Infant touching behaviour during mother–infant face‐to‐face interactions

The study of infant communication during mother–infant interactions has largely focused on infants' distal behaviours, while neglecting their more proximal behaviours, such as touch. Yet, touch is an important modality through which infants and mothers communicate; it is also a vital means through which infants self‐regulate and explore their surroundings. The present study was designed to investigate the touching behaviours of 44, 51/2‐month‐old, healthy, full‐term infants during face‐to‐face mother–infant interactions. A still‐face (SF) procedure was used in order to examine differences in the types and locations of infant touch across normal and perturbed interaction periods, when mothers exhibit changes in their emotional availability. Results revealed that infant touch varied with changes in maternal availability. During the SF period, when mothers were unavailable, infants used more active, soothing, and reactive tactile behaviours (stroke, finger, pat, and pull), and they spent more time touching themselves. In contrast, infants used mostly passive touch (static) during the Normal periods, when their mothers were available. They also spent a significant portion of time touching their mothers. The variations in infant touch across periods suggest that infants communicate their affective states through touch. The findings also support the regulatory and exploratory roles of infant touch, especially during periods of maternal unavailability. Copyright © 2007 John Wiley & Sons, Ltd.     

Environmental Correlates of Gambling Behavior in Urban Adolescents

The present study considered the relation between adolescent gambling behavior and the perceived environment, the component of Jessor and Jessor’s (1977) Problem Behavior Theory that assesses the ways that adolescents perceive the attitudes and behaviors of parents and peers. The predominantly African-American sample included 188 sophomores from two urban public high schools. Using the South Oaks Gambling Screen-Revised for Adolescents to assess gambling risk, rates of both at-risk (20.7%) and problem (12.8%) gambling were found to be high. Boys displayed more gambling problems than did girls. The perceived environment accounted for significant variance in gambling problems and frequency, with proximal components displaying stronger relationships than distal components. Perceiving parent gambling and friend models for problem behavior were positively correlated with gambling problems, and friend models were positively related to gambling frequency. Among girls, family support was positively related to gambling problems. Among boys, this relation was negative. The authors Emerson M. Wickwire, Jr. James P. Whelan, and Andrew W. Meyers are members of The Institute for Gambling Education and Research, Department of Psychology, The University of Memphis, Memphis, TN. The primary research interest of this group is the prevention and treatment of gambling related problems. David M. Murray, Ph.D., is the Chair of the Division of Epidemiology at the School of Public Health, The Ohio State University, Columbus, OH.     

Environmental Contributions to Adolescent Delinquency: A Fresh Look at the Shared Environment

Few genetically-informative studies have attempted to explicitly identify the shared environmental (i.e., those environmental influences that contribute to sibling similarity) factors now known to contribute to adolescent delinquency. The current study therefore examined whether the parent-child relationship served as one source of these shared environmental influences. Participants were 610 adoptive and biological families from the Sibling Interaction and Behavior Study (SIBS). Parents and adolescents reported on their parent-child conflict and parental involvement with child, and adolescents reported on their own delinquent behaviors. We employed structural equation modeling and supplementary multilevel modeling, finding consistent evidence that the association between delinquency and the parent-child relationship is at least partially shared environmental in origin. Such findings provide an important extension of previous twin studies, as they suggest that passive genotype-environment correlations do not explain earlier findings of shared environmental influences on this association.     

Patterns of Natural Language Use: Disclosure, Personality, and Social Integration

When people write about their deepest thoughts and feelings about an emotionally significant event, numerous benefits in many domains (e.g., health, achievement, and well-being) result. As one step in understanding how writing achieves these effects, we have developed a computer program that provides a "fingerprint" of the words people use in writing or in natural settings. Analyses of text samples indicate that particular patterns of word use predict health and also reflect personality styles. We have also discovered that language use in the laboratory writing paradigm is associated with changes in social interactions and language use in the real world. The implications for using computer-based text analysis programs in the development of psychological theory are discussed.     

胼胝体调节大脑两半球相互作用的机制

胼胝体是哺乳动物脑内最大的白质结构,不仅可以在大脑两半球间传递信息,也能调节半球间的相互作用,“抑制模型”和“兴奋模型”是当前解释胼胝体调节机制的主要模型.前者假设,胼胝体对半球间的信息传递起抑制作用,表现为优势半球的功能增强,非优势半球的活动抑制,因而可以提高半球加工的独立性和功能不对称性;后者则认为,胼胝体对半球间信息传递起促进作用,导致两半球同时性活动,并增强其功能连接性,因而可以降低半球的功能不对称性,有利于半球间的信息共享与功能整合.近期的研究显示,胼胝体并不是一个结构与功能的单一体,而是包含了在空间与时间上既分离又互动的多通道信息加工复合体.抑制与兴奋信息可以通过胼胝体的不同空间通道以不同的速度在半球间进行传递,并受到任务计算类型与复杂性的调节,因此,胼胝体的抑制与兴奋的协同可以调节两半球的动态相互作用.

