The current meta-analysis synthesized findings from profiling research on Chinese children with reading difficulties (RD). We reviewed a total of 81 studies published between 1964 and May 2015, representing a total of 9735 Chinese children. There are 982 effect sizes for the comparison between children with RD and age-matched typically developing…

In Chinese orthography, a dominant character structure exists in which a semantic radical appears on the left and a phonetic radical on the right (SP characters); a minority opposite arrangement also exists (PS characters). As the number of phonetic radical types is much greater than semantic radical types, in SP characters the information is…

In this paper three experimental techniques are described for studying ambiguous characters and for investigating the relationship between physical attributes and functional attributes. (Author)

Research indicates that young children seem to have considerable difficulty in discrimination between the letters b, c, p, and q. Also, 4-year-olds appear to commonly make rotation and reversal errors with letter-like forms. Whether young children will perform significantly better or not in deciding whether two shapes are called same or different…

In order to understand the process of reading, it is important to determine how strings of letters are perceived. This study tests the hypothesis that units of visual perception may include pairs of letters and perhaps even high-frequency, monosyllabic trigrams (three-letter sequences). Participants were asked to report the names of either single…

The studies reported here examined the role of orthographic regularity and summed positional frequency in the perception of letter strings. College sophomores and sixth graders were asked to indicate whether or not a target letter was present in a six-letter string. Orthographic regularity and summed positional frequency were found to have no…

"32 English readers and 32 Hebrew readers were shown stimuli with directional characteristics (English and Hebrew letters) and stimuli with no directional characteristics (arrays of different circles, bars, colors, and geometric figures) for scanning. The results showed that, while directional stimulus characteristics affected the direction…
