A Comparative Study of Physical and Haptic Exhibits in an Informal Learning Environment.

Virtual exhibits with haptic feedback offer greater flexibility in diversifying content and providing digital affordance, even at a lower cost, than physical exhibits. However, few studies addressed the value of such haptics-enabled educational systems in informal learning environments. In this study, we investigated the feasibility of a haptic exhibit as an alternative or supplement for a traditional physical exhibit in a science museum. We developed a two-degree-of-freedom cable-driven haptic device to simulate physical interactions on a large visual display. Choosing a seesaw-like physical exhibit available in a local museum, we designed and implemented a virtual lever simulation closely embodying the physics principles that the physical exhibit showcased. Then, we conducted an observational user study with children to compare the exhibit-visitor interaction behaviors, learning effects, and self-reported motivation and enjoyment between the physical and virtual exhibits. The results revealed that the visitors well-received and engaged with the haptic exhibit, instantiating its potential application in diverse learning settings. We hope that our research encourages further exploration of innovative haptic exhibits that enhance users' learning experiences across various environments.

Managers and lifelong learning

Lifelong learning has become imperative in today’s rapidly changing world, where people must constantly improve their knowledge and skills to contribute to life and work fully. Since the success of an organization in a knowledge-based economy is highly dependent on competent and committed employees, their professional development should be encouraged and supported at all levels. Managers need to participate in lifelong learning activities. Considering that the willingness to learn is an essential prerequisite for learner engagement and success, this study investigated managers’ motivation for lifelong learning. An online survey was conducted among Croatian managers to answer the research questions. They generally rated their motivation to participate in lifelong learning as very high. According to the results, the studied groups of managers were quite similar in their self-reported motivation levels, except for educational background. The study also found several important motivators for lifelong learning, such as increasing knowledge and skills, improving job performance, and satisfying the need to stay current. Some other potential motivators were not considered important, including gaining social recognition and job insecurity. An exploratory factor analysis revealed three underlying dimensions of motivation: job satisfaction and compensation, competence development, and recognition and respect. In addition, some significant group differences in the factors were found. Given the limited literature on this topic, this study contributes to a better understanding managers’ motivation for lifelong learning.

Effort Foraging Task reveals positive correlation between individual differences in the cost of cognitive and physical effort in humans

Effort-based decisions, in which people weigh potential future rewards against effort costs required to achieve those rewards involve both cognitive and physical effort, though the mechanistic relationship between them is not yet understood. Here, we use an individual differences approach to isolate and measure the computational processes underlying effort-based decisions and test the association between cognitive and physical domains. Patch foraging is an ecologically valid reward rate maximization problem with well-developed theoretical tools. We developed the Effort Foraging Task, which embedded cognitive or physical effort into patch foraging, to quantify the cost of both cognitive and physical effort indirectly, by their effects on foraging choices. Participants chose between harvesting a depleting patch, or traveling to a new patch that was costly in time and effort. Participants’ exit thresholds (reflecting the reward they expected to receive by harvesting when they chose to travel to a new patch) were sensitive to cognitive and physical effort demands, allowing us to quantify the perceived effort cost in monetary terms. The indirect sequential choice style revealed effort-seeking behavior in a minority of participants (preferring high over low effort) that has apparently been missed by many previous approaches. Individual differences in cognitive and physical effort costs were positively correlated, suggesting that these are perceived and processed in common. We used canonical correlation analysis to probe the relationship of task measures to self-reported affect and motivation, and found correlations of cognitive effort with anxiety, cognitive function, behavioral activation, and self-efficacy, but no similar correlations with physical effort.

