Cognitive structures in comprehension and memory of narrative discourse

The effects of structure and content variables on memory and comprehension of prose passages were studied in two experiments. The experimental passages exemplify a class of simple narrative stories that is described by a generative grammar of plot structures. A comprehension model is proposed that assumes a hierarchical organizational framework of stories in memory, determined by the grammar, representing the abstract structural components of the plot. The quality and characteristics of subjects' memory for stories were tested on a variety of experimental tasks in which story organization was manipulated. Comprehensibility and recall were found to be a function of the amount of inherent plot structure in the story, independent of passage content. Recall probability of individual facts from passages depended on the structural centrality of the facts: Subjects tended to recall facts corresponding to high-level organizational story elements rather than lower-level details. In addition, story summarizations from memory tended to emphasize general structural characteristics rather than specific content. For successively presented stories, both structure and content manipulations influenced recall. Furthermore, repeating story structure across two passages produced facilitation in recall of the second passage, while repeating story content produced proactive interference. The implications for a model of memory for narrative discourse are discussed.     

The motive to avoid success: A further examination

Horner's (1968) “fear of success” study was replicated and expanded. One hundred seventy-seven high school (HS) and college students wrote stories in response to the following cues: “After first-term finals, John (Anne) finds himself (herself) at the top of his (her) medical-school class.” Results indicated similarity of response of HS men, HS women, and college men, all of whom expressed more fear of success imagery in response to the Anne cue than to the John cue. College women did not conform to this pattern.     

The early history of behavior modification of stuttering: A view from the trenches

The attitudes of 644 employers toward stuttering were studied through the use of a questionnaire which required the respondents to indicate their strenght-of- agreement to seven attitudinal statements concerning stuttering. While rejecting the suggestion that stuttering interferes with job performance, the employers agreed that stuttering decreases employability and interferes with promotion possibilities. It was concluded that although stuttering may not typically interfere with job performance, it is a significant vocationally handicapping problem.     

Learning from negative outcomes in stuttering therapy: II. An epiphany of failures

Proceeding on the premise that learning advances on the feet of failure, a litany of therapeutic failures with stutterers across 3 decades is recounted. The basis for these failures included the assumptions that stuttering is a neurotic symptom; that “lucky fluency” can be maintained permanently; that a fluent drone is preferable to stuttering; that controlled fluency, once established, can be maintained permanently; that a proper task for clinicians is to motivate clients to achieve and preserve fluency; that the clinician has the responsibility for marching clients through their therapeutic paces; and that stuttering is punishing to the stutterer, so it is not preserved by reinforcement. Unfortunately, more has probably been learned about what does not work than what does.     

Language loss in bilingual Chicano children

The results of two studies on language loss in bilingual Chicano children are reported. In Study I, focusing on normal language acquisition in balanced bilinguals, 41 children in kindergarten through fourth grade were administered the Bilingual Language Acquisition Scale (BLAS), an instrument testing comprehension and production of the following features: number, gender, word order, relatives, conditionals, and Spanish subjunctive and its English equivalents. Most development occurred between kindergarten and the upper grades in the English Comprehension and Production subscales. In the production of Spanish, significant differences appeared between kindergarten and the upper grades to grade three. Unexpectedly, in the fourth grade, performance dropped sharply, with children performing almost at the kindergarten level. There were no significant differences by grade in Spanish comprehension. Most significant differences among grades were produced in the more complex categories (conditionals, Spanish subjunctive/English equivalents, and relatives) in the production subscales in English and Spanish. By fourth grade, in Spanish (and sometimes by third grade), children were performing with significantly lower accuracy than the younger children, particularly in the more complex structures (subjunctive and conditionals, for example). In Study II, 32 of the original subjects were retested two years later using the same instruments and procedures. While performance in English continued to improve for the sample as a whole, performance in Spanish production deteriorated to a significant degree. In Spanish, significant differences in performance between the two administrations were found, both for the scale as a whole and for the following categories: past tense, relatives, and the subjunctive. The influence of personal history and language use patterns was tested. The most severe incidence of loss occurred among children who tended to use both English and Spanish with the same speaker.     

Caregiver behavior in center and family day care

In an effort to examine relationships between variations within day care settings and adult caregiving behaviors the social experiences of 40 toddlers and their caregivers in family and center care were systematically observed. Caregivers were interviewed and conditions of caregiving recorded. Caregivers in both settings with fewer children in their care, who worked shorter hours, with less housework responsibilities engaged in more facilitative social stimulation, expressed more positive affect, were more responsive, and less restrictive and negative. Family day care caregivers who worked in spaces specifically designed to be safe and appropriate for children were less restrictive of toddler activity. Adult-child ratio and caregiver training appeared to be the best indicators of quality care in center day care, while a safe and appropriate caregiving environment and small groups appeared as quality indicators in family day care.     

Reaction time, intelligence, and attention

The roles of attention in reaction time and in the relationships among reaction time, intelligence, and achievement were analyzed. The subjects were 105 seventh-grade children. The results were generally consistent with most studies involving the Hick paradigm: both mean reaction time and the standard deviation of reaction time correlated with the intelligence and achievement measures used. Reaction time measures were correlated with attention and perceptual speed as well as with general intelligence, or g. Implications of these results for current theories linking reaction time and intelligence are discussed.     

Divided attention: Evidence for coactivation with redundant signals

Many models of divided attention assume that signals presented on different channels produce separate activations, any one of which can initiate a response. According to these models, detection responses are especially fast when signals are presented on two channels at the same time because the system can detect a signal in either of two ways. Such models predict a testable relation among reaction time distributions for conditions in which a single signal is presented as compared with a condition in which two signals are presented, and this prediction is tested in two tasks. A bimodal detection task required a simple speeded response to either a visual or an auditory signal. A letter search task required a choice response depending on whether or not a two-letter display included the signal letter “A.” Data from both tasks are inconsistent with the prediction. When two signals are presented, responses are faster than separate-activation models can explain. The results favor “coactivation” models, in which signals presented on different channels contribute to a common pool of activation that initiates a response.     

Cerebral organization in adult second language acquisition: Is the right hemisphere more involved?

A Spanish-English dichotic listening study was designed to test the hypothesis that the right hemisphere might be more involved during the initial stages of informal, adult second language acquisition. No evidence was found in support of the hypothesis. Results are discussed within the general theoretical framework of the right hemisphere's role in second language performance and bilingualism.
