introduction: alzheimer’s disease (ad) is a enfeeble neurodegenerative disorder characterized by increased β-amyloid (aβ) deposition and neuronal dysfunction leading to impaired learning and recall. among proposed risk factors, impaired cholinergic transmission is a main cause for incidence of disease. methods: in the present study, effects of the intracerebroventricularly administration of an ...

One important issue that any material or test designer should bear in mind is to be careful about developing teaching and testing reading materials which would not be to the benefit of a group of readers or examinees and to the detriment of some others. One of the factors which may cause difference between the performances of English learners or test takers is the selection of reading tests wit...

Experiments were carried out to determine if variations in adult native speaker performance arise from variations in working memory capacity (Just & Carpenter, 1992) or variations in procedural grammatical competence (Ericsson & Kintsch, 1995). Three groups of 18-year-old native speakers of English were tested on comprehension and recall of English Complex NP constructions. Two groups were ‘low...

Three experiments were conducted to investigate whether increasing the number of lures on a multiple-choice test helps, hinders or has no effect on later memory. All three patterns have been reported in the literature. In Experiment 1, the stimuli were unrelated word lists, and increasing the number of lures on an initial multiple-choice test led to better performance on later free recall and c...

On each of five study-test trials, young and old adults attempted to memorize the same list of 60 words (e.g., bed, rest, awake), which were blocked according to their convergence on four corresponding associates. Half of the participants in each age group were given an explicit warning about the DRM paradigm prior to encoding and were asked to attempt to avoid recalling any associated but nonp...

This research assesses the effects of a psychology of forgiveness pilot study on anger-recall stress induced changes in myocardial perfusion, forgiveness and related variables. Thirty-two patients were administered baseline rest and anger-recall stress imaging studies, and 17 of these participants who demonstrated anger-recall stress induced myocardial perfusion defects (forgiveness group, n = ...

In three experiments, participants studied photographs of common household scenes. Following study, participants completed a category-cued recall test without feedback (Exps. 1 and 3), a category-cued recall test with feedback (Exp. 2), or a filler task (no-test condition). Participants then viewed recall tests from fictitious previous participants that contained erroneous items presented eithe...
