Modes Of Information Processing Research Articles

Synergistic information supports modality integration and flexible learning in neural networks solving multiple tasks.

Striking progress has been made in understanding cognition by analyzing how the brain is engaged in different modes of information processing. For instance, so-called synergistic information (information encoded by a set of neurons but not by any subset) plays a key role in areas of the human brain linked with complex cognition. However, two questions remain unanswered: (a) how and why a cognitive system can become highly synergistic; and (b) how informational states map onto artificial neural networks in various learning modes. Here we employ an information-decomposition framework to investigate neural networks performing cognitive tasks. Our results show that synergy increases as networks learn multiple diverse tasks, and that in tasks requiring integration of multiple sources, performance critically relies on synergistic neurons. Overall, our results suggest that synergy is used to combine information from multiple modalities-and more generally for flexible and efficient learning. These findings reveal new ways of investigating how and why learning systems employ specific information-processing strategies, and support the principle that the capacity for general-purpose learning critically relies on the system's information dynamics.

Involvement of the claustrum in the cortico-basal ganglia circuitry: connectional study in the non-human primate

The claustrum is an ancient telencephalic subcortical structure displaying extensive, reciprocal connections with much of the cortex and receiving projections from thalamus, amygdala, and hippocampus. This structure has a general role in modulating cortical excitability and is considered to be engaged in different cognitive and motor functions, such as sensory integration and perceptual binding, salience-guided attention, top-down executive functions, as well as in the control of brain states, such as sleep and its interhemispheric integration. The present study is the first to describe in detail a projection from the claustrum to the striatum in the macaque brain. Based on tracer injections in different striatal regions and in different cortical areas, we observed a rough topography of the claustral connectivity, thanks to which a claustral zone projects to both a specific striatal territory and to cortical areas involved in a network projecting to the same striatal territory. The present data add new elements of complexity of the basal ganglia information processing mode in motor and non-motor functions and provide evidence for an influence of the claustrum on both cortical functional domains and cortico-basal ganglia circuits.

Electrophysiological Properties of Proprioception-Related Neurons in the Intermediate Thoracolumbar Spinal Cord.

Proprioception, the sense of limb and body position, is required to produce accurate and precise movements. Proprioceptive sensory neurons transmit muscle length and tension information to the spinal cord. The function of excitatory neurons in the intermediate spinal cord, which receive this proprioceptive information, remains poorly understood. Using genetic labeling strategies and patch-clamp techniques in acute spinal cord preparations in mice, we set out to uncover how two sets of spinal neurons, Clarke's column (CC) and Atoh1-lineage neurons, respond to electrical activity and how their inputs are organized. Both sets of neurons are located in close proximity in laminae V-VII of the thoracolumbar spinal cord and have been described to receive proprioceptive signals. We find that a majority of CC neurons have a tonic-firing type and express a distinctive hyperpolarization-activated current (Ih). Atoh1-lineage neurons, which cluster into two spatially distinct populations, are mostly a fading-firing type and display similar electrophysiological properties to each other, possibly due to their common developmental lineage. Finally, we find that CC neurons respond to stimulation of lumbar dorsal roots, consistent with prior knowledge that CC neurons receive hindlimb proprioceptive information. In contrast, using a combination of electrical stimulation, optogenetic stimulation, and transsynaptic rabies virus tracing, we find that Atoh1-lineage neurons receive heterogeneous, predominantly local thoracic inputs that include parvalbumin-lineage sensory afferents and local interneuron presynaptic inputs. Altogether, we find that CC and Atoh1-lineage neurons have distinct membrane properties and sensory input organization, representing different subcircuit modes of proprioceptive information processing.

Green consumption by design: interaction experiences and customization intentions

PurposeThis study investigated the impacts of the interaction experiential customization (IEC) mode on consumers' information processing fluency and green customization intention (GCI) as well as the moderating effect of consumers' self-construal.Design/methodology/approachThis study conducted an online field experiment, questionnaire study and between-subjects laboratory experiment to test the hypotheses.FindingsIt was found that IEC had a significant positive effect on consumers' GCI. Moreover, consumer retrieval processing fluency played a partial mediating role in the relationship between IEC and GCI. In addition, consumers' self-construal moderated the “IEC? Three dimensions of processing fluency” relationships.Practical implicationsThe results emphasized the importance of IEC in influencing consumers' consumption intention in a green customization setting and have some practical implications, that is, companies have the opportunity to use appropriate digital choice architecture designs, which can enhance consumer processing fluency when promoting eco-friendly products in the customized consumption process, especially for independent consumers.Originality/valueThis study focused on the customization design on consumers' GCI and explained the mechanism of impact of IEC on improving consumers' processing fluency and GCI in a product customization setting based on the fluency theory. In addition, this study investigated the moderating effect of consumers' self-construal (independent vs interdependent) on their significant different information processing modes for low-carbon choices.

