Multidisciplinary learning through collective performance favors decentralization.

Many models of learning in teams assume that team members can share solutions or learn concurrently. However, these assumptions break down in multidisciplinary teams where team members often complete distinct, interrelated pieces of larger tasks. Such contexts make it difficult for individuals to separate the performance effects of their own actions from the actions of interacting neighbors. In this work, we show that individuals can overcome this challenge by learning from network neighbors through mediating artifacts (like collective performance assessments). When neighbors' actions influence collective outcomes, teams with different networks perform relatively similarly to one another. However, varying a team's network can affect performance on tasks that weight individuals' contributions by network properties. Consequently, when individuals innovate (through "exploring" searches), dense networks hurt performance slightly by increasing uncertainty. In contrast, dense networks moderately help performance when individuals refine their work (through "exploiting" searches) by efficiently finding local optima. We also find that decentralization improves team performance across a battery of 34 tasks. Our results offer design principles for multidisciplinary teams within which other forms of learning prove more difficult.

Shaping the future of kidney genetics in Australia: proceedings from the KidGen policy implementation workshop 2023.

The KidGen Collaborative's Policy Implementation Workshop 2023 celebrated the 10th anniversary of Australia's first kidney genetics clinic in Brisbane. This event marked the establishment of a national network now comprising 19 kidney genetics clinics across Australia, all dedicated to providing equitable access to genomic testing for families affected by genetic kidney diseases. The workshop reflected on past progress and outlined future objectives for kidney genetics in Australia, recognising the collaborative efforts of clinical teams, researchers, and patients. Key insights from the workshop are documented in the proceedings.

Time course of EEG power during creative problem-solving with insight or remote thinking.

Problem-solving often requires creativity and is critical in everyday life. However, the neurocognitive mechanisms underlying creative problem-solving remain poorly understood. Two mechanisms have been highlighted: the formation of new connections among problem elements and insight solving, characterized by sudden realization of a solution. In this study, we investigated EEG activity during a modified version of the remote associates test, a classical insight problem task that requires finding a word connecting three unrelated words. This allowed us to explore the brain correlates associated with the semantic remoteness of connections (by varying the remoteness of the solution word across trials) and with insight solving (identified as a Eurêka moment reported by the participants). Semantic remoteness was associated with power increase in the alpha band (8-12 Hz) in a left parieto-temporal cluster, the beta band (13-30 Hz) in a right fronto-temporal cluster in the early phase of the task, and the theta band (3-7 Hz) in a bilateral frontal cluster just prior to participants' responses. Insight solving was associated with power increase preceding participants' responses in the alpha and gamma (31-60 Hz) bands in a left temporal cluster and the theta band in a frontal cluster. Source reconstructions revealed the brain regions associated with these clusters. Overall, our findings shed new light on some of the mechanisms involved in creative problem-solving.

Aha! and D'oh! experiences enhance learning for incidental information-new evidence supports the insight memory advantage.

Research on creative problem-solving finds that solutions achieved via spontaneous insight (i.e., Aha! moment) are better remembered than solutions reached without this sense of epiphany, referred to as an "insight memory advantage." We hypothesized that the insight memory advantage can spread to incidental information encoded in the moments surrounding insight as well. Participants (N = 291) were first given Rebus puzzles. After they indicated that they had found a solution, but before they could submit this solution, they were presented with scholastic facts that were incidental and unrelated to the problem at hand. Participants indicated whether they reached the solution via either insight or a step-by-step analysis. Memory results showed better performance for incidental scholastic facts presented when problem solving was accompanied by a spontaneous (Aha! experience) and induced (D'oh! experience) insight compared with solutions reached with analysis. This finding suggests that the memory advantage for problems solved via insight spreads to other unrelated information encoded in close temporal proximity and has implications for novel techniques to enhance learning in educational settings.

The irreconcilability of insight.

