Contextual influences on baseball ball-strike decisions in umpires, players, and controls

Baseball umpires, players, and control participants with no baseball experience were asked to call balls and strikes for video clips. In a basic judgement task, umpires and players were significantly better at calling pitches than controls. In a direct information task, borderline pitches were presented following clips of definite balls and definite strikes. Participants called target pitches closer to the strike end of the scale when viewed after definite balls than when they followed definite strikes. Similarly, when borderline pitches were shown in different pitch counts, participants called pitches more towards the strike end of the scale when there were three balls in the count (3-0, 3-2). These findings indicate that the standard for evaluation changes based on the context in which stimuli are processed. Moreover, the strength of the contextual factors is illustrated in that the effects were shown in observers with and without experience in the task. Overall, however, umpires had a greater tendency to call strikes, indicating that they may use a norm of "hastening the game".     

Reconceptualizing the role of habit: A new model of television audience activity

This paper explores the role played by habit in shaping audience behavior through an analysis of Nielsen audience data. Through the use of a structural equation model, comparisons, are made between individuals’ weekday and weekend viewing patterns to determine if similarities persist despite the structural and programmatic differences in those time periods. Results indicate that habit plays a significant role in viewing behavior.     

Little pitchers use their big ears: preschoolers solve problems by listening to others ask questions

Children ask questions and learn from the responses they receive; however, little is known about how children learn from listening to others ask questions. Five experiments examined preschoolers' (N = 179) ability to solve simple problems using information gathered from listening to question-and-answer exchanges between 2 parties present in the same room. Overall, the ability to efficiently use information gathered from overheard exchanges improved between ages 3 and 5. Critically, however, across ages children solved the majority of problems correctly, suggesting preschoolers are capable of learning from others' questions. Moreover, children learned from others' questions without explicit instruction and when engaged in another activity. Implications for the development of problem-solving skills are discussed.
