Sleep after learning aids memory recall

In recent years, the effect of sleep on memory consolidation has received considerable attention. In humans, these studies concentrated mainly on procedural types of memory, which are considered to be hippocampus-independent. Here, we show that sleep also has a persisting effect on hippocampus-dependent declarative memory. In two experiments, we examined high school students' ability to remember vocabulary. We show that declarative memory is enhanced when sleep follows within a few hours of learning, independent of time of day, and with equal amounts of interference during retention intervals. Sleep deprivation has a detrimental effect on memory, which was significant after a night of recovery sleep. Thus, fatigue accumulating during wake intervals could be ruled out as a confound.     

The spontaneous use of memory aids at different educational levels

Three groups of students in different educational levels: 8th–9th grade students (average age 15); 10th–11th grade students (average age 16); and college students (average age 21), completed a metamemory questionnaire on the use of external, general, and formal memory aids in everyday life and study situations. Short-term repetition, mental rehearsing, and summary elaboration were the most frequent aids. The least frequently used were those that require a special training to be used effectively (e.g. Digit-letters and method of loci). There were differences in the use of general memory aids due to education level, but not in the case of external and formal memory aids. Results showed also that women used memory aids more frequently than men.     

Commercial cognitive/memory systems: A case study

Commercial cognitive/memory systems are products that enhance human cognition and memory. Using one of our own product developments as a case study, we describe three phases of commercial systems development and evaluation. We review published examples of Phase One research, report two quasi-experimental investigations that are representative of successful Phase Two research, and provide some measures used to assess the product's success in the early stages of Phase Three. Finally, we discuss the use of theories and findings from basic research in cognitive psychology to develop products of value to individuals and society.     

Drawings as memory aids: Optimising the drawing method to facilitate young children's recall

There has been supportive evidence of drawing facilitating young children's event recall. The present study investigated whether additional event details are recalled if the interviewer uses interactive questions in response to information children have spontaneously drawn or verbally reported. Eighty 5‐ to 6‐year‐olds were shown a video clip of a novel event and were interviewed the following day. The children were randomly allocated to one of four recall conditions: tell‐only, draw‐and‐tell, interactive draw‐and‐tell and interactive tell‐only. The children's verbal reports were transcribed and scored on four different categories of recall: items (objects and people), actions, colours and sayings. The interactive draw‐and‐tell group recalled more correct information for items compared to the other three recall groups, without any accompanying increase in errors. We propose that drawing increases the opportunity for the interviewer to ask interactive questions, which in turn facilitates children's accurate recall of item information.

Prospective memory in an air traffic control simulation: external aids that signal when to act

At work and in our personal life we often need to remember to perform intended actions at some point in the future, referred to as Prospective Memory. Individuals sometimes forget to perform intentions in safety-critical work contexts. Holding intentions can also interfere with ongoing tasks. We applied theories and methods from the experimental literature to test the effectiveness of external aids in reducing prospective memory error and costs to ongoing tasks in an air traffic control simulation. Participants were trained to accept and hand-off aircraft and to detect aircraft conflicts. For the prospective memory task, participants were required to substitute alternative actions for routine actions when accepting target aircraft. Across two experiments, external display aids were provided that presented the details of target aircraft and associated intended actions. We predicted that aids would only be effective if they provided information that was diagnostic of target occurrence, and in this study, we examined the utility of aids that directly cued participants when to allocate attention to the prospective memory task. When aids were set to flash when the prospective memory target aircraft needed to be accepted, prospective memory error and costs to ongoing tasks of aircraft acceptance and conflict detection were reduced. In contrast, aids that did not alert participants specifically when the target aircraft were present provided no advantage compared to when no aids were used. These findings have practical implications for the potential relative utility of automated external aids for occupations where individuals monitor multi-item dynamic displays.     

