Effects of genetic vestibular defects on behavior related to spatial orientation and emotionality.

A large battery of behavioral tests was administered to normal mice and to mice with varying degrees of otoconial agenesis due to genes affecting vestibular development. Many significant differences were found, but a factor analysis revealed that the variance on the 11 best tests could be accounted for in terms of two underlying variables. Factor I, the more important of the two, was associated with activity, habituation, and spontaneous alternation. Factor II appeared to represent a fear of new stimuli or situations. In both cases factor scores were highly related to the degree of otoconial deficiency. One subgroup of mice with severe otoconial agenesis displayed hyperactivity and a total absence of either habituation or spontaneous alternation. In these animals, brain and body development were stunted, and the reactions to amphetamine and physostigmine were opposite to those seen in normal mice. The results support the idea that the static organs contribute importantly to spatial orientation and suggest that early-onset vestibular defects can result in profound alterations of emotionality.     

Zur Analyse des Bumerang-Effektes

Zusammenfassung In zwei Experimenten wurde mit Hilfe unterschiedlicher sozialer Attitüden und Werthaltungen jeweils die Hypothese geprüft, daß sich Einstellungen nach einstellungskonträrer Agitation in Richtung dieser Agitation oder aber nicht und in Gegenrichtung zur Agitation ändern, je nachdem ob sie weniger oder mehr in allgemeineren Werthaltungen verankert sind. Im Rahmen einer um die Konzeption der Verankerung erweiterten Theorie der kognitiven Dissonanz können damit besser als bisher sogenannte Bumerang-Effekte bei Änderungen von Attitüden erklärt werden.

Summary In two experiments we tested the following hypothesis concerning social attitudes and value orientations: Attitudes will be changed after counter-attitudinal agitation in the direction of this agitation or in opposite direction depending on their degree of being anchored in general value orientations. With the theory of cognitive dissonance, supplemented by the conception of anchoring, we are now able to explain better than before the so-called boomerang-effects which appear with attitude changes.

     

A Systematic Review of Sleep Associations in Parents and Children

This systematic review aimed to examine sleep associations in a) typically developing children and their parents, and b) children with neurodevelopmental disorders and their parents. Literature search was conducted on PubMed, PsycINFO, EMBASE and Scopus databases for articles examining sleep associations between parents and children. Thirty studies were included in the final review. Based on the first aim, sleep associations between parents and typically developing children were observed for sleep quality, sleep duration and sleep efficiency. However, evidence for associations between sleepiness levels in parents and children and sleep schedules related to bedtime or waketime was limited. Based on the second aim, children with neurodevelopmental disorders and their parents reported greater sleep disturbances in comparison to typically developing children and their parents. The review concluded that sleep in parents and children is interrelated across a number of sleep parameters. It also revealed some preliminary evidence on bidirectionality in parent-child sleep, which warrants further examination. The review highlights the need to examine the mediating role of environmental factors on the interactions between parent-child sleep. Rigorous, longitudinal designs should be employed to explore the pathways through which parents may impact their children’s sleep and functioning and vice-versa.

     

Developmental kinesics: How children acquire communicative and non-communicative nonverbal behavior

This article is a position paper concerning the major issues in the study of children's acquistion of nonverbal behavior. In linguistic theory non-verbal behavior may be considered irrelevant, it may be condsidered the precursor of verbal language, or it may be viewed as an integral part of human communication which is verbal and nonverbal. The author opts for the latter theory. Concerning the relationship between what is innate and what is learned, the paper discusses that nonverbal expression is innate, but culture determines its forms and its uses. The paper then presents a brief history of Developmental Kinesics, explaining its technical difficulties and its methodological complexities. It proceeds by documenting the function of maternal nonverbal behavior towards the neonate. Finally, the paper treats the levels of analysis. A distinction is drawn between communicative and non-communicative nonverbal behavior. Its affective, emotional function relates to ego state; its regulatory function governs face-to-face interaction; and its referential, informative function pertains to the message proper. The child also acquires the non-interactional aspects of body movements which distinguish different peoples. Expression and perception must be studied separately; and finally, nonverbal behavior has to be correlated with verbal behavior and particular attention has to be focused on the double bind.     

The Infant mental health specialist in newborn pediatric rounds: A systems approach

This article describes a special program wherein infant mental health specialists participate in hospital rounds with pediatric residents. The purpose of the program is described in terms of medical awareness of psycho-social needs of the family and improved clinical services. Examples are given of the way in which “rounding” contributes to the meeting of infants' and families' medical and psychological needs. Note is made of the multilevel impact of this collaboration.
