Perceiving others? minds is a crucial component of social life. People do not, however, always ascribe minds to other people, and sometimes ascribe minds to non-people. This article reviews when mind perception occurs, when it does not, and why mind perception is important. Causes of mind perception stem both from the perceiver and perceived, and include the need for social connection and a similarity to oneself. Mind perception also has profound consequences for both the perceiver and perceived. Ascribing mind confers (...) an entity moral rights and also makes its actions meaningful. Understanding the causes and consequences of mind perception can explain when this most social of cognitive skills will be used, and why it matters. (shrink)

This set of seven experiments examines reasoning about the inheritance and acquisition of physical properties in preschoolers, undergraduates, and biology experts. Participants (N = 390) received adoption vignettes in which a baby animal was born to one parent but raised by a biologically unrelated parent, and they judged whether the offspring would have the same property as the birth or rearing parent. For each vignette, the animal parents had contrasting values on a physical property dimension (e.g., the birth parent had (...) a short tail; the rearing parent had a long tail). Depending on the condition, the distinct properties had distinct functions (“function-predictive”) were associated with distinct habitats (“habitat-predictive”), or had no implications (“non-predictive”). Undergraduates' bias to view properties as inherited from the birth parent was reduced in the function- and habitat-predictive conditions. This result indicates a purpose-based view of inheritance, whereby animals can acquire properties that serve a purpose in their environment. This stance was not found in experts or preschoolers. We discuss the results in terms of how undergraduates' purpose-based inheritance reasoning develops and relates to larger-scale misconceptions about Darwinian evolutionary processes, and implications for biology education.

Nominal concepts represent things as tokens of types. Recent research suggests that we represent principled connections between the type of thing something is (e.g., DOG) and some of its properties (k‐properties; e.g., having four legs for dogs) but not other properties (t‐properties; e.g., being brown for dogs). Principled connections differ from logical, statistical, and causal connections. Principled connections license (i) the expectation that tokens of the type will generally possess their k‐properties, (ii) formal explanations (i.e., explanation of the presence of (...) k‐properties in tokens of a type by reference to the type of thing it is), and (iii) normative expectations concerning the presence of k‐properties in tokens of the type. The present paper investigates the hypothesis that representing principled connections requires representing properties as aspects of being the relevant kind of thing (Aspect Hypothesis). Experiment 1 provides a direct test of the Aspect Hypothesis. Experiments 2 and 3 provide indirect tests of the Aspect Hypothesis. All three experiments provide support for the Aspect Hypothesis. Experiment 4 investigates a prediction of the Aspect Hypothesis concerning the manner in which formal explanations are licensed by principled connections. Finally, Experiment 5 investigates a prediction of the Aspect Hypothesis concerning the nature of the normative expectations licensed by principled connections. Together these results provide strong evidence for the idea that representing principled connections involves representing a property as being an aspect of being a given kind of thing. The results also help clarify the manner in which formal explanation differs from other modes of explanation. Finally, the results of the experiments are used to motivate a proposal concerning the formal structure of the conceptual representations implicated by principled connections. This structure provides a domain‐general way of structuring our concepts and embodies the perspective we take when we think and talk of things as being instances of a kind. (shrink)

In his article “The Ontology of Musical Versions: Introducing the Hypothesis of Nested Types,” Nemesio Puy raises a hypothesis that continuity of the purpose is both a necessary and a sufficient condition for musical work’s identity. Puy’s hypothesis is relevant to two topics in cognitive psychology and experimental philosophy. The first topic is the prevalence of teleological reasoning about various objects and its influence on persistence and categorization judgments. The second one is the importance of an artist’s intention in the (...) categorization of artworks. We tested the teleological hypothesis across three studies. Vignettes in these three studies describe a musical work being changed in some of these aspects: purpose either changed or retained; score either changed or retained; change is made either by the same or a different composer. The results suggest that teleological considerations impact judgments on the persistence of musical works, but this impact appears to be relatively weak. The results also suggest that persistence judgments strongly depend on whether acoustical properties were changed, while whether the change was made by the original composer seems to be relatively unimportant.
