Beyond monetary value: how reward type drives cheating in a gender-judgment task.

Investigating the effects of monetary incentives on dishonest behavior provides valuable insights into human integrity and ethical decision-making processes. This study is conducted through the lens of self-concept maintenance theory. The aim of this study is to examine the influence of different types of rewards (score-based vs. monetary) and their magnitude on dishonest behavior within a gender judgment task. Using a quantitative experimental design, this study involved 116 participants who were randomly assigned to conditions that differed in reward type (score or money) and magnitude (10 yuan vs. 50 yuan). Dishonest behavior was assessed using a gender judgment task with mechanisms to simulate conditions conducive to planned cheating. Results revealed significant differences in dishonesty rates between score and money conditions, with a higher proportion of dishonest participants observed in the score condition compared to the money condition. The timing of initial cheating was earlier in the score condition compared to the money condition. No significant differences were found in the proportion of dishonest participants, the cheating rate, or the timing of initial cheating across reward levels within either condition. The rate of cheating increased over time, suggesting a temporal dynamic in unethical decision making. The study demonstrates that the nature of rewards significantly influences the likelihood of dishonest behavior, with intangible score-based rewards facilitating rationalizations for dishonesty more readily than tangible financial incentives. These findings enrich the understanding of moral psychology by highlighting the complex interplay between reward types, ethical rationalization, and the dynamics of dishonest behavior.

The Two Sides of Crowdfunding Success: Attributes and Motivations of Backers and Entrepreneurs—Evidence from Israel

Using two studies of the same leading Israeli crowdfunding platform—‘Headstart’—various aspects of the fundraising method discussed in this article were explored. The first study identifies the factors that impact the amount of investment in crowdfunding projects. Using data from 517 backers who invested in ‘Headstart’ projects, direct correlations were established between the age of the backers, the minimum tangible reward levels, being friends or family of the entrepreneurs and the level of risk aversion with the investment amount. It is argued that these results are related to more extensive information being available to family and friends. Furthermore, the findings implicate that for different amounts of investment, different factors will have an impact. The second study seeks to identify the crowdfunding entrepreneurs’ unique characteristics that make some of them succeed in funding their projects more than others. According to the responses of 162 crowdfunding entrepreneurs to the ‘Big Five’ questionnaire, their agreeableness and extraversion have a positive impact on the success of campaign funding, but the impact is gender related. Neuroticism and conscientiousness are also factors. These studies contribute to the literature by using rare, first-hand information from entrepreneurs and backers to identify the internal and external factors that lead to success in crowdfunding.

Internet-delivered approach-avoidance conflict task shows temporal stability and relation to trait anxiety

Excessive avoidance causes functional impairment and maintains anxiety disorders. In the laboratory, approach-avoidance conflict tasks (AACT) can be used to study approach-avoidance behavior in mixed outcome situations (i.e., the same behavior entails both aversive and rewarding consequences). We tested the feasibility of a novel, internet-delivered AACT (iAACT) by conceptually replicating results from laboratory AACTs, including the temporal stability of results and the relation between trait anxiety and approach-avoidance behavior. Individuals from the general population (n = 186) completed a measure of trait anxiety and the iAACT, which entailed choosing either to approach aversive stimuli (image-sound) and receive a reward (points), or to avoid them and not receive a reward (i.e., costly avoidance). The temporal stability of approach-avoidance behavior was assessed by inviting participants to repeat the iAACT six weeks later (n = 91). Consistent with previous findings in laboratory AACTs, results showed that approach behavior to aversive stimuli increased with higher reward levels. These findings were replicated in the follow-up session. Also consistent with previous studies, higher trait anxiety was associated with elevated costly avoidance. In conclusion, the consistency of our results with laboratory studies indicates that the iAACT is feasible and may provide a cost-effective and scalable method to study anxiety-related approach-avoidance behavior remotely.

Reward-dependent Graded Suppression of Sensorimotor Beta-band Local Field Potentials During an Arm Reaching Task in NHP.

