Infant sensitivity to figural coherence in biomechanical motions

Two experiments assessed infant sensitivity to figural coherence in point-light displays moving as if attached to the major joints of a walking person. Experiment 1 tested whether 3- and 5-month-old infants could discriminate between upright and inverted versions of the walker in both moving and static displays. Using an infant-control habituation paradigm, it was found that both ages discriminated the moving but not the static displays. Experiment 2 was designed to clarify whether or not structural invariants were extracted from these displays. The results revealed that (1) moving point-light displays with equivalent motions but different topographic relations were discriminated while (2) static versions were not, and (3) arrays that varied in the amount of motion present in different portions of the display were also not discriminated. These results are interpreted as indicating that young infants are sensitive to figural coherence in displays of biomechanical motion.     

A possible proximity effect on human grip strength

A double-blind experiment with 58 adults tested the hypothesis that proximity to sugar reduces human grip strength. An analysis of variance supported the hypothesis.     

Effects of family therapy for substance abuse: A systematic review of recent research

One of the most serious psychosocial problems worldwide is substance abuse because of its repercussions not only on the physical and psychological health of the abuser but also on their relational functioning. Among the well-established therapeutic approaches for the treatment of substance abuse is family therapy, which, in addition to influencing personal variables, promotes changes in family dynamics. The main objective of this study is to review the scientific literature published from 2010 to the present on the efficacy and effectiveness shown by family-based treatment approaches for substance use problems both in adolescent and adult samples. In addition, the effect on secondary variables such as family functioning and behavioral problems is evaluated. The empirical evidence accumulated in the last decade and reviewed in the present study indicates that the incorporation of family members in the treatment of substance abuse produces benefits by diminishing consumption and improving family functioning. Limitations of this study and of the research reviewed are discussed and directions for future research are provided.     

Dance becomes therapeutic in the mid to late 20th century

The convergence of dance art and therapeutic culture engendered the development of dance-movement therapy in the mid to late 20th century internationally. This article traces the sociopolitical, institutional, and aesthetic influences that coalesced in this process by contrasting histories of dance-movement therapy in Hungary and in the United States. The professionalization dance-movement therapy, through which it established its own theory, practice, and training institutions, occurred first in the United States in the late 1940s. Modern dancers in the United States began to conceptualize their activity as therapeutic, and the dancer as a (secular) healer, a therapist. The influx of therapeutic concepts into the field of dance is viewed as an example of therapeutic discourse permeating various areas of life in the 20th century. The Hungarian case provides a contrasting history of therapeutic culture, one that deviates from the predominant view of the phenomenon as a product of the global spread of Western modernization and the growth of free-market capitalism. Hungarian movement and dance therapy indeed developed independently from its American predecessor. Its history is intimately tied to the sociopolitical context of state-socialist period, particularly to the institutionalization of psychotherapy in public hospitals, and to the adaptation of Western group psychotherapies within the informal setting of the “second public sphere.” The legacy of Michael Balint and the British object-relations school provided its theoretical framework. Its methodology was rooted in postmodern dance. The methodological differences between American dance-movement therapy and the Hungarian method reflects the shift in dance aesthetics that occurred internationally between 1940 and 1980s.

Exploratory study of best friendship dissolution characteristics and psychological difficulties during early adolescence

Few studies have evaluated best friendship dissolutions and especially the circumstances surrounding the dissolutions. In this exploratory study of young adolescents (N = 273, M_age = 11.83 years; 51% boys), we investigate young adolescents' experiences with two types of best friendship dissolution (complete dissolutions, downgrade dissolutions) and two characteristics of such experiences: initiation status (self- versus friend-initiation) and emotional reactions (degree of happiness, anger, sadness, and embarrassment). We also consider whether these characteristics of best friendship dissolutions are related to psychological difficulties (loneliness, depressive symptoms). Results indicated that most young adolescents perceive their friends initiated their recent complete and downgrade dissolutions. When young adolescents did initiate their complete dissolutions, however, they reported less negative (anger) and more positive (happiness) emotional responses. Initiation status was not related to psychological difficulties, but variability in several types of emotional responses (e.g., embarrassment) was related to variability in loneliness and depressive symptoms. Findings underscore the importance of considering not only the type of dissolution, but also the circumstances surrounding dissolutions, during early adolescence.
