This chapter considers what mental actions are, and how they are best explained. Mental actions are shown to include mental rehearsal of actions, prospective imagining, inner speech, attention, memory search, and (perhaps surprisingly) the spontaneous thoughts that occur while mind-wandering, as well as creative ideas that seemingly occur to one “out of the blue.” The chapter also discusses how controlled sequences of mental action can be explained, and discusses events like judgments and decisions that armchair-philosophers have been apt to claim are mental actions, but really are not.
Attention is critical to our daily lives, from simple acts of reading or listening to a conversation to the more demanding situations of trying to concentrate in a noisy environment or driving on a busy roadway. This book offers a concise introduction to the science of attention, featuring real-world examples and fascinating studies of clinical disorders and brain injuries. It introduces cognitive neuroscience methods and covers the different types and core processes of attention. The links between attention, perception, and action are explained, along with exciting new insights into the brain mechanisms of attention revealed by cutting-edge research. Learning tools – including an extensive glossary, chapter reviews, and suggestions for further reading – highlight key points and provide a scaffolding for use in courses. This book is ideally suited for graduate or advanced undergraduate students as well as for anyone interested in the role attention plays in our lives.
Exposure to adversity during the perinatal period has been associated with cognitive difficulties in children. Given the role of the nucleus accumbens (NAcc) in attention and impulsivity, we examined whether NAcc volume at age six mediates the relations between pre- and postnatal adversity and subsequent attention problems in offspring. 306 pregnant women were recruited as part of the Growing Up in Singapore Towards Healthy Outcomes Study. Psychosocial stress was assessed during pregnancy and across the first 5 years postpartum. At six years of age, children underwent structural MRI and, at age seven years, mothers reported on their children’s attention problems. Separate factor analyses conducted on measures of pre- and postnatal adversity each yielded two latent factors: maternal mental health and socioeconomic status. Both pre- and postnatal maternal mental health predicted children’s attention difficulties. Further, NAcc volume mediated the relation between prenatal, but not postnatal, maternal mental health and children’s attention problems. These findings suggest that the NAcc is particularly vulnerable to prenatal maternal mental health challenges and contributes to offspring attention problems. Characterizing the temporal sensitivity of neurobiological structures to adversity will help to elucidate mechanisms linking environmental exposures and behavior, facilitating the development of neuroscience-informed interventions for childhood difficulties.
Scopolamine is a muscarinic receptor antagonist and is widely utilized as a “memory-loss model.” However, its impact across different memory and attention tasks and using different modes of administration has yet to be clearly evaluated. This systematic review and meta-analysis investigates the effect of scopolamine, across all routes of administration and across different dosages, on memory and attention performance in healthy humans (PROSPERO ID: CRD42024531634).
Methods
Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, we searched (on 20 April 2024) for studies that utilized scopolamine and assessed memory and/or attention. Random-effects meta-analyses were conducted across a range of memory and attention tasks using “Comprehensive Meta-Analysis,” Version 3, to evaluate differential pharmacological effects on cognitive tasks between the scopolamine and placebo groups.
Results
Forty-six studies fulfilled the inclusion and exclusion criteria. Scopolamine negatively impaired performance on all memory tasks (immediate memory, delayed recall, digit span, Buschke selective reminding task, and recognition memory) and led to slower reaction times for three of the five attention tasks examined (choice reaction time, simple reaction time, and rapid visual information processing) compared to placebo. Scopolamine’s negative effect on memory and attention was greater with injectable (e.g., intramuscular, intravenous, and subcutaneous) compared to non-injectable routes of administration (e.g., intranasal, oral, and transdermal).
Conclusion
This study supports the use of scopolamine as a “memory-loss model,” particularly when given by an injectable route of administration. Future clinical trials should evaluate the bioavailability of scopolamine across different routes of administration to ensure therapeutic benefits outweigh any potential adverse cognitive effects.
