Learning produced by escape and spontaneous alternation

Spontaneous Alternation Behavior in Human Neutrophils

‏‎a comparative study of language learning strategies employmed by bilinguals and monolinguals with reference to attitudes and motivation‎‏

هدف از این تحقیق بررسی برخی عوامل ادراکی واحساسی یعنی استفاده از شیوه های یادگیری زبان ، انگیزه ها ونگرش نسبت به زبان انگلیسی در رابطه با زمینه زبانی زبان آموزان می باشد. هدف بررسی این نکته بود که آیا اختلافی چشمگیر میان زبان آموزان دو زبانه و تک زبانه در میزان استفاده از شیوه های یادگیری زبان ، انگیزه ها نگرش و سطح مهارت زبانی وجود دارد. همچنین سعی شد تا بهترین و موثرترین عوامل پیش بینی کننده ...

Modulation of hippocampal acetylcholine release and spontaneous alternation scores by intrahippocampal glucose injections.

Recent evidence indicates that systemic glucose treatment enhances memory while producing a corresponding increase in hippocampal acetylcholine (ACh) output. The present experiments examined whether unilateral intrahippocampal infusions of glucose would enhance spontaneous alternation performance and whether there would be a corresponding increase in ACh output in the ipsilateral and contralate...

Spontaneous alternation in marine crabs: invasive versus native species.

Organisms ranging from paramecia to humans tend to explore places that have been least recently explored, which is referred to as spontaneous alternation. Although organisms rely on different sources of information in alternating between places, the emergent behavioral pattern is likely advantageous during exploration and foraging. Under this rationale, continuous spontaneous alternation perfor...

The Learning Effect Produced by Expert Tutoring

The extraordinary improvement in learning achieved by replacing classroom instruction with one (or a few)-on-one tutoring by an expert tutor for an entire course is well known (the 2 sigma effect; Bloom, Educational Res 13: 4, 1984). However, most tutoring involves brief, infrequent sessions between a student and a tutor. The impacts of such interactions have not been well studied. We (Rovick &...
