It has been widely established that depressed mood states and clinical depression, as well as a range of other psychiatric disorders, are associated with a relative difficulty in accessing specific autobiographical information in response to emotion-related cue words on an Autobiographical Memory Test (AMT; J. M. G. Williams & K. Broadbent, 1986). In 8 studies the authors examined the extent to which this relationship is a function of impaired executive control associated with these mood states and clinical disorders. Studies 1–4 demonstrated that performance on the AMT is associated with performance on measures of executive control, independent of depressed mood. Furthermore, Study 1 showed that executive control (as measured by verbal fluency) mediated the relationship between both depressed mood and a clinical diagnosis of eating disorder and AMT performance. Using a stratified sample in Study 5, the authors confirmed the positive association between depressed mood and impaired performance on the AMT. Studies 6–8 involved experimental manipulations of the parameters of the AMT designed to further indicate that reduced executive control is to a significant extent driving the relationship between depressed mood and AMT performance. The potential role of executive control in accounting for other aspects of the AMT literature is discussed.
Using rules extracted from experience to solve problems in novel situations involves cognitions such as analogical reasoning and language learning and is considered a keystone of humans' unique abilities. Nonprimates, it has been argued, lack such rule transfer. We report that Rattus norvegicus can learn simple rules and apply them to new situations. Rats learned that sequences of stimuli consistent with a rule (such as XYX) were different from other sequences (such as XXY or YXX). When novel stimuli were used to construct sequences that did or did not obey the previously learned rule, rats transferred their learning. Therefore, rats, like humans, can transfer structural knowledge from sequential experiences.
A number of studies claim that knowledge of 5,000-8,000 of the most frequent words should provide at least 95% coverage of most unsimplified texts in English, arguably enough to guess or ignore most unknown words while reading (hidden in that 95% figure are other kinds of words-multiword expressions-not accounted for by current estimates based on frequency lists. Such expressions are often composed of highly frequent words, and therefore it is possible that such items may go unnoticed by learners reading in the second language. To test this assertion, a two-part test was taken by 101 adult Brazilian learners of English: One part contained short texts composed of the top 2,000 words in English; the second part contained the exact same words, however the arrangement of these same words constituted multiword expressions (e.g., large, and, by R by and large). Tests of reading comprehension indicated that learners' comprehension not only decreased significantly when multiword expressions were present in text but students also tended to overestimate how much they understood as a function of expressions that either went unnoticed or were misunderstood.
Typical experiments investigating the accessibility and/or role of principles of Universal Grammar (UG) in adult second language acquisition (SLA) use a written grammaticality judgement (GJ) task to infer knowledge of principles of UG. This investigation examined whether subjects would judge sentences differently in the aural modality from the visual. It was hypothesized that subjects in the aural condition would be less accurate and slower at judging sentences than subjects in the visual condition. Four language groups were tested: ESL (English second language), FSL (French second language), L1.E (English first language) and L1.F (French first language). Subjects were assigned to either an aural or a visual condition. The target sentences presented to the subjects were declarative sentences involving embedded questions, as well as ungrammatical wh-questions which violated Subjacency. The presentation times for all sentences were matched across conditions. Accuracy and reaction time to grammaticality judgement were measured. The hypothesis that subjects would be slower and less accurate in the aural condition than the visual one was supported. Furthermore, subjects were less accurate and slower to judge violations of Subjacency than other sentences, in both modalities. The detrimental effects of the auditory task on judgements were most pronounced for the L2 learners. These results are discussed in the context of the informativeness and validity of outcomes derived from GJ tasks, and the ways in which they are presented.
This experiment investigated comprehension monitoring in children learningEnglish as an additional language (EAL) compared to monolinguals. Sixty-three 9-10-year-old children read texts containing an internal inconsistency (e.g. a barking kitten vs. barking puppy) while their eye movements were monitored.Standardized tests measured word reading fluency and vocabulary size and the children completed a questionnaire tapping rereading behavior. There was no overall difference between EAL and monolingual children. Regardless of EAL status, children with larger vocabularies were more efficient in their re-analysis of inconsistent information, as revealed by regressive eye movements. However, rereading of inconsistent vs consistent words in the eye movement record was not related to children's self-reported rereading, not providing any support for deliberate rereading. Our findings indicate that successful online monitoring relies on strong word knowledge leading to efficient processing of texts, both for bilingual and monolingual children, and beyond deliberate rereading.
Past research has indicated that L1 acquirers do not include regular plural [-s] inflection within compounds, whereas they do include irregulars. This article reports on further work investigating this issue in L2 acquisition. One hundred adolescent francophone ESL students and 15 adult native-speaker controls were required to generate novel compounds in English. The results indicated that although participants reliably included more irregular noun plurals in compounds than regulars, regular plurals were frequently found. The results are discussed in terms of whether both the dual-mechanism and level-ordering models are relevant in the domain of second language acquisition. The evidence does not unequivocally support either model; rather, the results may be best accounted for with a more associative model of language learning.The debate concerning the underlying representation of language continues to be relevant today 40 years after Chomsky's (1959) review of Skinner's (1957) Verbal Behavior.
