Computational models are tools for testing mechanistic theories of learning and development. Formal models allow us to instantiate theories of cognitive development in computer simulations. Model behavior can then be compared to real performance. Connectionist models, loosely based on neural information processing, have been successful in…

Posttraumatic stress disorder (PTSD) was first included in the American Psychiatric Association's "Diagnostic and statistical manual of mental disorders" in 1980. Long used to describe the reactions of soldiers affected by stress in combat situations, PTSD is now recognised as a disorder affecting abused and neglected infants and…

Although the issue of dissociative amnesia in adult survivors of child sexual abuse has been contentious, many research studies have shown that there is a subset of child sexual abuse survivors who have forgotten their abuse and later remembered it. Child sexual abuse survivors with dissociative amnesia histories have different formative and…

It is widely assumed that older adults suffer a deficit in the psychological processes that underlie remembering of contextual or source information. This conclusion is based in large part on empirical interactions, including disordinal ones, that reveal differential effects of manipulations of memory strength on recognition in young and old…

We previously reported a meta-analysis of explicit memory studies in populations with intellectual disability (ID). The current study discusses the educational implications of this meta-analysis. The main factors at the core of these implications can be divided into two categories: those related to task characteristics (e.g., depth of processing,…

S. Ghetti (2008) and M. L. Howe (2008) presented probative ideas for future research that will deepen scientific understanding of developmental reversals on false memory and establish boundary conditions for these counterintuitive patterns. Ghetti extended the purview of current theoretical principles by formulating hypotheses about how…

The medial temporal lobe memory system matures relatively early and supports rudimentary declarative memory in young infants. There is considerable development, however, in the memory processes that underlie declarative memory performance during infancy. Here we consider age-related changes in encoding, retention, and retrieval in the context of…

Explores the nature and consequences of developmental change in speed of information processing. Summarizes evidence indicating that age differences in processing speed reflect a global mechanism that limits processing speed on most tasks. Describes evidence that suggests a role for processing speed on the development of intelligence. (Author/MKA)

This study evaluates whether tip of the tongue experiences (TOTs) are caused by a more accessible word which blocks retrieval of the target word, especially for older adults. In a ''competitor priming'' paradigm, young and older adults produced the name of a famous character (e.g., Eliza Doolittle) in response to a question and subsequently named…

Relational complexity (RC) theory conceptualizes an individual's processing capacity and a task's complexity along a common ordinal metric. The authors describe the development of the Latin Square Task (LST) that assesses the influence of RC on reasoning. The LST minimizes the role of knowledge and storage capacity and thus refines the…

An adult developmental model of self-regulated language processing (SRLP) is introduced, in which the allocation policy with which a reader engages text is driven by declines in processing capacity, growth in knowledge-based processes, and age-related shifts in reading goals. Evidence is presented to show that the individual reader's allocation…

Results of a study indicated that adults reading for retention spent more time focusing on syntactic structure, while those reading for immediate comprehension focused more of their time on semantic content. However, the children (fifth graders) used reading strategies that involved mixtures of both of the adult components. (SL)

The study examined whether an awareness that semantic organization is beneficial to picture recall ("semantic enhancement") precedes an awareness that certain types of organization are more beneficial than others ("levels of processing"). A series of pilot studies was conducted with kindergarten and adult subjects and a formal…

Results of five experiments in which adults and children were exposed to two study strategies for vocabulary learning: (1) repetition of words with meanings and (2) associative elaboration (the keyword method). Subjects were asked to choose one of the two study methods for learning a 24-item list of new vocabulary words. (SL)

In this article, we focus on practical memory concerns in adulthood. Young, middle-aged, and community-dwelling older adults responded to seven open-ended questions covering the topics of memory self-efficacy, memory management, memory remediation, and fears about memory aging in adulthood. The results revealed several similarities among the age…
