Lateralized Difference In Tympanic Membrane Temperature: Emotion And Hemispheric Activity, Ruth E. Propper, Tad T. Brunyé
Lateralized Difference In Tympanic Membrane Temperature: Emotion And Hemispheric Activity, Ruth E. Propper, Tad T. Brunyé
Ruth Propper
We review literature examining relationships between tympanic membrane temperature (TMT), affective/motivational orientation, and hemispheric activity. Lateralized differences in TMT might enable real-time monitoring of hemispheric activity in real-world conditions, and could serve as a corroborating marker of mental illnesses associated with specific affective dysregulation. We support the proposal that TMT holds potential for broadly indexing lateralized brain physiology during tasks demanding the processing and representation of emotional and/or motivational states, and for predicting trait-related affective/motivational orientations. The precise nature of the relationship between TMT and brain physiology, however, remains elusive. Indeed the limited extant research has sampled different participant populations …
Superior Episodic Memory Is Associated With Interhemispheric Processing, Ruth E. Propper, Stephen D. Christman
Superior Episodic Memory Is Associated With Interhemispheric Processing, Ruth E. Propper, Stephen D. Christman
Ruth Propper
The dependence of episodic memories on interhemispheric processing was tested. In Experiment 1, positive familial sinistrality (FS+; e.g., the presence of left-handed relatives) was associated with superior episodic memory and inferior implicit memory in comparison with negative familial sinistrality (i.e., FS-). This reflected a greater degree of interhemispheric interaction in FS+ participants, which was hypothesized as facilitating episodic memory. In Experiment 2, the authors directly manipulated inter- versus intrahemispheric processing using tests of episodic (recognition) and semantic (lexical decision) memory in which letter strings were presented twice within trial blocks. Semantic memory was superior when the 2nd presentation went to …
