The smoke reflex in rabbits an example of autonomic control of cardiorespiratory function

This study was undertaken to elucidate aspects of autonomic behavior as reflected in the “smoke reflex” in rabbits. Allowing smoke to envelop the nostrils of a rabbit resulted in prompt apnea, bradycardia, diminution of peripheral pulse and elevation of systemic blood pressure. Atropine and vagotomy, or both, mitigated the bradycardia, but the combined effect of propranolol and vagotomy was required to abolish bradycardia. Phenoxybenzamine (dibenzyline) alone blocked only the peripheral vasoconstriction and pressor response. The combination of vagotomy, propranolol and phenoxybenzamine blocked all manifestations of the reflex with the exception of apnea. A classical concept holds that responses of the autonomie nervous system must be either distinctly adrenergic (sympathetic) or cholinergic (parasympathetic), and that visceral regulation is achieved by an antagonism between the two. This study introduces contrary evidence and demonstrates that in certain adaptive behavior there is a patterned response that includes activation of discrete elements of both cholinergic and adrenergic divisions, as well as inhibition of one component of the latter.     

Correspondence in parents' and children's concepts of god: Investigating the role of parental values,religious practices and executive functioning

This study examined the extent to which children's concepts of God correspond with their parents' concepts of God. It also examined how parent-context factors and children's executive functioning relate to parent–child conceptual similarity. Parent–child dyads from varied religious and racial backgrounds participated. Dyads had the greatest conceptual similarity concerning God's mind-dependent functions. Though correspondence between parents and children was lowest concerning God's body-dependent functions, dyads were more similar about those functions when parents engaged in more frequent religious practices with their child and thought God was important. Children's concepts of God were unrelated to religious practices, and parent–child conceptual similarity was unrelated to children's age and executive functioning. Simply put, variation among parents' anthropomorphic concepts of God drove variation in parent–child conceptual similarity. Overall, these findings suggest that embodied concepts of God may be most sensitive to cultural input and that socialization practices provide greater insight into parents' anthropomorphic concepts.     

Learning From Fantasy and Real Characters in Preschool and Kindergarten

In three experiments, 3½- to 6-year-old children were presented with analogical problems in which the protagonists were either real people or fantasy characters. Children were more likely to transfer solutions from the stories about real people rather than the stories about fantasy characters. These results suggest that the use of a fantasy character might not be an effective strategy for teaching children information that is meant to be applied to the real world.     

The Role of Gender in Young Children’s Selective Trust of Familiar STEM Characters

Female characters are less likely to engage with science, technology, engineering, and math (STEM) content than male characters on young children’s television shows. The current study examined how preschool-aged children’s selective trust of male and female characters to teach STEM differed by child gender, and how trust relates to children’s character identification. Forty-eight 3- to 6-year-old children’s selective trust of male and female characters to teach STEM content, gendered character identification, and personal interest in STEM activities was measured. Boys and girls had similar interest in STEM and had greater identification with same-gender characters. Although boys had significantly greater trust in male characters, girls had similar levels of trust in male and female characters. Overall, children had greater trust of male characters to teach STEM content, but this effect was driven by boys, indicating identification and selective trust are related, but not identical constructs. The discussion considers how representations of female and male characters on television may impact children’s trust of educational media characters to teach STEM.     

A combined planning and self-efficacy intervention to promote physical activity: a multiple mediation analysis

Many individuals are motivated to improve their physical activity levels, but often fail to act upon their intention. Interventions fostering volitional strategies, such as action planning, coping planning, and self-efficacy beliefs, can help to translate intentions into behavior. This study examines the effectiveness and the mechanisms of a combined planning and self-efficacy intervention to promote physical activity among motivated individuals. Participants (N = 883) were randomly assigned to the intervention or to a waiting-list control condition. Multivariate analysis of variance revealed that the intervention resulted in significantly more physical activity, higher levels of action planning, coping planning, and volitional self-efficacy beliefs (p < 0.01). In addition, multiple mediation analysis showed that action planning, coping planning, and volitional self-efficacy mediate between the intervention and physical activity. The study shows that the intervention successfully fostered physical activity and unfolds the underlying self-regulatory mechanisms of the intervention's effectiveness.     

A review of common sleep disorders

What should clinicians know about sleep disorders? This article briefly introduces the reader to sleep medicine and succinctly reviews common sleep disorders. First, the authors describe the diagnostic tools unique to sleep medicine: the over-night polysomnogram and the multiple sleep latency test. Next, the authors review essential features of a subset of the sleep, described in the International Classification of Sleep Disorders-Revised, that sleep disorder specialists commonly evaluate, diagnose, and treat. The disorders reviewed include the intrinsic and circadian rhythm subsets of the dyssomnias group and the parasomnia group of sleep disorders. The authors identify the core signs and symptoms, polysomnogram findings, multiple sleep latency test findings, and treatment of these disorders.     

Some Practical Implications of Integrating Narrative and Humanistic/Existential Approaches to Psychotherapy

Although the humanistic/existential and the narrative approaches to psychotherapy are clearly distinct perspectives with some marked differences at the level of metatheory, they also show very important similarities in their conceptualization of the human condition and the processes involved in living adaptively (Richert, 1999). These similarities make these two approaches reasonable candidates for integration. The present paper examines five specific points of integration at the level of strategy and techniques (Neimeyer, 1993b): Interplay of experiential meanings and narrative structure in developing client meaning, use of existential themes in client narratives, deconstruction as a means of dealing with existential guilt, contextualization of wishes as a means of mobilizing will, and reflexivity as a way of developing the I–Thou relationship. A brief theoretical rationale is offered for each of these points of integration, and each is illustrated with clinical examples.     

Observers' proficiency at identifying pretense acts based on behavioral cues

Discriminating what is pretense from what is real is a fundamental problem in development. Research has addressed the proficiency with which adults and children discriminate between play fighting and real fighting, and yet none (to our knowledge) has investigated discrimination of other kinds of pretense and real acts. In addition, little is known about what aspects of pretender behavior (as opposed to pretend content) might cue pretense interpretations. In two experiments, 8-20 s clips showing pretense and real snack behaviors were presented to adult and child participants. All participants distinguished between pretense and real behaviors at better than chance level. Furthermore, certain features (specific looking patterns and mistimed behaviors) were most prominent in the videotapes that were most often correctly identified. This provides empirical support for the suggestion that these cues, as opposed to more commonly cited cues, like smiles, might serve as important indicators of pretense for children and adults.
