Prospective memory training in older adults and its relevance for successful aging

In research on cognitive plasticity, two training approaches have been established: (1) training of strategies to improve performance in a given task (e.g., encoding strategies to improve episodic memory performance) and (2) training of basic cognitive processes (e.g., working memory, inhibition) that underlie a range of more complex cognitive tasks (e.g., planning) to improve both the training target and the complex transfer tasks. Strategy training aims to compensate or circumvent limitations in underlying processes, while process training attempts to augment or to restore these processes. Although research on both approaches has produced some promising findings, results are still heterogeneous and the impact of most training regimes for everyday life is unknown. We, therefore, discuss recent proposals of training regimes aiming to improve prospective memory (i.e., forming and realizing delayed intentions) as this type of complex cognition is highly relevant for independent living. Furthermore, prospective memory is associated with working memory and executive functions and age-related decline is widely reported. We review initial evidence suggesting that both training regimes (i.e., strategy and/or process training) can successfully be applied to improve prospective memory. Conceptual and methodological implications of the findings for research on age-related prospective memory and for training research in general are discussed.     

Know thy sound: Perceiving self and others in musical contexts

This review article provides a summary of the findings from empirical studies that investigated recognition of an action's agent by using music and/or other auditory information. Embodied cognition accounts ground higher cognitive functions in lower level sensorimotor functioning. Action simulation, the recruitment of an observer's motor system and its neural substrates when observing actions, has been proposed to be particularly potent for actions that are self-produced. This review examines evidence for such claims from the music domain. It covers studies in which trained or untrained individuals generated and/or perceived (musical) sounds, and were subsequently asked to identify who was the author of the sounds (e.g., the self or another individual) in immediate (online) or delayed (offline) research designs. The review is structured according to the complexity of auditory–motor information available and includes sections on: 1) simple auditory information (e.g., clapping, piano, drum sounds), 2) complex instrumental sound sequences (e.g., piano/organ performances), and 3) musical information embedded within audiovisual performance contexts, when action sequences are both viewed as movements and/or listened to in synchrony with sounds (e.g., conductors' gestures, dance). This work has proven to be informative in unraveling the links between perceptual–motor processes, supporting embodied accounts of human cognition that address action observation. The reported findings are examined in relation to cues that contribute to agency judgments, and their implications for research concerning action understanding and applied musical practice.     

Information learned from generic language becomes central to children’s biological concepts: Evidence from their open-ended explanations

Generic sentences (e.g., “Snakes have holes in their teeth”) convey that a property (e.g., having holes in one’s teeth) is true of a category (e.g., snakes). We test the hypothesis that, in addition to this basic aspect of their meaning, generic sentences also imply that the information they express is more conceptually central than the information conveyed in similar non-generic sentences (e.g., “This snake has holes in his teeth”). To test this hypothesis, we elicited 4- and 5-year-old children’s open-ended explanations for generic and non-generic versions of the same novel properties. Based on arguments in the categorization literature, we assumed that, relative to more peripheral properties, properties that are understood as conceptually central would be explained more often as causes and less often as effects of other features, behaviors, or processes. Two experiments confirmed the prediction that preschool-age children construe novel information learned from generics as more conceptually central than the same information learned from non-generics. Additionally, Experiment 2 suggested that the conceptual status of novel properties learned from generic sentences becomes similar to that of familiar properties that are already at the category core. These findings illustrate the power of generic language to shape children’s concepts.     

Boundary extension: Findings and theories

A view of a scene is often remembered as containing information that might have been present just beyond the actual boundaries of that view, and this is referred to as boundary extension. Characteristics of the view (e.g., scene or nonscene; close-up or wide-angle; whether objects are cropped, static, or in motion, emotionally neutral or emotionally charged), display (e.g., aperture shape and size; target duration; retention interval; whether probes of memory involve magnification/minification or change in physical distance), and observer (e.g., allocation of attention; age; planned fixation, gaze direction, and eye movements; monocular or binocular viewing; prior exposure; neurological correlates) that influence boundary extension are reviewed. Proposed mechanisms of boundary extension (perceptual, memory, or motion schema; extension–normalization; attentional selection; errors in source monitoring) are discussed, and possible relationships of boundary extension to other cognitive processes (e.g., representational momentum; remembered distance and remembered size; amodal completion; transsaccadic memory) are briefly addressed.     

