Effects of group contingent events upon classroom noise

The first study investigated a group control procedure for suppression of excessive sound-intensity levels in a regular public school classroom. Reinforcement consisted of a 2-min addition to the class gym period and a 2-min break after maintenance of an unbroken 10-min quiet period as monitored on a decibel meter. Transgressions of the sound limit (42 decibels) resulted in a delay of reinforcement by the resetting of the timer to the full 10-min interval. The results indicated that these procedures were highly effective in suppression and control of sound intensities. The second experiment utilized a similar procedure coupled with a procedure of eliminating out-of-seat behavior. Experiment III studied the effects of Exp. II procedures on a single student's out-of-seat behavior rate. All procedures were found effective.     

The value of relative-time-spent ratings in task-oriented job analysis

Recent studies have called for the abandonment of the relative-time-spent scale in task inventories. This recommendation is based on findings that the job profile created with the scale data is highly correlated with the profile created from a much simpler “Do you perform this task?” checklist. We examined this issue using 3 inventories and 42 jobs (N=2252). Profile correlations were computed on only the tasks actually performed by incumbents to avoid possibly inflated rs due to including irrelevant tasks. The specificity of task inventory items was proposed as an explanation for the high correlation between the two job profiles. Specificity of items was examined by looking at both the type (job duties versus tasks) and the amount (number of items in job profile and average number of items relevant to each job) of items used in the inventory. Correlations between time spent and checklist profiles were in the .80's and .90's regardless of the number of irrelevant tasks or the specificity of tasks. We agree with previous military research and conclude that the relative-time-spent scale has limited incremental utility beyond a dichotomous checklist.     

Lunchroom noise control using feedback and group contingent reinforcement

Reduction of noise levels in an elementary school lunchroom was examined as a function of feedback and feedback plus reinforcement using group contingency procedures. Feedback consisted of signals from a traffic light, with green indicating acceptable levels, yellow indicating levels approaching undesirable, and red indicating unacceptable levels. Other behaviors, including running, hitting, pushing, and kicking, were measured incidentally. Results indicate that feedback plus reinforcement was effective in reducing noise levels. Feedback only was also effective, but to a lesser degree. No response-response relationship was found to exist between noise level and the other behaviors.     

Recording online processes in task-oriented reading with Read&;Answer

We present an application to study task-oriented reading processes called Read&Answer. The application mimics paper-and-pencil situations in which a reader interacts with one or more documents to perform a specific task, such as answering questions, writing an essay, or similar activities. Read&Answer presents documents and questions with a mask. The reader unmasks documents and questions so that only a piece of information is available at a time. This way the entire interaction between the reader and the documents on the task is recorded and can be analyzed. We describe Read&Answer and present its applications for research and assessment. Finally, we explain two studies that compare readers’ performance on Read&Answer with students’ reading times and comprehension levels on a paper-and-pencil task, and on a computer task recorded with eye-tracking. The use of Read&Answer produced similar comprehension scores, although it changed the pattern of reading times.     

Promoting leadership behaviors in low performance-self-esteem women in task-oriented mixed-sex dyads1

Methods for promoting leadership behaviors in low performance-self-esteem women were explored in two studies. Female undergraduates were paired with male peers who had either very similar or much higher scores on the Performance-Self-Esteem Scale. The mixed-sex dyads in Study 1 were given either no leader, chance-based leader, or ability-based leader instructions. Study 2 included only the latter two conditions and allowed subjects preparation time between leader appointment and the dyadic interaction. All leader appointments were given to the female dyad member. Members' influence was measured by verbal interaction counts, decision outcome scores, and members' ratings. Both leader conditions were successful in promoting female leadership behavior in Study 2, as measured by verbal interactions, but neither was successful in Study 1. Results indicated that Study 2 females exercised a helpful leadership style and that Study 2 males were satisfied with their partners' role in the interaction.     

Coding position in a sequence by rhythmic grouping

It has been suggested that a perceived rhythmic organization may mediate remembering musical and other stimuli. This experiment examined whether or not Ss could register and remember position in a sequence using rhythmic grouping. Sixteen Ss heard tapped sequences 24–63 beats long, accented to encourage grouping by 4s. Ss tapped responses revealing whether or not they remembered the sequence length-the last tap’s position. Significantly more incorrect responses were off by multiples of 4 beats than by adjacent amounts; these frequent errors of whole rhythmic groups of 4 showed that Ss coded sequence length rhythmically. Ss proved 53% accurate over four response conditions, with individual’s scores ranging from 8% to 87%. It was concluded that Ss could count with rhythmic hierarchies, essentially equivalent to counting with a nonstandard number base, to code sequential position.     

Use of a task-oriented self-instruction method to support children in primary school with poor handwriting quality and speed

Two studies were conducted to investigate the effect of a task-specific self-instruction intervention to improve handwriting ability of children with poor handwriting quality in schools for regular education (Study 1) and children with poor handwriting quality in schools for special education (Study 2). Study 1 showed that children with poor handwriting quality who received handwriting intervention on an individual basis for three months improved on average more on quality of writing than control children without handwriting problems who did not receive intervention. In contrast, the control group improved more in speed of writing after the intervention period. At an individual level, three out of the seven children with poor handwriting quality before intervention were not classified as such anymore after the intervention period. Study 2 showed that after six months of intervention in a group setting children with poor handwriting quality improved their quality of writing more so than children with poor handwriting quality who had not received intervention. On speed of handwriting no significant group differences emerged. We conclude that the task-oriented self-instruction method applied in this study seems to improve especially the quality of handwriting, not speed, of children initially identified as having poor handwriting quality.     

Coding factors in transcription

Two experiments looked at aspects of stimulus grouping by trainee typists and tested for the possibility of response grouping. Manipulating text preview indicated that typing speed declined if the next word was not wholly on display but, conversely, there was little gain if it was displayed much in advance of its being typed. Some of the effect of practice was specific to the words actually typed: words not presented during practice were typed slower than practised ones; others given reinforced practice were typed quicker than the rest. An analysis of response latencies provides evidence that response grouping sometimes occurred.

A method for producing retinal exposures from a laser source in an awake, task-oriented S is presented. The technique allows for the measurement of rhesus monkey visual acuity immediately following exposures.     

Experiences in running a staff group

This study examines an activating mechanism of aggressive behaviour in young children. Many studies on attachment theories have indicated disorganised attachment as a significant risk factor for externalising problems and have explained the aetiology of disorganised attachment in terms of deficits in affect, behaviour and cognitive functions from a traumatic or inconsistent environment. Via the moment-to-moment analysis of the play therapy process with a three-year-old, this paper attempts to identify how these emotional, behavioural and cognitive factors interact in actual situations and can lead to an observable behaviour: aggressive behaviour. The findings from this study indicate that the child with disorganised attachment was going through a dual process, one with her therapist and the other with her internalised caregivers. When anxiety and an ambiguous social cue from an unpredictable situation were added to the child's repetition of previous attachment experience, this ‘click’ lowered the threshold of regulation of affect, behaviour and cognition. The child turned to disorganised and aggressive behaviour, relying on her physiological signals regarding the perceived threat. Finally, this paper describes how these difficulties can be channelled by symbolic play via displacement and containment.
