Jealousy protest to a social rival compared to a nonsocial rival in Chilean infants 10-20 months' old.

Jealousy protests have been linked to the intrusion of social rivals challenging infants' exclusive access to maternal care and resources that typically accompany attachment. Previous studies revealed that the experimental presentation of social rivals evokes protest in as early as 6 months old infants. This study replicated research on jealousy protests in a novel language and sociocultural context with 10-20 months old infants.

Short-Term Effects of the Empathic Talk: The Role of Perceived Empathy, Interpersonal Dispositions, and Vagal Tone on Experiencing Depth.

Background: Sexual behavior usually begins in adolescence, and is mediated by biological, personality and socio-cultural variables which can affect the expression of preventive and risky sexual performance, as well as sex and age differences.

Assessment of the behavioral inhibition system and the behavioral approach system: adaptation and validation of the Sensitivity to Punishment and Sensitivity to Reward Questionnaire (SPSRQ) in a Chilean sample.

The goal of the present study is to estimate the psychometric properties of the Sensitivity to Punishment and Sensitivity to Reward Questionnaire (SPSRQ; Torrubia, Avila, Moltó, & Caseras, 2001) in a sample of Chilean college students. The main hypothesis is that the instrument would show appropriate levels of reliability and validity, in light of previous validation studies. A pilot study was conducted in order to generate the adapted version of the questionnaire, which was then applied to a student sample from different undergraduate careers (n = 434).

Exploring the relationship between vagal tone and event-related potentials in response to an affective picture task.

The present study is the first to investigate the relationship between vagal tone level and event-related potentials (ERPs) in adults. Numerous studies have shown a relationship between vagal tone and the individual differences between a variety of psychophysiological, affective, and social outcomes. This suggests that vagal tone can be related to how people process relevant affective social information at the brain level.
