The influence of temporal distance on justice and care morality
- 2010
-
In: Scandinavian Journal of Psychology. - : Wiley. - 1467-9450 .- 0036-5564. ; 51, s. 46-55
-
Journal article (peer-reviewed)abstract
- The primary goal of this study was to examine whether changes in the temporal distance of a moral dilemma affect how it is perceived and subsequently resolved. Based on Construal Level Theory (Trope & Liberman, 2003), it was predicted that the relative weight of abstract justice features should increase and the relative weight of concrete care features should decrease with temporal distance. The results showed that females became increasingly justice-oriented with greater temporal distance. However, this was not the case for males who were unaffected by temporal distance. This interaction was conceptually replicated in a follow-up experiment in which abstraction was manipulated directly by a mindset manipulation. The present results suggest that temporal distance is a contextual factor that can alter the extent to which moral judgments and reasoning are based on justice and care, although this effect seems to be moderated by gender.

Developing Theoretical and Empirical Definitions of Safety Problems in Driving Suitable for Active Safety Function Evaluation
- 2009
-
Licentiate thesis (other academic/artistic)abstract
- In passive safety, the requirement specifications used for evaluation of protective functions are both standardised and specified at a high level of detail regarding evaluation scenario definition, performance metrics and pass/fail criteria. For active safety, while several propositions for evaluation scenarios have been made, neither these, nor performance metrics and pass/fail criteria have yet reached a similar level of detail and standardisation. The objective of this thesis is to address two underlying reasons for this difference. One is theoretical in nature. On a general level, a set of principles and concepts which capture the fundamental ideas of a field of science can be called a conceptual framework. For active safety function evaluation, such a framework is currently lacking. To address this issue, a conceptual framework called Situational control was developed. The framework integrates fundamental ideas relevant for active safety function evaluation into a holistic and practically applicable picture. Its applicability was demonstrated by applying it in the context of writing and implementing requirement specifications for active safety function evaluation.The second reason is of empirical character. To evaluate the extent to which active safety functions prevent and/or mitigate crashes, it is essential to characterize the sequence of events which leads to collisions in a way which includes information on causal factors. To do this, data from official databases (macroscopic data), and in-depth case studies is often used. Macroscopic data is usually statistically representative but has limited information on why crashes happen, while the opposite is true of case studies. Using the two in combination would therefore seem ideal. However, the principles for connecting them are far from clear and current approaches suffer inherent weaknesses. To address this issue, a generalization methodology which links information in case studies to macroscopic crash types, in a way which covers not only context but also causation similarity, was developed. The feasibility of the methodology was tested through application on three sets of intersection crash data. Results indicate that the methodology was sufficiently successful to warrant further exploration with larger data sets.

Effects of communication with non-witnesses on eyewitnesses' recall correctness and meta-cognitive realism
- 2011
-
In: Applied Cognitive Psychology. - Chichester : John Wiley & Sons. - 0888-4080 .- 1099-0720. ; 25:5, s. 782-791
-
Journal article (peer-reviewed)abstract
- In forensic contexts it is common that witnesses retell and discuss the experienced event many times. It is of forensic importance to understand how this influences memory and meta-memory. Eighty-nine participants viewed a short film and were assigned to one of four conditions: (1) Laboratory discussion (five discussions of the event with a confederate), (2) Family discussion (five discussions of the event with a family member), (3) Retell (five retellings of the event) and (4) Control. Three weeks later participants gave an open free recall, and then 3 days later confidence judged the recalled information. The results showed significant differences between the four conditions on number of correct items, incorrect items, accuracy, confidence and calibration. The results suggest that discussion of an experienced event may reduce some of the beneficial memory and meta-memory effects caused by mere retelling, but may have no great negative effects compared to a control condition.

