RESUMEN

We investigated age-related differences in serial and strategic processing during the encoding and retrieval of high-value words. Younger and older adults were presented with word triads positioned left, center, and right, with one word being more valuable than the others. In Experiment 1, younger adults more effectively recalled the middle, high-value word, demonstrating enhanced strategic memory. Younger adults were more likely to initiate recall with a high-value word whereas older adults were equally likely to initiate recall with a left and high-value word. Additionally, older adults were more likely to recall words in their presented order while younger adults strategically recalled successive high-value words. However, both age groups demonstrated strategic processing in Experiments 2 and 3, even without prior knowledge of the high-value word's location. Thus, serial and strategic processing may differ based on age and task demands, but strategic processing is preserved in older adults in certain contexts.

RESUMEN

People often engage in the selective remembering of valuable or important information, whether strategic and/or automatic. We examined potential age-related differences in the automatic processing of value during encoding on later remembering by presenting participants with words paired with point values (range: 1-10 twice or 1-20) to remember for a later test. On the first three lists, participants were told that they would receive the points associated with each word if they recalled it on the test (their goal was to maximize their score). On the last three lists, we told participants that all words were worth the same number of points if recalled on the tests, thus making the point value paired with each word meaningless. Results revealed that selective memory may be impaired in older adults using procedures with larger value ranges. Additionally, we demonstrated that the automatic effects of value may have a greater effect on younger adults relative to older adults, but there may be instances where older adults also exhibit these automatic effects. Finally, strategic and automatic processes may not be related within each learner, suggesting that these processes may rely on different cognitive mechanisms. This indicates that these processes could be underpinned by distinct cognitive mechanisms: strategic processes might engage higher-level cognitive operations like imagery, while automatic processes appear to be more perceptually driven.

RESUMEN

People are often presented with large amounts of information to remember, and in many cases, the font size of information may be indicative of its importance (such as headlines or warnings). In the present study, we examined how learners perceive the importance of information in different font sizes and how beliefs about font size influence selective memory. In Experiment 1, participants were presented with to-be-remembered words that were either unrelated or related to a goal (e.g., items for a camping trip) in either small or large font. Participants rated words in large font as more important to remember than words in small font when the words in a list were unrelated but not when the words were schematically related to a goal. In Experiments 2 and 3, we were interested in how learners' belief that font size is indicative of importance translates to their ability to selectively encode and recall valuable information. Specifically, we presented participants with words in various font sizes, and larger fonts either corresponded to greater point values or smaller point values (values counted towards participants' scores if recalled). When larger fonts corresponded with greater point values, participants were better able to selectively remember high-value words relative to low-value words. Thus, when to-be-remembered information varies in value, font size may be less diagnostic of an item's importance (the item's importance drives memory), and when the value of information is consistent with a learner's belief, learners can better engage in selective memory.

RESUMEN

Increasingly large and frequent wildfires affect air quality even indoors by emitting and dispersing fine/ultrafine particulate matter known to pose health risks to residents. With this health threat, we are working to help the building science community develop simplified tools that may be used to estimate impacts to large numbers of homes based on high-level housing characteristics. In addition to reviewing literature sources, we performed an experiment to evaluate interventions to mitigate degraded indoor air quality. We instrumented one residence for one week during an extreme wildfire event in the Pacific Northwest. Outdoor ambient concentrations of PM2.5 reached historic levels, sustained at over 200 µg/m3 for multiple days. Outdoor and indoor PM2.5 were monitored, and data regarding building characteristics, infiltration, and mechanical system operation were gathered to be consistent with the type of information commonly known for residential energy models. Two conditions were studied: a high-capture minimum efficiency rated value (MERV 13) filter integrated into a central forced air (CFA) system, and a CFA with MERV 13 filtration operating with a portable air cleaner (PAC). With intermittent CFA operation and no PAC, indoor corrected concentrations of PM2.5 reached 280 µg/m3, and indoor/outdoor (I/O) ratios reached a mean of 0.55. The measured I/O ratio was reduced to a mean of 0.22 when both intermittent CFA and the PAC were in operation. Data gathered from the test home were used in a modeling exercise to assess expected I/O ratios from both interventions. The mean modeled I/O ratio for the CFA with an MERV 13 filter was 0.48, and 0.28 when the PAC was added. The model overpredicted the MERV 13 performance and underpredicted the CFA with an MERV 13 filter plus a PAC, though both conditions were predicted within 0.15 standard deviation. The results illustrate the ways that models can be used to estimate indoor PM2.5 concentrations in residences during extreme wildfire smoke events.