We are said to experience insight when we suddenly and unexpectedly become aware of the solution to a problem that we previously took ourselves to be unable to solve. In the field of comparative cognition, there is rising interest in the question of whether non-human animals are capable of insightful problem-solving. Putative cases of animals demonstrating insight have generally attracted two types of criticism: first, that insight is being conflated with other cognitive capacities (e.g., causal cognition, or mental trial and error); and, second, that the relevant performances merely reflect associative learning-and on the received understanding of insight within comparative cognition, insight necessarily involves non-associative processes. I argue that even if we grant that some cases of animal insight do withstand these two criticisms, these cases of purported animal insight cannot shed light on the nature of insightful problem-solving in humans. For the phenomenon studied by cognitive psychologists under the heading of insight is fundamentally different from that studied in comparative cognition. In light of this impasse, I argue that the reinterpretation of the extant research on animal insight in terms of other high-level cognitive capacities (means-end reasoning in particular) can improve the prospect of a successful comparative research program.

Characterizing Multisystem Barriers to Women's Residential SUD Treatment: A Multisite Qualitative Analysis in Los Angeles.

Residential substance use disorder (SUD) treatment programs are challenged by the differing values of the problem-solving court (PSC) and child welfare (CW) systems, along with communication barriers between staff. This study aimed to understand, from the viewpoints of SUD treatment providers, how divergent values and communication barriers adversely affect women's residential SUD treatment. We conducted qualitative semistructured interviews with 18 SUD treatment clinicians and six directors from four women's residential SUD treatment programs. Using a thematic analysis framework, we identified salient themes across specified codes. Analysis revealed six main themes, suggesting differing values and communication barriers across the SUD, PSC, and CW systems adversely affect the provision of SUD treatment. For differing values, three main themes emerged: (a) unaddressed trauma and fear of mental health treatment seeking; (b) perceptions of mothers with a SUD; and (c) the Adoption and Safe Families Act (ASFA) timeline as a barrier to SUD treatment provision. For communication barriers, three themes emerged: (a) inadequate communication and responsiveness with PSC and CW systems adversely affect treatment coordination, induce patient stress, and treatment disengagement; (b) lack of PSC and CW communication regarding child visitation planning adversely affects treatment motivation and retention; and (c) competing ASFA, PSC, and CW priorities and inadequate cross-system communication adversely affect treatment planning. Treatment providers face significant barriers in providing effective treatment to women simultaneously involved in the CW and PSC systems. Aligning values and addressing communication barriers, changes in policy, and enhanced cross-system training are crucial. Additionally, it is essential to reevaluate the ASFA timeline to align with the long-term treatment needs of mothers with a SUD. Further research should explore the viewpoints of patients, CW, and PSC staff to gain deeper insights into these SUD treatment barriers.

The involvement of decomposition and composition processes in restructuring during problem solving.

Decomposition of chunks has been widely accepted as a critical proxy of restructuring, but the role of composition in forming new representations has been largely neglected. This study aims to investigate the roles of both decomposition and composition processes in chunk restructuring, as well as their relationships with "aha" experiences during problem-solving. Participants were asked to move a part of a character to another character to create two new characters. Across three experiments, the characters to be decomposed or composed were varied in terms of tight or loose chunks. The results showed that decomposition or composition of tight chunks led to lower success rates, longer response times, and significantly stronger "Aha!" emotional experiences (mainly in terms of surprise and suddenness). This study provides evidence for the contribution of both decomposition and composition processes to restructuring in creative insight.

Darwin's agential materials: evolutionary implications of multiscale competency in developmental biology.

