Alexithymia and sociocultural factors in a Japanese sample: a study with the Rorschach

We reexamined the Japanese version of the 20-item Toronto Alexithymia Scale, a self-report sc ale for measuring alexithymic characteristics, by comparing the scores on three factors and the total scores with variables of the Rorschach in a sample of 40 (originally 48) Japanese college students. Based on prior studies, our aims were to further validate the 20-item Toronto Alexithymia Scale by comparing its scores with those on a projective technique. We also investigated whether sociocultural factors, such as repression of hostility. are associated with scores on the 20-item Toronto Alexithymia Scale (especially Factor 3). None of the seven Rorschach Alexithymia Variables were significantly related to the factors and total scores of the 20-item Toronto Alexithymia Scale. However, scores for Factor 1 (difficulty identifying feelings) of the 20-item Toronto Alexithymia Scale correlated positively with scores on Sum C' (reserved responses to emotional stimuli) and Adj es (stimulus demand), suggesting that individuals who score high for Factor 1 experience gloomy, depressive feelings but in constricted ways. Scores for Factor 3 (externally oriented thinking) correlated positively with the D scores (stress tolerance) and negatively with m (situational stress) responses, suggesting that Factor 3 may reflect a psychological defense that enhances stress tolerance. There was a nonsignificant negative correlation between Factor 1 and Factor 3 scores, but, unlike our hypothesis. Factor 3 was neither related to AG (aggression) nor S (space responses reflecting oppositional tendency), indices of aggression or hostility in the Rorschach Comprehensive System. It may be that the 20-item Toronto Alexithymia Scale and the Rorschach measure quite different aspects of personality, but further research is necessary.     

The processing of constituent characters in Kanji words in proofreading Japanese sentences

In two proofreading experiments the processing of constituent characters in Japanese words was studied. In Experiment 1, the subjects were asked to detect misspellings on a CRT displaying a character, a word, a phrase, or a full sentence at a time. In Experiment 2, a comprehension task was added to make sure that the subjects read sentences in left-to right fashion with comprehension. Both experiments showed consistent results. The manipulation of visual similarity between misspelled and correct characters revealed that misspellings having supraletter features nearly identical to the correct characters received lower detection rates, and that the subjects utilized word-level information when proofreading. The disruptive effect on character processing in reading a sentence that was expected from the unitization hypothesis (Healy & Drewnowski, 1983) was not found. The constituent-level units in Japanese words are considered to be functionally equivalent to word-level units, instead of constituting a hierarchy.Part of this research was presented at the Second International Conference on Visual Search, Durham, U.K., September 1990     

Sex differences in interruption: An experimental reevaluation

Two experiments were conducted to assess the validity of previously reported sex differences in the frequency of interruptions during a dyadic conversation. In both experiments, 24 undergraduates (12 male, 12 female) were randomly paired with previously unacquainted partners out of the sample to create eight same-sex pairs and four cross-sex pairs. Each pair's discussion was secretly tape-recorded and later analyzed for two measures of interruption: rate of interruption and percentage of interruptions initiated by each speaker. Experiment 1 and 2 differed in the setting in which the conversations took place. The first experiment was conducted in a casual setting, and the latter in a laboratory setting. Contrary to previously reported findings, a tendency for females to interrupt males more than vice versa for both measures of interruption was revealed in Experiment 1. However, in Experiment 2, males were found to interrupt somewhat more than females. Finally, a highly significant interaction effect of setting was found, which suggests that there may be cause to believe there is a differential setting effect for males and females in the various groups.The present experiments were conducted while the author attended the University of Toronto as an undergraduate student in the departments of psychology and anthropology. The author would like to extend special thanks to professors R. M. Bagby, I. Kalmar, and P. A. Reich for their advice in conducting both experiments, and to professor G. E. MacKinnon and for his valuable comments in revising the present paper. Finally, many special thanks go to professor K. Bloom, Ms. W. Chan, M. Lo, N. Mohan, and V. Okazawa for their enormous support and encouragement throughout the study.     