Review and assessment of self-reports of travel-related emotional wellbeing
- 2020
-
In: Journal of Transport & Health. - : Elsevier. - 2214-1405 .- 2214-1413. ; 17
-
Journal article (peer-reviewed)abstract
- Introduction: Travel behavior research has only started to address how travel affects emotional wellbeing. The development of measurement methods is an important goal of this research.Methods: A review and assessment of methods of measuring travel-related emotional wellbeing is presented guided by a conceptual framework specifying what is measured (cognitive evaluations, emotional responses, or moods), the way it is measured (proactively, instantaneously, or retrospectively), and when it is measured (before, during, or after travel). Anticipated, current, residual and recalled moods are the objects of the measurement. Only studies of commuting or other types of daily travel are addressed.Results: We find that no research has measured anticipated moods, some research has measured current moods before, after and during travel, and most research has measured recalled moods.Conclusions: The most valid and reliable method is to measure current mood instantaneously at several points in time, before, during, and after travel. A measure of emotional wellbeing can then be obtained by objective aggregation. An approximate more feasible method is to retrospectively measure recalled moods for a given specified time period that may not only include travel. The available methods for measuring recalled moods have acceptable psychometric properties but research is needed to validate these methods by comparing the results to an objective aggregation of instantaneous measures of current mood at different points in time.

Observing as an Essential Facet of Mindfulness : A Comparison of FFMQ Patterns in Meditating and Non-Meditating Individuals
- 2013
-
In: Mindfulness. - : Springer. - 1868-8527 .- 1868-8535. ; 4:3, s. 203-212
-
Journal article (peer-reviewed)abstract
- One of the most comprehensive measures of mindfulness is the Five Facet Mindfulness Questionnaire (FFMQ) with five factors-Observing, Describing, Acting with awareness, Non-judging, and Non-reactivity. Hierarchical confirmatory factor analyses, however, have suggested that only four of the FFMQ factors (i.e. all except Observing) were components of "an overall mindfulness construct"-which is puzzling because Observing represents a core aspect of all definitions of mindfulness. The purpose of the present study was to approach this problem by a person-oriented approach, focusing on patterns on the FFMQ scales, rather than linear associations between them. Data on the FFMQ were collected on 817 individuals. Cluster analysis according to the LICUR procedure was used to group these participants in 13 clusters, according to their profiles of scores on the five FFMQ scales. Of the participants, 325 were categorized as meditators and 317 as non-meditators. To test hypotheses about the relation between Observing and mindfulness (which we assumed should be higher among meditators), the meditators/non-meditators categorization was cross-tabulated with the FFMQ clusters. The results showed that all clusters in which meditators were over-represented had high scores on Observing, and all clusters in which meditators were under-represented had low scores on Observing-which supports the hypothesis that mindfulness is related to high levels of Observing. The relationship between Observing and Non-judging, however, was found to be more complex than expected. The results are discussed in terms of mindfulness seen as a multidimensional skill, which may develop differently in various subgroups of individuals.

An empirical investigation of attitudes towards daily commuting transportation: the impacts of travel satisfaction, driving habits and social desirability.
- 2018
-
In: The 29th International Congress of Applied Psychology, June 26-30, Montréal, Canada.
-
Conference paper (other academic/artistic)abstract
- Background/Rational Every day people decide how to travel to their out-of-home activities. What is important for them when choosing the mode of transportation? Are those things predictors of attitudes towards modes of transportation along with driving habits and satisfaction with daily travel? Does being more or less satisfied affect people’s attitudes? Method A survey was mailed to a sample of 3,000 Swedish residents in rural, semi-rural and urban areas. The questionnaire consisted of four sections: driving habits, satisfaction, important aspects when choosing mode of daily commuting and socio-demographics measurements. Results Factor analysis was conducted regarding “satisfaction with daily commuting”, “important aspects for mode choice of commuting” and “driving habits” (KMO = .74; .76; 79, respectively). The retained factors were used in multiple regressions analyses as predictors of attitudes towards car, public transport and bike (R2 = .32; .11; .16, respectively). Conclusions “Driving habits” was the main predictor for attitudes towards car while “socially desirable aspects” was the most important factor to predict attitudes towards public transport and bike. Living in big cities negatively affected attitudes toward car and satisfaction with daily commuting was a minor predictor for all modes of transportation. Action/Impact Attitudes towards modes of commuting are predicted by people’s habits and what they value as important when commuting. Knowing what they value when choosing modes of transportation gives support to implement accurate and effective interventions, policies and new services that promote sustainability in transportation.

