DO WE SENSE MODALITIES WITH OUR SENSE MODALITIES?1

It has been widely assumed that we do not perceive dispositional properties. I argue that there are two ways of interpreting this assumption. On the first, extensional, interpretation whether we perceive dispositions depends on a complex set of metaphysical commitments. But if we interpret the claim in the second, intensional, way, then we have no reason to suppose that we do not perceive dispositional properties. The two most important and influential arguments to the contrary fail.     

A Systematic Scoping Review of the Choice Architecture Movement: Toward Understanding When and Why Nudges Work

In this paper, we provide a domain‐general scoping review of the nudge movement by reviewing 422 choice architecture interventions in 156 empirical studies. We report the distribution of the studies across countries, years, domains, subdomains of applicability, intervention types, and the moderators associated with each intervention category to review the current state of the nudge movement. Furthermore, we highlight certain characteristics of the studies and experimental and reporting practices that can hinder the accumulation of evidence in the field. Specifically, we found that 74% of the studies were mainly motivated to assess the effectiveness of the interventions in one specific setting, while only 24% of the studies focused on the exploration of moderators or underlying processes. We also observed that only 7% of the studies applied power analysis, 2% used guidelines aiming to improve the quality of reporting, no study in our database was preregistered, and the used intervention nomenclatures were non‐exhaustive and often have overlapping categories. Building on our current observations and proposed solutions from other fields, we provide directly applicable recommendations for future research to support the evidence accumulation on why and when nudges work.

Perception is not all-purpose

I aim to show that perception depends counterfactually on the action we want to perform. Perception is not all-purpose: what we want to do does influence what we see. After clarifying how this claim is different from the one at stake in the cognitive penetrability debate and what counterfactual dependence means in my claim, I will give a two-step argument: (a) one’s perceptual attention depends counterfactually on one’s intention to perform an action (everything else being equal) and (b) one’s perceptual processing depends counterfactually on one’s perceptual attention (everything else being equal). If we put these claims together, what we get is that one’s perceptual processing depends counterfactually on one’s intention to perform an action (everything else being equal).

     

Perception and imagination: amodal perception as mental imagery

When we see an object, we also represent those parts of it that are not visible. The question is how we represent them: this is the problem of amodal perception. I will consider three possible accounts: (a) we see them, (b) we have non-perceptual beliefs about them and (c) we have immediate perceptual access to them, and point out that all of these views face both empirical and conceptual objections. I suggest and defend a fourth account, according to which we represent the occluded parts of perceived objects by means of mental imagery. This conclusion could be thought of as a (weak) version of the Strawsonian dictum, according to which “imagination is a necessary ingredient of perception itself”.     

Studying the role of cognitive control in reasoning: evidence for the congruency sequence effect in the ratio-bias task

In this study, we investigated whether control of the conflict between incongruent heuristic and analytical answer options in a reasoning task is modulated by the presence of conflict on previous trials. In two experiments, we found that the incongruency of the previous trial has a significant effect on the control exhibited on the current trial. Our data also showed that this adaptation effect is modulated by the incongruency of the previous series of trials. These results demonstrate the same control adaptation effects for a reasoning task as observed for standard response interference tasks. Coinciding control effects in the two research areas suggest that cognitive control might be an important mechanism underlying performance on reasoning tasks. Based on these results we argue that the study of cognitive control in reasoning could potentially facilitate the refinement of empirical predictions and provide a new tool to explore the exertion of top-down control in human thinking.     

What did Popper learn from Lakatos?

The canonical version of the history of twentieth century philosophy of science tells us that Lakatos was Popper’s disciple, but it is rarely mentioned that Popper would have learned anything from Lakatos. The aim of this paper is to examine Lakatos’ influence on Popper’s philosophical system and to argue that Lakatos did have an important, yet somewhat unexpected, impact on Popper’s thinking: he influenced Popper’s evolutionary model for ‘progress’ in science. And Lakatos’ influence sheds new light on why and how Popper continually revised one of the central claims of his philosophy of science: the evolutionary account of scientific theory change.     

Perceiving pictures

I aim to give a new account of picture perception: of the way our visual system functions when we see something in a picture. My argument relies on the functional distinction between the ventral and dorsal visual subsystems. I propose that it is constitutive of picture perception that our ventral subsystem attributes properties to the depicted scene, whereas our dorsal subsystem attributes properties to the picture surface. This duality elucidates Richard Wollheim’s concept of the “twofoldness” of our experience of pictures: the “visual awareness not only of what is represented but also of the surface qualities of the representation.” I argue for the following four claims: (a) the depicted scene is represented by ventral perception, (b) the depicted scene is not represented by dorsal perception, (c) the picture surface is represented by dorsal perception, and (d) the picture surface is not necessarily represented by ventral perception.

Threefoldness

Theories of picture perception aim to understand our perceptual relation to both the picture surface and the depicted object. I argue that we should talk about not two, but three entities when understanding picture perception: (A) the picture surface, (B) the three dimensional object the picture surface visually encodes and (C) the three dimensional depicted object. As (B) and (C) can come apart, we get a more complex picture of picture perception than normally assumed and one where the notion of twofoldness, which has played an important albeit controversial role in understanding picture perception is replaced by the concept of threefoldness.