We investigate the role of visual attention in risky choice in a rich experimental dataset that includes eye-tracking data. We first show that attention is not reducible to individual and contextual variables, which explain only 20% of attentional variation. We then decompose attentional variation into individual average attention and trial-wise deviations of attention to capture different cognitive processes. Individual average attention varies by individual, and can proxy for individual preferences or goals (as in models of “rational inattention” or goal-directed attention). Trial-wise deviations of attention vary within subjects and depend on contextual factors (as in models of “salience” or stimulus-driven attention). We find that both types of attention predict behavior: average individual attention patterns are correlated with individual levels of loss aversion and capture part of this individual heterogeneity. Adding trial-wise deviations of attention further improves model fit. Our results show that a decomposition of attention into individual average attention and trial-wise deviations of attention can capture separable cognitive components of decision making and provides a useful tool for economists and researchers from related fields interested in decision-making and attention.
There is a longstanding belief amongst scholars of psychophysiology that activation is positively associated with attention. However, recent work on news avoidance suggests that activation from negative content is linked to decreased attention. The current study seeks to investigate these different expectations and suggests that both increased and decreased activation can be linked to both attention and avoidance. Using an experiment that employs skin conductance levels and heart rate to evaluate subjects’ media selection choices, the author finds that even as deactivation is most likely to precede the decision to turn away from content, roughly 30% of the time activation precedes turning away. These findings confirm prior conclusions from the psychophysiological communications literature, and in the news avoidance literature, but it also highlights the need for more nuanced expectations where activation and media selection are concerned.
This chapter reviews the principle domains assessed by clinical neuropsychologists when conducting a cognitive assessment and the utility of assessment in diagnosis and clinical management. It provides an overview of methods for estimating prior functioning, the non-specific nature of patients’ subjective neurological complaints, validity and base rate issues, and some of the difficulties and complicating issues that arise when interpreting neuropsychological data. Those interested in succinct summaries of clinical presentations and “bedside” measures may find Hodges [1] and Larner [2] useful further reading, and those interested in detailed reviews of cognitive tests can do no better than to consult Lezak, Howieson, Bigler and Tranel’s [3] authoritative text.
Sustained attention is integral to goal-directed tasks in everyday life. It is a demanding and effortful process prone to failure. Deficits are particularly prevalent in mood disorders. However, conventional methods of assessment, rooted in overall measures of performance, neglect the nuanced temporal dimensions inherent in sustained attention, necessitating alternative analytical approaches.
Methods
This study investigated sustained attention deficits and temporal patterns of attentional fluctuation in a large clinical cohort of patients with bipolar depression (BPd, n = 33), bipolar euthymia (BPe, n = 84), major depression (MDd, n = 38) and controls (HC, n = 138) using a continuous performance task (CPT). Longitudinal and spectral analyses were employed to examine trial-level reaction time (RT) data.
Results
Longitudinal analysis revealed a significant worsening of performance over time (vigilance decrement) in BPd, whilst spectral analysis unveiled attentional fluctuations concentrated in the frequency range of 0.077 Hz (1/12.90 s)–0.049 Hz (1/20.24 s), with BPd and MDd demonstrating greater spectral power compared to BPe and controls.
Conclusions
Although speculative, the increased variability in this frequency range may have an association with the dysfunctional activity of the Default Mode Network, which has been shown to oscillate at a similar timescale. These findings underscore the importance of considering the temporal dimensions of sustained attention and show the potential of spectral analysis of RT in future clinical research.
Barbara Rogoff reflects on the sources and pathway of her work on understanding culture and individual learning as aspects of a mutually constituting process. She describes her efforts across decades to convey the idea that learning is a process of transforming one’s participation in cultural communities, which simultaneously contributes to transforming and maintaining the communities’ cultural practices. As ways of getting traction on understanding and researching from the mutually constituting perspective, Rogoff offers the metaphors of lenses that bring aspects of the overall process into focus, and fractals that aid in seeing the similarity of cultural patterns across both small moments and generations. She connects these ideas with several concepts and lines of research that she and her colleagues have contributed: everyday cognition, guided participation, Learning by Observing and Pitching In (LOPI) to family and community endeavors, interdependence with autonomy, collaborative initiative, simultaneous attention, fluid collaboration, and “Barbara’s do-do theory.”
This chapter reviews changes to cognition with age. This includes sections on attention, executive function, motor control, and language. After reviewing cognitive aging and these basic cognitive functions, the chapter considers the burgeoning literature on training cognitive ability with age. This section includes review of intervention programs focused on physical activity, mediation and mediation, cognitive activities, working memory training, and long-term memory training.
