General knowledge norms: Updated and expanded from the Nelson and Narens (1980) norms

The Nelson and Narens (Journal of Verbal Learning and Verbal Behavior 19:338–368, 1980) general knowledge norms have been valuable to researchers in many fields. However, much has changed over the 32 years since the 1980 norms. For example, in 1980, most people knew the answer to the question “What is the name of the Lone Ranger’s Indian sidekick?” (answer: Tonto), whereas in 2012, few people know this answer. Thus, we updated the 1980 norms and expanded them by providing new measures. In particular, we report two new metacognitive measures (confidence judgments and peer judgments) and provide a detailed report of commission errors. Each of these measures will be valuable to researchers, and together they are likely to facilitate future research in a number of fields, such as research investigating memory illusions, metamemory processes, and error correction. The presence of substantial generational shifts from 1980 to 2012 necessitates the use of updated norms.     

Examining differences in the levels of false memories in children and adults using child-normed lists

Several previous studies have demonstrated that children, when compared with adults, exhibit both lower levels of veridical memory and fewer intrusions when given semantically associated lists. However, researchers have drawn these conclusions using semantically associated word lists that were normed with adults, which may not lead to the same level of activation or gist generation in children. In the current study, the authors used similar associative word lists normed with children and then evaluated the memory of children and adults using these newly normed lists as well as the typical adult-normed lists. Results indicate that children showed lower true and false memories with both the child-normed and adult-normed lists. Thus, these data suggest that the negative relationship between age and false memories in the Deese-Roediger-McDermott (DRM; J. Deese, 1959; H. L. Roediger & K. B. McDermott, 1995) paradigm is not an artifact of the age group used to construct the lists.     

Associative recognition of face pairs by younger and older adults: the role of familiarity-based processing

Previous research suggested that older adults have a specific impairment in remembering verbal associative information, but it is unclear how elaboration and familiarity might influence this deficit in situations that involve perceptual processing. In the present experiments, younger and older participants studied male-female pairs of faces. Participants were then administered an associative recognition test consisting of previously studied pairs, pairs that contained previously studied items that were not studied together (i.e., conjunction pairs), and entirely new pairs of faces, and participants were instructed to identify pairs that had been presented together at study. Overall, participants were successful at recognizing previously presented pairs but were highly likely to mistakenly endorse conjunction pairs. This pattern was more pronounced for older adults, especially when items were repeated at encoding. Such data suggest that memory for face pairs relies largely on the familiarity of each face and not on a more precise recollection of associative information.

Fitting the child's mind to the world: adaptive norm-based coding of facial identity in 8-year-olds

In adults, facial identity is coded by opponent processes relative to an average face or norm, as evidenced by the face identity aftereffect: adapting to a face biases perception towards the opposite identity, so that a previously neutral face (e.g. the average) resembles the identity of the computationally opposite face. We investigated whether children as young as 8 use adaptive norm-based coding to represent faces, a question of interest because 8-year-olds are less accurate than adults at recognizing faces and do not show the adult neural markers of face expertise. We found comparable face identity aftereffects in 8-year-olds and adults: perception of identity in both groups shifted in the direction predicted by norm-based coding. This finding suggests that, by 8 years of age, the adaptive computational mechanisms used to code facial identity are like those of adults and hence that children's immaturities in face processing arise from another source.     

Minding the Genes: a Multidisciplinary Approach towards Genetic Assessment of Cardiovascular Disease

Genetic assessment for inherited cardiovascular disease (CVD) is increasingly available, due in part to rapid innovations in genetic sequencing technologies. While genetic testing is aimed at reducing uncertainty, it also produces awareness of potential medical conditions and can leave patients feeling uncertain about their risk, especially if there are ambiguous results. This uncertainty can produce psychological distress for patients and their families undergoing the assessment process. Additionally, patients may experience psychological distress related to living with inherited CVD. In order to more effectively manage the psychosocial challenges related to genetic assessment for CVD, a multidisciplinary model expanded to include psychologists and other allied health professionals is outlined. A case study is provided to illustrate how psychological distress can manifest in a patient living with inherited CVD, as well as proposed psychological management of this patient. Finally, a guide for genetic counselors is provided to aid in identifying and managing common psychological reactions to genetic assessment for CVD.     

Grit in adolescence is protective of late-life cognition: non-cognitive factors and cognitive reserve

Various psychological assets have been shown to protect against late-life cognitive impairment by promoting cognitive reserve. While factors such as educational attainment and IQ are well-established contributors to cognitive reserve, noncognitive factors, such as grit, have not been studied in this regard. We examined the contribution of adolescent grit, indexed by high school class rank controlling for IQ, to late-life cognition and its decline among approximately 4000 participants in the Wisconsin Longitudinal Study, a random sample of high school graduates followed from 1957 to 2011. Adolescent grit significantly predicted both immediate and delayed memory at ages 64 and 71, over and above the contribution of IQ. While the relative contributions of IQ and grit to immediate memory were comparable, grit was a stronger predictor of delayed memory. Cognitive reserve has noncognitive, as well as cognitive, components.