A case report of compensation in daily life of a person with memory problems: detailed functional use of memory aids over a five-year period

Numerous studies have been conducted on memory aids for memory-impaired people. However, it is not known how they use these memory aids in a functional, practical way. A 20-year-old patient (MH) was monitored for five years to identify what memory aids or other means she used and how she used them to compensate for her memory problems, e.g., forgetting what was said by others in a few minutes and getting lost or turning in the wrong direction on a walk or in a building. Results indicated MH did not necessarily always use memory aids such as a notebook or calendar to compensate for her memory problems, although MH and her mother reported that she frequently used them in daily life. She coped with memory problems by using various "resources" besides the memory aid. These facts suggest that it may be necessary to redefine functionally useful compensations, which include both memory aids and resources in daily life.     

Psychologists' attitudes toward aids

Abstract

Practicing psychologists in all areas of the country will see an increasing number of persons at risk for AIDS, or with AIDS-related illnesses. Previous research has shown that AIDS elicits negative reactions from the general public and from certain health care professionals. In the current study, a national sample of randomly selected practicing psychologists completed attitude measures after reading vignettes that described a male patient with either AIDS or leukemia who was either homosexual or heterosexual. Respondents evaluated the AIDS patient more negatively and reported less willingness to interact with him in a professional role or in casual social situations. It is important to develop training and continuing education programs to prepare psychologists to deal with persons affected by AIDS.     

Cognition and hearing aids

The perceptual information transmitted from a damaged cochlea to the brain is more poorly specified than information from an intact cochlea and requires more processing in working memory before language content can be decoded. In addition to making sounds audible, current hearing aids include several technologies that are intended to facilitate language understanding for persons with hearing impairment in challenging listening situations. These include directional microphones, noise reduction, and fast-acting amplitude compression systems. However, the processed signal itself may challenge listening to the extent that with specific types of technology, and in certain listening situations, individual differences in cognitive processing resources may determine listening success. Here, current and developing digital hearing aid signal processing schemes are reviewed in the light of individual working memory (WM) differences. It is argued that signal processing designed to improve speech understanding may have both positive and negative consequences, and that these may depend on individual WM capacity.     

How forgetting aids heuristic inference

Some theorists, ranging from W. James (1890) to contemporary psychologists, have argued that forgetting is the key to proper functioning of memory. The authors elaborate on the notion of beneficial forgetting by proposing that loss of information aids inference heuristics that exploit mnemonic information. To this end, the authors bring together 2 research programs that take an ecological approach to studying cognition. Specifically, they implement fast and frugal heuristics within the ACT-R cognitive architecture. Simulations of the recognition heuristic, which relies on systematic failures of recognition to infer which of 2 objects scores higher on a criterion value, demonstrate that forgetting can boost accuracy by increasing the chances that only 1 object is recognized. Simulations of the fluency heuristic, which arrives at the same inference on the basis of the speed with which objects are recognized, indicate that forgetting aids the discrimination between the objects' recognition speeds.     

Computer aids that writers need

What problems are faced by office workers when they write documents? Are computer aids for writing available to meet their needs? These questions are answered here by: (1) describing recent research on writing processes, (2) listing various types of computer aids that either are currently marketed or are under investigation, and (3) reviewing studies that speak to the effectiveness of these aids. Numerous aids are available for problems that arise in planning, translating, and reviewing text. However, the few reported evaluation studies do not indicate that computer aids improve either the quality or the efficiency of writing.     

Anxiety's role in aids prevention

Abstract

Anxiety's role in AIDS risk reduction is discussed. We argue that behavioral techniques will be critical tools for alerting people to the threat of AIDS and their own vulnerability. Informational models have not been found to be sufficient for convincing people of the extent of the threat of AIDS to them. We suggest that techniques aimed at raising people's anxiety over their vulnerability will be necessary to raise their motivation to attend to AIDS messages, and we present techniques aimed at increasing anxiety over vulnerability. Following acknowledgment of vulnerability, people will need to adopt or continue safer sex practices that are viewed as undesirable in contrast to unsafe sex practices that are viewed as less costly and less anxiety provoking. Given a clearer practical and theoretical understanding of the anxiety-producing costs of adopting safer sex behaviors, we present methods for reducing this anxiety. We also discuss the necessity for considering ethnic, minority, and other cultural nuances in social and sexual anxiety and how these might be addressed in efforts to increase safer sex practices.     

