Theories of autobiographical memory distinguish between involuntary and voluntary retrieval as a consequence of conscious intention (i.e., wanting to remember). Another distinction can be made between direct and generative retrieval, which reflects the effort involved (i.e., trying to remember). However, it is unclear how intention and effort inter...

Involuntary autobiographical memories come to mind effortlessly and unintended, but the mechanisms of their retrieval are not fully understood. We hypothesize that involuntary retrieval depends on memories that are highly accessible (e.g., intense, unusual, recent, rehearsed), while the elaborate search that characterizes voluntary retrieval also p...

Recent studies on involuntary autobiographical memories (IAMs) in daily life have shown that they are most frequently reported during daily routines (e.g. while ironing). Such studies have suggested that reporting IAMs may be influenced by the level of the ongoing task demands and availability of cognitive resources. In two studies, we investigated...

In everyday life, involuntary thoughts about future plans and events occur as often as involuntary thoughts about the past. However, compared to involuntary autobiographical memories (IAMs), such episodic involuntary future thoughts (IFTs) have become a focus of study only recently. The aim of the present investigation was to examine why we are not...

Semantic priming has been studied for nearly 50 years across various experimental manipulations and theoretical frameworks. Although previous studies provide insight into the cognitive underpinnings of semantic representations, they have suffered from small sample sizes and a lack of linguistic and cultural diversity. In this Registered Report, we...

Ideal partner preferences (i.e., ratings of the desirability of attributes like attractiveness or intelligence) are the source of numerous foundational findings in the interdisciplinary literature on human mating. Recently, research on the predictive validity of ideal partner preference matching (i.e., Do people positively evaluate partners who mat...

According to the justified true belief (JTB) account of knowledge, people can truly know something only if they have a belief that is both justified and true (i.e., knowledge is JTB). This account was challenged by Gettier, who argued that JTB does not explain knowledge attributions in certain situations, later called “Gettier-type cases,” wherein...

In their commentary on Hall et al., Buckwalter and Friedman (2024) claimed that the replication should have been interpreted as successful, argued that the researchers’ conclusions were incorrect, and implied that the replication effort was misguided. As a subset of contributors to the Hall et al. replication, we appreciate the opportunity to respo...

Though people usually imagine the typical person as a man rather than a woman, the effect is mixed for racial groups and understudied among traditionally male social groups (e.g., police and criminals) and non-U.S. populations. Results from a survey (N > 5000) collected via a globally distributed laboratory network in over 40 regions demonstrated t...

Cultural logic is a set of cultural scripts and patterns organized around a central theme.

In their replication of Turri et al. (2015; Experiment 1), Hall et al. (2024) identified a key condition difference that was not observed in the original experiment. In their commentary, Buckwalter and Friedman (2024) posited that the evidence presented by Hall et al. should be interpreted as fully replicating Turri et al. While Hall et al. may hav...

The memory conformity effect occurs when people witness a given incident (e.g. a crime) then talk to each other about it, and the statement of one person affects the memory account of the other person with respect to this incident. The aim of this article is to improve the quality of witness testimony by verifying the effectiveness of three methods...

The paper presents a comprehensive guide for researchers investigating mind-wandering and related phenomena such as involuntary past and future thinking. Examining such spontaneous cognitions presents a challenge requiring not only the use of appropriate laboratory-based procedures, but also the coding of complex qualitative data. This guide outlin...

Background: Multicultural organizations in the era of globalization require intercultural leadership skills. Healthcare, as a sector serving diverse populations, necessitates culturally sensitive staff. Intercultural nurse education should start in undergraduate education. A tailored approach is needed, especially in the context of Poland's refugee...

The paper presents the memory conformity effect phenomenon, which involves the inclusion in memory accounts concerning a particular event (original information) of incorrect information (misinformation) that a witness has obtained as a result of another witness's account of the same event. The research had two goals: (1) to verify the existence of...

The construct of personal control is crucial for understanding a variety of human behaviors. Perceived lack of control affects performance and psychological well-being in diverse contexts-educational, organizational, clinical, and social. Thus, it is important to know to what extent we can rely on the established experimental manipulations of (lack...

Introduction The memory conformity effect occurs when people witness a given incident and then talk to each other about it, and the statement of one person affects the memory account of another person with respect to that incident. The main objectives of this experiment were (1) to examine the effectiveness of a modified version of the MORI-v techn...

Understanding the attitudes of medical staff contributes to shaping a culture of safety in health care. The aim of this study was the measurement of attitudes of nurses and midwives towards reporting clinical adverse events. Various research tools were used, including the Reporting of Clinical Adverse Events Scale (RoCAES; Polish: P-RoCAES), the Ju...

The planning of sample size for research studies often focuses on obtaining a significant result given a specified level of power, significance, and an anticipated effect size. This planning requires prior knowledge of the study design and a statistical analysis to calculate the proposed sample size. However, there may not be one specific testable...

In the era of higher education institutions' internatio-nalisation, international student mobility is viewed as a crucial educational tool for enhancing the cross-cultural competence of learners. This paper aims to present research findings on the development of cross-cultural competence (skills, knowledge, and attitudes) among students participati...

