We developed a novel, unobtrusive estimate of team multitasking throughput (tMT). We demonstrate it through the quantitative assessment of tMT in distributed dyads when objective performance and purported reliability are manipulated among teammates. In a within-subjects experiment, we investigated the effects of teammates' performance and purported reliability on tMT. Results showed that when a teammate was described as reliable, there was a marked difference in tMT between those with low and high objective performance, but this difference was not present for teammates described as unreliable. Further, after considering the expected differences between high and low performing teams, we found partial support that tMT was highest when performance matched (vs. violated) expectation. These findings evidence the utility of our novel metric to capture team performance. In conclusion, we quantified how objective performance and purported reliability dynamically affect team efficiency while completing collaborative tasks. We found there was a marked difference in tMT between those with low and high purported reliability, but this difference was dependent on whether the teammate's performance matched expectations.

We investigated the influence of childhood poverty on financial decision making under threat by replicating the findings of Griskevicius et al. (2011b), which found that individuals from lower socioeconomic backgrounds tend to make riskier financial decisions and prefer immediate over delayed gratification when exposed to mortality cues. Following an extension of life history theory to individual behaviors, the original research argued that these behaviors reflect a faster and riskier strategy to cope with survival threats. In a preregistered replication using the same procedures and instruments as the original study, we tested this hypothesis with a sample size 14.2 times larger than the original (1,010 vs. 71). We replicated the effect of mortality salience on risk-taking for people who experienced childhood poverty but with a substantially smaller effect size (η² = 0.004 vs. η² = 0.17 in the original). We failed to find any effect on time preferences in contrast to the original study's medium effect size (η² = 0.046). Although our findings partially support the results of Griskevicius et al. (2011b) on poverty and financial decision making, the drastically reduced effect sizes challenge the practical significance of these findings. Our replication results underscore the importance of large sample studies in understanding the effects of childhood socioeconomic status on future life decisions. They also suggest that frameworks beyond life history theory may be needed to reliably capture such relationships. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Understanding speech in noisy environments is often challenging, but is easier if we are listening to someone familiar-for example, naturally familiar people (e.g., friends, partners) or voices that have been familiarized artificially in the lab. Thus, familiarizing people with voices they regularly encounter (e.g., new friends and colleagues) could improve speech intelligibility in everyday life, which might be particularly useful for people who struggle to comprehend speech in noisy environments, such as older adults. Yet, we do not currently understand whether computer-based voice familiarization is effective when delivered remotely, outside of a lab setting, and whether it is effective for older adults. Here, in an online computer-based study, we examined whether learned voices are more intelligible than unfamiliar voices in 20 older (55-73 years) and 20 younger (18-34 years) adults. Both groups benefited from training, and the magnitude of the intelligibility benefit (approximately 30% improvement in sentence report, or 9 dB release from masking) was similar between groups. These findings demonstrate that older adults can learn new voices as effectively as younger adults for improving speech intelligibility, even given a relatively short (< 1 hr) duration of familiarization that is delivered in the comfort of their own homes.

Fuzzy-trace theory (FTT) posits that people share misinformation online if it promotes gist mental representations, cuing motivationally relevant values. Most people value the truth. Thus, per FTT, people decide to share messages that they perceive as true. FTT also predicts that messages will be more effective if they communicate a simple gist. We test these predictions by examining the roles of mental representation and epistemic quality in decisions to share misinformative articles on Facebook across two experiments and two correlational studies. In Studies 1 and 2, we use Facebook data to test the hypothesis that gist proxies in text are associated with online sharing. In Study 3, we experimentally manipulate subjects' exposure to a gist-based intervention that explains why a misinformative article is false, a simple debunk stating only that the article is false (but not explaining why) and a verbatim condition providing relevant detailed information but allowing subjects to draw their own conclusions. We found that the gist condition decreased intentions to share misinformation. Finally, in Study 4, we replicated this finding and showed that the gist condition also reduces misinformation endorsement. Results provide support for FTT's predictions regarding reducing sharing and endorsement of misinformation on social media. (PsycInfo Database Record (c) 2025 APA, all rights reserved).

Prior research has investigated ways to optimize identification performance, but an open question concerns exactly what variable should be optimized. One reasonable way to optimize performance is to maximize discriminability, which is achieved by increasing correct identifications of guilty suspects while simultaneously decreasing false identifications of innocent suspects. Another reasonable way to optimize performance is to maximize the information about the guilt or innocence of the suspect, which is best achieved by ensuring that a confidence rating is always made to the suspect. In a typical lineup, however, limited information about the suspect is obtained if the witness picks a filler or rejects the lineup. One proposed solution to that problem is to have the witness provide a confidence rating to every member of the lineup (a rate-them-all lineup). But what effect, if any, does a rate-them-all procedure have on discriminability? To answer that question, we compared a rate-them-all lineup procedure to standard simultaneous lineup and showup procedures using receiver operating characteristic analysis. In terms of discriminability, the rate-them-all procedure was diagnostically inferior to both. A reasonable goal for future research is to make use of theoretical models of eyewitness identification to simultaneously maximize both discriminability and information gain.

