There are very few case series of patients with acute psychogenic memory loss (also known as dissociative/functional amnesia), and still fewer studies of outcome, or comparisons with neurological memory-disordered patients. Consequently, the literature on psychogenic amnesia is somewhat fragmented and offers little prognostic value for individual patients. In the present study, we reviewed the case records and neuropsychological findings in 53 psychogenic amnesia cases (ratio of 3:1, males:females), in comparison with 21 consecutively recruited neurological memory-disordered patients and 14 healthy control subjects...

A central hypothesis of recovered memory is that the source of the memory may be misattributed, and the memory of an imagined event may be mistaken as the memory of the perceived event that was not remembered. The judgment of memory source depends upon phenomenological characteristics. Thus, the present study investigated characteristics of recovered memory. To exclude potential confounding effects of traumatic stress and acute mental illness, data on recovered memories of diverse valences in a nonclinical sample were collected...

Research suggests that odors may serve as a potent cue for autobiographical retrieval. We tested this hypothesis in Alzheimer's disease (AD) and investigated whether odor-evoked autobiographical memory is an involuntary process that shares similarities with music-evoked autobiographical memory. Participants with mild AD and controls were asked to retrieve two personal memories after odor exposure, after music exposure, and in an odor-and-music-free condition. AD participants showed better specificity, emotional experience, mental time travel, and retrieval time after odor and music exposure than in the control condition...

Background: Eye movement desensitization and reprocessing (EMDR) is an effective psychological treatment for posttraumatic stress disorder. Recalling a memory while simultaneously making eye movements (EM) decreases a memory's vividness and/or emotionality. It has been argued that non-specific factors, such as treatment expectancy and experimental demand, may contribute to the EMDR's effectiveness. Objective: The present study was designed to test whether expectations about the working mechanism of EMDR would alter the memory attenuating effects of EM...

The current paper offers a selective review of the study of memory appraisal, focusing on recollections of the personal past, with the goal to bring attention to a missing component in this study. To date, memory appraisal studies have concentrated on participants' assessments of the content of their personal recollections (e.g., their perceptual detail and story-like feel), including beliefs about the accuracy of that content. Participants' assessments of reflection processes accompanying their recollections (e...

REVIEW

The aversive experience we call "pain" results from the coordinated activation of multiple brain areas, commonly described as a "pain matrix". This is not a fixed arrangement of structures but rather a fluid system composed of several interacting networks: A 'nociceptive matrix' includes regions receiving input from ascending nociceptive systems, and ensures the bodily characteristics of physical pain. A further set of structures receiving secondary input supports the 'salience' attributes of noxious stimuli, triggers top-down cognitive controls, and -most importantly- ensures the passage from pre-conscious nociception to conscious pain...

The self is a multi-faceted and temporally dynamic construct reflecting representations and beliefs about identity in the past, present, and future. Clinical studies have shown that individuals with Posttraumatic Stress Disorder (PTSD) and Social Anxiety Disorder (SAD) exhibit alterations in self-related processing but these studies have focused primarily on memory. Few studies in PTSD and SAD have examined self-related processing for the present and future, and no studies have directly compared these processes across these two disorders...

Thoughts about the future reflect personal goals, and projections into the future enrich our emotional life. Researchers have taken an interest in determining whether the tendency to remember more positive than negative emotional events observed when recalling past events also appears when remembering imagined future events. The objective of this study was to examine the age-based positivity effect of recall for future positive and negative autobiographical events in young and older adults. Representative future events were first established to develop the cues used to prompt personal future events...

The problem of recovered memories concerns not only psychiatry, psychology or psychotherapy but it is also an important legal and judicial issue. Clinicians, scientists and lawyers are in unsolved dispute, called "memory wars", concerning the credibility of these memories, especially if they were recovered following specific therapeutic techniques or using self-help books. Many cases of recovered memories of childhood sexual abuse brought legal action against alleged offender. Investigations showed, however, that some of these memories were false...

Rumination and cognitive reactivity (dysfunctional cognitions after sad mood-induction) remain high in remitted Major Depressive Disorder (MDD) and can contribute to new episodes. These factors have been linked to increased fMRI resting-state functional-connectivity within the Default-Mode Network (DMN). It remains unclear whether (I) increased DMN-connectivity persists during MDD-remission, and (II) whether sad mood-induction differentially affects DMN-connectivity in remitted-MDD versus controls. Moreover, DMN-connectivity studies in remitted-MDD were previously confounded by antidepressant-use...

