A perceptual comparison: All-voiced versus typical reading passage read by children

The present investigation tested the modified vocalization hypothesis (Hutchinson and Brown, Journal of Fluency Disorders, 1978, 3, 149) in young stuttering subjects. In this study, stuttering children ages 7–13 yr were instructed to read two experimentally constructed passages. One passage contained both voiced and voiceless phonemes; the second passage was constructed using only voiced phonemes. Results indicated there was neither a quantitative nor a qualitative difference in the stuttering blocks during the reading of either experimental passage. These results would appear not to be supportive of the modified vocalization hypothesis in children; however, as has been indicative of similar studies, 8 of 22 subjects did demonstrate more dysfluencies during the reading of the passage that contained both voiced and voiceless phonemes.     

Effects of background anger,provocation, and methylphenidate on emotional arousal and aggressive responding in attention-deficit hyperactivity disordered boys with and without concurrent aggressiveness

We investigated the effects of background anger, provocation, and methylphenidate on emotional, physiological, and behavioral responding in children with attentiondeficit hyperactivity disorder (ADHD) with and without concurrent aggression. Our study revealed that ADHD boys showed more emotional and physiological distress when exposed to an interaction in which an administrator chastised each boy's favorite counselor, compared to a friendly interaction between the two adults. The background anger manipulation did not affect the aggressive behavior of the boys against an opponent in an aggressive game. High-aggressive (HA) ADHD boys were more likely to respond to provocation with aggression than low-aggressive (LA) ADHD boys, but only LA boys showed increased physiological reactivity with increasing provocation. Methylphenidate resulted in increased heart rates under all conditions and did not interact with any of the other findings.This project was conducted while the first author had the support of National Institute of Alcohol Abuse and Alcoholism grant AA 06267.The authors wish to thank the staff members of the 1987 Summer Day Treatment Program who assisted in conducting this project.

Risk–need–responsivity and its application in behavioral health settings: A feasibility study of a treatment planning support tool

The risk–need–responsivity (RNR) model suggests several key practices for justice‐involved populations under correctional supervision. Behavioral health treatment planning aligned with RNR principles for offender populations with co‐occurring mental health and substance use disorders (CODs) could be one method for integrating RNR into clinical care. To explore a unique approach to working with behavioral health and RNR principles, the authors implemented a mixed‐methods feasibility study of the acceptability, usability, and utility of a newly developed RNR treatment planning support tool (RNR TST). The tool was implemented in a re‐entry program serving adults with co‐occurring mental health and opioid use disorders. Chart reviews of RNR TSTs (N = 55) and a focus group (N = 14 re‐entry clinical staff) were conducted. Ninety‐six percent of the RNR TSTs incorporated the use of a validated risk–need assessment and 70% of the RNR TSTs were semi‐complete to complete. Focus group interviews highlighted behavioral health staff perspectives on the acceptability, usability, and utility of the RNR TST. This novel RNR TST has the potential to assist behavioral health providers in integrating RNR principles into treatment planning. Further development and testing are needed to determine its impact on client care and outcomes.     

Mothers' Perceptions of Infants Labelled ‘Depressed’

Forty-four depressed and non-depressed mothers participated in a videotaped interaction with their own infant and then rated the videotape using the Infant Stereotyping Scale and the Interaction Rating Scale. In addition, one half of the mothers rated a videotape of an unfamiliar infant who was labelled psychologically ‘depressed’ and the other half rated a videotape of the same infant with no label given. Both the depressed and non-depressed mothers rated the ‘depressed’ labelled infant more negatively than the non-labelled infant on the attributes of physical potency, cognitive competence, sociability and difficult behaviour. Physical appearance was the only rating that was not biased by the ‘depressed’ label. Mothers' ratings of their own infants were more positive than their ratings of the non-labelled stimulus infant. Depressed mothers did not see their infants more negatively except on one rating. They rated the physical appearance of their own infant more negatively than non-depressed mothers.     

Differential impact of parenting sick infants

Parenting a newborn infant has been identified as a significant stressor, and parenting a sick infant evokes an even greater stress. This study evaluated the differential impact of parenting infants with interrupted infantile apnea vs. extremely low birth weight infants. These infants were compared to normal infants on the Bayley Scales of Infant Assessment and the Parenting Stress Index when the infants were 6 months old. Significant effects on the mental index revealed that the low birthweight infants performed more poorly than did the other groups. A stepwise multiple discriminant analysis on the Parenting Stress Index suggested that child adaptability, maternal restrictions, isolation, and health were significant stressors. Mothers of apneic infants were affected most severely by their child's illness. The lower educational level of these mothers may have influenced these findings.     