43 Mood and Everyday Function in Older Adults: Analyses of Self-report and Performance-based Measures of Everyday Function

Objective:The relation between depressed mood and functional difficulties in older adults has been demonstrated in studies using self-report measures and has been interpreted as evidence for low mood negatively impacting everyday functional abilities. However, few studies have directly examined the relation between mood and everyday function using performance-based tests. This study included a standardized, performance-based measure of everyday action (Naturalistic Action Task, NAT) to test the prediction that report of depression symptoms are associated with self-report and performance-based tests of everyday function. Associations with anxiety symptoms and motivation/grit and everyday function also were explored.Participants and Methods:68 older adults without dementia were screened and recruited (n = 55, M age = 74.21, SD= 6.80, age range = 65 to 98) from the community and completed self-report measures of depression symptoms (GDS), anxiety (GAI), motivation (Short Grit-S), and everyday functioning (FAQ). Participants also performed the NAT, which requires completion of a breakfast and lunch task and is scored for task accomplishment, errors (micro-errors, overt, motor), and total time. Additionally, an informant also reported on the participant’s everyday function. Spearman correlations were performed and results showing a medium effect size or greater are reported.Results:Participant mood (GDS) was associated with self-reported function (FAQ; r =.45) but not performance-based measures of everyday function (NAT). Self-reported anxiety and motivation were not meaningfully associated with either self-reported or performance-based everyday function. Participant self-report (FAQ) and informant report of participant’s function (IFAQ) supported the validity of performance-based assessment as both were meaningfully associated with NAT performance (FAQ x NAT overt errors r = .34; I-FAQ x NAT micro-errors r = .34; I-FAQ x NAT motor errors r = .49).Conclusions:Mood, but not anxiety or motivation, was associated with self-reported everyday function but not performance-based function. When considered alongside the meaningful relations between self/informant-report of function and everyday task performance, results suggest mood does not impact everyday function abilities in community-dwelling older adults without dementia. We suggest that frameworks to be reconceptualized to consider the potential for mild functional difficulties to negatively impact mood in older adults without dementia. Additionally, interventions and compensatory strategies designed to improve everyday function should examine the impact on mood outcomes.

How to “inoculate” against multimodal misinformation: A conceptual replication of Roozenbeek and van der Linden (2020)

Building misinformation resilience at scale continues to pose a challenge. Gamified “inoculation” interventions have shown promise in improving people’s ability to recognize manipulation techniques commonly used in misinformation, but so far few interventions exist that tackle multimodal misinformation (e.g., videos, images). We developed a game called Cat Park, in which players learn about five manipulation techniques (trolling, emotional manipulation, amplification, polarization, and conspiracism), and how misinformation can spread through images. To test the game’s efficacy, we conducted a conceptual replication (N = 380) of Roozenbeek and van der Linden’s 2020 study about Harmony Square, with the same study design, item set, and hypotheses. Like the original study, we find that people who play Cat Park find misinformation significantly less reliable post-gameplay (d = 0.95, p < 0.001) compared to a control group, and are significantly less willing to share misinformation with people in their network (d = 0.54, p < 0.001). These effects are robust across different covariates. However, unlike the original study, Cat Park players do not become significantly more confident in their ability to identify misinformation (p = 0.204, d = − 0.13). We did not find that the game increases people’s self-reported motivation and confidence to counter misinformation online.

P104 The Impact of Total Sleep Deprivation on Performance in the Esport ‘Rocket League’.

Abstract Preliminary findings from this study were presented as a poster (P376) at Sleep Europe 2022 (https://doi.org/10.1111/jsr.13740). Introduction Sleep loss is presumed by academics and esport (organised competitive video-game play) athletes to be an in-game esport performance hindrance, primarily due to its well understood effects on multiple domains of cognitive performance. However, the effects of acute sleep loss specifically on esports performance have not been explored. We aimed to elucidate whether total sleep deprivation degrades in-game performance in the popular esport ‘Rocket League’. Methods Forty habitual Rocket League players were paired according to in-game ability level (twenty pairs), with one assigned to a control group (CON) and the other assigned to an intervention group (TSD). Two test sessions took place, in which paired players completed subjective and cognitive performance measures, and played seven Rocket League matches against one another. In one session, both players in a pair were well rested, while in the other, CON was rested while TSD was sleep deprived. Results Acute total sleep deprivation resulted in higher self-reported sleepiness, lower alertness and motivation, poorer performance on the Psychomotor Vigilance Task (PVT) and two-choice component of the Category Switch Task (CST). Despite this, overall in-game esport performance did not worsen due to sleep deprivation, although exploratory analysis suggests potential in-game strategy change. Discussion Our findings do not suggest that sleep loss is inconsequential for esport athletes, but rather suggest that acute bouts of sleep loss of similar/lesser severity may not be a primary concern for in-game esports performance.

