Social Learning of Placebo Effects in Pain: A Critical Review of the Literature and a Proposed Revised Model

Relatively recently, in 2009, experimental studies were undertaken to determine the role of social observational learning in forming hypoalgesic, analgesic and hyperalgesic responses to a placebo. The research findings obtained in studies published before 2018 were integrated and formed the basis of the theoretical model of social learning of placebo effects in pain proposed by Bajcar and Bąbel. This model considered the involvement of different types of modeling (ie, behavioral modeling, symbolic modeling, and verbal modeling) in shaping placebo hypoalgesia/analgesia and nocebo hyperalgesia. The model assumed that pain expectancies might be involved in observationally induced placebo effects in pain and that the effectiveness of observational learning in shaping placebo effects could be moderated by the observer's dispositions, especially empathy. Based on the latest research data, we propose a modified and significantly extended version of this model. The revised model includes the involvement of particular types of modeling in placebo effects and their role in shaping conscious pain-related expectancies. It explains the role of dispositional empathy in shaping observationally induced placebo effects. Notably, the extended version of the model considers the contribution of the characteristics of the observed person to the magnitude of placebo effects induced by social learning. PERSPECTIVE: The paper proposes a comprehensive theoretical approach to explaining the role of observational learning in shaping placebo effects in pain. The proposed model emphasizes the potential of this form of learning in shaping placebo responses and indicates factors that can modify the effectiveness of observational learning.

Cry for help as a root cause of poor symptom validity: A critical note

When patients fail symptom validity tests (SVTs) and/or performance validity tests (PVTs), their self-reported symptoms and test profiles are unreliable and cannot be taken for granted. There are many well-established causes of poor symptom validity and malingering is only of them. Some authors have proposed that a cry for help may underlie poor symptom validity. In this commentary, we argue that cry for help is a (1) metaphorical concept that is (2) difficult to operationalize and, at present, (3) impossible to falsify. We conclude that clinicians or forensic experts should not invoke cry for help as an explanation for poor symptom validity. To encourage conceptual clarity, we propose a tentative framework for explaining poor symptom validity.

Motivated Cognition in Cooperation

Successful cooperation is tightly linked to individuals' beliefs about their interaction partners, the decision setting, and existing norms, perceptions, and values. This article reviews and integrates findings from judgment and decision-making, social and cognitive psychology, political science, and economics, developing a systematic overview of the mechanisms underlying motivated cognition in cooperation. We elaborate on how theories and concepts related to motivated cognition developed in various disciplines define the concept and describe its functionality. We explain why beliefs play such an essential role in cooperation, how they can be distorted, and how this fosters or harms cooperation. We also highlight how individual differences and situational factors change the propensity to engage in motivated cognition. In the form of a construct map, we provide a visualization of the theoretical and empirical knowledge structure regarding the role of motivated cognition, including its many interdependencies, feedback loops, and moderating influences. We conclude with a brief suggestion for a future research agenda based on this compiled evidence.

Psychometric Properties and Factor Structure of the German Version of the Fear of COVID-19 Scale

Fear is a fundamental response in the face of a life-threatening pandemic, such as COVID-19. To assess COVID-19-related fear, the Fear of COVID-19 Scale (FCV-19S) has been recently developed and validated in many countries across the globe. The current study aimed to adapt the FCV-19S into German and to examine its psychometric properties. Participants (N = 866) were asked to complete the FCV-19S, report their perceived risk of contracting the virus, and their willingness to comply with mask wearing. Confirmatory Factor Analysis supported both a two-factor structure (emotional and somatic fear) and a more parsimonious one-factor model. Among demographic variables, only female gender was positively associated with the FCV-19S. Moreover, the measure was associated with increased risk perception and compliance with mask wearing. Results suggest that the FCV-19S has good psychometric properties in German and can be used in future work.

