly delve into the supplement. I was just fascinated by the stimulus video, noticing how I am waiting for the switch to finally occur, kind of ramping up my expectations.
@hsinghaolee @kaiserdaniel13 @jjfahrenfort this one is quite similar, just used it for teaching distinctions between different properties of emotion states (adopting the framework by Adolphs and Anderson 2018): https://t.co/KTpgyT7YzE
Publication alert! Differences in unconscious processing of subjectively vs. objectively invisible faces and houses in visual cortex. IMHO also the first evidence that fMRI can discriminate fully indiscriminable stimuli

It is often thought that psychopaths act as they do because they fail to perceive fear. Testing a rather large sample of violent offenders in prison with continuous flash suppression we found no evidence for such fear blindness in psychopathy: https://t.co/1AX1TWaf0F @Aiste_Jus
@Renzo_Lanfranco @Aiste_Jus I know, I remember this paper too well, and our struggle with a reviewer who claimed that our inverted, contrast-reversed eye regions still differed in dominance although people failed to rate these stimuli on dominance: https://t.co/pOmvnSXflf
@Renzo_Lanfranco @Aiste_Jus Yes, that's an excellent point but I think one can argue that psychopaths would not be sensitive to fear-defining low-level features if basic fear perception was impaired. More generally, the concern would apply to most studies using fearful expressions.
@hsinghaolee @Aiste_Jus Oh, we didn't - we only equated mean luminance and SD contrast. This is really just a follow-up (and equivalent to) Yang 2007, and the effect is most likely reflecting visual factors rather than emotional meaning.
@SuryaGayet @kaiserdaniel13 @jjfahrenfort 🙏 thanks Surya! i feel obj inv was robust only in LOC and so i would suspect reliable patterns there for stimulus categories with clear visual (shape) differences
The extent of unconscious information processing in human #VisualCortex is determined by the measurement approach; only subjectively, but not objectively, invisible stimuli are represented at a categorical level @realTimoStein &co #PLOSBiology https://t.co/JFWvkuTGLw
@AbirYaniv@clava_phd@NatureHumBehav@MariusPeelen@UvA_Amsterdam Good point! I included several "transparency ramps", and effects differed between ramps but we didn't preregister these analyses (https://t.co/wqgJEVIy3f). FIE was smaller than usual but the bubu-kiki effect was actually the same size as in the CFS replication by @pieter_moors
New paper "Dissociating conscious and unconscious influences on visual detection effects" out in @NatureHumBehav today: https://t.co/BX5xkxrQGZ
We introduce a new way to study unconscious perception @MariusPeelen@UvA_Amsterdam
@AbirYaniv@clava_phd@NatureHumBehav@MariusPeelen@UvA_Amsterdam It worked quite well! Although effect sizes for the face-inversion effect were much smaller than with CFS and BM, as far as I can tell. We're now trying to run RMS in an accuracy-based fashion (no RTs) -- will let you know when we're wrapping this up :)
