Redefining the pattern of age-prospective memory-paradox: new insights on age effects in lab-based, naturalistic, and self-assigned tasks
© The Author(s) 2018Prospective memory (PM) involves remembering intended actions in the future, such as posting a letter when seeing a post box (event-based PM) or making a phone call at 2:00 pm (time-based PM). Studies on aging and PM have often reported negative age e ects in the laboratory, but positive age e ects in naturalistic tasks outside the laboratory (the so-called ageâPM-paradox). The present study re-examined this pattern of the paradox by studying, for the rst time, age di erences in time- and event-based PM in lab-based, experimenter-generated naturalistic and self-assigned real-life PM tasks within the same sample of young and older adults. Results showed that di erential age e ects in and outside the laboratory were quali ed by the type of PM cue. While age-related de cits were obtained for laboratory event-based tasks, no age e ect was obtained for naturalistic event-based PM. Age bene ts in the eld were only observed for naturalistic time-based tasks, but not for participantsâ own self-assigned time-based tasks. These ndings indicate that the age bene ts for naturalistic PM tasks may have been overestimated due to the dominant use of experimenter-generated naturalistic time-based PM tasks in previous studies. Therefore, the precise pattern of the ageâPM-paradox may need rede ning as mostly consisting of negative age e ects in lab-based PM tasks and mostly the absence of negative age e ects (rather than age bene ts) in naturalistic and self-assigned tasks outside the laboratory.Peer reviewedFinal Published versio
Adolescent Basic Facial Emotion Recognition Is Not Influenced by Puberty or Own-Age Bias
Basic facial emotion recognition is suggested to be negatively affected by puberty onset reflected in a âpubertal dipâ in performance compared to pre- or post-puberty. However, findings remain inconclusive. Further, research points to an own-age bias, i.e., a superior emotion recognition for peer faces. We explored adolescentsâ ability to recognize specific emotions. Ninety-five children and adolescents, aged 8â17 years, judged whether the emotions displayed by adolescent or adult faces were angry, sad, neutral, or happy. We assessed participants a priori by pubertal status while controlling for age. Results indicated no âpubertal dipâ, but decreasing reaction times across adolescence. No own-age bias was found. Taken together, basic facial emotion recognition does not seem to be disrupted during puberty as compared to pre- and post-puberty
Smartwatch reminders are as effective as verbal reminders in patients with Korsakoffâs syndrome: three case studies
Korsakoffâs syndrome (KS) is a neurocognitive disorder caused by severe malnutrition. KS patients typically show severe impairments in prospective memory (PM), thus, have difficulties with remembering to perform delayed intentions. The current study investigated the possible benefits of a smartwatch aid for PM tasks in patients with KS and compared its efficacy with verbal in-person reminders. Three patients participated in the present study and were asked to complete everyday PM tasks. The results of each patient were analyzed as a single-case study. The results highlight the great potential of using smartwatches as external memory aids in KS patients in everyday life

Effects of episodic future thinking and self-projection on childrenâs prospective memory performance
The present study is the first to investigate the benefits of episodic future thinking (EFT) at encoding on prospective memory (PM) in preschool (age: M = 66.34 months, SD = 3.28)and primary school children (age: M = 88.36 months, SD = 3.12). A second aim was to examine if self-projection influences the possible effects of EFT instructions. PM was assessed using a standard PM paradigm in children with a picture-naming task as the ongoing activity in which the PM task was embedded. Further, two first- and two second-order ToM tasks were administered as indicator of childrenâs self-projection abilities. Forty-one preschoolers and 39 school-aged children were recruited. Half of the participants in each age group were instructed to use EFT as a strategy to encode the PM task, while the others received standard PM instructions. Results revealed a significant age effect, with school-aged children significantly outperforming preschoolers and a significant effect of encoding condition with overall better performance when receiving EFT instructions compared to the standard encoding condition. Even though the interaction between age group and encoding condition was not significant, planned comparisons revealed first evidence that compared to the younger age group, older childrenâs PM benefited more from EFT instructions during intention encoding. Moreover, results showed that although self-projection had a significant impact on PM performance, it did not influence the effects of EFT instructions. Overall, results indicate that children can use EFT encoding strategies to improve their PM performance once EFT abilities are sufficiently developed. Further, they provide first evidence that in addition to executive functions, which have already been shown to influence the development of PM across childhood, self-projection seems to be another key mechanism underlying this development
Prospective memory performance in older people, adults and youth
The aims of this study were to verify the potential differences in prospective memory (PM) among young people, adults and
the elderly; analyze the relationships between variables of comprehension and verbal fluency and PM; and finally, verify
the existence of a relationship between self-reported health status and performance on PM. A cross- sectional design was
used. The study involved 270 participants divided into three age groups: young people aged 18 to 28 years; adults 45 to
55, and seniors 60 to 80. Their comprehension and verbal fluency skills were assessed as well as their self-perceived health
status. Subsequently, an experiment was carried out where participants were presented with paragraphs of three sentences
on a computer screen and they had to recognize previously agreed words that would indicate their level of MP. The results
established significant differences in prospective memory between adults and older people and between young people and the
elderly. But no differences between youth and adults were found..The importance of verbal comprehension and verbal fluency
in solving prospective memory experimental tasks was also significant. In addition, a better self-perception of well-being was
linked to a higher performance in PMEste trabajo fue posible gracias a la financiaciĂłn del grupo de investigaciĂłn HUM634 de la Junta de AndalucĂa y al contrato OTRI de este

Event-based prospective memory performance in autism spectrum disorder
The purpose of the present study was to investigate event-based prospective memory performance in individuals with autism spectrum disorder and to explore possible relations between laboratory-based prospective memory performance and everyday performance. Nineteen children and adolescents with autism spectrum disorder and 19 matched neurotypical controls participated. The laboratory-based prospective memory test was embedded in a visuo-spatial working memory test and required participants to remember to respond to a cue-event. Everyday planning performance was assessed with proxy ratings. Although parents of the autism group rated their childrenâs everyday performance as significantly poorer than controlsâ parents, no group differences were found in event-based prospective memory. Nevertheless, individual differences in laboratory-based and everyday performances were related. Clinical implications of these findings are discussed

Allocentric versus egocentric spatial memory in autism spectrum disorder
Individuals with Autism Spectrum Disorder (ASD) present difficulties in forming relations among items and context. This capacity for relational binding is also involved in spatial navigation and research on this topic in ASD is scarce and inconclusive. Using a computerised version of the Morris Water Maze task, ASD participants showed particular difficulties in performing viewpoint independent (allocentric) navigation, leaving viewpoint dependent navigation (egocentric) intact. Further analyses showed that navigation deficits were not related to poor visual short-term memory or mental rotation in the ASD group. The results further confirm the need of autistic individuals for support at retrieval and have important implications for the design of signposts and maps