Integrating Social Cognition Into Domain-General Control: Interactive Activation and Competition for the Control of Action (ICON)

Social cognition differs from general cognition in its focus on understanding, perceiving, and interpreting social information. However, we argue that the significance of domain-general processes for controlling cognition has been historically undervalued in social cognition and social neuroscience research. We suggest much of social cognition can be characterized as specialized feature representations supported by domain-general cognitive control systems. To test this proposal, we develop a comprehensive working model, based on an interactive activation and competition architecture and applied to the control of action. As such, we label the model "ICON" (interactive activation and competition model for the control of action). We used the ICON model to simulate human performance across various laboratory tasks. Our simulations emphasize that many laboratory-based social tasks do not require socially specific control systems, such as those that are argued to rely on neural networks associated with theory-of-mind. Moreover, our model clarifies that perceived disruptions in social cognition, even in what appears to be disruption to the control of social cognition, can stem from deficits in social representation instead. We advocate for a "default stance" in social cognition, where control is usually general, but representation is specific. This study underscores the importance of integrating social cognition within the broader realm of domain-general control processing, offering a unified perspective on task processing.

How Do People Come to Judge What Is "Reasonable"? Effects of Legal and Sociological Systems on Human Psychology

How do people decide what is reasonable? People often have to make those judgments, judgments that can influence tremendously consequential decisions-such as whether to indict someone in a legal proceeding. In this article, we take a situated cognition lens to review and integrate findings from social psychology, judgment and decision-making, communication, law, and sociology to generate a new framework for conceptualizing judgments of reasonableness and their implications for how people make decisions, particularly in the context of the legal system. We theorize that differences in structural and social contexts create information asymmetries that shape people's priors about what is and is not reasonable and how they update their priors in the face of new information. We use the legal system as a context for exploring the implications of the framework for both individual and collective decision-making and for considering the practical implications of the framework for inequities in law and social policy.

Social semantics: the organization and grounding of abstract concepts

concepts, like justice and friendship, are central features of our daily lives. Traditionally, abstract concepts are distinguished from other concepts in that they cannot be directly experienced through the senses. As such, they pose a challenge for strongly embodied models of semantic representation that assume a central role for sensorimotor information. There is growing recognition, however, that it is possible for meaning to be 'grounded' via cognitive systems, including those involved in processing language and emotion. In this article, we focus on the specific proposal that social significance is a key feature in the representation of some concepts. We begin by reviewing recent evidence in favour of this proposal from the fields of psycholinguistics and neuroimaging. We then discuss the limited extent to which there is consensus about the definition of 'socialness' and propose essential next steps for research in this domain. Taking one such step, we describe preliminary data from an unprecedented large-scale rating study that can help determine how socialness is distinct from other facets of word meaning. We provide a backdrop of contemporary theories regarding semantic representation and social cognition and highlight important predictions for both brain and behaviour. This article is part of the theme issue 'Concepts in interaction: social engagement and inner experiences'.

Spelling out some unaddressed conceptual and methodological challenges in empirical lifespan research

The importance of taking a lifespan approach to describe and understand human development has long been acknowledged (e.g., Baltes, 1987). Nevertheless, theoretical or empirical research that actually encompasses the entire lifespan, that is, from early childhood to old age, is rare. This is not surprising given the challenges such an approach entails. Many of these challenges (e.g., establishing measurement invariance between age groups) have been addressed in the previous literature, but others have not yet been sufficiently considered. The main purpose of this article is to present several examples of such largely unaddressed conceptual and methodological challenges and reflect upon possible ways to address them. We discuss the usefulness of a lifespan approach and the generalization of the challenges to other research comparing different groups, such as gender, culture, or species.

What Can Educational Psychology Learn From, and Contribute to, Theory Development Scholarship?

One of the field of psychology’s stated goals is to produce scholarship with findings that benefit the world. Over the last 10 years, psychology scholarship and its presumed societal benefits have been called into question due to the field’s history of questionable research practices, racism, and epistemic oppression. Calls for methodological, ethical, and practical reforms are essential to building a psychological science that is just, effective, reliable, and beneficial. Recently, these calls have been complemented by a push to reform how theory is developed and used in psychology. There is great need for better understanding and implementation of theory development, both in the field of psychology broadly as well as in its subdisciplines, including educational psychology. At the same time, educational psychologists have much to contribute to the tripartite calls for methodological, ethical, and theory reforms. In this paper, I explore theory development in psychology by discussing the importance of developing both the descriptive and explanatory aspects of theory as well as the need to refine how theory is evaluated and integrated. Then, I review how innovations and practices in educational psychology can inform the broader theory reform movement in psychology writ large. Finally, I identify important future directions for further advancing theory reform in psychology, including addressing ableism in the field, increasing the field’s hospitability for theory revision, furthering theory development transparency, and more deeply integrating theory development into preparation programs.

