Theory of Mind: A Neural Prediction Problem (2013, positive): “Predicted Stimuli Elicit Reduced Activity with Sharpened Representations Kok et al. (2012a) report that an accurate prediction led to reduced response amplitude in early visual cortex, but also simultaneously to an “improved” stimulus representation, as measured by multi-voxel pattern analysis.”
How Do Expectations Shape Perception? (2018, positive): “Such studies showed for instance that expectation suppression in macaque IT was associated with decreased decoding performance [66]; that BOLD responses in posterior superior temporal sulcus (pSTS) to expected words were weaker and contained less information, as quanti ﬁ ed by representational simil”
How Prediction Errors Shape Perception, Attention, and Motivation (2012, positive): “Remarkably, there is a robust cortical response to such surprising stimulus omissions in the relevant sensory cortical areas (den Ouden et al., 2009; Todorovic et al., 2011; Wacongne et al., 2011; Kok et al., 2012b).”
Repetition Suppression and Expectation Suppression Are Dissociable in Time in Early Auditory Evoked Fields (2012, positive): “Further empirical support for this scheme is provided by a recent study that showed that expected visual stimuli lead to attenuated neural activity, yet improve the fidelity (sharpness) of the sensory representation in the primary visual cortex (Kok et al., 2012a).”
Oscillatory entrainment to our early social or physical environment and the emergence of volitional control (2022, unknown): “When considering physiological responsiveness, an additional challenge is that one system (the Autonomic Nervous System) is responsible for responding both to positive, attention-eliciting stimuli and to negative, aversive stimuli (Kok et al., 2012; Stevens et al., 2009).”
