One crucial activity in software product line (SPL) testing is the detection of erroneous artifact interactions when combined for a variant. This detection is similar to the retest test-case selection problem in regression testing, where change impact analysis is applied to reason about changed dependencies to be retested. In this paper, we propose automated change impact analysis based on incr...

Regression testing is an important but expensive software maintenance activity aimed at providing con-dence in modiied software. Selective retest methods reduce the cost of regression testing by selecting tests for a modiied program from a previously existing test suite. Many researchers have addressed the selective retest problem for procedural-language software, but few have addressed the pro...

This study assessed plasticity of inhibition in older adults through examining retest practice effects in a six-session training paradigm using the Stroop task and the training-induced transfer effects to a range of cognitive measures. Fifty-six older adults (aged 60-84 years, mean = 71.05, standard deviation = 6.17) participated in this study. They were evenly assigned to one of four groups: s...

The research work reported in this paper addresses the question whether retest practice changes the speed-ability relationship. In three successive test sessions several cognitive tests of attention, memory and working memory were administered: Attention Switching Task, Continuous Attention Task, Memory Scanning Task, Letter Comparison Task, and Maintenance Summation Task. Retest practice led t...

Without visual stimulation, the eye tends to assume an individually-determined intermediate state of accommodation (the "dark focus"). The present study examined the stability of these individual dark focus values over time. Two sets of measurements were obtained with a laser-Badal optometer for each of 39 college-age subjects. For 19 subjects the second test occurred during the same experiment...

Although within-person comparisons allow direct assessments of change, some of the observed change may reflect effects associated with prior test experience rather than the processes of primary interest. One method that might allow retest effects to be distinguished from other influences of change involves comparing the pattern of results in a longitudinal study with those in a study with a ver...
