Combined Mnemonic Strategy Training And High-Definition Transcranial Direct Current Stimulation For Memory Deficits In Mild Cognitive Impairment, Benjamin M. Hampstead, Krishnankutty Sathian, Marom Bikson, Anthony Y. Stringer

Publications and Research

Introduction: Memory deficits characterize Alzheimer’s dementia and the clinical precursor stage known as mild cognitive impairment. Nonpharmacologic interventions hold promise for enhancing functioning in these patients, potentially delaying functional impairment that denotes transition to dementia. Previous findings revealed that mnemonic strategy training (MST) enhances long-term retention of trained stimuli and is accompanied by increased blood oxygen level–dependent signal in the lateral frontal and parietal cortices as well as in the hippocampus. The present study was designed to enhance MST generalization, and the range of patients who benefit, via concurrent delivery of transcranial direct current stimulation (tDCS).

Age-Related Differences In Context-Specificity Benefits Ambiguous Predictive Learning, Catherine Luna

Mahurin Honors College Capstone Experience/Thesis Projects

The present study investigated age differences in the context-specificity effect in learning. Ambiguity was manipulated in two conditions in a predictive learning paradigm (Callejas-Aguilera & Rosas, 2010) to encourage participants to attend to context. In the ambiguous condition, foods led to the presence of the illness equally as often as its absence. In the non-ambiguous condition, foods consistently led to the presence of the illness or consistently lead to its absence. Participants were instructed to make predictive judgments for foods leading to the presence of an illness in one of two restaurant contexts. During the test, participants made predictive judgments …