Motivation-related influences on fNIRS signals during walking exercise: a permutation entropy approach.

Cortical activity is typically indexed by analyzing functional near-infrared spectroscopy (fNIRS) signals in terms of the mean (e.g., mean oxygenated hemoglobin; HbO). Entropy approaches have been proposed as useful complementary methods for analyzing fNIRS signals. Entropy methods consider the regularity of a time series, and in doing so, may provide additional insights into the underlying dynamics of brain activity. Recent research using fNIRS found that non-disabled adults exhibit widespread increases in cortical activity and walk faster when under "extra motivation" conditions (e.g., verbal encouragement, lap timer) compared to trials without such motivators ("standard motivation"). This ancillary analysis of that study aimed to assess the extent to which fNIRS permutation entropy (PE) was affected by motivational conditions and explained variance in self-reported motivation. No regional PE differences were found between different motivational conditions. However, a greater difference in PE between motivational conditions (higher in standard, lower in extra motivation) in the anterior prefrontal cortex (aPFC) was associated with greater self-determined motivation. PE was also higher (less regular) in the primary sensorimotor cortex lower limb area compared to all other cortical areas analyzed, except the dorsal premotor cortex, regardless of motivational condition. This study provides early evidence to suggest that while different motivational environments during walking activity influence the magnitude of fNIRS signals, they may not influence the regularity of cortical signals. However, the magnitude of PE difference between motivational conditions was related to self-determined motivation in the aPFC, and this is an area warranting further investigation.

Teacher perceptions of student motivation and engagement: longitudinal associations with student outcomes

AbstractStudies have shown that teacher perceptions of student achievement influence teacher-student interactions, subsequently affecting student outcomes. However, teachers may also take note of and respond to the motivation and engagement of their students in a differential way, which could affect student outcomes as well. In the present study, we thus examined whether teacher perceptions of student motivation and engagement predict student achievement and self-reported motivation and engagement in reading and maths over several school years. Analysing longitudinal data from N = 2402 students and their teachers, we found that teacher perceptions of student motivation and engagement in Grade 5 were significantly related to student achievement in reading 1 year later and in maths 1, 2, and 3 years later. An association with student motivation and engagement was only found for maths 1 year later.

Students' motivation and engagement in the learning process of literature teaching using imaginative re-creation technique

This article investigates the influence of imaginative re-creation techniques on students' motivation and engagement within the context of literature teaching. Traditional pedagogical methods often struggle to maintain high student involvement in literature classes. This single-case research employed a mixed-methods approach combining observation and questionnaire data to assess students' motivation and engagement. A total of forty-five participants were involved in the study. Quantitative analysis of the questionnaires revealed an average level of motivation and engagement. However, a qualitative analysis of observations demonstrated that students exhibit a heightened sense of enthusiasm and engagement during class sessions that incorporate imaginative re-creation techniques. The findings suggest that while questionnaire responses might not fully capture the extent of students' enthusiasm, the classroom atmosphere is positively affected by the implementation of imaginative re-creation techniques. This implies that students' active participation and emotional connection with the literature are better reflected in their in-class behaviors than in self-reported questionnaire responses. In conclusion, this article highlights the complex relationship between students' self-reported motivation and engagement and their observable behavior during literature classes incorporating imaginative re-creation techniques. It underscores the need for a comprehensive assessment considering quantitative and qualitative data to understand students' educational experiences better. By integrating imaginative re-creation techniques into literature teaching, educators can foster a dynamic and engaging learning environment that goes beyond average questionnaire results and cultivates a genuine passion for literary exploration among students.