Spontaneous versus Controlled Influences of Stimulus-Based Affect on Choice Behavior

This article identifies two routes through which affect and cognitions arising from a stimulus can influence choices: a “lower order” route, where choices are influenced through automatic affective processes, and a “higher order” route, where choices are influenced through more controlled affective or consequence-related cognitive processes. Across three experiments the extent of deliberation, mental preoccupation, and the nature of exposure to the stimuli were manipulated to identify conditions under which lower order affect, higher order affect, or higher order cognitions impact choices. Respondents chose between two alternatives: one that was associated with more intense positive affect but less favorable cognitions (e.g., chocolate cake), and one that was associated with less intense positive affect but more favorable cognitions (e.g., fruit salad). Findings suggest that when the individual makes the decision quickly and is mentally preoccupied while making the decision, choices are driven by lower order affect. When the individual deliberates on the decision without being mentally preoccupied and the affect-laden option is in full view while the decision is being deliberated upon, choices are driven by higher order affect. In both cases, the affect-laden option (e.g. chocolate cake) is selected. In all other situations, choices are driven by higher order consequence-related cognitions and the alternative that is superior on the cognitive dimension (e.g. fruit salad) is selected. It is suggested that the effects of affective reactions on choice occur through the activation of appetitive (i.e., gratification-seeking) goals.     

Phenomenological features of dreams: Results from dream log studies using the Subjective Experiences Rating Scale (SERS)

Self-ratings of dream experiences were obtained from 144 college women for 788 dreams, using the Subjective Experiences Rating Scale (SERS). Consistent with past studies, dreams were characterized by a greater prevalence of vision, audition, and movement than smell, touch, or taste, by both positive and negative emotion, and by a range of cognitive processes. A Principal Components Analysis of SERS ratings revealed ten subscales: four sensory, three affective, one cognitive, and two structural (events/actions, locations). Correlations (Pearson r) among subscale means showed a stronger relationship among the process-oriented features (sensory, cognitive, affective) than between the process-oriented and content-centered (structural) features—a pattern predicted from past research (e.g., Bulkeley & Kahan, 2008). Notably, cognition and positive emotion were associated with a greater number of other phenomenal features than was negative emotion; these findings are consistent with studies of the qualitative features of waking autobiographical memory (e.g., Fredrickson, 2001).     

The need for affect: individual differences in the motivation to approach or avoid emotions

The present research developed and tested a new individual-difference measure of the need for affect, which is the motivation to approach or avoid emotion-inducing situations. The first phase of the research developed the need for affect scale. The second phase revealed that the need for affect is related to a number of individual differences in cognitive processes (e.g., need for cognition, need for closure), emotional processes (e.g., affect intensity, repression-sensitization), behavioral inhibition and activation (e.g., sensation seeking), and aspects of personality (Big Five dimensions) in the expected directions, while not being redundant with them. The third phase of the research indicated that, compared to people low in the need for affect, people high in the need for affect are more likely to (a) possess extreme attitudes across a variety of issues, (b) choose to view emotional movies, and (c) become involved in an emotion-inducing event (the death of Princess Diana). Overall, the results indicate that the need for affect is an important construct in understanding emotion-related processes.     

The do re mi's of everyday life: the structure and personality correlates of music preferences

The present research examined individual differences in music preferences. A series of 6 studies investigated lay beliefs about music, the structure underlying music preferences, and the links between music preferences and personality. The data indicated that people consider music an important aspect of their lives and listening to music an activity they engaged in frequently. Using multiple samples, methods, and geographic regions, analyses of the music preferences of over 3,500 individuals converged to reveal 4 music-preference dimensions: Reflective and Complex, Intense and Rebellious, Upbeat and Conventional, and Energetic and Rhythmic. Preferences for these music dimensions were related to a wide array of personality dimensions (e.g., Openness), self-views (e.g., political orientation), and cognitive abilities (e.g., verbal IQ).     

