THE EFFECTS OF TRAINING IN CRAWLING ON THE MOTOR AND MENTAL DEVELOPMENT OF INFANTS

LAGERSPETZ, K., NYGÅHD, M. & STRANDVIK, C. The effects of training in crawling on the motor and mental development of infants. Scand. J. Psychol. , 1971 12, 192–197.–Eleven infants under the age of 1 year were trained in creeping for 15 minutes daily for 3 weeks, while 11 children, who served as controls, spent the corresponding times with the experimenters without training. The experimental group learned to creep significantly earlier, and transfer effects on other locomotor development were observed. Even effects on factors other than motor developmental were obtained. A training experiment with a pair of monozygotic twins is also reported.

Children's Representation and Imitation of Events: How Goal Organization Influences 3‐Year‐Old Children's Memory for Action Sequences

Children's imitation of adults plays a prominent role in human cognitive development. However, few studies have investigated how children represent the complex structure of observed actions which underlies their imitation. We integrate theories of action segmentation, memory, and imitation to investigate whether children's event representation is organized according to veridical serial order or a higher level goal structure. Children were randomly assigned to learn novel event sequences either through interactive hands‐on experience (Study 1) or via storybook (Study 2). Results demonstrate that children's representation of observed actions is organized according to higher level goals, even at the cost of representing the veridical temporal ordering of the sequence. We argue that prioritizing goal structure enhances event memory, and that this mental organization is a key mechanism of social‐cognitive development in real‐world, dynamic environments. It supports cultural learning and imitation in ecologically valid settings when social agents are multitasking and not demonstrating one isolated goal at a time.     

Intolerance of Uncertainty and Eating Disorder Symptoms Over the Course of Intensive Treatment

There is a critical need to identify processes that may influence outcome in existing treatments for eating disorders (EDs). Intolerance of uncertainty (IU), which refers to excessive distress regarding uncertain situations, is a well-established feature of anxiety disorders. Emerging work suggests that IU decreases over the course of cognitive-behavioral treatments and may relate to better treatment outcomes. As some literature has suggested IU may functionally maintain ED symptoms, testing whether changes in IU over treatment relate to outcome may result in the identification of novel treatment targets. This study aimed to build upon past work documenting links between IU and ED symptoms by exploring changes in IU over treatment and links between early change in IU (1-month) and discharge symptoms. Participants (N = 274) receiving partial hospitalization treatment completed the Eating Pathology Symptoms Inventory and Intolerance of Uncertainty Scale at admission, 1-month post-admission, and discharge. Results suggested that IU significantly reduced from admission to discharge and that reductions in IU scores from admission to 1-month related to cognitive restraint, dietary restriction, and body image at discharge. However, this pattern did not hold for exercise, binge eating, or purging. Altogether, these results replicate past work supporting IU as a common feature across ED diagnoses and provide initial data suggesting that targeting IU early in treatment may enhance treatment outcomes.     

Acting prosocially reduces retaliation: Effects of prosocial video games on aggressive behavior

Past research has provided abundant evidence that exposure to violent video games increases aggression and aggression‐related variables. In contrast, little is known whether and why video game exposure may also decrease aggressive behavior. In fact, two experiments revealed that playing a prosocial (relative to a neutral) video game reduces aggressive behavior. Mediational analyses showed that differences in both aggressive cognition and aggressive affect underlie the effect of type of video game on aggressive behavior. These findings are in line with assumptions of the General Learning Model and point to the importance of the cognitive and affective routes in predicting how aggressive behavior is affected by exposure to video games.

Assessing different aspects of pretend play within a play setting: Towards a standardized assessment of pretend play in young children

The present study suggests a method with which to assess the interrelations between different types of pretend play. In contrast to standard methods in this area, the various types of pretend play were measured within an interactive play scenario. The pretend play tasks were included in a semi‐structured play sequence and presented to young children between 24 and 30 months of age (N=30). Self‐ and doll‐directed pretence, object substitution, pretence with realistic objects, and self‐initiated pretend play, as well as the understanding that an object had been given two identities was tested. The capacity for dual representation was assessed by asking for the real and pretend identity of an object. Age differences were found in the overall score for elicited pretence but not for all items separately. Individual items also differed in difficulty and thus are of potential use for assessing intraindividual differences in pretend play. Findings are discussed in the context of current theories and methods concerning the development and assessment of pretend play.     

The Persistent Case of Major Depression: An Argument for Long-Term Treatment

According to psychotherapy outcome literature, treatments for major depressive disorder (MDD) yield impressive results. Study after study demonstrates the efficacy of brief, evidence-based interventions for depressed individuals. Nevertheless, MDD continues to exact a devastating toll on modern society. The World Health Organization has identified it as the leading cause of disability worldwide. This reality is surprising given the implications from the academic literature. A historical analysis of MDD treatment suggests that most people with MDD experienced complete remission and enhanced outcomes when long-term, psychodynamically influenced treatments prevailed. An analysis of the system that perpetuates the brief intervention model for MDD, managed care, is discussed. This analysis is followed by a case study that illustrates the harm managed care can do to patients with MDD who are not permitted treatment of longer duration. Implications and recommendations for psychologists to intervene at the micro and macro levels are discussed.
