The effects of labeled and unlabeled praise upon lower and middle class children

This study investigated the relative effectiveness of two types of content of praise, labeled and unlabeled, with lower and middle class children. Following two brief observation periods designed to assess differences in the frequency with which lower and middle class mothers employed labeled and unlabeled praise, each mother played the marble-in-the-hole game with her child. Half of the mothers in each group were given labeled and half were given unlabeled praise statements to make contingent upon their child dropping marbles in a particuler hole. The results indicated that the children were more responsive to labeled than to unlabeled praise. The mothers from the two socioeconomic groups did not differ in the frequency with which they employed labeled and unlabeled praise in the initial observation periods.     

A vigilance task sensitive to the effects of stimulants, hypnotics, and environmental stress: The Scanning Visual Vigilance Test

The Scanning Visual Vigilance Test is a variable-length detection test designed to assess the ability of individuals to maintain visual alertness for sustained periods of time. The test was designed to be sensitive to changes in vigilance produced by subtle variations in performance, such as those produced by low doses of centrally acting food constituents, drugs, or environmental stress. The test has been shown to be sensitive to the effects of stimulants and sedatives, as well as cold stress and sleep loss. It requires the subject to continuously scan a video monitor to detect the occurrence of infrequent stimuli that are difficult to detect. The number of stimuli correctly detected, false alarms, and reaction times are recorded. The stimulus is a small rectangle displayed for 2 sec at random locations on a darker region of a video monitor at random or pseudo-random times. The brightness of the stimulus can be adjusted for each subject individually on an automated threshold detection test. Training and test session length are defined by the experimenter. Hardware requirements are an IBM-compatible personal computer (286 or higher) with a color or grayscale VGA monitor.     

on the acoustic analysis of primate vocalizations

The acoustic theory of speech production relates articulatory maneuvers to acoustic attributes of speech. Some procedures are discussed that make use of this theory to analyze the vocalizations of nonhuman primates. These procedures make use of sound spectrograms, oscillograms, and computer-implemented analogs of the primate vocal apparatus as well as anatomical measurements. The use of these techniques in recent studies of nonhuman primate vocalizations is reviewed. These studies show that nonhuman primates lack the anatomical apparatus that is necessary for the production of the full range of human speech. Some unresolved questions concerning the structure of nonhuman primate utterances are discussed with regard to human linguistic ability.     

A prevocational training project for emotionally disturbed adolescents

Adult inpatient populations, trained to develop a repertoire of work-related skills such as tracking and following directions, utilizing emotional controls, relating to the world in a realistic manner, as well as acceptance of supervision, grooming, punctuality, and attendance. These skills eased their transition to the community and assisted in a more positive existence once within that community as compared to their untrained cohort. Additionally, the process of vocational training has been demonstrated to have therapeutic benefits. This project used many of the same adult training principles but applied them to an adolescent inpatient population. A vocational training project using specific behavioral interventions resulted in comparable improvement for adolescent subjects otherwise evidenced in adult patients' work-related skills and abilities. This training project was conducted yearly, 32 h per week for 10 weeks for 4 years. The project combined actual work experience, classroom time and behavioral interventions and rewards. A 16 × 10 analysis of variance was computed to assess improvement in work-related skills and abilities. The analysis yielded and F = 2.57, p < 0.01, suggesting the efficacy of the behavioral interventions when applied to adolescent inpatient populations. © 1997 John Wiley & Sons, Ltd.     

Aggression and sexuality in relation to toddler attachment: Implications for the caregiving system

Sexuality and aggression emerge in the second year of life as important motivational systems that organize substantial aspects of the toddler's behavior, affecting the operation of the attachment system and transforming the parents' perceptions and behaviors toward the child. The interconnection between different motivational systems in the parent and child is discussed as an important dimension in broadening our understanding of attachment in the context of the caregiving system. Normative and clinical examples are presented to illustrate how aggression and sexuality affect attachment and caregiving behaviors and representations in toddlerhood.     

Online health communication about human genetics: perceptions and preferences of internet users.

Unprecedented advancements in human genetics research necessitate keeping the public abreast of new information, applications, and implications and the Internet represents an important method of communicating with the public. Our research used cross-sectional self-report survey data collected from a diverse convenience sample of 780 Internet users in two states. Multivariate regression analysis explored the relationships between experiences, perceptions, and preferences for online health and genetics communication. Online health information seeking was associated with previous genetic information seeking, comfort with online genetic communication, perceived risk for genetic abnormality, being female, and having more education. Comfort with online genetics communication was associated with a preference for online genetic information, previous online health and off-line genetics information seeking, having a healthy lifestyle, believing in the positive impact of human genetics research, and being female. Perceiving online health information to be accurate was associated with preferring the Internet for genetics communication, being older, less educated, and perceiving Internet use as anonymous. Preferring online genetics communication to other communication channels was associated with perceiving online health information as accurate, being comfortable receiving online genetics information, having lower intrinsic religiosity, and being male. The implications of findings for Web-based health message design are discussed.     

Maternal Meta-Emotion Philosophy Moderates Effect of Maternal Symptomatology on Preschoolers Exposed to Domestic Violence

Exposure to domestic violence in the preschool years is consistently associated with children’s heightened risk for developing behavior problems. Maternal meta-emotion philosophy (awareness, acceptance, and coaching of children’s emotions) has been identified as an important protective factor in children’s development of internalizing and externalizing behaviors following exposure to domestic violence. However, mothers who are victims of domestic violence often experience symptoms of depression, anxiety, and post-traumatic stress, which may undermine their capacity to respond to their children’s negative emotions. The present study examines the protective role of maternal meta-emotion philosophy among mothers and preschool-aged children exposed to domestic violence. Participants were 95 mothers (mean age?=?31.78) and their preschool-aged children (mean age?=?4.11) who had witnessed domestic violence involving their mothers. Multiple regression analyses, controlling for family socioeconomic status and child exposure to interpersonal violence in the family, indicated that maternal symptomatology was positively associated with children’s internalizing problems. In addition, maternal awareness and coaching of children’s negative emotions was found to moderate relations between maternal symptomatology and children’s internalizing behaviors, and maternal awareness of children’s negative emotions was found to moderate relations between maternal symptomatology and children’s externalizing behaviors. These findings expand our understanding of maternal meta-emotion philosophy as a protective factor for preschoolers who have witnessed domestic violence.
