Young children's use of features to reorient is more than just associative: further evidence against a modular view of spatial processing.

Proponents of a geometric module have argued that instances of young children's use of features as well as geometry to reorient can be explained by a two-stage process. In this model, only the first stage is a true reorientation, accomplished by using geometric information alone; features are considered in a second stage using association (Lee, Shusterman & Spelke, 2006). This account is contradicted by the data from two experiments.

Infants prefer motionese to adult-directed action.

In two studies, we investigated infants' preference for infant-directed (ID) action or 'motionese' (Brand, Baldwin & Ashburn, 2002) relative to adult-directed (AD) action. In Study 1, full-featured videos were shown to 32 6- to 8-month-olds, who demonstrated a strong preference for ID action. In Study 2, infants at 6-8 months (n= 28) and 11-13 months (n= 24) were shown either standard ID and AD clips, or clips in which demonstrators' faces were blurred to obscure emotional and eye-gaze information.

Social working memory: Memory for another rat's spatial choices can increase or decrease choice tendencies.

In two experiments using a radial-arm maze, pairs of rats made choices among eight maze locations, each containing a large quantity of one of two food types. The choices made by 1 rat affected the choices made by the other rat. Under most conditions, visits by 1 rat increased the tendency of the other rat to subsequently choose that maze location.
