Online behavioral data, such as digital traces from social media, have the potential to allow researchers an unprecedented new window into human behavior in ecologically valid everyday contexts. However, research using such data is often purely observational, which limits its usefulness for identifying causal relationships. Here we review recent innovations in experimental approaches to studying online

Do social networking sites (SNSs) influence well-being? According to the active-passive model of SNS use, the impact of SNSs on well-being depends on how they are used: Using SNSs actively to interact with other users positively affects well-being, whereas passive consumption of SNS content negatively affects well-being. However, emerging evidence suggests that the active-passive distinction is too

The Golden Rule of ethics in its negative form states that you should not do to others what you would not want others to do to you, and in its positive form states that you should do to others as you would want them to do to you. The Golden Rule is an ethical principle, but in virtual reality (VR), it can also be thought of as a paradigm for the promotion of prosocial behavior. This is because in VR

In this article, we argue that stigma may be an important, but heretofore underrecognized, source of heterogeneity in treatment effects of mental- and behavioral-health interventions. To support this hypothesis, we review recent evidence from randomized controlled trials and spatial meta-analyses suggesting that stigma may predict not only who responds more favorably to these health interventions (i

Skilled motor performance is essential in sports, the performing arts, various occupations, and many daily activities. Scientists and practitioners alike are therefore interested in understanding the conditions that influence the performance and learning of movement skills, and how they can be utilized to optimize training. In OPTIMAL theory, three motivational and attentional factors are key: enhanced

In many countries, individuals who have represented the majority group historically are decreasing in relative size and/or perceiving that they have diminished status and power compared with those self-identifying as immigrants or members of ethnic minority groups. These developments raise several salient and timely issues, including (a) how majority-group members’ cultural orientations change as a

The majority of research on infants’ and children’s understanding of emotional expressions has focused on their abilities to use emotional expressions to infer how other people feel. However, an emerging body of work suggests that emotional expressions support rich, powerful inferences not just about emotional states but also about other unobserved states, such as hidden events in the physical world

Sexual- and gender-minority individuals experience minority stress, which is hypothesized to underlie the mental-health disparities affecting these populations. Drawing on advances in the classification of mental disorders, we argue that transdiagnostic approaches hold great promise for understanding and reducing these disparities. In contrast to traditional diagnostic approaches, which have limited

Appreciating that varied stimuli belong to different categories requires that attention be differentially allocated to relevant and irrelevant features of those stimuli. Such selective attention ought to be definable and measurable in both humans and nonhuman animals. We first discuss the definition of attention and methods of assessing it in animals. We then introduce new experimental and computational

How do young children learn to organize the statistics of communicative input across milliseconds and months? Developmental science has made progress in elucidating how infants learn patterns in language and how infant-directed speech is engineered to ease short-timescale processing, but less is known about how children link perceptual experiences across multiple levels of processing within an interaction

Knowledge in memory is vast and not always relevant to the task at hand. Recent views suggest that the human cognitive system has evolved so that it includes goal-driven control mechanisms to regulate the level of activation of specific pieces of knowledge and make distracting or unwanted information in memory less accessible. This operation is primarily directed to facilitate the use of task-relevant

Narcissism is of great interest to behavioral scientists and the lay public. Research across the past 20 years has led to substantial progress in the conceptualization, measurement, and study of narcissism. This article reviews the current state of the field, identifying recent advances and outlining future directions. Advances include hierarchical conceptualizations of narcissism across one-factor

Across the millennia, human groups have evolved specific cultural and psychological adaptations to cope with collective threats, from terrorism to natural disasters to pathogens. In particular, research has identified cultural tightness, characterized by strict social norms and punishments, as one key adaptation that helps groups coordinate to survive collective threats. However, interferences with

This review summarizes results of field experiments examining individual behaviors across several market settings—from open-air markets to rideshare markets to tax-compliance markets—where people sort themselves into market roles wherein they make consequential decisions. Using three distinct examples from my own research on the endowment effect, left-digit bias, and omission bias, I showcase how field

Irritability is increasingly recognized as a significant clinical problem in youth. It is a criterion for multiple diagnoses and predicts the development of a wide range of disorders. Research on its etiology suggests that genetic and family environmental factors play a role, as do abnormalities in reward and cognitive-control neural circuitry. However, many of these effects are age dependent. Threat-responsive