The Cooperation Databank: Machine-Readable Science Accelerates Research Synthesis

Publishing studies using standardized, machine-readable formats will enable machines to perform meta-analyses on demand. To build a semantically enhanced technology that embodies these functions, we developed the Cooperation Databank (CoDa)—a databank that contains 2,636 studies on human cooperation (1958–2017) conducted in 78 societies involving 356,283 participants. Experts annotated these studies along 312 variables, including the quantitative results (13,959 effects). We designed an ontology that defines and relates concepts in cooperation research and that can represent the relationships between results of correlational and experimental studies. We have created a research platform that, given the data set, enables users to retrieve studies that test the relation of variables with cooperation, visualize these study results, and perform (a) meta-analyses, (b) metaregressions, (c) estimates of publication bias, and (d) statistical power analyses for future studies. We leveraged the data set with visualization tools that allow users to explore the ontology of concepts in cooperation research and to plot a citation network of the history of studies. CoDa offers a vision of how publishing studies in a machine-readable format can establish institutions and tools that improve scientific practices and knowledge.

Restoration of Attention by Rest in a Multitasking World: Theory, Methodology, and Empirical Evidence

In this work, we evaluate the status of both theory and empirical evidence in the field of experimental rest-break research based on a framework that combines mental-chronometry and psychometric-measurement theory. To this end, we (1) provide a taxonomy of rest breaks according to which empirical studies can be classified (e.g., by differentiating between long, short, and micro-rest breaks based on context and temporal properties). Then, we (2) evaluate the theorizing in both the basic and applied fields of research and explain how popular concepts (e.g., ego depletion model, opportunity cost theory, attention restoration theory, action readiness, etc.) relate to each other in contemporary theoretical debates. Here, we highlight differences between all these models in the light of two symbolic categories, termed the resource-based and satiation-based model, including aspects related to the dynamics and the control (strategic or non-strategic) mechanisms at work. Based on a critical assessment of existing methodological and theoretical approaches, we finally (3) provide a set of guidelines for both theory building and future empirical approaches to the experimental study of rest breaks. We conclude that a psychometrically advanced and theoretically focused research of rest and recovery has the potential to finally provide a sound scientific basis to eventually mitigate the adverse effects of ever increasing task demands on performance and well-being in a multitasking world at work and leisure.

The Six Components of Social Interactions: Actor, Partner, Relation, Activities, Context, and Evaluation

Social interactions are essential aspects of social relationships. Despite their centrality, there is a lack of a standardized approach to systematize social interactions. The present research developed (Study 1) and tested (Study 2) a taxonomy of social interactions. In Study 1 (5,676 descriptions of social interactions from N = 708 participants, age range 18–83 years), we combined a bottom-up approach based on the grounded theory with a top-down approach integrating existing empirical and theoretical literature to develop the taxonomy. The resulting taxonomy (APRACE) comprises the components Actor, Partner, Relation, Activities, Context, and Evaluation, each specified by features on three levels of abstraction. A social situation can be described by a combination of the components and their features on the respective abstraction level. Study 2 tested the APRACE using another dataset (N = 303, age range 18–88 years) with 1,899 descriptions of social interactions. The index scores of the six components, the frequencies of the features on the most abstract level, and their correlations were largely consistent across both studies, which supports the generalizability of the APRACE. The APRACE offers a generalizable tool for the comprehensive, parsimonious, and systematic description of social interactions and, thus, enables networked research on social interactions and application in a number of practical fields.

Empathy, an important but problematic concept

The concept of empathy as it is used in scholarly discourse has been challenged for over 50 years, yet the same ambiguities and controversies associated with the concept persist and, indeed, have accelerated with the accumulation of definitions, subconstructs that are included under the empathy umbrella, and measuring instruments. In this article we address the following interrelated problems: many definitions, authors not offering definitions, authors using instruments that do not match their definitions, authors not specifying definitions and measurements in cited studies, the jingle-jangle problem, and the persistent need for more construct validity research. In this Special Issue on empathy and its problems, authors bring new theoretical insights, creative research designs, and a critical focus on the empathy concept itself.

