Complementarity of Linguistic and Prosodic Processes in the Intact Brain

Despite considerable speculation in the research literature regarding the complementarity of functional lateralization of prosodic and linguistic processes in the normal intact brain, few studies have directly addressed this issue. In the present study, behavioral laterality indices of emotional prosodic and traditional linguistic speech functions were obtained for a sample of healthy young adults, using the dichotic listening method. After screening for adequate emotional prosody and linguistic recognition abilities, participants completed the Fused Rhymed Words Test (FRWT; Wexler & Halwes, 1983) and the Dichotic Emotion Recognition Test (DERT; McNeely & Netley, 1998). Examination of the difference in ear asymmetries for these measures within individuals revealed a complementary pattern in 78% of the sample. However, the correlation between laterality quotients for the FRWT and DERT was near zero, supporting Bryden's model of "statistical" complementarity (e.g., Bryden, 1990).     

Content Analysis of Cognitive Bias: Development of a Standardized Measure

The purpose of this research was to develop a standardized content analytic measure of cognitive bias as conceptualized in Beck's (1987) cognitive theory of depression. In a pilot study it was determined that a written stimulus format was preferable to an audiotaped stimulus format with respect to comprehensibility. Valence and expectancy ratings collected in this pilot study also served as the basis for selection of items for the final measure, balancing positive and negative, expected and unexpected events. In study 2 open-ended written responses to questions about the main cause of each event, and the justifications for these attributions, were coded for indices of bias, defined (as in Cook & Peterson, 1986) as justifications that fail to cite covariation of the ascribed cause with the effect. Cognitive bias scores in Study 2 showed internal consistency (positive item-remainder correlations) and high interrater reliability. As predicted, justifications of attributions for expected events were more biased and less rational than were justifications of attributions for unexpected events.     

Corporal Punishment by American Parents: National Data on Prevalence, Chronicity, Severity, and Duration, in Relation to Child and Family Characteristics

We present data on corporal punishment (CP) by a nationally representative sample of 991 American parents interviewed in 1995. Six types of CP were examined: slaps on the hand or leg, spanking on the buttocks, pinching, shaking, hitting on the buttocks with a belt or paddle, and slapping in the face. The overall prevalence rate (the percentage of parents using any of these types of CP during the previous year) was 35% for infants and reached a peak of 94% at ages 3 and 4. Despite rapid decline after age 5, just over half of American parents hit children at age 12, a third at age 14, and 13% at age 17. Analysis of chronicity found that parents who hit teenage children did so an average of about six times during the year. Severity, as measured by hitting the child with a belt or paddle, was greatest for children age 5–12 (28% of such children). CP was more prevalent among African American and low socioeconomic status parents, in the South, for boys, and by mothers. The pervasiveness of CP reported in this article, and the harmful side effects of CP shown by recent longitudinal research, indicates a need for psychology and sociology textbooks to reverse the current tendency to almost ignore CP and instead treat it as a major aspect of the socialization experience of American children; and for developmental psychologists to be cognizant of the likelihood that parents are using CP far more often than even advocates of CP recommend, and to inform parents about the risks involved.     

Predictors of therapeutic response to treatments for depression: a review of electrophysiologic and dichotic listening studies

There are few clinical or biologic predictors of response to treatments for depression. This article reviews growing evidence that electrophysiologic and neurocognitive measures of brain function may be of value as predictors of therapeutic response to antidepressants. Initial studies using dichotic listening, quantitative electroencephalography, or event-related brain potential measures have found differences between treatment responsive and nonresponsive subgroups of depressed patients. The neurophysiologic basis for these differences and the potential clinical utility of electrophysiologic and dichotic predictors of treatment outcome remain to be determined in future studies.     

Economic practices of Jesus movement groups

This paper examines in detail the multitude of ways used by Jesus Movement organizations to raise money to fund their many activities. The research was provoked by sharp differences between fund‐raising methods used by the two largest and well known JM organizations—the Children of God (now called The Family) and Christ Communal Organization (a pseudonym for a group called Shiloh). The COG mainly relied on various forms of public solicitation, while Shiloh depended on working for others and themselves in an effort to become self‐supporting. Seven other JM groups were examined to find out what patterns of support were most prevalent, and to examine possible relationships between sustenance activities and theological developments within the groups. A large number of experimental approaches were taken by JM groups trying to sustain themselves during their sometimes tumultuous histories, leading to a number of general conclusions.     

Individualism-collectivism and self-concept: Social or contextual?

The cultural constructs of individualism and collectivism (I-C) have been closely identified with different conceptions of the self. In contrast to autonomous, abstract self-concepts, it has been argued that collectivists have concepts of self which are interdependent with others and connected with particular contexts. This study investigated the extent to which spontaneous social and contextual self-concepts were connected to each other and to individual-level I-C measures. Questionnaires were administered to adult employee samples in Australia and South-East Asia (N = 581). Although closely intertwined, social and contextual statements were able to be independently tested in relation to I-C. I-C was primarily related to the social-autonomous dimension of self. Controlling for social self-responses, contextual self-concepts were not independently related to any of the measures of I-C.     

Perceptual asymmetry differences between major depression with or without a comorbid anxiety disorder: a dichotic listening study.

Predictions that anxious and nonanxious depression would differ in perceptual asymmetry (PA), as well as in sensitivity for perceiving emotional words, were evaluated using dichotic listening tasks. A total of 149 patients having a major depressive disorder (51 with and 98 without an anxiety disorder) and 57 healthy controls were tested on fused-word and complex tone tasks. The anxious and nonanxious depression groups showed a consistent difference in PA across tasks; that is, the anxious group had a larger left-ear advantage for tones and a smaller right-ear advantage for words when compared with the nonanxious group. There was no group difference in sensitivity for perceiving emotional words. Patients having an anxious depression appear to have a greater propensity to activate right than left-hemisphere regions during auditory tasks, whereas those having a nonanxious depression have the opposite hemispheric asymmetry.     

Do tricyclic responders have different brain laterality?

A previous study showed that depressed patients who improved with tricyclic antidepressant medication had dichotic complex tones test results suggesting right-hemisphere dysfunction relative to nonresponders and controls (G. E. Bruder et al., 1990). A new sample of 68 depressed patients completed dichotic consonant-vowel (CV) and complex tones (CT) tests and then were treated with imipramine or placebo. A significant Ear x Test x Treatment x Response interaction was accounted for by significantly poorer left-ear accuracy for CVs among imipramine responders compared with nonresponders, placebo responders, and controls. CV left-ear accuracy was also significantly greater among placebo responders than placebo nonresponders and controls. The results only partially replicate the prior study in that evidence of right-hemisphere dysfunction in tricyclic responders was seen for the CV test but not the CT test.     

AUGMENTING SIMPLIFIED HABIT REVERSAL IN THE TREATMENT OF ORAL-DIGITAL HABITS EXHIBITED BY INDIVIDUALS WITH MENTAL RETARDATION

We investigated whether a simplified habit reversal treatment eliminates fingernail biting and related oral-digital habits exhibited by individuals with mild to moderate mental retardation. Although simplified habit reversal did little to decrease the target behaviors for 3 of 4 participants, simplified habit reversal plus additional treatment procedures decreased the behavior to near-zero levels for all participants. These procedures included remote prompting, remote contingencies involving differential reinforcement plus response cost, and differential reinforcement of nail growth. Limitations of habit reversal for individuals with mental retardation along with directions for future research involving therapist-mediated treatment procedures, particularly those involving remote prompting and remote contingencies, are discussed.
