Mindfulness interventions have been shown to improve several subcomponents of attention; however, the psychological mechanisms driving these improvements are unknown. Mindfulness interventions train individuals to monitor present moment experiences while adopting an attitude of acceptance toward these experiences. We conducted a theoretically driven randomized controlled trial to test the putative

The foundational tenet of brain training is that general cognitive functioning can be enhanced by completing computerized games, a notion that is both intuitive and appealing. Moreover, there is strong incentive to improve our cognitive abilities, so much so that it has driven a billion-dollar industry. However, whether brain training can really produce these desired outcomes continues to be debated

When the outcome is binary, psychologists often use nonlinear modeling strategies such as logit or probit. These strategies are often neither optimal nor justified when the objective is to estimate causal effects of experimental treatments. Researchers need to take extra steps to convert logit and probit coefficients into interpretable quantities, and when they do, these quantities often remain difficult

We examine which social comparisons most affect happiness with pay that is unequally distributed (e.g., salaries and bonuses). We find that ensemble representation-attention to statistical properties of distributions such as their range and mean-makes the proximal extreme (i.e., the maximum or minimum) and distribution mean salient social comparison standards. Happiness with a salary or bonus is more

Pragmatic theories and computational models of reference must account for people's frequent use of redundant color adjectives (e.g., referring to a single triangle as "the blue triangle"). The standard pragmatic view holds that the informativity of a referential expression depends on pragmatic contrast: Color adjectives should be used to contrast competitors of the same kind to preempt an ambiguity

A substantial amount of research has been conducted to uncover factors underlying the pronounced individual differences in spatial navigation. Spatial working memory capacity (SWM) is shown to be one important factor. In other domains such as reading comprehension, the role of working memory capacity in task performance differences depends on the difficulty of other task demands. In the current study

The social environment provides a sampling space for making informed inferences about features of the world at large, such as the distribution of preferences, risks, behaviors, or other events. How do people search this sampling space and make inferences based on the instances sampled? Inspired by existing models of bounded rationality and in accord with research on the structure of social memory,

Positive social connections improve wellbeing. Technology increasingly affords a wide variety of media that people can use to connect with others, but not all media strengthen social connection equally. Optimizing wellbeing, therefore, requires choosing how to connect with others wisely. We predicted that people's preferences for communication media would be at least partly guided by the expected costs

Questions of how we know our own and other minds, and whether metacognition and mindreading rely on the same processes, are longstanding in psychology and philosophy. In Experiment 1, children/adolescents with autism (who tend to show attenuated mindreading) showed significantly lower accuracy on an explicit metacognition task than neurotypical children/adolescents, but not on an allegedly metacognitive

The dual-strategy model of reasoning suggests that when people reason they can either use (a) a statistical strategy which generates an estimation of conclusion likelihood using a rapid form of associative processing or (b) a counterexample strategy which identifies potential counterexamples to a conclusion using a more conscious working memory intensive process. Previous results suggest that strategy

Poor people are punished more frequently and more severely than are wealthy people for their transgressions, suggesting that an agent's wealth affects how they are morally evaluated. To our knowledge, this has not been tested empirically. An initial study found that people expect the poor to be judged more harshly than the wealthy. Several other experiments consistently found that the reverse was true:

Number processing and visual hierarchical processing (global-local processing) have much in common. However, the shared aspects of number processing and global-local processing have not been investigated so far. Most visual stimuli are hierarchical with global structures made up of local parts. Processing of global and local aspects occurs in parallel and the global advantage effect indicates faster

Psychologists are beginning to uncover the rational basis for many of the biases revealed over the last 50 years in deductive and causal reasoning, judgment, and decision making. In this article, it is argued that a manipulation, experiential learning, shown to be effective in judgment and decision making, may elucidate the rational underpinning of the implicit negation effect in conditional inference

Human behavior can be classified into 2 basic categories: execution of responses and withholding responses. This classification is used in go/no-go training, where people respond to some objects and withhold their responses to other objects. Despite its simplicity, there is now substantial evidence that such training is powerful in changing human behavior toward such objects. However, it is poorly

The purpose of this article is to examine the statistical characteristics of binary sequences with the aim of uncovering the implicit cues that people use when making forecasts of what comes next. Information theory was used to quantify these statistical characteristics. In 2 experiments people were presented with 100 intact sequences of 20 Xs and Os and simply asked to forecast whether the 21st event

