Subclaims¶
Reading the evidence codes
q is the design tier, i the impact, n the sample, and the kind with its r
the rigour judged within that kind: what each code means.
This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.
q3 i? L1 readers showed significant repetition effects earlier (from the first encounter in some measures) than L2 readers (third to fourth encounter), but there were no significant differences between L1 and L2 gains in reading times. → Pellicer-Sánchez 2016
q3 i? There was no significant difference between L1 and L2 participants in acquisition of form recognition, meaning recognition, or meaning recall. → Pellicer-Sánchez 2016

q3 · i? · causal · r2
Mann-Whitney tests comparing gain scores of 25 L1 and 23 L2 readers across the eight encounters; no significant differences in gains for targets or controls. The article states the only L1-L2 difference "was not in the magnitude of the observed effect but in its rate."
"Results showed that there were no significant differences between their gains, both for targets (gains first fixation duration: Z = –.59, p = .556; gains gaze duration: Z = –.96, p = .337; gains number of fixations: Z = –1.08, p = .282; gains total reading time: Z = –3.30, p = .741)"
Discussion¶
Related Claims¶
- Reading times for unknown words decrease significantly after three to four encounters, and by eight encounters unknown words are read like known words — related
- The more often learners meet a word while reading, the more likely they are to learn it incidentally; a meta-analysis of correlational studies finds a moderate correlation — related
- L2 learners pick up vocabulary incidentally from meaning-focused input, with reading the most-studied mode and listening yielding similar proportions of words learned — related
- Unknown words are read significantly longer than known control words in all four eye-tracking measures — related
- Viewing a single full-length L2 TV program results in incidental vocabulary learning at the level of meaning recall and meaning recognition — related
- Vocabulary Knowledge Grows Incrementally With Repeated Encounters In Varied Contexts — a broader claim this one bears on
- First language evidence shows extensive reading for meaning leads to vocabulary acquisition over time, probably accounting for most L1 vocabulary growth beyond the first few thousand common words — related
