Reading span in Russian Elaborated by Olga Fedorova and colleagues in 2001 Processing: reading Reading span in Russian Elaborated by Olga Fedorova and colleagues in 2001 Processing: reading sentences Storage: maintaining the final words of these sentences 70 sentences, 12 -15 words each NB! Russian sentences appear to be much longer if we count the number of syllables, since the portion of one or two syllable words in Russian is significantly less than in English Visual or auditory presentation

Данный эксперимент тестирует объем Вашей оперативной памяти; информация в ней хранится всего несколько секунд. Данный эксперимент тестирует объем Вашей оперативной памяти; информация в ней хранится всего несколько секунд. Вам необходимо будет запоминать и потом воспроизводить последние слова предложений, которые Вы будете слышать, точно в той же форме и в том же порядке, в которой они были произнесены. This is the test of your working memory. The working memory stores information for just a few seconds. You will be listening to sentences, and you will have to memorize the final words of these sentences. Then you will have to recall these words keeping their form and the order of appearance.

Количество предложений будет неуклонно возрастать, тем самым Ваше задание будет усложняться. Если Вы не Количество предложений будет неуклонно возрастать, тем самым Ваше задание будет усложняться. Если Вы не можете вспомнить последнее слово какого-то предложения, переходите к следующему. The number of the sentences in a series will be increased step by step, so the difficulty of the task will grow. If you cannot recall some word, please, skip it and go on to the next one.

Study I: semantically related final words Experimental condition И мне стало грустно, когда я Study I: semantically related final words Experimental condition И мне стало грустно, когда я подумал, что они не пойдут завтракать в шикарный ресторан. Содрав с маленьких сухощавых рук перчатки, Нина последний раз в жизни ела моллюски. Увидев маленькое кафе, он юркнул туда, чтобы передохнуть, и заказал еще одну чашку кофе. Вино выдерживали слишком долго, и оно совсем испортилось и потеряло свой цвет и вкус.

Nina teared off her gloves from her small lean hands and for the last time in her life was eating shellfish. When he got a sight of a small café, he dropped in to have some rest and ordered another cup of coffee. The vine was aged for too long, so it finally was spoilt and has lost its color and taste.

Надо было достойно вознаградить усилия того, кто достиг совершенства в своем ремесле. Он сидел на скамье и показался мне темной, бесформенной грудой в образе человека. Граф закрыл окно и задернул шторы: сквозняк и электрический свет привлекают молнию.

An appropriate reward was needed for the effort of one who reached perfection in his profession. He was sitting on the bench and seemed to me as a dark shapeless pile in appearance of a human. The earl closed the window and drew the draperies since the draught and the electric light attract the lighting.

Working memory span correlates with text comprehension EXAMPLE: Comprehension of the text with large Working memory span correlates with text comprehension EXAMPLE: Comprehension of the text with large reference distances in people with high and low ‘reading span’ Daneman, M. , & Carpenter, P.

Reference distance 2 Reference distance 6 It was midnight and the jungle was very Reference distance 2 Reference distance 6 It was midnight and the jungle was very still. Suddenly the cry of a wolf pierced the air. This anguished note was followed by a flurry of activity. All the beasts of the jungle recognized that an urgent meeting had been summoned by the lion, their king. Representatives from each species made rapid preparations to get to the river clearing. This was where all such emergency assemblies were held. The elephant and tiger were the first to arrive. Next came the gorilla, panther and snake. They were followed by the owl and the crocodile. The proceedings were delayed because the leopard had not shown up yet. There was much speculation as to the reasons for the midnight alarm. Finally he arrived and the meeting could commence. Sitting with Richie, Archie, Walter and the rest of my gang in the Grill yesterday, I began to feel uneasy. Robbie had put a dime in the juke box. It was blaring one of the latest "Rock and Roll" favorites. I was studying, in horror, the reactions of my friends to the music. I was especially perturbed by the expression on my best friend's face. Wayne looked intense and was pounding the table furiously to the beat. Now, I like most of the things other teenage boys like. I like girls with soft blonde hair, girls with dark curly hair, in fact all girls. I like milkshakes, football games and beach parties. I like denim jeans, fancy T-shirts and sneakers. It is not that I dislike rock music but I think it is supposed to be fun and not taken too seriously. And here he was, "all shook up" and serious over the crazy music. Question: Who finally arrived? Question: Who was "all shook up" and serious over the music?

Why is the correlation? ü There is no correlation of linguistic skills with standard Why is the correlation? ü There is no correlation of linguistic skills with standard single task working memory test like word or digit span (Turner&Engle, 1989). ü The correlation is there even if we substitute the sentences by arithmetic expressions and/or final words by final figures (Turner&Engle, 1989). ü Modifications of the processing task (i. e. different types of judgements about the sentence) give correlations at the range 0. 52 -0. 63 (Waters & Caplan, 1996) ü Test-retest reliability is only moderate: correlations at the range 0, 41 -0, 54 (Kuntsi et al. , 2001)

Conclusions ü Russian version of the standard reading span test fits the classic model Conclusions ü Russian version of the standard reading span test fits the classic model of the working memory structure proposed by Alan Baddeley ü The test apparently provides a measure of individual verbal processing abilities rather than individual working memory capacity as such
