2028.72 Ontogenetic adaptation of behavioral development in post-weaning pre-juvenile rats,
Kunio Miyamoto, Tokai Women's University, Japan
Several aspects of behavioral development were examined in rats. Food hoarding of 30-day-old
rats was at the lowest level, facilitated by hunger. Crickets-predation was best performed in
30-days rats. Runway emergence and responsiveness to aversive stimuli (electric shocks and loud
noises) of the same age rats suggests that they were less emotional. The performances of radial
maze learning of these rats were at the lowest level, showed active responding strategy, different
from other age rats. These findings suggest the ontogenetic adaptation of post-weaning,
pre-juvenile rats in terms of general tendency as well as specific behavioral properties.
2028.73 The advantages and limitations of ERP in lie detector tests, Hongguang Liu 1 , Zhou
Lin 2 , 1 Chinese People’s Public Security University, China; 2 Capital Normal University, China
n the view of psychological measure, based on ERP’s review of research literatures, this article
introduces the theories and techniques of traditional polygraph briefly, and then discusses the
problems on research of ERP in the polygraph, as follow: (1) the representativeness of analog
studies about the criminal photo/word of question sentence and veracity of criminal field studies,
(2) in ERP and polygraph, high incidence of false-positive classifications due to instandardization,
(3) what are the criterions and improvement of reliability and validity of ERP in the polygraph. it
suggests the trend on the research of ERP in the traditional polygraph.
2028.74 Song-induced ZENK gene expression in the brain of female budgerigars, Suteo
Yamazaki, Hiroko Eda-fujiwara, Ryohei Satoh, Takenori Miyamoto, Shuzo Ohi, Japan
Women's University, Japan
In male songbirds, vocal- and auditory-related neuronal activity produces rapid expression of an
immediate-early gene, ZENK, after exposure of conspecific song. Little is known about this in
case of females, however, so we analyzed the expression of the Zenk protein caused by
conspecific male song stimuli in many forebrain regions of female budgerigars. Marked Zenk
protein expression was observed in the caudomedial auditory-related centers, such as fields L1 and
L3, the caudomedial neostriatum and so forth. Zenk protein expression in these brain structures
may be associated with the mechanism of auditory perceptional processing of conspecific male
songs.
2028.75 Tree shrews Tupaia belangeri and Rats (Rattus norvegicus) abstract transitive relation in
context of transitive inference, Makoto Takahashi, Tomokazu Ushitani, Kazuo Fujita, Kyoto
University, Japan
Tree shrews and rats were trained A+B, B+C, C+D, D+E with a modified radial maze which had 8
arms labeled A through H from one end. After training, animals were tested with FH in
Experiment 1, and FGH in experiment 2. In Experiment 3, all one step combinations were tested
with reversed apparatus in term of south-north orientation. Some tree shrews and rats showed
transitive responding. These results suggested that tree shrews and rats could abstract transitive
relation, and apply it to novel situation.
