Effects of social networks on cross-cultural adjustment

A total of 221 responses were obtained from a survey of international students in Japan, regarding the facilitative effects of social network formation on their adjustment. Regression analyses were conducted to explore the relationships among four types of adjustment revealed in a preceding study (“general adjustment,”“self-control,”“affiliative” and “dependent”), network size, demographic variables, expected social support, etc. For each adjustment type, predictive variables were identified. Two of the variables that showed network effects on adjustment were Japanese language proficiency and race (Asians vs. Westerners). From these results, it would appear that social network formation does facilitate adjustment, and insight into the effect of adjustment type and demographic variables on network functions was obtained. Furthermore, the actual conditions regarding network formation of international students in Japan were revealed.     

Formation of decagonal and approximant phases in the Al-Ni-Ru system

Al-Ni-Ru alloys with a wide composition range have been synthesized and examined by X-ray and electron diffraction experiments. In this system, two types of decagonal (d) phases are formed, namely basic-type and superlattice-type d phases. Annealing experiments have shown that the basic-type d phase is stable at high temperatures and that its single-phase region is located in a small composition range around Al 75 Ni 15 Ru 10 . On the other hand, the superlattice-type d phase is metastable and has been found to form only in the samples before annealing. Besides the d phases, a high-order crystal approximant phase with lattice parameters a = 99.5 Å and b = 84.6 Å has been found. The structural relation between the approximant phase and the d phase is discussed in terms of a phason tensor.     

Preference‐expectation reversal in the ratings of independent and interdependent individuals: A USA–Japan comparison

We predicted and supported the prediction that a ‘preference‐expectation reversal’ would occur among Japanese but not among Americans. American and Japanese participants evaluated ideal‐typical independent and interdependent persons on the negative–positive dimension, and estimated how others would evaluate these persons. They also indicated their preference for acting like each of the target persons; that is, which of the two target persons they would prefer to act like. Both the American and Japanese participants wanted to act like the typical independent person rather than the typical interdependent person. However, the Japanese participants expected that others would evaluate the interdependent person more positively than the independent person. This preference‐expectation reversal was not observed among the American participants. Further analysis demonstrated that the American participants' personal evaluations of the two targets were consistent with their preferences. The Japanese participants' personal evaluation represented a compromise between their preferences and the expected responses of others. These results suggest that the culturally shared belief in Japan that interdependent persons would receive more positive evaluations than independent persons created an incentive for them to behave interdependently despite their preferences.     

Variations of Gender–math Stereotype Content Affect Women’s Vulnerability to Stereotype Threat

To determine whether variations in stereotype content salience moderates stereotype threat effects, 66 US female undergraduate students were given a standardized math exam, and the salience of specific gender–math stereotype content was manipulated before the exam. Women exerted more effort on each problem and performed better on a math exam when threatened with an effort-based stereotype compared to when threatened with the ability-based stereotype or control (where no stereotype was explicitly mentioned). Implications of these results are discussed in terms of stereotype and social identity threat theory, as well as how the socio-cultural salience of ability versus other components of the gender–math stereotype may impact women who pursue math and science-based domains.     

A study of kinematic cues and anticipatory performance in tennis using computational manipulation and computer graphics

Computer graphics of digital human models can be used to display human motions as visual stimuli. This study presents our technique for manipulating human motion with a forward kinematics calculation without violating anatomical constraints. A motion modulation of the upper extremity was conducted by proportionally modulating the anatomical joint angular velocity calculated by motion analysis. The effect of this manipulation was examined in a tennis situation--that is, the receiver's performance of predicting ball direction when viewing a digital model of the server's motion derived by modulating the angular velocities of the forearm or that of the elbow during the forward swing. The results showed that the faster the server's forearm pronated, the more the receiver's anticipation of the ball direction tended to the left side of the serve box. In contrast, the faster the server's elbow extended, the more the receiver's anticipation of the ball direction tended to the right. This suggests that tennis players are sensitive to the motion modulation of their opponent's racket-arm.     

The effect of number of kanji radical companions in character activation with a multi-radical-display task

The majority of Japanese complex kanji consist of two subword units (radicals), and each radical is differentiated according to its combinability. Radical-type frequency is defined as the number of radical companions (NC) functioning as the number of characters containing that radical. The current study is intended to address the question of whether the NC plays a role in kanji character activation under a multi-radical-display (MRD) instead of a tachistoscopic display. An MRD task was used in which the NC was manipulated and the frequency of use of the whole characters was matched on average across the experimental conditions. Participants were divided into two groups (good knowledge vs poor knowledge) according to the score of a kanji completion task. The participants' task was to select an appropriate combination of radicals to compose a legitimate character under the MRD condition. The poor-knowledge group yielded relatively more errors than did the good-knowledge group in the low-NC condition, whereas the good-knowledge group yielded more errors in the high-NC condition than in the low-NC condition. These results demonstrate the different influences of NC as metaknowledge (tacit knowledge of radical productivity) in both good and poor readers.