This eye tracking study run in 2019 examines the learning benefits of two common active learning approaches-generating predictions and retrieval practice-for young children. Both generating predictions and retrieval practice are active learning approaches that involve generating responses and then being provided with the correct information or retrieving previously provided correct information. Participants included 90 children (M_age = 7 years; female = 46, male = 42). Parents reported children's race and ethnicity as follows: 2% Asian/Pacific Islander, 5% African American, 74% Caucasian, 3% other, and 6% identified as two or more categories; demographics largely reflective of the county where the data were collected, but nevertheless the generalizability of these findings to more diverse populations may be limited. In this study, young children learned facts about insects (e.g., "Insects are hard on the outside.") while we measured their attention to the lesson using eye tracking technology. Then their knowledge was assessed on an immediate test. All children were presented with the same materials, but the presentation order was modified based on condition assignment. In the generating predictions condition, children saw examples of animals and were asked if an animal was an insect or they saw animals and were asked to identify which one was the insect, followed by the correct response. In the retrieve condition, the presentation order was reversed such that children first saw the correct response and then were asked if the animal was an insect, or which of two examples was an insect. Results suggest that although retrieval practice results in overall better learning outcomes, generating predictions increased children's attention to the materials (d = 1.92), and among children who were able to maintain attention, learning outcomes were equal among the two conditions in an immediate test. This work highlights the importance of considering student-level factors when deciding the best learning strategies to implement. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

It is commonly claimed that higher domain knowledge enhances new learning-the knowledge-is-power hypothesis. However, a recent meta-analysis (Simonsmeier et al., 2022) has challenged this idea, finding no overall relationship between prior knowledge and new learning across hundreds of highly variable effect sizes. The authors note that this variability and lack of randomized controlled experiments preclude broad claims regarding the influence of prior knowledge on learning. The present study (conducted in 2020) provides an experimental assessment of the causal effect of prior domain knowledge on new learning. Participants were randomly assigned to receive training in one of two academic domains over 3 days before learning new information about topics in both domains for a later test. Training was specific to three of four topics within that domain, allowing the untrained topic in the trained domain to act as a measure of new learning in that domain. New learning, measured as final test performance or knowledge gains, did not differ between the high and low domain knowledge conditions. Experimentally induced prior domain knowledge did not affect new learning. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Is confidence most diagnostic of accuracy when expressed in numbers or when expressed in words? This question bears immense importance in many real-world contexts especially within the confines of eyewitness identification. In an eyewitness identification task, we compared the diagnostic value of numeric confidence across rating scales that varied in grain size (3-point vs. 6-point vs. 21-point vs. 101-point rating scales). We also compared the diagnostic value of numeric confidence to verbal confidence statements using several machine-learning algorithms. We found that fine-grain ratings are more diagnostic of identification accuracy than coarse-grain ratings, which suggests that the former provides a closer correspondence to memory strength than the latter. Moreover, we found that verbal confidence statements capture diagnostic information about the likely accuracy of an identification that numeric confidence ratings do not capture. This suggests that verbal confidence statements and numeric confidence ratings reflect partially independent, nonoverlapping sources of information. These results shed light on the processes that provide diagnostic value to confidence. From an applied standpoint, these results suggest that verbal confidence statements and numeric confidence ratings ought to be collected from eyewitnesses after an identification decision. Collecting both captures more diagnostic information than either can capture in isolation. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

There is a major shift taking place in airports across the globe, changing from 2D dual-view X-ray screening to 3D computed tomography (CT) screening. 3D CT screening is believed to improve target detection since it enables screeners to interact with images of passenger baggage (i.e., rotating and zooming into the displays). The change in screening technology is moving what was once a purely visual search task to an interactive search task. Here, we conducted two experiments with a large sample size during February of 2023 (695 participants) to examine (a) changes in search performance between a simulated dual-view and simulated interactive search task and (b) the effects of time on task upon performance. Consistent with past research, we found that interactive search, when compared with dual-view search, produced higher response accuracy rates coupled with increased reaction times (RTs). However, while we found effects of time on task (RTs reduced, and participants became more likely to respond "absent" as the experiments progressed), there was no evidence that these effects differed across simulated dual-view and simulated interactive searches. The results are discussed in relation to benefits of interactive search for supporting target detection by airport screeners. (PsycInfo Database Record (c) 2024 APA, all rights reserved).
