Graphics in written directions: Appreciated by readers but not writers

This series of studies investigated the ability of literate adults to exploit communications options that are available to writers but have no counterpart in speech. Specifically it examined people's use of sketches when giving written directions to help a stranger cross town. When writing an informal letter to a friend most directions were given in prose paragraph style (Experiment 1). Almost no-one included a sketch, even if given a street map as an aid. Yet most subjects could draw adequate sketch maps (Experiment 2), and everyone said yes when asked whether they would include a sketch in a letter. So the previous choices were not constrained either by graphic skill or by judgements concerning the appropriateness of a sketch, When people were asked to 'design' the back page of a leaflet they still did not include a sketch (Experiment 3). Experiment 4 showed that any bias in the instructions was towards rather than against the use of sketches. The need to generate the sketch was removed in Experiment 5 where subjects composed the leaflet page from pre-formed sections that included alternative routes in both words and diagrams. Nearly all subjects now included a sketch in their directions. In case subjects previously, in haste, had not considered the possibility of including a sketch map, they were made aware of the drawing option by rating the usability of route information in a variety of communication styles immediately before writing their own directions (Experiment 6). People rated directions that included diagrams as significantly more usable, but still most subjects did not include a sketch in the directions they gave. So the communication styles that readers recognized as successful were not determining their choices as writers. It is suggested that, when giving written directions, inexperienced writers rely too heavily on how they would respond as speakers.     

Selective mutism in children: A structural family therapy approach to treatment

When children refuse to speak in some social settings, but can understand and speak in other settings, the diagnosis of selective mutism must be considered. A review of the literature describes the disorder, the various types of mutism, and related family dynamics. A family systems approach to treatment using structural family therapy is suggested. The case history presented illustrates one type of mutism as well as the family rules and hierarchy which appeared to be maintaining it. Structural and strategic family systems theory techniques that were used to move the family toward resolution of this problem are discussed.Diane Wolf Tatem, MA, MS, completed graduate work in marriage and family therapy at New Mexico State University, Las Cruces, NM.

MOTHERS' ALCOHOL CONSUMPTION DURING PREGNANCY:

Abstract— Fourteen-year-old adolescents' behavior on a spatial-visual reasoning task was associated with self-report of their mothers' alcohol consumption during pregnancy, IS years earlier The task was arranged so that it was possible to evaluate the examinees' tendency to respond rapidly and less accurately, or slowly and more accurately The greater the mother's reported drinking, the faster and less accurately the adolescent responded The decrement in visual-spatial reasoning related to alcohol appears to be linked to a tendency toward impulsive responding     

PREVENTION OF DEPRESSIVE SYMPTOMS IN SCHOOLCHILDREN:

Abstract— After teaching cognitive and social-problem-solving techniques designed to prevent depressive symptoms, we followed 69 fifth- and sixth-grade children at risk for depression for 2 years. We compared these children with 49 children in a matched no-treatment control group The prevention group re- ported fewer depressive symptoms through the 2-year follow-up, and moderate to severe symptoms were reduced by half. Surprisingly, the effects of the prevention program grew larger after the program was over. We suggest that psychological immunization against depression can occur by leaching cognitive and social skills to children as they enter puberty     

The modification of auditory hallucinations

The ABAB withdrawal design was used to document the effectiveness of a behavioral treatment package in reducing the duration of auditory hallucinations of a chronically mentally ill inpatient. Results revealed clear functional control of the treatment package over the occurrence of the subject's auditory hallucinations during a 2-hr time period.     

Case study: Examining the relationship between self-initiations of an individual with disabilities and directive behavior of staff persons in a residential setting

This case study examines the relationship between self-initiations of an adult woman with severe disabilities and the directive behavior of staff persons in a community residential setting. Hypotheses generated from functional assessment procedures indicated that (a) Susan's low self-initiations were very likely related to high directive behavior of staff persons, and (b) infrequent problem behaviors during the morning routine were maintained by escape from repeated staff demands. An intervention was implemented to enable Susan to increase self-initiation in choice and sequence of activities and simultaneously decrease staff directives. Results and discussion focus on the need for a contextual approach for addressing problematic situations and an affirmation of the effectiveness of the positive behavioral support technology for increasing adaptive behaviors in individuals with severe disabilities.
