The current experiments investigated the longevity of repetition priming and dissociations between different memory measures. Picture-naming latencies revealed robust repetition priming in four separate studies: Previously named pictures were named faster than new pictures. The magnitude of this naming facilitation was stable across 1 to 6 weeks. The(More)
Two experiments in which participants named pictured objects with difficult or easier names, and a reanalysis and review of published data, reveal that problematic measures used in previous studies obscured the implications of group differences in tip-of-the-tongue (TOT) rates. In Experiment 1, increased age led to more TOTs for difficult but not easy(More)
Autism is a complex neuropsychiatric syndrome with a largely unknown etiology. Inflammation during pregnancy may represent a common pathway by which infections and other insults increase risk for the disorder. Hence, we investigated the association between early gestational C-reactive protein (CRP), an established inflammatory biomarker, prospectively(More)
The tip-of-the-tongue (TOT) experience was compared in younger and older adults, using picture and definition cues to elicit TOTs. Older adults (a) experienced more TOTs, (b) had less target word information available during the TOT, and (c) had more related words (blockers) come to mind during the TOT. There were no age differences in either the speed or(More)
The issue of multiple memory systems is explored. Young and older adults (mean ages = 20 and 71, respectively) named pictures and were tested immediately, 1, 7, or 21 days later. Episodic memory (recognition) for pictures was significantly lower in older relative to young adults and declined systematically across all retention intervals in both age groups.(More)
The present investigation simulated a group conversation in which participants asked (inquirer) and answered (responder) questions, as well as listened to others exchange information. Source (inquirer; responder) identification accuracy was evaluated immediately or after 1 week. Older adults were less adept at source identification, although this difference(More)
In two experiments, we demonstrate that laboratory procedures can evoke false beliefs about autobiographical experience. After shallowly processing photographs ofreal-world locations, participants returned 1 week (Experiments 1 and 2) or 3 weeks (Experiment 2) later to evaluate whether they had actually visited each of a series of new and old pictured(More)
The application of DNA barcoding to anthozoan cnidarians has been hindered by their slow rates of mitochondrial gene evolution and the failure to identify alternative molecular markers that distinguish species reliably. Among octocorals, however, multilocus barcodes can distinguish up to 70 % of morphospecies, thereby facilitating the identification of(More)
The present population-based study examines associations between epilepsy and autism spectrum disorders (ASD). The cohort includes register data of 4,705 children born between 1987 and 2005 and diagnosed as cases of childhood autism, Asperger's syndrome or pervasive developmental disorders--not otherwise specified. Each case was matched to four controls by(More)
