Human reconsolidation does not always occur when a memory is retrieved: the relevance of the reminder structure

Memory reconsolidation is defined as a process in which the retrieval of a previously consolidated memory returns to a labile state which is then subject to stabilization. The reminder is the event that begins with the presentation of the learned cue and triggers the labilization-reconsolidation process. Since the early formulation of the hypothesis, several controversial items have arisen concerning the conditions that define reconsolidation. It is herein proposed that two diagnostic features characterize reconsolidation, namely: the labilization of the reactivated memory and the specificity of the reminder structure. To study this proposal, subjects received two different training sessions on verbal material on Day 1 and Day 2, respectively. Finally, they were tested for the first and second acquired memories on Day 3. It is demonstrated that the human declarative memory fulfills the two requirements that define the process. First, the reactivated memory is impaired by a new learning only when it is given closely after the reminder, revealing that the memory is labilized. Second, the omission of at least one of the reminder's components prevents labilization. Therefore, results show that the new learning fails to produce an amnesic effect on the target memory either when the reminder omits the learned cue or includes the beginning of the reinforcement.     

A method for the control of eating rate: A potential intervention in eating disorders

A method for the control of eating rate gave subjects feedback from a computer screen on how much and at what rate to eat during a meal. The method also allowed us to record the development of satiety during the meal. Linear eaters—that is, women selected for eating at an approximately constant rate—underate when challenged to eat at a lower rate and overate when challenged to eat at a higher rate, thereby modeling the eating behavior of patients with anorexia nervosa and binge eating disorder, respectively. In both cases, the women’s postmeal perception of satiety mimicked that of the respective patient group. The results provide support for the notion that linear eaters have the capacity to exhibit disordered eating.     

Two Case Studies of Community Schools Serving Latino and Southeast Asian Children

Recent attention has focused on establishing school-based integrated services centers which offer educational and noneducational services to students and their families. We present two comparative case studies of client participation in school centers established in low income Latino and Southeast Asian communities. The cases focus on types of center services utilized by families, culturally compatible practices of the centers, and impact of coordinated services on students and families. The data reveal the limited capacity of high poverty families to cope with daily and persistent life challenges and how the schools have been transformed into family support environments which assist families to manage their lives in ways that lead to self-sufficiency and growth.     

AN ACQUAINTANCE RAPE PREVENTION PROGRAM

The present study investigated the effects of an acquaintance-rape prevention program on college students' attitudes toward rape and attitudes toward women, perceptions of acquaintance-rape scenarios, and rape empathy. Participants were led to believe that they were participating in two separate experiments in order to decrease demand characteristics. Results indicated that intervention group men and women became more empathic toward the victim than the control group, postintervention. Within the intervention group, men changed more in their attitudes toward women postintervention than did women. In addition to positive attitude change, results with the date-rape scenarios suggested that intervention-group men became more certain of their definitions of rape situations postintervention. Prior to the intervention, women were generally more certain of their definitions than were men, with intervention-group men approximating women's responses postintervention.     

A Challenge to the Integrity of Creation: An African Woman's Perspective

Is JPIC a compelling process calling churches and Christians to commitment and involvement within the life of the world? Or, as some critics claim, is JPIC a rather a handy but not too practical theoretical construct within which to house the various environment and development commitments of the ecumenical movement? These are ongoing and helpful questions which are not new to the JPIC process. They are important, and necessary to keep in the forefront of debate and discussions in churches, for they point to a central truth — that JPIC is effective only to the extent that it makes a difference in the lives of people. The wealth of theological reflection and socio-political assessment of the JPIC process, as evidenced by the articles of this issue of The Ecumenical Review, are meaningful precisely in relation to their capacity to form and inform the understandings and actions of churches and Christians in the world. For in the last analysis, JPIC can only be measured in terms of human life, and of flesh and blood. Therefore, it seems worthwhile, and perhaps necessary, within a journal of theological reflection which has as its focus the JPIC process, to include a testimony to JPIC as it is lived out at the grassroots level. We know that women bear a disproportionate impact of the effects of poverty and unjust economic systems. Women too experience a disproportionate impact of the effects of racism. As bearers of life into the world, and as the primary nurturers of future generations, women claim a special place in relation to the environment. It is appropriate, therefore, that Cecilia Asogwa inserts into these JPIC reflections a personal account of a community of rural women in Africa who begin to work together in an economic self-help group, and in so doing discover themselves involved as active participants and leaders in their community. For these women, JPIC has meant personal and community empowerment which they have experienced as part of the healing of creation.     

