The effects of alphabetic-reading competence on language representation in bilingual Chinese subjects

Summary The metaphonological abilities of two groups of bilingual Chinese adults residing in the Netherlands were examined. All subjects were able to read Chinese logograms, but those in the alphabetic group had, unlike those in the non-alphabetic group, also acquired some competence in reading Dutch. In Experiment 1, strong, significant differences between the two groups were obtained in the task of deleting the initial consonant of a Dutch spoken pseudo-word and also in a task consisting of segmenting a sentence into progressively smaller fragments, but there was no difference in a rhyme-nonrhyme classification task with pairs of Dutch words. In the latter task, the subjects in the two groups performed at a near-ceiling level. In Experiment 2, a significant difference was obtained again for the consonant-deletion task and no difference with an initial syllabic-vowel-deletion task, but the non-alphabetic subjects performed at a significantly lower level than the alphabetic subjects in the rhyme-judgement task. Taken together, these results are consistent with the earlier evidence that learning a non-alphabetic orthography does not promote awareness of the segmental structure of utterances. On the other hand, they confirm, for a population of Chinese readers, the conclusion drawn earlier from work with illiterate subjects that explicit instruction is more critical for the development of segmental representations of language than of representations of higher levels such as those of rhymes and syllables.     

IN-HOME GENERALIZATION OF SOCIAL INTERACTIONS IN FAMILIES OF ADOLESCENTS WITH BEHAVIOR PROBLEMS

The effects of a three-phase family communication program were evaluated. In the skill-teaching phase, family members were taught reciprocal social communication skills in a clinic setting. During the skill-review phase, each family member practiced the skills in their homes with the teacher. During the home-based family conference phase, each family was taught to use a structured format to resolve current family issues using their newly acquired skills. In-home parent-youth interactions were observed during a series of 1-hr sessions that involved directed and nondirected situations. Evaluation included a multiple baseline design across skills during the skill-teaching phase and a multiple baseline design across families for the family conference phase. Although the procedures of the skill-teaching phase resulted in parent-adolescent dyads learning to use the skills in the teaching setting, competent use of the skills in the home was not observed until the family conference phase was implemented. These results suggest the importance of home-based intervention if changes are to be obtained at home.     

Consolidation of Memory for Odor–Reward Association: β-Adrenergic Receptor Involvement in the Late Phase

Experimentally naive rats can learn rapidly to discriminate among three odors to obtain food reinforcement. After three massed trials, they show almost errorless performance. This task has proved to be useful in studying time-dependent postacquisition intracellular processes necessary for long-term memory. The present experiments evaluated the temporal dynamics of the role of β-noradrenergic receptors in long-term consolidation. Rats were implanted with intracerebroventricular cannulae and trained in a single session to find reinforcement in a hole in a sponge impregnated with a particular odor. Injections of the β-receptor antagonist timolol were made at 5 min, 1, 2, or 5 hr after training. Memory and relearning ability were evaluated 48 hr later. Rats treated with timolol 2 hr after training showed a memory deficit at the retention test, but were able to relearn the task normally. Injections at the earlier or later time points were ineffective. The results reinforce previous observations with systemic injections that β-noradrenergic receptors are involved in the late phase of memory consolidation and suggest a critical time window during which they are necessary. The time window is compatible with the current view that long-term memory depends on late involvement of the cAMP cascade leading to new protein synthesis necessary for synaptic reorganization.     

The History of Family Therapy in South Africa

The history of family therapy in South Africa is presented from 1960 up to the present. The early days leading to the establishment of the South African Association of Marital and Family Therapy, national conferences, publications, national and international links are discussed.     

Adolescent Female Identify Development

The purpose of this study was to (a) add to the current literature on female identity development and (b) determine whether a gender specific pattern of identity formation is evident in females during their early and middle adolescent years. The Measures of Psychosocial Development (MPD) was administered by graduate students to 317 males and 332 females in sixth, eighth, tenth, and twelfth grades from schools in a small and a mid-sized mid-western city. The schools were selected because they were representative of the racial/ethnic status of the cities (African American, 12%, Asian American, 4%, European, 63%, Latino, 10%, and Native American, 6%; 5% did not state their ethnicity). The results of the two by four analyses of variance (gender by grade) indicated that females blend interpersonal and intrapersonal identity development, whereas males appear to develop only intrapersonal identity. Limitations and recommendations for future research are also included.
