Working memory means a lot in incidental vocabulary learning and retention. The present study examines the correlation between two types of working memory—complex phonological short-term memory—and from captioned videos. After conducting an empirical research to 125 young learners English as foreign language with tests: operation span test, which measured complex memory, non-word repetition mem...

Forgetfulness results in interference and/or deletion. Visual shortterm memory (VSTM) gradually decays as the retention time elapses, causing forgetfulness. Little is known about forgetfulness in VSTM, while substantial studies on VSTM have focused on the process of memory encoding, often with control of attention. Evidences suggest that the prefrontal cortex may contribute to maintain short-te...

introduction: lead (pb) is a neurotoxin that its different effects on the central nervous system are well-known. previous studies have reported the potent effects of vitamin c on memory.the present study was undertaken to evaluate the protective effects of vitamin c against leadinduced amnesia. methods: male wistar rats were divided into 4 groups: the control (saline), negative control (lead), ...

Objective(s): There is controversial evidence about the effect of methamphetamine (METH) on spatial memory. We tested the time- dependent effects of METH on spatial short-term (working) and long-term (reference) memory in METH –sensitized and withdrawn rats in the Morris water maze. Materials and Methods: Rats were sensitized to METH (2 mg/kg, daily/5 days, SC). Rats were trained in water maze ...

the present study aimed to examine throwing accuracy and spatial and digit working memory of field dependent-independent participants. the group embedded figure test (geft) was distributed among 320 male students and based on the geft scores, 45 participants were randomly divided into field dependent, field independent and control group (15 participants/each group). the study included two tasks...

Although work in a wide variety of species and paradigms has demonstrated that long-term memory is sensitive to the blocking of protein synthesis, previous studies have suggested that the honeybee might represent an exception to this rule. Retention tested one day after training was not impaired by the inhibition of translation by cycloheximide. Using blockers of either transcription (actinomyc...

Explicit measures of human memory, such as recall or recognition, reflect conscious recollection of the past. Implicit tests of retention measure transfer (or priming) from past experience on tasks that do not require conscious recollection of recent experiences for their performance. The article reviews research on the relation between explicit and implicit memory. The evidence points to subst...

Introduction: There is evidence indicating that the rate of AD is lower in curry consuming populations. Then, there is an effort to elucidate if curcumin -as the main ingredient of turmeric- might affect the process of AD. However, in clinical trials of AD, a six-month curcumin treatment failed to show any progress, which might be attributable to its low bioavailability. In this line, a recent ...

AbstractThis study aimed at examining the effect of pictorial presentation of vocabulary on EFL students’ retention relying on Dual Coding Theory and Additivity Hypothesis, both of which emphasize the additive effect of images on recall. To that end, 63 students who were in grade three of high school served as the participants of the study. They were randomly divided into three groups of still ...

Dopamine is necessary for the aversive olfactory associative memory formation in Drosophila, but its effect on other stages of memory is not known. Herein, we studied the effect of enhanced dopaminergic signaling on aversive olfactory memory retention in flies. We used l-3,4-dihydroxyphenylalanine (l-DOPA) to elevate dopamine levels: l-DOPA-treated flies exhibited a normal learning performance,...