A critical aspect of evolution is the layer of developmental physiology that operates between the genotype and the anatomical phenotype. While much work has addressed the evolution of developmental mechanisms and the evolvability of specific genetic architectures with emergent complexity, one aspect has not been sufficiently explored: the implications of morphogenetic problem-solving competencies for the evolutionary process itself. The cells that evolution works with are not passive components: rather, they have numerous capabilities for behavior because they derive from ancestral unicellular organisms with rich repertoires. In multicellular organisms, these capabilities must be tamed, and can be exploited, by the evolutionary process. Specifically, biological structures have a multiscale competency architecture where cells, tissues, and organs exhibit regulative plasticity-the ability to adjust to perturbations such as external injury or internal modifications and still accomplish specific adaptive tasks across metabolic, transcriptional, physiological, and anatomical problem spaces. Here, I review examples illustrating how physiological circuits guiding cellular collective behavior impart computational properties to the agential material that serves as substrate for the evolutionary process. I then explore the ways in which the collective intelligence of cells during morphogenesis affect evolution, providing a new perspective on the evolutionary search process. This key feature of the physiological software of life helps explain the remarkable speed and robustness of biological evolution, and sheds new light on the relationship between genomes and functional anatomical phenotypes.

Object play and problem solving in infancy: Insights into tool use.

Tool use is primarily, but not exclusively, present in species with otherwise advanced cognitive traits. However, the interaction between such traits and conspecific inter-individual variation in the presence, complexity, or intensity of tool use is far from being established. We addressed this matter among human infants, seeking factors that relate to differences in tool use. We examined, both correlationally and experimentally, whether the propensity to engage in object combinations predicts performance in means-end problem-solving tasks involving or not involving the use of a tool. We tested 71 infants aged 15, 18, 21, and 24 months, dividing them into two subgroups: one exposed to an adult demonstrating object-object combinations (i.e., "prompting" infants to combine objects together) and another with comparable social exposure but where the adult demonstrated single-object manipulations. We found a correlation between the combined level of spontaneous and prompted object combinations and problem-solving performance regardless of the involvement of tools in the problem. However, we did not find differences in tool-use performance between the two demonstration subgroups. The correlational analysis suggests that complexity of play, as measured by the frequency of combining objects, is linked to infants' problem-solving skills rather than being specifically associated with tool use, as previously suggested in the literature.

Executive functions and problem-solving-The contribution of inhibition, working memory, and cognitive flexibility to science problem-solving performance in elementary school students.

Previous research has shown that executive functions can contribute to successful problem-solving in preschool and elementary school children. However, most studies did not simultaneously assess the role of different specific aspects of executive functions. Therefore, the aim of our study was to investigate the individual contribution of inhibition, working memory, and cognitive flexibility to science problem-solving performance in elementary school children. A total of 478 children from first and second grades (Mage = 7.44 years) participated in our study. They performed a Go/No-go task (inhibition), a Corsi blocks backward task (working memory), a flexible item selection task (cognitive flexibility), and three science problem-solving tasks, including two gear turning tasks and one stabilization task. Structural equation modeling showed that working memory and cognitive flexibility individually contributed to problem-solving performance, whereas inhibition did not. We conclude that maintaining task requirements and dynamic object relations (working memory) and switching between different problem-solving phases (cognitive flexibility) are essential components of successful science problem-solving in elementary school children. Inhibitory processes may be more relevant in tasks involving a higher degree of interference at the task or response level.

From whole numbers to fractions to word problems: Hierarchical relations in mathematics knowledge for Chinese Grade 6 students.

It is well established in the literature that fraction knowledge is important for learning more advanced mathematics, but the hierarchical relations among whole number arithmetic, fraction knowledge, and mathematics word problem-solving are not well understood. In the current study, Chinese Grade 6 students (N = 1160; 465 girls; Mage = 12.1 years, SD = 0.6) completed whole number arithmetic (addition, subtraction, multiplication, and division), fraction (mapping, equivalence, comparison, and arithmetic), and mathematics word problem-solving assessments. They also completed two control measures: number writing speed and nonverbal intelligence. Structural equation modeling was used to investigate the hierarchical relations among these assessments. Among the four fraction tasks, the correlations were low to moderate, suggesting that each task may tap into a unique aspect of fraction understanding. In the model, whole number arithmetic was directly related to all four fraction tasks, but was only indirectly related to mathematics word problem-solving, through fraction arithmetic. Only fraction arithmetic, the most advanced fraction skill, directly predicted mathematics word problem-solving. These findings are consistent with the view that students need to build these associations into their mathematics hierarchy to advance their mathematical competence.

