[Presence/absence of original information in the misleading information effect: an investigation using recognition and priming tasks similar to original information presentation].

Several previous studies on the misleading information effect employed priming tasks to examine the presence/absence of original information. Given hyperspecificity of priming, however, it is questionable whether or not their priming tasks were sensitive enough to detect original information because their stimuli were perceptually different from the slides in the study phase. In the priming task of this research, we used slides whose perceptual properties were equivalent to those of the studied ones.

[A Japanese perception of self and others: self-critical and other-enhancing biases].

Previous research has found that Japanese people make relatively critical appraisals of themselves while their appraisals of others are relatively flattering. In order to find the conditions under which these two evaluation biases occur, 144 Japanese undergraduates were first asked to list ten attributes of theirs and then to rate the desirability of possessing each of them (self judgment). Next, someone else in the same class rated the desirability of each (other judgment).

[Effects of rotation and distortion on perceptual priming].

We conducted two experiments to specify the properties of the representation underlying perceptual priming. We transformed a particular property of stimuli between study and test. We used novel stimuli to eliminate contamination by semantic memory.

Hair cell damage and recovery following chronic application of kanamycin in the chick cochlea.

Three-day old chicks were given kanamycin at a dose of 200 mg/kg/day for 10 days and their cochleae were processed for scanning electron microscopy at 1, 3, 7 and 14 days following the last injection. Both hair cells and supporting cells were damaged by kanamycin in the basal 35% of the basilar papilla. By 14 days post-treatment, however, most of the damaged region had been replaced with regenerating hair cells and supporting cells.

Kanamycin induced low-frequency hearing loss in the budgerigar (Melopsittacus undulatus).

The chronic effects of kanamycin (KM) on hearing in the budgerigar were investigated by behavioral audiometry. The birds received a daily intramuscular injection of KM (100 mg/kg or 200 mg/kg) for 10 successive days, and absolute thresholds between pre- and post-treatment were compared. KM induced both transient and permanent low-frequency specific hearing loss; i.

Frequency specific susceptibility to acoustic trauma in the budgerigar (Melopsittacus undulatus).

The effects of intense noise exposure on hearing in the budgerigar were examined by behavioral audiometry. After binaural exposure to an intense broadband noise, auditory threshold shifts (TS) of the birds were continuously measured at frequencies between 0.125 and 8 kHz using an avoidance conditioning technique.
