Title: Validation of normalized pulse volume in the outer ear as a simple 
measure of sympathetic activity using warm and cold pressor tests: towards 
applications in ambulatory monitoring

Abstract: Normalized pulse volume (NPV) derived from the ear has the potential 
to be a practical index for monitoring daily life stress. However, ear NPV has 
not yet been validated. Therefore, we compared NPV derived from an index finger 
using transmission photoplethysmography as a reference, with NPV derived from a 
middle finger and four sites of the ear using reflection photoplethysmography 
during baseline and while performing cold and warm water immersion in ten young 
and six middle-aged subjects. The results showed that logarithmically-transformed 
NPV (lnNPV) during cold water immersion as compared with baseline values was 
significantly lower, only at the index finger, the middle finger and the bottom 
of the ear-canal. Furthermore, lnNPV reactivities (ΔlnNPV; the difference between 
baseline and test values) from an index finger were significantly related to 
ΔlnNPV from the middle finger and the bottom of the ear-canal (young: r = 0.90 
and 0.62, middle-aged: r = 0.80 and 0.58, respectively). In conclusion, these 
findings show that reflection and transmission photoplethysmography are 
comparable methods to derive NPV in accordance with our theoretical prediction. 
NPV derived from the bottom of the ear-canal is a valid approach, which could 
be useful for evaluating daily life stress.

Title: iPhysioMeter: A new approach for measuring heart rate and normalized 
pulse volume using only a smartphone

Journal(書誌情報）: Behavior Research Methods, 45(4), 1272-1278, 2013

doi: 10.3758/s13428-012-0312-z

Abstract: Heart rate (HR) and normalized pulse volume (NPV) are physiological 
indices that have been used in a diversity of psychological studies. However, 
measuring these indices often requires laborious processes. We therefore 
developed a new smartphone program, named iPhysioMeter, that makes it possible 
to measure beat-by-beat HR and ln NPV using only a smartphone. We examined its 
accuracy against conventional laboratory measures. Mental stress tasks were 
used to alter HR and ln NPV in 12 participants. Bland-Altman analyses revealed 
negligible proportional bias for HR and ln NPV or for their change values, 
expressed as ΔHR and Δln NPV. However, a relatively large fixed bias did 
emerge for ln NPV, as well as a small one for Δln NPV, although both were 
within the limits of agreement. These findings suggest that iPhysioMeter can 
yield valid measures of the absolute level of HR and of relative changes in ln 
NPV.

Title:The Cultural Background of the Nonacademic Concept of Psychology 
in Japan: Its Implications for Introductory Education in Psychology
Journal:International Journal of Psychology

doi: 10.1002/ijop.12021

Abstract: No research has empirically explored the non-academic concept 
of psychology itself (implicit theories) in non-
Western cultures despite a widely held belief that this understanding 
differs cross-culturally. This study examined
whether the non-academic concept of psychology among inexperienced 
Japanese students differed from the concept held
by students of other countries. In Japanese, psychology is referred to 
as , which includes the ideographic character
, literally meaning heart. This fact led us to hypothesize that 
psychology will be disproportionately associated with
emotion among Japanese students. Indeed, our findings among Japanese 
students produced a J-curve, indicating that our
prediction was true. We posit that this issue has never been discussed 
in Japan because a majority of people share this
concept of psychology. In our second study, we examined not only 
preference in students' association of intelligence
or emotion but also heart or mind with psychology. Finally, we 
identified whether students' believe that psychology
encompasses both the heart and the mind. We conclude with a discussion 
of the importance of explicitly defining the
non-academic concept of psychology in early psychology education in 
Japan.
