This paper puts forward a research agenda in the area of explicit and implicit knowledge and learning of second or additional languages. Based on a brief overview of reliable findings as well as open questions in the field, three agenda items are highlighted. First, valid and reliable measures of explicit and, in particular, implicit knowledge and…

The present study used quantitative and qualitative measures to examine Iranian applied linguists' (mis-) conceptions of ethical issues in research. For this purpose, one hundred and twelve applied linguists completed a research ethics questionnaire constructed and validated by the researchers. In the follow-up qualitative phase, 15 applied…

Despite the prevalence of quantitative approaches in applied linguistics (AL) and second language acquisition (SLA) research (Gass, 2009), evidence indicates a need for improvement in analyzing and reporting SLA data (e.g., Larson-Hall & Plonsky, 2015). However, to improve quantitative research, researchers must possess the statistical…

This study examines the experiences and motivations of language and linguistics academics who have published in potential predatory journals (PPJs). A questionnaire was administered to 2,793 academics with publications in 63 language and linguistics PPJs, and 213 of them returned their responses. A subsample of the respondents (n = 21) also…

We report results from children learning to read in one of four different languages: Croatian, English, Estonian and Swedish. The languages all have an alphabetical script but vary greatly on the dimension deep-shallow (or complexity-simplicity, or opacity-transparency), i.e., how close orthography and phonology are related. These languages also…

Evidence from life science, cognitive science, and philosophy supports the hypothesis that knowledge is a central norm of the human practice of assertion. However, to date, the experimental evidence supporting this hypothesis is limited to American anglophones. If the hypothesis is correct, then such findings will not be limited to one language or…

This study reports findings from two truth value judgment experiments to address two research questions on Mandarin: (i) whether children and adults have the knowledge of the structural constraint Principle C in their pronoun resolution; and (ii) whether adults and children show the prohibition effect of the cyclic-c-command constraint or the QR…

This article presents a study of preschool-aged children's knowledge of the semantics of the negative polarity item (NPI) "any". NPIs like "any" differ in distribution from non-polarity-sensitive indefinites like "a": "Any" is restricted to downward-entailing linguistic environments (Fauconnier 1975, 1979;…
