First symbols in a girl with Down syndrome: A longitudinal study from 12 to 18 months

Symbolic uses of objects originate in communicative and triadic contexts (adult–child-object). In this longitudinal study we explore the emergence and development of the first symbolic uses in triadic interaction contexts in a girl with Down syndrome between 12 and 18-months of age. We conducted five sessions of video recording, at 12, 13½, 15, 16½, and 18 months chronological age. At each session we videotaped the girl and her mother interacting with different objects. Data were coded in semiotic categories used in previous studies (Rodríguez & Moro, 1999) and a microgenetic analysis was conducted for each session. The first symbolic uses by the girl appeared at 13½ months. Symbols were of different types and levels of complexity, and the adult had an important role in facilitating the production of these symbols.     

Instrumental and vocal music effects on EEG and EKG in neonates of depressed and non-depressed mothers

Neonates (M age = 16 days) born to depressed and non-depressed mothers were randomly assigned to hear an audiotaped lullaby of instrumental music with vocals or without vocals. Neonatal EEG and EKG were recorded for 2 min (baseline) of silence and for 2 min of one or the other music presentation. Neonates of non-depressed mothers showed greater relative right frontal EEG asymmetry to both types of music, suggesting a withdrawal response. Neonates of depressed mothers on the other hand showed greater relative left frontal EEG asymmetry to the instrumental without vocal segment, suggesting an approach response, and greater relative right frontal EEG asymmetry to the instrumental with vocal segment, suggesting a withdrawal response. Heart rate decelerations occurred following the music onset for both groups of infants, however, compared to infants of non-depressed mothers, infants of depressed mothers showed a delayed heart rate deceleration, suggesting slower processing and/or delayed attention. These findings suggest that neonates of depressed and non-depressed mothers show different EKG and EEG responses to instrumental music with versus without vocals.     

Moderate versus light pressure massage therapy leads to greater weight gain in preterm infants

Sixty-eight preterm infants (M GA = 30 weeks) were randomly assigned to a moderate or to a light pressure massage therapy group to receive 15 massages three times per day for 5 days. Behavior state, stress behaviors and heart rate were recorded for 15 min before and during the first 15-min therapy session. Weight gain was recorded over the 5-day therapy period. The moderate versus light pressure massage group gained significantly more weight per day. During the behavior observations the moderate versus light pressure massage group showed significantly lower increases from the pre-session to the session recording on: (1) active sleep; (2) fussing; (3) crying; (4) movement; and (5) stress behavior (hiccupping). They also showed a smaller decrease in deep sleep, a greater decrease in heart rate and a greater increase in vagal tone. Thus, the moderate pressure massage therapy group appeared to be more relaxed and less aroused than the light pressure massage group which may have contributed to the greater weight gain of the moderate pressure massage therapy group.     

Kierkegaard’s Regulative Sacrifice: A Post-Kantian Reading of Fear and Trembling

Abstract

The present paper suggests to consider Kierkegaard’s use of Abraham’s story in Fear and Trembling in regulative terms, that is, to consider it as a model – not for our moral behaviour but rather for our religious behaviour. To do so, I first rely on recent literature to argue that Kierkegaard should be regarded as a distinctively post-Kantian philosopher: namely, a philosopher who goes beyond Kant in a way that is nevertheless true to the spirit of Kant’s original critical philosophy. Then, I present a post-Kantian reading of Fear and Trembling, focusing on the problematic implications that result from comparing this text with Hegel’s theory of recognition. Finally, I submit that sacrifice in Fear and Trembling is a regulative notion in a Kantian sense. This interpretation addresses some of the most problematic aspects of the text. I conclude that the regulativity of sacrifice may be regarded as an important and perhaps an essential component of Kierkegaard’s overall philosophical strategy.     

Kant’s sacrificial turns

This paper addresses the role of the notion of sacrifice in Kant’s theoretical philosophy, practical philosophy, and in his account of religion. First, I argue that kenotic sacrifice, or sacrifice as ‘withdrawal’, plays a hidden and yet important role in the development of Kant’s transcendental philosophy. Second, I focus on Kant’s practical philosophy, arguing that the notion of sacrifice that is both implied and explicitly analyzed by Kant is mainly suppressive sacrifice. However, Kant’s account is fundamentally ambiguous, as sometimes the kenotic meaning of sacrifice seems to resurface, especially in the context of Kant’s discussion of the happiness of others as an end in itself. Because religious notions are regarded by Kant as necessary transitional forms (Darstellungen) to be used to make moral ideas applicable to the world, I then scrutinize Kant’s view of sacrifice as an improper symbol, and I analyze Kant’s arguments for such a dismissal and discuss the subject matter in recent literature. Finally, I examine the role of sacrifice in Kant’s account of Christ as the prototype of pure moral disposition. I conclude by arguing that Kant indeed grasped the importance of including kenotic dynamics in practical philosophy but was somehow unable or unwilling to integrate it into the formal grounding of his ethics. This tension, however, effectively provides an entry point for features that can be found in the post-Kantians.     

Repetitive Intimate Partner Victimization: An Exploratory Application of Social Learning Theory

The research literature on intimate partner violence (IPV) has documented a number of poignant facts that serve as the foundation for this study. First, IPV is prevalent, frequent, and often repetitive. Moreover, repetitive violence within an intimate relationship tends to escalate over time, both in its frequency of occurrence and in its severity. We also know that decisions to leave the relationship do not guarantee that the violence will end. In addition, the phenomenon of “mutual combatancy,” prevalent in many intimate partner relationships, suggests that both parties in this dyadic process co-share the roles of offender and victim. Finally, we know that targets of IPV, like their abusers, tend to disproportionately come from families-of-origin in which violence and aggression were directly and/or vicariously experienced. These facts suggest that one possible starting point for the exploration of repetitive intimate partner victimization (R-IPV) may derive from an inter-generational transmission, or cycle of violence theory, suggested more formally in social learning approaches to criminal and deviant behaviors. The present study examines the extent to which measures of Akers' social learning constructs are able to predict repetitive intimate partner victimization. Self-report data on intimate partner violence among a sample of college students reveal the social learning theory variables, differential association and differential reinforcement in particular, are able to predict both the prevalence and frequency of predict repetitive intimate partner victimization.     

Are good students desirable friends? Evidence for friendship selection among elementary students / ¿Son los buenos estudiantes amigos deseables? Evidencia para la selección de amistad entre estudiantes de educación primaria

Abstract

This study assesses the relationship between friendship networks and academic performance among third graders from one school in Santiago, Chile. Longitudinal social network analysis (RSiena) was used to test whether friendship selection is driven by academic performance and if befriended peers tend to influence each other on their academic performance, including gender as a covariate. Results show a positive relationship between academic performance and number of friendship nominations received, and a higher probability of same-gender friendships. Students with higher academic achievement are more likely to be nominated as friends, especially by peers with lower academic achievement. These results suggest that elementary students value high performance as a desirable characteristic in their friends.     

Looking for unexpected results: the need to systematize the registration of environmental variables / Buscando resultados inesperados: la necesidad de sistematizar el registro de variables ambientales

Abstract

Why is replicating cognitive neuroscience results so difficult? Here we discuss a possible bias that could determine the systematic omission of control variables. A methodology based on the notion that cognitive processes are encapsulated undermines the adequate characterization of both the sample and its experimental context. Systematically exploring the impact of the sample and context variables implies discussing and developing standard experimentation practices. We propose actively searching for unexpected results as a starting point to do so.