Impacting Children’s Physical and Mental Health through Kinesiology Support in Clinical Care: A Randomized Controlled Trial Protocol

Objectives: To enhance the confidence of children and adolescents with medical conditions and disabilities to engage in healthy, active lifestyles. Children with medical conditions and disabilities often exhibit more sedentary lifestyles relative to peers and are at increased risk of poor health outcomes. Clinical experience suggests physical activity confidence is an important factor influencing physical activity participation.Methods: This randomized controlled trial evaluates an evidence-based intervention targeting physical activity confidence among children and adolescents with medical conditions and disabilities. Potential participants, 8 to 18 years of age diagnosed with a medical condition or disability, will be screened for adequate physical activity motivation but a lack confidence. Consenting participants (n=128) will be randomized 1:1 to a 12-week in-person or virtual physical activity intervention (24 hours/week total) led by a Registered Kinesiologist or control (assessments only). The intervention will combine physical activity participation with education about physical activity knowledge, goal setting, motivation and self-management. Primary outcomes are self-reported physical activity confidence and motivation at baseline, post-intervention and three months following intervention completion. A secondary outcome will be daily physical activity minutes assessed by accelerometry. A repeated measures mixed model will be used to compare outcomes between the in-person intervention, virtual intervention, and control groups (alpha=0.05).Conclusions: This trial aims to assess the impact of a novel application of behaviour change theory on physical activity confidence among children and adolescents living with medical conditions or disabilities. Increased physical activity confidence, knowledge and skills could enable these youth to lead a more active lifestyle.

There is a party in my head and no one is invited: Resting-state electrocortical activity and solitude.

What are the motivational underpinnings of solitude? We know from self-report studies that increases in solitude are associated with drops in approach motivation and rises in avoidance motivation, but only when solitude is experienced as non-self-determined (i.e., non-autonomous). However, the extent to which individual differences in solitude relate to neurophysiological markers of approach-avoidance motivation derived from resting-state electroencephalogram (EEG) is unknown. These markers are Frontal Alpha Asymmetry, beta suppression, and midline Posterior versus Frontal EEG Theta Activity. We assessed the relation among individual differences in the reasons for solitude (i.e., preference for solitude, motivation for solitude), approach-avoidance motivation, and resting-state EEG markers of approach-avoidance motivation (N = 115). General preference for solitude was negatively related to approach motivation, observed in both self-reported measures and EEG markers of approach motivation. Self-determined solitude was positively related to both self-reported approach motivation and avoidance motivation in the social domain (i.e., friendship). Non-self-determined solitude was negatively associated with self-reported avoidance motivation. This research was a preliminary attempt to address the neurophysiological underpinnings of solitude in the context of motivation.

Comparison of placenta consumers’ and non-consumers’ postpartum depression screening results using EPDS in US community birth settings (n=6038): a propensity score analysis

