- Taking a social psychological approach to metacognitive judgments, this study analyzed the difference in realism (validity) in confidence and frequency judgments (i.e., estimates of overall accuracy) between one’s own and another person’s answers to general knowledge questions. Experiment 1 showed that when judging their own answers, compared with another’s answers, the participants exhibited higher overconfidence, better ability to discriminate correct from incorrect answers, lower accuracy, and lower confidence. However, the overconfidence effect could be attributable to the lowest level of confidence. Furthermore, when heeding additional information about another’s answers the participants showed higher confidence and better discrimination ability. The overconfidence effect of Experiment 1 was not found in Experiment 2. However, the results of Experiment 2 were consistent with Experiment 1 in terms of discrimination ability, confidence, and accuracy. Finally, in both experiments the participants gave lower frequency judgments of their own overall accuracy compared with their frequency judgments of another person’s overall accuracy.

- This study investigated to what extent, and under what circumstances, pair collaboration influences the realism in eyewitness confidence in event memory. The participants first saw a short film clip and then confidence rated their answers to questions on its content. A condition (the Individual–Pair condition) where individual effort preceded pair collaboration showed better calibration compared with a condition (the Simple Pair condition) where no individual effort took place. Furthermore, within the Individual–Pair condition, better calibration, and lower overconfidence, were found in the pair phase compared with the individual phase. The eyewitnesses in the Individual–Pair condition made more realistic judgements of the total number of questions answered correctly. In a control experiment no effect on realism in confidence was found when individuals performed the same task twice. The improved realism in the Individual–Pair condition may partly be explained in terms of the increased accuracy and lowered confidence found for such items where the pair members’ had given different answers in the individual phase, and by a risky shift effect for such items where they had given the same answer.

Tidskriftsartikel (refereegranskat)abstract
- This three-year longitudinal study examined both within- and between-person effects of moral disengagement on verbal bullying perpetration in early adolescence. Data came from the first four waves (T1-T4, Grades 4 to 7) of an ongoing longitudinal project examining social and moral correlates of bullying in Swedish schools. Participants included 2432 Swedish early adolescents (52% girls; Mage at T1 = 10.55 years). Students completed self-report measures of verbal bullying perpetration and moral disengagement. Results of a multilevel growth model showed that verbal bullying increased over time (regression coefficient for Grade was b = 0.04, SE = 0.01, p < .001). Additionally, the verbal bullying trajectories of participants with higher average levels of MD were higher (regression coefficient for MD¯ was b = 0.28, SE = 0.02, p < .001) and steeper (regression coefficient for the Grade ×MD¯ interaction was b = 0.02, SE = 0.01, p = .018), indicating that these students scored higher on verbal bullying in general and increased more in verbal bullying over time, compared to students with lower levels of average MD. Variations around one's own mean of MD over time was also significantly associated with concurrent changes in verbal bullying (regression coefficient for time-varying MD was b = 0.21, SE = 0.01, p < .001).

- This study examined age differences in phasic heart rate in response to neutral, negative and positive pictures. Heart rate changes and subjective ratings were analyzed in 22 middle-aged (40-55 years) and 30 older (56-78 years) participants. The effects of valence on the HR pattern across time were similar to that obtained by Bradley and co-workers. Conversely to previous studies, we did not report any age-related reduction in cardiac reactivity. Instead, when viewing positive pictures, the triphasic wave form appeared in the group of older adults, but for younger participants, it was replaced by a sustained deceleration. These results were interpreted in the light of the socioemotional selectivity theory.

- Including vulnerable groups of students such as students with learning disabilities in mainstream school research, require ethical considerations and questionnaire adaptation. These students are often excluded, due to low understanding or methodologies generating inadequate data. Students with disability need be studied as a separate group and provided accessible questionnaires. This pilot study aims at developing and evaluating student self-reported measures, rating aspects of student experiences of school-based Physical Education (PE). Instrument design, reliability and validity were examined in Swedish secondary school students (n = 47) including students, aged 13, with intellectual disability (n = 5) and without impairment and test–retested on 28 of these students. Psychometric results from the small pilot-study sample were confirmed in analyses based on replies from the first wave of data collection in the main study (n = 450). Results show adequate internal consistency, factor structure and relations between measures. In conclusion, reliability and validity were satisfactory in scales to measure self-efficacy in general, in PE, and aptitude to participate. Adapting proxy ratings for functioning into self-reports indicated problems. Adequacy of adjustments made were confirmed and a dichotomous scale for typical/atypical function is suggested for further analyses.

