Little is known about the neural mechanisms that underlie tuning to the native language(s) in early infancy. Here we review language tuning through the lens of type and amount of language experience and introduce a new manner in which to conceptualize the phenomenon of language tuning: the relative speed of tuning hypothesis. This hypothesis has as its goal a characterization of the unique time...

Distinguishing between slow brain potential correlates of arousal and activation on the basis of their functional role and temporal involvement during a reaction-time task, data are presented which suggest that weak electrical polarizing currents applied to the head in human subjects modify predominantly activation indicators rather than arousal ones.

A fundamental characteristic of a text is that its sentences are not unrelated but cohere. To understand a text, a reader must therefore cognitively establish specific relations between a new statement and the previously read text. The coherence between sentences can be established by different kinds of integration processes: anaphora resolution, memory processes that resonate for words with re...

Resilience research has usually focused on identifying protective factors associated with specific stress conditions (e.g., war, trauma) or psychopathologies (e.g., post-traumatic stress disorder [PTSD]). Implicit in this research is the concept that resilience is a global construct, invariant to the unfavorable circumstances or the psychopathologies that may develop (i.e., the mechanisms under...

Anticipation for future affective events and prediction uncertainty were examined in healthy controls and individuals with dysthymia (DYS) using behavioral responses and the contingent negative variation (CNV) and post-imperative negative variation (PINV) event-related potential (ERP) components. Warning stimuli forecasted the valence of subsequently presented adjectives ("+", positive; "=", ne...

We studied behavioral indicators of poor welfare in shelter dogs. Our research question was: How is the welfare of shelter dogs affected by length of stay at a shelter, age, sex, and breed? Data were collected on 18 dogs from October 2016 to March 2017 at a small private shelter in Marietta, GA. Data were collected in 15-minute sessions when the dogs were in their indoor enclosures. No signific...

Accurate pain assessment in preterm infants in the neonatal intensive care unit (NICU) is complex. Infants who are born at early gestational ages (GA), and who have had greater early pain exposure, have dampened facial responses which may lead to under-treatment. Since behavioral and physiological responses to pain in infants are often dissociated, using multidimensional scales which combine th...
