Links between self-reported and laboratory behavioral impulsivity

Havik, M., Jakobson, A., Tamm, M., Paaver, M., Konstabel, K., Uusberg, A., Allik, J., Ööpik, V. & Kreegipuu, K. (2012). Links between self‐reported and laboratory behavioral impulsivity. Scandinavian Journal of Psychology 53, 216–223. A major problem in the research considering impulsivity is the lack of mutual understanding on how to measure and define impulsivity. Our study examined the relationship between self‐reported impulsivity, behavioral excitatory and inhibitory processes and time perception. Impulsivity – fast, premature, thoughtless or disinhibited behavior – was assessed in 58 normal, healthy participants (30 men, mean age 21.9 years). Self‐reported impulsivity as measured by Adaptive and Maladaptive Impulsivity Scale (AMIS) and behavioral excitatory and inhibitory processes as measured by Stop Signal Task were not directly related. Time perception, measured by the retrospective Time Estimation Task, was related to both. The length of the perceived time interval was positively correlated to AMIS Disinhibition subscale and negatively to several Stop Signal Task parameters. The longer subjects perceived the duration to last, the higher was their score on Disinhibition scale and the faster were their reactive responses in the Stop Signal Task. In summary our findings support the idea of cognitive tempo as a possible mechanism underlying impulsive behavior.     

Fat talk and self-presentation of body image: Is there a social norm for women to self-degrade?

The current investigations build upon previous ethnographic research, which identified a social norm for adolescent females to engage in “fat talk” (informal dialogue during which individuals express body dissatisfaction). In Study 1, participants were shown a vignette involving women engaging in fat talk dialogue and were subsequently asked to chose one of three self-presentational responses for a target female: (1) self-accepting of her body, (2) providing no information, or (3) self-degrading about her body. Male and female participants believed the target would be most likely to self-degrade, and that this would lead women to like her, while the self-accepting response would lead men to like her most. Study 2 used the same vignette but participants were asked to respond in an open-ended fashion. Participants again expected the target female to self-degrade. The present findings suggest college students perceive fat talk self-degradation of body image as normative.     

Paranormal and Religious Believers Are More Prone to Illusory Face Perception than Skeptics and Non‐believers

Illusory face perception, a tendency to find human‐like faces where none are actually present in, for example, artifacts or scenery, is a common phenomenon that occasionally enters the public eye. We used two tests (N = 47) to analyze the relationship between paranormal and religious beliefs and illusory face perception. In a detection task, the participants detected face‐like features from pictures of scenery and landscapes with and without face‐like areas and, in a rating task, evaluated the face‐likeness and emotionality of these areas. Believer groups were better at identifying the previously defined face‐like regions in the images but were also prone to false alarms. Signal detection analysis revealed that believers had more liberal answering criteria than skeptics, but the actual detection sensitivity did not differ. The paranormal believers also evaluated the artifact faces as more face‐like and emotional than the skeptics, and a similar trend was found between religious and non‐religious people.

Structure and Continuity of Well-Being in Mid-Adulthood: A Longitudinal Study

The present study analyzed whether the tripartite model of well-being (Keyes in J Health Soc Res 43:207–222, 2002; Journal of Consulting and Clinical Psychology 73:539–548, 2005a) and low depression can be captured by a core factor. Furthermore, it examined whether well-being shows continuity from early middle adulthood to middle adulthood. The study was based on the Finnish Jyväskylä Longitudinal Study of Personality and Social Development (Pulkkinen 2006), where the same participants (initial N = 369; 53% males) have been followed from age 8 until middle age. Data gathered at ages 36 and 42 were used. Well-being was indicated by (a) emotional well-being (including positive mood and low negative mood, satisfaction with different life-domains, and happiness); (b) Scales of Psychological Well-Being (Ryff in J Pers Soc Psychol 57:1069–1081, 1989); (c) Scales of Social Well-Being (Keyes in Soc Psychol Q 61:121–140, 1998); and (d) low level of depression. These measures were administered at both ages (except for social well-being, which was available only at age 42). The results, based on structural equation modeling, showed that a latent factor consisting of the above dimensions of well-being fit the data and that the structure of well-being was the same across genders and time. Well-being showed a high continuity from age 36 to 42 (standardized coefficient 0.84). As a conclusion, the different dimensions of well-being had only little variance of their own and a core factor of well-being was empirically established.     

