“…This is a typical omission error, possibly fostered by the decreasing accessibility of memory over time (“transience”: Schacter, 1999 ; Schacter et al, 2003 ). Selective forgetting and remembering has traditionally been studied in relation to the confirmation bias (e.g., Levine and Murphy, 1943 ; Nickerson, 1998 ). Mather et al (2000) and Depping and Freund (2013) have investigated the occurrence of this phenomenon after choice.…”

Choice-Supportive Misremembering: A New Taxonomy and Review

Although the literature on the influence of memory on decisions is well developed, research on the effects of decision making on memory is rather sparse and scattered. Choice-supportive misremembering (i.e., misremembering choice-related information that boosts the chosen option and/or demotes the foregone options) has been observed in several studies and has the potential to affect future choices. Nonetheless, no attempt has been made to review the relevant literature, categorize the different types of choice-supportive misremembering observed, and critically appraise the existing evidence and proposed explanations. Thus, starting from a new theoretically motivated and empirically grounded taxonomy, we review the current research. Our taxonomy classifies choice-supportive misremembering into four conceptually distinct types: misattribution is when information is attributed to the wrong source, fact distortion when the facts are remembered in a distorted manner, false memory when items that were not part of the original decision scenarios are remembered as presented and, finally, selective forgetting is when information is selectively forgotten. After assessing the impact of various potentially moderating factors, we evaluate the evidence for each type of misremembering and conclude that the support for the phenomenon is solid in relation to misattribution when recognition memory is assessed, but significantly weaker for the other three types, and when other memory tests are used to assess memory. Finally, we review the cognitive and emotional explanations proposed for choice-supportive misremembering in the light of the available evidence and identify the main gaps in the current knowledge and the more promising avenues for future research.

“…Acute amnesia is uncommon in patients with acute cerebral infarction and is initially misdiagnosed in approximately half the patients with this condition [1]. If it does occur, the causative lesions are usually located in the mesiotemporal lobe and hippocampus, thalamus, basal forebrain, or retrosplenial cortex [1][2][3][4]. Recently, several studies have demonstrated that fornical infarction can cause memory deficits; however, these lesions often involved the surrounding structures, such as the corpus callosum, hippocampus, or cingulate gyrus [5,6].…”

A 49-year-old woman with poorly controlled hypertension was admitted to our hospital for sudden memory deficit. Her daughter noticed that she repeatedly asked about the time for lunch on the day before admission and her inability to recall storylines on television programs. However, the patient recognized her daughter and other family members. She did not experience fatigue, fever, or diarrhea before the onset of amnesia. Her memory impairment was persistent. Headaches, convulsions, or limb movement disorders were absent. She had no history of smoking, drinking, trauma, drug abuse, or exposure to toxins. The findings of the neurological examination were unremarkable, except for the reduction in memory and calculation abilities, which manifested as the inability to recall incidents that occurred minutes ago, along with reiterations of the same questions. Her Mini-Mental State Examination score was 21, with deficits in the immediate memory (0/3), recall (0/3), and calculation (2/5) categories. The result of the Montreal Objective Cognitive Assessment was normal, with the exception of recall and calculation.The patient's blood pressure at admission was 170/105 mm Hg. Serum total cholesterol and low-density lipopro-

Basal Forebrain Amnesia

Abstract: This patient is different from patients with hippocampal or diencephalic lesions, and is similar to other patients reported with basal forebrain lesions. The main difference is the relation between his flat learning curve and preserved recognition, both for visual and verbal material.
