statement of the problem when root perforation occurs in the middle third of the root, considerable canal length that would normally be available for post placement must be filled by the repair material, which necessitates placement of a considerably shorter post, leading to poor retention. purpose the aim of this study was to compare retention of titanium parapost luted with mta and four diffe...

Objective. To study the effect of immunomodulators on learning and memory and on cholinergic receptor sensitivity. Methods. Animals were initially treated for a period of 8 days with cyclosporine/levamisole/saline. They were then subjected to passive avoidance training and 48 hrs later, the retention test for the passive avoidance task was conducted. Twenty-four hours after the retention tests ...

The test scheduling problem for built-in self-tested embedded SRAMs (e-SRAMs) when data retention faults (DRFs) are considered is addressed here. We proposed a ‘retention-aware’ test power model by taking advantage of the fact that there is near-zero test power during the pause time for testing DRFs. The proposed test scheduling algorithm then utilises this new test power model to minimise the ...

We recently reported that collaborative testing (i.e., group test taking) increased student performance on quizzes. It is unknown, however, whether collaborative testing improves student retention of course content. Therefore, this study was designed to test the hypotheses that collaborative-group testing improves student retention of course content. To test this hypothesis, our undergraduate e...

Although the benefits of spaced retrieval for long-term retention are well established, the majority of this work has involved spacing over relatively short intervals (on the order of seconds or minutes). In the present experiments, we evaluated the effectiveness of spaced retrieval across relatively short intervals (within a single session), as compared to longer intervals (between sessions sp...

The authors investigated the retention of implicit sequence learning in 14 persons with Parkinson's disease (PPD), 14 persons who stutter (PWS), and 14 control participants. Participants completed a nonsense syllable serial reaction time task in a 120-min session. Participants named aloud 4 syllables in response to 4 visual stimuli. The syllables formed a repeating 8-item sequence not made know...

this study was an attempt to investigate whether teaching critical reading strategies had any significant effect on intermediate efl learners’ vocabulary retention. to fulfill the purpose of this study, 72 male and female students within the age range of 17 to 32 years studying at farzan and farzanegan language schools in tehran at intermediate level were selected from a total number of 114 par...

this study aimed at examining the effect of different focus of attention instructions and cognitive styles on the learning of dart throwing skill. 80 children were randomly selected and divided into four equal groups: a) field independent-external attention, b) field independent-internal attention, c) field dependent-external attention and d) field independent-internal attention based on their ...

Two experiments examined the testing effect with open-book tests, in which students view notes and textbooks while taking the test, and closed-book tests, in which students take the test without viewing notes or textbooks. Subjects studied prose passages and then restudied or took an openor closed-book test. Taking either kind of test, with feedback, enhanced long-term retention relative to con...
