Key issues are the cognitive architecture and mental chronometry
of appraisal, neurophysiological structures of relevance and valence detection, the emergence of conscious feelings due to the synchronization of brain/body systems, the generating mechanism for motor expression, the dimensionality of affective space, and the role of embodiment and empathy in perceiving and interpreting emotional expressions.
Scientists have long made use of mental chronometry (Jensen, 1985).
Mental chronometry in the study of learning disabilities.
Application of the techniques of mental chronometry to the study of learning disabilities.
Mental chronometry was important for both scientific and
The accuracy of mental chronometry was not improved on
Of course, Jensen was not the first to address these ideas and his own accounts (Jensen, 1982a; 1987a; this issue) of the beginnings of his involvement with mental chronometry
provide informative historical background to his research.
and individual differences in cognitive processes: Common pitfalls and their solutions.
While the phenomenological aspect of the detection/identification distinction no longer plays a role in mental chronometry, the notion that it provides a reliable basis for distinguishing simple from choice reactions still has its adherents.
However, the pioneers of mental chronometry were not entirely insensitive to the importance of distinguishing the IS from background noise.
If mental chronometry has its behavioural branch in the study of reaction times, the burgeoning of electroencephalographic investigations of event-related brain potentials (ERPs) in the mid-1960s (e.
In the second chapter, Posner's studies on mental chronometry
are described in straightforward terms, and the reader is introduced to the idea of modelling behaviour in terms of cognitive processes.
