Contingency analyses have been employed to assess the degree to which outcomes of successive tests of corresponding items deviate from stochastic independence. A method of adjusting contingency tables to remove the effects of subject and item inhomogeneities, is presented. The method represents a partial solution to the "Simpson's…

Links between theory of mind and episodic memory involving autonoetic consciousness were investigated in Japanese 4- to 6-year-olds. After age was controlled for, most theory of mind abilities showed no interrelations. Own and others' belief understandings on deceptive appearance tasks were solely related to source memory. Results suggest that…

Using 49 undergraduates, short-term memory (STM) spans, STM probe-recall tasks, and complex working memory (WM) spans were studied to assess the relationships among STM, WM, and verbal ability. Results indicate that STM and WM are separate cognitive constructs, and that both STM and WM are important to verbal abilities. (SLD)

Explores whether indirect measures of memory are associated with age. Results, based on 30 younger and 30 older adults, suggest that direct measures, such as number of words recalled, were related to age, whereas indirect measures (consistency of order of presentation of words recalled) were not associated with age. (RJM)

The aim of this study was to examine the psychometric properties of a French version of the Multifactorial Memory Questionnaire (MMQ) (Troyer & Rich, 2002). The MMQ, which is suited to clinical and research purposes, evaluates subjective memory functioning (i.e., affect related to memory abilities, frequency of problems remembering in different…

Studies of sentence comprehension deficits in Parkinson's disease (PD) patients suggest that language processing involves circuits connecting subcortical and cortical regions. Anatomically segregated neural circuits appear to support different cognitive and motor functions. To investigate which functions are implicated in PD comprehension…

CF-1 male mice were trained in an inhibitory avoidance task using a high footshock (1,2 mA, 50 Hz, 1 sec) in order to reduce the influence of extinction on retention performance. At 2, 7, 14, or 30 d after training, the first retention test was performed and hemicholinium (HC-3, 1.0 microgram/mice), a specific inhibitor of high-affinity choline…

Voltage-gated potassium channels (Kv) are critically involved in learning and memory processes. It is not known, however, whether the expression of the Kv1.1 subunit, constituting Kv1 channels, can be specifically regulated in brain areas important for learning and memory processing. Radioactive in situ hybridization was used to evaluate the…

To investigate the stability of trace reactivation in healthy older adults, 22 older volunteers with no significant neurological history participated in a cross-modal priming task. Whilst both object relative center embedded (ORC) and object relative right branching (ORR) sentences were employed, working memory load was reduced by limiting the…

Overview: Behavioural data reveal an inverted U-shaped function in the efficiency of prospective memory from childhood to young adulthood to later adulthood. However, prior research has not directly compared processes contributing to age-related variation in prospective memory across the lifespan, hence it is unclear whether the same factors…

In this review, we report on studies that have assessed the effects of exogenous and endogenous increases in stress hormones on human cognitive performance. We first describe the history of the studies on the effects of using exogenous stress hormones such as glucocorticoids as anti-inflammatory medications on human cognition and mental health.…

Objective: Though children exposed to familial violence are reported to have difficulties with a range of emotional and behavioral problems (e.g., lower school achievement) that implicate executive function (EF) deficits, relatively little research has specifically examined EF as a function of trauma exposure in children. Methods: Based on parent…

This study investigated whether good novice problem solvers have their knowledge arranged around problem types to a greater extent than poor problem solvers have. Twelve problem types (see appendix) were distinguished according to underlying physics principles and 65 knowledge elements were printed on cards for university students to sort.…

Article investigated the relations between the types of error and their connections with auditory discrimination and auditory memory. (Editor/RK)

To determine the extent of students' confidence-judgment accuracy (CJA) and the relationship of this memory-monitoring ability to overall test performance, undergraduates in a psychology course supplied confidence-judgments along with their answers on multiple-choice test items. CJA correlated positively with test performance. (Editor/SJL)