Cognitive psychology in sport: Progress and prospects

ProblemThere has been a recent upsurge of research interest in cognitive sport psychology or the scientific study of mental processes (e.g., mental imagery) in athletes. Despite this interest, an important question has been neglected. Specifically, is research on cognitive processes in athletes influential outside sport psychology, in the “parent” field of cognitive psychology or in the newer discipline of cognitive neuroscience?ObjectivesThe purpose of this paper is to explore the theoretical significance of research on expertise, attention and mental imagery in athletes from the perspective of cognitive psychology and cognitive neuroscience.MethodFollowing analysis of recent paradigm shifts in cognitive psychology and cognitive neuroscience, a narrative review is provided of key studies on expertise, attention and mental imagery in athletes.Results and conclusionsThis paper shows that cognitive sport psychology has contributed significantly to theoretical understanding of certain mental processes studied in cognitive psychology and cognitive neuroscience. It also shows that neuroscientific research on motor imagery can benefit from increased collaboration with cognitive sport psychology. Overall, I conclude that the domain of sport offers cognitive researchers a rich and dynamic natural laboratory in which to study how the mind works.     

Anatomic and environmental dimensions of stimulus-response compatibility: implication for theories of memory coding.

Reaction time was higher when the relation between stimulus location and anatomic hand was reversed (e.g., left light-right hand) rather than direct (e.g., left light-left hand), even though the environmental location of the hand (up or down) was unrelated to the location of the stimulus (left or right). This effect was shown to be due primarily to decision processes, rather than to interhemisphere transfer delay. This result does not support the view that long-term memory for responses encodes environmental but not anatomic dimensions.     

Children expect generic knowledge to be widely shared

The ability to acquire and store generic information (that is, information about entire categories) is at the core of human cognition. Remarkably, even young children place special value on generic information, often inferring that it holds important insights about the world. Here, we tested whether children's assumptions about the nature of generic information guide their expectations about how widely known this information is. Across four experiments, 4- to 7-year-old children (N=192) were presented with novel facts in either generic (e.g., "Hedgehogs eat hexapods") or non-generic (e.g., "This hedgehog eats hexapods") format and were asked whether other people (e.g., their moms, grown-ups in general) knew these facts. Overall, children were more likely to say that others knew the generic than the non-generic facts. In addition to highlighting the centrality of generic knowledge in early cognitive life, children's assumption that generic facts are widely known has implications for their social cognition and academic achievement, as well as for the process of language acquisition.     

The effect of generic statements on children's causal attributions: questions of mechanism

Generic statements, or generics, express generalizations about entire kinds (e.g., "Girls are good at a game called 'tooki'"). In contrast, nongeneric statements express facts about specific (sets of) individuals (e.g., "Jane is good at tooki"). Aside from simply conveying information, generics and nongenerics also instill different causal perspectives on the facts expressed, implying that these facts stem from deep, inherent causes (e.g., talent) or from external, mechanistic causes (e.g., instruction), respectively. In the present research (with samples of 4- to 7-year-olds and undergraduates, N = 220), we proposed that children's causal attributions for the facts learned through these statements are determined not by the generic/nongeneric format of the statements themselves but rather by the generic/nongeneric format of the beliefs relevant to these statements. This proposal led to two specific predictions. First, the influence of the generic belief induced by a novel generic statement should be detected in any subsequent context that falls under its scope--even in circumstances that involve particular individuals. Confirming this prediction, participants often attributed a fact conveyed in a nongeneric statement (e.g., a particular girl's tooki ability) to deep, inherent causes if they had previously formed a relevant generic belief (e.g., by hearing that girls are good at tooki). Second, we predicted that nongeneric statements such as "Most girls are good at tooki" should also promote attributions to deep causes because they often ultimately give rise to generic beliefs, as suggested by recent evidence. This prediction was confirmed as well. These results clarify and expand our knowledge of the influence of language on children's understanding of the world.

