| Open AccessThe visual word form area (VWFA) is part of both language and attention circuitry
The visual word form area (VWFA) is a brain region associated with written language, but it has also been linked to visuospatial attention. Here, the authors reveal distinct structural and functional circuits linking VWFA with language and attention networks, and demonstrate that these circuits separately predict language and attention abilities.

| Open AccessIndividual face- and house-related eye movement patterns distinctively activate FFA and PPA
The fusiform face area and parahippocampal place area respond to face and scene stimuli respectively. Here, the authors show using fMRI that these brain areas are also preferentially activated by eye movements associated with looking at faces and scenes even when no images are shown.

| Open AccessHuman confidence judgments reflect reliability-based hierarchical integration of contextual information
Because our immediate observations are often ambiguous, we must use the context (prior beliefs) to guide inference, but the context may also be uncertain. Here, the authors show that humans can accurately estimate the reliability of the context and combine it with sensory uncertainty to form their decisions and estimate confidence.

Eye‐tracking is a valuable tool in cognitive science for measuring how attention is directed during visual scene exploration. Here, the authors introduce a new, touchscreen-based method that accomplishes the same goal via tracking finger movements.

| Open AccessInterference between overlapping memories is predicted by neural states during learning
Interference from overlapping memories can cause forgetting. Here, the authors show using fMRI decoding approaches that spontaneous reactivation of older memories during new encoding leads to integration, and less interference, between overlapping items.

| Open AccessGenetic evidence for assortative mating on alcohol consumption in the UK Biobank
From observational studies, alcohol consumption behaviours are known to be correlated in spouses. Here, Howe et al. use partners’ genotypic information in a Mendelian randomization framework and show that a SNP in the ADH1B gene associates with partner’s alcohol consumption, suggesting that alcohol consumption affects mate choice.

| Open AccessNeural representations of honesty predict future trust behavior
We tend to be more trusting of people who we know to be honest. Here, the authors show using fMRI that honesty-based trustworthiness is represented in the posterior cingulate cortex, dorsolateral prefrontal cortex and intraparietal sulcus, and predicts subsequent trust decisions.

| Open AccessClustering knowledge and dispersing abilities enhances collective problem solving in a network
Using agent-based models of a problem-solving task in a network, the authors show that clustering people of similar knowledge maintains solution diversity and increases long run system collective performance. Clustering those with similar abilities, however, lowers solution diversity and performance.

Auditory textures are sounds defined by a particular statistical distribution, e.g. as is produced by rain, or a swarm of insects. Here, the authors describe a striking perceptual illusion in which sound textures are heard to continue, even though they have in fact been replaced by white noise.

| Open AccessGoal congruency dominates reward value in accounting for behavioral and neural correlates of value-based decision-making
Decision-making research has confounded the reward value of options with their goal-congruency, as the task goal was always to pick the most rewarding option. Here, authors separately asked participants to select the least rewarding of a set of options, revealing a dominant role for goal congruency.

In order to perceive moving or changing objects, sensory information must be integrated over time. Here, using a visual sequential metacontrast paradigm, the authors show that integration occurs only when subsequent stimuli are presented within a discrete window of time after the initial stimulus.

| Open AccessIdeological differences in the expanse of the moral circle
How do liberals and conservatives differ in their expression of compassion and moral concern? The authors show that conservatives tend to express concern toward smaller, more well-defined, and less permeable social circles, while liberals express concern toward larger, less well-defined, and more permeable social circles.

Working memory involves a fronto-parietal brain network, but how the parts of this network are coordinated is unclear. Here, the authors show that fast brain activity at posterior sites is nested into prefrontal slow brain waves, with cognitive demand determining the slow wave phase involved.

| Open AccessDifferent brain networks mediate the effects of social and conditioned expectations on pain
Our experience of pain can be affected by our expectations about how much pain we will feel. Here, the authors show that both social information-driven expectations, and those based on personal experience, are both able to modulate pain, but by different neural pathways.

| Open AccessIntegration of cortical population signals for visual perception
Primary visual cortical neurons exhibit diverse responses to visual stimuli yet how these signals are integrated during visual perception is not well understood. Here, the authors show that optogenetic stimulation of neurons situated near the visually‐driven population leads to improved orientation detection in monkeys through changes in correlated variability.

The authors show that the dorsolateral prefrontal cortex (DLPFC) is involved in both on-task thought during increased environmental demands, and off-task thought during decreased demand–suggesting a role for the DLPFC in prioritising goals in a context-dependent manner.

| Open AccessExposure to violence affects the development of moral impressions and trust behavior in incarcerated males
In a sample of prisoners, the authors show how learning contributes to the link between exposure to violence (ETV) and maladaptive behavior. While ETV did not disrupt people's ability to learn others' propensity to harm, it did disrupt the development of subjective moral impressions and, subsequently, their ability to adjust levels of trust in others.
