Test-retest reliability and practice effects of the Wechsler Memory Scale-III

Although serial administration of cognitive tests is increasingly common, there is a paucity of research on test-retest reliabilities and practice effects, both of which are important for evaluating changes in functioning. Reliability is generally conceptualized as involving short-lasting changes in performance. However, when repeated testing occurs over a period of years, there will be some longer lasting effects. The implications of these longer lasting effects and practice effects on reliability were examined in the context of repeated administrations of the Wechsler Memory Scale-III in 339 community-dwelling women aged 40-79 years over 2 to 7 years. The results showed that Logical Memory and Verbal Paired Associates subtests were consistently the most reliable subtests across the age cohorts. The magnitude of practice effects varied as a function of subtests and age. The largest practice effects were found in the youngest age cohort, especially on the Faces, Logical Memory, and Verbal Paired Associates subtests.     

Psychometric Properties and Convergent Validity of the Dependency-Oriented and Achievement-Oriented Psychological Control Scale (DAPCS) with Italian Adolescents

This study is aimed to validate the Italian version of the dependency-oriented and achievement-oriented psychological control scale (DAPCS), a self-report questionnaire designed to assess the adolescent’s perception of the two dimensions of psychological control. In Study 1, we assessed factorial validity and reliability of the Italian version of DAPCS with a sample of adolescents. In Study 2, we examined the convergent validity of the Italian version of the DAPCS analyzing the associations between the two domains of psychological control and well-established measures related to them such as strictness/supervision, overprotection, non dependency on parents, and family functioning. Confirmatory factor analyses confirmed the hypothesized two-factor solution of the DAPCS, with a 16 items’ version better fitting the data, for paternal as well as for maternal ratings. High indices of internal consistency indicated that both subscales produced reliable scores. Convergent validity was confirmed by positive associations between the DAPCS’ subscales and measures of strictness and negative associations between the DAPCS’ subscales and measures of global family functioning, both for maternal and paternal ratings. Finally, results evidenced significant effects for adolescents’ and parental gender on achievement-oriented psychological control, with mothers rated higher than fathers by males and fathers rated higher than mothers by females. Overall, the results of these studies indicated that the Italian form of the DAPCS might be a useful instrument to assess the two domain-specific types of parental psychological control among Italian-speaking adolescents.     

Explaining Black–White differences in homicide victimization

In recent decades, homicide has so truncated life expectancy in the United States that homicide victimization should be considered a public-health problem worthy of addressing via preventive programs and policies. Evidence in the literature roots homicide victimization deep within the social structure, in problematic social inequalities and disadvantages. The evidence suggests homicide victimization is associated with six demographic, social, and lifestyle factors: being male, African-American, young, of low socioeconomic status, without adequate social support, and mentally ill or a substance user. Taking an interdisciplinary approach, this paper outlines theoretical mechanisms leading to racial differences in homicide victimization. It hypothesizes that Black Americans (a) are likelier than Whites to become homicide victims and, if victimized, (b) are likelier to be younger than victimized Whites. To understand these racial differences, the paper examines whether and how multiple disadvantages—at both the macro and micro level—operate against Blacks disproportionately. The paper concludes by noting further research needs and policy implications.     

Music,identity, and musical ethnocentrism of young people in six Asian,Latin American,and Western cultures

Ethnomusicologists and sociologists have extensively discussed the symbolic role of music in the creation, maintenance, and expression of cultural and national identity, while the underlying social psychological processes remain unexplored. We elaborate psychological mechanisms of identity construction and identity expression through culture‐specific music preferences. We propose and test a model linking music preferences to national identity via musical ethnocentrism in six student samples from Brazil, Germany, Hong Kong, Mexico, New Zealand, and the Philippines. In each context, culture‐specific music styles were related to national identity of its listeners and musical ethnocentrism mediated these effects. This paper bridges culture‐specific and universal perspectives on music and identity by examining the underlying psychological processes in Asian, Latin, and Western cultures.     