How Theoretical Models Can Inspire Advances in Research and Clinical Practice: The Example of Behavioral Addictions

Abstract. Aims: In this narrative position paper, we will summarize some examples of theoretical models of behavioral addictions. We will then make some suggestions for how theoretical models may inspire both research and clinical practice in the context of behavioral addictions. Results: Current theoretical models typically distinguish between general and specific risk factors. It is commonly argued that based on conditioning processes, affective responses to specific stimuli (cue-reactivity and craving) develop within the course of behavioral addictions. Diminished control over the behavior is reflected in reductions in inhibitory control and executive functioning. Cognitive distortions, attentional biases, and behavior-related expectancies are also considerable mechanisms. Theoretical models have been used to inspire advances not only in research but also in clinical practice. For example, theoretical models have inspired the development of standardized treatment protocols. Conclusions: If theoretical models contributed more consistently to scientific studies, a better understanding of the processes underlying specific mental disorders could be facilitated, which could then promote updates and modifications of the theoretical models and improvements in clinical practice. Close connections and stimulating discussions between theorists and therapists are very important and beneficial for advances over time.

When the Going Gets Tough, How Do We Perceive the Future?

People struggle to stay motivated to work toward difficult goals. Sometimes the feeling of difficulty signals that the goal is important and worth pursuing; other times, it signals that the goal is impossible and should be abandoned. In this article, we argue that how difficulty is experienced depends on how we perceive and experience the timing of difficult events. We synthesize research from across the social and behavioral sciences and propose a new, integrated model to explain how components of time perception interact with interpretations of experienced difficulty to influence motivation and goal-directed behavior. Although these constructs have been studied separately in previous research, we suggest that these factors are inseparable and that an integrated model will help us to better understand motivation and predict behavior. We conclude with new empirical questions to guide future research and by discussing the implications of this research for both theory and intervention practice.

Extracting Agency and Communion From the Big Five: A Four-Way Competition

Agency and communion are the two fundamental content dimensions in psychology. The two dimensions figure prominently in many psychological realms (personality, social, self, motivational, cross-cultural, etc.). In contemporary research, however, personality is most commonly measured within the Big Five framework. We developed novel agency and communion scales based on the items from the most popular nonpropriety measure of the Big Five-the Big Five Inventory. We compared four alternative scale-construction methods: expert rating, target scale, ant colony, and brute force. Across three samples (N_total = 942), all methods yielded reliable and valid agency and communion scales. Our research provides two main contributions. For psychometric theory, it extends knowledge on the four scale-construction methods and their relative convergence. For psychometric practice, it enables researchers to examine agency and communion hypotheses with extant Big Five Inventory data sets, including those collected in their own labs as well as openly accessible, large-scale data sets.

A decade of theory as reflected in Psychological Science (2009-2019)

The dominant belief is that science progresses by testing theories and moving towards theoretical consensus. While it’s implicitly assumed that psychology operates in this manner, critical discussions claim that the field suffers from a lack of cumulative theory. To examine this paradox, we analysed research published in Psychological Science from 2009–2019 (N = 2,225). We found mention of 359 theories in-text, most were referred to only once. Only 53.66% of all manuscripts included the word theory, and only 15.33% explicitly claimed to test predictions derived from theories. We interpret this to suggest that the majority of research published in this flagship journal is not driven by theory, nor can it be contributing to cumulative theory building. These data provide insight into the kinds of research psychologists are conducting and raises questions about the role of theory in the psychological sciences.

Mind Meets Machine: Towards a Cognitive Science of Human-Machine Interactions

As robots advance from the pages and screens of science fiction into our homes, hospitals, and schools, they are poised to take on increasingly social roles. Consequently, the need to understand the mechanisms supporting human-machine interactions is becoming increasingly pressing. We introduce a framework for studying the cognitive and brain mechanisms that support human-machine interactions, leveraging advances made in cognitive neuroscience to link different levels of description with relevant theory and methods. We highlight unique features that make this endeavour particularly challenging (and rewarding) for brain and behavioural scientists. Overall, the framework offers a way to study the cognitive science of human-machine interactions that respects the diversity of social machines, individuals' expectations and experiences, and the structure and function of multiple cognitive and brain systems.

