Blair Saunders, Hause Lin, Marina Milyavskaya, Michael Inzlicht
The detection of conflict between incompatible impulses, thoughts, and actions is a ubiquitous source of motivation across theories of goal-directed action. In this overview, we explore the hypothesis that conflict is emotive, integrating perspectives from affective science and cognitive neuroscience. Initially, we review evidence suggesting that the mental and biological processes that monitor for information processing conflict-particularly those generated by the anterior midcingulate cortex-track the affective significance of conflict and use this signal to motivate increased control...

BACKGROUND: There is limited research to inform effective pedagogies for teaching global health to undergraduate medical students. Theoretically, using a combination of teaching pedagogies typically used in 'international classrooms' may prove to be an effective way of learning global health. This pilot study aimed to explore the experiences of medical students in Australia and Indonesia who participated in a reciprocal intercultural participatory peer e-learning activity (RIPPLE) in global health...

BACKGROUND: Rates of noncommunicable diseases (NCDs) such as type 2 diabetes are escalating in low and middle-income countries such as Brazil. Scalable primary care-based interventions are needed to improve self-management and clinical outcomes of adults with diabetes. This pilot study examines the feasibility, acceptability, and outcomes of training community health agents (CHAs) in Motivational Interviewing (MI)-based counseling for patients with poorly controlled diabetes in a primary care center in São Paulo, Brazil...

Hatred of terrorists is an obstacle to the implementation of effective counterterrorism policies-it invites indiscriminate retaliation, whereas many of the greatest successes in counterterrorism have come from understanding terrorists' personal and political motivations. Drawing from psychological research, traditional prejudice reduction strategies are generally not well suited to the task of reducing hatred of terrorists. Instead, in 2 studies, we explored education's potential ability to reduce extreme negative attitudes toward terrorists...

BACKGROUND: Short-term medical missions (STMMs) refer to the provision of direct pro bono medical services in lower and middle income countries for periods ranging from days to a few weeks by physicians from rich countries. Survey data have provided limited information on demographic and professional profiles of physicians as well as monetary and manpower inputs. Understanding why physicians participate, however, remains incomplete. The study's objective was to elicit physicians' motivations directly...

Recent work in the growing field of soft robotics has demonstrated a number of very promising technologies. However, to make a significant impact in real-world applications, these new technologies must first transition out of the laboratory through successful commercialization. Commercialization is perhaps the most critical future milestone facing the field of soft robotics today, and this process will reveal whether the apparent impact we now perceive has been appropriately estimated. Since 2012, Empire Robotics has been one of the first companies to attempt to reach this milestone through our efforts to commercialize jamming-based robotic gripper technology in a product called VERSABALL(®)...

Real-world speech learning often occurs in high pressure situations such as trying to communicate in a foreign country. However, the impact of pressure on speech learning success is largely unexplored. In this study, adult, native speakers of English learned non-native speech categories under pressure or no-pressure conditions. In the pressure conditions, participants were informed that they were paired with a (fictitious) partner, and that each had to independently exceed a performance criterion for both to receive a monetary bonus...

BACKGROUND: Seniors need sufficient balance and strength to manage in daily life, and sufficient physical activity is required to achieve and maintain these abilities. This can be a challenge, but fun and motivational exergames can be of help. However, most commercial games are not suited for this age group for several reasons. Many usability studies and user-centered design (UCD) protocols have been developed and applied, but to the best of our knowledge none of them are focusing on seniors' use of games for physical activity...

Thanks to the confluence of genomic technology and computational developments, the possibility of network inference methods that automatically learn large comprehensive models of cellular regulation is closer than ever. This perspective focuses on enumerating the elements of computational strategies that, when coupled to appropriate experimental designs, can lead to accurate large-scale models of chromatin state and transcriptional regulatory structure and dynamics. We highlight 4 research questions that require further investigation in order to make progress in network inference: (1) using overall constraints on network structure such as sparsity, (2) use of informative priors and data integration to constrain individual model parameters, (3) estimation of latent regulatory factor activity under varying cell conditions, and (4) new methods for learning and modeling regulatory factor interactions...

Germany saw an increase in numbers of refugees in 2015, with nearly a third being below the age of 18. Unaccompanied refugee minors (URMs) present an especially vulnerable group. In addition to pre-flight and flight stress, the acculturation process can work as potential stressor, and we wanted to explore attitudes towards URM. We conducted a study in a representative sample (n = 2524) of the German population (ages 14 years or older) between January and March 2016. Only 22.8% of participants thought that Germany could accompany more URM...