PROMOTING RECIPROCAL INTERACTIONS VIA PEER INCIDENTAL TEACHING

This study evaluated peer incidental teaching as a strategy for increasing reciprocal peer interactions by children with autism. Three typical preschoolers were trained as peer tutors for 3 young children with autism. During a classroom free-play session, peer tutors used incidental teaching to obtain verbal labels of preferred toys by children with autism. A multiple baseline across the 3 target children showed replicated positive effects of the intervention. Adult supervision and assistance were then faded systematically, with resulting maintenance of increased reciprocal interactions. Multiple measures of the extent and limits of generalization suggested that 1 child increased interactions in free-play periods throughout the day, but none of the children showed increases at lunch. Teacher and peer ratings supported the social validity of positive findings.     

Effects of cocaine and alcohol, alone and in combination, on human learning and performance.

The acute effects of cocaine hydrochloride (4 to 96 mg/70 kg) and alcohol (0 to 1.0 g/kg), administered alone and in combination, were assessed in two experiments with human volunteers responding under a multiple schedule of repeated acquisition and performance of response chains. Subjects were intermittent users of cocaine and regular drinkers who were not cocaine or alcohol dependent. Alcohol was mixed with orange juice and ingested in six drinks within 30 min; cocaine was administered intranasally 45 min after completion of drinking. In each component of the multiple schedule, subjects completed response sequences using three keys of a numeric keypad. In the acquisition component, a new sequence was learned each session. In the performance component, the response sequence always remained the same. Results were consistent in both experiments, despite variations in the order in which the drugs were tested alone and in combination. Alcohol administered alone increased overall percentage of errors and decreased rates of responding in the acquisition component, whereas responding in the performance component generally was unaffected. Cocaine administered alone decreased rates of responding but did not affect accuracy of responding in the acquisition component, and enhanced accuracy of responding without affecting rates of responding in the performance component. The combined doses of cocaine and alcohol attenuated the effects observed with alcohol and cocaine alone. These results suggest that, under the conditions investigated in this study, (a) alcohol produces greater behavioral disruption than cocaine or cocaine-alcohol combinations, (b) cocaine and alcohol each attenuate effects of the other, and (c) such attenuation is most pronounced for cocaine attenuating the disruptive effects of alcohol.     

Physiological,affective, and behavioral responses to interpersonal conflict among males from families with different levels of cohesion and adaptability

To examine the relation between characteristics of a person's family of origin and cardiovascular, behavioral, cognitive, and affective response to interpersonal conflict, responses of 15 young males from families rated as extreme (EXT) on scales of cohesion (enmeshed or disengaged) or adaptability (chaotic or rigid) were compared to those of 25 young males from families rated as balanced (BAL) on measures of cohesion and adaptability. Subjects participated in two interpersonal role-play conflict situations, one with a male confederate and the other with a female confederate. Measures of heart rate (HR), blood pressure, and indices of both positive and negative verbal and nonverbal behaviors were obtained during each scenario and self-reported measures of positive and negative cognitive self-statements and affective response were obtained following each conflict scene. Results showed that, in contrast to BAL males, EXT males exhibited more negative verbal and nonverbal behavior, less positive nonverbal behavior, higher ratings of state anxiousness during conflict, and higher HR responses during the interaction with the male confederate than the female confederate. These findings suggest that exposure to a family environment with extreme levels of cohesion and adaptability impacts how an individual responds to interpersonal conflict in young adulthood.     

Temenos Lost: Reflections on Moving

This article examines some clinical dilemmas engendered by moving. At such times, certain patients (or the analysts themselves) may lose their sense of containment that the therapeutic space has provided. When such a disruption threatens the course of treatment, this changed condition may be archetypaily termed 'temenos lost'. Consideration of this condition has led the author to reconceptualize healing as composed of two distinct components: the healing relationship and the healing space. Together, these components define the healing archetype. Using two historical examples, the King's Evil in Tudor England and healing pilgrimages in Israel, he shows how each component may indeed operate independently. More often, however, they function together. Using an extended published case (Volkan 1984), the author examines various aspects of how patients and analysts cope with 'temenos lost'. He emphasizes the importance of the emotional atmosphere in the physical setting, anticipatory anxiety of losing the temenos, and the basic anxiety that the move will damage the analysis. The importance of the rite of re-entry for the patient is emphasized as a symbolic way of resolving 'temenos loss' that permits a healing move into a 'temenos regained'.
