Maximum key-profile correlation (MKC) as a measure of tonal structure in music

Tonal structure is musical organization on the basis of pitch, in which pitches vary in importance and rate of occurrence according to their relationship to a tonal center. Experiment 1 evaluated the maximum key-profile correlation (MKC), a product of Krumhansl and Schmuckler’s key-finding algorithm (Krumhansl, 1990), as a measure of tonal structure. The MKC is the maximum correlation coefficient between the pitch class distribution in a musical sample and key profiles,which indicate the stability of pitches with respect to particular tonal centers. The MKC values of melodies correlated strongly with listeners’ ratings of tonal structure. To measure the influence of the temporal order of pitches on perceived tonal structure, three measures (fifth span, semitone span, and pitch contour) taken from previous studies of melody perception were also correlated with tonal structure ratings. None of the temporal measures correlated as strongly or as consistently with tonal structure ratings as did the MKC, and nor did combining them with the MKC improve prediction of tonal structure ratings. In Experiment 2, the MKC did not correlate with recognition memory of melodies. However, melodies with very low MKC values were recognized less accurately than melodies with very high MKC values. Although it does not incorporate temporal, rhythmic, or harmonic factors that may influence perceived tonal structure, the MKC can be interpreted as a measure of tonal structure, at least for brief melodies.     

Effects of prior knowledge and response bias upon recognition memory for a story: Implications for children's eyewitness testimony

Abstract: The present study was designed to evaluate the integration hypothesis and the response bias hypothesis for explaining the fragility of children's eyewitness memory, by varying the plausibility of postevent information and the strength of response bias in recognition tests. Preschool children were told a story in which a boy named Ken saw a housebreaker stealing various objects and the postevent information was also incorporated into the story. The first recognition test was administered immediately following the presentation of an interpolated story, and the second recognition test was administered 10 weeks later. The results indicated that high-plausibility objects tended to be recognized as the stolen objects in the second recognition test, and that recognition accuracy was higher for a new-distractor condition than for a misleading-distractor condition. These findings were interpreted as suggesting that the memory representation of the story might be changed through the integration processes and/or rendered inaccessible in terms of the response bias.     

Toward a culturally anchored ecological framework of research in ethnic-cultural communities

Proposed a research framework (the “cube” model) in which community psychologists working in ethnic-cultural communities can make appropriate decisions on conceptual and methodological issues from a culturally anchored, ecological-contextualist perspective. The intent of the model is to articulate ethnic-cultural heterogeneity in community research by elucidating three metamethodological issues: (a) definition of an ethnic-cultural community, (b) applicability of cross-cultural theories and methods to ethnic-cultural community research, and (c) geographical or ecological stability of an ethnic-cultural community. The model posits that ethnic-cultural community research can be conceptualized as a three-dimensional structure that represents an interaction among research questions, methods, and cultural complexity (referring to the extent to which an ethnic-cultural group is defined in a larger ecological context or community both at the individual and collective levels). Future directions for research were discussed in terms of the utility and the limitations of the proposed research model.     

Mapping Open-Field Behavior in Rats: Applicability Across Sexes

Open-field behavior of female and male Sprague-Dawley rats was plotted on a map using scores derived from a principal-component analysis. As reference points on the map, three treatment conditions were used: electric shock, extensive stroking, and additional trials after habituation to the field. Five measures were used: ambulation, penetration into the inner square, rearing, defecation, and urination. The behaviors in each treatment condition clearly cohered with each other on the map, regardless of sex difference in raw scores. This coherence shows that the nature of the emotional behavior caused by the present treatments is similar across sexes, indicating, to some degree, the applicability of the map across the sexes. The additional experiment (concerning the estrus effect on the open-field behavior) suggests that the estrus effect is not large enough to compromise the validity of the map, which was constructed on the basis of the data without control of the estrus effect.     

Enhancing Cultural Intelligence: The Roles of Implicit Culture Beliefs and Adjustment

Although international experience has been proposed as an important factor contributing to the development of cultural intelligence (CQ), its effect on CQ has often been assumed. Through a contact hypothesis framework, this study advances our understanding of CQ. It examines the process through which CQ changes occur against the backdrop of international exchanges. University students who were enrolled in an international exchange program with partners worldwide participated in this study. Using a 3‐wave time‐lagged design, we found that implicit culture beliefs (the beliefs about fixedness or malleability of cultural attributes) influenced intercultural rejection sensitivity, which impacted the cross‐cultural adjustment of sojourning students and their subsequent CQ. Specifically, we found that cross‐cultural adjustment experiences, particularly in the social domain, play an important role in influencing CQ. Findings from this study raise novel research questions and underscore the need for more empirical work in this area. Theoretical and practical implications are discussed.     

The role of goal orientation during expatriation: a cross-sectional and longitudinal investigation

Using cross-sectional and longitudinal data from expatriates in China, the authors investigated the roles of general, work, and interaction adjustment, as well as work stress, as mediators between the antecedents (learning, proving, and avoiding goal orientations, and perceived organizational support) and expatriate outcome (job performance and premature return intention) relationships. Results indicated that goal orientations toward overseas assignments had differential relationships with expatriate job performance and premature return intention. In addition, it was found that these relationships were partially mediated by expatriate adjustment facets. Implications for expatriate adjustment research and practice are discussed.     

The Psychological Cost of Racial Discrimination: What is the Role of Residential Segregation?

Racial discrimination is known to harm health, but to what extent the health burden of racial discrimination is contingent on residential contexts is understudied. This study examines the moderating role of racial residential segregation in the relationship between racial discrimination and psychological distress. Nationally representative data from the 2002–2003 National Latino and Asian American Study were merged with metropolitan-level data from the U.S. Census. Logistic regression models were used to test the independent and joint contributions of racial discrimination and residential segregation to psychological distress among Asians and Latinxs, stratified by nativity status. Higher residential segregation (measured by the interaction index) is associated with lower odds of distress among U.S.-born Asians but not among other groups. As for the moderating effect, residential segregation exacerbates the positive association between discrimination and distress among foreign-born Asians (measured by the dissimilarity index) and foreign-born Latinxs (measured by the interaction index), but not among their respective U.S.-born counterparts. Taken together, the present study highlights that strategies to mitigate the psychological burden of racial discrimination need to move beyond individual-level efforts to incorporate neighborhood-based approaches. In particular, results provide empirical support for efforts to reduce residential segregation, particularly among immigrants who are discriminated against.     

Ethnic minority adolescents and the use of community mental health care services

Examined the utilization rates, treatment dropout rates, and length of treatment for minority adolescents in the mental health care system. Data from the Los Angeles County Department of Mental Health from 1983 to 1988 were used. Ss were 853 African Americans, 704 Asian Americans, 964 Hispanics, and 670 whites. Analyses showed that Asian Americans and Hispanics are underrepresented in existing public mental health facilities while African Americans are overrepresented. For dropout rates, no ethnic differences are found between minority groups and whites; but, for length of treatment, Asian Americans tend to stay longer in treatment while African Americans tend to stay in treatment for a shorter period of time than whites. African Americans also have more outpatient episodes than whites. Implications of the results are discussed, and recommendations for future research are suggested.
