Two experiments are reported in which age differences in working memory performance are explored. In the first study, young and older adults held 2, 3, 4, or 5 unrelated words in mind while verifying a single or complex sentence. An age-related decrement was found in subsequent serial recall of the words, and this decrement was larger with longer word lists. Experiment 2 confirmed the interaction between age and list length, using list lengths of 4, 6, and 8 words and a free-recall procedure. There was no interaction between age and divided attention in either experiment. Surprisingly, sentence complexity had a greater detrimental effect on recall in the younger group. The results are discussed in terms of articulatory rehearsal being augmented by using secondary memory in the case of younger subjects. 相似文献

Media psychologists have long puzzled over how individuals can experience enjoyment from entertainment such as tragedies that often elicit profound feelings of sadness. The present research examines the idea that a focus on “meaningful” entertainment and affective responses identified as “elevation” may provide a framework for understanding many examples of sad or dramatic entertainment. The results of this study suggest that many types of meaningful cinematic entertainment feature portrayals of moral virtues (e.g., altruism). These portrayals, in turn, elicit feelings of elevation (e.g., inspiration) that are signified in terms of mixed affect and unique physical responses (e.g., lump in throat). Ultimately, elevation also gives rise to motivations to embody moral virtues, such as being a better person or helping others. 相似文献

Prenatal depressive symptoms have been linked to negative outcomes for mothers and children. Using attachment theory as a framework, this study examined developmental differences in the interpersonal context of prenatal depressive symptoms among adolescents (age 14 to 19 years; n = 352) and young adults (age 20 to 24 years; n = 348). Participants included low-income, single, predominantly African American and Latina women. Moderating and mediating factors were found in the relation between caregiving history (perceived unavailability and inconsistency of maternal and paternal figures during childhood) and depressive symptoms. For pregnant adolescents, maternal unavailability predicted depressive symptoms whereas maternal inconsistency did not. In contrast, for pregnant young women, only maternal inconsistency predicted depressive symptoms; and this association was mediated by perceptions of prenatal support. For both groups, paternal caregiving history had a small yet independent association with depressive symptoms. Results highlight the need to consider developmental differences in the interpersonal context of prenatal depressive symptoms in delivering mental health interventions to young women of color. 相似文献