Interrelationships between anxiety,lifestyle self-reports and fitness in a sample of Hong Kong University students

Although anxiety in university students has been well documented, the influence of lifestyle and fitness status in relation to anxiety has not been investigated from a cultural perspective previously. To make recommendations regarding the avoidance or management of anxiety in this anxiety-prone cohort that are rationally based, this preliminary investigation examined the interrelationship between anxiety, lifestyle self-reports and aerobic fitness in Hong Kong Chinese University students. The State Trait Anxiety Inventory (Form Y-2) and a lifestyle questionnaire were completed by 213 students. Female students were more anxious than male students. Subjects with high anxiety reported more deleterious lifestyle behaviours including higher salt consumption and lower levels of exercise; in addition to more frequent symptoms of anxiety such as headaches and daytime somnolence. The extremes of this sample were stratified into a low anxiety group (n = 17) and a high anxiety group (n = 14) to compare their fitness status. Although both groups had below normal aerobic capacity, the higher systolic blood pressure observed for the high anxiety group is consistent with signs of anxiety, or greater deconditioning in this group or both. The results of this study have highlighted anxiety as a concern in Hong Kong University students and identified some lifestyle and fitness correlates. Understanding lifestyle and pathophysiological correlates of anxiety in Hong Kong University students that may have a cultural basis, is a crucial step toward averting or managing anxiety when these students are studying either in Hong Kong or abroad.     

Taiwanese employees' justice perceptions of co-workers' punitive events

The authors examined justice perceptions of Taiwanese employees in response to co-workers' punitive events (punishment by a superior). They developed a hypothesis based on Chinese indigenous wu-lun principles and the concept of empathy. Results of the study showed that perceived vertical (between superior and subordinate) and horizontal (between subordinates) relationships jointly affected justice perceptions. Respondents who perceived low (negative) leader-member exchange with the superior and high (positive) liking of the punished person showed the lowest justice perceptions. In conclusion, the authors note that comparative analysis of organizational justice is a promising direction for future research.     

“Not me” consumer justifications for not reporting suspected price-fixing activities: Neutralization techniques & counterstrategies

Price-fixing, an anti-competitive activity by firms, raises consumer prices, limits consumer choices, and violates the law. Drawing on the neutralization theory, this study aims to investigate consumer participation in anti-price-fixing efforts. This is important as the government's strategy of combating price-fixing often relies on tip-offs from the public. Accordingly, this study examines consumer willingness to come forward to file a complaint of suspected price-fixing cases to authorities and the justifications provided by participants for their reluctance. Focus group interviews were conducted with twenty-three participants. The findings revealed that although the participants agreed that price-fixing is unethical and unjust, they were reluctant to file a complaint to report suspected price-fixing activities to authorities. This study makes theoretical contributions to uncover five neutralization techniques used by the participants to reconcile their negative feelings. Three new counterstrategies have not been explored or discussed in previous studies. This contributes to a new line of inquiry about consumer responses to price-fixing.     

Alcohol and Other Drug Use Among African-American Students in a Southern University

This analysis of the circumstances of alcohol and other drug use among African-American students at a predominantly White university indicated that the majority of these students drank in a responsible manner. Other drug use was almost nonexistent. Strong peer disapproval was exhibited toward drug users and alcohol abusers. Counselors dealing with such problems must be cognizant of the multicultural aspects of these behaviors.     

记忆与学习的脑化学研究 Ⅱ.海马内注射胰蛋白酶与胰凝乳蛋白酶对大白鼠暗箱迴避模式记忆的影响

本实验选择了胰凝乳蛋白酶与胰蛋白酶,它们同属水解酶,能够内切蛋白质与肽类底物的某些键位。26只刚成年的雄性大鼠分作三组:生理盐水/不巩固组(NS/NC)、胰蛋白酶/不巩固组(T/NC)与胰凝乳蛋白酶/不巩固组(CT/NC)。 实验结果表明,双侧海马内注射(AP_2L_2H_4与AP_4L_3H_5)胰凝乳蛋白酶与胰蛋白酶后,对暗箱廻避(DBA)模式记忆有不同的影响。胰蛋白酶注射后,该记忆保持明显降低,而胰凝乳蛋白酶注射后仍可巩固。所用的实验剂量大致为半致死剂量的三分之一。
