まとめ
読みながら逆行するサッカードは 明確なパターンを示します 単語の間の回帰は,発射距離によって影響を受け,普遍的な読み目の制御をサポートします.
科学分野:
- 認知心理学
- 神経科学
- 言語学
背景:
- 読み込み中の前方サッカード着陸位置はよく研究されています.
- 読み解くのに欠かせない 逆行的なサッカード行動は 理解されがちです
- 眼運動制御と空間記憶に関する洞察を 提供します
研究 の 目的:
- 読み取り中の回帰サッカードの着陸位置を調査する.
- 複数の言語で単語の内部と単語の間の回帰を区別する.
- 逆行サッカードと前向きのサッカードパターンを比較する.
主な方法:
- MECO L1プロジェクトからのアイトラッキングデータを使用した (589人の参加者,13言語).
- 正確な着陸位置を分析した 前進と後退のサッカード.
- 打ち上げ距離と言葉の特徴がサッカード着陸地点に与える影響を調べました.
主要な成果:
- 進んだサッカードは 打ち上げ距離の効果を示した. より長い距離は下射,より短い距離はオーバーショットにつながった.
- 発射距離や単語の長さに関係なく ターゲットワードの中心に一貫して着陸しました
- 発射距離によって影響を受ける着陸位置,特に発射の末端から発射する.
結論:
- リグレッシブサッカード精度は様々な言語に異常に一致しており,普遍的な眼運動制御メカニズムを示唆しています.
- 発見は空間的コード化仮説を支持し,空間的記憶が読書中の回帰的な眼の動きを導くことを示しています.
- 単語の内部と単語の間の回帰を区別すると,目の動きを読み取る際の微妙な制御戦略が明らかになります.

Uncertainty in Measurement: Reading Instruments
37.6K
Counting is the type of measurement that is free from uncertainty, provided the number of objects being counted does not change during the process. Such measurements result in exact numbers. By counting the eggs in a carton, for instance, one can determine exactly how many eggs are there in the carton. Similarly, the numbers of defined quantities are also exact. For example, 1 foot is exactly 12 inches, 1 inch is exactly 2.54 centimeters, and 1 gram is exactly 0.001 kilograms. Quantities...

Ratio Level of Measurement
13.7K
The way a set of data is measured is called its level of measurement. Correct statistical procedures depend on a researcher being familiar with levels of measurement. For analysis, data are classified into four levels of measurement—nominal, ordinal, interval, and ratio.
A set of data measured using the ratio scale takes care of the ratio problem and provides complete information. Ratio scale data are like interval scale data, except they have a zero point and ratios can be calculated....

Harmonic Mean
5.2K
The arithmetic mean is usually skewed towards the larger values in the data set. Therefore, to avoid this inherent bias towards smaller values, the harmonic mean is used.
Take the example of the speed of a car, which is the measure of the rate of distance traveled. If the vehicle traverses the same distance back-and-forth, its average speed equals the total distance traveled divided by the total time taken. However, if the car moves with varying speeds, then the arithmetic mean is more skewed...

Trimmed Mean
2.2K
While measuring the mean of a data set, care needs to be taken when associating the mean to its central tendency. The same goes for the arithmetic mean, the geometric mean, or the harmonic mean. This is because the presence of a single outlier data value can significantly affect the mean. That is, the mean is sensitive to fluctuations in the data set.
Although certain measures of central tendency are not sensitive to outliers, there are alternative versions of the mean that get around the...

Percentile
6.4K
A percentile indicates the relative standing of a data value when data are sorted into numerical order from smallest to largest. It represents the percentages of data values that are less than or equal to the pth percentile. For example, 15% of data values are less than or equal to the 15th percentile. Low percentiles always correspond to lower data values. High percentiles always correspond to higher data values.Percentiles divide ordered data into hundredths. To score in the...

Learning Disabilities

Learning disabilities are cognitive disorders caused by neurological impairments that affect cognitive functions like language and reading, without indicating overall intellectual or developmental challenges. These disabilities differ from global intellectual or developmental disabilities as they are limited to distinct cognitive functions. Common learning disabilities include dysgraphia, dyslexia, and dyscalculia, each of which impacts unique aspects of learning.