Policy is not enough : the influence of the gendered workplace on fathers' use of parental leave in Sweden
- 2019
-
In: Community, Work and Family. - : Taylor & Francis Group. - 1366-8803 .- 1469-3615. ; 22:1, s. 58-76
-
Journal article (peer-reviewed)abstract
- Paid parental leave for fathers is a promising social policy tool for degendering the division of labor for childcare. Swedish fathers have had the right to paid parental leave since 1974, but they take only one-fourth of leave days parents take. There are strong cultural norms supporting involved fatherhood, so couples typically want to share leave more than they do. This article explores how workplaces can constrain Swedish fathers' use of state leave policy, in ways that fathers can take for granted, a topic that has received less attention than individual or family-related obstacles. Based on interviews with 56 employees in five large private companies, we found that masculine workplace norms can make it difficult for fathers to choose to take much leave, while aspects of traditional workplace structure building on these norms can negatively affect fathers' capabilities of taking much leave. Workplace culture and structure seemed to be based on assumptions that the ideal worker should prioritize work and has limited caregiving responsibilities, setting limits to fathers' ability to share leave with mothers. Gender theorists suggest such assumptions persist because of male dominance at the workplace and the endurance of gendered assumptions about the roles of men and women.

Human physiological benefits of viewing nature: EEG responses to exact and statistical fractal patterns.
- 2015
-
In: Nonlinear Dynamics, Psychology, and Life Sciences. - 1090-0578. ; 19:1, s. 1-12
-
Journal article (peer-reviewed)abstract
- Psychological and physiological benefits of viewing nature have been extensively studied for some time. More recently it has been suggested that some of these positive effects can be explained by nature's fractal properties. Virtually all studies on human responses to fractals have used stimuli that represent the specific form of fractal geometry found in nature, i.e. statistical fractals, as opposed to fractal patterns which repeat exactly at different scales. This raises the question of whether human responses like preference and relaxation are being driven by fractal geometry in general or by the specific form of fractal geometry found in nature. In this study we consider both types of fractals (statistical and exact) and morph one type into the other. Based on the Koch curve, nine visual stimuli were produced in which curves of three different fractal dimensions evolve gradually from an exact to a statistical fractal. The patterns were shown for one minute each to thirty-five subjects while qEEG was continuously recorded. The results showed that the responses to statistical and exact fractals differ, and that the natural form of the fractal is important for inducing alpha responses, an indicator of a wakefully relaxed state and internalized attention.

The impact of driver sleepiness on fixation-related brain potentials
- 2020
-
In: Journal of Sleep Research. - : Wiley. - 0962-1105 .- 1365-2869. ; 29:5
-
Journal article (peer-reviewed)abstract
- The effects of driver sleepiness are often quantified as deteriorated driving performance, increased blink durations and high levels of subjective sleepiness. Driver sleepiness has also been associated with increasing levels of electroencephalogram (EEG) power, especially in the alpha range. The present exploratory study investigated a new measure of driver sleepiness, the EEG fixation-related lambda response. Thirty young male drivers (23.6 +/- 1.7 years old) participated in a driving simulator experiment in which they drove on rural and suburban roads in simulated daylight versus darkness during both the daytime (full sleep) and night-time (sleep deprived). The results show lower lambda responses during night driving and with longer time on task, indicating that sleep deprivation and time on task cause a general decrement in cortical responsiveness to incoming visual stimuli. Levels of subjective sleepiness and line crossings were higher under the same conditions. Furthermore, results of a linear mixed-effects model showed that low lambda responses are associated with high subjective sleepiness and more line crossings. We suggest that the fixation-related lambda response can be used to investigate driving impairment induced by sleep deprivation while driving and that, after further refinement, it may be useful as an objective measure of driver sleepiness.

Cultivating Compassion and Reducing Stress and Mental Ill-Health in Employees : A Randomized Controlled Study
- 2022
-
In: Frontiers in Psychology. - : Frontiers Media SA. - 1664-1078. ; 12
-
Journal article (peer-reviewed)abstract
- Stress and mental ill-health carry considerable costs for both individuals and organizations. Although interventions targeting compassion and self-compassion have been shown to reduce stress and benefit mental health, related research in organizational settings is limited. We investigated the effects of a 6-week psychological intervention utilizing compassion training on stress, mental health, and self-compassion. Forty-nine employees of two organizations were randomly assigned to either the intervention (n = 25) or a physical exercise control condition (n = 24). Multilevel growth models showed that stress (p = 0.04) and mental ill-health (p = 0.02) decreased over 3 months in both groups (pre-intervention to follow-up: Cohen’s d = −0.46 and d = 0.33, respectively), while self-compassion only increased in the intervention group (p = 0.03, between group d = 0.53). There were no significant effects on life satisfaction in any of the groups (p > 0.53). The findings show promising results regarding the ability of compassion training within organizations to decrease stress and mental ill-health and increase self-compassion.

