Is desynchrony tolerance adaptable in the perceptual organization of speech?

Speech signal components that are desynchronized from the veridical temporal pattern lose intelligibility. In contrast, audiovisual presentations with large desynchrony in visible and audible speech streams are perceived without loss of integration. Under such conditions, the limit of desynchrony that permits audiovisual integration is also adaptable. A new project directly investigated the potential for adaptation to consistent desynchrony with unimodal auditory sine-wave speech. Listeners transcribed sentences that are highly intelligible, with veridical temporal properties. Desynchronized variants were created by leading or lagging the tone analog of the second formant relative to the rest of the tones composing the sentences, in 50-msec steps, ranging from 250-msec lead to 250-msec lag. In blocked trials, listeners only tolerated desynchronies <50 msec, and exhibited no gain in intelligibility to consistent desynchrony. Unimodal auditory and bimodal audiovisual forms of perceptual integration evidently exhibit different temporal characteristics, an indication of distinct perceptual functions.     

Reliability and validity of gain scores considered graphically

The ordinary gain score, g, is defined as g = x2-x1, where x1 is the pretest score and x2 is the posttest score. The present study extends and refines previous research on the reliability and validity of gain scores. Using particular values as stated in the tables and graphs, the pre- and posttest reliabilities, pre- and posttest validities, ratios of pretest to posttest standard deviations, and correlations between the pretest and posttest were varied systematically to examine the effects of these parameter configurations on gain scores' reliability and validity. Results plotted graphically provide insight via visual interpretation not easily inferred using only values from a table. One interesting finding was that the reliability of a gain score can be at a maximum when the validity is at a minimum. Another is that a high correlation between pre- and posttest was beneficial to the validity of the gain score but detrimental to its reliability. By identifying the situations in which gain scores can be reliable and valid, findings inform researchers when gain scores should or should not be used.     

Frequency and duration of mood fluctuations: effects of dependency, self-criticism, and negative events

Few studies have examined the relation between depressive vulnerability factors and the duration of symptom disturbance, defined as the length of time during which mood states are elevated above a certain threshold. We examined the duration of mood disturbances in male (N=31) and female (N=71) college-aged individuals who completed mood checklists twice weekly for 10 weeks. Results showed that dependency and self-criticism were related to the mean severity of ratings across all checklists and the mean duration of disturbances, as well as the number of disturbances lasting at least 7 or 14 days. Some evidence for the congruency model was found. Dependency and self-criticism moderated the relation between vulnerability congruent hassles and mood. Sensitivity analyses showed that altering the threshold at which symptom scores were designated as symptom disturbances did not affect the pattern of results for dependency and self-criticism. Results have implications for the debate concerning the relation between vulnerability factors and depressive severity.     

The Atrocity Paradigm and the Concept of Forgiveness

In this article 1 discuss Claudia Card's treatment of war rape in relation to her discussion of the victim's moral power of forgiveness. I argue that her analysis of the victim's power to withhold forgiveness overlooks the paradoxical structure of witnessing, which implies that there is an ungraspable dimension of atrocity. In relation to this ungraspable element, the proposal that victims of atrocity have the power to either offer or withhold forgiveness may have little relevance.     

A Preliminary Study Using the Substance Abuse Subtle Screening Inventory—Adolescent Form as an Outcome Measure With Adolescent Offenders

The authors describe a preliminary study using the Substance Abuse Subtle Screening Inventory‐Adolescent Form (SASS‐A; E Miller, 1994) as an outcome measure with adolescent offenders. Results indicate that the SASSI‐A can be successfully used as a treatment planning tool as well as a measure to evaluate programs.     

Stop-Think-Relax: An Adapted Self-Control Training Strategy for Individuals with Mental Retardation and Coexisting Psychiatric Illness

Published self-instructional techniques for stress/anger management for those with mental retardation and developmental disabilities are often impractical due to the demands of complex instructional sequencing and of applying the technique during distressing situations. The development and implementation of an adapted, self-instructional, self-control technique employing a simple, 3-step method, reinforced by iconic visual cues, will be presented. The application of this strategy in individuals with mental retardation and concurrent mental illness will be reviewed in 3 detailed clinical cases. The Stop-Think-Relax strategy is a highly versatile and easily taught method for self-control that can be successfully applied in adults with limited cognitive capacities and with coexisting psychiatric features.     

Sensitivity of passive approach during preference and reinforcer assessments for children with severe and profound intellectual disabilities and minimal movement

We evaluated the use of passive approach to assess preferences of two children, with severe and profound intellectual disabilities. Both children had physical challenges and exhibited minimal physical movement. We also compared the relative reinforcing effects of the identified high and low preference stimuli for a switch pressing response, and for a more passive looking response. High and low preference stimuli were identified for both children. Moreover, the high preference stimulus maintained higher rates of responding than the low preference stimulus for both children for the passive looking response, but not for switch pressing. The study extended the use of passive approach to assess preferences and identified the choice of target response as a potential limiting factor during reinforcer tests for these children.