The Perception of Ideal Best Friends by Chinese Adolescents

This study examines the characteristics of ideal best friends endorsed by Chinese adolescents. A comprehensive measure of person perception was used in order to assess those dimensions of personality where gender, similarity, and complementarity might be related to the rating of ideal best friends. Results indicated that ideal female best friends were rated higher on the communal dimension of Helpfulness; ideal male best friends were rated higher on the agentic dimensions of Extroversion, Assertiveness, and Application. Similarity effects were found for Openness to Experience, Extroversion, and Emotional Stability; complementarity effects for Assertiveness. These results were explained in terms of Chinese gender stereotypes and the requirements for harmonious dyadic interaction.     

Social support and psychosocial competence: Explaining the adaptation to college of ethnically diverse students

Examined relationships among social support, psychosocial competence, and adaptation to college in a sample of 357 African American, Asian American, Latino, and white college students. Social support and active coping were significant predictors of adaptation to college, whereas locus of control was not. However, there was an interaction between ethnicity and locus of control indicating that although internal African American, Latino, and white students had higher adaptation-to-college scores than external students, the opposite was true for Asian Americans. The relationships among social support, internality, and active coping were also explored. Satisfaction with social support and internality were positively related to active coping, but locus of control and social support were unrelated. Active coping and internality were significantly related to each other for all groups except for African Americans. Although most relationships were the same across groups, these findings call attention to the role of ethnicity as a moderator of college adjustment processes.     

Children’s acquisition of language: General linguistic competence or dimensions of style?

Previous studies have described children’s acquisition of language as reflecting either a referential or an expressive style. A multivariate approach, characterizing “referentiality” and “expressivity” as partially dissociable dimensions, is advantageous because it allows children to vary along one dimension as they vary along another, allowing children to have high or low degrees of both characteristics simultaneously. The present study applies multivariate techniques to an “exploratory” sample of 87 children, all of whom were 20 months old, and by subsequently validating the exploratory phase with 56 of the original children seen one month later. Using parental reports to assess children’s multiword productions, exploratory factor analyses revealed two correlated dimensions of language style which indeed reflected referential and expressive characteristics. Confirmatory factor analyses “confirmed” these factors in the test sample. This two-dimensional model of language acquisition was superior to a unidimensional, general linguistic competence model. There is also strong short-term stability for both dimensions across the one-month period.     

Assessment of Major Life Events for Hong Kong Adolescents: The Chinese Adolescent Life Event Scale

Previous Chinese research on adolescent life stress adopted life event scales that were directly translated from Western measures. To address the methodological and cultural issues overlooked by the import approach, the present research aimed at constructing a life event scale for Hong Kong adolescents. Study 1 was conducted to congregate items for the Chinese Adolescent Life Event Scale (CALES). The CALES contains 44 items derived from 618 Hong Kong adolescents. Study 2 revealed adequate test–retest reliability and criterion-related validity for the CALES. Moreover, the CALES yielded stronger relationships with depression than did the translated life event measures. Results suggest that the CALES is appropriate for assessing life events for Hong Kong adolescents. Both unique features of the CALES and life events found only in the translated measures are examined. Implications for Chinese research on life stress are discussed.     

A Latent Profile Analysis of Internet use and Its Association with Psychological Well-Being Outcomes among Hong Kong Chinese Early Adolescents

Nowadays, the Internet has penetrated into every aspect of our daily life. The aims of this study were (a) to examine the patterns of Internet use among Hong Kong early adolescents and (b) to explore whether such patterns differed in terms of the psychological well-being (happiness, loneliness, depression and hopelessness), sensation seeking and perceived social support. A total of 1401 Chinese adolescents participated in the study. Results from the latent profile analysis suggested that there were four latent profiles, and different patterns of the Internet use were associated with the psychological well-being, perceived social support and sensation seeking. The present study sheds light on the importance of considering the nature of online activity and the relationship between Internet use and psychosocial well-being. Implications of the study are discussed.
