Reported serial positions of true and illusory memories in the Deese/Roediger/McDermott paradigm

One of the easiest ways to induce illusory memories in the laboratory is to use the Deese–Roediger–McDermott (DRM) word-list paradigm. Researchers have used this paradigm not only to study people's memories of stimuli that were not actually presented, but also to study the phenomenological qualities of these illusions. In four experiments, the current investigation explored a phenomenological quality of illusory memories that has received almost no attention, specifically, temporality. A serial position task was incorporated into the DRM paradigm to examine temporal attributes of participants' true and false memories. Effects of list strength, presentation order, and types of warnings were examined. Results showed consistent serial position responses for true and false memories. However, only responses for illusory memories were affected by manipulations at study. The current findings thus lend support to encoding-based explanations of false recollections.     

Executive Functioning and Non-Verbal Intelligence as Predictors of Bullying in Early Elementary School

Executive function and intelligence are negatively associated with aggression, yet the role of executive function has rarely been examined in the context of school bullying. We studied whether different domains of executive function and non-verbal intelligence are associated with bullying involvement in early elementary school. The association was examined in a population-based sample of 1,377 children. At age 4 years we assessed problems in inhibition, shifting, emotional control, working memory and planning/organization, using a validated parental questionnaire (the BRIEF-P). Additionally, we determined child non-verbal IQ at age 6 years. Bullying involvement as a bully, victim or a bully-victim in grades 1–2 of elementary school (mean age 7.7 years) was measured using a peer-nomination procedure. Individual bullying scores were based on the ratings by multiple peers (on average 20 classmates). Analyses were adjusted for various child and maternal socio-demographic and psychosocial covariates. Child score for inhibition problems was associated with the risk of being a bully (OR per SD?=?1.35, 95%CI: 1.09–1.66), victim (OR per SD?=?1.21, 95%CI: 1.00–1.45) and a bully-victim (OR per SD?=?1.55, 95%CI: 1.10–2.17). Children with higher non-verbal IQ were less likely to be victims (OR?=?0.99, 95%CI: 0.98–1.00) and bully-victims (OR?=?95%CI: 0.93–0.98, respectively). In conclusion, our study showed that peer interactions may be to some extent influenced by children’s executive function and non-verbal intelligence. Future studies should examine whether training executive function skills can reduce bullying involvement and improve the quality of peer relationships.     

Flow experience and team performance: The role of team goal commitment and information exchange

While a number of studies show that the flow experience is related to different outcomes at the individual level, the role of flow in work teams remains unclear. This study contributes to the advancement of knowledge on flow by testing the relationships between this psychological state, team goal commitment and team performance. Data were gathered from 85 teams comprised of graduate and undergraduate students who participated in a project management simulation. The results show that the flow experience is positively related to team performance. This relationship is mediated by team goal commitment and moderated by the level of information exchange between team members. In practical terms, the results of this study show that managers should implement interventions fostering the flow experience in their teams, while at the same time encouraging information exchange between members.     

The Delay Before Recall Changes the Remembered Duration of 15‐minute Video Sequences

The aim of this study was to determine if the passage of time changes the memory of the duration of joyful or sad events. Participants were asked to look at a series of brief videos lasting 15 minutes and to estimate retrospectively and verbally (with chronometric units) the duration of this 15‐minute period. There were two independent variables: the emotion conditions (joy, sadness and neutral) and the recall conditions (immediately after the presentation of videos, 1 week later or 1 month later). The results show that the estimated time is largely overestimated in the 1‐week and 1‐month condition but not when the recall is immediate. This effect applies to each emotional condition, but there was no significant difference between the emotion conditions. The effect of emotion on the estimation of long intervals judged retrospectively seems minimal in comparison with the cognitive effect associated with the passage of time.

Discrimination of two neighboring intra- and intermodal empty time intervals marked by three successive stimuli

We investigated the discrimination of two neighboring intra- or inter-modal empty time intervals marked by three successive stimuli. Each of the three markers was a flash (visual—V) or a sound (auditory—A). The first and last markers were of the same modality, while the second one was either A or V, resulting in four conditions: VVV, VAV, AVA and AAA. Participants judged whether the second interval, whose duration was systematically varied, was shorter or longer than the 500-ms first interval. Compared with VVV and AAA, discrimination was impaired with VAV, but not so much with AVA (in Experiment 1). Whereas VAV and AVA consisted of the same set of single intermodal intervals (VA and AV), discrimination was impaired in the VAV compared to the AVA condition. This difference between VAV and AVA could not be attributed to the participants' strategy to perform the discrimination task, e.g., ignoring the standard interval or replacing the visual stimuli with sounds in their mind (in Experiment 2). These results are discussed in terms of sequential grouping according to sensory similarity.     

The development and validation of a measure of character: The CIVIC

The present research study sought to develop and validate a character scale – the Comprehensive Inventory of Virtuous Instantiations of Character using a total sample size of 3679 across five studies. In Study 1, character trait items were generated using an integrative classification system. In Study 2, character trait scales were further refined and their factor structure examined, revealing eight higher-order character dimensions or character cores: appreciation, intellectual engagement, fortitude, interpersonal consideration, sincerity, temperance, transcendence, and empathy. Study 3 established convergent validity of character traits with extant measures and discriminability from personality facets, social desirability, and moral cognitive development. Study 4 revealed that character cores were more strongly related to evaluative constructs than personality dimensions. Study 5 demonstrated that character cores predicted performance and psychological well-being outcomes above and beyond personality. The implications of our findings for the assessment and taxonomy of character are discussed.     

Associations between Stress,Psychosomatic Complaints,and Parental Criticism among Affluent Adolescent Girls

A growing body of research has shown that adolescent girls in the context of affluence face a series of unique pressures that may increase social-emotional problems. Little research, however, has examined associations between perceived stress and psychosomatic complaints among privileged youth. In the present study, we investigated the relationships between stress, psychosomatic complaints, and parental criticism in a sample of preadolescent and adolescent girls (n?=?218) from selective, private schools. Using OLS regression analyses, cross-sectional and longitudinal associations were evident between perceived stress and psychosomatic complaints, with increases in stress associated with increases in psychosomatic problems. Parental criticism was also examined as a predictor of girls’ psychosomatic complaints and stress levels. Results indicated that parental criticism was significantly and positively associated with psychosomatic problems in cross-sectional models and that perceived stress levels mediated this association. Additional analyses demonstrated that the relationship between psychosomatic complaints and stress may be bidirectional. Taken together, results from this exploratory study suggest that girls in the context of affluence may also experience psychosomatic complaints, in addition to social-emotional problems.
