An fMRI study of long-term everyday memory using SenseCam

We used a novel automatic camera, SenseCam, to investigate recognition memory for real-life events at a 5-month retention interval. Using fMRI we assessed recollection and familiarity memory using the remember/know procedure. Recollection evoked no medial temporal lobe (MTL) activation compared to familiarity and new responses. Instead, recollection activated diverse regions in neocortex including medial prefrontal cortex. We observed decreased activation in anterior hippocampus/ anterior parahippocampal gyrus (aPHG) at 5 months compared to a 36-hour retention interval. Familiarity was associated with greater activation in aPHG and posterior parahippocampal gyrus (pPHG) than recollection and new responses. Familiarity activation decreased over time in anterior hippocampus/aPHG and posterior hippocampus/pPHG. The engagement of neocortical regions such as medial prefrontal cortex at a 5-month delay, together with the reduced MTL activation at 5 months relative to at 36 hours is in line with the assumptions of Consolidation theory. SenseCam provides a valuable technique for assessing the processes that underlie remote everyday recognition memory.     

The causes and consequences of transient epileptic amnesia

Transient epileptic amnesia (TEA) is a recently recognised syndrome of epilepsy in which the principle manifestation of seizures is recurrent episodes of isolated memory loss. In this article, we describe the clinical and cognitive profile of this emerging syndrome, and present new data that provide at most weak support for its proposed relationship to cerebrovascular disease. TEA is often associated with two unusual forms of interictal memory impairment: accelerated long-term forgetting and remote memory impairment. We discuss the clinical and theoretical implications of these relatively novel cognitive deficits.     

Factor analytic evaluation of differences between black and caucasian emotionally disturbed children on the children's depression inventory

Scores on the Children's Depression Inventory (CDI) for 392 Caucasian and 159 black psychiatric inpatients between 6 and 18 years of age were subjected to principal-components factor extraction with Varimax rotation. Factors not contributing to variance were eliminated using the scree test (Cattell, 1966) and the degree of variance accounted for by remaining factors for both groups was examined through respective squared multiple correlations. A comparison of CDI factors for blacks and Caucasians indicated some differences, with blacks be ing less suicidal yet higher on other behavioral dimensions, such as oppositionality, and Caucasians higher on affective dimensions, such as sadness. The results support research on black-Caucasian differences and suggest the need to validate further the CDI with minority populations.

Reliability of the Children's Attitudes Toward the Environment Scale

The Children's Attitudes toward the Environment Scale, developed by Musser and Malkus (1994), gave Cronbach alpha .73 and .83 at pretest and 3-wk. later for 274 children and a test-retest r of only .47. While Cronbach alpha was similar to the value reported by the test developers, it is close to the low end of acceptability.