Statements About the Pervasiveness of Behavior Require Data About the Pervasiveness of Behavior

Despite recent close attention to issues related to the reliability of psychological research (e.g., the replication crisis), issues of the validity of this research have not been considered to the same extent. This paper highlights an issue that calls into question the validity of the common research practice of studying samples of individuals, and using sample-based statistics to infer generalizations that are applied not only to the parent population, but to individuals. The lack of ergodicity in human data means that such generalizations are not justified. This problem is illustrated with respect to two common scenarios in psychological research that raise questions for the sorts of theories that are typically proposed to explain human behavior and cognition. The paper presents a method of data analysis that requires closer attention to the range of behaviors exhibited by individuals in our research to determine the pervasiveness of effects observed in sample data. Such an approach to data analysis will produce results that are more in tune with the types of generalizations typical in reports of psychological research than mainstream analysis methods.

Construct Validation of Experimental Manipulations in Social Psychology: Current Practices and Recommendations for the Future

Experimental manipulations in social psychology must exhibit construct validity by influencing their intended psychological constructs. Yet how do experimenters in social psychology attempt to establish the construct validity of their manipulations? Following a preregistered plan, we coded 348 experimental manipulations from the 2017 issues of the Journal of Personality and Social Psychology. Representing a reliance on "on-the-fly" experimentation, the vast majority of these manipulations were created ad hoc for a given study and were not previously validated before implementation. A minority of manipulations had their construct validity evaluated by pilot testing before implementation or via a manipulation check. Of the manipulation checks administered, most were face valid, single-item self-reports, and only a few met criteria for "true" validation. In aggregate, roughly two fifths of manipulations relied solely on face validity. To the extent that they are representative of the field, these results suggest that best practices for validating manipulations are not commonplace-a potential contributor to replicability issues. These issues can be remedied by validating manipulations before implementation using validated manipulation checks, standardizing manipulation protocols, estimating the size and duration of manipulations' effects, and estimating each manipulation's effects on multiple constructs within the target nomological network.

Challenges and opportunities for top-down modulation research in cognitive psychology

Studying social modulation of cognitive processes holds much promise for illuminating how, where, when and why social factors influence how we perceive and act in the world, as well as providing insight into the underlying cognitive mechanisms. This is no small objective; it reflects an ambitious programme of research. At present, based on the modal theoretical and methodological approach, we suggest that several challenges exist to achieving such lofty aims. These challenges span an overreliance on a simplistic dichotomy between "top-down" and "bottom-up" modulation, a lack of specificity about mechanisms that renders clear interpretations difficult, and theories that largely test against null hypotheses. We suggest that these challenges present several opportunities for new research and we encourage the field to abandon simplistic dichotomies and connect much more with existing research programmes such as semantics, memory and attention, which have all built diverse research platforms over many decades and that can help shape how social modulation is conceptualised and studied from a cognitive and brain perspective. We also outline ways that stronger theoretical positions can be taken, which avoid comparing to null hypotheses, and endorse methodological reform through fully embracing proposals from the open science movement and "credibility revolution". We feel that by taking these opportunities, the field will have a better chance of reaching its potential to build a cumulative science of social modulation that can inform understanding of basic cognitive and brain systems, as well as real-life social interactions and the varied abilities observed across the Autism Spectrum.

Two kinds of theory: What psychology can learn from Einstein

A century ago, Einstein distinguished between two kinds of theory—theories of principle and constructive theories. These have separate but complementary roles to play in the advancement of knowledge, in the manner in which they relate to data and in how they are developed. The different kinds of theory carry implications for what kinds of data we produce and for how they are put to use. We outline Einstein’s distinction and the model of theory formation that it involves. We then use the distinction to look at some of the discussion of scientific practice in psychology, particularly recent work on the need for more theoretical, rather than purely methodological, sophistication. We argue in agreement with Einstein that the distinction is a useful one and that adopting it as a tenet of theoretical development requires a renewed commitment to a natural history of psychology.

Putting the Nonsocial Into Social Neuroscience: A Role for Domain-General Priority Maps During Social Interactions

Whether on a first date or during a team briefing at work, people’s daily lives are inundated with social information, and in recent years, researchers have begun studying the neural mechanisms that support social-information processing. We argue that the focus of social neuroscience research to date has been skewed toward specialized processes at the expense of general processing mechanisms with a consequence that unrealistic expectations have been set for what specialized processes alone can achieve. We propose that for social neuroscience to develop into a more mature research program, it needs to embrace hybrid models that integrate specialized person representations with domain-general solutions, such as prioritization and selection, which operate across all classes of information (both social and nonsocial). To illustrate our central arguments, we first describe and then evaluate a hybrid model of information processing during social interactions that (a) generates novel and falsifiable predictions compared with existing models; (b) is predicated on a wealth of neurobiological evidence spanning many decades, methods, and species; (c) requires a superior standard of evidence to substantiate domain-specific mechanisms of social behavior; and (d) transforms expectations of what types of neural mechanisms may contribute to social-information processing in both typical and atypical populations.

