BACKGROUND Ambient air pollution may have neurotoxic effects in children. Data examining associations between traffic-related air pollution and attention domains remain sparse. OBJECTIVES We examined associations between black carbon (BC), a marker of traffic particles, and attention measures ascertained at 7-14 years of age among 174 children in a birth cohort based in the Boston, Massachuse...

Young children learning Malayalam use morphological categories and inflections quite productively accurately in general. However, their utterances sometimes show the of extra material (or commission errors), revealing mismatches between adult child grammars. In this paper, we present a survey such errors that are observed longitudinally collected, spontaneous speech production data monolingual ...

A suspect of a crime can avoid legal repercussions by creating false alibi. We examined whether such alibi have adverse effects on memory. To do so, participants watched mock video and were either instructed to create or provide an honest account for what they actually saw in the video. After 2-day 1-month delay, all come forward with truth using free recall task. Participants who initially cre...

OBJECTIVE The aim of this study was to evaluate the association between a variable number of tandem repeats polymorphism at the dopamine D4 receptor gene (DRD4) and the performance of children with attention deficit hyperactivity disorder (ADHD) in a continuous performance test (CPT). METHODS This study included 72 ADHD children (mean age=9.39+/-2.05 years) who were recruited from one child p...

Errors trigger changes in behavior that help individuals adapt to new situations. The dorsal anterior cingulate cortex (dACC) is thought to be central to this response, but more lateral frontal regions are also activated by errors and may make distinct contributions. We investigated error processing by studying 2 distinct error types: commission and timing. Thirty-five subjects performed a vers...

This study tested the convergence of behavioral inhibition measures across emotional and non-emotional versions of the same go/no-go task in 85 college students. The two tasks differed only in the stimuli used for trial cues (i.e., circles versus facial expressions). Moderate correlations (r=.51-.56) between commission errors across the emotional and non-emotional tasks support the construct va...

Prospective memory research almost exclusively examines remembering to execute an intention, but the ability to forget completed intentions may be similarly important. We had younger and older adults perform a prospective memory task (press Q when you see corn or dancer) and then told them that the intention was completed. Participants later performed a lexical-decision task (Phase 2) in which ...

This paper discusses methods for the application of remote sensing in post earthquake damage assessment, and reports on a GEO-CAN crowd-sourcing study following the 22.2.2011 Christchurch event, and its validation using field studies. It describes the principal datasets used, discusses in detail the problems of validation, and considers the extent of omission and commission errors. It is clear ...
