The terrestrial slug "Limax" is able to acquire short-term and long-term memories during aversive odor-taste associative learning. We investigated the effect of the selective serotonergic neurotoxin 5,7-dihydroxytryptamine (5,7-DHT) on memory. Behavioral studies indicated that 5,7-DHT impaired short-term memory but not long-term memory. HPLC…

The purpose of this study was to assess the nonword repetition skills of 24 children who do (CWS; n=12) and do not stutter (CWNS; n=12) between the ages of 3;0 and 5;2. Findings revealed that CWS produced significantly fewer correct two- and three-syllable nonword repetitions and made significantly more phoneme errors on three-syllable nonwords…

This paper explored and described the analogical reasoning occurring in the minds of different science achievement groups for the concept of translation in protein synthesis. "What is the process of self-generated analogical reasoning?", "What types of matching was involved?" and "What are the consequences of the matching…

The nature of predictive relations between early language and later cognitive function is a fundamental question in research on human cognition. In a longitudinal study assessing speed of language processing in infancy, Fernald, Perfors and Marchman (2006 ) found that reaction time at 25 months was strongly related to lexical and grammatical…

In this paper, we present data from an evaluation of the educational impact of a school breakfast program implemented in rural schools in Peru. The results showed positive effects on school attendance and dropout rates, and a differential effect of the breakfast program on multiple-grade and full-grade schools. Particularly in multiple-grade…

Purpose: This study investigated the effects of processing speed and phonological short-term memory (PSTM) on children's language performance. Method: Forty-eight school-age children with specific language impairment (SLI) and age peers completed auditory detection reaction time (RT) and nonword repetition tasks, the Clinical Evaluation of…

We tested whether memory deficits in temporal lobe epilepsy (TLE) are better described by a single- or dual-store memory model. To this aim, we analyzed the influence of TLE and proactive interference (PI) on immediate and 24-h long-term recency effects during face recognition in 16 healthy participants and 18 right and 21 left non-surgical TLE…

The aim of this study was to compare the compositional performances of deaf and hearing students and to investigate the relationships between these performances and working memory capacities. Fifteen prelingually deaf, sign-using students and 15 hearing students composed a descriptive text and performed working memory tasks. The deaf students had…

In three experiments, we tested the hypothesis that those errors in immediate serial recall (ISR) that are attributable to phonological confusability share a locus with segmental errors in normal speech production. In the first two experiments, speech errors were elicited in the repeated paced reading of six-letter lists. The errors mirrored the…

The prefrontal cortex of the primate frontal lobes provides the capacity for judgment which can constantly adapt behavior in order to optimize its outcome. Adjudicating between long-term memory programs and prepotent responses, this capacity reviews all incoming information and provides an interpretation dependent on the events that have just…

Groups of Grade 3 children were tested on measures of word-level literacy and undertook tasks that required the ability to associate sounds with letter sequences and that involved visual, auditory and phonological-processing skills. These groups came from different language backgrounds in which the language of instruction was Arabic, Chinese,…

The authors examined second grade reading accuracy and fluency and their associations via letter knowledge to phonological and language predictors assessed at 3.5, 4.5, and 5.5 years in children in the Jyvaskyla Longitudinal Study of Dyslexia. Structural equation modeling showed that a developmentally highly stable factor (early phonological and…

This paper discusses brain-based learning and its relation to classroom instruction. A rapidly growing quantity of research currently exists regarding how the brain perceives, processes, and ultimately learns new information. In order to maximize their teaching efficacy, educators should have a basic understanding of key memory functions in the…

A study examined three variables derived from earlier research on comprehension and recall of narrative text: time in short-term memory; causal connections allowed; and referential connections allowed. Subjects, 84 randomly selected fourth graders in three suburban public elementary schools, read 8 short texts that each contained 4 embedded goals,…

Recent theories in cognitive psychology have emphasized the role of capacity requirements in encoding tasks. To examine the notion that age-related differences in the recall performance reflect differences in cognitive capacity, 80 adults (40 undergraduates, and 40 senior citizens) recalled newspaper advertisements under free recall and cued…