Ecological Effects in Cross‐Cultural Differences Between U.S. and Japanese Color Preferences

We investigated cultural differences between U.S. and Japanese color preferences and the ecological factors that might influence them. Japanese and U.S. color preferences have both similarities (e.g., peaks around blue, troughs around dark‐yellow, and preferences for saturated colors) and differences (Japanese participants like darker colors less than U.S. participants do). Complex gender differences were also evident that did not conform to previously reported effects. Palmer and Schloss's (2010) weighted affective valence estimate (WAVE) procedure was used to test the Ecological Valence Theory's (EVT's) prediction that within‐culture WAVE‐preference correlations should be higher than between‐culture WAVE‐preference correlations. The results supported several, but not all, predictions. In the second experiment, we tested color preferences of Japanese–U.S. multicultural participants who could read and speak both Japanese and English. Multicultural color preferences were intermediate between U.S. and Japanese preferences, consistent with the hypothesis that culturally specific personal experiences during one's lifetime influence color preferences.     

Biases and regularities of grapheme–colour associations in Japanese nonsynaesthetic population

Associations between graphemes and colours in a nonsynaesthetic Japanese population were investigated. Participants chose the most suitable colour from 11 basic colour terms for each of 40 graphemes from the four categories of graphemes used in the Japanese language (kana characters, English alphabet letters, and Arabic and kanji numerals). This test was repeated after a three-week interval. In their responses, which were not as temporally consistent as those of grapheme–colour synaesthetes, participants showed biases and regularities that were comparable to those of synaesthetes reported in past studies. Although it has been believed that only synaesthetes, and not nonsynaesthetes, tended to associate graphemes with colours based on grapheme frequency, Berlin and Kay's colour typology, and colour word frequency, participants in this study tended in part to associate graphemes with colours based on the above factors. Moreover, participants that were nonsynaesthetes tended to associate different graphemes that shared sounds and/or meanings (e.g., Arabic and kanji numerals representing the same number) with the same colours, which was analogous to the findings in Japanese synaesthetes. These results support the view that grapheme–colour synaesthesia might have its origins in cross-modal association processes that are shared with the general population.     

Mood and recall of autobiographical memory: the effect of focus of self-knowledge

Mood state facilitates recall of affectively congruent memories (i.e., mood-congruent recall). Mood state may also promote motivation to alleviate a negative affective state, leading to retrieval of affectively incongruent memories (i.e., mood incongruent recall). The present study demonstrates that the focus of self-knowledge influences the occurrence of both mood-congruent recall and mood-incongruent recall. Three experiments found that mood-congruent recall occurred when participants recalled their experiences from a self-aspect that was related to the elicitor of moods, whereas mood-incongruent recall occurred when they recalled their experiences from a self-aspect that was unrelated to the elicitor of moods. These results suggest that the nature of the self-aspect from which persons recall their experiences determines whether mood-congruent or mood-incongruent recall occurs.     

Acquisition of the Meaning of the Word Orange Requires Understanding of the Meanings of Red,Pink, and Purple: Constructing a Lexicon as a Connected System

This research investigated how children build up the language-specific system of the color lexicon, examining factors that play important roles for the construction of an adult-like color lexicon. We had 3-, 4-, and 5-year-old Japanese-speaking children and adults (n = 20, 18, 19, and 19, respectively) produce names for 93 color swatches. The results showed that children of all ages were able to apply most of the chromatic words to the colors close to the center of each category, but even 5-year-olds struggle to delineate the boundaries between the words. Furthermore, the model analyses revealed that broad-covering and high-frequency words are mapped to the center of the lexical category earlier. However, cross-individual consistency in adults' use contributed most strongly for the adult-like boundary delineation. The results suggest that the process of system construction consists of at least two steps (i.e., mapping words to their category center and finding appropriate boundaries between neighboring words), with the quantity and the quality of the input contributing differently to the steps.
