What do novice word learners know about the sound of words? Word‐learning tasks suggest that young infants (14 months old) confuse similar‐sounding words, whereas mispronunciation detection tasks suggest that slightly older infants (18–24 months old) correctly distinguish similar words. Here we explore whether the difficulty at 14 months stems from infants' novice status as word learners or whether it is inherent in the task demands of learning new words. Results from 3 experiments support a developmental explanation. In Experiment 1, infants of 20 months learned to pair 2 phonetically similar words to 2 different objects under precisely the same conditions that infants of 14 months (Experiment 2) failed. In Experiment 3, infants of 17 months showed intermediate, but still successful, performance in the task. Vocabulary size predicted word‐learning performance, but only in the younger, less experienced word learners. The implications of these results for theories of word learning and lexical representation are discussed.
Objective
To examine whether meta-cognitive psychological skills, acquired in MBCT are also present in patients receiving medication treatments for prevention of depressive relapse and whether these skills mediate MBCT's effectiveness.
Method
This study, embedded within a randomized efficacy trial of MBCT, was the first to examine changes in mindfulness and decentering during 6-8 months of antidepressant treatment and then during an 18 month maintenance phase where patients either discontinued medication and received MBCT, continued on antidepressants, or were switched to a placebo. A total of 84 patients (mean age 44, 58% female) were randomized to one of these three prevention conditions. In addition to symptom variables, changes in mindfulness, rumination and decentering were assessed during the phases of the study.
Results
Pharmacological treatment of acute depression was associated with reductions in Rumination and increased Wider Experiences. During the maintenance phase, only patients receiving MBCT showed significant increases in the ability to monitor and observe thoughts and feelings as measured by the Wider Experiences (p<.01) and Decentering (p<.01) subscales of the Experiences Questionnaire and Toronto Mindfulness Scale. In addition, changes in Wider Experiences (p<.05) and Curiosity (p<.01) predicted lower HRSD scores at 6 months follow up.
Conclusions
An increased capacity for decentering and curiousity may be fostered during MBCT, and underlie its effectiveness. With practice, patients can learn to counter habitual avoidance tendencies and to regulate dysphoric affect in ways that support recovery.
Tumours frequently activate genes whose expression is otherwise biased to the testis,
collectively known as cancer–testis antigens (CTAs). The extent to which
CTA expression represents epiphenomena or confers tumorigenic traits is unknown. In
this study, to address this, we implemented a multidimensional functional genomics
approach that incorporates 7 different phenotypic assays in 11 distinct disease
settings. We identify 26 CTAs that are essential for tumor cell viability and/or are
pathological drivers of HIF, WNT or TGFβ signalling. In particular, we
discover that Foetal and Adult Testis Expressed 1 (FATE1) is a key survival factor
in multiple oncogenic backgrounds. FATE1 prevents the accumulation of the
stress-sensing BH3-only protein, BCL-2-Interacting Killer (BIK), thereby permitting
viability in the presence of toxic stimuli. Furthermore, ZNF165 promotes
TGFβ signalling by directly suppressing the expression of negative feedback
regulatory pathways. This action is essential for the survival of triple negative
breast cancer cells in vitro and in vivo. Thus, CTAs make significant
direct contributions to tumour biology.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