Effects of Task Demands on Olfactory, Auditory, and Visual Event-Related Potentials Suggest Similar Top-Down Modulation Across Senses
- 2018
-
In: Chemical Senses. - : Oxford University Press (OUP). - 0379-864X .- 1464-3553. ; 43:2, s. 129-134
-
Journal article (peer-reviewed)abstract
- A widely held view is that top-down modulation of sensory information relies on an amodal control network that acts through the thalamus to regulate incoming signals. Olfaction lacks a direct thalamic projection, which suggests that it may differ from other modalities in this regard. We investigated the late positive complex (LPC) amplitudes of event-related potentials (ERP) from 28 participants, elicited by intensity-matched olfactory, auditory and visual stimuli, during a condition of focused attention, a neutral condition, and a condition in which stimuli were to be actively ignored. Amplitudes were largest during the attend condition, lowest during the ignore condition, with the neutral condition in between. A Bayesian analysis resulted in strong evidence for similar effects of task across sensory modalities. We conclude that olfaction, despite its unique neural projections, does not differ from audition and vision in terms of task-dependent neural modulation of the LPC.

Contest-based and norm-based interventions: (How) do they differ in attitudes, norms, and behaviors?
- 2019
-
In: Sustainability. - : MDPI AG. - 2071-1050. ; 11:2
-
Journal article (peer-reviewed)abstract
- Setting up a contest is a popular means to promote pro-environmental behaviors. Yet, research on contest-based interventions is scarce while norm-based interventions have gained much attention. In two field experiments, we randomly assigned 79 apartments to either a contest-based or a norm-based electricity conservation intervention and measured kWh usage for 2 and 4 weeks, respectively. Results from both studies showed that contest-based interventions promote intensive but short-lived electricity saving. In Study 1 apartments assigned to a norm-based intervention showed more stable electricity saving (low intensity and long-lasting). Study 2 did not replicate this finding, but supported that participants in the norm-based intervention also engaged in non-targeted behaviors. These results emphasize the importance of identifying how different intervention techniques may activate different goals, framing both how people think about and act upon targeted pro-environmental behaviors.

Experiencing a severe weather event increases concern about climate change
- 2019
-
In: Frontiers in Psychology. - : Frontiers Media SA. - 1664-1078. ; 10
-
Journal article (peer-reviewed)abstract
- Climate change is primarily driven by human-caused greenhouse gas (GHG) emissions, and may therefore be mitigated by changes to human behavior (Clayton et al., 2015; IPCC, 2018). Despite efforts to raise awareness and concern about climate change, GHG emissions continue to rise (IPCC, 2018). Climate change seems to be at odds with the immediate, present threats to which humans are adapted to cope (Gifford et al., 2009; Schultz, 2014; van Vugt et al., 2014). In contrast to immediate dangers, climate change is typically abstract, large scale, slow and often unrelated to the welfare of our daily lives (e.g., Ornstein and Ehrlich, 1989; Gifford, 2011). But there are moments when the consequences of climate change are readily apparent, such as extreme weather events. In the current paper, we examine the impact of personal experience with an extreme weather event, and the impact of this experience on beliefs about climate change, and intentions to take actions that can help prepare for and mitigate the consequences of climate change.

Shift work and cognitive aging : A longitudinal study
- 2017

-
Journal article (peer-reviewed)abstract
- Objectives The few studies of shift work and late life cognitive functioning have yielded mixed findings. The aim of the present study is to estimate the association between shift-work experience and change in cognitive performance before and after retirement age among older adults who were gainfully employed.Methods Five hundred and ninety five participants with no dementia were followed up for a mean of 17.6 standard deviation (SD) 8.8 years from a Swedish population-based sample. Participants had self-reported information on any type of shift-work experience (ever/never) in 1984 and measures of cognitive performance (verbal, spatial, memory, processing speed, and general cognitive ability) from up to 9 waves of cognitive assessments during 1986–2012. Night work history (ever/never) from 1998–2002 was available from a subsample (N=320). Early adult cognitive test scores were available for 77 men.Results In latent growth curve modeling, there were no main effects of "any-type" or night shift work on the mean scores or rate of change in any of the cognitive domains. An interaction effect between any-type shift work and education on cognitive performance at retirement was noted. Lower-educated shift workers performed better on cognitive tests than lower-educated day workers at retirement. Sensitivity analyses, however, indicated that the interactions appeared to be driven by selection effects. Lower-educated day workers demonstrated poorer cognitive ability in early adulthood than lower-educated shift workers, who may have selected jobs entailing higher cognitive demand.Conclusion There was no difference in late-life cognitive aging between individuals with a history of working shifts compared to those who had typical day work schedules during midlife.