Iconicity facilitates learning signs, but it is unknown whether recognition of meaning from the sign form occurs automatically. We recorded ERPs to highly iconic (transparent) and non-iconic ASL signs presented to one group who knew they would be taught signs (learners) and another group with no such expectations (non-learners). Participants watched sign videos and detected an occasional grooming gesture (no semantic processing required). Before sign onset, learners showed a greater frontal negativity compared to non-learners for both sign types, possibly due to greater motivation to attend to signs. During the N400 window, learners showed greater negativity to iconic than non-iconic signs, indicating more semantic processing for iconic signs. The non-learners showed a later and much weaker iconicity effect. The groups did not differ in task performance or in P3 amplitude. We conclude that comprehending the form-meaning mapping of highly iconic signs is not automatic and requires motivation and attention.
This Element examines the influence of expectation and attention on conscious perception. It explores the debate on whether attention is necessary for conscious perception by presenting empirical evidence from studies on inattentional blindness, change blindness, and the attentional blink. While the evidence strongly suggests that attention is necessary for conscious perception, other research has shown that expectation can shape perception, sometimes leading to illusory experiences where predicted stimuli are perceived despite their absence. This phenomenon, termed 'expectation awareness', suggests that attention may not be necessary for all conscious experiences. These findings are explored within the predictive processing framework, where the brain is characterized as a prediction engine, continuously updating its internal models to minimize prediction errors. Integrating findings from psychology, neuroscience, and cognitive science, this Element provides a predictive processing model of how attention and expectation construct perceptual reality. It also discusses clinical and theoretical implications and suggests future research.
The eight dimensions of being with, outlined in detail in my A Nazareth Manifesto and elsewhere in their missiological, ethical and public policy implications, are here explored in their full scriptural dimensions. Presence, attention, mystery, delight, participation, partnership, enjoyment and glory each have profound resonances in Old and New Testaments, and each provides a continuous thread through incarnation, the reason for creation, the nature of Jesus’ ministry and death, the work of the Holy Spirit, the church and heavenly destiny – in relation to God, to one another and to the whole creation. They affirm how the incarnation is not a means to an end (such as saving us from our sins) but an end in itself, and they expand the notion of being with into a multidimensional concept with rich resonances.
Mean levels of cognitive functioning typically do not show an association with self-reported cognitive fatigue in persons with multiple sclerosis (PwMS), but some studies indicate that cognitive variability has an association with cognitive fatigue. Additionally, coping has been shown to be a powerful moderator of some outcomes in multiple sclerosis (MS). To date, however, coping has not been considered as a possible moderator of the relationship between cognitive fatigue and cognitive variability in MS. The current study examined this relationship.
Method:
We examined 52 PwMS. All participants were administered the Fatigue Impact Scale, the Coping Orientation to Problems Experienced Questionnaire, and cognitive tests. Indices of variability for memory and attention/executive functioning tests were used as outcome variables. Avoidant coping, active coping, and composite coping indices were used as moderators.
Results:
The interaction analyses for the avoidant coping and composite coping indices were significant and accounted for 8 and 11% of the attention/executive functioning variability outcome, respectively. The interactions revealed that at low levels of cognitive fatigue, attention/executive functioning variability was comparable between the low and high avoidant and composite coping groups. However, at high levels of cognitive fatigue, PwMS using lower levels of avoidant coping (less maladaptive coping) showed less variable attention/executive functioning scores compared with those using higher levels of avoidant coping. We found a similar pattern for the composite coping groups.
Conclusion:
At high levels of cognitive fatigue, PwMS using adaptive coping showed less attention/executive functioning variability. These findings should be considered in the context of treatment implications.
A survey of instruction delivery and reinforcement methods in recent laboratory experiments reveals a wide and inconsistently reported variety of practices and limited research evaluating their effectiveness. Thus, we experimentally compare how methods of delivering and reinforcing experiment instructions impact subjects’ comprehension and retention of payoff-relevant information. We report a one-shot individual decision task in which non-money-maximizing behavior can be unambiguously identified and find that such behavior is prevalent in our baseline treatment which uses plain, but relatively standard experimental instructions. We find combinations of reinforcement methods that can eliminate half of non-money-maximizing behavior, and we find that we can induce a similar reduction via enhancements to the content of instructions. Residual non-money-maximizing behavior suggests that this may be an important source of noise in experimental studies.
