There are documented deficits in older adults' abilities to bind numerical information to other types of information, perhaps due to the arbitrariness and specificity of numbers. Although some studies have found that memory for associative details is more accurate for emotionally salient information than for emotionally neutral information, other research has failed to find this benefit. We investigated whether older adults' associative memory deficit for numerical information may be reduced when information is encountered in an emotionally salient context. We presented younger and older adults with numerical information in a sentence that was emotionally positive, negative, or neutral and later asked them to recall the numbers when given their corresponding context. Although younger adults recalled more information than older adults, both groups of participants recalled more numbers in emotionally valenced as compared with emotionally neutral contexts, with the most accurate memory for numbers in the highly arousing negative context. Both groups of participants also rated the negative information as more important and easier to remember. These results provide evidence that emotion-enhanced binding is consistent between younger and older adults in some contexts and that memory for specific and arbitrary numerical information may be more accurate in an emotionally salient as compared with emotionally neutral context.
