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

@Renzo_Lanfranco But I just don't understand why he agreed to test his theory with an inadequate design in the first place? (no unconscious condition)

@jjfahrenfort @VictorLamme @hakwanlau @AndrewHaun3 I like protein chauvinism!

[Gregory Hickok @GregoryHickok]

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

@KathaSchmack @TheCrick amazing!! congratulations!!🎉🖤 are you accepting interns...?

[Timo Stein @realTimoStein]

@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

[Timo Stein @realTimoStein]

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

@Renzo_Lanfranco @Aiste_Jus yeah that would be nice but not easy to do in the prison setting :)

[Timo Stein @realTimoStein]

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

[Timo Stein @realTimoStein]

@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

[Timo Stein @realTimoStein]

@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.

[Timo Stein @realTimoStein]

@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.

[Timo Stein @realTimoStein]

@SuryaGayet @kaiserdaniel13 @jjfahrenfort oh i am not at VSS...

[Timo Stein @realTimoStein]

@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

[PLOS Biology @PLOSBiology]

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

@lajnd Buzzfeed goes academic publishing

[Timo Stein @realTimoStein]

@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

[Timo Stein @realTimoStein]

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

[Timo Stein @realTimoStein]

@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 :)