The Moral Psychology of Raceless, Genderless Strangers

Moral psychology uses tightly controlled scenarios in which the identities of the characters are either unspecified or vague. Studies with raceless, genderless strangers help to highlight the important structural elements of moral acts (e.g., intention, causation, harm) but may not generalize to real-world judgments. As researchers have long shown, social judgments hinge on the identities (e.g., race, gender, age, religion, group affiliation) of both target and perceiver. Asking whether people generally condemn “shooting someone” is very different from asking whether liberals as opposed to conservatives condemn “a White police officer shooting a Black suspect.” We argue for the importance of incorporating identity into moral psychology. We briefly outline the central role of identity in social judgments before reviewing current theories in moral psychology. We then advocate an expanded person-centered morality—synthesizing moral psychology with social cognition—to better capture everyday moral judgments.

Social Psychological Theory as History: Outlining the Critical-Historical Approach to Theory

The mainstream epistemology of social psychology is markedly ahistorical, prioritizing the quantification of processes assumed to be lawful and generalizable. Social psychologists often consider theory to be either a practical tool for summarizing what is known about a problem area and making predictions or a torch that illuminates the counterintuitive causal force underlying a variety of disparate phenomena. I propose a third vision of critical-historical theory. From this perspective, theories should be committed to deep interdisciplinarity and historical validity claims-understanding individual and group experiences as part of historically contingent forces. Theories also should be critical, containing an awareness of the researcher as implicated in the social process and committed to actively improving society. To demonstrate its viability, I review classic works from the history of the discipline that exemplify critical-historical theory and offer concrete implications for theorists interested in employing this approach in their own work.

Fluid intelligence and working memory support dissociable aspects of learning by physical but not observational practice

Humans have a remarkable ability to learn by watching others, whether learning to tie an elaborate knot or play the piano. However, the mechanisms that translate visual input into motor skill execution remain unclear. It has been proposed that common cognitive and neural mechanisms underpin learning motor skills by physical and observational practice. Here we provide a novel test of the common mechanism hypothesis by testing the extent to which certain individual differences predict observational as well as physical learning. Participants (N = 92 per group) either physically practiced a five-element key-press sequence or watched videos of similar sequences before physically performing trained and untrained sequences in a test phase. We also measured cognitive abilities across participants that have previously been associated with rates of learning, including working memory and fluid intelligence. Our findings show that individual differences in working memory and fluid intelligence predict improvements in dissociable aspects of motor learning following physical practice, but not observational practice. Working memory predicts general learning gains from pre- to post-test that generalise to untrained sequences, whereas fluid intelligence predicts sequence-specific gains that are tied to trained sequences. However, neither working memory nor fluid intelligence predict training gains following observational learning. Therefore, these results suggest limits to the shared mechanism hypothesis of physical and observational learning. Indeed, models of observational learning need updating to reflect the extent to which such learning is based on shared as well as distinct processes compared to physical learning. We suggest that such differences could reflect the more intentional nature of learning during physical compared to observational practice, which relies to a greater extent on higher-order cognitive resources such as working memory and fluid intelligence.

The Flatland Fallacy: Moving Beyond Low-Dimensional Thinking

Psychology is a complicated science. It has no general axioms or mathematical proofs, is rarely directly observable, and is the only discipline in which the subject matter (i.e., human psychological phenomena) is also the tool of investigation. Like the Flatlanders in Edwin Abbot's famous short story (), we may be led to believe that the parsimony offered by our low-dimensional theories reflects the reality of a much higher-dimensional problem. Here we contend that this "Flatland fallacy" leads us to seek out simplified explanations of complex phenomena, limiting our capacity as scientists to build and communicate useful models of human psychology. We suggest that this fallacy can be overcome through (a) the use of quantitative models, which force researchers to formalize their theories to overcome this fallacy, and (b) improved quantitative training, which can build new norms for conducting psychological research.

