Sources of acute stress, cognitive appraisal, and coping strategies among highly skilled Mexican and U.S. competitive tennis players

The purpose of the present investigation was to identify sources of acute stress, cognitive appraisal (i.e., perceived controllability), and the use of coping strategies as a function of culture among highly skilled tennis players from Mexico and the United States. Participants were 112 competitive tennis players, 54 of whom were from Mexico (44 boys, 10 girls), and 58 of whom were from the United States (30 boys, 28 girls). A qualitative analysis indicated that the most common sources of acute stress in tennis include "receiving negative comments from coaches and relatives" and "opponent cheating." The authors adapted the COPE Instrument (C. Carver, M. F. Scheier, & J. K. Weintraub, 1989) to ascertain the athletes' use of coping strategies. Regression analysis assessed the extent to which culture predicted the athletes' perceived controllability of the stressors and their use of coping strategies. The results indicated that culture significantly predicted both perceived controllability and the use of coping strategies. The authors discussed implications for the role of culture in predicting cognitive appraisal and coping in sport.     

Conditions favoring retroactive interference between antecedent events (cue competition) and between subsequent events (outcome competition)

Retrieval of a target association (A-B) is often impaired if training of a similar association is interpolated between target training and testing; this is known asretroactive interference. Two experiments, in which rats were used as subjects in a sensory preconditioning preparation, studied the associative nature of retroactive interference between antecedent events (i.e., A and C in the A-B, C-B paradigm) and between subsequent events (i.e., B and C in the A-B, A-C paradigm). With the present preparation, retroactive interference was equally strong between antecedent events and between subsequent events. Moreover, interference occurred only if (1) an association was trained in the interpolated phase and (2) the target and interpolated associations had a common element in a common temporal location.     

Predictors of Externalizing Behavior Problems in Early Elementary-Aged Children: The Role of Family and Home Environments

As children enter elementary school they display behavioral orientations that reveal potential developmental trajectories. Developmental transitions offer unique opportunities for examining developmental pathways and the factors that influence emerging pathways. The primary goal of this investigation was to examine characteristics of family and home contexts in predicting externalizing behavior problems among children transitioning into elementary school. Dimensions of the family and home environments of maltreated and nonmaltreated children (N = 177) were examined and used to predict externalizing behavior problems. Maltreatment was assessed using case file information, characteristics of the family and home environment were rated by interviewers, and externalizing behavior was assessed by mother's ratings on the Child Behavior Checklist. Relative to nonmaltreated children, the family environments of physically abused children were characterized by higher levels of negative social interactions. Also, in comparison to nonmaltreated children, the home environments of children who experienced neglect were characterized as less organized and clean. Hierarchical regression analyses revealed that physical abuse was the strongest predictor of externalizing behavior. After controlling for the contribution of physical abuse, mother's negative behavior toward the focal child, aggression between siblings, and the lack of an organized and clean home were each predictive of externalizing behavior.     

Nu-Way Snaps and Snap Leads: an Important Connection in the History of Behavior Analysis

Beginning in the early 1950s, the snap lead became an integral and ubiquitous component of the programming of electromechanical modules used in behavioral experiments. It was composed of a Nu-Way snap connector on either end of a colored electrical wire. Snap leads were used to connect the modules to one another, thereby creating the programs that controlled contingencies, arranged reinforcers, and recorded behavior in laboratory experiments. These snap leads populated operant conditioning laboratories from their inception until the turn of the twenty-first century. They allowed quick and flexible programming because of the ease with which they could be connected, stacked, and removed. Thus, the snap lead was integral to the research activity that constituted the experimental analysis of behavior for more than five decades. This review traces the history of the snap lead from the origins of the snap connector in Birmingham, England, in the late eighteenth century, through the use of snaps connected to wires during the Second World War, to its adoption in operant laboratories, and finally to its demise in the digital age.
