Constitutive strata and the dorsal stream

In his paper, “The Dorsal Stream and the Visual Horizon,” Michael Madary argues that “dorsal stream processing plays a main role in the spatiotemporal limits of visual perception, in what Husserl identified as the visual horizon” (Madary 2011, p. 424). Madary regards himself as thereby providing a theoretical framework “sensitive to basic Husserlian phenomenology” (Madary 2011). In particular, Madary draws connections between perceptual anticipations and the experience of the indeterminate spatial margins, on the one hand, and the Husserlian spatiotemporal visual horizons, on the other. I argue that Madary’s arguments, for a Husserlian view of the two visual systems, are not convincing. When the notion of visual horizon is adequately understood as a constitutive notion, there will be reason to regard the connections between dorsal processing and the Husserlian spatiotemporal horizons as tenuous at best.     

Fears as Conscious Perceivings

Peter Goldie has argued for the view that the intentionality of emotions is inseparable from their phenomenology (IPE), but certain criticisms have revealed his argument as problematic. I will argue that it is possible to address these problems, at least in the case of the emotion of fear, thereby vindicating IPE, by appeal to a Husserlian version of the perceptual account of emotions, centered on the idea that the contents of perceptual experiences are fulfillment conditions. Fulfillment means the achievement of a kind of immediate, or “full”, experience of an object or some of its aspects. In the case of visual perception, suppose you are looking at an apple. If you turn it around, you will find yourself in full view of its back side, which was previously anticipated “emptily”, fulfilling or disappointing (confirming or disconfirming) some of your anticipations in regard to it. On the Husserlian view, the success or failure of a visual perceptual experience consists in such fulfillments and disappointments. If we can provide an account of the intentionality of emotions along similar lines, it will necessarily involve the phenomenal contrast between fullness and emptiness, enabling us to support IPE.     

Recall is not necessary for verbal sequence learning

The question of whether overt recall of to-be-remembered material accelerates learning is important in a wide range of real-world learning settings. In the case of verbal sequence learning, previous research has proposed that recall either is necessary for verbal sequence learning (Cohen & Johansson Journal of Verbal Learning and Verbal Behavior, 6, 139–143, 1967; Cunningham, Healy, & Williams Journal of Experimental Psychology: Learning, Memory, and Cognition, 10, 575–597, 1984), or at least contributes significantly to it (Glass, Krejci, & Goldman Journal of Memory and Language, 28, 189–199, 1989; Oberauer & Meyer Memory, 17, 774–781, 2009). In contrast, here we show that the amount of previous spoken recall does not predict learning and is not necessary for it. We suggest that previous research may have underestimated participants’ learning by using suboptimal performance measures, or by using manual or written recall. However, we show that the amount of spoken recall predicted how much interference from other to-be-remembered sequences would be observed. In fact, spoken recall mediated most of the error learning observed in the task. Our data support the view that the learning of overlapping auditory–verbal sequences is driven by learning the phonological representations and not the articulatory motor responses. However, spoken recall seems to reinforce already learned representations, whether they are correct or incorrect, thus contributing to a participant identifying a specific stimulus as either “learned” or “new” during the presentation phase.