Concordance of teacher-rated and performance-based measures of executive functioning in preschoolers

The most common method used to evaluate child behavior and functioning is rating scales completed by parents and/or teachers. Given that executive functioning (EF) plays a fundamental role in the developing child’s cognitive, behavioral, and social-emotional development, it would be ideal if ratings of EF and performance-based EF measures assess the same construct. However, most studies report a small to negligible association between performance-based measures and ratings of EF. There are few studies investigating this association for preschoolers, and most only include parent ratings. Teachers may be more reliable reporters of EF behaviors due to the higher demand for EF skills in the preschool setting than at home and because teachers may have a better sense of what behaviors are normative. In this study, we reviewed the associations between three EF rating scales completed by teachers on 243 preschool children. Results showed small to moderate correlations with EF measures of inhibition and cognitive flexibility/switching for all three scales, with the strongest associations observed between Child Behavior Rating Scale (CBRS) Behavioral Regulation subscale and child EF measures. Exploratory multivariate path analyses showed that, after controlling for age, sex, and socioeconomic status (SES), Behavioral Regulation significantly predicted performance-based measures of EF and accounted for incrementally more variance in the models. We conclude that in ideal situations, it is best to measure EF using both rating scales and performance-based measures of EF. The CBRS seems to be a sensitive measure of EF in preschoolers and may be a helpful brief screening tool for use with teachers.     

Biblical mothers as images of the Church

Among the many images and symbols of the Church which the church Fathers used, biblical mothers had an important role. Some of these images, such as Mary as an image of the Church, became widespread and have influenced later Christian theology and iconography. In this article, both the development and different applications of these images will be explored. How and to what purpose these images were used in the Early Church will also be studied. Among the topics dealt with by using these images were the origin, age, character and purpose of the Church, as well as its relation to several ‘others’ (the Jews, the schismatics and the heretics). In modern ecclesiological discussions, especially of Eve and Mary as images of the Church, the role of the Church in salvation, as well as the communal interpretation of biblical mothers, are relevant.     

Erlebnisbasierte und verfälschte Erinnerungen im EEG: Eine Pilotstudie

The present study aims to discriminate true and false memory by examining the EEG activity in a setting as applied as possible to the context of credibility assessment. To achieve this, 19 participants saw a short film about a robbery and had to answer 35 yes-no-questions, 25 of them contained misleading information. In order to distort the participants’ memories suggestive techniques were implemented, e. g. repeated questioning. The comparison of event-related potentials (ERP) of true and false memories reveals a parieto-occipital effect between 350 and 500 ms. This effect is consistent with the parietal old/new effect, which is associated with recollection. At the same time, this finding is in agreement with research associating a transient negativity (N400) with processing of semantic incongruent information.     

Development of the positive–negative asymmetry effect: in‐group exclusion norm as a mediator of children's evaluations on negative attributes

Two studies were conducted that go beyond previous research by examining when and why children might show intergroup bias in the attribution of positive, but not negative traits (PNAE: the positive–negative asymmetry effect, Mummendey & Otten, 1998, European review of social psychology, Vol. 9). In Study 1 (n = 107) children completed a ‘mixed’ trait attribution task in a dichotomous group context. As predicted there was a developmental trend between 7 and 12 years of age in the PNAE. The 7‐year olds were the only age group not to show the effect. Study 1 also found a quadratic developmental trend in children's national intergroup bias. Study 2 (n = 62) replicated the developmental path of the PNAE found in Study 1 using a wider age range of 6–16 years. This study used a ‘mixed’ list of traits which were not only antonyms and a procedure that made the positive and negative trait dimensions explicitly independent. Significantly, Study 2 found in‐group exclusion norm partially mediated the development of the PNAE. These findings support an account of the positive–negative asymmetry effect based upon normative processes. Copyright © 2006 John Wiley & Sons, Ltd.     

Emotional modulation of attention affects time perception: Evidence from event-related potentials

Emotional effects on human time perception are generally attributed to arousal speeding up or slowing down the internal clock. The aim of the present study is to investigate the less frequently considered role of attention as an alternative mediator of these effects with the help of event-related potentials (ERPs). Participants produced short intervals (0.9, 1.5, 2.7, and 3.3 s) while viewing high arousal images with pleasant and unpleasant contents in comparison to neutral images. Behavioral results revealed that durations were overproduced for the 0.9 s interval whereas, for 2.7 and 3.3 s intervals, underproduction was observed. The effect of affective valence was present for the shorter durations and decreased as the target intervals became longer. More specifically, the durations for unpleasant images were less overproduced in the 0.9 s intervals, and for the 1.5 s trials, durations for unpleasant images were slightly underproduced, compared to pleasant images, which were overproduced. The analysis of different ERP components suggests possible attention processes related to the timing of affective images in addition to changes in pacemaker speed. Early Posterior Negativity (EPN) was larger for positive than for negative images, indicating valence-specific differences in activation of early attention mechanisms. Within the early P1 and the Late Positive Potential (LPP) components, both pleasant and unpleasant stimuli exhibited equal affective modulation. Contingent Negative Variation (CNV) remained independent of both timing performance and affective modulation. This pattern suggests that both pleasant and unpleasant stimuli enhanced arousal and captured attention, but the latter effect was more pronounced for pleasant stimuli. The valence-specificity of affective attention revealed by ERPs combined with behavioral timing results suggests that attention processes indeed contribute to emotion-induced temporal distortions, especially for longer target intervals.
