Modes of presentation (MOPs) are often said to have to be transparent, usually in the sense that thinkers can know solely via introspection whether or not they are deploying the same one. While there has been much discussion of threats to transparency stemming from externalism, another threat to transparency has gar- nered less attention. This novel threat arises if MOPs are robust, as I argue they should be according to internalist views of MOPs which identify them with represen- tational vehicles, (...) such as mental files. I explain how identifying MOPs with vehicles/files threatens trans- parency, provide empirical illustrations, and critically examine some attempts to dispel the threat. Rather than abandoning transparency, I outline a way of reconciling it with a robust view of mental files which takes seriously the idea that they are targets for investigation in cogni- tive science. Transparency does not require introspective access, and rather than as an incontrovertible principle for individuating MOPs, we can view it more modestly, as an open empirical hypothesis. (shrink)

Many philosophers hypothesize that our concept of personal identity is partly constituted by the one-person-one-place rule, which states that a person can only be in one place at a time. This hypothesis has been assumed by the most influential contemporary work on personal identity. In this paper, we report a series of studies testing whether the hypothesis is true. In these studies, people consistently judged that the same person existed in two different places at the same time. This result undermines (...) some widely held philosophical assumptions, supports others, and fits well with recent discoveries on identity judgments about inanimate objects and non-human animals.

Our aim in this entry is to articulate the state of the art in the moral psychology of personal identity. We begin by discussing the major philosophical theories of personal identity, including their shortcomings. We then turn to recent psychological work on personal identity and the self, investigations that often illuminate our person-related normative concerns. We conclude by discussing the implications of this psychological work for some contemporary philosophical theories and suggesting fruitful areas for future work on personal identity.

The way in which vision represents objects as being the same despite movement and qualitative changes has been extensively investigated in contemporary psychology. However, the formal properties of the visual sameness relation are still unclear, for example, whether it is an identity-like, equivalence relation. The paper concerns one aspect of this problem: the transitivity of visual sameness. Results obtained by using different experimental paradigms are analysed, in particular studies using streaming/bouncing stimuli, multiple object tracking experiments and investigations concerning object-specific preview (...) benefit, and it is argued that the transitive interpretation of visual sameness is the most plausible given the current stage of knowledge. What is more, it is claimed that the way in which visual sameness is represented suggests that in some cases it should be characterized as a “primitive sameness”, similarly as in philosophical theories postulating “thisness”.

Within cognitive psychology it is widely accepted that the human visual system represents the numerical sameness of objects. However, the relation of visual sameness itself has not attracted as much attention and no detailed description of this relation is yet available. One of the most important questions is whether this relation can be understood as classical identity, and thus whether it is an equivalence relation. Despite this research gap, I intend to show that results of some psychological works can be (...) interpreted as having a high relevance for the question of equivalence. I demonstrate this by analyzing a study by Drew et al. (2013). (shrink)