Recovered memories of trauma are memories of traumatic events experienced generally during childhood, but of which the persons were unaware until they retrieved it. Legal decisions are sometimes based on such recovered memories, the validity of which is often questioned. Yet, people can recover genuine traumatic memories of childhood abuse. In this...

Involuntary autobiographical memories (IAMs) and déjà vu are phenomena that occur spontaneously in daily life. IAMs are recollections of the personal past, whereas déjà vu is defined as an experience in which the person feels familiarity at the same time as knowing that the familiarity is false. We present and discuss the idea that both IAMs and dé...

In our target article, we presented the idea that involuntary autobiographical memories (IAMs) and déjà vu may both be based on the same retrieval processes. Our core claim was thus straightforward: Both can be described as “involuntary” or spontaneous cognitions, where IAMs deliver content and déjà vu delivers only the feeling of retrieval. Our pr...

Mental simulation theories of language comprehension propose that people automatically create mental representations of objects mentioned in sentences. Mental representation is often measured with the sentence-picture verification task, wherein participants first read a sentence that implies the object property (i.e., shape and orientation). Partic...

The manuscript describes an experimental investigation of a technique that might reduce memory conformity: the reinforced self‐affirmation procedure (RSA). While previous studies have already demonstrated the RSA's effectiveness in reducing other memory distortions (e.g., the misinformation effect and interrogative suggestibility), this has not bee...

People can remember experiences from their past, either deliberately or spontaneously-that is, memories can be voluntarily or involuntarily retrieved. People tend to report that their voluntary and involuntary memories have different properties. But people's reports about their mental phenomena can be open to bias or mistaken, shaped in part by the...

In response to the COVID-19 pandemic, the Psychological Science Accelerator coordinated three large-scale psychological studies to examine the effects of loss-gain framing, cognitive reappraisals, and autonomy framing manipulations on behavioral intentions and affective measures. The data collected (April to October 2020) included specific measures...

Recently, research on the predictive validity of ideal partner preference-matching (i.e., do people positively evaluate partners who mat...

In this article we review the literature on the phenomenology of retrieval from the personal past, and propose a framework for understanding how epistemic feelings and metacognitive reflections guide the retrieval of representations of past events in the Self Memory System. Our focus is on an overlooked aspect of autobiographical memory, the phenom...

Voluntary isolation is one of the most effective methods for individuals to help prevent the transmission of diseases such as COVID-19. Understanding why people leave their homes when advised not to do so and identifying what contextual factors predict this non-compliant behavior is essential for policymakers and public health officials. To provide...

General Audience Summary The COVID-19 pandemic was a global phenomenon; people in countries across the world experienced the pandemic similarly, but did it affect the way we perceived the past and future? This study reports whether and how people experienced spontaneous thoughts about the past and future of the pandemic—that is, images of the past...

Following theories of emotional embodiment, the facial feedback hypothesis suggests that individuals’ subjective experiences of emotion are influenced by their facial expressions. However, evidence for this hypothesis has been mixed. We thus formed a global adversarial collaboration and carried out a preregistered, multicentre study designed to spe...

The COVID-19 pandemic (and its aftermath) highlights a critical need to communicate health information effectively to the global public. Given that subtle differences in information framing can have meaningful effects on behavior, behavioral science research highlights a pressing question: Is it more effective to frame COVID-19 health messages in t...

The COVID-19 pandemic has increased negative emotions and decreased positive emotions globally. Left unchecked, these emotional changes might have a wide array of adverse impacts. To reduce negative emotions and increase positive emotions, we tested the effectiveness of reappraisal, an emotion-regulation strategy that modifies how one thinks about...

The present study focused on involuntary thoughts about personal past events (i.e., involuntary autobiographical memories; IAMs), and involuntary thoughts about future events and plans (i.e., involuntary future thoughts; IFTs). The frequency of these involuntary thoughts is influenced by cognitive demands of ongoing activities, but the exact underl...

The COVID-19 pandemic created a unique set of circumstances in which to investigate collective memory and future simulations of events reported during the onset of a potentially historic event. Between early April and late June 2020, we asked over 4,000 individuals from 15 countries across four continents to report on remarkable (a) national and (b...

This book brings together dozens of the world’s leading scholars in memory studies to explore national memory in an age of populism. Drawing on disciplines ranging from cognitive science to history, these scholars address issues such as how memory is tied to individual and collective identity, how national pasts create political presents, and how a...

The provided dataset represents the performance of adult individuals in three experimental tasks measuring cognitive inhibition: the Stroop task; the SART task and the Eriksen Flanker task. All tasks were initially completed in a web setting (online) by 485 individuals. Additionally, randomly selected participants completed all these tasks one more...

Significance Communicating in ways that motivate engagement in social distancing remains a critical global public health priority during the COVID-19 pandemic. This study tested motivational qualities of messages about social distancing (those that promoted choice and agency vs. those that were forceful and shaming) in 25,718 people in 89 countries...

