Dreaming in the multilevel framework

Biological realism ( [Revonsuo, 2001] and [Revonsuo, 2006] ) states that dreaming is a biological phenomenon and therefore explainable in naturalistic terms, similar to the explanation of other biological phenomena. In the biological sciences, the structure of explanations can be described with the help of a framework called ‘multilevel explanation’. The multilevel model provides a context that assists to clarify what needs to be explained and how, and how to place different theories into the same model. Here, I will argue that the multilevel framework would be useful when we try to construct scientific explanations of dreaming.     

Understanding others,reciprocity, and self-consciousness

The article explores the basic conceptual relationship between social cognition, intersubjectivity and self-consciousness. A much-debated recent approach to social cognition, the so-called interaction theory, is the view that the ability to perceive, understand and interpret the behavior of others relies on interaction in the sense of mutual coordination of the embodied agents involved. It will be shown that this notion of reciprocity is too weak in order to fully account for social understanding. It will be argued that the idea of reciprocity should at least in some cases be conceived of as a stance persons adopt towards each other, which in turn presupposes that they acknowledge each other as self-conscious agents. This view is inspired by an argument originally introduced by Johann Gottlieb Fichte.     

Long-term stability in the Big Five personality traits in adulthood

This study investigated the stability of the Big Five personality traits in adulthood from age 33 to 42. Participants (89 men, 103 women) were drawn from the ongoing Jyväskylä Longitudinal Study of Personality and Social Development. The results showed that the mean‐level of Neuroticism decreased whereas the mean‐level of Extraversion, Openness to Experience, Agreeableness, and Conscientiousness increased from age 33 to 42. The Structural Equation Modeling analyses revealed both gender differences and similarities in the rank‐order stability of the Big Five: Neuroticism and Extraversion were more stable in men than in women, whereas Openness to Experience, Agreeableness, and Conscientiousness were as stable in men as in women. Stability coefficients for the Big Five personality traits across 9 years were moderate to high, ranging from 0.73 to 0.97 in men and from 0.65 to 0.95 in women. The highest gender‐equal stability was found for Openness to Experience and the lowest for Conscientiousness.     

Sequence learning in Parkinson's disease: the effect of spatial stimulus-response compatibility

Patients with Parkinson's disease (PD) have repeatedly demonstrated reduced sequence-specific learning effects in serial reaction time tasks (SRTs). Previous research with PD patients has mainly employed the 'classical' SRT task, involving a spatially compatible assignment of stimuli and responses. From cognitive research, it is known that spatial compatibility triggers rapid, automatic responses in the direction of the stimulus. Automatic responding has shown to be disinhibited in PD patients and may therefore interfere with stimulus anticipation during the learning process. The aim of the present study was to test this hypothesis by investigating if reduced sequence-specific learning depends on spatial stimulus-response compatibility. PD patients and age-matched controls were examined either with an SRT variant involving central stimulus presentation, thereby preventing automatic linking of stimulus and response locations, or with a spatially compatible SRT task. Patients showed reduced sequence-specific learning effects only when the stimulus-response assignment was spatially compatible. This pattern of results confirms the hypothesis that sequence learning deficits in PD may result from a predominance of automatic response activation over learning-based stimulus anticipations during the learning phase.     

Character Strengths and Life Satisfaction in Later Life: an Analysis of Different Living Conditions

The aim of this study was to explore the role of character strengths and their associations to life satisfaction in older people. We were interested in studying several transitions that are specific for older people: aging, retirement, living alone, and being widowed. We examined the relationships of these demographic characteristics and living conditions with character strengths and studied their effects on the association of character strengths with life satisfaction. In a cross-sectional analysis, 15,598 older adults (aged 46–93 years) who had completed measures on character strengths, life satisfaction, and demographic characteristics and living conditions were selected from an existing database. Overall, analyses revealed positive associations of most character strengths with age, and higher scores in most character strengths for the employed (vs. the retired) and those living with a partner (vs. those living alone), while only few relationships with being widowed (vs. being married) were observed. Further, the contribution of character strengths to life satisfaction generally decreased slightly with age, but increased for certain character strengths, such as modesty or prudence. Also, stronger relationships between several character strengths and life satisfaction were found for retired people and those living alone, while being widowed did not affect these relationships. The results demonstrate how character strengths might contribute to the life satisfaction of older adults in various living conditions and thereby offer a starting point for strengths-based programs in later life.