On the primacy of the brain

It is well established that emotion is a product of complex interactions among the biological subsystems of the organism. The human nervous system must play a fundamental role in organizing and controlling the manifestation of these interactions. Since emotional disturbance is one of the major phenomena underlying maladaptive behavior, a solid understanding of its nature and mechanisms is essential for enhancing therapeutic practices. Although an increasing number of scholars now advocate the notion of the dependence of emotion on antecedent cognitive processes (e.g., Lazarus, 1982, 1984), and the relevance of both central and peripheral processes of the nervous system to emotional behavior (e.g., Panksepp, 1988; Pribram, 1984), Zajonc (1984) views emotion as independent of cognitive processes. This paper provides a critical evaluation of the basis of Zajonc’s (1984) argument from a neurobiological and psychotherapeutic point of view.     

Loss of Cells—Loss of Self: Frontotemporal Lobar Degeneration and Human Emotion

ABSTRACT— Frontotemporal lobar degeneration (FTLD) is a devastating disease that profoundly changes emotion, self, and personality while initially sparing many aspects of cognitive functioning. This article reviews research that applies methods from basic affective science to obtain a more precise view of FTLD's impact on emotional functioning. This research indicates that simple forms of emotional reactivity are relatively preserved in the early stages of the disease. In contrast, more complex emotional processes, such as those involved with self-conscious emotions (e.g., embarrassment), emotion regulation, and recognizing emotions in others, are severely impaired. FTLD provides rich opportunities for increasing our understanding of the nature of emotion and of the emotional and social brain.

认知加工的自动化现象：从二分法到渐进观

认知自动化是人类学习和进步的必经之路。传统的二分法通过无意识等特征简单地将认知加工过程分为受控加工与自动化加工。但这些特征取决于研究者所采用的研究范式, 不具有普适性。近年来研究者根据注意资源有限理论提出自动化是一个渐进的过程, 而注意资源需求的减少是自动化发展的核心特征。相比二分法, 这种渐进观更加符合实证研究的发现。而且, 渐进观在信息加工自动化理论和技能习得理论的阶段性中都得以体现, 进一步证明了渐进观的普适性。     

Resource depletion does not influence prospective memory in college students

This paper reports an experiment designed to investigate the potential influence of prior acts of self-control on subsequent prospective memory performance. College undergraduates (n = 146) performed either a cognitively depleting initial task (e.g., mostly incongruent Stroop task) or a less resource-consuming version of that task (e.g., all congruent Stroop task). Subsequently, participants completed a prospective memory task that required attentionally demanding monitoring processes. The results demonstrated that prior acts of self-control do not impair the ability to execute a future intention in college-aged adults. We conceptually replicated these results in three additional depletion and prospective memory experiments. This research extends a growing number of studies demonstrating the boundary conditions of the resource depletion effect in cognitive tasks.     

Multinomial models reveal deficits of two distinct controlled retrieval processes in aging and very mild Alzheimer disease

Dual-process models of episodic retrieval reveal consistent deficits of controlled recollection in aging and Alzheimer disease (AD). In contrast, automatic familiarity is relatively spared. We extend standard dual-process models by showing the importance of a third capture process. Capture produces a failure to attempt recollection, which might reflect a distinct error from an inability to recollect when attempted (Jacoby et al. Journal of Experimental Psychology: General, 134(2), 131–148, 2005a). We used multinomial process tree (MPT) modeling to estimate controlled recollection and capture processes, as well as automatic retrieval processes, in a large group of middle-aged to older adults who were cognitively normal (N = 519) or diagnosed with the earliest detectable stage of AD (N = 107). Participants incidentally encoded word pairs (e.g., knee bone). At retrieval, participants completed cued word fragments (e.g., knee b_n_) with primes that were congruent (e.g., bone), incongruent (e.g., bend), or neutral (i.e., &&&) to the target (e.g., bone). MPT models estimated retrieval processes both at the group and the individual levels. A capture parameter was necessary to fit MPT models to the observed data, suggesting that dual-process models of this task can be contaminated by a capture process. In both group- and individual-level analyses, aging and very mild AD were associated with increased susceptibility to capture, decreased recollection, and no differences in automatic influences. These results suggest that it is important to consider two distinct modes of attentional control when modeling retrieval processes. Both forms of control (recollection and avoiding capture) are particularly sensitive to cognitive decline in aging and early-stage AD.
