Did you hear? Auditory prospective memory cues are more beneficial for autistic than for non-autistic children and adolescents
2021
Item does not contain fulltext Background: The transition from primary to secondary school is particularly difficult for autistic children, a transition underpinned by an increase in prospective memory (PM) demands. Aims: To better understand PM in autistic children of the relevant age range and its underlying processes, the current study investigated the impact of cue salience (distinctiveness) on PM in autistic and non-autistic children and adolescents. The study was unique in manipulating the visual and auditory salience of PM cues. Salient cues are assumed to put lower demands on executive control resources as compared to cues that blend in with the ongoing activity. Methods and procedu…
Age-related differences in the neural correlates of remembering time-based intentions.
2012
The present study used event-related potentials (ERPs) to explore the effect of age on the neural correlates of monitoring processes involved in time-based prospective memory.In both younger and older adults, the addition of a time-based prospective memory task to an ongoing task led to a sustained ERP activity broadly distributed over the scalp. Older adults, however, did not exhibit the slow wave activity observed in younger adults over prefrontal regions, which is considered to be associated with retrieval mode. This finding indicates that age-related decline in intention maintenance might be one source of the impaired prospective memory performance displayed by older adults. An 'anterio…
The role of noticing in prospective memory forgetting.
2007
Two experiments used autonomic reactions (i.e., skin conductance responses; SCRs) in conjunction with behavioral responses to study retrieval processes in prospective memory. SCRs were recorded while participants performed a prospective memory task embedded in an ongoing task. Stimuli that received the same behavioral response (i.e., no prospective memory response) evoked different autonomic reactions as a function of whether they were versus were not prospective cues (Experiments 1 and 2) and as a function of whether they did versus did not share perceptual or conceptual features with prospective cues (Experiment 2). To the extent that SCRs provide an index of noticing a stimulus, increase…
‘If-then’ but when? Effects of implementation intentions on children’s and adolescents’ prospective memory
2021
Abstract Prospective memory (PM), the ability to initiate and implement delayed intentions, increases across childhood and adolescence. Previous evidence on older adults indicated beneficial effects of implementation intentions (an encoding strategy) on individuals’ PM performance; especially when cognitive control demands were high and availability of cognitive resources low. This research program set out to investigate the impact of implementation intentions on children’s and adolescents’ PM while simultaneously varying cognitive control demands of the PM paradigm. Across two studies, implementation intention encoding was contrasted with standard encoding. In addition, Study 1 manipulated…
Episodic future thinking together with observational learning benefits prospective memory in high-functioning Korsakoff's syndrome patients
2020
Contains fulltext : 219555.pdf (Publisher’s version ) (Open Access) Objective: Patients with Korsakoff's syndrome (KS) have difficulty carrying out tasks which rely on prospective memory (PM). Since remembering to carry out an action in the future is crucial for living independently, it is of primary interest to develop strategies that improve PM performance in KS patients. Design: The study employed a computer categorization task as an ongoing activity into which a PM task was embedded. We included episodic future thinking (EFT) and observational learning (Experiment 2) to boost PM. Methods: Experiment 1 evaluated the efficacy of EFT following written PM task instructions in ten KS patient…
Electrophysiological correlates of strategic monitoring in event-based and time-based prospective memory
2012
Prospective memory (PM) is the ability to remember to accomplish an action when a particular event occurs (i.e., event-based PM), or at a specific time (i.e., time-based PM) while performing an ongoing activity. Strategic Monitoring is one of the basic cognitive functions supporting PM tasks, and involves two mechanisms: a retrieval mode, which consists of maintaining active the intention in memory; and target checking, engaged for verifying the presence of the PM cue in the environment. The present study is aimed at providing the first evidence of event-related potentials (ERPs) associated with time-based PM, and at examining differences and commonalities in the ERPs related to Strategic M…
Keeping memory for intentions: A cTBS investigation of the frontopolar cortex
2011
The present study aimed to investigate the role of frontopolar cortex in prospective memory (PM) by means of inhibitory theta-burst stimulation (cTBS). "Experiment 1"-8 volunteers were evaluated after inhibitory cTBS over left Brodmann area (BA) 10, right BA10, and Cz. In the PM procedure, sequences of 4 words each were presented. During the intersequence delay, subjects had to repeat the sequence in the observed order (ongoing task forward) or in the reverse order (backward). At the occurrence of a target word, subjects had to press a key on the keyboard (PM task). Recall and recognition of the target words were also tested. PM accuracy was lower after cTBS over left BA10 compared with Cz …
The Right Frontopolar Cortex Is Involved in Visual-Spatial Prospective Memory
2013
The involvement of frontopolar cortex in mediating prospective memory processes has been evidenced by various studies, mainly by means of neuroimaging techniques. Recently, one transcranial magnetic stimulation study documented that transient inhibition of left Brodmann Area (BA) 10 impaired verbal prospective memory. This result raises the issue of whether the BA 10 involvement in prospective memory functioning may be modulated by the physical characteristics of the stimuli used. The present study aimed to investigate the role of the frontopolar cortex in visual-spatial PM by means of the application of inhibitory theta-burst stimulation. Twelve volunteers were evaluated after inhibitory t…
Being in the Past and Perform the Future in a Virtual World: VR Applications to Assess and Enhance Episodic and Prospective Memory in Normal and Path…
2020
The process of aging commonly features a gradual deterioration in cognitive performance and, in particular, the decline of memory. Despite the increased longevity of the world's population, the prevalence of neurodegenerative conditions, such as dementia, continues to be a major burden on public health, and consequently, the latest research has been focused on memory and aging. Currently, the failure of episodic and Prospective memory (PM) is one of the main complaints in the elderly, considered among the early symptoms of dementia. It is therefore increasingly important to define more clearly the boundaries between normal and pathological aging. Recently, researchers have begun to build an…
The effects of collaboration and punishment on prospective memory performance in a group setting
2020
Contains fulltext : 225210.pdf (Publisher’s version ) (Open Access) Remembering to perform a delayed intention is termed prospective memory (PM). Often delayed intentions are shared by more than one person; however, there is a dearth of studies examining PM in social settings. We aimed to investigate whether the potential consequences of one's behavior across diverse group settings influence PM performance in event- and time-based tasks. A total of 207 participants were randomly allocated to either an individual, collaborative, or collaborative plus penalty motivation condition and were tested in a 2- or 3-person setting. For the time-based PM task, participants responded less timely in the…
