Experimental analysis of proximity as a social stimulus: Increasing on‐task behavior of an adolescent with autism

Experimental analysis of social stimuli has typically been restricted to the presence or absence of verbal attention. In the present study, an ABAB design was used to assess the influence of proximity as a social stimulus. Close and distant proximity of a familiar adult was systematically manipulated to evaluate the effect of proximity on the on‐task behavior of a 15‐year‐old male with autism. Baseline, experimental analysis, and intervention phases were conducted within a self‐contained classroom. Pronounced effects of distant educator proximity to the participant were evident during both the experimental analysis and intervention, with increased on‐task behavior occurring in the distant condition. Future recommendations for the investigation of proximity as a relevant social stimulus are forwarded. © 2005 Wiley Periodicals, Inc. Psychol Schs 42: 189–196, 2005.     

The analysis and treatment of child abuse by behavioural psychotherapy

The results from use of behaviour therapy with child abuse cases is very encouraging. Data has been presented to show the approach both economical and rewarding. Our experience suggests that selected social workers may be able to learn to use the approach with a relatively short period of training.     

Long-term trends in home advantage in professional team sports in North America and England (1876-2003)

Home advantage is quantitatively defined and calculated for each season since the start of the main professional sports in North America and England. Over 400,000 games are analysed. The leagues represented are the National League (1876-2002) and American League (1901-2002) for baseball, the National Hockey League (1917-2003) for ice hockey, the National Football League (1933-2002) for American football, the National Basketball Association (1946-2003) for basketball, and the four levels of professional football, formerly called the Football League, in England (1888-2003). Problems caused by unbalanced playing schedules are considered. The results are presented graphically to show long-term trends and sudden changes. The highest levels of home advantage for all sports were in their early years of existence. Home advantage in ice hockey, basketball and football in England has declined over the last two decades. In baseball there has been very little change over the last 100 years, with home advantage consistently lower than in other sports. There was a large drop in home advantage in football in England following the 7-year suspension of the league during the Second World War. The trends and changes provide some evidence that travel and familiarity contribute to home advantage, but little in support of crowd effects.