The visual system evolved and develops to process the scenes, faces, and objects of the natural world, but people adapt this powerful system to process data within an artificial world of visualizations. To extract patterns in data from these artificial displays, viewers appear to use at least three perceptual tools, including a tool that extracts global statistics, one that extracts shapes within the

Traditionally, short-term memory (STM) has been assessed by asking participants to remember words, visual objects, or numbers for a short amount of time before their recall or recognition of those items is tested. However, this focus on memory for past sensory input might have obscured potential theoretical insights into the function of this cognitive faculty. Here, we suggest that STM may have an

Individual differences in attention abilities predict performance in a number of domains. We suggest that two aspects of attention are especially important for variation in attention abilities: intensity and consistency. We review evidence suggesting that individual differences in the amount of attention allocated to a task (intensity) and how consistently attention is allocated to a task (consistency)

Although empathy drives prosocial behaviors, it is not always a reliable source of information in moral decision making. In this essay, I integrate evolutionary theory, behavioral economics, psychology, and social neuroscience to demonstrate why and how empathy is unconsciously and rapidly modulated by various social signals and situational factors. This theoretical framework explains why decision

We describe an approach to anxiety, depressive, trauma-related, and other disorders, which we conceptualize as “emotional disorders” because of shared underlying dimensions uncovered by the study of traits or temperaments. We then explicate a functional model of emotional disorders based largely, but not exclusively, on the temperament of neuroticism and describe common factors that account for the

Perception, action, and intrinsic motivation play an essential role in early development, promoting the creation and refinement of new and more complex forms of behaviors as infants try a range of sensorimotor patterns in their environment. I use the example of infants’ reaching to illustrate how goal-directed action emerges from the intersection of seemingly distinct visual and proprioceptive-tactile-motor

Across species, caregivers exert a powerful influence on the neural and behavioral development of offspring. Increasingly, both animal and human research has highlighted specific patterns in caregivers’ behavior that may be especially important early in life, as well as neurobiological mechanisms linking early caregiving experiences with long-term affective behavior. Here we delineate evidence for

Achieving most goals demands cognitive control, yet people vary widely in their success at meeting these demands. Although motivation is known to be fundamental to determining success at achieving a goal, what determines motivation to perform a given task remains poorly understood. Here, we describe recent efforts toward addressing this question using the expected-value-of-control model, which simulates

Adolescence is a developmental period characterized by heightened attraction to rewards and risk-taking propensities. Dual-systems models portray the adolescent brain in terms of a maturational mismatch whereby brain systems involved in sensitivity to incentives become potentiated before impulse-control systems have matured. That perspective implies that relying on impulse inhibition to overcome temptation

Conflict resolution and intergroup reconciliation are difficult to achieve because of many social and psychological obstacles, such as people’s belief that members of a social group that is an adversary of their own group are mostly bad and essentially all the same. In this article, we introduce a novel intervention aimed at challenging these beliefs by exposing people to stories about individuals

A single treatment approach will never be sufficient to address the diversity of individuals with substance use disorders (SUDs). SUDs have historically defied definition through simple characterizations or models, and no single characterization has led to the development of broadly effective interventions. The range of dimensions of heterogeneity among individuals with SUDs, including severity of

Members of social categories defined by attributes such as sex, race, and age occupy certain types of social roles much more than members of other social categories do. The qualities that define these roles become associated with the category as a whole, thus forming a stereotype. In a vicious cycle, this stereotype then hinders category members’ movement into roles with different demands because their

Although research on the role of verbal working memory (WM) in language processing has focused on phonological maintenance, considerable evidence indicates that the maintenance of semantic information plays a more critical role. This article reviews studies of brain-damaged and healthy individuals demonstrating the contribution of semantic WM to language processing. On the sentence-comprehension side

The tremendous heterogeneity in functional and demographic characteristics of the over-65 age group presents challenges to effective marketing and public-health communications. Messages grounded on tacit assumptions that older people are frail, incompetent, and needy risk being overlooked by most of the older population; on the other hand, ignoring age-associated vulnerabilities is problematic. We

Mindfulness and motivation are both highly researched topics of great consequence for individual and social wellness. Using the lens of self-determination theory, we review evidence indicating that mindfulness is differentially related to different types of motivations, playing a facilitating role for highly autonomous forms of motivation, but not for externally controlled or introjected (self-controlling)

