A review of the H-reflex and M-wave in the human triceps surae

The soleus is the most commonly used muscle for H-reflex studies in humans, while limited comparable data have been produced from the gastrocnemii muscles. This article reviews the fundamental differences between the structure and function of the human soleus and gastrocnemii muscles, including recent data published about their complex innervation zones. Protocols for eliciting, recording, and assessing the H-reflex and M-wave magnitude in the human triceps surae are also discussed.     

It's different to give than to receive: predictors of givers' and receivers' reactions to favor exchange

The present research examines episodes of favor exchange among peer employees. We posit that favor receivers' and favor givers' commitment to their exchange relationships with one another will be accounted for by different factors. As predicted, in 2 different organizational contexts, receivers' commitment to their relationships with givers was found to be more related to their judgments of the givers' interactional justice when performing the favor, whereas givers' commitment to their relationships with receivers was shown to be more associated with their judgments of the favorability of the outcomes associated with the favor that they performed. The implications of these findings for how givers and receivers can better manage favor exchange, and hence their relationships with each other, are discussed.     

Empathic and non-empathic routes to visuospatial perspective-taking

The present study examined whether strategy moderated the relationship between visuospatial perspective-taking and empathy. Participants (N=96) undertook both a perspective-taking task requiring speeded spatial judgements made from the perspective of an observed figure and the Empathy Quotient questionnaire, a measure of trait empathy. Perspective-taking performance was found to be related to empathy in that more empathic individuals showed facilitated performance particularly for figures sharing their own spatial orientation. This relationship was restricted to participants that reported perspective-taking by mentally transforming their spatial orientation to align with that of the figure; it was absent in those adopting an alternative strategy of transposing left and right whenever confronted with a front-view figure. Our finding that strategy moderates the relationship between empathy and visuospatial perspective-taking enables a reconciliation of the apparently inconclusive findings of previous studies and provides evidence for functionally dissociable empathic and non-empathic routes to visuospatial perspective-taking.     

Modifying CBT for Perinatal Depression: What Do Women Want?: A Qualitative Study

The evidence for the efficacy of CBT for depression during the perinatal period is mixed. This was a qualitative study that aimed to understand the perinatal-specific needs of depressed women in an effort to inform treatment modifications that may increase the relevance and acceptability of CBT during this period. Stratified purposeful sampling resulted in 23 participants selected by pregnancy, socioeconomic, and depression status. Participants completed semistructured interviews exploring their experiences of pregnancy and the postpartum period and its relationship to mood, and perspectives on ideal treatment content. Thematic analysis revealed a number of perinatal-specific themes that were relevant to CBT in three key domains: self, motherhood, and interpersonal. Mothers particularly struggled with: internalization of “motherhood myths,” self-sacrifice, and managing social support during this period. Shifts in women's themes across the perinatal period, and between racial and socioeconomic groups are discussed as are implications for modification of CBT to improve relevance for perinatal depression.     

The Cultural Community: An Husserlian Approach and Reproach

What types of unity and disunity belong to a group of people sharing a culture? Husserl illuminates these communities by helping us trace their origin to two types of interpersonal act—cooperation and influence—though cultural communities are distinguished from both cooperative groups and mere communities of related influences. This analysis has consequences for contemporary concerns about multi- or mono-culturalism and the relationship between culture and politics. It also leads us to critique Husserl’s desire for a new humanity, one that is rational, cooperatively united, and animated by a universal philosophical culture. Reflecting on culture, a spiritually shaped and shared domain of the world, draws us to reflect also on ourselves as social and rational animals, and to ask, what should we reasonably hope for—and aim for—in a human culture that expresses and supports our shared lives of reason? Aristotle is used for occasional comparisons and contrasts.     

Internalizing Symptoms in Female Adolescents: Associations with Emotional Awareness and Emotion Regulation

The transition into adolescence involves a number of changes that for many adolescents result in increased negative affect and internalizing symptoms, especially for females. In the current study we examined the direct and indirect effects of emotional awareness on internalizing symptoms by exploring the extent to which certain emotion regulation strategies influence this relationship. Participants were 123 female adolescents aged 13–16 years (M = 14.51 years) who completed measures of emotional awareness, emotion regulation (emotional reappraisal and expressive suppression), and symptoms of depression and social anxiety. Two multiple indirect effect models were conducted including both reappraisal and suppression (one for each of the dependent variables, depression and social anxiety) via the bootstrapping method. Results found that reappraisal accounted for the effect of emotional awareness on depressive symptoms but suppression accounted for the effect of emotional awareness on social anxiety symptoms. Results suggest that emotion regulation strategies play an important role in determining depressive and social anxiety symptoms and are associated with an adolescent’s level of emotional awareness.     

The “Hidden” Technology of Effective Parent Consultation: A Guided Participation Model for Promoting Change in Families

Parenting interventions based on social learning principles are amongst the most effective interventions available to prevent and manage social, emotional and behavioral problems in children and adolescents. The most successful programs employ active skills training methods (modeling, rehearsal, practice, feedback and homework) to teach new parenting skills. However, effective parent consultation also involves a broader range of interpersonal and process skills such as building a collaborative relationship, facilitating parent receptivity to new ideas or skills, managing within session resistance, and important micro skills associated with clinical tasks such as promoting parents self-regulation, independent problem solving and autonomy. This paper aims to articulate the “hidden” technology of effective parent consultation and identify implications for research on mechanisms of change in parenting interventions and practitioner training.

Personality predicts innovation and social learning in children: Implications for cultural evolution

Innovation and social learning are the pillars of cultural evolution, allowing cultural behaviours to cumulatively advance over generations. Yet, little is known about individual differences in the use of social and asocial information. We examined whether personality influenced 7-11-year-old children's (N = 282) propensity to elect to observe others first or independently generate solutions to novel problems. Conscientiousness was associated with electing for no demonstrations, while agreeableness was associated with opting for demonstrations. For children receiving demonstrations, openness to experience consistently predicted deviation from observed methods. Children who opted for no demonstrations were also more likely than those opting for demonstrations to exhibit tool manufacture on an innovation challenge and displayed higher creativity, as measured by an alternate uses task. These results highlight how new cultural traditions emerge, establish and advance by identifying which individuals generate new cultural variants in populations and which are influential in the diffusion of these variants, and help reduce the apparent tension within the ‘ratchet’ of cumulative culture.