Masked priming of prefixes and the influence of spelling-meaning consistency

Two experiments are reported which examined whether a prefixed word can be primed by a word sharing only the prefix letters in a masked priming paradigm. In addition the studies examined whether the size of the priming effect is influenced by the consistency with which a prefix letter pattern appears in real prefixed words. The ratio of real prefixed words to all words containing a prefix letter pattern was calculated and used to identify high-consistency prefixes, which are frequently used as prefixes (e.g., UN in UNHAPPY) and rarely appear as pseudoprefixes (e.g., UNCLE), and low-consistency prefixes, which appear in many pseudoprefixed words (e.g., DE in DESERT) but fewer truly prefixed words (e.g., DECODE). In Experiment 1, decision latencies for both types of prefixes were facilitated when real prefixed target words were preceded by real prefixed prime words in a short SOA masked priming paradigm, although the size of the priming effect for low-consistency prefixes was similar in size to that for orthographic controls. In Experiment 2, real prefixed target words were preceded by pseudoprefixed prime words. Facilitation in performance remained for high-consistency prefixes but was absent for low-consistency prefixes. These results support models of morphological processing that are sensitive to the statistical nature of the relationships between orthographic and semantic representations in a language.     

The factor structure of the Anxiety Sensitivity Index among Northern Plains Native Americans

Within our current research climate, an emphasis has been placed on examining the cross-cultural applicability of psychological tools, and exploring their utility with people of different backgrounds. Within this line of investigation lies the risk of classifying people too broadly and masking important regional, tribal, or dialectical differences. This may be particularly potent among Native Americans, given the number of distinct indigenous entities. This study examined the psychometric characteristics of the Anxiety Sensitivity Index with a tribally homogeneous sample, as compared to previous tribally-heterogeneous and majority culture findings. Results suggested that data from a homogeneous Native American sample poorly fit factor solutions reported from heterogeneous Native American and Caucasian samples, and favored a unifactorial solution. Implications for assessment with Native American peoples are discussed.     

Aerobic physical activity effects on psychological well-being in low-income Hispanic children

Psychological well-being has been generally associated with vigorous aerobic activity and structured aerobic activity in adolescents and children. Low-income children are at greater risk than the general population for experiencing high environmental stress and increased mental health problems. This study investigated the effects of a structured physical fitness program on psychological well-being in low-income Hispanic children. A total of 66, 33 girls, 33 boys, in Grade 4 were randomly assigned to either an Aerobic intensity (n = 34) or a Control intensity physical activity program (n = 32) for 6 wk. Psychological well-being was defined as scores on trait anxiety, depression, and self-esteem, measured, respectively, by the Trait Anxiety Inventory, Beck Depression Inventory, and Rosenberg Self-esteem scale. Analysis showed the children in the Aerobic intensity program significantly (p < .05) improved their cardiovascular fitness as measured by the PWC170 test. After the program was over, the children in this Aerobic group reported significantly (p < .05) less depression. The main effect for self-esteem reflected the Aerobic group's greater self-reported self-esteem. No differences were found on trait anxiety. The effects on depression and self-esteem may only be attributed to the cardiovascular improvement given the higher intensity physical activity program because causation was not assessed here.     

Training requirements and retention characteristics of serial list organization by macaque monkeys

This work evaluated the prospect that organizational accounts of the retention of list information by monkeys might be an artifact of familiarity with conditional relationships. Seven sophisticated macaques were trained on four five-item lists. Each acquisition selectively excluded one of the internal conditional pairs of the typical four-problem sequence (AB,BC,CD,DE) that defines a five-item serially ordered list. Then, all possible novel pairings and the trained pairs appeared together in a test. After this, the previously omitted pair was trained and animals were retested. On all tasks, initial tests revealed little organization and much intersubject variability of characteristic choice strategies, but subsequent inclusion of all four conditional pairs always yielded organized serial choice. On both the four-problem tests and in a later retention, errors were directly related to interitem distance between the objects paired on test trials. These results helped to specify the conditions required for demonstration of non-human primate analogs of transitivity, and showed that even sophisticated monkeys organize information in retention only if they know all interitem relationships.
