SUMMARY:Optimising eyewitness testimony by matching witness chronotype and

DESCRIPTION:Circadian rhythm influences cognitive performance: some people
  think best in the mornings (morning chronotypes)\, others at night (eveni
 ng chronotypes). Furthermore there are large age differences in the distri
 bution of morning and evening chronotypes in the population. Young people 
 (aged 18-23 years) are predominantly evening or neutral types\, while olde
 r adults are predominantly morning types\, and fewer than 3% are evening t
 ypes. (Yoon\, May\, & Hasher\, 2000). Within the cognitive aging literatur
 e the existence of a “synchrony effect” is discussed\, meaning that pe
 rsons tested at their preferred time of time (e.g. morning persons tested 
 in the morning) perform better in a range of cognitive tasks than those te
 sted not at their optimal time of day (e.g. morning persons tested in the 
 evening). However\, this effect has never been tested within the field of 
 eyewitness psychology. \n\nThis talk will present the results of two exper
 iments examining the effect of circadian rhythm and of matching chronotype
  and interviewing time on two eyewitness tasks for two age groups (younger
  adults aged under 30 years and older adults aged 60 and above). The studi
 ed variables were completeness and accuracy of eyewitness memory in an int
 erview\, and the accuracy of person identification decisions. The results 
 have implications for the creation of practical interventions in forensic 
 interviewing practice\, and for the academic study of age differences in e
 yewitness psychology.