BackgroundPreventing postpartum depression (PPD) is the most common self-reported motivation for human maternal placentophagy, yet very little systematic research has assessed mental health following placenta consumption. Our aim was to compare PPD screening scores of placenta consumers and non-consumers in a community birth setting, using propensity score matching to address anticipated extensive confounding.MethodsWe used a medical records-based data set (n = 6038) containing pregnancy, birth, and postpartum information for US women who planned and completed community births. We first compared PPD screening scores as measured by the Edinburgh Postpartum Depression Scale (EPDS) of individuals who consumed their placenta to those who did not, with regard to demographics, pregnancy characteristics, and history of mental health challenges. Matching placentophagic (n = 1876) and non-placentophagic (n = 1876) groups were then created using propensity scores. The propensity score model included more than 90 variables describing medical and obstetric history, demographics, pregnancy characteristics, and intrapartum and postpartum complications, thus addressing confounding by all of these variables. We then used logistic regression to compare placentophagic to non-placentophagic groups based on commonly-cited EPDS cutoff values (≥ 11; ≥ 13) for likely PPD.ResultsIn the unmatched and unadjusted analysis, placentophagy was associated with an increased risk of PPD. In the matched sample, 9.9% of women who ate their placentas reported EPDS ≥ 11, compared to 8.4% of women who did not (5.5% and 4.8%, respectively, EPDS ≥ 13 or greater). After controlling for over 90 variables (including prior mental health challenges) in the matched and adjusted analysis, placentophagy was associated with an increased risk of PPD between 15 and 20%, depending on the published EPDS cutoff point used. Numerous sensitivity analyses did not alter this general finding.ConclusionsPlacentophagic individuals in our study scored higher on an EPDS screening than carefully matched non-placentophagic controls. Why placentophagic women score higher on the EPDS remains unclear, but we suspect reverse causality plays an important role. Future research could assess psychosocial factors that may motivate some individuals to engage in placentophagy, and that may also indicate greater risk of PPD.

Neurofeedback therapy to improve cognitive function in patients with chronic post-stroke attention deficits: a within-subjects comparison.

We investigated a slow-cortical potential (SCP) neurofeedback therapy approach for rehabilitating chronic attention deficits after stroke. This study is the first attempt to train patients who survived stroke with SCP neurofeedback therapy. We included N = 5 participants in a within-subjects follow-up design. We assessed neuropsychological and psychological performance at baseline (4 weeks before study onset), before study onset, after neurofeedback training, and at 3 months follow-up. Participants underwent 20 sessions of SCP neurofeedback training. Participants learned to regulate SCPs toward negativity, and we found indications for improved attention after the SCP neurofeedback therapy in some participants. Quality of life improved throughout the study according to engagement in activities of daily living. The self-reported motivation was related to mean SCP activation in two participants. We would like to bring attention to the potential of SCP neurofeedback therapy as a new rehabilitation method for treating post-stroke cognitive deficits. Studies with larger samples are warranted to corroborate the results.

Examining Motivation of First-Year Undergraduate Anatomy Students Through the Lens of Universal Design for Learning (UDL): A Single Institution Study

Motivation is critical for meaningful learning among healthcare students studying anatomy. Learners are highly variable, and it is important to ensure learners are equally supported in the diverse aspects of an anatomy curriculum. The implementation of the educational framework, Universal Design for Learning (UDL), in anatomy curricula could potentially enhance student motivation. The multiple means of engagement principle of UDL refers to the enhancement of motivation among students. This study aimed to identify healthcare students’ motivation levels at the start and end of their anatomy module and whether there was any change in motivation. The Motivated Strategies for Learning Questionnaire (MSLQ) was distributed to gather the self-reported motivation levels of first-year undergraduate medical, dental and occupational therapy (OT) and speech and language therapy (SLT) students studying anatomy at the start of their respective anatomy modules and again at the end of the module. The overall response rate was 74% and 69%, at the start and end of the study, respectively. Responses were analysed by the respective programme of study. Motivation to study anatomy among medical, dental, OT and SLT students ranged from medium to high on the MSLQ at the start of their respective anatomy modules. By the end of the anatomy modules, dental students reported high levels of motivation to study anatomy, whereas motivation among medical, OT and SLT students ranged from medium to high. A change in students’ self-reported motivation levels while studying anatomy was identified. The study emphasises the benefits of UDL and its flexible nature to enhance motivation.

