Infants’ grip strength predicts mu rhythm attenuation during observation of lifting actions with weighted blocks

Research has established that the body is fundamentally involved in perception: bodily experience influences activation of the shared neural system underlying action perception and production during action observation, and bodily characteristics influence perception of the spatial environment. However, whether bodily characteristics influence action perception and its underlying neural system is unknown, particularly in early ontogeny. We measured grip strength in 12‐month‐old infants and investigated relations with mu rhythm attenuation, an electroencephalographic correlate of the neural system underlying action perception, during observation of lifting actions performed with differently weighted blocks. We found that infants with higher grip strength exhibited significant mu attenuation during observation of lifting actions, whereas infants with lower grip strength did not. Moreover, a progressively strong relation between grip strength and mu attenuation during observation of lifts was found with increased block weight. We propose that this relation is attributable to differences in infants’ ability to recognize the effort associated with lifting objects of different weights, as a consequence of their developing strength. Together, our results extend the body's role in perception by demonstrating that bodily characteristics influence action perception by shaping the activation of its underlying neural system.     

Children’s and Adolescents’ Conceptions of Happiness

Previous research on children’s and adolescents’ happiness has mainly focused on the different variables that may contribute to it. However, very few studies have investigated the beliefs that children and adolescents hold about happiness. It is important to study developmental and gender differences in the conceptions of happiness as beliefs affect people’s emotions and behaviors, and they may help explain how children and adolescents strive for their own (and potentially others’) happiness. To that aim, we conducted two different studies. In Study 1a 20 people (lay judges) completed two categorization tasks to obtain categorization systems that may include all the relevant content categories identified in previous literature with adults, adolescents and children. In Study 1b, we asked 162 children and adolescents to define—in their own words—what happiness meant for them. Their responses were coded according to two different systems derived from previous finding with adults and children and to an alternative coding system derived from the qualitative analyses of children’s and adolescents’ responses. Overall, results showed that hedonic conceptualization of happiness were mainly present in late childhood; whereas eudaimonic conceptualizations were mainly present in adolescence. No significant gender differences were found.     

ePortfolio as a tool for reflection and self-reflection

The request and promotion of reflection begins with an analysis of one’s own understanding of education and learning as well as the connection of reflection and self-reflection and the competence development of students. A self-reflective attitude should be promoted early on by encouraging students to understand (reflection), to evaluate (evaluation), and, if necessary, to adapt (regulation) their own learning behavior. To encourage reflection, self-reflection, and competence development, the use of an ePortfolio can provide a valuable contribution. However, the implementation process of an ePortfolio for pre-service teachers remains a debated method. This research paper investigates the impact and sustainability of an ePortfolio-implementation regarding students’ competence development and reflection skills in a Master’s Program for Business Education and Development (BED). The survey was conducted between October 2011 and June 2014 (n = 811) and consists of six sequential questionnaires. The students assessed the positive impact on their (self-)reflection. When being asked about their most distinctive competences, students’ responses emphasize their previous ePortfolio-sessions, thus indicating a positive impact of the ePortfolio on students’ self-perceived competences.     

“We All Have Feelings for Our Girlfriends:” Progressive (?) Representations of Lesbian Lives on the <Emphasis Type="Italic">The L Word</Emphasis>

The Showtime series The L Word (2004–2009) marked one of the first dramatized representations of prominent lesbian characters. While many popular culture scholars are focusing attention on the recent “gaying” of television narrative (e.g., Battles and Hilton-Morrow in Critical Studies in Media Communication 19: 87–105, 2002; Shugart in Text and Performance Quarterly 23: 30–54, 2003; Critical Studies in Media Communication 20: 67–91, 2003), far less attention is given to non-romantic interpersonal relationships surrounding main characters in these narratives. Sexuality scholarship notes that lesbian individuals must negotiate their self-disclosure to heterosexuals (Dindia in Dialectical approaches to studying personal relationships, Lawrence Erlbaum Associates Inc., Mahwah, NJ, 1998), and that this can be challenging for forming relationships and maintaining identity (Meyer in Communication Quarterly 51: 262–276, 2004). Ultimately, this essay argues that despite the gains in visibility and even in intimacy, The L Word articulates an ideology of avoidance whereby the underlying problems of heterosexism and homophobia are left unchallenged.     

Worry and anxiety account for unique variance in the relationship between intolerance of uncertainty and depression

The evidence supporting the relationship between intolerance of uncertainty (IU), a cognitive construct well established in the anxiety literature, and depression is mixed. Some research has demonstrated a direct association between IU and depression, whereas other studies suggest that IU is either unrelated or indirectly related to depression through other pathways, including anxiety. The present study aimed to further elucidate the relationship between IU and depression in an undergraduate sample (N = 221). We posited a model in which worry and anxiety account for unique variance in the association between IU and depression. Results supported this hypothesis. Worry and trait anxiety significantly accounted for unique variance in the relationship between IU and depression. Furthermore, the model that best fit the data included two additional direct paths, from IU to anxiety and from worry to depression, and excluded the direct path from IU to depression. Our findings support the notion that IU and depression are indirectly related through worry and anxiety. Limitations and future directions are discussed.     

Effects of a companion dog on associations of danger and threat with oriental-looking targets

In the current study we extend previous findings on the shooter bias toward targets with Arab ethnicity. In an adapted shooter task, we presented stereotypically oriental-looking targets without explicit symbols of Islam (e.g., a turban) and additionally tested if presenting a “harmless” companion dog, together with Arab versus White targets, would affect the shooter bias. Participants responded faster and made fewer errors for armed Arab than for armed White targets. Moreover, compared to the “neutral” no dog condition, the presence of a dog triggered fewer false alarms for White than for Arab targets and slowed down (correct) responses in general. Implications and potential underlying mechanisms are discussed.     

The Providence of Language in Gadamer's Truth and Method

God, the true paranoid, for whom all is organised in spheres joyful or threatening about the central pulse of himself, the dreamer whose puns probe ancient foetid shafts and tunnels of truth all act in the same special relevance to the word, or whatever it is the word is there, buffering to protect us from. The act of metaphor then was a thrust at truth and a lie, depending where you were: inside, safe, or outside, lost.¹     

Integrity Tests and the Five‐Factor Model of Personality: A Review and Empirical Test of Two Alternative Positions

The psychological meaning of integrity test scores has been explored predominantly in relation to the five‐factor model of personality (FFM). Two alternative positions on this topic can be identified in the literature which state, respectively, that integrity tests measure (a) a higher‐order factor of personality covering three FFM dimensions or (b) a linear composite of numerous facets from various domains within the FFM. An empirical test of these alternative positions, using structural equation modeling, revealed that the value of both views depended on the type of integrity test examined. With a personality‐based integrity test, position (a) had to be refuted, whereas position (b) was strongly supported. There was also more supportive evidence for position (b) with an overt test, but the difference was far less pronounced than for the personality‐based measure. Possible consequences for theories on the role of personality in personnel selection are discussed.
