Articulatory constraints on interpersonal postural coordination

Cooperative conversation has been shown to foster interpersonal postural coordination. The authors investigated whether such coordination is mediated by the influence of articulation on postural sway. In Experiment 1, talkers produced words in synchrony or in alternation, as the authors varied speaking rate and word similarity. Greater shared postural activity was found for the faster speaking rate. In Experiment 2, the authors demonstrated that shared postural activity also increases when individuals speak the same words or speak words that have similar stress patterns. However, this increase in shared postural activity is present only when participants' data are compared with those of their partner, who was present during the task, but not when compared with the data of a member of a different pair speaking the same word sequences as those of the original partner. The authors' findings suggest that interpersonal postural coordination observed during conversation is mediated by convergent speaking patterns.     

Rocking together: dynamics of intentional and unintentional interpersonal coordination

The current study investigated the interpersonal coordination that occurred between two people when sitting side-by-side in rocking chairs. In two experiments participant pairs rocked in chairs that had the same or different natural periods. By instructing pairs to coordinate their movements inphase or antiphase, Experiment 1 investigated whether the stable patterns of intentional interpersonal coordination were consistent with the dynamics of within person interlimb coordination. By instructing the participants to rock at their own preferred tempo, Experiment 2 investigated whether the rocking chair movements of visually coupled individuals would become unintentionally coordinated. The degree to which the participants fixated on the movements of their co-actor was also manipulated to examine whether visual focus modulates the strength of interpersonal coordination. As expected, the patterns of coordination observed in both experiments demonstrated that the intentional and unintentional interpersonal coordination of rocking chair movements is constrained by the self-organizing dynamics of a coupled oscillator system. The results of the visual focus manipulations indicate that the stability of a visual interpersonal coupling is mediated by attention and the degree to which an individual is able to detect information about a co-actor's movements.     

The effect of the NMDA receptor antagonist MK-801 on the acquisition and extinction of learned fear in the developing rat

Recent findings reveal qualitative developmental differences in extinction of learned fear. The present study explored potential developmental differences in the role of NMDA in acquisition and extinction. Rats were injected with MK-801 prior to fear conditioning or extinction training. Acquisition was found to be NMDA dependent in both age groups, whereas extinction was found to be NMDA dependent in 23-day-old rats, but NMDA independent in 16-day-old rats. These results illustrate another fundamental developmental difference in extinction as well as a dissociation in the role of NMDA in the acquisition and extinction of fear early in development.     

Parametrically Dissociating Speech and Nonspeech Perception in the Brain Using fMRI

Candidate brain regions constituting a neural network for preattentive phonetic perception were identified with fMRI and multivariate multiple regression of imaging data. Stimuli contrasted along speech/nonspeech, acoustic, or phonetic complexity (three levels each) and natural/synthetic dimensions. Seven distributed brain regions' activity correlated with speech and speech complexity dimensions, including five left-sided foci [posterior superior temporal gyrus (STG), angular gyrus, ventral occipitotemporal cortex, inferior/posterior supramarginal gyrus, and middle frontal gyrus (MFG)] and two right-sided foci (posterior STG and anterior insula). Only the left MFG discriminated natural and synthetic speech. The data also supported a parallel rather than serial model of auditory speech and nonspeech perception.     

"Brainwashing" Theories in European Parliamentary and Administrative Reports on "Cults" and "Sects"

This study examines the recent rash of official reports done by governmental agencies in Western Europe to guide policy development in those societies. Particular attention is given to reports in France, Belgium, Switzerland, Germany, Sweden, and Italy, and to the changes in such reports that have occurred, perhaps because of the influence of scholarly critiques offered for some of the earlier reports. The reports are divided into "Type I" and "Type II" reports, with the former being thorough-going in their anti-cult orientation, and the latter reports being more moderate in tone, with some attention paid to scholarship on new religions. However, the major thesis of the study is supported, as an examination of both types of reports reveals that they incorporate "brainwashing" and "mind control" imagery imported from the United States, even though such theories have been largely discounted within the United States. Use of such theories leads directly to some questionable policy recommendations, as demonstrated in the reports. Reasons for the spread of "brainwashing" ideas to Europe are discussed.     

Can pictures promote the acquisition of sight‐word reading? An evaluation of two potential instructional strategies

Sight‐word instruction can be a useful supplement to phonics‐based methods under some circumstances. Nonetheless, few studies have evaluated the conditions under which pictures may be used successfully to teach sight‐word reading. In this study, we extended prior research by examining two potential strategies for reducing the effects of overshadowing when using picture prompts. Five children with developmental disabilities and two typically developing children participated. In the first experiment, the therapist embedded sight words within pictures but gradually faded in the pictures as needed using a least‐to‐most prompting hierarchy. In the second experiment, the therapist embedded text‐to‐picture matching within the sight‐word reading sessions. Results suggested that these strategies reduced the interference typically observed with picture prompts and enhanced performance during teaching sessions for the majority of participants. Text‐to‐picture matching also accelerated mastery of the sight words relative to a condition under which the therapist presented text without pictures.     

Noncontingent reinforcement without extinction plus differential reinforcement of alternative behavior during treatment of problem behavior

The effects of noncontingent reinforcement (NCR) without extinction during treatment of problem behavior maintained by social positive reinforcement were evaluated for five individuals diagnosed with autism spectrum disorder. A continuous NCR schedule was gradually thinned to a fixed‐time 5‐min schedule. If problem behavior increased during NCR schedule thinning, a continuous NCR schedule was reinstated and NCR schedule thinning was repeated with differential reinforcement of alternative behavior (DRA) included. Results showed an immediate decrease in all participants’ problem behavior during continuous NCR, and problem behavior maintained at low levels during NCR schedule thinning for three participants. Problem behavior increased and maintained at higher rates during NCR schedule thinning for two other participants; however, the addition of DRA to the intervention resulted in decreased problem behavior and increased mands.     

Linking Family-of-Origin Experiences and Perpetration of Sexual Coercion: College Males’ Sense of Entitlement

Sexual coercion on college campuses has become of major concern in recent decades. In recent years, researchers and policy makers have called for greater attention to this topic in order to reduce the sexual violence on college campuses. Recent research has examined the impact of family-of-origin experiences on the perpetration of sexual coercion. The current study examines the association between family-of-origin experiences, such as warmth and hostility between parents, inconsistent parenting, and overparenting during childhood, and the perpetration of sexual coercion among emerging adult males while examining feelings of entitlement as a possible mediator. Data from 326 male undergraduate students were analyzed using structural equation modeling. Results show that warmth and hostility between parents has a significant association with parenting behaviors (i.e., overparenting and inconsistent parenting) and that hostility between parents is associated with the perpetration of sexual coercion by the offspring in young adulthood for males. Also, findings suggest that while overparenting and inconsistent parenting during childhood are not directly associated with the perpetration of sexual coercion during emerging adulthood, they are strongly related to feelings of entitlement, which in turn was found to be associated with the perpetration of sexual coercion for males. These results have important implications for family life education, including relationship and parenting education, and for future research.
