RESUMEN

When learning, it is often necessary to identify important themes to organize key concepts into categories. In value-directed remembering tasks, words are paired with point values to communicate item importance, and participants prioritize high-value words over low-value words, demonstrating selective memory. In the present study, we paired values with words based on category membership to examine whether being selective in this task would lead to a transfer of learning of the "schematic reward structure" of the lists with task experience. Participants studied lists of words paired with numeric values corresponding to the categories the words belonged to and were asked to assign a value to novel exemplars from the studied categories on a final test. In Experiment 1, instructions about the schematic structure of the lists were manipulated between participants to either explicitly inform participants about the list categories or to offer more general instructions about item importance. The presence of a visible value cue during encoding was also manipulated between participants such that participants either studied the words paired with visible value cues or studied them alone. Results revealed a benefit of both explicit schema instructions and visible value cues for learning, and this persisted even after a short delay. In Experiment 2, participants had fewer study trials and received no instructions about the schematic structure of the lists. Results showed that participants could learn the schematic reward structure with fewer study trials, and value cues enhanced adaptation to new themes with task experience.

RESUMEN

ABSTRACTPeople 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 alone or accompanied by a label indicating whether the face was a "criminal" or a "victim". Results revealed an own-race facial recognition advantage regardless of the presence of associative information. In Experiment 2, we again paired same- and other-race faces with either "criminal" or "victim" labels, but rather than a recognition test, participants were asked to identify whether each face had been presented as a criminal or a victim. White criminals were better categorised than Black criminals, but race did not influence the categorisation of victims. In Experiment 3, white participants were presented with same- and other-race faces and asked to remember where the person was from, their occupation, and a crime they committed. Results revealed a recall advantage for the associative information paired with same-race faces. Collectively, these findings suggest that the own-race bias extends to the categorisation and recall of information in associative memory.

RESUMEN

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 samples and test-retest reliability was assessed in a subset of participants. Construct validity of the two past and future scales was assessed by relating them to 1) pre-existing scales measuring related constructs, and 2) beliefs and safety behaviors during the COVID-19 pandemic. The final Bright or Bleak Scale (BOBS) consists of a past and future scale, each with two factors measuring societal and personal outlooks. Brighter future societal and personal outlooks were positively associated with longer future time perspectives, while self-reporting a higher likelihood of already having contracted COVID-19 was related to bleaker past societal and personal outlooks.

RESUMEN

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 a cross-sectional approach (Study 2). In Study 1, older adults completed a mood and expectations regarding aging survey up to 2 years prior to the pandemic and again in April, 2020 (during the pandemic). Participants also completed surveys regarding COVID-19 attitudes and loneliness. In Study 2, a United States sample of younger and older adults completed these surveys during the pandemic. Older adults' mood and expectations regarding aging remained fairly constant, and younger adults showed lower mood and expectations regarding aging than did older adults, despite older adults showing greater concern about COVID-19. Overall, we find that some older adults seem to be resilient with respect to their mood and expectations regarding aging. These findings reveal important preliminary implications for how older adults may be impacted as a result of lifestyle changes necessary for well-being and the well-being of society.
