About this site
This is a website that supplements Language Faculty Science (Cambridge University Press).
It contains the design and the results of every Experiment discussed in the book, and also those of the Experiments mentioned only very briefly in the book.
In the CUP book, the Experimental results are provided only in a summary format. At this website, I provide the full information about the Experiments so as to make it possible for interested people to check the empirical/experimental basis presented in the book for the proposed methodology for language faculty science.
The information at this site is not intended to be self-contained. However, some explanation is provided for how to read the various charts given here. The references to (a section of) a chapter below are all to the CUP book, unless otherwise specified.
How to read various charts
How to read the various types of charts (Design, Examples, Result Charts, Informant Lists, and Raw Data) is provided here. For those who might find it useful to have its Japanese translation, its Japanese translation is provided here (日本語版). Also available are the Japanese version of Ch. 1 (日本語版) and the Japanese version of Ch. 8.2 (日本語版) of Language Faculty Science.
We combine the results of the one-sentence-at-a-time test type and three-sentences-at-a-time test type, focusing on just the Yes/No test type, because the choice between the two does not seem to result in a significant difference, as illustrated by the result charts under English EPSAs -1, -4, -7 and Japanese EPSAs -7, -10, and -9; see Ch. 5: Section 5.4.6.
Design, Examples and Results
Each EPSA-Experiment page has at least the following four sections: (i) Design, (ii) Examples, (iii) Results, and (iv) Raw Data. "Design" gives information about what SG(s) and LG(s) are employed in each EPSA Experiment, thereby specifying its design. The "Design" chart is, at least initially, not meant to public viewing and basically for the designer of the EPSA Experiment and his/her colleagues. For this reason the "Design" chart is not self-explanatory or self-contained. In relation to the preparation of the CUP book, eforts have subsequently been made to improve on the "readability" of the "Design" chart. The "Design" charts for many Japanese EPSA Experiments, however, still contain Japanese expressions. The "Examples" chart lists the Examples used in the EPSA Experiment. When a certain SG(s) or LG(s) are excluded from consideration, the Examples of such SG(s) or LG(s) are also excluded in the "Examples" chart. It should not be difficult to construct the excluded Examples based on the information provided in the "Design" chart. The informant judgments in the "Raw Data" chart include those on the excluded Examples as well. The excluded Examples can be made available upon request. In addition to various "Result" charts, along with informant-classification charts when applicable, each EPSA-Experiment page provides its "Raw Data" chart that contains all the judgments reported by the informants, including their "time stamp."
The concepts/terms that seem most crucial in understanding the result charts are explained here. This pdf file provides a full list of Glossary entries.
The result charts for EPSA  only include the judgments by native speakers of English. The informant classification code for "Native speakers of English" is "r2," and that is indicated for each result chart for EPSA .
The design and the Examples of each EPSA Experiment under EPSA  include all the Schema groups and all the Lexical groups. However, not all of them are considered in the CUP book. In the case of EPSA -4 and EPSA -5, for example, Schema group 3 is always ignored in the CUP book, because it is not part of the main concern of the Experiments as discussed in the book.
Almost all the informants in these Experiments were students in a large undergraduate General Education course in Linguistics at the University of Southern California in the spring semester of each of the 2011-2014 academic years. The students were asked to participate in the same set of on-line Experiments twice during the semester, at the beginning and in the later part of the semester. For the purpose of keeping the results of the two rounds of Experiment-participation separately, the Experiments in the first and the second rounds are given different Experiment numbers. EPSA -1, -2, -3, -4, -5, and -7 in the first round are called EPSA -8, -9, -10, -11, -12, and -13, respectively, in the second round. Both rounds of Experiments were conducted before any discussion about what hypotheses were being considered and what predictions were being tested. After the first round and before the second round, there were lectures about set theory and quantification, where the "meaning" of every, no, and some was discussed, but not about what hypotheses or predictions the on-line Experiments were testing.