A better understanding of reward signaling in the sensorimotor cortices can aid in developing Reinforcement Learning-based Brain-Computer Interfaces (RLBCI) for restoration of movement functions with fewer implants. Brain-computer interfaces (BCIs) using local field potentials (LFPs) have recently achieved performance comparable to spike-BCIs [1]. With superior stability over time, LFPs may be the preferred signal for BCIs. We show that sensorimotor LFPs can provide reward level information (R1 - R3) like spikes[2]. We used a cued reward-level reaching task in which reward information was temporally dissociated from movement information. This allowed the study of reward- and movement-related modulations in LFPs. We recorded simultaneously from contralateral primary -somatosensory (S1), -motor (M1), and the dorsal premotor (PMd) cortices in a female Macaca Mulatta. We found that all three cortices' average beta band (14-30 Hz) amplitude showed robust modulation with reward levels during the cue presentation period. Such modulation was consistently observed after controlling for cue color, differences in behavioral variables, and electromyogram (EMG) activity. Statistical amplitude analysis showed that reward level could be extracted from the simple LFP feature of beta band amplitude, even before a reaching target appeared, and no specific reach plan could be developed. Clinical Relevance - The availability of reward-related signals in the sensorimotor cortical (S1, M1,and PMd) LFPs' prior to movement planning opens new avenues to build RLBCIs with fewer implants recording fewer sites among different cortices Reward and motivational representations derived from LFPs compared to spikes allow the development of long-term clinical applications given LFP's stability and ease of recording over long periods.

The Influencing Factors of Art Graduates' Entrepreneurship by Logistic Regression Analysis From the Perspective of Entrepreneurial Mentality.

The purpose of this study was to understand the influence mechanism of college students’ entrepreneurial intention in view of the increasing number of college students at present to alleviate college students’ employment competition. The psychological factors that influence the entrepreneurial tendency of art graduates were analyzed and studied. First, venture capital and factors affecting entrepreneurial performance were analyzed. Second, the coefficient calculation is carried out for college students majoring in art through the regression analysis of the logistic model. Finally, a team entrepreneurial performance questionnaire was designed, and team reward levels were discussed. The results show that the logistic model can well reflect the real situation of the respondents. The significance level of the entrepreneurial team was 0.02, which was correlated. Additionally, corresponding suggestions were put forward according to the questionnaire results. Clear team goals, assignment of tasks to members, good pressure resistance, and psychological quality of members are necessary qualities for successful entrepreneurship. This conclusion provides a certain theoretical basis for the current college students’ entrepreneurial learning and a reliable inspiration for helping college students to successfully start a business.

Cerebellar and cortico-striatal-midbrain contributions to reward-cognition processes and apathy within the psychosis continuum

Negative symptoms in the psychosis continuum are linked to impairments in reward processing and cognitive function. Processes at the interface of reward processing and cognition and their relation to negative symptoms remain little studied, despite evidence suggestive of integration in mechanisms and neural circuitry. Here, we investigated brain activation during reward-dependent modulation of working memory (WM) and their relationship to negative symptoms in subclinical and early stages of the psychosis continuum. We included 27 persons with high schizotypal personality traits and 23 patients with first episode psychosis as well as 27 healthy controls. Participants underwent functional magnetic resonance imaging while performing an established 2-back WM task with two reward levels (5 CHF vs. no reward), which allowed us to assess common reward-cognition regions through whole-brain conjunction analyses and to investigate relations with clinical scores of negative symptoms. As expected for behavior, reward facilitated performance while cognitive load diminished it. At the neural level, the conjunction of high reward and high cognitive load contrasts across the psychosis continuum showed increased hemodynamic activity in the thalamus and the cerebellar vermis. During high cognitive load, more severe apathy but not diminished expression in the psychosis continuum was associated with reduced activity in right lateral orbitofrontal cortex, midbrain, posterior vermal cerebellum, caudate and lateral parietal cortex. Our results suggest that hypoactivity in the cerebellar vermis and the cortical-striatal-midbrain-circuitry in the psychosis continuum relates to apathy possibly via impaired flexible cognitive resource allocation for effective goal pursuit.