The study of moral judgements often centres on moral dilemmas in which options consistent with deontological perspectives (that is, emphasizing rules, individual rights and duties) are in conflict with options consistent with utilitarian judgements (that is, following the greater good based on consequences). Greene et al. (2009) showed that psychol...

It is assumed that the difference between voluntary and involuntary autobiographical memories lies in the intentionality to retrieve a memory assigned by the experimenter. Memories that are retrieved when people are instructed to do so in response to cues are considered voluntary (VAMs), those that pop up spontaneously are considered involuntary (I...

Objectives While voluntary memories are intended and expected, involuntary memories are retrieved with no intention and are usually unexpected (when one is not waiting for a memory). The present study investigates the effects of retrieval intentionality ( wanting to retrieve a memory) and monitoring processes ( expecting a memory to appear) on the...

Semantic priming has been studied for nearly 50 years across various experimental manipulations and theoretical frameworks. These studies provide insight into the cognitive underpinnings of semantic representations in both healthy and clinical populations; however, they have suffered from several issues including generally low sample sizes and a la...

Background: There are more and more foreigners in Poland who become clients of the Polish healthcare system. They use, among others, emergency medical services provided by healthcare professionals: doctors, nurses, and paramedics. Skillful care for culturally different patients requires cultural competencies and cultural intelligence to ensure goo...

In everyday life, people often experience involuntary thoughts about their personal past and future events in response to incidental cues in the environment. Yet, despite the abundance of such cues, our consciousness is not constantly flooded by these involuntary autobiographical memories (IAMs) and involuntary future thoughts (IFTs). The main goal...

The paper presents the memory conformity effect phenomenon, which assumes that information about the same event that a witness acquires from another witness (misinformation) is incorporated into the first witness’ memory of the event (original information). The study has two goals: (1) to verify the existence of people with the memory conformity ef...

In the present paper, we provide a protocol for experimentally measuring and calculating individual inhibitory control capacity index in adult participants in an online Inquisit-based setting. We believe that this method can serve other researchers in the standardized assessment of individual inhibitory control capacity that can be used in studies...

Background: Since 2012, education standards in medical faculties in Poland have allowed medical universities to introduce content related to multiculturalism. On the one hand, this creates a necessity to introduce new strategies, forms, and techniques of education aimed at the development of knowledge, skills, and attitudes in terms of multicultura...

Theories of autobiographical memory distinguish between involuntary and voluntary memories. While involuntary memories are retrieved with no conscious intention and are therefore unexpected, voluntary memories are both intended and expected. Recent research has shown that participants sometimes classify their memories as either involuntary or volun...

In situations of cognitive overload, the role of a metacognitive decision to stop learning is of utmost importance. We investigated how young and older adults decide to stop learning as a strategy for maximizing memory performance when they face to-be-learned material exceeding their memory capability. People may decide to stop learning for two mai...

Over the past 10 years, Oosterhof and Todorov’s valence–dominance model has emerged as the most prominent account of how people evaluate faces on social dimensions. In this model, two dimensions (valence and dominance) underpin social judgements of faces. Because this model has primarily been developed and tested in Western regions, it is unclear w...

Tearful crying is a ubiquitous and likely uniquely human phenomenon. The persistence of this behavior throughout adulthood has fascinated and puzzled many researchers. Scholars have argued that emotional tears serve an attachment function: Tears are thought to act as a social glue by triggering social support intentions. Initial experimental studie...

While previous studies have already demonstrated the RSA’s effectiveness in reducing other memory distortions (e.g., the misinformation effect, interrogative suggestibility), this has n...

Introduction. The growing cultural diversity of Polish society creates new challenges for people who, in their professional activities, deal with culturally divergent people. Therefore, on the one hand, there is an urgent need for education and development in cross-cultural competences; on the other hand, there is a need to measure these competence...

The facial feedback hypothesis suggests that an individual’s subjective experience of emotion is influenced by their facial expressions. Researchers, however, currently face conflicting narratives about whether this hypothesis is valid. A large replication effort consistently failed to replicate a seminal demonstration of the facial feedback hypoth...

The present study investigated autobiographical memories of school. While previous works have shown that most memories relating to school are social as opposed to academic, there are still strong theoretical arguments for the presumed prevalence of educationally oriented memories from at least some parts of the school period. The goal of the study...

While involuntary memories are retrieved with no intention and are usually unexpected (when one is not waiting for a memory to arise), voluntary memories are intended and expected (when one is searching and waiting for a memory to arise).

Much research on moral judgment is centered on moral dilemmas in which deontological perspectives (i.e., emphasizing rules, individual rights and duties) are in conflict with utilitarian judgements (i.e., following the greater good defined through consequences). A central finding of this field Greene et al. showed that psychological and situational...

The observation that exerting self-control in an initial task impairs subsequent self-control performance in a following task has been used to explain a wide range of phenomena. If evidence for this “ego-depletion” effect was initially believed to be strong, it is now questioned. Recent meta-analyses indicated that this effect was sensitive to publ...

Background Due to changes in Polish society resulting from a significant inflow of immigrants to Poland, the need to develop the cultural competences of various professional groups who have contact with immigrants in their work has increased. These groups should include healthcare professionals, especially because of the significant increase in the...
