Exogenous orienting of visual-spatial attention in ADHD children.

Visual spatial orienting of attention towards exogenous cues has been one of the attentional functions considered to be spared in ADHD. Here we present a design in which 60 (30 ADHD) children, age: 10.9±1.

Viewing loved faces inhibits defense reactions: a health-promotion mechanism?

We have known for decades that social support is associated with positive health outcomes. And yet, the neurophysiological mechanisms underlying this association remain poorly understood. The link between social support and positive health outcomes is likely to depend on the neurophysiological regulatory mechanisms underlying reward and defensive reactions.

Modulation of the outcome-related negativity associated with nicotine abstinence.

Cue-reactivity studies have shown that when consumers are exposed to a substance-related stimulus, potential tobacco use contributes significantly to craving and motivational drive. Although the motivational response to cues signaling tobacco availability has been widely studied, less is known about physiological reactivity to perceived cigarette availability. The aim of the present study was to examine the outcome-related negativity (ORN) evoked by stimuli that signal potential tobacco use in abstinent and sated smokers.

Filial versus romantic love: contributions from peripheral and central electrophysiology.

A major problem in recent neuroscience research on the processing of loved familiar faces is the absence of evidence concerning the elicitation of a genuine positive emotional response (love). These studies have two confounds: familiarity and arousal. The present investigation controlled for both factors in female university students.

Affective processing of loved familiar faces: integrating central and peripheral electrophysiological measures.

A major problem in the electrophysiological studies of emotional processing linked to recognition of familiar faces is the unambiguous differentiation of effects due to emotional valence, arousal, and familiarity. The present paper summarizes a set of three studies aimed at investigating the affective processing of loved familiar faces using Lang's picture-viewing paradigm, with a special emphasis on teasing apart the individual contributions of affective valence, undifferentiated emotional arousal, and familiarity The results of the three studies support the conclusion that viewing the faces of familiar loved ones elicits an intense positive emotional reaction that cannot be explained either by familiarity or arousal alone.