RESUMEN

We often encounter more information than we can remember, making it critical that we are selective in what we remember. Being selective about which information we consolidate into our long-term memory becomes even more important when there is insufficient time to encode and retrieve information. We investigated whether older and younger adults differ in how time constraints, whether at encoding (Experiment 1) or retrieval (Experiment 2), affect their ability to be selective when remembering important information that they need to recall later. In Experiment 1, we found that younger and older adults exhibited similar selectivity, and the participants remained selective when rushed at encoding. In Experiment 2, older adults maintained their selectivity when given insufficient time at retrieval, but younger adults' selectivity was increased when given limited recall time. Altogether, the present experiments provide new support for negligible, and in some cases, even beneficial, effects of time constraints on older and younger adults' ability to selectively encode and retrieve the most valuable information. These findings may provide insight into a mechanism that allows older adults to use their long-term memory efficiently, despite age-related cognitive declines, even when faced with constraining encoding and retrieval situations.

RESUMEN

We examined the effects of interference on value-based memory in younger and older adults by presenting participants with lists of words paired with point values counting toward their score if recalled. In Experiment 1, we created a situation where there was a buildup of interference such that participants could recall words from any studied list to earn points. However, to increase participants' motivation to combat interference, we told participants that if they recalled words from previously studied lists, those words would be worth double the original point value of the word. In Experiment 2, to examine age-related differences in the absence of any interference, participants studied and were tested on the same set of words throughout several study-test cycles. The buildup of interference caused by participants needing to recall both just-studied and previously studied words in Experiment 1 impaired selectivity in older adults relative to younger adults and this effect was particularly pronounced when considering the recall of just prior-list words. However, in the absence of interference, there was not an overall recall deficit or any selectivity impairments in older adults. Thus, proactive and retroactive interference seem to be largely responsible for age-related deficits in selective memory for important information.

RESUMEN

Value-directed remembering refers to the tendency to best remember important information at the expense of less valuable information, and this ability may draw on strategic attentional processes. In six experiments, we investigated the role of attention in value-directed remembering by examining memory for important information under conditions of divided attention during encoding and retrieval. We presented participants with lists of words of varying objective or subjective value and compared participants completing the study phase under full or divided attention, in addition to participants completing the testing phase under full or divided attention. Results revealed that certain forms of selectivity were impaired when attention was divided during encoding but not when attention was divided during retrieval. Participants initiated recall (i.e., probability of first recall [PFR]) with high-value words as well as with words they subjectively deemed important; these value-mediated PFR retrieval dynamics resisted influence from reduced attentional resources during encoding and retrieval. Thus, while value-directed remembering involves both strategic encoding and retrieval operations, attentional resources during encoding appear crucial for subsequent recollection of valuable and important information; however, attentional resources during retrieval may be less influential in strategic selective memory.

RESUMEN

The surface functionalisation of self-assembled colloidal quantum dot supraparticle lasers with a thrombin binding aptamer (TBA-15) has been demonstrated. The self-assembly of CdSSe/ZnS alloyed core/shell microsphere-shape CQD supraparticles emitting at 630 nm was carried out using an oil-in-water emulsion technique, yielding microspheres with an oleic acid surface and an average diameter of 7.3 ± 5.3 µm. Surface modification of the microspheres was achieved through a ligand exchange with mercaptopropionic acid and the subsequent attachment of TBA-15 using EDC/NHS coupling, confirmed by zeta potential and Fourier transform IR spectroscopy. Lasing functionality between 627 nm and 635 nm was retained post-functionalisation, with oleic acid- and TBA-coated microspheres exhibiting laser oscillation with thresholds as low as 4.10 ± 0.37 mJ·cm-2 and 7.23 ± 0.78 mJ·cm-2, respectively.