- School bullying is a complex social and relational phenomenon with severe consequences for those involved. Most children view bullying as wrong and recognize its harmful consequences; nevertheless, it continues to be a persistent problem within schools. Previous research has shown that children's engagement in bullying perpetration can be influenced by multiple factors (e.g., different forms of cognitive distortions) and at different ecological levels (e.g., child, peer-group, school, and society). However, the complexity of school bullying warrants further investigation of the interplay between factors, at different levels. Grounded in social cognitive theory, which focuses on both cognitive factors and social processes, this study examined whether children's bullying perpetration was associated with moral disengagement at the child level and with collective moral disengagement and prevalence of pro-bullying behavior at the classroom level. Cross-level interactions were also tested to examine the effects of classroom-level variables on the association between children's tendency to morally disengage and bullying perpetration. The study's analyses were based on cross-sectional self-report questionnaire data from 1,577 Swedish fifth-grade children from 105 classrooms (53.5% girls; Mage = 11.3, SD = 0.3). Multilevel modeling techniques were used to analyze the data. The results showed that bullying perpetration was positively associated with moral disengagement at the child level and with collective moral disengagement and pro-bullying behavior at the classroom level. Furthermore, the effect of individual moral disengagement on bullying was stronger for children in classrooms with higher levels of pro-bullying behaviors. These findings further support the argument that both moral processes and behaviors within classrooms, such as collective moral disengagement and pro-bullying behavior, need to be addressed in schools' preventive work against bullying.

- This study examined the links between seven specific mechanisms of moral disengagement and indirect bullying, direct bullying, and pro-aggressive bystander behavior. In addition, the moderating role of gender on these associations was examined. Participants were 317 Swedish students in Grades 4 to 8 (Mage=12.6, SD = 1.35; 62% girls). Multivariate multiple regression analyses showed that indirect bullying was predicted by gender and victim attribution. Direct bullying was predicted by moral justification, and for girls, by victim attribution. Pro-aggressive bystander behavior was predicted by diffusion of responsibility, victim attribution, gender, and age. That is, boys and younger students were more prone to take the aggressor’s side compared with girls and older students. Furthermore, the relation between pro-aggressive bystander behavior and distortion of consequences appeared stronger in boys than in girls. These results highlight the relative importance of specific moral disengagement mechanisms and may have implications for interventions targeting bullying.

Episodiskt minne : finns det något sådant?

- The distinction between semantic and episodic memory is discussed on the basis of an empirical study focusing on mental representations and autobiographical memory. The notion of episodic memory is called in question. An alternative model is proposed which is grounded in whether the memory is refering to the self or not, and if a phenomenal reliving experience is activated or not. In the proposed model autobiographical memory and semantic memory are partly overlapping but the recollective memory is regarded to be a "natural kind" and consequently secluded. Everything a person knows and remembers has its origin in experiences. If the experiences are emotionally significant for the self they will fill a different function for the individual than they will if they are emotionally neutral. This is the crucial point for whether the memory of an experience will become a semantic memory or an autobiographical memory.

- 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.

- Groove-based rhythm is a basic and much appreciated feature of Western popular music. It is commonly associated with dance, movement and pleasure and is characterized by the repetition of a basic rhythmic pattern. At various points in the musical course, drum breaks occur, representing a change compared to the repeated pattern of the groove. In the present experiment, we investigated the brain response to such drum breaks in a repetitive groove. Participants were scanned with functional magnetic resonance imaging (fMRI) while listening to a previously unheard naturalistic groove with drum breaks at uneven intervals. The rhythmic pattern and the timing of its different parts as performed were the only aspects that changed from the repetitive sections to the breaks. Differences in blood oxygen level-dependent activation were analyzed. In contrast to the repetitive parts, the drum breaks activated the left cerebellum, the right inferior frontal gyrus (RIFG), and the superior temporal gyri (STG) bilaterally. A tapping test using the same stimulus showed an increase in the standard deviation of inter-tap-intervals in the breaks versus the repetitive parts, indicating extra challenges for auditory-motor integration in the drum breaks. Both the RIFG and STG have been associated with structural irregularity and increase in musical-syntactical complexity in several earlier studies, whereas the left cerebellum is known to play a part in timing. Together these areas may be recruited in the breaks due to a prediction error process whereby the internal model is being updated. This concurs with previous research suggesting a network for predictive feed-forward control that comprises the cerebellum and the cortical areas that were activated in the breaks.