Co-production and adaptation of a prison-based problem-solving workbook to support the mental health of patients housed within a medium- and low-secure forensic service.

INTRODUCTION: Problem-solving skills (PSS) help to provide a systematic approach to dealing with and managing complex problems. The overall aim of this study was to assess the acceptability and feasibility of developing and adapting a prison-based PSS  workbook for adults within a medium- and low-secure hospital. METHOD: We used the Medical Research Council framework in our participatory mixed methods study incorporating an adapted survey (to identify what types of problems people experience in secure hospitals), a series of three interactive workshops (to co-produce two case study examples for a workbook) and we gathered feedback from patients and hospital staff on the acceptability and feasibility of the workbook. Data from the survey were used to inform the case study examples, and the feedback from patients and hospital staff was descriptively summarised and the results consolidated. RESULTS: In total, 82 (51%) patients took part in the survey; 22 patients and 49 hospital staff provided feedback on the workbook. The survey results indicated that patients regularly experience problems while in the hospital. Patients reported problems relating to restrictions of freedom and boredom. The workshops produced two case studies for the workbooks, with mainly positive patient and staff feedback. More work is required to improve the visual representation of the characters in the case studies, the amount and content of the language and the mechanism of the intervention delivery. CONCLUSION: The adaptation process proved acceptable and feasible to both patients and staff. The co-production methodology for the workbook and feedback from patients and staff was an effective way of iteratively refining the materials to ensure that they were both meaningful and acceptable to staff and patients. Subsequent work is required to develop the workbook and evaluate the feasibility of the intervention delivery, recruitment rates, uptake and adherence to the PSS using a randomised controlled trial. PATIENT OR PUBLIC CONTRIBUTION: At each stage of the project consultation with patients and/or hospital staff was involved.

Can you help me? Using others to offload cognition.

One of the most ancient and widely used forms of cognitive offloading is the outsourcing of cognitive operations onto other humans. Here, we explore whether humans preferentially seek out and use information from more competent compared with less competent others in an ongoing cognitive task. Participants (N = 120) completed a novel computerised visuospatial working memory task where each trial required them to remember either one, five, or ten target locations and recall them after a brief delay. Next, participants watched two virtual people compete in a distinct memory game, where one performed relatively well, demonstrating a stronger memory, and the other performed relatively poorly, demonstrating a weaker memory. Finally, participants completed the initial memory task again, but this time, either the strong-memory person or the weak-memory person was available to help with recall on each trial. Our results showed that, through observation and without direct instruction, participants acquired beliefs about the virtual people's cognitive proficiencies and could readily draw upon these beliefs to inform offloading decisions. Participants were typically more likely to ask for help from the strong-memory person, and this tendency was independent from other factors known to drive cognitive offloading more generally, like task difficulty, unaided cognitive ability, and metacognitive confidence.

Uncovering the interplay between drawings, mental representations, and arithmetic problem-solving strategies in children and adults.

There is an ongoing debate in the scientific community regarding the nature and role of the mental representations involved in solving arithmetic word problems. In this study, we took a closer look at the interplay between mental representations, drawing production, and strategy choice. We used dual-strategy isomorphic word problems sharing the same mathematical structure, but differing in the entities they mentioned in their problem statement. Due to the non-mathematical knowledge attached to these entities, some problems were believed to lead to a specific (cardinal) encoding compatible with one solving strategy, whereas other problems were thought to foster a different (ordinal) encoding compatible with the other solving strategy. We asked 59 children and 52 adults to solve 12 of those arithmetic word problems and to make a diagram of each problem. We hypothesized that the diagrams of both groups would display prototypical features indicating either a cardinal representation or an ordinal representation, depending on the entities mentioned in the problem statement. Joint analysis of the drawing task and the problem-solving task showed that the cardinal and ordinal features of the diagrams are linked with the hypothesized semantic properties of the problems and, crucially, with the choice of one solving strategy over another. We showed that regardless of their experience, participants' strategy use depends on their problem representation, which is influenced by the non-mathematical information in the problem statement, as revealed in their diagrams. We discuss the relevance of drawing tasks for investigating mental representations and fostering mathematical development in school.