Problem structuring aids for quantitative estimation

An important part of decision making in many contexts is the estimation of numerical values for uncertain quantities, such as the projected costs of a development project or the number of people who use illegal drugs. In previous research, estimation accuracy for such quantities was found to be improved by algorithmic decomposition. The present study examines (a) the estimation performance of individuals using extended algorithms in which component estimates are produced by multiple methods, and (b) the effectiveness of algorithms produced by individuals after receiving training in algorithmic decomposition. The extended algorithm approach yielded some improvement in estimation performance. Subjects trained in algorithmic decomposition were able to produce algorithms, the effectiveness of which were dependent upon the presence of misinformation about components of the quantity to be estimated. The results are discussed in terms of the information processing demands imposed by detailed problem structuring.     

Memory aids and the Cartesian circle

ABSTRACT

In answering the circularity charge, Descartes consistently distinguished between truths whose demonstrations we currently perceive clearly and distinctly (call these ‘C-truths’) and truths whose demonstrations we merely remember having perceived clearly and distinctly (call these ‘R-truths’). Descartes uses C-truths to prove God’s existence, thus validating R-truths. While avoiding one form of circularity (using C-truths to validate C-truths), this introduces another circle, for Descartes believes that God’s existence validates R-truths even when itself an R-truth. I consider Newman and Nelson’s grounds enhancement strategy according to which this problem is solved when God’s existence is rendered axiomatic. I argue that since it is still possible to doubt axioms when not directly apprehending them, this strategy cannot work; having to reproduce the argument for God’s existence in face of sceptical doubt is unavoidable. Drawing both on Newman and Nelson’s notion of grounds enhancement and on reproducibility interpretations, I argue that reproducibility can be enhanced via memory aids. Although discussion of memory and the Cartesian circle has been sidelined since Frankfurt’s 1962 refutation of Doney’s memory interpretation, I argue that memory is at the heart of the matter after all (though not in the same way Doney thought).

Observations with self-embedded sentences using written aids

Self-embedded sentences of any degree beyond one are permitted by the syntactic rules of English, yet previous studies report that Ss typically reject these sentences as being ungrammatical and, in addition, often cannot recover the meaning of these sentences. The present paper investigated the possibility of introducing specially structured self-embedded sentences as “aids” to the discovery of the structure of more complex self-embedded sentences. The group of Ss who received these aids performed significantly better in discovering the subject-verb and subject-object assignments in the complex sentences (many achieved perfect scores) in contrast to Ss who did not initially receive these aids (these latter Ss obtained close to the minimum possible scores).     

Route learning with augmented reality navigation aids

Current trends point towards the development and implementation of augmented reality (AR) navigation assistance systems for drivers. Previous research has found augmented reality can benefit driving performance, but the impact of AR on route learning (spatial knowledge acquisition) has received less attention. The current study used simulated driving scenarios to determine how the type of navigation aid device used (i.e., paper map, electronic map, and AR system) affected driving performance and route learning of 62 driving adults. Route learning was examined at landmark, route, and survey levels. The hypotheses tested were that AR would improve driving performance but diminish route learning compared to paper map use; and that AR would outperform electronic map use in both driving performance and route learning. Results indicated that paper map use led to poorer driving performance and greater route learning. However, map recognition may have been a confounding factor in higher level spatial knowledge acquisition with paper map use. Driving performance and route learning were similar for drivers using the electronic map and AR, but some differences suggested that drivers have reduced uncertainty and hesitation while using AR to navigate in unfamiliar areas.     

Knowing when to hear aids what to hear

Temporal preparation often has been assumed to influence motor stages of information processing. Recent studies, however, challenge this notion and provide evidence for a facilitation of visual processing. The present study was designed to investigate whether perceptual processing in the auditory domain also benefits from temporal preparation. To this end, we employed a pitch discrimination task. In Experiment 1, discrimination performance was clearly improved when participants were temporally prepared. This finding was confirmed in Experiment 2, which ruled out possible influences of short-term memory. The results support the notion that temporal preparation enhances perceptual processing not only in the visual, but also in the auditory, modality.
