Developmental studies have provided mixed evidence with regard to the question of whether children consider sample size and sample diversity in their inductive generalizations. Results from four experiments with 105 undergraduates, 105 school-age children (M=7.2 years), and 105 preschoolers (M=4.9 years) showed that preschoolers made a higher rate of… (More)
Three experiments with 81 3-year-olds (M=3.62years) examined the conditions that enable young children to use the sample size principle (SSP) of induction-the inductive rule that facilitates generalizations from large rather than small samples of evidence. In Experiment 1, children exhibited the SSP when exemplars were presented sequentially but not when… (More)
A series of 2(Z)-2-benzylidene-6,7-dihydroxybenzofuran-3[2H]-ones was identified as potent inhibitors of bacterial chorismate synthase. The 2'-hydroxy-4'-pentoxy analogue 33 is a potent inhibitor of Streptococcus pneumoniae chorismate synthase.
The ability to determine that diverse samples provide better evidence for generalization than non-diverse samples is an important inductive skill. Adults tend to utilize the diversity principle of induction (DP), but evidence regarding children's ability to do so is mixed. The two experiments reported here examined whether the method by which evidence is… (More)
In two experiments with adults (N = 126), we examined the influence of sampling procedure on inductive generalization. In predicate sampling, participants learned the category identity of individuals known to possess some property. In subject sampling, individuals selected for category identity were discovered to possess a novel property. In both… (More)
Recent evidence suggests that infants can generate expectations about future events from a sample of probabilistic data. However, little is known about the conditions that support the development of this ability. Three experiments tested the prediction that 8- and 12-month-olds respond to base rates as well as perceptual cues when they generate expectations… (More)
A considerable amount of work has focused on the processes that underlie children's inductive reasoning. For instance, numerous studies explored the role of linguistic labels, perceptual similarity, and children's beliefs in generalization of properties to novel cases. The present studies investigated an aspect of induction that has received considerably… (More)