Effect of cognitive load and working memory capacity on the efficiency of discovering better alternatives: A survival analysis.

Why do humans attempt to discover better alternatives to solve a problem even when they know the way to solve it? This question is related to the flexibility of thinking and is the subject of studies on the Einstellung effect. This study focuses on cognitive load for familiar trained procedure as a factor that influences the discovery of alternatives in Einstellung situations, where the problem can be solved using a trained procedure. Many studies on creative problem solving and strategy selection demonstrate that cognitive load for facilitates the discovery of alternatives. However, findings are inconsistent regarding Einstellung situations. We argue that the reason for such inconsistent results were the use of manipulations such as the double task, which both load on the trained and alternative procedure and the lack of perspective on efficiency in analysis. Therefore, we examine the relationship between cognitive load manipulated by the complexity of the trained procedure and time-based performance measured by the number of trials prior to finding alternatives. The results illustrate that higher cognitive load increased the efficiency of discovery of alternatives and that this effect was significant for participants with high working memory capacity. This study provides empirical evidence that high cognitive load for trained procedure facilitates the discovery of alternatives and suggests the importance of considering temporal properties, such as efficiency, when examining the effects of working memory on problem solving, which requires cognitive flexibility.

An experimental approach: Investigating the directive function of autobiographical memory.

Why do we have autobiographical memory and how is it useful? Researchers have proposed a directive function; our experiences guide our behavior, particularly when faced with an open-ended problem. Two experiments (one between-participant and one mixed design) were therefore conducted to test whether success autobiographical memories - any experience when the participant felt successful and competent - are helpful for generating solutions to problem scenarios. One research aim was to experimentally test the directive function as current experimental evidence is limited and results are mixed. Consequently, it is unclear if and how autobiographical memory is helpful for open-ended problem solving. Another aim was to test whether self-efficacy is an important factor that supports open-ended problem solving and thus the directive function. Although success memories enhanced self-ratings of self-efficacy across both experiments, in samples of undergraduate students there was no experimental effect of success autobiographical memories on problem solving. Instead, some participants across the memory and control conditions in both experiments, even when not instructed, recalled autobiographical memories related to the problem scenarios presented in the problem-solving task, and these participants did better at problem solving than those who did not. This may hint to a directive function and is perhaps one reason why there is no experimental effect. Sample and experimental design differences are discussed as potential factors that may contribute to non-significant effects in this study but significant effects in others. Our results highlight the complexity of the directive function, and the difficulty of experimentally testing how autobiographical memory directs behavior.

Retrieval fluency inflates perceived preparation for difficult problems.

When faced with a difficult problem, people often rely on past experiences. While remembering clearly helps us reach solutions, can retrieval also lead to misperceptions of our abilities? In three experiments, participants encountered "worst case scenarios" they likely had never experienced and that would be difficult to navigate without extensive training (e.g., bitten by snake). Learning brief tips improved problem-solving performance later, but retrieval increased feelings of preparation by an even larger margin. This gap occurred regardless of whether people thought that tips came from an expert or another participant in the study, and it did not reflect mere familiarity with the problems themselves. Instead, our results suggest that the ease experienced while remembering, or retrieval fluency, inflated feelings of preparation.

Task complexity moderates group synergy.