Contribution of the sensorimotor beta oscillations and the cortico-basal ganglia-thalamic circuitry during value-based decision making: A simultaneous EEG-fMRI investigation

In decision neuroscience, the motor system has primarily been considered to be involved in executing choice actions. However, a competing perspective suggests its engagement in the evaluation of options, traditionally considered to be performed by the brain's valuation system. Here, we investigate the role of the motor system in value-based decision making by determining the neural circuitries associated with the sensorimotor beta oscillations previously identified to encode decision options. In a simultaneous EEG-fMRI study, participants evaluated reward and risk associated with a forthcoming action. A significant sensorimotor beta desynchronization was identified prior to and independent of response. The level of beta desynchronization showed evidence of encoding the reward levels. This beta desynchronization covaried, on a trial-by-trial level, with BOLD activity in the cortico-basal ganglia-thalamic circuitry. In contrast, there was only a weak covariation within the valuation network, despite significant modulation of its BOLD activity by reward levels. These results suggest that the way in which decision variables are processed differs in the valuation network and in the cortico-basal ganglia-thalamic circuitry. We propose that sensorimotor beta oscillations indicate incentive motivational drive towards a choice action computed from the decision variables even prior to making a response, and it arises from the cortico-basal ganglia-thalamic circuitry.

Sick Leave and Intention to Quit the Job among Nursing Staff in German Hospitals during the COVID-19 Pandemic.

Background: Sick leave and turnover of nurses exacerbate an already existing nursing shortage during the COVID-19 pandemic in Germany and other countries. Frequency and associated factors of sick leave and intention to quit among nurses need to be examined to maintain healthcare. Methods: An online survey among nursing staff (N = 757) in German hospitals was conducted between May and July 2021. Sick leave days, intention to quit, working conditions, depression, anxiety and sleep disorder symptoms, effort-reward imbalance (ERI), COVID-19-related and sociodemographic variables were measured. Regression analyses were performed. Results: The intention to quit was present in 18.9%. One third (32.5%) reported sick leave of ≥10 and 12.3% more than 25 days in 12 months. Significant predictors for ≥10 sick leave days were infection with SARS-CoV-2, a pre-existing illness, exhaustion, trust in colleagues and fear of becoming infected. Higher ERI reward levels, perception of sufficient staff and contact with infected patients were associated with lower odds for ≥10 sick leave days. Lower reward levels, having changed work departments during the pandemic, working part-time and higher depression levels significantly predicted turnover intention. Conclusion: Alarmingly, many nurses intend to quit working in healthcare. Perceived reward seems to buffer both sick leave and turnover intention. Enhancing protection from COVID-19 and reducing workload might also prevent sick leave. Depression prevention, improved change management and support of part-time workers could contribute to reducing turnover intention among nurses.

Supported Diagnosis of Attention Deficit and Hyperactivity Disorder from EEG Based on Interpretable Kernels for Hidden Markov Models.

As a neurodevelopmental pathology, Attention Deficit Hyperactivity Disorder (ADHD) mainly arises during childhood. Persistent patterns of generalized inattention, impulsivity, or hyperactivity characterize ADHD that may persist into adulthood. The conventional diagnosis relies on clinical observational processes yielding high rates of overdiagnosis due to varying interpretations among specialists or missing information. Although several studies have designed objective behavioral features to overcome such an issue, they lack significance. Despite electroencephalography (EEG) analyses extracting alternative biomarkers using signal processing techniques, the nonlinearity and nonstationarity of EEG signals restrain performance and generalization of hand-crafted features. This work proposes a methodology to support ADHD diagnosis by characterizing EEG signals from hidden Markov models (HMM), classifying subjects based on similarity measures for probability functions, and spatially interpreting the results using graphic embeddings of stochastic dynamic models. The methodology learns a single HMM for EEG signal from each patient, so favoring the inter-subject variability. Then, the Probability Product Kernel, specifically developed for assessing the similarity between HMMs, fed a support vector machine that classifies subjects according to their stochastic dynamics. Lastly, the kernel variant of Principal Component Analysis provided a means to visualize the EEG transitions in a two-dimensional space, evidencing dynamic differences between ADHD and Healthy Control children. From the electrophysiological perspective, we recorded EEG under the Stop Signal Task modified with reward levels, which considers cognitive features of interest as insufficient motivational circuits recruitment. The methodology compares the supported diagnosis in two EEG channel setups (whole channel set and channels of interest in frontocentral area) and four frequency bands (Theta, Alpha, Beta rhythms, and a wideband). Results evidence an accuracy rate of 97.0% in the Beta band and in the channels where previous works found error-related negativity events. Such accuracy rate strongly supports the dual pathway hypothesis and motivational deficit concerning the pathophysiology of ADHD. It also demonstrates the utility of joining inhibitory and motivational paradigms with dynamic EEG analysis into a noninvasive and affordable diagnostic tool for ADHD patients.

