    Results from Study 1: group size.

    No full text
    <p>Note that there was no effect of group size on a take-the-best (TTB) group's performance in this set of simulations, because the group was assumed to be totally homogeneous. MIN-1, MIN-5, MIN-15, and MIN-100 stand for a minimalist group with 1, 5, 15, and 100 agents, respectively. Environments differed in their distribution of cue validities: LD, large difference; MD, medium difference; SD, small difference; ND, no difference. PC: Percentage correct.</p

    Results from Study 3: information errors.

    No full text
    <p>Because the results in the MD and ND environments were similar to the results in the LD and SD environments, respectively, only results from the LD and SD environments are shown for the sake of brevity. Group size was 5 for all groups from which the results were derived, and the magnitude of error was measured as the standard deviation of a normal distribution from which the random errors were generated. MIN-Group and MIN-Ind.: Minimalist group and individual agents. TTB-Group and TTB-Ind.: Take-the-best group and individual agents.</p

    Results from Study 2: individual learning.

    No full text
    <p>Because the results in the MD and ND environments were similar to the results in the LD and SD environments, respectively, only results from the LD and SD environments are shown for the sake of brevity. Group size was 5 for all groups from which the results were derived, and the amount of learning was measured by the number of options in a learning sample. The lines for minimalist agents and groups are flat because no learning was assumed to take place for a minimalist agent in this set of simulations. Pop: Population. MIN-Group and MIN-Ind.: Minimalist group and individual agents. TTB-Group and TTB-Ind.: Take-the-best group and individual agents.</p