Matching Crisis Event With Destination Response Strategy

A conceptual model is tested across four studies that examine how tourist destination crisis types (external/internal) impact the information processing mode (heuristic/systematic), internal state (empathy/animosity), and boycott intentions of tourists. The matching effect between destination crisis event type and response strategy (defensive/accommodative) are also examined. Results suggest that internally attributed destination crisis events may be more likely to lead to boycott, and tourists tend to employ a heuristic information processing mode for externally attributed crises but a systematic mode for internally attributed crises. The matching effect of destination crisis type with response strategy indicated that a defensive (accommodative) strategy may effectively weaken the negative effects of externally (internally) attributed crises. Discerning the nature and perceived causes of crisis events offers a means to pinpoint approaches for guiding response strategies to mitigate the likelihood of boycotts and inform effective strategies for handling a destination crisis.

EXTENDING TASK-TECHNOLOGY FIT WITH DUAL INFORMATION PROCESSING MODES IN DISASTER DECISION SUPPORT

ABSTRACT Leveraging the analytic and heuristic modes of information processing (i.e. the dual information processing modes) equips disaster professionals with valuable insights into decision support processes during a disaster. Drawing from task-technology fit (TTF), we explore the fit between the dual information processing modes and the influence of different task conditions on perceived disaster decision support by conducting an empirical study involving 136 disaster professionals. The findings of this study extend the theory of TTF by incorporating the dual information processing modes and examine how disaster professionals evaluate these modes in disaster decision support processes.

Judging the Wrongness of Firms in Social Media Firestorms: The Heuristic and Systematic Information Processing Perspective

Social media firestorms pose a significant challenge for firms in the digital age. Tackling firestorms is difficult because the judgments and responses from social media users are influenced by not only the nature of the transgressions but also by the reactions and opinions of other social media users. Drawing on the heuristic-systematic information processing model, we propose a research model to explain the effects of social impact (the heuristic mode) and argument quality and moral intensity (the systematic mode) on perceptions of firm wrongness (the judgment outcome) as well as the effects of perceptions of firm wrongness on vindictive complaining and patronage reduction. We adopted a mixed methods approach in our investigation, including a survey, an experiment, and a focus group study. Our findings show that the heuristic and systematic modes of information processing exert both direct and interaction effects on individuals’ judgment. Specifically, the heuristic mode of information processing dominates overall and also biases the systematic mode. Our study advances the literature by offering an alternative explanation for the emergence of social media firestorms and identifying a novel context in which the heuristic mode dominates in dual information processing. It also sheds light on the formulation of response strategies to mitigate the adverse impacts resulting from social media firestorms. We conclude our paper with limitations and future research directions.

Untangling the Mystery of Intuitive-Analytic Interactions in Crisis Response Operations: A Dual-Process Perspective

Whilst it is often claimed that experienced crisis responders are likely to adopt the intuitive and analytical thinking styles when solving complex problems in time-pressured crisis situations, scholarly efforts to explicate the nature of interactions between the intuitive and analytical modes remain sparse. To bridge this gap, we review four duality-based cognitive models and draw evidence from the Hudson River case study to better understand the patterns of the interplay between the intuitive and analytical information processing modes in time-pressured crisis situations. We found support for the dual-process theory, and note that although intuition is frequently deployed as the default cognitive mode in crisis situations, experienced crisis responders can exploit some features of the analytical mode to validate their intuitive tendencies when required. Based on evidence from the Hudson River case study, a range of intuitive-analytic tension points that largely explain the nature of interactions within the duality framework are identified. The paper concludes by discussing the implications of the dual-process information modes for crisis decision-making.

Extracellular molecular signals shaping dendrite architecture during brain development.

Proper growth and branching of dendrites are crucial for adequate central nervous system (CNS) functioning. The neuronal dendritic geometry determines the mode and quality of information processing. Any defects in dendrite development will disrupt neuronal circuit formation, affecting brain function. Besides cell-intrinsic programmes, extrinsic factors regulate various aspects of dendritic development. Among these extrinsic factors are extracellular molecular signals which can shape the dendrite architecture during early development. This review will focus on extrinsic factors regulating dendritic growth during early neuronal development, including neurotransmitters, neurotrophins, extracellular matrix proteins, contact-mediated ligands, and secreted and diffusible cues. How these extracellular molecular signals contribute to dendritic growth has been investigated in developing nervous systems using different species, different areas within the CNS, and different neuronal types. The response of the dendritic tree to these extracellular molecular signals can result in growth-promoting or growth-limiting effects, and it depends on the receptor subtype, receptor quantity, receptor efficiency, the animal model used, the developmental time windows, and finally, the targeted signal cascade. This article reviews our current understanding of the role of various extracellular signals in the establishment of the architecture of the dendrites.

