Developing Data-Based Communications in Social Psychological Research: Adolescent Smoking Prevention1

The present paper deals with how pre-intervention data were gathered from a sample of junior high school students to whom a smoking prevention program was addressed and how these data were used in the creation of trigger films which were an important element in the prevention program. The coping techniques used by students who are successfully able to withstand social pressures to smoke were determined from pre-intervention group interview-role-playing sessions with samples of students from two schools representative of the intended target population of the smoking prevention program. These data were used in the production and editing of ten-minute, sound, color films which reflected simulations of the student responses in the interview-role-playing sessions. Assessment of the impact of these filmed social-inoculation coping strategies indicates that they appear to be a promising component of smoking deterrent programs for adolescents.     

Measuring the effects of demand characteristics on the Beck Depression Inventory responses of college students

To determine whether Beck Depression Inventory (BDI) responses could be influenced by an instructional set or by changing the item order, 198 college students were randomly assigned to one of four conditions: instructions designed to facilitate or inhibit responding, along with standard vs. reordered symptom questions. A 2×2 ANCOVA found a main effect only for the inhibitory message. The suppression of scores by the inhibitor instructional set suggests caution regarding possible demand characteristics when using the BDI with this population and should be further studied with clinically symptomatic samples.     

Behavior modification consultation in a Mexican-American school

Following consultation by two psychologists with an elementary school populated primarily by Mexican-American students, absenteeism was chosen as the first problem area to attempt to change. A between-groups experimental design was used to evaluate the effect of contigent rewards on the students' attendance. Analysis of the data showed no improvement in attendance. The results of the study were discussed in terms of (1) a more thorough behavior analysis of the absenteeism problem, (2) methodological restraints of a between-groups experimental design, (3) the need for consultants to be familiar with the community in which they work, and (4) relatedly, the success of the local school psychologist in implementing behavior modification programs.     

Temporal changes in visual and acoustic codes in a letter-matching task

The objective of the present experiment was to examine the nature of the coding process in a letter-matching task. Letter pairs that were either visually confusable or acoustically confusable or both visually and acoustically confusable were presented tachistoscopically with a variable interval between the first letter and the comparison letter. The dependent measure was RT for the “different” responses to the three types of confusable items which were each assessed at four interstimulus intervals ranging from 0 to 2 sec. The results indicate that a visual code appears to be emphasized for approximately 1 sec, after which an acoustic code seems to be dominant. There is also evidence which indicates that the acoustic code does not immediately replace the visual code and that both may coexist for a brief period of time.     

Assessment of a microcomputer-based version of the Austin maze

The Austin (or Milner) Maze consists of a 10 x 10 array of electrical contacts through which the subject must discover a hidden pathway by touching successive points in the matrix. Trials needed to reach 3 consecutive errorless performances, errors committed, and time taken to reach this criterion are commonly regarded as indicators of frontal lobe function. This study evaluated the equivalence of a computer-based version of this task. Thirty-two male computer science students completed both forms of the maze in counterbalanced order, separated by an interval of 4 weeks. In a 2-year follow-up, 25 remaining subjects completed the tasks in reverse order, again separated by a 4-week interval. Correlational data and analysis of variance supported the proposition that the computer-based version could act as a substitute for the more tediously administered traditional form. Although the sample characteristics may limit the generalizability of this conclusion, the application and development of the software by independent investigators may facilitate its clinical application and allow a more efficient resolution of relevant theoretical issues.
