Managing data entry of a large-scale interview project with optical scanning hardware and software

A hardware and software system for the cost-effective preparation of interview data is described. Scantron optical scanning hardware and DataBlocks software were used to prepare ASCII data files from structured interviews and questionnaires. These data were then edited for analysis with SPSS-X Data Entry software. Three different processes for preparing interview data were compared. Time, personnel, hardware, and software costs were projected for each process, as well as comparative risks to the integrity of data. A scanning procedure saves time and money, and it reduces the risk of errors.     

The structure and function of social support networks in families with handicapped children

Three structural characteristics of social support networks (size, density, and boundary density) and two relationship characteristics (reciprocity and dimensionality) were assessed in a sample of 56 families with a child with spina bifida and 53 matched comparison families. The results indicate that social networks of families with handicapped children tended to be smaller than the networks of comparison families, particularly with regard to mothers' total and friendship networks. The networks of families with handicapped children were more dense as well. As predicted, there was greater boundary density in spousal networks in families with handicapped children. Differences in network reciprocity were inconclusive while the results indicate that families with handicapped children tended to rely more heavily upon multidimensional network contacts than did comparison families. The results are discussed in light of our understanding of stress, social support, and the social ecological context of families.     

Perceived Symbols of Authority and Their Influence on Compliance1

There are many variables that influence compliance. With regard to individuals making requests of others, Bickman (1974) found that the apparel of the person making the request significantly influenced whether another person complied with the request. This study evaluates other factors such as sex, age, and altruism in compliance. Subjects were involved in a replication of Bickman's dime and parking meter study. Results showed that the dress of the perceived authority not only affected the number of subjects who complied but also the type of compliance, the type of noncompliance, and the latency between request and compliance. Also, older subjects complied significantly more often than younger subjects in the role authority condition.     

College Freshman Performance: Summer Entrants vs. Fall Entrants

Entering college students and their advisors—high school and college personnel—frequently assert that the student will do better academically by entering college during the summer term rather than during the fall term with its many extracurricular activities. Comparing the academic performances over the first two quarters of 320 summer quarter entrants with 320 fall quarter entrants at the University of Tennessee yielded no significant differences for season entered. The ACT composite score for each student was held constant by using analysis of covariance. Significant differences for year entered—1962 or 1963—were apparently a function of the lack of reliability in grading practices. The academic performance of entering students did not benefit from summer quarter entrance.     

Duplex perception of cues for stop consonants: Evidence for a phonetic mode

When the (vocalic) formant transitions appropriate for the stops in a synthetic approximation to [spa] or [sta] are presented to one ear and the remainder of the acoustic pattern to the other, listeners report a duplex percept. One side of the duplexity is the same coherent syllable ([spa] or [sta]) that is perceived when the pattern is presented in its original, undivided form; the other is a nonspeech chirp that corresponds to what the transitions sound like in isolation. This phenomenon is here used to determine why, in the case of stops, silence is an important cue. The results show that the silence cue affects the formant transitions differently when, on the one side of the duplex percept, the transitions support the perception of stop consonants, and when, on the other, they are perceived as nonspeech chirps. This indicates that the effectiveness of the silence cue is owing to distinctively phonetic (as against generally auditory) processes.     

A Comparison of Two Group Contingencies on Teachers’ Use of Behavior-Specific Praise

The present study evaluated the effects of two reinforcement contingencies on teacher use of behavior-specific praise (BSP) in the classroom. An alternating treatments design was used to compare the implementation of both an independent and interdependent contingency to increase frequency of BSP delivery. Four general education elementary school teachers and their students participated. Teachers’ use of BSP and general praise, as well as, behavior-specific and general reprimands were evaluated. Data were also collected on students’ levels of academically engaged and disruptive behaviors. Both the independent and interdependent conditions resulted in higher frequencies of BSP and reduced the use of both general and behavior-specific reprimands. Student levels of academic engagement increased while disruption decreased across both contingencies. Results of the present study are discussed in terms of related literature and implications for applied practice.