Adolescent gaming and parent-child emotional closeness : bivariate relationships in a longitudinal perspective
- 2024
-
In: Current Psychology. - 1046-1310 .- 1936-4733. ; 43, s. 19655-19665
-
Journal article (peer-reviewed)abstract
- The aim of this study was to add knowledge of the longitudinal associations between gaming and emotional closeness between parents and their children. We hypothesized that parent–child emotional closeness was linked to less gaming activity over time and that more gaming activity was linked to less parent–child emotional closeness over time. We also tested the moderating effect of child gender on these anticipated links. This study involved a sample of Swedish adolescents, spanning the developmental years from age 12.5 to 17, and included data from two time points (T1; year 2013 and T2; years 2017/2018) with N = 782 participants (T1 Mage = 12.10, SD = 0.40; 49.6% girls). Utilizing a series of Cross-Lagged Panel Models, we found that emotional closeness to both mother and father predicted less time spent on gaming over time. More time spent on gaming predicted less emotional closeness to mother over time. Additionally, gaming activity among girls was specifically related to less emotional closeness to their father over time. Strengthening parent–child relationships and emotional bonds may be crucial in safeguarding adolescents from developing habits of excessive gaming that could potentially pose problems for their psychosocial development.

Screen time and addictive use of gaming and social media in relation to health outcomes
- 2023
-
In: Frontiers in Psychology. - 1664-1078. ; 14
-
Journal article (peer-reviewed)abstract
- Introduction: This study examined associations between screen time and addictive use (i.e., heavy involvement and negative consequences) of gaming and social media, and their independent effects on health outcomes. Methods: Survey data were collected from 2,265 participants (mean age = 21.57). Internet Gaming Disorder (IGD) and Social Media Disorder (SMD) were measured with the Gaming and Social Media Questionnaire (GSMQ-9), with separate measures for heavy involvement and negative consequences. Screen time was measured by weekly hours of gaming and social media. Assessed health outcomes were psychological problems, low self-concept, social problems, sleep problems, and sleep time. Results: Screen time and addictive use were significantly associated for both gaming and social media, with associations being stronger for symptoms of heavy involvement compared to symptoms of negative consequences. However, despite significant associations, a substantial proportion of the participants with a high screen time did not meet any or just one symptom of addiction. More importantly, it was primarily negative consequences that had independent effects on health outcomes, except for sleep. High levels of heavy involvement in gaming, were even related to lower, not higher, levels of psychological problems. Conclusion: The present findings study show that screen time is a poor indicator of addictive use of gaming and social media. Given that it was primarily negative consequences of gaming or social media that had effects on health outcomes, our study also emphasizes the need to distinguish between different types of addictive use and to further examine the diagnostic validity of the nine IGD symptom criteria.

Neighborhood conditions in a Swedish context - Two studies of reliability and validity of virtual systematic social observation using Google Street View
- 2023
-
In: Frontiers in Psychology. - : Frontiers Media SA. - 1664-1078. ; 14
-
Journal article (peer-reviewed)abstract
- Introduction: The goal of these studies was to investigate the reliability and validity of virtual systematic social observation (virtual SSO) using Google Street View in a Swedish neighborhood context.Methods: This was accomplished in two studies. Study 1 focused on interrater reliability and construct validity, comparing ratings conducted in-person to those done using Google Street View, across 24 study sites within four postal code areas. Study 2 focused on criterion validity of virtual SSO in terms of neighborhoods with low versus high income levels, including 133 study sites within 22 postal code areas in a large Swedish city. In both studies, assessment of the neighborhood context was conducted at each study site, using a protocol adapted to a Swedish context.Results: Scales for Physical Decay, Neighborhood Dangerousness, and Physical Disorder were found to be reliable, with adequate interrater reliability, high consistency across methods, and high internal consistency. In Study 2, significantly higher levels of observed Physical Decay, Neighborhood Dangerousness, and signs of garbage or litter were observed in postal codes areas (site data was aggregated to postal code level) with lower as compared to higher income levels.Discussion: We concluded that the scales within the virtual SSO with Google Street View protocol that were developed in this series of studies represents a reliable and valid measure of several key neighborhood contextual features. Implications for understanding the complex person-context interactions central to many theories of positive development among youth were discussed in relation to the study findings.

