Toddlers can reason by exclusion: they don’t search in a bucket they saw was empty./ 3- to 5-yos reason by exclusion by using the disjunctive syllogism./ In contrast, 2.5-yos appear to use a non-deductive approach./ Children under 3 may not be capable of making this logical inference.
Post-reproductive lifespans (PRLSs) of men vary across traditional societies. We argue that if sexual selection operates on male age-dependent resource availability (or ‘reproductive market values’), the result is variation in male late-life reproduction across subsistence systems
Social learning strategies (SLS). The author discusses possible research strategies to answer what processes are behind the selection of whom one learns from.
Hippocampus has two functions: memory consolidation and spatial navigation. Recently the third function, i.e., simulating future events is proposed but some point out evidence against the hypothesis. The paper examines it.
Bilingualism and multilingualism lead to advantages in executive functions. • Cognitive advantages are found even for speakers of two very similar varieties. • Multilingual and bilectal advantage is found across the executive control system.
Apes and infants point to an empty location to request more of its previous content..Requests depend on the quality of a visible alternative compared to the absent object. First evidence that apes and infants are specific in their requests of absent entities.
We examine the role of sortal concepts in how adults identify and individuate physical objects. • We find that sortals do not determine when an object is no longer identical to an earlier one. • We also find that sortals do not provide determinate conditions for individuating objects.
Degree of essentialist beliefs held by mental health professionals on mental disorder. Found: E-beliefs are reduced in professional but not necessarily correlated with expertise.
We tested whether infants would use the prior actions of an agent to help her attain her present goal. Infants attribute goals to agents, but these attributions do not guide their acts of helping. Helping actions, guided by goals, emerge between 14 and 24 months of age.
A disposition of analytic thinking is correlated to one's acceptance of evolutionary theory in a large number of N (>1000). The author talks about this in the DPT framework.
