Alexithymia predicts arousal-based processing deficits and discordance between emotion response systems during emotional imagery
Peasley-Miklus, Catherine; Panayiotou, Georgia; Vrana, Scott R. (American Psychological Association, 2016)Alexithymia is believed to involve deficits in emotion processing and imagery ability. Previous findings suggest that it is especially related to deficits in processing the arousal dimension of emotion, and that discordance ...

Effect of self-focused attention on the startle reflex, heart rate, and memory performance among socially anxious and nonanxious individuals
Panayiotou, Georgia; Vrana, Scott R. (1998)The present study examined the effect of self-focused attention on the startle reflex and heart rate and assessed the assumption that socially anxious individuals become self-focused in evaluative situations. Twenty- five ...

Effects of self-focused attention on recognizing previously presented self-relevant and irrelevant stimuli
Panayiotou, Georgia; Vrana, Scott R. (Hellenic Psychological Society, 2007)Self-focused attention elevates individuals’ awareness of the self as an object and directs attentional resources toward it. It facilitates the performance of well learned tasks or the recall of information pertaining to ...

Article
Emotional dimensions as determinants of self-focused attention
Panayiotou, Georgia; Brown, R.; Vrana, Scott R. (2007)Negative emotions, and particularly sadness, have been found to induce self-focused attention among both depressed and normal individuals. However, positive emotion, such as happiness, is sometimes found to have a similar ...

The role of self-focus, task difficulty, task self-relevance, and evaluation anxiety in reaction time performance
Panayiotou, Georgia; Vrana, Scott R. (2004)Self-focused attention has been found to facilitate task performance in some instances and inhibit it in others. Among chronically anxious individuals it appears to consistently hinder performance. Less is known about the ...

A startling absence of emotion effects: Active attention to the startle probe as a motor task cue appears to eliminate modulation of the startle reflex by valence and arousal
Panayiotou, Georgia; Witvliet, CV; Robinson, J. D.; Vrana, Scott R. (2011)Research has shown that during emotional imagery, valence and arousal each modulate the startle reflex. Here, two imagery-startle experiments required participants to attend to the startle probe as a simple reaction time ...