Detected Affect During Online Mathematics Learning Mediate Self-Report Motivation Changes: Examining a Motivation-Affect Regulation Model

This study investigates relationships between detected affect during online learning and self-reports concerning motivational constructs in mathematics. Students reported their self-concept, interest, and values in mathematics before and after learning mathematics on an online intelligent tutoring system for one academic year over the autumn and spring semesters. Students’ experiences of engaged concentration, confusion, frustration, and boredom were detected using log files from the system. The participants included over 8,000 2nd- to 8th-grade students in the United States who used an intelligent tutoring system, Reasoning Mind, during the academic year of 2017-2018. Path analyses with mediating effects indicate that students initially perceiving high self-concept are less frustrated in both autumn and spring. Students interested in mathematics experience initial disengagement and later confusion in online mathematical problem-solving. This result calls for cross-platform support from teachers and system designs, especially for students interested in traditional mathematical teaching and learning. For theory, this study posits the Motivation-Affect Regulation (MAR) model, highlighting the mediating effects of motivation effect. Results find that the earlier self-concept can be mediated by fewer frustrations in online learning and lead to later self-concept. Interest triggers early disengagement and late confusion during online learning. Value is not mediated by affect. In methodology, structural equation modelling with mediating models offers opportunities to investigate more complex relationships when common measures are collected across time. Both offline pedagogical designs and online learning system designs need to consider the gaps between different formats of learning. Students with a high interest in learning mathematics in real classrooms may fail to adjust themselves easily to online mathematical problem-solving and experience disengagement in the early stages (one semester) and confusion in the stages (after one semester).

The L2 Motivational Self System and L2 Achievement: A Study of DNTU's Students

The study detailed in this article investigates the connection between the L2 competency level of Vietnamese English as a Foreign Language (EFL) learners and Dörnyei's (2005, 2009) Second Language Motivational Self System (L2MSS). Descriptive and inferential analyses of the collected data revealed expected—that the components of the L2MSS were a good predictor of the learners’ intended learning efforts. However, the study also established that in this learner population, these components were not consistently correlated with L2 achievement. The findings can be treated as evidence that self-reported motivation does not always have behavioral consequences.

Patterns and predictors of adherence to follow-up health guidance invitations in a general health check-up program in Japan: A cohort study with an employer-sponsored insurer database.

Japan has conducted a nationwide annual health check-up program since 2008, focusing on metabolic syndrome and subsequent health guidance in individuals at high risk for cardiovascular disease. However, the adherence rate to health guidance invitations was assumed to be low in previous reports. Therefore, this study aimed to characterize adherence patterns in the program and identify major predictors of adherence to health guidance invitations. We studied 186,316 adults (aged 40-74 years) who were included in a nationwide employer-sponsored insurer's database in Japan at the beginning of the fiscal year 2017. We first described adherence to health check-ups, the proportion of individuals with high cardiovascular risk, and adherence to health guidance invitations. Predictors of adherence to the invitation were then identified among eligible high-risk individuals. In 2017, 71.7% of the study population (n = 133,573) underwent health check-ups, among whom 23.2% (n = 30,979) were invited for health guidance because of their high cardiovascular risk. Among those individuals, 35.2% (n = 10,614) received health guidance. Predictors of improved adherence to health guidance invitation were older age, more concerning blood pressure or laboratory data results, and self-reported motivation for a lifestyle change. Though 70% of eligible adults attended Japan's annual cardiovascular risk check-ups, only 35% of individuals with high cardiovascular risk adhered to health guidance invitations. Future policy reforms to improve adherence to this program should target younger individuals and those with mild stages of hypertension, diabetes, or dyslipidemia.

Effort-cost decision-making in psychotic and mood disorders.

