Reaction to spatial novelty and exploratory strategies in baboons

Exploratory activity was examined in 4 young baboons with the aim of investigating the type of spatial coding (purely geometric and/or by taking into account the identity of the object) used for the configuration of objects. Animals were individually tested in an outdoor enclosure for their exploratory reactions (contact time and order of spontaneous visits) to changes brought about to a configuration of different objects. Two kinds of spatial changes were made: a modification (1) of the shape of the configuration (by displacement of one object) and (2) of the spatial arrangement without changing the initial shape (exchanging the location of two objects). In the second experiment, the effect of a spatial modification of the global geometry constituted by four identical objects was investigated. Finally, in the third experiment, a substitution of a familiar object with a novel one was performed without changing the objects’ configuration. The baboons strongly reacted to geometrical modifications of the configuration. In contrast, they were less sensitive to modifications of local features that did not affect the initial spatial configuration. Analyses of spontaneous exploratory activities revealed two types of exploratory strategies (cyclic and back-and-forth). These data are discussed in relation to (1) the distinction between the encoding of geometric versus local spatial features and (2) the spatial function of exploratory activity.     

Cultural conceptions of morality: Examining laypeople’s associations of moral character

Whether moral conceptions are universal or culture-specific is controversial in moral psychology. One option is to refrain from imposing theoretical constraints and to ask laypeople from different cultures how they conceptualize morality. Our article adopts this approach by examining laypeople’s associations of moral character in individualistic- and collectivistic-oriented cultures. Using correspondence analysis we found that the concept of moral character yielded widely shared associations with justice and welfare concerns. Yet, there were also clear cultural differences with individualistic-oriented samples associating more frequently rights-based features and collectivistic-oriented samples more frequently associating duty-based attributes. When matching freelisted trait categories with Schwartz’s value types, moral value hierarchies were similar across cultures and correlated significantly with explicit moral value ratings. We conclude that imposing constraints through an expert-designed category system can narrow the scope of inquiry to common moral aspects related to problem-solving, promotion of prosocial actions and control of antisocial behaviour.
