Predictors of preschool language environments and their relations to children's vocabulary

Despite support for the importance of early language environments, little is known about the naturally occurring experiences children have in preschool settings. The current study sample included 91 children (M_age = 4.72 years; 56% male; 67% White) from 23 preschool classrooms and nearly 1500 h of language environment data from three waves throughout the preschool year. Of the sociodemographic characteristics, family income is most closely related to children's preschool language environments. A standard deviation increase in family income was related to children hearing approximately one million more adult words in their preschool classroom. However, conversational turns were the more robust predictor of vocabulary skills with effect sizes around 0.20, depending on model specification. Theoretical and policy implications of these findings are discussed.     

‘When my mummy and daddy aren't looking at me when I do my maths she helps me’; Children can be taught to create imaginary companions: An exploratory study

Spontaneous imaginary companion (SIC) creation in childhood is a typical imaginative play behaviour associated with advanced sociocognitive skills; however, the direction of causality has not been established. To investigate this experimentally, researchers must determine whether children can create, on request, qualitatively equivalent imaginary companions (ICs) to those created spontaneously. We examined whether children could create ICs, and how these compared to SICs. Nine elementary school children were encouraged to create ICs in a 3-month intervention. Accounts of elicited ICs were compared with an age-matched sample of interviewees with SICs. Seven children maintained ICs for 6 months post intervention. Template analysis of IC interviews found four themes: Realistic Play, Multifaceted IC Mind, Utility of the IC, and Elicited IC Across Time. Analysis suggests elicited and SICs were similar in nature and utility, although intervention ICs tended to have animal rather than human appearances. Findings support the argument that children can be encouraged to create ICs similar to SICs.     

PROVIDING A MORE APPROPRIATE EDUCATION FOR SEVERELY HANDICAPPED PERSONS: INCREASING AND VALIDATING FUNCTIONAL CLASSROOM TASKS

We evaluated a teacher training and supervision program for increasing the involvement of severely handicapped adolescents and adults in functional educational tasks. The program, consisting of a brief in-service followed by supervisory prompts and feedback, was accompanied by large increases in functional tasks in three classrooms. In addition, generalized increases occurred during nontargeted times in the classroom and the changes during both the targeted and nontargeted times were maintained over a 44–45 week period. In two subsequent experiments, surveys provided social validation for the criteria for functional versus nonfunctional tasks in that: (a) relevant individuals reliably categorized functional tasks as representing typical living, work, social, and leisure situations and (b) experienced clinicians consistently rated tasks previously categorized as functional as being more useful for severely handicapped persons than tasks categorized as nonfunctional. Results are discussed in terms of the relationship of functional classroom tasks in the overall provision of appropriate educational services for severely handicapped students.     

Effects of opiate antagonists on spatial memory in young and aged rats

The effects of post-training opiate antagonist administration on spatial memory were assessed in young and aged male Long Evans rats. In Experiment I rats were trained to visit each arm of an eight-arm radial maze once in a session to obtain a food reward placed at the end of each arm. During training aged rats required significantly more trials to achieve criterion performance when compared to young mature rats. However, administration of the opiate antagonist naloxone (2.0 mg/kg) immediately after each training trial did not significantly alter the rate of achieving accurate performance in either age group. In Experiment II young and aged rats that were previously trained to a comparable criterion on the radial maze were tested on the same maze apparatus in novel spatial environments. When animals were exposed to novel spatial information, the effects of post-trial opiate antagonists were examined using a within-subjects counter-balanced design. In Experiment IIa naloxone (2 mg/kg) enhanced the performance of both young and aged rats. In Experiment IIB naltrexone (1.0 mg/kg) was found to have a comparable effect of enhancing the performance of both age groups. In addition, in Experiment IIb a significant age-related deficit was found in rats tested in novel spatial environments. These results indicate that opiate antagonists are capable of improving memory for new spatial information in both young and aged rats on a task that is sensitive to behavioral deficits during normal aging.     

Spirituality,health care,and bioethics

This article explores the relationship of spirituality to health care and bioethics in terms of the need and efforts of people to make sense of their lives in the face of illness, injury, or impending death. Moving beyond earlier associations with specific religious traditions, spirituality has come to designate the way in which people can integrate their experiences with their sense of ultimate meaning and related values. The holistic model of health care also affirms that one should not simply treat a body in pain, but respond to the suffering of the whole person within his or her full life. A narrative emphasis in ethics also maintains that ethical decisions occur within the framework of interacting life-stories, each of which embodies a certain core vision and set of values. In each instance it is the life stories of people, their lived narratives, that provide a common thread. The telling of these stories and the discernment of the lived spirituality they contain may assist persons in the process of achieving understanding, making decisions, and finding purpose in the experience of illness, injury, or disability.Maureen Muldoon, Ph.D., is Associate Professor in the Department of Religious Studies, University of Windsor, Windsor, Ontario, and Norman King, Ph.D., is Professor in the same department.     

FUNCTIONAL ANALYSIS AND INTERVENTION FOR BREATH HOLDING

We conducted a functional analysis of breath-holding episodes in a 7-year-old girl with severe mental retardation and Cornelia-de-Lange syndrome. The results showed that breath holding served an operant function, primarily to gain access to attention. The intervention, consisting of extinction, scheduled attention, and use of a picture card communication system, resulted in decreased breath holding.     

No regrets: Custodial mothers' accounts of the difficulties and benefits of divorce

This study examines the accounts of 80 divorced single mothers in order to consider various emotional processes involved in the mothers' postdivorce family reorganization. A qualitative analysis was conducted on written responses to an open-ended question. Concerns tended to center around how the divorce had affected the children as well as various difficulties associated with single parenting. Loss and guilt on the part of many mothers was tempered by positive attributions about how divorce actually gave way to greater personal happiness, better parent-child relationships, and more rewarding lives. Focusing on the benefits of divorce appeared to be an important means of coping with many of the problems inherent in single parenting. Implications for treatment are discussed from an ecological perspective which emphasizes the therapist's role in helping mothers to create contexts of support.This research was funded in part by grant number 9103 from the Women's Research Institute, Virginia Polytechnic Institute and State University.
