4.1.1 Number of authors. If the number of the authors is two, they both are written each time. Note that an ampersand ‘&’ is used only in the parentheses. • (Sawada & Pizlo, 2008) • Sawada and Pizlo (2008) If the number of the authors is between and five, list them all the first time the reference is cited. • (Pizlo, Sawada, Li, Kropatsch, & Steinman, 2010) • Pizlo, Sawada, Li, Kropatsch, and Steinman (2010) After the first citation, only the first author's last name is written to cite the reference. Note that “et al.” is used to indicate that there are more than two authors. • (Pizlo et al., 2010) • Pizlo et al. (2010) If the number of the authors is six or more than six, only the first author's last name is written. • (Tsuruhara et al., 2010) • Tsuruhara et al. (2010) 4.1.2 Multiple references in a single pair of parentheses. Multiple references can be cited together in a single pair of parentheses, separated by a semi-colon ‘;’ if these references are cited for the same reason: e.g. (Sawada, 2010; Sawada & Pizlo, 2008). If they are cited for different reasons, they should be specified. • Relative orientations between two eyes can be computed from eight pairs of corresponding points in their retinal images using a line algorithm (Longuet-higgins, 1981; see also Thompson, 1959 for an earlier algorithm that is highly non-linear). However, it is rather good to cite them in different of parentheses. • Relative orientations between two eyes can be computed from eight pairs of corresponding points in their retinal images using a linear algorithm
1981) and from five pairs of the points using a non-linear algorithm (Thompson, 1959). 4.1.3 Multiple works by the same author/authors in the same year. If two of references were written by the same author/authors in the same year, they can be distinguished by lower-case letters (a, b, c) following the year: e.g. (Sawada, Li, & Pizlo, 2011a) and (Sawada, Li, & Pizlo, 2011b). 4.1.4 Translated and re-published articles. A translated or re-published reference is cited with a year of its original publication and that of the (e.g. Mach, 1906/1959). 4.2 References References in “References” section are listed using "hanging indent" style (0.5 in.). Single line space is used in References and every reference is separated by additional 6 pt from its following reference. In this file, style of references is specified as “HSE-Reference” using Microsoft Word. Authors of each reference are listed with their last names and initials of their first names (and those of their middle names): e.g. Pavlov I. P. The references are listed alphabetically based on the last names of their first authors. More specific cases are discussed below. 4.2.1 Number of authors. References can be categorized depending on number of authors: one to seven, and more than seven. If the number of the authors is seven or less than seven, all the authors are listed in the references (see Attneave, 1954 for one; Barlow & Reeves, 1979 for two; Chan, Pizlo, Chelberg, 2006 for three; Dzhafarov, Ünlü, Trendtel, & Colonius, 2011 for four; Enns, Austen, Lollo, Rauschenberger, & Yantis, 2001 for five; Feldman et al., 2013 for six; Gallivan et al., 2011 for seven authors in References). If the number of the authors is more than seven, only the first six authors and the last author are listed:
