How school-aged students define stuttering and stammering

Fifty students from each of the grades 2, 4, 6, 8, 10, and 12 were asked to complete a questionnaire containing the following three questions: 1) What is stuttering? 2) What is stammering? 3) How did you know that? Analysis of their responses indicated students were more familiar with stuttering as opposed to the term stammering. From grade 6 onward, we can expect at least three-fourths of the students to define stuttering as a disruption of speech consisting chiefly of sound or syllable repetitions. Only about one-fourth of students in grade 6 and above defined stammering as a speech disruption. This disruption was characterized chiefly by repetitions, injections, and pauses. Most of the students were unable to specify how they learned the definitions. The few who did identified family and friends as their chief source of knowledge.     

‘Random’ saccadic eye movements during verbal-linguistic and visual-imaginal tasks

Previous research has suggested that questions eliciting visual imagery are associated with lower rates of saccadic eye movements as compared to questions eliciting verbal processes. Two experiments reported here examined the roles of external visual stimulation and speech output in this effect. In both experiments, questions designed to elicit verbal-linguistic or visual-imaginal processing, and which required either syntactically complex or simple responses, were administered while eye movements were recorded by electrooculography. In experiment 1, 42 subjects responded while viewing either the interviewer's face or a gray oval on a video monitor. Imaginal questions elicited a lower rate of eye movements than did verbal questions regardless of the display on the monitor. In experiment 2, 17 subjects responded in conditions of light and darkness. Imaginal questions elicited lower rates of eye movements in both light and dark. Neither cognitive mode nor speech output requirements interacted with stimulus conditions in either experiment. The failure of visual conditions to influence the verbal-imaginal difference in eye movement rate is viewed as inconsistent with a visual interference interpretation of the relationship of eye movements to cognitive activity. Alternate interpretations are discussed.     

Social skills: A review of cognitive-behavioral training procedures with children

Thirty-one studies utilizing cognitive-behavioral procedures to train social skills were reviewed. The review was organized around six methodological issues: (a) age of subjects; (b) training procedures; (c) outcome measures; (d) research design; (e) evidence for generalization; and (f) social validation. Suggestions for future applied research are discussed, such as investigations regarding developmental changes in socially skilled behavior, increased use of multiple dependent measures, more intensive programming for generalization, and the establishment of the social importance of the effects of social skills training programs.     

Cluster analysis in school psychology: An example

This investigation demonstrates the use of Ward's method of cluster analysis to uncover the underlying classification structure in a group of children (N = 200) referred for psychological evaluations by their public school teachers. Data were acquired on children's intellectual development, academic achievement, and social adjustment. The cluster solution identifies six groups of children which are statistically distinct. All three measurement areas are important in distinguishing among the different groups. The six-group solution accounted for appreciable amounts (95%) of the variability in the three measurement areas. Implications for psychologists working in the schools are discussed.     

Intelligence and teachers' ratings as predictors of abstract and concrete learning

This study concerned the prediction of children's learning with an individual measure of intelligence and teachers' evaluations. Eight abstract and eight concrete nouns were paired with nonsense geometric figures and presented to 60 elementary school children in a three-trial paired-associate (PA) learning task. Subjects' IQ scores on the Wechsler Intelligence Scale for Children-Revised and teachers' ratings of learning proficiency were used to predict children's performance on the PA task. Multiple correlations favored abstract learning with verbal scale intelligence, accounting for the majority of the variability. Teachers' ratings provided a surprising degree of predictive efficiency for abstract recall which was redundant with verbal intelligence.     

