The ‘standard picture of meaning’ suggests that natural languages are composed of two different kinds of words: concrete words whose meaning rely on observable properties of external objects and abstract words which are essentially linguistic constructs. In this study, we challenge this picture and support a new view of the nature and composition of abstract concepts suggesting that they also rely to a greater or lesser degree on body-related information. Specifically, we support a version of this new view which we (...) call “x-ception theory” maintaining that abstract concepts are based on internal information of a proprioceptive, interoceptive and affective kind. Secondly, we address a methodological issue concerning the so-called concreteness and imageability measures, two tools that are widely used in (mainly psycholinguistic) empirical research to assess the degree of concreteness of specific words. On the basis of this analysis we argue that—even though the classical concreteness and imageability measures were developed in relation to the standard picture of meaning—they can also be used in the new framework of x-ception theory. In particular, we suggest that the discrepancy between these two measures provides a clue as to whether a word relies on internal information. By contrast, we argue that a new measure for concreteness recently proposed in order to address some problems with the old measure is completely inappropriate for this aim. (shrink)

This study addresses the issue of artifact kinds from a psychological and cognitive perspective. The primary interest of the investigation lies in understanding how artifacts are categorized and what are the properties people rely on for their identification. According to a classical philosophical definition artifacts form an autonomous class of instances including all and only those objects that do not exist in nature, but are artificial, in the sense that they are made by an artĭfex. This definition suggests that artifacts (...) are classified primarily on the basis of the recognition of their artificial nature. Nevertheless, many psychological and cognitive studies maintain that artifacts are categorized mainly on the basis of the recognition of the function they have been made to accomplish. Since tools are also categorized primarily on the basis of their function, this would imply that artifacts and tools are represented in the same way. In the study participants categorized a set of objects (denoted by words) once as tools and once as artifacts. Results show that reaction times (RTs) are faster in the artifact categorization condition than in the tool categorization condition. This pattern indicates that artifacts and tools are not represented in the same way and that the identification of the members of each class is carried out in the basis of different criteria.

Autism often co-occurs with alexithymia, a condition characterized by no or diminished awareness of emotions that significantly impacts an individual's social relationships. We investigate how the social motivation of autistics would be eroded by comorbidity with alexithymia and why this diminished motivation would be difficult for non-autistic people to perceive and reciprocate.
