Acquisition and forgetting in monkeys' memory of informational object-reward associations

The first experiment showed the monkeys could recall whether an object had been rewarded with peanuts or with sultanas, two equally preferred foods. The second investigated the effect of rewarded trials with an object on monkeys' ability to recall a nonrewarded trial with the same object. The third demonstrated that monkeys could use the memory of reward to predict nonreward and the memory of nonreward to predict reward, in a Win-Shift Lose-Stay paradigm. The fourth found differences between Win-Shift Lose-Stay and Win-Stay Lose-Shift in the rate at which associations between objects and reward events were forgotten. These results are discussed in relation to D. L. Medin's (In A. M. Schrier, Ed., Behavioral primatology, Hillsdale, N.J.: Erlbaum, 1977, Vol. I, pp. 33–69) distinction between informational and hedonic effects of reward in monkeys. It is argued that the association between an object and a reward event is represented in memory by many independent traces, different traces recording the object's association with different attributes of the reward event.     

The effect of syntactic encoding on sentence comprehension in aphasia.

This study compared two levels of syntactic encoding with respect to their effect on aphasics' auditory comprehension. The same informational content was presented either as an embedded sentence or as two contiguous simplé propositions. A similar contrast was utilized to compare sentences containing relational terms of time, comparison, instrumentality, as well as sentences involving conjunction reduction, with parallel messages expressed in expanded, simplified form. A picture-verification paradigm was used. Comprehension was significantly enhanced only in the case of embedded sentences, with a tendency for Broca's aphasics to show the maximum effects.     

论孙中山民主主义的服务道德

孙中山在其三民主义的政治基础上,形成了他的民主主义的伦理思想,突出特色是他所倡导的“服务道德”。其要点是,以民主平等取代等级特权制度,这是服务道德的政治前提;实行人道主义、维护人的尊严,这是服务道德的基本要求;铲除皇帝思想、树立公仆观念,这是实践服务道德的基本途径。孙中山的伦理思想有明显的历史局限性,但是,他的“服务道德”思想仍然是值得借鉴的。     

A Narrative Approach to Child and Family Therapy in Africa*

Professional family therapy in Africa is heavily influenced by theories and principles of Western family practice. Its practice structure and philosophies are however grounded on African family values and the principles and orientations of traditional African psychology. This paper presents a clinical report that illustrates adaptations we make to incorporate compatible aspects of narrative family practice in African and Western cultures. A summary of African family values and child psychology intended as a background perspective is provided. The paper is significant against the background of the current need for forging multiculturally relevant healing methods that fit well with the globalized nature of the contemporary world. Augustine Nwoye, PhD, is Associate Professor and Chairman, Department of Psychology, Kenyatta University, Nairobi, Kenya (amnwoye@avu.org). Professor. Nwoye has developed an African paradigm for mental health and, in particular, for family and couple therapy. He also has experience in dealing with stress and multiple losses, especially surrounding HIV/AIDS within an African context. *An earlier version of the paper was presented to the members of staff and students of the Faculty of Education, University of Cambridge, England, UK, and the initial version was presented to the members of the Family Therapy Program of the Faculty of Medicine of the University of Calgary, Calgary, Canada. I wish to thank Dr. Colleen McLaughlin (University of Cambridge) and Professor Karl Tomm (University of Calgary) for their invitation, assistance, time, attention, and suggestions.     

Children's detection and awareness of textual anomaly

Children of 8 and 11 years were assessed in two experiments for their sensitivity to textual anomaly. In Experiment 1, subjects read stories containing two target lines, one appropriate and the other anomalous in relation to previously given information. Both age groups read the anomalous line more slowly than the appropriate line, but in a subsequent test of comprehension monitoring, the older group was more likely than the younger group to pick out the anomalous line as not fitting in with the rest of the story. Experiment 2 produced similar results: both 8- and 11-year-old children read an anomalous line more slowly, but 11-year-olds were more likely than 8-year-olds to cite the anomalous line or part of it when questioned about the possible presence of a line that did not fit in with the rest of the story. The results indicate that an age change in comprehension monitoring as indexed by citation or selection of a textual anomaly need not be contingent upon a parallel age change in constructive processing as indexed by modulation of reading rate.     

Effects of tobacco use on non-adherence to antiretroviral therapy among HIV-positive patients in South Africa

This study aimed to estimate the relationship between tobacco use and non-adherence to antiretroviral therapy (ART) in a South African sample. Participants were 1 963 HIV patients who attended a primary care clinic in Pretoria (female = 68.5%; black African = 99.5%; median age = 37.0 years; tobacco users only = 8.6%, problem drinkers only = 14.9%, and tobacco users and problem drinkers = 10.5%). In adjusted logistic regression analysis, tobacco use only was not significantly associated with non-adherence to ART. Alcohol use only (OR: 1.72; CI: 1.26, 2.36) and tobacco use and problem drinking (OR: 2.31; CI: 1.60, 3.33) were highly associated with non-adherence to ART.     

“We're Fighting Two Different Battles Here”: An Exploration of African American Women's Definitions of Self at Predominately White Schools

Using Black feminist thought and the sociocultural model of the self, this paper explores the relationship between race and gender in the self-definitions of African American women attending predominately white colleges and universities. The African American women who participated in the study, suggest that knowledge generated about the self pushes us beyond the categorical thinking that limits our ability to understand the complexity of the self. Data from 13 interviews conducted at two predominately white schools is presented and analyzed. Using this data, I present a way of thinking about the identity of African American women that demonstrates the complexity of defining self within the narrow confines of race and gender.