Higher- and lower-order personality traits and cluster subtypes in social anxiety disorder
- 2020
-
In: PLOS ONE. - : PUBLIC LIBRARY SCIENCE. - 1932-6203. ; 15:4
-
Journal article (peer-reviewed)abstract
- Social anxiety disorder (SAD) can come in different forms, presenting problems for diagnostic classification. Here, we examined personality traits in a large sample of patients (N = 265) diagnosed with SAD in comparison to healthy controls (N = 164) by use of the Revised NEO Personality Inventory (NEO-PI-R) and Karolinska Scales of Personality (KSP). In addition, we identified subtypes of SAD based on cluster analysis of the NEO-PI-R Big Five personality dimensions. Significant group differences in personality traits between patients and controls were noted on all Big Five dimensions except agreeableness. Group differences were further noted on most lower-order facets of NEO-PI-R, and nearly all KSP variables. A logistic regression analysis showed, however, that only neuroticism and extraversion remained significant independent predictors of patient/control group when controlling for the effects of the other Big Five dimensions. Also, only neuroticism and extraversion yielded large effect sizes when SAD patients were compared to Swedish normative data for the NEO-PI-R. A two-step cluster analysis resulted in three separate clusters labelled Prototypical (33%), Introvert-Conscientious (29%), and Instable-Open (38%) SAD. Individuals in the Prototypical cluster deviated most on the Big Five dimensions and they were at the most severe end in profile analyses of social anxiety, self-rated fear during public speaking, trait anxiety, and anxiety-related KSP variables. While additional studies are needed to determine if personality subtypes in SAD differ in etiological and treatment-related factors, the present results demonstrate considerable personality heterogeneity in socially anxious individuals, further underscoring that SAD is a multidimensional disorder.

Old and very old adults as witnesses: event memory and metamemory
- 2015
-
In: Psychology, Crime and Law. - 1477-2744 .- 1068-316X. ; 21:8, s. 764-775
-
Journal article (peer-reviewed)abstract
- Older people constitute an important category of eyewitnesses. Episodic memory performance in older persons is poorer than in younger adults, but little research has been made on older persons' metacognitive judgments. Since more persons of advanced age will likely be called upon as witnesses in coming years, it is critical to characterize this population's metacognitive abilities. We compared event memory metacognition in old adults (66-year-old, n = 74) to very old adults (87 or 90 years old, n = 55). Participants were tested on their memory of a film, using questions with two answer alternatives and the confidence in their answer. As expected, the very old group had a lower accuracy rate than the old group (d = 0.59). The very old group, however, monitored this impairment, since their over-/underconfidence and calibration did not differ from the old group but they displayed a poorer ability to separate correct from incorrect answers (discrimination ability). Possibly, the very old group was able to monitor the level of their over-/underconfidence because they applied general self-knowledge about their memory skills. In contrast, the discrimination of correct from incorrect answers may be more dependent on ability to attend to the features of each retrieved memory.

Journal article (peer-reviewed)abstract
- The aim of the study was to investigate the relation between the phenomenological quality of memory (Tulving, 1985) and the realism (validity) in confidence judgement when using emotional pictures (I.A.P.S; Lang, Ohman, & Vaitl, 1988). A series of three experiments was completed where the participants judged the phenomenological quality of their memory and/or their confidence. The results showed facilitation for the negative pictures in a matrix search task in the encoding phase, where negative pictures were more easily and quickly detected, compared to positive ones. In the memory phase of the experiments a higher degree of recollective experience (a larger proportion of 'remember' responses) was found for negative pictures. A higher level of confidence for recognition of negative pictures than for positive ones was obtained, but no general valence dependent effect on the realism in the confidence judgement was found. However, when analysing only the remember responses, negative pictures showed higher overconfidence than the positive pictures. The results support that a recollective experience induces higher confidence and overconfidence.