RESUMEN

While often showing associative memory deficits, there may be instances when older adults selectively remember important associative information. We presented younger and older adults with children they would be hypothetically babysitting, and each child had three preferences: a food they like, a food they dislike, and a food they are allergic to and must avoid. In Experiment 1, all foods associated with each child were simultaneously presented while in Experiments 2 and 3, participants self-regulated their study of the different preferences for each child. We were interested in whether people, particularly older adults who often display associative memory impairments, can prioritize the most important information with consequences for forgetting (i.e., allergies), especially with increased task experience. Overall, compared with younger adults, older adults were better at selectively studying and recalling the children's allergies relative to the other preferences, and these patterns increased with task experience. Together, the present results suggest that both younger and older adults can employ strategies that enhance the recall of important information, illustrating responsible remembering. Specifically, both younger and older adults can learn to self-assess and prioritize the information that they need to remember, and despite memory deficits, older adults can learn to employ strategies that enhance the recall of important information, using metacognition and goal-directed remembering to engage in responsible remembering.

RESUMEN

We examined whether framing younger and older adults learning goals in terms of maximizing gains or minimizing losses impacts their ability to selectively remember high-value information. Specifically, we presented younger and older adults with lists of words paired with point values and participants were either told that they would receive the value associated with each word if they recalled it on a test or that they would lose the points associated with each word if they failed to recall it on the test. We also asked participants to predict the likelihood of recalling each word to determine if younger and older adults were metacognitively aware of any potential framing effects. Results revealed that older adults expected to be more selective when their goals were framed in terms of losses, but younger adults expected to be more selective when their goals were framed in terms of gains. However, this was not the case as both younger and older adults were more selective for high-value information when their goals were framed in terms of maximizing gains compared with minimizing losses. Thus, the framing of learning goals can impact metacognitive decisions and subsequent memory in both younger and older adults.

RESUMEN

BACKGROUND AND PURPOSE: Despite the benefits of quality improvement (QI) training, there is a scarcity of information on QI teaching formats for undergraduate pharmacy education. The Evidence-based Practice for Improving Quality (EPIQ) workshop was evaluated as a teaching format for a group of multi-year undergraduate pharmacy students, assessing knowledge acquisition and learner reactions. EDUCATIONAL ACTIVITY AND SETTING: Using a convergent mixed-method analysis, 10-item pre- and post-workshop multiple-choice questionnaires measured students' knowledge acquisition of foundational QI concepts. A six-item pre- and post-workshop survey and a voluntary post-workshop focus group evaluated students' attitudes towards QI training and the teaching format. Mann-Whitney U non-parametric test was used to analyze the quantitative data, while thematic analysis was applied to analyze the qualitative data. FINDINGS: Twenty-nine pharmacy students participated in the workshop. There was a statistically significant improvement in pharmacy students' QI knowledge before and after participating in the workshop (77% vs. 86%, P = .008). The evaluation of the EPIQ teaching format resulted in three important findings: (1) undergraduate pharmacy students identified a QI learning need; (2) the EPIQ workshop effectively provided foundational QI literacy for all pharmacy student years using a "learning by sharing" methodology and pharmacy-specific case studies; and (3) interested students may benefit from an experiential elective to apply QI techniques. SUMMARY: The perceived value of QI training for pharmacy students using the EPIQ workshop was demonstrated: students expressed an interest in lifelong learning and a desire to pursue QI projects at school, during a clinical rotation, or at work.

