  • A pointer's hypothesis of general intelligence evolved from domain-specific demands
    Behav. Brain. Sci. (IF 14.2) Pub Date : 2017-08-15
    X. T. (Xiao-Tian) Wang

    A higher-order function may evolve phylogenetically if it is demanded by multiple domain-specific modules. Task-specificity to solve a unique adaptive problem (e.g., foraging or mating) should be distinguished from function-specificity to deal with a common computational demand (e.g., numeracy, verbal communication) required by many tasks. A localized brain function is likely a result of such common computational demand.

  • When does cultural transmission favour or instead substitute for general intelligence?
    Behav. Brain. Sci. (IF 14.2) Pub Date : 2017-08-15
    Andrew Whiten

    The cultural intelligence hypothesis is an exciting new development. The hypothesis that it encourages general intelligence is intriguing, but it presents a paradox insofar as social learning is often suggested to instead reduce reliance on individual cognition and exploration. There is thus a need to specify more clearly the contexts in which cultural transmission may select for general intelligence.

  • General intelligence is a source of individual differences between species: Solving an anomaly
    Behav. Brain. Sci. (IF 14.2) Pub Date : 2017-08-15
    Michael A. Woodley of Menie, Heitor B. F. Fernandes, Jan te Nijenhuis, Mateo Peñaherrera-Aguirre, Aurelio José Figueredo

    Burkart et al. present a paradox – general factors of intelligence exist among individual differences (g) in performance in several species, and also at the aggregate level (G); however, there is ambiguous evidence for the existence of g when analyzing data using a mixed approach, that is, when comparing individuals of different species using the same cognitive ability battery. Here, we present an empirical solution to this paradox.

  • Future directions for studying the evolution of general intelligence
    Behav. Brain. Sci. (IF 14.2) Pub Date : 2017-08-15
    Judith M. Burkart, Michèle N. Schubiger, Carel P. van Schaik

    The goal of our target article was to lay out current evidence relevant to the question of whether general intelligence can be found in nonhuman animals in order to better understand its evolution in humans. The topic is a controversial one, as evident from the broad range of partly incompatible comments it has elicited. The main goal of our response is to translate these issues into testable empirical predictions, which together can provide the basis for a broad research agenda.
