Eysenck’s PEN and Strelau’s RTT theories are considered interrelated on the level of traits and translatable on the level of four ancient temperament types. However, they refer to different ways of regulation stimulation, by content (emotional and social) and by the formal (energetic and temporal) characteristics of activity, respectively. Thus, by indexing behavioral and cortical patterns of response, it was predicted that PEN- and RTT-relevant pairs of temperaments would be associated with specific attentional mechanisms. One week after administration of the FCB-TI and EPQ-R, subjects (260) performed the Emotional Go/No Go task while a 32-channel EEG was being recorded. They were instructed to respond to threatening, sad, or friendly faces, respectively, but not to any other facial expression. A range of ERP components responsive to facial stimuli were investigated. According to behavioral and cortical patterns of response, it was shown that PEN- and RTT-related pairs of temperament types were connected with effective functioning of the anterior and posterior attentional system, respectively. On the behavioral level, significant differences in attentional processing of facial affect were registered in PEN sanguines versus RTT sanguines and PEN melancholics versus RTT melancholics, while on the cortical level significant differences were registered in PEN melancholics versus RTT melancholics and PEN phlegmatics versus RTT phlegmatics. Given these results, the theoretical relations between the PEN and RTT – with particular respect to cognitive and cortical mechanisms underlying temperament types – are discussed.
Presented studies investigated the specificity of visual and auditory modalities in attentional processing of emotion, and its association with temperamental dimensions and trait-like attentional control (AC). During preliminary study 30 participants were presented with the paper-pencil visual search task (Emotional Faces Attentional Test) and emotional prosody detection tasks (Emotional Prosody Test). Results revealed visual happiness superiority and auditory sadness superiority. During the main study, in addition to attentional performance, 51 subjects were administrated two questionnaires: EPQ-R and Attentional Control Scale. Introducing individual differences into analysis limited the general pattern of modality distinctiveness in attentional processing of emotional stimuli obtained in the preliminary study. Findings for all personality traits studied separately showed that Extraversion and low Neuroticism were associated with the visual sadness superiority. Whereas interactional analysis indicated effective visual threat processing in extraverts with good AC and effective friendly prosody detection when Neuroticism and AC remain in inverse relationship. Hence, we have found that processing emotional targets in both modalities is associated with temperament dimensions and their interactions with attentional control. Additionally, findings from both studies suggest that general psychological laws might be challenged by individual differences.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
