Wechsler Memory Scale-Revised (WMS-R) scores were analyzed for 82 epilepsy surgery candidates and used in combination with receiver operating characteristic curves to classify patients with left (LTL) and right (RTL) temporal lobe seizure onset. Results indicate that WMS-R scores used alone or in combination provide relatively poor discrimination…

Investigated time delays (immediate, two-three days, one week) between viewing a staged theft and attempting an eyewitness identification. Compared lineups to one-person showups in a laboratory analogue involving 412 subjects. Results show that across all time delays, participants maintained a higher identification accuracy with the showup…

Investigated the effects of the presence and typicality of detail in a witness' testimony on mock juror judgments. Results indicate that the presence of detail affected the ratings of witnesses. Atypical or typical detail provided by one witness, with no detail provided by the opposing witness, enhanced assessments of the former. (RJM)

Two studies explored the following two issues important in understanding the development of knowledge-based inferencing: (1) how children of different ages use a circumscribed and available knowledge base to make two types of inferences important for comprehension; and (2) how the accessibility of an available knowledge base is related to…

Investigated preschool children's suggestibility following exposure to biased information. Children heard a story followed the next day by either biased, unbiased, or no information. Found that children were able to identify the original story details six days later when the questions were phrased in an explicit manner that referred to the time of…

Describes several "inaccurate" statements made in L. Thomas' and T. Levine's article in this journal (volume 21, page 103) regarding the current author's research and positions on the listening construct. Suggests that Thomas' and Levine's model has serious methodological flaws. (RS)

Presents comments about R. Bostrom's article in this journal. Suggests that Bostrom missed the point of Thomas' and Levine's original article. (RS)

In their homes, older adults who were not informed that they were to be given memory tests completed the Metamemory in Adulthood Questionnaire. Motivation and anxiety during testing had more effect on memory than did self-efficacy. The setting influenced performance. (SK)

Based on decades of research on learning and memory, this article asserts that "what you think about is what you remember," noting that implications for teaching and assignments are substantial. Suggests that in the early stages of learning, students may display shallow learning, but deep, connected knowledge must be encouraged by…

This study examined two alternative interpretations of violation-of-expectation findings that young infants can represent hidden objects. Findings indicated that 5-month-olds succeeded in reasoning about the interaction of a visible and a hidden object even though the 2 objects were never simultaneously visible and a 3- or 4-minute delay preceded…

Evaluated the criterion validity of the Mattis Dementia Rating Scale (S. Mattis, 1988) with a concurrent study to obtain a cut-off score for an Argentinean population by administering a battery of tests to 60 memory disorder patients. Findings demonstrate high convergent validity with another measure and show an appropriate cut score for use with…

Proposed three criteria to distinguish calendrical savants whose skills depend on memory from those who calculate and applied these to 10 calendrical savants. Results are discussed in relation to views that calendrical savants imply the existence of a modular mathematical intelligence or unconscious integer arithmetic. (SLD)

Children were exposed to an event and asked several days later to recall the event. Results showed that children's recall was more complete and accurate when the event was experienced instead of observed or heard about; and children's sensitivity to event structure was dependent on information source (experience, observation, story) and number of…

In a study of developmental differences in ability to suppress irrelevant information in working memory, children and adults provided endings for sentences that constrained a terminal noun. Responses to critical sentences were disconfirmed with unexpected endings. On another sentence-completion task with disconfirmed nouns, children showed priming…

Tested 133 college students in Germany with new tasks and 6 working memory marker tasks. Results reveal three working memory functions: simultaneous storage and processing; supervision; and coordination of elements into structures. Each function could be subdivided into distinct components of variance. (SLD)
