“…An alternative is to intervene on the language system with downstream gains in VWM. Interventions focused on improving phonological abilities have been shown to benefit VWM capacity (Gillam et al, 2018), a finding consistent with the significant role of PA in our study. Research is needed to determine which intervention approaches result in well-maintained, functional language gains.…”

“…Intervention to remediate VWM limitations is an active area of research. The evidence supporting intervention in VWM is controversial as researchers debate whether immediate gains in VWM result in downstream gains in functional language ability (Gillam, Holbrook, Mecham, & Weller, 2018). An alternative is to intervene on the language system with downstream gains in VWM.…”

Verbal working memory (VWM) deficits are common in individuals with developmental language disorder (DLD) but are not well understood. This study evaluated how both memory and language production factors influence VWM performance in children and adults with DLD, focusing on the influence of serial position, phonological activation (PA), and lexical frequency. Participants were 30 children with DLD and 26 with typical language, and 21 adults with DLD and 23 with typical language. The participants completed a listening span task in which they were asked to recall the final words of sentences in sets of increasing size. Responses (dependent variable) were coded as correct, incorrect, or no response. Final words were coded for frequency, serial position within the set, and PA (number of occurrences of the initial phoneme, vowel, and whole word in the task). These variables, along with age and language status, were entered as predictors in mixed-effects multinomial regression models. Extreme serial position, greater PA, and higher frequency reduced incorrect and no responses. These effects were attenuated for the DLD group, and the effect of greater PA varied with set size. The findings suggest that for individuals with DLD, VWM performance is affected by more limited effective language experience and by the dynamic task demands.

“…Funnel plot of observed outcomes (gs) and standard errors of very-near-transfer measures at follow-up. 6 Interestingly, the lack of follow-up far-transfer effects also seems to reject the hypothesis that some time is needed in order for generalized results reported in most recent meta-analyses and systematic reviews in the broader field of WM training (e.g., Dougherty, Hamovits, & Tidwell, 2016;Gillam, Holbrook, Mecham, & Weller, 2018;Melby-Lervåg et al, 2016;Sala & Gobet, 2017a, b;Soveri, Antfolk, Karlsson, Salo, & Laine, 2017). Conversely, our findings contradict the more optimistic conclusions of those meta-analyses and systematic reviews specifically examining the impact of CWMT on far-transfer measures (Nutley & Ralph, n.d.;Pearson, 2016;Shinaver et al, 2014;Spencer-Smith & Klingberg, 2015).…”

Cogmed Working Memory Training (CWMT) is a commercial cognitive-training program designed to foster working-memory capacity. Enhanced working-memory capacity is then supposed to increase one’s overall cognitive function and academic achievement. This meta-analysis investigates the effects of CWMT on cognitive and academic outcomes. The inclusion criteria were met by 50 studies (637 effect sizes).Highly consistent near-zero effects were estimated in far-transfer measures of cognitive ability (e.g., attention and intelligence) and academic achievement (language ability and mathematics). By contrast, slightly heterogeneous small to medium effects were observed in memory tasks (i.e., near transfer). Moderator analysis showed that this effect was weaker for near-transfer measures not directly related to the trained tasks. These results highlight that while near transfer occurs regularly, far transfer is rare or, possibly, nonexistent. Transfer thus appears to be a function of the degree of overlap between trained tasks and outcome tasks.

“…Another way to reduce negative environmental impacts is to avoid reprocessing raw material or subproducts due to operations poorly done (Abed et al, 2020 ). Also, notifications are not made to the operator through Andon, and production lines continue with defective products identified in the market or subsequent processes (Gillam et al, 2018 ). The maquiladora industry has a high level of human labor, where human errors in operations can generate much waste that can be avoided through Poka-yoke, visual management, or Andon.…”

The Mexican maquiladora industry is applying Lean Manufacturing Tools (LMT) in its production lines; however, few studies have investigated its relationship with sustainability (social, economic, and environmental). This paper presents a second-order structural equation model (SEM) relating 8 LMT integrated into three independent latent variables: continuous improvement (Kaizen and Gemba), supporting tools (Andon, visual management, and Poka-yoke), and machinery and equipment (total productive maintenance, overall equipment effectiveness, and Jidoka) that are related to social, economic, and environmental sustainability as dependent variables. The model is validated with information obtained from 249 companies using partial least squares. Findings show that the application of LMT in the Mexican maquiladora industry avoids the generation of waste and reprocessing. Likewise, the improvement of production processes reduces the waste emitted into the environment and reduces energy consumption. Also, when companies have environmental programs, the work environment is safe, and labor relations are improved, increasing morale and the commitment to work for the company, gaining economic and ecological benefits.