Most music is temporally organized within a metrical hierarchy, having nested periodic patterns that give rise to the experience of stronger (downbeat) and weaker (upbeat) events. Musical meter presumably makes it possible to dance, sing, and play instruments in synchrony with others. It is nevertheless unclear whether or not listeners perceive multiple levels of periodicity simultaneously, and if

Although people seek to avoid expenditure of cognitive effort, reward incentives can increase investment of processing resources in challenging situations that require cognitive control, resulting in improved performance. At the same time, subjective value is relative, rather than absolute: The value of a reward is increased if the local context is reward-poor versus reward-rich. Although this notion

Because work songs are ubiquitous around the world, singing while working and performing a task with a coactor is presumably beneficial for both joint action and individual task performance. The present study investigated the impact of interpersonal rhythmic vocal interaction on interpersonal phase relations and on individual motor timing performance, which was evaluated by a synchronization-continuation

Investigates the hypothesis that spatial processes are involved in judgments on membership in a category. It is argued that membership versus nonmembership of an object or a concept, in a category, is spatially simulated in mental space by a minimal continuum with 2 levels, left for membership and right for nonmembership. In analogy to other embodied dimensions (e.g., time line or number line), the

In this research, we document the existence of broad ideological differences in judgment and decision-making confidence and examine their source. Across a series of 14 studies (total N = 4,575), we find that political conservatives exhibit greater judgment and decision-making confidence than do political liberals. These differences manifest across a wide range of judgment tasks, including both memory

Cognitively suppressing the retrieval of an unwanted memory causes its forgetting and, in the meantime, disrupts hippocampal functions. The present study investigated whether retrieval suppression induces virtual amnesia, which disturbs any existing memories that are reactivated in the temporal vicinity but are otherwise unrelated to the targets of suppression. Participants performed retrieval suppression

The matching law describes the allocation of behavior over a wide range of settings, including laboratory experimental chambers, forest foraging patches, sports arenas, and board games. Interestingly, matching persists in settings in which economic analyses predict quite different distributions of behavior, and it also differs systematically from probability matching. We tested whether the matching

To help children navigate their social environments, adults must understand what children know about race, and when they acquire this knowledge. Across three preregistered studies, we tested United States adults' knowledge of when children first use race to categorize and ascribe traits to others. Participants wildly-and uniquely-misjudged children's abilities to process race. This inaccuracy was consequential:

Reports an error in "Opposing contributions of psychologically distinct components of empathy to empathic accuracy" by Ananya Mayukha, Isabel Andrade and Jeremy Cone (Journal of Experimental Psychology: General, Advanced Online Publication, May 14, 2020, np). In the original article, significance levels indicated by the asterisks in Table 2 are incorrect. The corrected Table 2 is given in erratum.

Cognitive tasks that produce reliable and robust effects at the group level often fail to yield reliable and valid individual differences. An ongoing debate among attention researchers is whether conflict resolution mechanisms are task-specific or domain-general, and the lack of correlation between most attention measures seems to favor the view that attention control is not a unitary concept. We have

The authors suggest that mere attention increases the perceived severity of environmental risks because attention increases the fear and distinctiveness of attended risks. In Experiments 1 and 2, participants were exposed to images of multiple environmental risks, with attention repeatedly oriented to a subset of these risks. Participants subsequently perceived attended risks to be more severe, more

When observers must identify targets among distractors in a rapid serial visual presentation (RSVP) stream, distractor intrusion errors are frequent, demonstrating the difficulty of allocating attention to the right object at the right moment in time. However, the mechanisms responsible for such intrusion errors remain disputed. We propose a new attentional engagement account of selective visual processing

From an early age, humans intuitively expect physical objects to obey core principles, including continuity (objects follow spatiotemporally continuous paths) and solidity (two solid objects cannot occupy the same space at the same time). These 2 principles are sometimes viewed as deriving from a single overarching "persistence" principle. Indeed, violations of solidity where one solid object seemingly

Prolonged deprivation of personal control induces cognitive, motivational, and affective impairments that can lead to learned helplessness syndrome. Research on cognitive mechanisms involved in responding to uncontrollable events reveals a critical role of lack of contingency between one's action and outcomes. However, the impact of experienced uncontrollability on individuals' sense of self-agency

Affective forecasting (AF), the ability to predict one's future feelings, is important for decision making. We posit that AF entails the ability to maintain and evaluate an emotional feeling state, and thus requires affective working memory (AWM; Mikels & Reuter-Lorenz, 2019). To test this hypothesis, a series of studies investigated whether individual differences in AWM are related to AF ability.

