Recent studies established that making concurrent judgments of learning (JOLs) can significantly alter (typically enhance) memory itself--a "reactivity" effect. The current study recruited 190 Chinese children (M[subscript age] = 8.68 years; 101 female) in 2020 and 2021 to explore the reactivity effect on children's learning, its…

In the present study, we investigated the impact of a word-problem intervention in retention and acquisition of knowledge after the intervention ended. We based analyses upon Grade 4 students experiencing mathematics difficulty (average age at pretest = 8.77) who received one of two variants of a word-problem intervention (with [n = 111] vs.…

Abilities to encode and remember events in their spatiotemporal context (episodic memory) rely on brain regions that mature late during childhood and are supported by sleep. We compared the temporal dynamics of episodic memory formation and the role of sleep in this process between 62 children (8-12 years) and 57 adults (18-37 years). Subjects…

In two studies of knowledge about the properties and processes of memory for the times of past events, 178 children from 5 through 13 years of age and 40 adults answered questions about how they would remember times on different scales, how temporal memory is affected by retention interval, and the usefulness of different methods. The adults…

In 1 experiment, infants' ability to retain a memory for 24 hours was disrupted when infants were trained in 1 situational context and tested in another but not when they were trained in multiple contexts. In a second experiment, training in multiple contexts did not facilitate memory retrieval in a novel context after a long delay. (BC)

The goal of this investigation was to study the regulatory retention effects of an adult's emotional displays on infant behavior. In Study 1, 11- and 14-month-old infants were tested in a social-referencing-like paradigm in which a 1-hr delay was imposed between the exposure trials and the test trial. In Study 2, 11-month-olds were tested in the…

The effects of cumulative-rehearsal instructions and degree of overlearning on first graders' acquisition and transfer of rehearsal strategies were investigated. (JMB)

In two studies, four- but not three-year olds understood that (1) of two characters who saw an object, the one who waited longer before attempting to find it would not remember where it was; and (2) of two objects seen by a character, the object seen long ago would be forgotten and the object seen recently would be remembered. (BC)

Assesses the long-term retention of conditioned operant footkicks by three-month-old infants. Views a conditioning analysis as a logical means by which to bridge the gap between animal and adult human models of memory. (Author/RH)

Two studies assessed the effects of material incentives and feedback on the use of rehearsal by first grade children. Subjects were required to remember the order in which the experimenter pointed to simple objects and rehearsal was assessed by observing lip movements during a 15-second retention interval. (Author/DB)

The ability of six-month-old infants to remember a functional category acquired in a specific context was assessed in three experiments. Findings revealed that at six months, information about the place where categories are constructed is prerequisite for retrieval of a category concept from long-term memory. (GLR)

Assessed 2-year olds' ability to use semantic context to infer meanings of novel nouns and to retain those meanings. Found that children learned majority of novel words; however, they occasionally failed to choose the correct corresponding picture for a novel noun even when they understood the verb; also found a significant retention of newly…

It was concluded that age and IQ have strong influences on acquisition-retrieval, but that forgetting rate is independent of these variables. (Author)

Examines story retention after one-week interval as a function of topic familiarity and test-item relatedness. Second- and fifth-grade children participated. (MP)

The present study was designed to determine whether a reactivation procedure (consisting of the experimenter's manipulation of a previously experienced overhead crib mobile) would alleviate infant's poor retention after a 14-day interval. It is concluded that forgetting by young infants may result from failures in retrieval, and not failures in…
