Because of its reconstructive nature, autobiographical memory (AM) is subject to a range of distortions. One distortion involves the erroneous incorporation of features from one episodic memory into another, forming what are known as memory conjunction errors. Healthy aging has been associated with an enhanced susceptibility to conjunction errors for laboratory stimuli, yet it is unclear whether these findings translate to the autobiographical domain. We investigated the impact of aging on vulnerability to AM conjunction errors, and explored potential cognitive processes underlying the formation of these errors. An imagination recombination paradigm was used to elicit AM conjunction errors in young and older adults. Participants also completed a battery of neuropsychological tests targeting relational memory and inhibition ability. Consistent with findings using laboratory stimuli, older adults were more susceptible to AM conjunction errors than younger adults. However, older adults were not differentially vulnerable to the inflating effects of imagination. Individual variation in AM conjunction error vulnerability was attributable to inhibitory capacity. An inability to suppress the cumulative familiarity of individual AM details appears to contribute to the heightened formation of AM conjunction errors with age. (PsycINFO Database Record

Objective: Dental caries is one of the most common preventable diseases among Indigenous children. The study aimed to estimate the efficacy of an Early Childhood Caries (ECC) intervention among Aboriginal Australian children over 9 years, and to explore potential risk factors associated with dental caries among Indigenous Australian children.
Methods: Data were from a randomized controlled trial conducted in South Australia, Australia.

We become increasingly susceptible to various false memories as we age. Recent work has shown that in younger adults, associations between false memories in different paradigms are weak or non-existent. However, it is unknown whether the relationship between false memories changes for older adults.

Utilizing renewable resources to produce epoxides as an alternative to petroleum-based sources is a growing trend. In this regard, several vegetable oils can serve as suitable alternatives. This study investigated the epoxidation of corn oil using sulfuric acid as a catalyst.

Three studies evaluated Tversky and Kahneman's (1983) proposal that the conjunction fallacy (judging the probability of a conjunction of two events to be higher than that of its component events) arises due to the representativeness heuristic. Since such heuristic thinking is not innate and depends upon the individual learning the extent to which situations are likely to occur, our evaluation adopted a developmental approach. Study 1 (N = 82 adults; N = 71 4- to 5-year-olds), Study 2 (N = 130 adults; N = 148 4- to 11-year-olds), and Study 3 (N = 76 adults) assessed objective probability judgements by asking participants to determine whether a single player or a two-player team would win based on assigned poker chip (adults) or building block (children) distributions.

Accurate quantification of bone mineral, organic, and water phases is critical for evaluating bone quality, assessing fracture risk, and diagnosing skeletal diseases. Dual-energy computed tomography (DECT) holds promise for decomposing these phases but fundamentally relies on precise linear attenuation coefficients (LACs) for each phase. Existing surrogate-based imaging methods-typically assuming fixed phase attenuation coefficients-fail to reflect the compositional heterogeneity of native bone, leading to systematic errors in decomposition.