In the spring of 2012, participation in the first round was obligatory but the second round was optional, which resulted in not many students participating in the second round. In the springs of 2013 and 2014, participation in both the first and the second rounds was obligatory and the majority of the students participated in the Experiments in both rounds.
The Main Japanese EPSA Experiments discussed in the CUP book are those under EPSA  and EPSA . Their Sub-Experiments are EPSA -5, -10, and -11 and EPSA -7. EPSA -1 and -5 and EPSA -4 are only mentioned briefly and are not discussed in depth in the book. EPSA -3 is not mentioned in the book. (See below for further remarks on EPSA -1, -3, and -5.) The result charts at this website of Experiments under EPSA , EPSA , EPSA , EPSA , EPSA , and EPSA  only include the judgments by native speakers of Japanese, as in the case of the book. The informant classification code for "Native speakers of Japanese" is "r1," and that is indicated for each result chart of the Japanese EPSA Experiments provided here.
The design and the Examples of each of these EPSA Experiments include all the Schema groups (SGs) and all the Lexical groups (LGs), except for EPSA -7 and EPSA -18. Only LG3 and LG4 are included in EPSA -7 here, as in the case of the CUP book, because the Examples of the other LGs (Lexical groups 1, 2, 5, and 6) were not used in the actual Experiments so as to keep the total number of Examples small enough. In the case of EPSA -18, all the SGs were included in the actual Experiment, but only SG1 and SG2 are considered in the result charts in the CUP book in order to make comparison among different EPSA Experiments straightforward; see Ch. 7: section 5. The results charts of EPSA -18 here also include SG1 and SG2 only. (But the "Raw Data" include the informant judgments on the Examples of the other SGs.)
The Examples of the Japanese EPSA Experiments are given as the informants see them, hence without their English translations. Based on the SG(s) and the LG(s) for each Experiment, as provided in the book, the non-native speaker/reader of Japanese should be able to figure out the relevant properties of each Example. That, however, would require efforts. To reduce the "workload" of the non-native speaker/reader of Japanese at least to some extent, I provide at the top of the page for each Japanese EPSA Experiment what its SG(s) and LG(s) are in their English translations if applicable.
Almost all the informants in these Experiments were students in undergraduate courses at various (about 10) universities in Japan. They participate in EPSA Experiments as part of their course activities, either as an optional task or a required task for the course grade. Most of those undergraduate students have had little or no linguistics background prior to participating in EPSA Experiments. The undergraduate courses they attend do not include any discussion about what hypotheses and predictions are being tested in the Experiments before or after their participation in the EPSA Experiments.
Experiments on the lexical hypotheses (a-NP vs. so-NP)
Experiment on the singular-denoting nature of soko and soitu
Experiments on the LF c-command condition on FD
Experiments on the language-particular hypothesis about otagai
The following Experiments are made reference to but not discussed in the CUP book; see p. 370 n. 96. A draft of the CUP book contained an Appendix on otagai but it has been removed due to the space limit. I plan to make the Appendix available here soon, which refers to the Experiments below.
Experiment on local disjointness effects in Japanese
The result of this Experiment is briefly mentioned in p. 371-372 n. 98.
Requests for having additional charts at this website
The charts provided here are those discussed or mentioned in the CUP book. They are among many other result charts that could have been discussed. The particular selection of the result charts and the informant-classification charts is in part due to space/time considerations, and I plan to add more charts at this website as I find their addition to be useful to the reader of the book. If you would like to have other result charts or informant-classification charts added to this website, please email me your requests, along with a brief reason for their addition.
Remarks on the forthcoming books
There are multiple book projects following Hoji 2015. In the next book, I will try to provide further illustration and demonstration of the viability of language faculty science as an exact science as outlined in Hoji 2015. I will discuss in some depth my own single-researcher-informant experiment. This is in line with the internalist thesis, according to which the experimental task of a language faculty scientist should start with one's own single-researcher-informant experiment.