Loyalty has long been associated with being moral and upstanding, but recent research has begun documenting how loyalty can lead people to do unethical things. Here we offer an integrative perspective on loyalty and its outcomes. We suggest that a variety of bottom-up and top-down psychological processes lead individuals to be loyal to people and organizations they have obligations to, and that these

Sex and gender are key to people’s lives, and are the focus of scientific and popular interest and controversy. Sex-related psychological characteristics reflect more than socialization; they are influenced by sex hormones present during sensitive periods of development, particularly androgens that are present prenatally. Studies of females with congenital adrenal hyperplasia (CAH) show how prenatal

The influence of social relationships extends beyond emotional well-being to influence long-term physical-health outcomes, including mortality risk. Despite the varied measurement approaches used to examine social relationships within the health literature, the data can be synthesized using social connection as an organizing framework. This review discusses cumulative scientific evidence of links between

In engineering, form follows function. It is therefore difficult to understand an engineered object if one does not examine it in light of its function. Just as understanding the structure of a lock requires understanding the desire to secure valuables, understanding structures engineered by natural selection, including emotion systems, requires hypotheses about adaptive function. Social emotions reliably

Much of what people do is motivated by a concern with social evaluation. We argue that the process of figuring out what others value and making effective use of this information presents significant cognitive challenges. These challenges include reasoning about the relevance of different forms of information and making inferences about the mental lives of others. They also include modifying one’s behavior

Researchers often focus on age-related declines rather than the development associated with lifelong learning. Focusing on working-age people (those between the ages of 18 and 70), I describe age-related changes in abilities and motivation that affect lifelong learning and research showing that older learners can and do learn when content is aligned with their prior knowledge and interests. I further

Placebos are fake therapies that can induce real therapeutic effects, called placebo effects. It goes without saying that what matters for inducing a placebo effect is not so much the fake treatment itself, but rather the therapeutic ritual that is carried out, which is capable of triggering psychobiological mechanisms in the patient’s brain. Both laypersons and scientists often accept the phenomenon

Even before COVID-19, it was well known in psychological science that people’s well-being is strongly served by the quality of their close relationships. But is well-being also served by social contact with people who are known less well? In this article, we discuss three propositions that support the conclusion that the benefits of social contact also derive from interactions with acquaintances and

An article published in Current Directions a decade ago introduced the fundamental-motives framework and reviewed initial promising findings using this general approach. According to this framework, a recurring set of challenges and opportunities during human evolution gave rise to overarching motivational systems in the domains of self-protection, disease avoidance, social affiliation, status seeking

Not a week goes by without stories about scams appearing in popular media outlets. Given the ease with which scams can be circulated, they have become one of the most common crimes globally, inflicting high emotional, financial, and psychological tolls on millions of individuals. Despite their profound and pervasive impact, researchers know relatively little about why some individuals fall victim to

The first year of life is punctuated by explosions of growth in motor and language abilities. This is not a coincidence. The notion of developmental cascades provides a conceptual framework for considering ways in which advances in one component of a developing system can exert far-reaching and lasting change in other domains. In this article, I review evidence for the cascading effects of early motor

Market exchange and the ideologies that accompany it pervade human social interaction. How does this affect people’s beliefs about themselves, each other, and human nature? Here we describe market cognition as social inferences and behaviors that are intensified by market contexts. We focus on prosociality and two countervailing ways in which market cognition can affect it. On the one hand, marketplaces

Who is most likely to join and engage in extreme political action? Although traditional theories have focused on situational factors or group identity, an emerging science illustrates that tendencies for extreme political action may also be rooted in individuals’ idiosyncratic cognitive and affective dispositions. This article synthesizes cutting-edge evidence demonstrating that individuals’ cognitive

Research in psychology and related fields has documented a myriad of prediction biases, such as the underprediction of hedonic adaptation and the overprediction of other people’s concern for fairness. These prediction biases are ostensibly independent, each with its own cause. We argue, however, that many of these seemingly disparate biases are specific instances of a general bias—situation insensitivity:

Culture—the totality of traditions acquired in a community by social learning from other individuals—has increasingly been found to be pervasive not only in humans’ but in many other animals’ lives. Compared with learning on one’s own initiative, learning from others can be very much safer and more efficient, as the wisdom already accumulated by other individuals is assimilated. This article offers