Avolition and anhedonia are core symptoms across psychosis and mood disorders. One important mechanism thought to relate to these symptoms is effort-cost decision-making (ECDM), the valuation and estimation of work required to obtain a given reward. While recent work suggests impairments in ECDM in both mood disorders and psychosis relative to controls, limited work has taken a transdiagnostic approach to examine how these deficits relate to different symptom profiles across disorders. The present study investigated ECDM across schizophrenia/schizoaffective disorder (N = 33), bipolar disorder (N = 47), unipolar depression (N = 61), and healthy controls (N = 58) to examine willingness to expend physical effort. Moreover, we examined the relationship between ECDM and motivation and pleasure symptoms across participants. We found that people with schizophrenia and bipolar disorder showed a reduced willingness to expend physical effort at high reward values relative to controls, while as a group, those with depression showed no differences relative to controls. However, individual differences in self-reported motivation and pleasure predicted reduced ECDM, particularly at high reward values, suggesting that both severity of symptoms and diagnostic categories are important for understanding altered ECDM in psychopathology.

Investigating the effects of autonomy-supportive parenting practices on Italian young adolescent students' motivation to defend victims of bullying: findings on the mediating roles of reactance, depression, anxiety, and stress.

Data were collected from 578 Italian public school students ages 10-14 (M age = 11.8 years, 52% boys), who completed a survey in their classroom. The survey included self-report measures of parental orientation, motivation to defend victims of bullying, reactance, anxiety, depression, and stress. We found that autonomy-supportive parenting had a positive effect on autonomous motivation to defend, and that this effect was weakly mediated by reactance. Moreover, autonomy-supportive parenting had a negative effect on extrinsic motivation to defend, which was partially mediated by reactance. Reactance had a positive direct effect on extrinsic motivation to defend, but results also showed that anxiety, depression, and stress did not mediate the effect of autonomy-supportive parenting on motivation to defend. Additionally, autonomy-supportive parenting appeared to play a protective role, being associated with lower levels of reactance, anxiety, depression, and stress. Finally, gender differences were found in our sample, with extrinsic motivation to defend being more prevalent in boys, and autonomous motivation to defend being more prevalent in girls. Girls also reported higher levels of anxiety, depression, and stress, compared to boys. Our findings show that autonomy-supportive parenting practices play a significant role in fostering young adolescents' motivation to defend victims of bullying, and that they are also linked with lower feelings of reactance, anxiety, depression, and stress. We argue that interventions aimed at contrasting bullying and cyberbullying among youths should seek to involve parents more and promote the adoption of more autonomy-supportive parenting practices, due to their consistently proven beneficial effects.

Dissociation of Cognitive Effort–Based Decision Making and Its Associations With Symptoms, Cognition, and Everyday Life Function Across Schizophrenia, Bipolar Disorder, and Depression

BackgroundAnhedonia and amotivation are symptoms of many different mental health disorders that are frequently associated with functional disability, but it is not clear whether the same processes contribute to motivational impairments across disorders. This study focused on one possible factor, the willingness to exert cognitive effort, referred to as cognitive effort–cost decision making. MethodsWe examined performance on the deck choice task as a measure of cognitive effort–cost decision making, in which people choose to complete an easy task for a small monetary reward or a harder task for larger rewards, in 5 groups: healthy control (n = 80), schizophrenia/schizoaffective disorder (n = 50), bipolar disorder with psychosis (n = 58), current major depression (n = 60), and past major depression (n = 51). We examined cognitive effort–cost decision making in relation to clinician and self-reported motivation symptoms, working memory and cognitive control performance, and life function measured by ecological momentary assessment and passive sensing. ResultsWe found a significant diagnostic group × reward interaction (F8,588 = 4.37, p < .001, ηp2 = 0.056). Compared with the healthy control group, the schizophrenia/schizoaffective and bipolar disorder groups, but not the current or past major depressive disorder groups, showed a reduced willingness to exert effort at the higher reward values. In the schizophrenia/schizoaffective and bipolar disorder groups, but not the major depressive disorder groups, reduced willingness to exert cognitive effort for higher rewards was associated with greater clinician-rated motivation impairments, worse working memory and cognitive control performance, and less engagement in goal-directed activities measured by ecological momentary assessment. ConclusionsThese findings suggest that the mechanisms contributing to motivational impairments differ among individuals with psychosis spectrum disorders versus depression.
