Res Psychother 2019 Dec 19;22(3):410. Epub 2019 Dec 19.

Department of Educational Sciences, Section of Psychology, University of Catania, Italy.

To define boundaries and links between research and training in psychotherapy we have to establish what kind of research is needed for this purpose. For defining psychotherapy as a science some basic epistemological premises should be affirmed and specific methods have to be devised, using both quantitative and qualitative approaches, diachronic and longitudinal perspectives, cumulative and meta-analytic strategies, focusing both the techniques used in the therapies and the relationship between the subject and the subject as a core mean for produce change. What should be evaluated in this research process, what methods and techniques of assessment should be preferred, what analyses of data are suitable: these are the main issues addressed in the article, as they are useful for planning the training of a therapist as a researcher, regardless of the privileged theoretical and technical approach.

Distinguishing the Neural Correlates of Perceptual Awareness and Postperceptual Processing.

J Neurosci 2020 06 14;40(25):4925-4935. Epub 2020 May 14.

Department of Psychology, Reed College, Portland, Oregon 97202-8199

To identify the neural correlates of perceptual awareness, researchers often compare the differences in neural activation between conditions in which an observer is or is not aware of a stimulus. While intuitive, this approach often contains a critical limitation: to link brain activity with perceptual awareness, observers traditionally report the contents of their perceptual experience. However, relying on observers' reports is problematic because it is difficult to know whether the neural responses being measured are associated with conscious perception or with postperceptual processes involved in the reporting task (e.
