Mothers' speech in three social classes

Functional and linguistic aspects of the speech of Dutch-speaking mothers from three social classes to their 2-year-old children were studied. Mothers' speech in Dutch showed the same characteristics of simplicity and redundancy found in other languages. In a free play situation, both academic and lower middle class mothers produced more expansions and used fewer imperatives, more substantive deixis, and fewer modal verbs than working-class mothers. These differences were not present while mothers were reading books with their children. In general, the mothers' speech was more complex in the book reading situation than during free play.     

MOTIVATING AUTISTIC CHILDREN THROUGH STIMULUS VARIATION

This study evaluated the differential effectiveness of two methods of presenting discrimination tasks when teaching autistic children. In a constant task condition, the common method of presenting a single task throughout a session was used. In a varied task condition, the same task was interspersed with a variety of other tasks from the children's clinic curricula. Results showed declining trends in correct responding during the constant task condition, with substantially improved and stable responding during the varied task condition. In addition, naive observers judged the children to be more enthusiastic, interested, happier, and better behaved during the varied task sessions. These results suggest that “boredom” may be a particularly important variable to control in the treatment of autistic children, and that particular care may be necessary when defining criteria for task acquisition. The results are discussed in relation to the literature on increased responsivity to stimulus novelty and variation.     

INTERTRIAL INTERVAL DURATION AND LEARNING IN AUTISTIC CHILDREN

This study investigated the influence of intertrial interval duration on the performance of autistic children during teaching situations. The children were taught under the same conditions existing in their regular programs, except that the length of time between trials was systematically manipulated. With both multiple baseline and repeated reversal designs, two lengths of intertrial interval were employed: short intervals with the S^D for any given trial presented approximately one second following the reinforcer for the previous trial versus long intervals with the S^D presented four or more seconds following the reinforcer for the previous trial. The results showed that: (1) the short intertrial intervals always produced higher levels of correct responding than the long intervals; and (2) there were improving trends in performance and rapid acquisition with the short intertrial intervals, in contrast to minimal or no change with the long intervals. The results are discussed in terms of utilizing information about child and task characteristics in terms of selecting optimal intervals. The data suggest that manipulations made between trials have a large influence on autistic children's learning.     

INCREASING THE INDEPENDENT RESPONDING OF AUTISTIC CHILDREN WITH UNPREDICTABLE SUPERVISION

We investigated the role of predictable versus unpredictable supervision on the independent task responding of three autistic children. In a predictable supervision condition, the therapist was present in the setting for a regular period of time and then was absent for the remainder of the session. In an unpredictable supervision condition, the therapist's presence was scheduled on a random, intermittent, and unpredictable basis throughout the session. The multiple baseline analysis showed that the unpredictable supervision produced much higher levels of on-task responding during the therapist's absence for all three children. Analysis of work completed during the therapist's absence also favored the unpredictable supervision condition. The results are discussed in relation to the literature on generalization and educational practice.     

Consumer Wisdom: A Theoretical Framework of Five Integrated Facets

We establish a parsimonious theoretical framework of consumer wisdom based on five mutually reinforcing psychological facets. Our research draws from wisdom literature and a set of 31 phenomenological interviews with informants who were identified through a multi‐stage nomination process. The five facets of consumer wisdom that emerged are Intentionality, Contemplation, Emotional Mastery, Openness, and Transcendence. Together, they comprise a data‐grounded, aspirational model of consumer wisdom—for researchers as well as consumers—to understand, maintain, and improve personal and collective well‐being. We discuss the implications of the framework and directions for future research.