The emotional aspect of autobiographical memories (AMs) is associated with self-related processing, which plays an important role in mental health. However, the emotional consistency dimension of AMs and its neural underpinnings remain largely unexplored. Twenty-five healthy participants were involved in this study. Participants were first asked to recall important AMs and assess the emotional ratings of each AM. Four weeks later, they were asked to retrieve the details of both positive and negative AMs during functional magnetic resonance imaging (fMRI) scanning...

Development of autobiographical memory is as a gradual process beginning in early childhood and continuing through late adolescence. Substantial attention has been paid to early childhood when first personal memories are formed; less attention has been focused on the flourishing of memories from the late preschool years onward. We addressed this void with a three-year cohort-sequential study of age-related changes in the length, completeness, and coherence of autobiographical narratives by children 4-10 years...

OBJECTIVES: Assessment of post-electroconvulsive therapy (ECT) disorientation at a single time point after ECT treatment may prove an effective and clinically useful method for monitoring the severity of disorientation and predicting ECT-induced retrograde amnesia. In this study, we aimed to validate a novel instrument (10-Item Orientation Questionnaire) developed to assess the level of disorientation after ECT. METHODS: Twenty-four depressed inpatients who were prescribed an acute course of ECT were administered the 10-Item Orientation Questionnaire at 30 minutes after ECT and had time to reorientation assessed at 3 time points after ECT (10, 30, and 60 minutes) at ECT treatments 1 to 3...

This article argues that the relationships between culture and development are differential and systematic. Therefore the presentation of the Western middle-class developmental pathway in textbooks as universal is grossly neglecting the reality and the psychologies of the majority of the world' s population. First, the conception of culture as the representation of environmental conditions is presented. The level of formal education acts as organizer of social milieus that define different learning environments for children...

Folk wisdom often refers to odours as potent triggers for autobiographical memory, akin to the Proust phenomenon that describes Proust's sudden recollection of a childhood memory when tasting a madeleine dipped into tea. Despite an increasing number of empirical studies on the effects of odours on cognition, conclusive evidence is still missing. We set out to examine the effectiveness of childhood and non-childhood odours as retrieval cues for autobiographical memories in a lab experiment. A total of 170 participants were presented with pilot-tested retrieval cues (either odours or images) to recall childhood memories and were then asked to rate the vividness, detail, and emotional intensity of these memories...

An approach to learning words known as "fast mapping" has been linked to unique neurobiological and behavioral markers in adult humans, including rapid lexical integration. However, the mechanisms supporting fast mapping are still not known. In this study, we sought to help change this by examining factors that modulate learning outcomes. In 90 subjects, we systematically manipulated the typicality of the items used to support fast mapping (foils), and quantified learners' inclination to employ semantic, episodic, and spatial memory through the Survey of Autobiographical Memory (SAM)...

When people revisit past autobiographical events they often imagine alternative ways in which such events could have occurred. Often these episodic counterfactual thoughts (eCFT) are momentary and fleeting, but sometimes they are simulated frequently and repeatedly. However, little is known about the neural differences between frequently versus infrequently repeated eCFT. The current study explores this issue. In a three-session study, participants were asked to simulate alternative ways positive, negative, and neutral autobiographical memories could have occurred...

Autobiographical memory (AM), episodic memory for life events, involves the orchestration of multiple dynamic cognitive processes, including memory access and subsequent elaboration. Previous neuroimaging studies have contrasted memory access and elaboration processes in terms of regional brain activation and connectivity within large, multi-region networks. Although interactions between key memory-related regions such as the hippocampus and prefrontal cortex (PFC) have been shown to play an important role in AM retrieval, it remains unclear how such connectivity between specific, individual regions involved in AM retrieval changes dynamically across the retrieval process and how these changes relate to broader memory networks throughout the whole brain...

BACKGROUND: There is little literature on the relative efficacy and cognitive safety of right unilateral (RUL), bifrontal (BF), and bitemporal (BT) electroconvulsive therapy (ECT) in schizophrenia. METHODS: We present a randomized, nonblind, naturalist comparison of a fixed course of 8 moderately high-dose RUL (n = 24), threshold BF (n = 27), and threshold BT (n = 31) ECT in patients with schizophrenia. Assessments included the Positive and Negative Syndrome Scale (PANSS), the Wechsler Memory Scale-Revised, and an autobiographical memory interview...

The continuity hypothesis (1) posits that there is continuity, of some form, between waking and dreaming mentation. A recent body of work has provided convincing evidence for different aspects of continuity, for instance that some salient experiences from waking life seem to feature in dreams over others, with a particular role for emotional arousal as accompanying these experiences, both during waking and while asleep. However, discontinuities have been somewhat dismissed as being either a product of activation-synthesis, an error within the consciousness binding process during sleep, a methodological anomaly, or simply as yet unexplained...
