Undergraduates studied nonword exemplars and then created their own novel nonwords. In Experiment 1, people studied legal or illegal nonwords. In Experiment 2, people studied illegal nonwords, but to increase awareness of the features, half of the participants assessed the features of the nonwords. Despite instructions to avoid copying any aspect…

Acquired aphasics and dyslexics with even very profound word reading impairments have been shown to perform relatively well on the lexical decision task (e.g., Buchanan, Hildebrandt, & MacKinnon, 1999), but direct contrasts with unimpaired participant's data is often complicated by extremely long reaction times for patient data. The dissociation…

Two experiments tested the common assumption that knowing the letter names helps children learn basic letter-sound (grapheme-phoneme) relation because most names contain the relevant sounds. In Experiment 1 (n=45), children in an experimental group learned English letter names for letter-like symbols. Some of these names contained the…

The present study provides evidence that individuals who have different patterns of cerebral lateralization and who develop along different maturational time courses can attain comparable levels of language proficiency. Right-handed individuals with left-handed family members (left-handed familials, LHFs) showed a shorter sensitive period for…

In this study, the authors examined the effect of retirement on psychological and physical symptoms in 404 older male veterans who were taking part in an ongoing longitudinal study. Hierarchical linear modeling was used to analyze symptom trajectories from preretirement, peri-retirement, and postretirement periods in veterans with either lifetime…

Long-term synaptic enhancement in the hippocampus has been suggested to cause deficits in spatial performance. Synaptic enhancement has been reported after hippocampal kindling that induced repeated electrographic seizures or afterdischarges (ADs) and after long-term potentiation (LTP) defined as synaptic enhancement without ADs. We studied…

The objective of the current study was to assess the effects of mandatory child abuse training on the knowledge, skills, and attitudes toward abused children and abusive parents among a sample of police recruits. An experimental pretest-posttest design was used in which 81 participants were randomly assigned to experimental conditions and 101 to…

The purpose of this study was to explore the effects of conceptual change texts oriented instruction on 9th grade students' understanding of chemical bonding concepts. In this study, the main aim of the preparation of conceptual change texts was to activate students' prior knowledge and misconceptions and to help them to understand the chemical…

Introduction: Many of the residents who supervise medical students in clinical practice are unfamiliar with the principles of effective supervision. Training in teaching skills is therefore seen as an effective strategy to improve the quality of clinical supervision. Method: Twenty seven medical residents were matched and assigned to an…

This paper explores the idea of informal science education in scientific field laboratory (The Science Field Centre). The experimental group of pupils (N = 153) was experienced with approximately 5-day lasting field trips and experiments in the Field Centre in Slovakia. After finishing the course, two different research methods were used to…

In this study, the research problem was: "Is the computer based physics instruction as effective as laboratory intensive physics instruction with regards to academic success on electric circuits 9th grade students?" For this research of experimental quality the design of pre-test and post-test are applied with an experiment and a control…

Web-based financial commentary, in which experts routinely express market-related thought processes, is proposed as a means for college students to learn vicariously about financial markets. Undergraduate business school students from a regional university were exposed to expert market commentary from a single financial Web site for a 6-week…

This study evaluated the efficacy of a preschool mathematics program based on a comprehensive model of developing research-based software and print curricula. Building Blocks, funded by the National Science Foundation, is a curriculum development project focused on creating research-based, technology-enhanced mathematics materials for pre-K…

This paper presents results of Year 2 of an Early Reading First project in a low-income, primarily African American community. Goals of Early Reading First include preparing at-risk preschoolers for school success. This project provided professional development, classroom coaching, books, and materials in support of a literacy-focused preschool…