     

Identifying reading strategies using latent semantic analysis: comparing semantic benchmarks.

We explored methods of using latent semantic analysis (LSA) to identify reading strategies in students' self-explanations that are collected as part of a Web-based reading trainer. In this study, college students self-explained scientific texts, one sentence at a time. ISA was used to measure the similarity between the self-explanations and semantic benchmarks (groups of words and sentences that together represent reading strategies). Three types of semantic benchmarks were compared: content words, exemplars, and strategies. Discriminant analyses were used to classify global and specific reading strategies using the LSA cosines. All benchmarks contributed to the classification of general reading strategies, but the exemplars did the best in distinguishing subtle semantic differences between reading strategies. Pragmatic and theoretical concerns of using LSA are discussed.     

Cross-lagged relations between kindergarten teachers’ causal attributions, and children’s interest value and performance in mathematics

The present study investigated mathematics performance and related interest value as the antecedents and consequences of teachers?? causal attributions concerning children??s academic outcomes during their kindergarten year. Sixty-nine children (5?C6?years old at the baseline) and their teachers were examined twice during the kindergarten year. Children were tested in mathematics performance and interviewed about their interest value. Teachers rated their causal attributions in the fall and spring. The results showed that the higher the interest value in mathematics children showed, the more the teacher attributed their success to ability and effort. Teachers?? ability attributions for success, in turn, contributed to an increase in children??s interest value in mathematics. Moreover, attributing children??s success and failure to external causes decreased children??s mathematics-related interest value.     

Processes underlying congruent and incongruent facial reactions to emotional facial expressions

The present electromyographic study is a first step toward shedding light on the involvement of affective processes in congruent and incongruent facial reactions to facial expressions. Further, empathy was investigated as a potential mediator underlying the modulation of facial reactions to emotional faces in a competitive, a cooperative, and a neutral setting. Results revealed less congruent reactions to happy expressions and even incongruent reactions to sad and angry expressions in the competition condition, whereas virtually no differences between the neutral and the cooperation condition occurred. Effects on congruent reactions were found to be mediated by cognitive empathy, indicating that the state of empathy plays an important role in the situational modulation of congruent reactions. Further, incongruent reactions to sad and angry faces in a competition setting were mediated by the emotional reaction of joy, supporting the assumption that incongruent facial reactions are mainly based on affective processes. Additionally, strategic processes (specifically, the goal to create and maintain a smooth, harmonious interaction) were found to influence facial reactions while being in a cooperative mindset. Now, further studies are needed to test for the generalizability of these effects.     

Fast similarities: efficiency advantages of similarity-focused comparisons

People constantly have to make efficient use of their limited cognitive resources. Recently, T. Mussweiler and K. Epstude (2009) demonstrated that comparative thinking simplifies information processing and increases the efficiency of judgment. However, there are different types of comparative thinking. While comparing 2 entities, people may focus on either similarities or dissimilarities between target and standard. The authors propose that these 2 comparative thinking styles differ in their efficiency. Specifically, the authors hypothesize that comparisons with a focus on similarities lead to more focused information processing and faster judgments than comparisons with a dissimilarity focus. In line with these hypotheses, the authors demonstrate that participants are indeed faster at judging the similarity of 2 stimuli (Study 1) and that they search for less target information in a comparative judgment task (Study 2) if they focus on similarities rather than dissimilarities. Focusing on similarities thus appears to be the more efficient comparative thinking style.
