Categorization of Ambiguous Sentences as a Function of a Changing Prosodic Parameter: A Dynamical Approach

The present study investigates the dynamics of changes in interpretation of ambiguous sentences. The sentences used had alternative interpretations with different surface structures (bracketing). Continua were created by systematic manipulation of prosodic cues (relative foot duration), resulting in stimulus sentences that spanned the range between the two interpretations. Continua were presented to subjects who were requested to indicate as quickly as possible which meaning they perceived. The pattern of responses and response times revealed the presence of hysteresis. That is, when the values of prosodic parameters are congruent with both interpretations, the individual's recent history decides which meaning will be perceived. Thus, we can treat this categorization process as a transition from an initially stable meaning that loses stability with variations in prosody (our control parameter). The same underlying dynamics have been observed in studies of perception of syllables and aspects of visual perception. Apart from demonstrating the same characteristics of pattern formation at various levels of cognition, the study points to the usefulness of the dynamical approach in the investigation of language understanding.     

Recall of semantic clusters in primary memory

An experiment is reported which investigated the use of semantic relatedness as a retrieval cue in the primary memory component in a free recall task. Six-word semantically related clusters were placed in the middle and end positions of free recall lists. Retention was measured immediately after the list presentation and after a filled retention interval of 15 sec. Pure primary memory functions were calculated. The results indicated that semantic cues are useful in retrieval from secondary memory but played no part in recall from primary memory.     

Gender-specific common nouns: Sex differences in self-use

Males and females completed questionnaires on self-esteem and on their use, applied to themselves, of (a) girl/boy, (b) gal/guy, (c) lady/gentleman, and (d) woman/man in 10 situations. Terms chosen did not vary with self-esteem or with psychiatric vs nonpsychiatric status. Older subjects preferred lady/gentleman and woman/man. Females seldom chose gal, and used it less often than males used guy. Both sexes chose girl/boy most in negative situations. Females used girl more than males used boy in self-praise situations. Females preferred both sexes to think of them as ladies. Males preferred females to think of them as gentlemen and thought that term most complimentary, but preferred males to think of them as men. These results are discussed in terms of societal sex roles.The authors wish to thank Gary Leonardson, Ph.D., and Nancy Henley, Ph.D., for their aid in completing this study.     

Repetition of cues in children's oddity learning and transfer

The hypothesis that repetition of specific cues interferes with oddity learning was directly tested by comparing two groups of preschool (3 to 5 years of age) children, one with repeated cues and the other with new cues on every trial. Repetition of cues retarded oddity learning confirming previous speculation based on error analyses. Performance on postsolution transfer trials with repeated cues was not affected by conditions of acquisition. Significant age effects were found in oddity acquisition, while there was only weak evidence for agerelated performance differences on transfer trials. Transfer performance on trials with repetition of cues was not related to whether or not the children were informed of such repetition. The results were related to theories of oddity acquisition and transfer.     

Use of nature in a multi-family therapy for Chinese families of adolescents with attention deficit hyperactivity disorder: A photo-elicitation study

This article reports the therapeutic resources in the natural outdoors that were conducive to the therapeutic process in a multi-family therapy (MFT) for enhancing the self-efficacy and collective family efficacy of Chinese families of adolescents with attention deficit hyperactivity disorder (ADHD) in Hong Kong. Photo-elicited interviews with adolescents with ADHD and parent focus groups were employed to explore the participatory experiences of the families. A total of thirteen Chinese families of adolescents (aged 11–15 years) with ADHD participated in this study (fourteen adolescents with ADHD, eight fathers and ten mothers). The present study explored the potential therapeutic resources in the natural outdoors, namely a change in the group environment, spaciousness and darkness. The use of the natural outdoors in MFT proved to be a strategy useful for creating a naturalistic group setting within which family participants can more easily enact changes.     

Contextual influences on narrative discourse in normal young adults

In an effort to provide some expectation regarding the influences of task and rehearsal, the narrative ability of 20 normal young adults was examined under the conditions of story retelling and story generation. Each task was repeated after a 1-week interval in order to investigate a possible practice effect. Sentence production, intersentential cohesion, and story grammar organization were analyzed. Results indicated that the subjects' performance varied as a function of task presentation as well as the measure used to describe narrative production. The only across-trials difference noted was an increase in cohesive adequacy from trial 1 to trial 2 for one of the story generation tasks. It may be concluded that (a) context does influence the manner and competence of narrative presentation, and (b) that rehearsal of a complex narrative improves narrative coherence.     

Does the use of dolls facilitate children's memory of visits to the doctor?

Age differences in children's recall of salient experiences have frequently been documented, but these findings have routinely been based on studies in which verbal interviews have been employed. Because verbal interview protocols may underestimate the memory of young children, the purpose of this research was to compare the effectiveness of such an interview with two alternative protocols that involved the use of a doll. Using these contrasting protocols, 3-and 5-year-old children were asked to remember the details of a routine physical examination. Neither doll protocol facilitated 3-year-olds' recall of the features of the check-up. In contrast, 5-year-olds who were asked to demonstrate with a doll what happened in their examination showed enhanced recall. The inclusion of a doll had no effect on older or younger children's provision of elaborative detail about their visits to the doctor. Various measures of individual differences (e. g. temperament, language skill) predicted some aspects of the children's recall and elaboration. The findings are discussed in terms of the cognitive skills necessary for effective use of dolls in the assessment process, and are related to problems associated with interviewing young children who are involved in legal proceedings.