Trajectories of reward availability moderate the impact of brief alcohol interventions on alcohol severity in heavy-drinking young adults.

Behavioral economic theory predicts that low access to environmental reward is a risk factor for alcohol use disorder (AUD). The Substance-Free Activity Session (SFAS) is a behavioral economic supplement to standard brief alcohol interventions that attempts to increase environmental reward and may therefore have beneficial effects, particularly for individuals with low levels of environmental reward. Participants were 393 college students who reported at least 2heavy-drinking episodes in the past month. Participants were randomly assigned to 1 of 3 conditions following a baseline assessment: a standard alcohol-focused brief motivational intervention plus relaxation training session (BMI+RT), BMI plus Substance-Free Activity Session (BMI+SFAS), or an assessment-only control condition (AO). In a secondary analysis of the data from this study, we used person-centered statistical techniques to describe trajectories of alcohol severity and environmental reward over a 16-month follow-up and examined whether environmental reward levels moderated the effectiveness of the interventions. Piecewise growth mixture modeling identified 2 trajectories of reward availability: low increasing (LR; n=120) and high stable (HR; n=273). Depressive symptoms, cannabis use, sensation seeking, and low life satisfaction were associated with a greater probability of classification in the LR trajectory. Alcohol severity was greater in the LR trajectory than the HR trajectory. For students in the LR trajectory, at 1, 6, and 12 months, BMI+SFAS led to greater increases in reward availability and reduced levels of alcohol severity compared with the BMI+RT and AO conditions and at 16months compared with AO. Young adults with low levels of environmental reward are at heightened risk for greater alcohol severity and may show greater benefit from brief alcohol interventions that focus on increasing substance-free reward than individuals who are not deficient in reward availability.

Service Learning Model Development in Medical Education

Many medical schools provide curricular or extra-curricular courses focused on service activities for social responsibility. Research on service learning varies from theory to teaching model, but research on service learning in medical education is difficult to find. Therefore, this study aims at developing a program that combines a medical educational curriculum and service activities. For the development of a service learning model in medical education, this study adopted Design Based Research method as a research method and developed a service learning model in medical education by analyzing problems in educational settings (2014-2017), reviewing literature, and going through a total of three formative cycles. As a result of applying the first Service Learning Model in Medical Education developed through literature analysis to the school field three cycles and revising it, we developed a final Service Learning Model in Medical Education with preparation, orientation, implementation, reflection, celebration, and evaluation s stages. The feelings of reward, interest, and satisfaction levels of the student’s analysis results showed continuously increased. In particular, the students showed higher levels of feelings of reward, interest and satisfaction in the final SL-ME model applied in 2017 than in the first SL-ME model applied in 2014. This study is significant in that it outlines the concepts, necessity, and instructional model of service learning necessary for the operation of service-related programs in medical education.

Investigating the Impact of Competition and Incentive Design on Performance of Crowdfunding Projects: A Case of Independent Movies

Recently, crowdfunding has become a popular e-commerce model based on web 2.0 platforms for fundraisers to collect funding from a large group of supporters using the Internet. However, many projects failed to reach their funding targets. Despite the growing interest of academic researchers and e-commerce professionals in identifying drivers of crowdfunding success, important factors like competition and incentive design have not received much attention in prior research. In this study we aim to fill this gap by investigating the impact of competition and incentive design on the performance of crowdfunding projects. Drawing upon literature of entrepreneurship, we develop a research model involving key factors such as competition intensity and the number of reward levels. Using real data of 209 independent movie projects of an online crowdfunding platform, we test the proposed hypotheses of the impact of competition and incentive design on crowdfunding success. Our results show that competition plays a significant role in crowdfunding performance. The higher competition pressure is, the lower performance of crowdfunding projects will be. We also find that factors such as the number of reward levels and the plan of attending movie festivals are essential to the success of crowdfunding projects, but the funding level of getting the top reward does not exert a significant impact. Our study contributes to the e-commerce literature by further exploring the mechanism of crowdfunding success with theoretical explanation and empirical evidence. Researchers and professionals can apply our theoretical findings regarding competition and incentive design in other e-commerce platforms. Furthermore, our results provide useful managerial insights and operational policies for project founders and managers of crowdfunding platforms.