This article investigated how network growth algorithms-preferential attachment, preferential acquisition, and lure of the associates-relate to the acquisition of words in the phonological language network, where edges are placed between words that are phonologically similar to each other. Through an archival analysis of age-of-acquisition norms from English and Dutch and word learning experiments

A classic phenomenon known as prototype preference effect (PPE) or beauty-in-averageness effect is that prototypical exemplars of a neutral category are preferred over atypical exemplars. This PPE has been explained in terms of deviance avoidance, hedonic fluency, or preference for certainty and familiarity. However, typicality also facilitates greater activation of category-related information. Thus

Individual differences in cognitive control have been suggested to act as a domain-general bottleneck constraining performance in a variety of cognitive ability measures, including but not limited to fluid intelligence, working memory capacity, and processing speed. However, owing to psychometric problems associated with the measurement of individual differences in cognitive control, it has been challenging

We propose and test the overconfidence transmission hypothesis, which predicts that individuals calibrate their self-assessments in response to the confidence others display in their social group. Six studies that deploy a mix of correlational and experimental methods support this hypothesis. Evidence indicates that individuals randomly assigned to collaborate in laboratory dyads converged on levels

Human and nonhuman animals have a remarkable capacity to rapidly estimate the quantity of objects in the environment. The dominant view of this ability posits an abstract numerosity code, uncontaminated by nonnumerical visual information. The present study provides novel evidence in contradiction to this view by demonstrating that number and cumulative surface area are perceived holistically, classically

In this article we introduce the shared features principle, which refers to the idea that when 2 stimuli share 1 feature, people often assume that they share other features as well. This principle can be recognized in several known psychological phenomena, most of which were until now never considered to be related in this way. To illustrate the generative power of the principle, we report 8 preregistered

What is happiness? Is happiness about feeling good or about being good? Across 5 studies, we explored the nature and origins of our happiness concept developmentally and cross-linguistically. We found that surprisingly, children as young as age 4 viewed morally bad people as less happy than morally good people, even if the characters all have positive subjective states (Study 1). Moral character did

We propose a dynamic theory of decisions not to choose which of 2 options is correct. Such "do not-know" judgments are of theoretical and practical importance in domains ranging from comparative psychology, psychophysics, episodic memory, and metacognition to applied areas including educational testing and eyewitness testimony. However, no previous theory has provided a detailed quantitative account

People are normally restricted from accessing property without permission from the owner. The principle that nonowners are excluded from property is central to theories of ownership, and previous findings suggest it could be a core feature of the psychology of ownership. However, we report six experiments on children (N = 480) and adults (N = 211) showing that this principle may not apply for actions

Free will is often appraised as a necessary input to for holding others morally or legally responsible for misdeeds. Recently, however, Clark and colleagues (2014) argued for the opposite causal relationship. They assert that moral judgments and the desire to punish motivate people's belief in free will. Three replication experiments (Studies 1-2b) attempt to reproduce these findings. Additionally

Adults titrate the degree of physical effort they are willing to expend according to the magnitude of reward they expect to obtain, a process guided by incentive motivation. However, it remains unclear whether adolescents, who are undergoing normative developmental changes in cognitive and reward processing, translate incentive motivation into action in a way that is similarly tuned to reward value

How do people mentally represent distinct interpersonal threats? Across human history, interpersonal threats such as infectious disease and violence have posed powerful selection pressures. Such pressures selected for psychological systems that help identify and reduce threats posed by other people. In the case of infectious disease, psychology researchers have found that such systems respond to a

The way we process rewarding stimuli is widely held to play a key role in normal and abnormal behavior. Biased processing of food-arguably the most primal form of reward-has been strongly implicated in the obesity crisis. Paradoxically, however, existing evidence suggests that both too much and too little attention can potentially lead to overeating. Here we sought to explain this contradiction within

