Episodic memory depends upon multiple dissociable retrieval processes. Here we investigated the degree to which the processes engaged during successful retrieval are dependent on the properties of the representations that underlie memory for an event. Specifically we examined whether the individual elements of an event can, under some conditions,…

The study investigated the dynamic relation between contingency learning and heart rate with risk and non-risk babies 5- to 10-months-old. Four groups were compared in a two contingency treatments (contingent, yoked) x two risk status design. Concurrent heart rate was monitored during three phases of a contingency learning task (baseline,…

The aim of this study was to explore the developmental links between conversational perspective-taking and false belief attribution. To examine this, 81 children aged between 3 and 4 years participated in a longitudinal study over a period of 1 year, with three measurement sessions being performed at 6-month intervals. The children were assessed…

The study investigated the effects of music with high arousal potential and negative affect (HA), music with low arousal potential and positive affect (LA), and everyday noise, on the cognitive task performance of introverts and extraverts. Forty participants completed five cognitive tasks: immediate recall, free recall, numerical and delayed…

The present study investigated the effects of acute stress exposure on learning performance in humans using analogs of two paradigms frequently used in animals. Healthy male participants were exposed to the cold pressor test (CPT) procedure, i.e., insertion of the dominant hand into ice water for 60 sec. Following the CPT or the control procedure,…

Participants report briefly-presented words more accurately when two copies are presented, one in the left visual field (LVF) and another in the right visual field (RVF), than when only a single copy is presented. This effect is known as the "redundant bilateral advantage" and has been interpreted as evidence for interhemispheric cooperation. We…

High-stakes writing assessments currently exert a strong influence on the writing curriculum and instruction in schools across the United States. Under these circumstances it is important to examine the construct of writing competence on which these assessments are based, as well as the extent to which this construct supports the goals of…

We conducted four experiments to examine developmental differences in preferences for using color, size, and location information to disambiguate hiding places. Three- and 4-year-olds and adults described how to find a miniature mouse that was hidden in one of two highly similar small objects in a dollhouse. In Experiment 1, the hiding places…

This study examined 6-month-old infants' abilities to use the visual information provided by simulated self-movement through the world, and movement of an object through the world, for spatial orientation. Infants were habituated to a visual display in which they saw a toy hidden, followed by either rotation of the point of observation through the…

SV sentences with unaccusative verbs like "The leaf fell" involve movement from object to subject position. This line of studies tested whether young children can produce this movement and whether they represent SV sentences with unaccusatives as derived by movement. In Hebrew, unaccusatives appear in both SV and VS orders. This optionality allows…

In a task choice situation, why do some students spontaneously choose challenging tasks while others do not? In the study, 114 undergraduate students were first asked of their perceived competence and interest in solving number puzzles at both individual and situational levels, and then asked to choose one puzzle from four difficulty levels. They…

One of the important phenomena observed in the learning of mathematics is compartmentalization. This phenomenon occurs when a learner has two different, potentially contradictory schemes in his or her cognitive structure; in a typical case, a student deals with the same mathematical concept in an inconsistent or incoherent way, or activates a less…

This study assessed relations among placement instability, inhibitory control, and caregiver-rated child behavior. The sample included 33 adopted children who had experienced placement instability, 42 adopted children who had experienced 1 stable placement, and 27 children never placed in foster care. Five- and 6-year-old children completed the…

Recent data suggest that subthreshold presentation of emotional information is relayed to the amygdala along subcortical pathways. We examined the effect of backward masked neutral and anxious faces on the social decisions of a group of high functioning children with autism ages 7-13 years and matched controls. Participants were asked to select…

An exploratory study was designed to describe Internet search behaviors of deaf adolescents who used Internet search engines to complete fact-based search tasks. The study examined search behaviors of deaf high school students such as query formation, query modification, Web site identification, and Web site selection. Consisting of two fact-based…