Honey bees adjust colour preferences in response to concurrent social information from conspecifics and heterospecifics

Bees efficiently learn asocial and social cues to optimize foraging from fluctuating floral resources. However, it remains unclear how bees respond to divergent sources of social information, and whether such social cues might modify bees' natural preferences for nonsocial cues (e.g. flower colour), hence affecting foraging decisions. Here, we investigated honey bees', Apis mellifera , inspection and choices of unfamiliar flowers based on both natural colour preferences and simultaneous foraging information from conspecifics and heterospecifics. Individual honey bees' preferences for flowers were recorded when the reward levels of a learned flower type had declined and novel-coloured flowers were available where they would find either no social information or one conspecific and one heterospecific bumble bee, Bombus terrestris , each foraging from a different coloured flower (magenta or yellow). Honey bees showed a natural preference for magenta flowers. They modified their inspection of both types of flowers in response to conspecific and heterospecific social information. The presence of a conspecific demonstrator on the less-preferred yellow flower increased honey bees' inspection of yellow flowers and the likelihood of foraging on them, thus outweighing the original preference for magenta flowers. The presence of a heterospecific on a magenta flower increased honey bees' inspection of magenta flowers, but this effect was not observed when bumble bees fed on yellow flowers. Our results indicate that flower colour preferences of honey bees are rapidly adjusted in response to both conspecific and heterospecific presence, in different ways, with a preference for conspecific information possibly favouring the transmission of adaptive foraging information within species. • Honey bees' colour preferences are influenced by conspecifics and heterospecifics • Honey bees' colour preferences are overridden by conspecific social information. • Honey bees discriminate conspecific from bumble bees when making foraging decisions. • Conspecific social information is prioritized in a foraging context.

The influence of rewards on incidental memory: more does not mean better.

Studies have revealed that rewards promote long-term memory, even in an incidental way. However, most previous studies using the incidental paradigm have included two reward levels, and it is still not clear how the reward magnitude influences memory. Adopting the incidental paradigm and three reward levels, the current study revealed that the reward magnitude impacted 1-d delayed episodic memory in a nonlinear, inverted U-shaped pattern. An additional experiment showed that there was no reward effect in immediate episodic memory. Our results support the dopaminergic memory consolidation theory and further imply that the reward magnitude needs to be considered in the theory.

The experience matters: participation-related rewards increase the success chances of crowdfunding campaigns

ABSTRACT Crowdfunding recently emerged as an alternative funding channel for start-ups, creative artists and social endeavors. On specialized web platforms, project creators ask the crowd for support and provide in return a set of rewards, modulated according to the amount of support pledged. We analyze the role played by the type of reward in mobilizing pledgers; specifically, we look at self- and social-image enhancing rewards and to what extent they determine project success. Our data consist of the pledges to 346 projects hosted by Startnext, the biggest crowdfunding platform in Germany. We show that higher shares of reward levels that let pledgers participate in and experience the project are correlated with project success. Our paper contributes to the literature on the motivation driving pledgers in reward crowdfunding. A practical implication for the managing of a successful campaign is to employ the reward levels as a tool to involve the crowd in the project.

Interplay between midbrain and dorsal anterior cingulate regions arbitrates lingering reward effects on memory encoding

Rewarding events enhance memory encoding via dopaminergic influences on hippocampal plasticity. Phasic dopamine release depends on immediate reward magnitude, but presumably also on tonic dopamine levels, which may vary as a function of the average accumulation of reward over time. Using model-based fMRI in combination with a novel associative memory task, we show that immediate reward magnitude exerts a monotonically increasing influence on the nucleus accumbens, ventral tegmental area (VTA), and hippocampal activity during encoding, and enhances memory. By contrast, average reward levels modulate feedback-related responses in the VTA and hippocampus in a non-linear (inverted U-shape) fashion, with similar effects on memory performance. Additionally, the dorsal anterior cingulate cortex (dACC) monotonically tracks average reward levels, while VTA-dACC functional connectivity is non-linearly modulated (inverted U-shape) by average reward. We propose that the dACC computes the net behavioral impact of average reward and relays this information to memory circuitry via the VTA.

