To investigate the most efficient way to represent text in reading Chinese on computer displays, three typographic variables, character size (41[feet] arc/24 pixels and 60[feet] arc/32 pixels), character spacing (1/4 and 1/8 character width) and font type (Kai and Ming), were manipulated. Results showed that the reading speed for Chinese characters of Kai type in 24 pixels with 1/8 character spacing was the shortest. Character size significantly affected overall reading speed; in specific, text in 24-pixel characters was read faster than text in 32-pixel characters. Further eye-movement analyses revealed that text in smaller-sized characters had longer fixation duration, fewer fixations and fewer regressions than text in larger-sized characters. The interaction between character spacing and font type was observed on overall reading efficiency and on some eye-movement measures, which suggests that different character spacings should be considered in different font types for more efficient reading. Generally, characters in Kai font were easier to read with 1/8 character spacing than with 1/4 character spacing. The relationship between eye-movement measures and overall reading efficiency was further discussed. (Contains 7 figures and 1 table.)

Hindsight bias (HB) is the tendency to retrospectively exaggerate one's foresight knowledge about the outcome of an event. Cognitive processes influenced by newly obtained outcome information are used to explain the HB phenomenon, but the neural correlates remain unknown. This study investigated HB in the context of election results using a memory design and functional magnetic resonance imaging for the first time. Participants were asked to predict and recall the percentage of votes obtained by (pairs of) candidates before and after an election. The results revealed that 88% of participants showed HB by recalling that their predictions were closer to the actual outcomes than they really were; and participants had HB for 38% of the events. The HB effect was associated with activation in the medial superior frontal gyrus and bilateral inferior frontal gyrus (IFG), which have been implicated in updating an old belief due to new information and is similar to the process of reconstruction bias. Furthermore, participants with a greater HB effect showed greater activation of the left IFG. In conclusion, we successfully observed the HB phenomenon in election results, and our imaging results suggested that the HB phenomenon might involve reconstruction bias. [ABSTRACT FROM AUTHOR]

To investigate the most efficient way to represent text in reading Chinese on computer displays, three typographic variables, character size (41′ arc/24 pixels and 60′ arc/32 pixels), character spacing (1/4 and 1/8 character width) and font type (Kai and Ming), were manipulated. Results showed that the reading speed for Chinese characters of Kai type in 24 pixels with 1/8 character spacing was the shortest. Character size significantly affected overall reading speed; in specific, text in 24-pixel characters was read faster than text in 32-pixel characters.

The role of phonological coding for character identification was examined with the benefit of processing parafoveal characters in eye fixations while reading Chinese sentences. In Experiment 1, the orthogonal manipulation of phonological and orthographic similarity can separate two types of phonological benefits for homophonic previews, according to whether these previews share the same phonetic radical with the targets or not. The significant phonological benefits indicate that phonological coding is activated early when the character is in the parafovea. Experiment 2 manipulated the character's consistency value and found that the phonological preview benefits are reliable only when the targets are high consistency characters. The results of two experiments suggest that phonological computation is rapid and early at both character and radical levels for Chinese character identification.