The literature on human delay discounting behavior is dominated by experimental paradigms, which do not impose actual delays. Given that waiting may be aversive even on short timescales, we present a novel delay discounting paradigm to study differences in delay discounting behavior either when real waiting is involved, or not. This paradigm retains the fundamental trade-off between rewards received

Several previous studies reported relationships between speed of information processing as measured with the drift parameter of the diffusion model (Ratcliff, 1978) and general intelligence. Most of these studies utilized only few tasks and none of them used more complex tasks. In contrast, our study (N = 125) was based on a large battery of 18 different response time tasks that varied both in content

Our interactions with the world are guided by our understanding of objects' physical properties. When packing groceries, we place fragile items on top of more durable ones and position sharp corners so they will not puncture the bags. However, physical properties are not always readily observable, and we often must rely on our knowledge of attributes such as weight, hardness, and slipperiness to guide

Two experiments and 2 field studies examine how college students' perceptions of their science, technology, engineering, and mathematics (STEM) professors' mindset beliefs about the fixedness or malleability of intelligence predict students' anticipated and actual psychological experiences and performance in their STEM classes, as well as their engagement and interest in STEM more broadly. In Studies

The current research examined the interpersonal dynamics of emotion regulation in a stressful collaborative context. Little is known about how regulating one's own stress responses impacts teammates. In this article, we propose that individual efforts to regulate emotions can impact teammates for the better. We tested hypotheses arising from this claim using a dyadic experiment (N = 266) that assessed

Social attention is crucial for efficient social interactions and adaptive functioning in humans. However, whether this indispensable ability is unique and qualitatively distinct from nonsocial attention remains equivocal. Using the visual adaptation technique in conjunction with a modified central cueing paradigm, the current study investigated the specificity of social attention. Results revealed

Correlational studies have demonstrated detrimental effects of exposure to a mismatch between a nonstandard dialect at home and a mainstream variety at school on children's literacy skills. However, dialect exposure often is confounded with reduced home literacy, negative teacher expectation, and more limited educational opportunities. To provide proof of concept for a possible causal relationship

Visual processing is limited: we cannot exhaustively analyze every object in a scene in a brief glance. However, ensemble perception affords the visual system a rapid shortcut to efficiently evaluate multiple objects. Ensemble processing has been widely tested across basic features. However, ensemble perception could be especially important and valuable for processes that are normally thought to require

Incidental features of a stimulus can increase how easily it is processed, which can then increase confidence in task performance. Here, we examine the impact of fluency stemming from procedural features embedded in a task rather than in the features of a stimulus. We propose that manipulating the consistency of procedural features over a series of stimuli can produce procedural fluency, a metacognitive

The human brain may use recent sensory experience to create sensory templates that are then compared to incoming sensory input, that is, "knowing what to listen for." This can lead to greater perceptual sensitivity, as long as the relevant properties of the target stimulus can be reliably estimated from past sensory experiences. Echolocation is an auditory skill probably best understood in bats, but

In the current article, we test the prediction that an initial bias favoring 1 of 2 equally rewarding options-either based on a genuine contingency or a pseudocontingency in a small sample of initial observations-can survive over an extended period of further sampling from both options, when the reward structure fosters exploitation. Specifically, we argue and demonstrate that in reward-rich environments

A core issue in psycholinguistic research is what the online processes are by which we combine language input and our background knowledge to construct the meaning of a message. We investigate this issue in the context of reading. To build a coherent and correct mental representation of a text readers monitor incoming information for consistency with the preceding text and with their background knowledge

Previous studies suggested that the 2016 presidential elections gave rise to pathological levels of election-related distress in liberal Americans; however, it has also been suggested that the public discourse and the professional discourse have increasingly overgeneralized concepts of trauma and psychopathology. In light of this, in the current research, we utilized an array of big data measures and

Selective amnesia for previously established memories can be induced by administering drugs that impair protein synthesis shortly after memory reactivation. Competing theoretical accounts attribute this selective post-retrieval amnesia to drug-induced engram degradation (reconsolidation blockade) or to incorporation of sensory features of the reactivation experience into the memory representation,

Does spatial language contribute to the growth of preschool children's spatial skills? Four-year-old children (N = 50) were randomly assigned to a play-only (n = 24) or a spatial-language and play condition (n = 26). Their mental rotation and spatial vocabulary were assessed at baseline and several days after 5 play sessions. Children in the spatial-language condition scored higher at posttest on a