Speech and bimanual hand organization in adult stutterers and nonstutterers

A multivariate approach was used to investigate the relationship between speech fluency and bimanual handwriting in right-handed male stutterers and nonstutterers. Handedness was determined by the Harris Test of Lateral Dominance. Subjects were required to write the numbers 1 through 12 simultaneously, as quickly as possible. Speech measures were derived from the Stuttering Severity Instrument and from a reading passage. Stutterers performed more poorly than nonstutterers on all speech measures. There were no differences in bimanual handwriting performance for the dominant hand. However, stutterers performed more poorly than nonstutterers in nondominant handwriting. There were no relationships between speech measures and bimanual handwriting for stutterers or nonstutterers. Some stutterers performed better on the handwriting task than did some nonstutterers. It is suggested that disorganization in interhemispheric integration functions may be a more fundamental problem in stuttering than is incomplete cerebral dominance.     

The Adams and Reis observations revisited

This experiment was designed as a replication of the Adams and Reis (1971, 1974) experiments, which posited a direct relationship between frequency of stuttering and the number of “off-on” laryngeal adjustments during speech. Twenty adult stutterers read two prose passages equivalent in length, word length, and semantic content. The first passage contained a normal distribution of syllable-initial voiced and voiceless consonants whereas the second contained only voiced phonemes. The results demonstrated significantly greater stuttering during reading of the all-voiced passage (P?0.05). These results did not confirm the earlier observations of Adams and Reis and mitigate the hypothesized relationships between stuttering frequency and “off-on” laryngeal adjustments.     

Converging evidence for the functional significance of imagery in problem solving

Two kinds of explanations have been offered for the process by which three-term series problems are solved, one in terms of linguistic principles and the other in terms of visual-spatial imagery. Two experiments are reported in which three different classes of operations are brought to bear on the problem: (1) Manipulation of stimulus attributes (characteristics of problems), (2) manipulation of variables that selectively encourage or inhibit the use of imagery (facilitating instructions; the suppression of visualization by reading), and (3) measurement of relevant individual differences (spatial-reasoning ability). All of the results indicate that imagery plays a functional but not a necessary role in the solution of three-term series problems; it is suggested that imaginal representation is functional because it reduces the load on memory. An adequate explanation of problem-solving will have to address certain general issues, such as the diversity of forms of cognitive representation and differences within and between individuals in the choice of problem-solving strategies.     

Stimulus probability and prediction outcome as determinants of choice reaction time: Some procedural considerations

Effects of stimulus probability and prediction outcome on two-choice reaction speed (CRS) were determined when a frequency imbalance was reversed half-way through 300 samples of a 70/30 stimulus distribution and when the same 70/30 distribution was sampled for 1200 trials. Prior to each presentation Ss made a prediction; following each presentation Ss identified the stimulus by pressing a right-hand or left-hand trigger. CRS was faster to correctly predicted stimuli, and faster to the more probable stimulus. Ss who were informed of the frequency imbalance reacted significantly faster than Ss who were not. Both practice and boredom effects were demonstrated by using the extended number of trials. CRS was faster during the second session of 300 trials than during the first; after two sessions, CRS was slower during the second half of two additional sessions.     

Between daʿwa and Dialogue: Religious Engagement in Muslim-minority Environments

ABSTRACT

Muslim engagement in interfaith and intercultural dialogue began in earnest after the turn of the twenty-first century in response to the rise of global jihad. Both dialogue and jihad are outgrowths of da?wa, the call or mission of Islam, the principal mode of modern Islamic activism. The foundations were laid in the later part of the twentieth century by Muslim intellectual-activists living in non-Muslim environments, who played a special role in conceptualizing the new notion of dialogue and its relation to da?wa. This essay focuses on four pioneering figures, two from the indigenous context of India – the modernist Asghar Ali Engineer and the reformist ?ālim Wahiduddin Khan, and two from the diaspora milieu of the West – the Palestinian-American academic activist Ismail Raji al-Faruqi and the European Muslim spokesman Tariq Ramadan. Each represents a distinct religious orientation that also reflects a different phase in the evolution of modern Islamic discourse. Taken together, these intellectual-activists chart the trajectory of modern Islam from the early pre-Islamist liberal hopes to the present post- and neo-Islamist efforts to navigate between Western-dominated globalization and Islamist jihadism.