Tradeoffs in the evolution of plant farming by ants

Diverse forms of cultivation have evolved across the tree of life. Efficient farming requires that the farmer deciphers and actively promotes conditions that increase crop yield. For plant cultivation, this can include evaluating tradeoffs among light, nutrients, and protection against herbivores. It is not understood if, or how, nonhuman farmers evaluate local conditions to increase payoffs. Here, we address this question using an obligate farming mutualism between the ant Philidris nagasau and epiphytic plants in the genus Squamellaria that are cultivated for their nesting sites and floral rewards. We focused on the ants' active fertilization of their crops and their protection against herbivory. We found that ants benefited from cultivating plants in full sun, receiving 7.5-fold more floral food rewards compared to shade-cultivated plants. The higher reward levels correlated with higher levels of crop protection provided by the ants. However, while high-light planting yielded the greatest immediate food rewards, sun-grown crops contained less nitrogen compared to shade-grown crops. This was due to lower nitrogen input from ants feeding on floral rewards instead of insect protein gained from predation. Despite this tradeoff, farming ants optimize crop yield by selectively planting their crops in full sun. Ancestral state reconstructions across this ant-plant clade show that a full-sun farming strategy has existed for millions of years, suggesting that nonhuman farmers have evolved the means to evaluate and balance conflicting crop needs to their own benefit.

The role of reward and task demand in value-based strategic allocation of auditory comprehension effort

ObjectivesListeners who fail to optimize their allocation of effort during auditory comprehension tasks can experience from compromised performance, fatigue and stress, which might result in reduced engagement in social communication activities. Strategically allocating effort based on costs and perceived benefits are commonly observed in the research of effortful physical and visual behaviors. Whether people manage their effort in a similar manner in audition remains unclear. As the listening performance of people with normal hearing often serves as the goal of auditory rehabilitation for people with hearing loss, this study evaluated how strategy-induced effort allocation, challenged by reward and task demand, interactively impacted auditory comprehension in normal hearing adults. DesignA value-based strategic effort allocation paradigm was evaluated in 40 normal-hearing young adults. The paradigm included five levels of reward (motivation) and five levels of task demand (speech rate) that were independently manipulated. Effects of reward and task demand on performance accuracy and pupil dilation (a measure of auditory comprehension effort) were examined. ResultsThere was a significant interaction effect of reward and task demand on both pupil dilation and comprehension accuracy. At the response stage of speech comprehension processing, pupil dilation significantly decreased as the task demand increased at high reward levels. In contrast, pupil dilation did not vary significantly as a function of task demand at low reward levels. Reward significantly improved performance accuracy at fast and extremely fast rate conditions, but not at the slower rates. ConclusionsConsistent with previous studies on effort regulation, reward and task demand appear to be associated with auditory comprehension effort allocation in an interactive manner when strategic effort control was required to achieve a reward goal. The young normal-hearing listeners in this study prioritized their effort to relatively easy task items over difficult ones at high levels of reward, suggesting a cost-effective value-based strategic effort allocation. Reward significantly improved task performance in terms of accuracy at difficult listening conditions. These findings support the incorporation of affective factors (e.g., reward) and the utility of the value-based strategic effort allocation paradigm in the experimental setting to understand how clinically relevant factors (such as hearing loss and age) might change strategic auditory comprehension behavior.

Alterations in adolescent dopaminergic systems as a function of early mother-toddler attachment: A prospective longitudinal examination

Early experiences have the potential for outsized influence on neural development across a wide number of domains. In humans, many of the most important such experiences take place in the context of the mother-child attachment relationship. Work from animal models has highlighted neural changes in dopaminergic systems as a function of early care experiences, but translational research in humans has been limited. Our goal was to fill this gap by examining the longitudinal associations between early attachment experiences (assessed at 2.5 years) and neural responses to risk and rewards during adolescence (assessed at 13 years). Adolescence is a developmental period where sensitivity to rewards has important implications for behavior and long-term outcomes, providing an important window to study potential influences of early attachment experiences on reward processing. In order to address this question, 50 adolescents completed a risk and reward task during an fMRI scan, allowing us to assess differences in neural sensitivity to changes in risk level and reward amount as a function of early attachment experiences. Adolescents with insecure attachment histories showed blunted sensitivity to increasing risk levels in regions of the dorsal striatum, while also showing heightened sensitivity to increasing reward levels in the same region. These results highlight the importance of early attachment experiences for long-term neural development. Specifically, early exposure to more maladaptive relationships with caregivers may confer dual risks prospectively for adolescents, sensitizing them to rewarding outcomes while de-sensitizing them to potential risks associated with those behaviors, perhaps due to stress-related dopaminergic changes early in development.
