Evaluation of a Community-Based Peer-to-Peer Support Program for Parents of At-Risk Youth with Emotional and Behavioral Difficulties

Parents of children with emotional and behavioral needs frequently experience difficulty navigating community-based services for their child, as well as experience increased stress and parental strain. Peer-to-peer support programs are an emerging approach to assist these parents, and evidence suggests that they are effective in increasing parents’ perceptions of social support, self-efficacy, and well-being. However, these programs often focus on parents of youth with diagnosed mental health disorders, despite the potential benefit for parents of youth who are at-risk for significant emotional and behavioral problems. In the current study, we used a pre-post design to evaluate a community-based, peer-to-peer support prevention program delivered via telephone to parents (N = 139) of youth with emerging behavioral and emotional difficulties. We evaluated (1) whether the intervention was delivered as designed, (2) the pre- and post-intervention gains in social support and concrete support, and (3) whether parents’ level of participation in the intervention and program adherence predicted outcomes. Results indicated that the intervention was delivered as intended and resulted in increased parental perceived social support and concrete support over time. Furthermore, higher levels of parental participation and intervention adherence were associated with increases in perceived social support. Thus, findings suggest that it may be beneficial for parents of at-risk youth with significant emotional and behavioral difficulties to engage in a peer-to-peer phone support prevention program.     

The Virtuous Arguer: One Person,Four Roles

When evaluating the arguer instead of the argument, we soon find ourselves confronted with a puzzling situation: what seems to be a virtue in one argumentative situation could very well be called a vice in another. This paper will present the idea that there are in fact two sets of virtues an arguer has to master—and with them four sometimes very different roles.     

Peer Tutoring: Teaching Students with Learning Disabilities to Deliver Time Delay Instruction

This study evaluated the effectiveness of a peer-mediated constant time delay procedure for teaching written spelling to fourth- and fifth-grade students identified as learning disabled. The six peer tutors (each with learning disabilities) taught each other to produce the written spelling for 15 five- to eight-letter words using a 3-s delay and a visual model prompt. A multiple probe design across behaviors (word sets) was used to evaluate the procedure. Data were collected on the number of sessions to criterion, trials to criterion, number and percent of errors, and direct instructional time. The classroom teacher prepared students to serve as tutors using a describe-model-guided practice-feedback sequence. Pre- and post-measures were conducted of generalization of the tutoring procedure as well as observational learning by the tutors. Results indicated that (a) peer tutors reliably implemented the time delay procedure, and (b) the tutor-implemented time delay procedure was effective in teaching written spelling to students identified as learning disabled.     

Talker continuity and the use of rate information during phonetic perception

Research has shown that speaking rate provides an important context for the perception of certain acoustic properties of speech. For example, syllable duration, which varies as a function of speaking rate, has been shown to influence the perception of voice onset time (VOT) for syllableinitial stop consonants. The purpose of the present experiments was to examine the influence of syllable duration when the initial portion of the syllable was produced by one talker and the remainder of the syllable was produced by a different talker. A short-duration and a long-duration /bi/-/pi/ continuum were synthesized with pitch and formant values appropriate to a female talker. When presented to listeners for identification, these stimuli demonstrated the typical effect of syllable duration on the voicing boundary: a shorter VOT boundary for the short stimuli than for the long stimuli. An /i/ vowel, synthesized with pitch and formant values appropriate to a male talker, was added to the end of each of the short tokens, producing a new hybrid continuum. Although the overall syllable duration of the hybrid stimuli equaled the original long stimuli, they produced a VOT boundary similar to that for the short stimuli. In a second experiment, two new /i/ vowels were synthesized. One had a pitch appropriate to a female talker with formant values appropriate to a male talker; the other had a pitch appropriate to a male talker and formants appropriate to a female talker. These vowels were used to create two new hybrid continua. In a third experiment, new hybrid continua were created by using more extreme male formant values. The results of both experiments demonstrated that the hybrid tokens with a change in pitch acted like the short stimuli, whereas the tokens with a change in formants acted like the long stimuli. A fourth experiment demonstrated that listeners could hear a change in talker with both sets of hybrid tokens. These results indicate that continuity of pitch but not formant structure appears to be the critical factor in the calculation of speaking rate within a syllable.     

A computer system for automatically constructing stimulus material

A FORTRAN system for constructing various kinds of stimulus materials is described. A user enters the basic components of an experiment (stimulus items, presentation parameters, trial identifiers, etc.) as files, and uses the system to combine the basic files, automatically constructing the desired stimuli. The system contains file-manipulation functions for combining files (including factorial combination), functions for separating out parts of a file, and functions for randomizing files. The user can use the standard FORTRAN function-embedding and function-definition features to easily specify elaborate operations on the basic files to construct complex stimulus files.     

Spatial summation and the dynamics of warmth sensation

Various areal extents of the forehead and back were thermally irradiated at various levels of intensity. For any areal extent, the degree of apparent warmth grows approximately as a power function of intensity level; the larger the area, the smaller the exponent of the power function. Two families of psychophysical functions, one for the forehead, the other for the back, both show that the power functions extrapolate to a point of convergence in the neighborhood of the threshold for pain and tissue impairment. The rules that govern spatial summation of warmth reveal themselvesin the two families. Intensity and area trade one for the other to preserve the same level of warmth. At faint sensation levels, reciprocity is the rule of trading; but with increasing sensation level, area makes a weaker and weaker relative contribution to warmth, and, as a result, it takes a larger and larger percentage change in area to offset a given percentage change in intensity.     

Temperature can sharpen tactile acuity

The spatial acuity of the skin, as measured by two-point and two-edge limens, depends on the temperature of the objects that are touched. Cooling and warming the objects caused a marked improvement (an average of 41% in six subjects) in the skin’s acuity relative to thermally neutral stimulation. This improvement seems to be closely related to earlier observations that warm and cold objects placed on the skin feel heavier than do thermally neutral objects.     

Application of digital filters in the processing of eye movement data

Digital filter techniques have been applied to the analysis of eye movement data. Methods were developed to calculate eye velocity and eye acceleration in real-time from an electronystag-mogram (ENG) signal that was recorded using a one-pole RC high-pass filter in the preamplifier. Nonrecursive, finite impulse-response digital filters were designed to remove the effects of the RC high-pass filter and calculate the first and second time derivatives of the ENG signal, as well as remove high-frequency noise. Applying these new techniques to the analysis of vestibular nystagmus enables estimation of the transfer characteristics of the vestibuloocular system.     

Tactile vibration: Change of exponent with frequency

When cross-modality matches were made between a 60-Hz vibration and such other continua as electric current through the finger, number, force of handgrip, and both binaural and monaural loudness, the exponent of the power function for vibration was found to be about 1.0 at 60 Hz. The dependence of the exponent on frequency has been studied in a series of intramodality matching experiments. The exponent appears to reach its largest value in the vicinity of 30 Hz and its lowest value in the vicinity of 250 Hz. The highest value is roughly twice the lowest value. Over the low-frequency range, there is a suggestive similarity between the power functions for vibration and those for auditory loudness. As a vibration sensor, the ear may behave much like the finger.     

Cross-modality matching of brightness to loudness by 5-year-olds

The purpose was to determine whether 5-year-old children could match the brightness of a light to the loudness of a sound, and whether the resulting cross-modality function resembled the power function produced by adults. Each of five children adjusted the voltage on a 15D-W lamp to make the apparent brightness appear equal to the loudness of a 500-Hz tone, which the E set to eight different levels. The results resembled those of five adults who performed the same task.