When making decisions, people tend to look back and forth between the alternatives until they eventually make a choice. Eye-tracking research has established that these shifts in attention are strongly linked to choice outcomes. A predominant framework for understanding the dynamics of the choice process, and thus the effects of attention, is sequential sampling of information. However, existing methods for estimating the attention parameters in these models are computationally costly and overly flexible, and yield estimates with unknown precision and bias. Here we propose an estimation method that relies on a link between sequential sampling models and random utility models (RUM). This method uses familiar econometric tools (i.e., logistic regression) and yields estimates that appear to be unbiased and relatively precise compared to existing methods, in a small fraction of the computation time. The RUM thus appears to be a useful tool for estimating the effects of attention on choice.
This chapter adopts an Anthropocene framework to contextualize Gerard Manley Hopkins. Placing his work within the epoch of human geophysical agency, I argue, affords new perspective on his radical contribution as an ecological witness. It allows us to see that Hopkins’s depictions of natural entities involved an intuition about their embeddedness in larger systems, many inchoately explained by contemporary science; that his representations of non-human nature seldom avoided the ‘anthropos’ (the ‘human’ in Anthropocene), whether as destructive interloper or divinely privileged steward; and that his life and work included moments of prescience about human activity interfering with Earth-system processes. To recontextualize Hopkins thus is to furnish different ways to interpret his work (in wider conceptual networks and deeper time horizons) and to animate that work’s reception (in light of present concerns). It is also to affiliate Hopkins with ecopoets whose formal innovations might be fruitfully juxtaposed with his poetics.
This article argues that our attention is pervasively biased by embodied affects and that we are normatively assessable in light of this. From a contemporary perspective, normative theorizing about attention is a relatively new trend (Siegel 2017: Ch. 9, Irving 2019, Bommarito 2018: Ch. 5). However, Buddhist philosophy has provided us with a well-spring of normatively rich theorizing about attention from its inception. This article will address how norms of attention are dealt with in Buddhaghosa’s (5th-6th CE) claims about how wholesome forms of empathy can go wrong. Through this analysis, I will show that Buddhist philosophers like Buddhaghosa think there is an existential norm of attention, one that commands us not just to pay attention to ourselves and the world properly, but one whereby we are exhorted to attend to ourselves in a way that gradually transforms our cognitive-emotional constitution so that we become liberated from suffering.
Climate models are biased with respect to real-world observations. They usually need to be adjusted before being used in impact studies. The suite of statistical methods that enable such adjustments is called bias correction (BC). However, BC methods currently struggle to adjust temporal biases. Because they mostly disregard the dependence between consecutive time points. As a result, climate statistics with long-range temporal properties, such as the number of heatwaves and their frequency, cannot be corrected accurately. This makes it more difficult to produce reliable impact studies on such climate statistics. This article offers a novel BC methodology to correct temporal biases. This is made possible by rethinking the philosophy behind BC. We will introduce BC as a time-indexed regression task with stochastic outputs. Rethinking BC enables us to adapt state-of-the-art machine learning (ML) attention models and thereby learn different types of biases, including temporal asynchronicities. With a case study of number of heatwaves in Abuja, Nigeria and Tokyo, Japan, we show more accurate results than current climate model outputs and alternative BC methods.
It is believed that the attentional engagement of language learners may reinforce deeper neuronal processing and promote later retrieval. To address language learners’ needs and facilitate language learning, we used audio-visual entertainment (AVE) and cranio-electro stimulation (CES), in addition to multisensory-based instruction, to modify attention and retention processes. Thus, we taught a set of words with the common procedure of audio-visual instruction to 32 English language learners in the control group, CES, and AVE sessions. However, they received five sensory involvements (i.e., auditory, visual, tactile, olfactory, and gustatory) for the target words in the multisensory session. Following each instruction, a pragmatic-Stroop task and a true/false test were conducted to examine the subjects’ attention and retention processes, respectively. Analyzing the response times acquired from the pragmatic-Stroop task, it was found that multisensory-based instruction led to quicker responses in comparison to the audio-visual method preceded by AVE and CES stimulations. The response accuracy results from the retention test also revealed that the subjects provided more accurate responses to the words taught during the multisensory session. The implication is that the enriched multisensory inputs can improve L2 learners’ mental agility and facilitate successful retention and retrieval of information after a short interval period.
