Storage and processing constraints on integrating story information in children and adults 总被引:1,自引:0,他引:1
B P Ackerman 《Journal of experimental child psychology》1984,38(1):64-92
In two experiments, this study examined the effects of integration complexity on the ability of child and adult listeners to integrate information from different sentences in a story. First and third graders and college adults were read stories containing incongruent event information and succeeding resolution information that explained the incongruency, and asked questions that probed incongruency recognition and resolution. Information storage complexity was manipulated by separating the event and resolution information and foregrounding or backgrounding the focal story characters. Processing complexity was manipulated by varying the inferential complexity of relating the resolution to the incongruent information, and the coreferential cues linking the event and resolution information. The results showed that increases in complexity adversely affected resolution integration, and more for the children than for the adults. The children's integration performance, in particular, was affected by theme discontinuity and coreferential complexity. 相似文献

In four experiments, this study examined some reasons why second and fourth grade children use cues relatively ineffectively to retrieve episodic information in memory. Retrieval success was conceptualized as using a cue to describe episodic information in memory. The experiments manipulated factors hypothesized to affect the discriminability and constructability of compatible encodings of context cue information at retrieval. In general, the effects were accomplished by varying the specificity of cue-target information at acquisition, and similar or different samplings of cue information alone at retrieval by means of orienting questions. Experiment 1 varied the encoding of item specific or categorical information. Experiment 2 varied the encoding of supercategorical or subcategorical information. Experiment 3 used two acquisition trials, crossing Categorical × Item Specific encoding and repeating identical encoding experiences. Experiment 4 varied Separate and Interactive Imagery encoding instructions. The results showed that problems of both discriminability and constructability contribute to developmental differences in the use of retrieval cues. 相似文献

This study was designed to investigate the differences between stutterers and normal speakers in phonatory and articulatory timing during the initiation of fluent utterances of monosyllabic words. Electromyographic recordings of four articulatory muscles and recordings of glottal vibrations were made of repetitive utterances of a series of monosyllabic words by 15 stutterers and 17 nonstutterers. These data were analyzed in terms of average interval times between voice onset and onset of EMG activity and between onset of EMG activity in each articulator and in terms of the intrasubject variability of these durational measures. Results showed that there were no significant differences between stutterers and nonstutterers in average interval times and that stutterers, in general, were significantly more variable in their speech onset timing. Findings are discussed in terms of recent hypotheses concerning the role of timing disturbances as the main source of speech disruption in stutterers. 相似文献

This investigation was undertaken to explore the possible causes and consequences of the finding that attention- and learning-disordered children with sensitive (weak) nervous systems were titrated at higher dosages of methylphenidate than those with strong nervous systems. Pretreatment parent and teacher ratings of hyperkineticassociated behavior were no different for children typed as having strong or sensitive nervous systems or for those subsequently prescribed higher or lower dosages by a child psychiatrist “blind” to their type as well as condition (drug or placebo). However, those titrated at lower dosages, regardless of whether strong or sensitive, were rated as more improved than those given higher dosages. Pretreatment reaction time (RT) data suggested that sensitive types prescribed low dosages had less of a problem sustaining attention, and placebo RT data suggested that strong types titrated at low dosages had more of a problem sustaining attention. A contrast of placebo and drug RTs showed that strong types titrated at lower dosages improved more than strong types given higher dosages, whereas sensitive types given higher dosages improved more than sensitive types given lower dosages. The latter finding is thought to add support to the theory of Gray (1964), who suggested that, paradoxically, the weak nervous system needs a more intense stimulus than the strong to reach the concentration threshold. 相似文献

In a visual memory task, two degrees of stimulus detail were compared to test Reese's hypothesis that stimulus detail would facilitate retention of paired associates for young children. Stimuli were presented in an elaborated or nonelaborated fashion so that the effect of detail on retention of both types of materials could be investigated. Four and 5 year-old children were included to assess a reported developmental trend that elaboration facilitates retention for older children but fails to do so for younger children. Both age groups performed equally well, and detail had no effect. Elaboration aided retention significantly. A second study, in which difficulty of the task was increased, yielded equivalent results. The constraints on performance by recall and recognition tasks were discussed. 相似文献

The effect of sex role socialization practices on the achievement motivation (Nach) of black preschool children of differing social-class levels was examined. A factor analysis of the Katz Sex Role Socialization Scale revealed several factors. These varied in their effect on two types of achievement motivation. In general, the hypothesis that nontraditional sex role training leads to higher achievement motivation for girls, and that traditional sex role training leads to higher achievement motivation for boys, received support. The importance of treating sex role socialization as multidimensional was stressed.This study is part of a doctoral dissertation by the senior author. 相似文献

Young children (ages 2 to 5) have proved to be difficult subjects for obtaining valid reports of their ratings of olfactory stimuli. Thirty-six preschoolers were tested on benzaldehyde (a pleasant odor) and on dimethyl disulfide (an unpleasant odor) using a smiling or frowning face as a response format. The results showed the ability of young children to discriminate between pleasant and unpleasant odors. 相似文献

Interactions of stimulus consistency and type of responding were examined during perceptual learning. Subjects performed hybrid memory-visual search tasks over extended consistent and varied mapping practice. Response conditions required subjects to respond to both the presence and absence of a target, only when a target was present or only when a target was not present. After training, the subjects were transferred to a different response condition. The results indicate that: (1) performance on search tasks with stimuli that are variably mapped show no qualitative changes attributable to manipulation of response format; (2) improvement due to consistent mapping (CM) practice is attenuated in the no-only response condition; (3) yes-only CM training attenuates the subjects ability to transfer to no-only responding; and (4) yes/no CM training leads to the greatest improvement and transfer when compared with other responding conditions. The practice and transfer data support and extend previous research investigating effects of response set in memory/visual search and help to delineate factors that facilitate or inhibit reduction of load effects in memory and visual search. 相似文献

The existence of Pastoral Theology as a discipline is problematic. The possibility of becoming a discipline is discussed as requiring a shift from a clinical/therapeutic to an ecclesial paradigm as its center. The shift would foster a valuing of the pastor as an interpreter of human existence, attention to the need for a pastoral hermeneutic, and an appreciation for particularity. The field needs to attend its intellectual tasks and to assess the debits/credits of its relations to secular disciplines. 相似文献