RESUMEN

In a recently published study, (Parker, A., Parkin, A., & Dagnall, N. (2021). Effects of survival processing on list method directed forgetting. Memory (Hove, England), 29(5), 645-661) examined directed forgetting in a survival processing context using the list-method directed forgetting procedure. (Parker, A., Parkin, A., & Dagnall, N. (2021). Effects of survival processing on list method directed forgetting. Memory (Hove, England), 29(5), 645-661) found that the costs of directed forgetting were greater when engaging in survival processing than when making moving relevance or pleasantness ratings. However, according to most current accounts of directed forgetting, engaging in survival processing should not have enhanced the directed forgetting effect but rather should not have impacted the directed forgetting effect. In the present study, we further investigated how survival processing impacts directed forgetting using both the list (Experiment 1) and item method of directed forgetting (Experiment 2). In Experiment 1, we did not replicate the findings of (Parker, A., Parkin, A., & Dagnall, N. (2021). Effects of survival processing on list method directed forgetting. Memory (Hove, England), 29(5), 645-661) - that the directed forgetting effect is enhanced when engaging in survival processing. Rather, we demonstrated that making survival ratings and moving ratings yielded a similar cost of directed forgetting for List 1 items. In Experiment 2, survival processing provided an overall memory benefit (but not when recalling to-be-remembered and to-be-forgotten items in separate recall tests) but did not differentially impact to-be-remembered and to-be-forgotten words. Thus, we did not find evidence that survival processing influences directed forgetting.

RESUMEN

ABSTRACTIn reward-based learning and value-directed remembering, many different value structures for the to-be-remembered information have been used by researchers. I was interested in whether different scoring structures used in a value-directed remembering task impact measures of memory selectivity. Participants studied lists of words paired with point values and some lists included words paired with values ranging from 1 to 20, 1 to 10 (repeating twice), either a high value (10 points) or a low value (1 point), and either a high value (10 points), a medium value (5 points) or a low value (1 point). Results suggest that (1) in tests of free recall, if using a continuous value scale, the range of values matters in terms of selective memory, (2) analysing the selectivity index can yield different results than modelling item-level recall using point values (and the latter may be a preferable approach), (3) measures of selectivity using different value structures may lack construct validity when testing memory via recognition tests, and (4) the effect of value on memory is much larger on recall than recognition tests. Thus, I suggest that researchers carefully consider and justify the value structure used when examining selective memory for valuable information in list learning tasks.

RESUMEN

People can choose to use external memory aids and offload information to help them remember it, but it is unclear how objective and subjective value or importance influence offloading decisions in younger and older adults. We presented younger adults (n = 99; age range: 18-31) and older adults (n = 93; age range: 60-96) with items to remember for a later test and allowed them to offload a subset of the presented items. In Experiment 1, the to-be-remembered information was lists of associated words paired with point values counting toward participants' scores if recalled. In Experiment 2, the to-be-remembered information was lists of items along a theme, such as packing for vacation, which differed in subjective value. Results revealed that when words were paired with objective point values, younger adults were more selective in their offloading decisions and subsequent recall than older adults (i.e., younger adults were more likely to offload and recall high-value items than low-value items relative to older adults). When the to-be-remembered items instead differed in subjective value, older adults were more selective in their offloading decisions than younger adults. Specifically, older adults were more likely to offload words they rated as important relative to items they rated as less important while younger adults displayed the opposite pattern-younger adults were more likely to offload words they rated as less important compared with items they rated as more important. This difference in offloading tendencies when to-be-remembered information varies in subjective value may be indicative of older adults engaging in a form of metacognitive control that can help ensure the use of responsible remembering.

