“…Previous research has found that younger participants can control the trade-off between quality and quantity in some visual WM tasks via verbal encoding (e.g., Ramaty & Luria, 2018;Zhang & Luck, 2011). If reliance on such verbal encoding differs systematically between age-groups-as our results indicate-this could be problematic for agecomparisons in a variety of visual WM tasks, for instance paradigms measuring visual feature-binding, if remembering individual features lends itself to such labeling and remembering bindings does not (Brockmole & Logie, 2013).…”

The decline of working memory (WM) is a common feature of general cognitive decline, and visual and verbal WM capacity appear to decline at different rates with age. Visual material may be remembered via verbal codes or visual traces, or both. Souza and Skóra, Cognition, 166, 277–297 (2017) found that labeling boosted memory in younger adults by activating categorical visual long-term memory (LTM) knowledge. Here, we replicated this and tested whether it held in healthy older adults. We compared performance in silence, under instructed overt labeling (participants were asked to say color names out loud), and articulatory suppression (repeating irrelevant syllables to prevent labeling) in the delayed estimation paradigm. Overt labeling improved memory performance in both age groups. However, comparing the effect of overt labeling and suppression on the number of coarse, categorical representations in the two age groups suggested that older adults used verbal labels subvocally more than younger adults, when performing the task in silence. Older adults also appeared to benefit from labels differently than younger adults. In younger adults labeling appeared to improve visual, continuous memory, suggesting that labels activated visual LTM representations. However, for older adults, labels did not appear to enhance visual, continuous representations, but instead boosted memory via additional verbal (categorical) memory traces. These results challenged the assumption that visual memory paradigms measure the same cognitive ability in younger and older adults, and highlighted the importance of controlling differences in age-related strategic preferences in visual memory tasks.

“…Here, the trade-off ability for VWM precision and number refers to a situation in which individuals adjust the VWM resource allocation voluntarily, while the lack of trade-off ability refers to a situation where individuals can only allocate VWM resource involuntarily. So far in the literature, there have been many studies on whether individuals could voluntarily trade off the VWM precision and number 19–28 , but the conclusion is still debated.…”

“…An alternative way to identify the critical factor affecting the trade-off is to examine the relation between trade-off tendency and individual ’s capacity. Although so far in the literature there have been many studies examining whether individuals could trade off the VWM precision and number 19–28 , surprisingly, the impact of individual’s VWM capacity on the trade-off ability of VWM precision and number have not been carefully examined.…”

Working memory capacity affects trade-off between quality and quantity only when stimulus exposure duration is sufficient: Evidence for the two-phase model

The relation between visual working memory (VWM) capacity and attention has attracted much interest. In this study, we investigated the correlation between the participants’ VWM capacity and their ability to voluntarily trade off the precision and number of items remembered. The two-phase resource allocation model proposed by Ye et al . (2017) suggests that for a given set size, it takes a certain amount of consolidation time for an individual to control attention to adjust the VWM resources to trade off the precision and number. To verify whether trade-off ability varies across VWM capacity, we measured each individual’s VWM capacity and then conducted a colour recall task to examine their trade-off ability. By manipulating the task requirement, participants were instructed to memorise either more colours in a low-precision way or fewer colours in a high-precision way. We conducted two experiments by adjusting stimulus duration to be longer than predicted critical value (Experiment 1) and duration shorter than predicted critical value (Experiment 2). While the results of Experiment 1 showed a positive correlation between the VWM capacity and trade-off ability, the results of Experiment 2 showed a lack of such correlation. These results are consistent with the prediction from the two-phase model.

This longitudinal study examined the effect of the Visual Memory Development Technique (VMDT) on the motivation of students with low proficiency to read in the EFL context. The sample population consisted of 64 Preparatory Year (PY) students at Najran University. All 64 students were given the Motivation for Reading in English Questionnaire (MREQ) to measure their motivation to read prior to the treatment (VMDT). The 64 students were divided into an experimental and a control group. Both groups received instructions for reading with their traditional remedial materials, but the experimental group's instruction was supplemented by the addition of the VMDT at the beginning of each reading class for twelve lessons over a six-week period. An exit slip was given to the students at the end of each lesson. After six weeks, the MREQ was administered to both groups to measure the change in the students' motivation to read in the English language. The results of the quantitative tool (MREQ) were analyzed via SPSS (Ver.16) and Excel (Ver. 2013), and the findings of the qualitative tools (experimentation and exit slips) were collected and analyzed using a thematic approach. The post-test result for the MREQ showed a significant difference in students' motivations (F ¼ 10, 21, p < 05). Based on the results, the students in the reading group that was given the VMDT at the beginning of the class showed increased motivation to read in the English language inside the classroom; suggestions and pedagogical implications are presented accordingly.