Despite their centrality to learning theories, strikingly little attention has been paid to the role of cognitions in efforts to understand associations between posttraumatic stress disorder (PTSD) and alcohol drinking. In the present study, we sought to examine information processing pathways for trauma and alcohol information, and the effects of posttraumatic stress and trauma cue exposure on these pathways. Participants were college students (N = 232; 49% female; Mage = 19.56,SD = 1.44) categorized into three diagnostic groups based on current PTSD status determined by structured clinical interview...

Purpose The purpose of the paper is to explore the notion of a diabetes language restricted code or "dialect" and its effect on people with diabetes. Language is a complex phenomenon comprising verbal and nonverbal components used to communicate in human interactions. Methods Information was collected from a literature review, during clinical consultations, and from an email survey. Results Language and the way clinicians use language affect motivation, behaviors, and outcomes of people with diabetes. Language is influenced by culture, experience, and familiarity with words and their use and is idiosyncratic...

The electroencephalography (EEG) data created in event-related potential (ERP) experiments have a complex high-dimensional structure. Each stimulus presentation, or trial, generates an ERP waveform which is an instance of functional data. The experiments are made up of sequences of multiple trials, resulting in longitudinal functional data and moreover, responses are recorded at multiple electrodes on the scalp, adding an electrode dimension. Traditional EEG analyses involve multiple simplifications of this structure to increase the signal-to-noise ratio, effectively collapsing the functional and longitudinal components by identifying key features of the ERPs and averaging them across trials...

The involvement of mitogen-activating extracellular kinase (MEK) in place conditioning may vary depending on the motivational sign (positive or negative) and nature (pharmacological or nociceptive) of the unconditioned stimulus (US) and on the phase (acquisition or expression) of the learning process. This study investigated the role of MEK on the acquisition and expression of ethanol-elicited (given 2 g/kg) backward (preference, CPP) and forward (aversion, CPA) place conditioning. The MEK inhibitor SL327 (50 mg/kg for CPP, and 50 and 100 mg/kg for CPA) was administered to CD-1 mice 60 minutes before an ethanol dose (acquisition) or 60 minutes before the post-conditioning tests (expression)...

BACKGROUND: Voltage-gated calcium channels (VGCCs) play a major role in brain functioning, including that of cognition-related structures such as cerebral cortex and hippocampus. Cellular mechanisms underlying learning and memory enhancing effect of the neuropeptide angiotensin IV (Ang IV) have been linked to VGCCs but only in respect of its long-term potentiation (LTP)-inducing effect. OBJECTIVE: To assess behaviorally effects of L- and T-type VGCCs blocking drugs in low, behaviorally inactive, doses on Ang IV facilitation of recall of aversively (foot-shock) and appetitively (curiosity for novelty) motivated behaviors...

Chronic mild or unpredictability stress produces a persistent depressive-like state. The main symptoms of depression include weight loss, despair, anhedonia, diminished motivation and mild cognition impairment, which could influence the ability of reward-related learning. In the present study, we aimed to evaluate the effects of chronic restraint stress on the performance of reward-related learning of rats. We used the exposure of repeated restraint stress (6h/day, for 28days) to induce depression-like behavior in rats...

Humans exhibit extensive large-scale cooperation, of a form unprecedented in the natural world. Here I suggest that this cooperation arises in our species alone because of our uniquely potent capacities for social learning, imitation and teaching, combined with the co-evolutionary feedbacks that these capabilities have generated on the human mind. Culture took human populations down evolutionary pathways not available to non-cultural species, either by creating conditions that promoted established cooperative mechanisms, such as indirect reciprocity and mutualism, or by generating novel cooperative mechanisms not seen in other taxa, such as cultural group selection...

REVIEW
Hans Alves, Alex Koch, Christian Unkelbach
Humans process positive information and negative information differently. These valence asymmetries in processing are often summarized under the observation that 'bad is stronger than good', meaning that negative information has stronger psychological impact (e.g., in feedback, learning, or social interactions). This stronger impact is usually attributed to people's affective or motivational reactions to evaluative information. We present an alternative interpretation of valence asymmetries based on the observation that positive information is more similar than negative information...

We present a novel and practical deep fully convolutional neural network architecture for semantic pixel-wise segmentation termed SegNet. This core trainable segmentation engine consists of an encoder network, a corresponding decoder network followed by a pixel-wise classification layer. The architecture of the encoder network is topologically identical to the 13 convolutional layers in the VGG16 network [1]. The role of the decoder network is to map the low resolution encoder feature maps to full input resolution feature maps for pixel-wise classification...

A range of evidence suggests that human reward functioning is partly driven by the endogenous circadian system, generating 24-hour rhythms in behavioural measures of reward activation. Reward functioning is multifaceted but literature to date is largely limited to measures of self-reported positive mood states. The aim of this study was to advance the field by testing for hypothesised diurnal variation in previously unexplored components of psychological reward: 'wanting', liking, and learning using subjective and behavioural measures...
