Advertisers often use specifically chosen wording to convey the effectiveness of their product and we investigated memory accuracy for the scientific claims put forth by product advertisements. Participants were shown a cognitive enhancement product advertisement and were tested on their memory for various details. Critically, we were interested in...

Value-directed remembering refers to the tendency to best remember important information at the expense of less valuable information, and this ability may draw on strategic attentional processes. In six experiments, we investigated the role of attention in value-directed remembering by examining memory for important information under conditions of...

Our memory for common, easily recognizable logos, like the Apple logo, is surprisingly poor because of attentional saturation, where we stop attending to details of frequently encountered objects. This lack of attention to details may leave us susceptible to misinformation effects. Across four experiments, we tested recognition memory for the Apple...

Although cognitive offloading, or the use of physical action to reduce internal cognitive demands, is a commonly used strategy in everyday life, relatively little is known about the conditions that encourage offloading and the memorial consequences of different offloading strategies for performance. Much of the extant work in this domain has focuse...

People are generally able to selectively attend and remember high-value over low-value information. Here, we investigated whether young and older adults would display typical value-based memory selectivity effects for to-be-learned item-value associations when goal-directed information about the meaning of associated values was presented before and...

People often rely on habitual, serial processing when presented with to-be-learned information. We tested how strategic processing can override more bottom-up, serial processes when remembering information by having participants study a list of word triads (e.g., “dollar phone pizza”). Participants' goal was manipulated by maximizing either (i) the...

People tend to better remember same-race faces relative to other-race faces (an “own-race” bias). We examined whether the own-race bias extends to associative memory, particularly in the identification and recall of information paired with faces. In Experiment 1, we presented white participants with own- and other-race faces which either appeared a...

An individual’s outlook on society can change over time and can be related to both their physical and mental health. Here, we developed an instrument to measure outlooks on the past and future in relation to the present in 413 adults ranging in age from 18 to 80 years. Exploratory and confirmatory factor analyses were conducted on independent sampl...

Digitized specimens are an indispensable resource for rapidly acquiring big datasets and typically must be pre‐processed prior to conducting analyses. One crucial image pre‐processing step in any image analysis workflow is image segmentation, or the ability to clearly contrast the foreground target from the background noise in an image. This proced...

Given natural memory limitations, people can generally attend to and remember high-value over low-value information even when cognitive resources are depleted in older age and under divided attention during encoding, representing an important form of cognitive control. In the current study, we examined whether tasks requiring overlapping processing...

Test anxiety is a context-specific academic anxiety which can result in poorer academic and metacognitive performance. We assessed how the quantity and relative weight of assessments contribute to the effects of test anxiety on performance and metacognitive accuracy in a smaller seminar-style class on human memory (study 1) and a larger lecture-sty...

Ecological and evolutionary processes govern the fitness, propagation, and interactions of organisms through space and time, and viruses are no exception. While COVID-19 research has primarily emphasized virological, clinical, and epidemiological perspectives, crucial aspects of the pandemic are fundamentally ecological or evolutionary. Here, we hi...

The 2019 novel coronavirus disease (COVID-19) has broadly impacted our daily lives. Here, we used a longitudinal approach to investigate older adults’ mood and expectations regarding aging before and during the global pandemic (Study 1). We also examined age differences in mood, expectations regarding aging, COVID-19 attitudes, and loneliness using...

People often need to remember the location of important objects or events, and also to remember locations that are associated with negative objects. In the current study, we examined how both positive and negative items might be selectively remembered in the visuospatial domain. Participants studied number-items ranging from -25 to +25 indicating p...

Coral reef fishes constitute one of the most diverse assemblages of vertebrates on the planet. Color patterns are known to serve a number of functions including intra- and inter-specific signaling, camouflage, mimicry, and defense. However, the relative importance of these and other factors in shaping color pattern evolution is poorly understood. H...