Generations of psychologists have been taught that mental disorder can be carved into discrete categories, each qualitatively different from the others and from normality. This model is now outdated. A preponderance of evidence indicates that (a) individual differences in mental health (health vs. illness) are a matter of degree, not kind, and (b) broad mental-health conditions (e.g., internalizing)

Thinking of the world in mechanistic terms—how things work—is both cognitively natural and motivating for humans from the preschool years onward. Mechanisms have distinct structural properties that go far beyond mere causal facts. They typically contain layers of causal clusters and the systematic interactions between those clusters that give rise to the next level up. Following developments in the

Humans are fundamentally motivated to create a sense of shared reality—the perceived commonality of inner states (feeling, beliefs, and concerns about the world) with other people. This shared reality establishes a sense of both social connection and understanding the world. Research on shared reality has burgeoned in recent decades. We first review evidence for a basic building block of shared-reality

Although people report grave concern over their data privacy, they take little care to protect it. We suggest that this privacy paradox can be understood in part as the consequence of an evolutionary mismatch: Privacy intuitions evolved in an environment that was radically different from the one found online. This evolved privacy psychology leaves people disconnected from the consequence of online

Behavioral extremism (e.g., violent extremism, extreme humanism, or extreme athleticism) elicits fear, revulsion, pity, or admiration depending on the context. Its common image as exotic and esoteric makes extremism fascinating to audiences worldwide. The negative, antisocial and positive, prosocial cases of extremism are generally regarded as poles apart and as based on qualitatively different psychologies

Socioeconomic status (SES)—indexed via parent educational attainment, parent occupation, and family income—is a powerful predictor of children’s developmental outcomes. Variations in these resources predict large academic disparities among children from different socioeconomic backgrounds that persist over the years of schooling, perpetuating educational inequalities across generations. In this article

Models of episodic emotional memory typically concern why emotional events are more likely to be remembered than neutral events, focusing on interactions between the amygdala and other medial temporal lobe regions. But memories of emotional events can be distinguished by their affective tone and framing. We propose that the dorsomedial prefrontal cortex (dmPFC), a region that is increasingly recognized

The human fetus holds the key to unlocking the initial origins and predispositions of all aspects of human psychological development. Despite this, difficulties related to experimentally manipulating the behavior of the fetus to assess capacities have sidelined the fetus within the developmental sciences. Instead, the focus has been on the human infant. With new developments in the fields of obstetrics

One of the deepest insights in neuroscience is that sensory encoding should take advantage of statistical regularities. Humans’ visual experience contains many redundancies: Scenes mostly stay the same from moment to moment, and nearby image locations usually have similar colors. A visual system that knows which regularities shape natural images can exploit them to encode scenes compactly or guess

Is the pain of a loss greater in magnitude than the pleasure of a comparable gain? Studies that compare positive feelings about a gain with negative feelings about a comparable loss have found mixed answers to this question. The pain of a loss can be greater than, less than, or equal to the pleasure of a comparable gain. We offer a new approach to test hedonic loss aversion. This method uses emotional

The involvement of top-down processes in perception and cognition is widely acknowledged by now. In fields of research from predictions to inhibition, and from attentional guidance to affect, a great deal has already been charted. Integrating this newer understanding with accumulated findings from the past has made it clear that human experience is determined by a combination of both bottom-up and

The coronavirus disease 2019 (COVID-19) continues to claim lives worldwide. We propose that the science of habit formation offers strategies to increase adherence to COVID-19 prevention behaviors and has the potential to be lifesaving, particularly for high-risk groups. Eight elements of habit formation are highlighted here: addressing incorrect beliefs, setting goals, devising an action plan, establishing

Humans have a striking ability to coordinate their actions with each other to achieve joint goals. The tight interpersonal coordination that characterizes joint actions is achieved through processes that help with preparing for joint action as well as processes that are active while joint actions are being performed. To prepare for joint action, partners form representations of each other’s actions

The fields of psychology and neuroscience are in the midst of an explosion of research aimed at illuminating the human imagination—the ability to form thoughts and mental images that stretch beyond what is currently available to the senses. Imaginative thought is proving to be remarkably diverse, capturing the capacity to recall past experiences, consider what lies ahead, and understand other people’s

The tendency to view groups as constituting essentially different categories emerges early in development. To date, most attempts at understanding the origins of this tendency have focused on cognitive processes. Drawing from social-psychological and evolutionary theory, I propose that motivations—in particular, a need to belong—may be foundational for the development of social essentialism. I review