Outsiders’ Thoughts on Generating Self-Regulatory-Depletion (Fatigue) Effects in Limited-Resource Experiments

We offer thoughts pertaining to purported conceptual and replication crises that have been discussed in relation to the limited-resource model (LRM) of self-control, functioning as crisis outsiders who have been conducting related research concerned with determinants and cardiovascular correlates of effort. Guiding analyses in our laboratory convey important lessons about experimental generation of the now-classic LRM self-regulatory-fatigue effect on control. They do so by drawing attention to conditions that must be met in fatigue-induction and fatigue-influence phases of relevant experiments. One fundamental lesson is that even highly standardized fatigue-induction protocols cannot be expected to consistently allow definitive tests of this effect. Another is that the effect might emerge consistently only in a behavioral-restraint “sweet spot” of sorts—a multidimensional motivational space wherein rested study participants view restraint as possible and worthwhile and fatigued participants do not. Implications are identified and discussed.

Revenge: A Multilevel Review and Synthesis

Why do people take revenge? This question can be difficult to answer. Vengeance seems interpersonally destructive and antithetical to many of the most basic human instincts. However, an emerging body of social scientific research has begun to illustrate a logic to revenge, demonstrating why revenge evolved in humans and when and how people take revenge. We review this evidence and suggest that future studies on revenge would benefit from a multilevel perspective in which individual acts of revenge exist within higher-level cultural systems, with the potential to instigate change in these systems over time. With this framework, we can better understand the interplay between revenge's psychological properties and its role in cultural evolution.

Neural Integration in Body Perception

The perception of other people is instrumental in guiding social interactions. For example, the appearance of the human body cues a wide range of inferences regarding sex, age, health, and personality, as well as emotional state and intentions, which influence social behavior. To date, most neuroscience research on body perception has aimed to characterize the functional contribution of segregated patches of cortex in the ventral visual stream. In light of the growing prominence of network architectures in neuroscience, the current article reviews neuroimaging studies that measure functional integration between different brain regions during body perception. The review demonstrates that body perception is not restricted to processing in the ventral visual stream but instead reflects a functional alliance between the ventral visual stream and extended neural systems associated with action perception, executive functions, and theory of mind. Overall, these findings demonstrate how body percepts are constructed through interactions in distributed brain networks and underscore that functional segregation and integration should be considered together when formulating neurocognitive theories of body perception. Insight from such an updated model of body perception generalizes to inform the organizational structure of social perception and cognition more generally and also informs disorders of body image, such as anorexia nervosa, which may rely on atypical integration of body-related information.

Is Ego Depletion Real? An Analysis of Arguments

An influential line of research suggests that initial bouts of self-control increase the susceptibility to self-control failure (ego depletion effect). Despite seemingly abundant evidence, some researchers have suggested that evidence for ego depletion was the sole result of publication bias and p-hacking, with the true effect being indistinguishable from zero. Here, we examine (a) whether the evidence brought forward against ego depletion will convince a proponent that ego depletion does not exist and (b) whether arguments that could be brought forward in defense of ego depletion will convince a skeptic that ego depletion does exist. We conclude that despite several hundred published studies, the available evidence is inconclusive. Both additional empirical and theoretical works are needed to make a compelling case for either side of the debate. We discuss necessary steps for future work toward this aim.

Strong scientific theorizing is needed to improve replicability in psychological science

The target article makes the important case for making replicability mainstream. Yet, their proposal targets a symptom, rather than the underlying cause of low replication rates. We argue that psychological scientists need to devise stronger theories that are more clearly falsifiable. Without strong, falsifiable theories in the original research, attempts to replicate the original research are nigh uninterpretable.

How to think about emotion and morality: circles, not arrows

Emotion and morality are powerful conscious experiences. There are two ways to think about their psychological basis: arrows and circles. Arrows ground each experience in its own specialized mechanism (mechanism x causes phenomenon x; mechanism y causes phenomenon y). Examples of arrows include when feelings of disgust are attributed to a specialized 'disgust circuit' and when judgments of impurity are attributed to a specialized 'purity foundation.' In contrast, circles - Venn diagrams - describe experiences as emerging from the overlap of more fundamental domain-general processes (different combinations of processes a, b, c cause both phenomena x and y). Circles are used by constructionist theories of emotion and morality, including the Theory of Dyadic Morality, which grounds moral judgment in the combination of norm violations, negative affect, and perceived harm. Despite the intuitive popularity of arrows, we show that scientific evidence is more consistent with circles.
