Hyperreflective Dots in Central Fovea Visualized by a Novel Application of Visible-Light Optical Coherence Tomography.

Visible-light optical coherence tomography (vis-OCT) is a novel noninvasive retinal imaging system that offers improved resolution compared to conventional near-infrared (NIR) OCT systems. Here, we utilized vis-OCT to produce fibergrams (vis-OCTF) for the first time in human patients, enabling visualization and precise quantification of hyperreflective dots in the central fovea in two patients. We also directly compare the imaging qualities of conventional vis-OCT and NIR-OCT.

Montessori education's impact on academic and nonacademic outcomes: A systematic review.

Background: Montessori education is the oldest and most widely implemented alternative education in the world, yet its effectiveness has not been clearly established.

Objectives: The primary objective of this review was to examine the effectiveness of Montessori education in improving academic and nonacademic outcomes compared to traditional education. The secondary objectives were to determine the degree to which grade level, Montessori setting (public Montessori vs.

Family processes and structure: Longitudinal influences on adolescent disruptive and internalizing behaviors.

Objective: The present study revisits the assumption in American culture, based in "family privilege," that children fare better in two-parent households by longitudinally examining associations between family structure, process, and adolescent behavior.

Background: Societal assumptions and cross-sectional research suggest that there is a difference in child adjustment across varying family structures. Relatedly, the family process literature emphasizes the importance of parent-child relationship quality in addition to family structure on child adjustment.

Quantity and structure of word knowledge across adulthood.

Cross-sectional and longitudinal data from moderately large samples of healthy adults confirmed prior findings of age-related declines in measures of the quantity of word knowledge beginning around age 65. Additional analyses were carried out to investigate the interrelations of different types of vocabulary knowledge at various periods in adulthood. Although the organizational structures were similar in adults of different ages, scores on tests with different formats had weaker relations to a higher-order vocabulary construct beginning when adults were in their 60's.

Relations between Running Memory and Fluid Intelligence.

A total of 1,734 adults performed two running memory tasks and a battery of cognitive tests representing four cognitive abilities. Simultaneous analyses were used to identify unique relations of each cognitive ability, including fluid intelligence, on the running memory measures. The large sample size allowed powerful analyses of the relations at the level of individual trials, separate list lengths, and different serial positions.

Watch and Learn? Infants Privilege Efficiency Over Pedagogy During Imitative Learning.

This experiment tested how 18-month-old infants' prior experience with an object affects their imitation. Specifically, we asked whether infants would imitate an adult who used her head to illuminate a light-box if they had earlier discovered that the light could be illuminated with their hands. In the Self-Discovery condition, infants had the opportunity to freely explore the light-box; all infants used their hands to activate the light-box at least once during this period.

Infants' Response to Pictures of Impossible Objects.

Previous work has shown that 4-month-olds can discriminate between two-dimensional (2D) depictions of structurally possible and impossible objects [S. M. Shuwairi (2009), Journal of Experimental Child Psychology, 104, 115; S.

AFFECTIVE GUIDANCE OF INTELLIGENT AGENTS: How Emotion Controls Cognition.

Emotions and moods color cognition. In this article, we outline how emotions affect judgments and cognitive performance of human agents. We argue that affective influences are due, not to the affective reactions themselves, but to the information they carry about value, a potentially useful finding for creators of artificial agents.

The Effect of Vocabulary Size on Toddlers' Receptiveness to Unexpected Testimony About Category Membership.

Children must be willing to accept some of what they hear "on faith," even when that testimony conflicts with their own expectations. The study reported here investigated the relation among vocabulary size, object recognition, and 24-month-olds' (N = 40) willingness to accept potentially surprising testimony about the category to which an object belongs. Results showed that children with larger vocabularies were better able to recognize atypical exemplars of familiar categories than children with smaller vocabularies.