Complexity-defined in terms of the number of components and the nature of the interdependencies between them-is clearly a relevant feature of all tasks that groups perform. Yet the role that task complexity plays in determining group performance remains poorly understood, in part because no clear language exists to express complexity in a way that allows for straightforward comparisons across tasks. Here we avoid this analytical difficulty by identifying a class of tasks for which complexity can be varied systematically while keeping all other elements of the task unchanged. We then test the effects of task complexity in a preregistered two-phase experiment in which 1,200 individuals were evaluated on a series of tasks of varying complexity (phase 1) and then randomly assigned to solve similar tasks either in interacting groups or as independent individuals (phase 2). We find that interacting groups are as fast as the fastest individual and more efficient than the most efficient individual for complex tasks but not for simpler ones. Leveraging our highly granular digital data, we define and precisely measure group process losses and synergistic gains and show that the balance between the two switches signs at intermediate values of task complexity. Finally, we find that interacting groups generate more solutions more rapidly and explore the solution space more broadly than independent problem solvers, finding higher-quality solutions than all but the highest-scoring individuals.

Managing mental health in chronic care in general practice: a feasibility study of the Healthy Mind intervention.

BACKGROUND AND OBJECTIVE: Mental health issues are common among patients with chronic physical conditions. This study aims to evaluate the feasibility of the Healthy Mind intervention, a general practice-based programme that provides problem-solving therapy (PST) to patients with poor mental well-being and type 2 diabetes (T2D) and/or ischaemic heart disease (IHD). DESIGN AND SETTING: A one-arm feasibility study was conducted in three general practices in the Central Denmark Region. INTERVENTION: Eight healthcare providers from the included general practices underwent a two-day course to acquire PST skills. Screening for poor mental health was carried out at the annual chronic care consultation for T2D or IHD, and PST sessions were offered to patients on indication of poor mental health. Nine patients received PST. METHODS: Semi-structured interviews with eight healthcare providers and six patients were conducted. Data were analysed deductively focusing on appropriateness, acceptability and fidelity of the intervention. RESULTS: The intervention was considered appropriate for the patient group and the general practice setting. The providers acknowledged PST as a valuable tool for managing psychological issues in general practice, and the patients perceived PST as an effective and tangible treatment. Since practice nurses' schedules were generally better suited for longer consultations, they were often the preferred intervention providers. The intervention was largely delivered as intended. However, the GPs generally expected patients to prefer a more directive approach, which sometimes challenged their role as facilitator and guide. CONCLUSION: The Healthy Mind intervention was found to be feasible, and the results support proceeding to a full-scale evaluation trial.

Patients with type 2 diabetes and/or ischaemic heart disease often experience poor mental well-being, revealing a shortage of general practice-based interventions targeting this issue.This study evaluates the feasibility of a problem-solving therapy intervention in general practice for patients with poor mental health and type 2 diabetes and/or chronic ischemic heart disease.Both patients and healthcare providers regarded problem-solving therapy as an acceptable intervention for managing psychological issues in general practice.Healthcare providers preferred practice nurses as the providers of problem-solving therapy since their schedules were often more suitable for longer consultations.In problem-solving therapy, the provider is expected to take a facilitating and guiding role, but GPs sometimes struggled remaining in this role due to a preconceived anticipation that patients expected them to take a more directive approach.

Relationship Between Prone Skills and Motor-Based Problem-Solving Abilities in Full-Term and Preterm Infants During the First 6 Months of Life.

Motor experiences shape cognitive development in infancy, with the prone position being one such crucial motor experience in the first 6 months of life. Although the motor benefits of the prone position are well-documented, its influence on early cognitive abilities remains insufficiently explored. This study quantified the relationship between prone motor skills and motor-based problem-solving abilities in 48 full-term and preterm infants aged 3-6 months. Prone skills were assessed using the Alberta Infant Motor Scale's prone domain. The Assessment of Problem-Solving in Play was utilized to measure motor-based problem-solving by observing how motor actions were used to solve toys. Advanced prone motor skills were correlated with an increase in sophisticated exploration skills and a concurrent decline in lower order exploration skills in all infants, with correlations being stronger in preterm infants. Notably, a 1-point increase in prone skills was associated with a 1.3-point increase in total motor-based problem-solving abilities in all infants. Our findings provide preliminary evidence for the contribution of prone play to cognitive development in infants, prompting considerations for assessment and intervention strategies. Further research is needed to ascertain if the delayed acquisition of prone motor skills is indicative of poor early problem-solving abilities in preterm infants.
