In this commentary, I suggest that it may be helpful to think about the formidable problem space that Westergaard's (2021) Linguistic Proximity Model seeks to address at the three levels of analysis that Marr (1982) famously proposed are needed to understand any complex cognitive system. I argue that at the computational level of analysis, where…

Poverty of the stimulus has been at the heart of ferocious and tear-filled debates at the nexus of psychology, linguistics, and philosophy for decades. This review is intended as a guide for readers without a formal linguistics or philosophy background, focusing on what poverty of the stimulus is and how it's been interpreted, which is…

In this article, I argue that first language (L1), second language (L2) and third language (L3) acquisition are fundamentally the same process, based on learning by parsing. Both child and adult learners are sensitive to fine linguistic distinctions, and language development takes place in small steps. While the bulk of the article focuses on…

Second language acquisition has been observed to be variable in its outcome such that, unlike native speakers, all second language learners do not achieve total success. Second language acquisition is made of macro and micro processes. External and internal (e.g., age, individual differences) factors are assumed to affect language processing in…

Israel has two official languages: Hebrew and Arabic, and one semi-official language, English. Within this multilingual environment, the national English curriculum relates to all learners as one homogenous population. There are no specific directives regarding the linguistic needs of diverse language backgrounds. Studies of literacy acquisition…

Across languages of the world, some grammatical patterns have been argued to be more common than expected by chance. These are sometimes referred to as (statistical) "language universals." One such universal is the correlation between constituent order freedom and the presence of a case system in a language. Here, we explore whether this…

Foreign language learning contrasts with native language development in two key respects: It is unreliable and it is nonconvergent. At the same time, it is clear that foreign languages are languages. The fundamental difference hypothesis (FDH) was introduced as a way to account for the general characteristics of foreign language learning. The FDH…

Examines assumptions about second language acquisition by means of the anatomical model described in Part 1 of the study (see vol. 6, no. 2 of this journal). The analysis shows that the assumptions are rooted in the Direct Method and that they retard learning. Implications for second language instruction are noted. (SED)

Truscott and Sharwood Smith (henceforth T&SS) propose a novel theory of language acquisition, "Acquisition by Processing Theory" (APT), designed to account for both first and second language acquisition, monolingual and bilingual speech perception and parsing, and speech production. This is a tall order. Like any theoretically ambitious…

This study attempts to assess the developmental psycholinguistics hypothesis that language acquisition strategies are universal. Four types of statements were focused upon: (1) true affirmative statements (e.g., "You are a child"), (2) false affirmative statements ("You are a baby"), (3) false negative statements ("You aren't a child"), and (4)…

Studies were conducted to help determine criteria for describing the stages through which second language learners pass as they acquire a new language. The ability of 24 beginning adult students of English as a second language to supply ten morphemes in obligatory contexts was predicted on the basis of contrastive analysis between English and each…