RESUMEN

Background: Quality Improvement (QI) is any systematic process that seeks to improve patient safety or clinical effectiveness in healthcare. Although hospital pharmacists positively contribute to QI initiatives, there is no information available regarding Canadian hospital pharmacists' involvement and perspectives with QI. Objectives: The primary objective of the study was to describe the QI experiences (including attitudes, enablers and barriers) of hospital pharmacists employed by the Lower Mainland Pharmacy Services (LMPS) in British Columbia. Methods: This research study used an exploratory cross-sectional survey. A 30-item survey was developed to measure QI experiences of hospital pharmacists including prior QI experiences, their attitudes towards pursuing QI initiatives, and their perceived enablers and barriers to participating in QI initiatives in hospital settings. Results: Forty-one pharmacists responded (response rate of 14%). Thirty-eight participants (93%) indicated that they were familiar with the concept of QI. All participants (100%) reported that it was important for pharmacists to be involved with QI despite the general lack of formal QI training among the participants, and 40 participants (98%) agreed that QI was necessary to advance patient care. Moreover, 21 participants (51%) showed interest in leading QI initiatives, while 29 (71%) would participate in QI initiatives. Participants identified several individual and organizational barriers that hindered hospital pharmacists from pursuing QI initiatives. Conclusion: Our findings suggest that hospital pharmacists in LMPS would like to be actively involved with QI initiatives; however, individual and organizational barriers must be addressed in order to facilitate widespread adoption of QI practices.

RESUMEN

Prior work has demonstrated that watching videos at faster speeds does not significantly impair learning in younger adults; however, it was previously unclear how increased video speed impacts memory in older adults. Additionally, we investigated the effects of increased video speed on mind-wandering. We presented younger and older adults with a pre-recorded video lecture and manipulated the video to play at different speeds. After watching the video, participants predicted their performance on a memory test covering the material from the video and then completed said memory test. We demonstrated that although younger adults can watch lecture videos at faster speeds without significant deficits in memory, older adults' test performance is generally impaired when watching at faster speeds. Additionally, faster playback speeds seem to reduce mind-wandering (and mind-wandering was generally reduced in older adults relative to younger adults), potentially contributing to younger adults' preserved memory at faster speeds. Thus, while younger adults can watch videos at faster speeds without significant consequences, we advise against older adults watching at faster speeds.

RESUMEN

BACKGROUND: Pharmacy has been recognized as a vital healthcare profession during the COVID-19 pandemic. The primary objective of the INSPIRE Worldwide survey was to determine the impact of COVID-19 on pharmacy practice and pharmacists' roles around the world. METHODS: A cross-sectional online questionnaire with pharmacists who provided direct patient care during the pandemic. Participants were recruited through social media, with assistance from national and international pharmacy organizations between March 2021-May 2022. The questionnaire was divided into (1) demographics, (2) pharmacists' roles, (3) communication strategies, and (4) practice challenges. The data were analyzed using SPSS 28, and descriptive statistics were used to report frequencies and percentages. RESULTS: A total of 505 pharmacists practicing in 25 countries participated. The most common role that pharmacists undertook was responding to drug information requests (90%), followed by allaying patients' fears and anxieties about COVID-19 (82.6%), and addressing misinformation about COVID-19 treatments and vaccinations (80.4%). The most common challenges were increased stress levels (84.7%), followed by medication shortages (73.8%), general supply shortages (71.8%), and inadequate staffing (69.2%). CONCLUSIONS: Pharmacists within this study were significantly impacted by the COVID-19 pandemic and took on new or adapted roles (e.g., providing COVID-specific information, managing patients' emotions, and educating on public health measures) to meet the needs of their communities. Despite, the significant challenges (e.g., increased stress, supply chain challenges, addressing misinformation, and staffing shortages) faced by pharmacists, they continued to put their patients' needs first and to provide pharmacy services.

RESUMEN

Older adults often face memory deficits in binding unrelated items. However, in situations such as preparing for foreign travel, a learner may be highly motivated to learn the translations of important words (e.g., "money"). In the present study, younger and older adults studied Swahili-English word pairs and judged the importance of knowing each pair if they were traveling to a foreign country. Generally, we expected older adults to display a memory deficit but for both younger and older adults' memory to be driven by the subjective importance of the to-be-learned information. Both younger and older adults' memory was related to their subjective importance ratings, suggesting that both age groups were able to engage in goal-based value-directed remembering. With increased task experience, older adults appeared to utilize a strategic approach in their study of the translations by spending more time studying the items relative to younger adults. Thus, despite associative memory deficits in older age, both younger and older adults can selectively remember subjectively important information such that older adults can effectively remember new vocabulary that is subjectively important and related to their future goals.
