Lindquist et al. provide a compelling summary of the brain bases of the onset of emotion. Their conclusions, however, are constrained by typical fMRI techniques that do not assess a key ingredient in emotional experience – timing. We discuss the importance of timing in theories of emotion as well as the implications of neural temporal dynamics for psychological constructionism.

Rachlin overlooks that free will determines when and in what direction acts that appear impulsive will occur. Because behavioral patterns continuously evolve, animals are not guaranteed when they will, or how to, maximize larger-later reinforcements. An animal therefore uses self-control to emit free acts to vary behavioral patterns to optimize larger-later rewards.

we have found that the left side of faces displayed in rembrandt's portraits capture how humans rank male dominance, helping to coordinate avoidance behaviors among asymmetric individuals. moreover, the left side of faces may also coordinate approach responses, like attractiveness, in human females. therefore, adding sexual selection to dominance paints a more realistic picture of what the contralateral right hemisphere is doing.

Collapsing three-dimensional space into two violates Lehar's “volumetric mapping” constraint and can cause the visual system to construct illusory transparent regions to replace voxels that would have contained illumination. This may underlie why color constancy is worse in two dimensions, and argues for Lehar to revise his phenomenal spatial model by putting “potential illumination” in empty space.

Two cross-modal experiments provide partial support for O'Regan & Noë's (O&N's) claim that sensorimotor contingencies mediate perception. Differences in locating a target sound accompanied by a spatially disparate neutral light correlate with whether the two stimuli were perceived as spatially unified. This correlation suggests that internal representations are necessary for conscious perception, which may also mediate sensorimotor contingencies.

A biological neuroscientific theory must acknowledge that the function of a neurological system is to produce behaviors that promote survival. Thus, unlike what Gold & Stoljar claim, function and behavior are the province of neurobiology and cannot be relegated to the field of psychological phenomena, which would then trivialize the radical doctrine if accepted. One possible advantage of adopting such a (correctly revised) radical doctrine is that it might ultimately produce a successful, evolutionarily based, theory of mind.

Pylyshyn's concentration on form perception to demonstrate that early vision is cognitively impenetrable neglects that color perception is also part of early vision. Thus, the finding of Duncker (1939), Bruner et al. (1951), and Delk and Fillenbaum (1965) that the expected color of objects affects how they are perceived challenges Pylyshyn's thesis.