Modular brain network in volitional eyes closing: enhanced integration with a marked impact on hubs.

Volitional eyes closing would shift brain's information processing modes from the "exteroceptive" to "interoceptive" state. This transition induced by the eyes closing is underpinned by a large-scale reconfiguration of brain network, which is still not fully comprehended. Here, we investigated the eyes-closing-relevant network reconfiguration by examining the functional integration among intrinsic modules. Our investigation utilized a publicly available dataset with 48 subjects being scanned in both eyes closed and eyes open conditions. It was found that the modular integration was significantly enhanced during the eyes closing, including lower modularity index, higher participation coefficient, less provincial hubs, and more connector hubs. Moreover, the eyes-closing-enhanced integration was particularly noticeable in the hubs of network, mainly located in the default-mode network. Finally, the hub-dominant modular enhancement was positively correlated to the eyes-closing-reduced entropy of BOLD signal, suggesting a close connection to the diminished consciousness of individuals. Collectively, our findings strongly suggested that the enhanced modular integration with substantially reorganized hubs characterized the large-scale cortical underpinning of the volitional eyes closing.

On the ‘cognitive map debate’ in insect navigation

In a historical account recently published in this journal Dhein argues that the current debate whether insects like bees and ants use cognitive maps (centralized map hypothesis) or other means of navigation (decentralized network hypothesis) largely reflects the classical debate between American experimental psychologists à la Tolman and German ethologists à la Lorenz, respectively. In this dichotomy we, i.e., the proponents of the network hypothesis, are inappropriately placed on the Lorenzian line. In particular, we argue that in contrast to Dhein's claim our concepts are not based on merely instinctive or peripheral modes of information processing. In general, on the one side our approaches have largely been motivated by the early biocybernetics way of thinking. On the other side they are deeply rooted in studies on the insect's behavioral ecology, i.e., in the ecological setting within which the navigational strategies have evolved and within which the animal now operates. Following such a bottom-up approach we are not “anti-cognitive map researchers” but argue that the results we have obtained in ants, and also the results of some decisive experiments in bees, can be explained and simulated without the need of invoking metric maps.

Research on the Availability Heuristic and its Application

The availability heuristic refers to individuals making decisions based on the availability of relevant events as a shortcut. The paper focuses on the availability heuristic and its own unique information processing mode through literature reading and analysis. According to the discussion of the application, it can be concluded that the availability heuristic affects individual risk cognition and decision-making behavior. Future research should explore the root causes, explore the relationship between the availability heuristic and other phenomena, and expand the research field of its application.

The coupling between the spatial and temporal scales of neural processes revealed by a joint time-vertex connectome spectral analysis

Brain oscillations are produced by the coordinated activity of large groups of neurons and different rhythms are thought to reflect different modes of information processing. These modes, in turn, are known to occur at different spatial scales. Nevertheless, how these rhythms support different spatial modes of information processing at the brain scale is not yet fully understood. Here we use "Joint Time-Vertex Spectral Analysis" to characterize the joint spectral content of brain activity both in time (temporal frequencies) and in space over the connectivity graph (spatial connectome harmonics). This method allows us to characterize the relationship between spatially localized or distributed neural processes on one side and their respective temporal frequency bands in source-reconstructed M/EEG signals. We explore this approach on two different datasets, an auditory steady-state response (ASSR) and a visual grating task. Our results suggest that different information processing mechanisms are carried out at different frequency bands: while spatially distributed activity (which may also be interpreted as integration) specifically occurs at low temporal frequencies (alpha and theta) and low graph spatial frequencies, localized electrical activity (i.e., segregation) is observed at high temporal frequencies (high and low gamma) over restricted high spatial graph frequencies. Crucially, the estimated contribution of the distributed and localized neural activity predicts performance in a behavioral task, demonstrating the neurophysiological relevance of the joint time-vertex spectral representation.

The non-specific matrix thalamus facilitates the cortical information processing modes relevant for conscious awareness

The neurobiological mechanisms of arousal and anesthesia remain poorly understood. Recent evidence highlights the key role of interactions between the cerebral cortex and the diffusely projecting matrix thalamic nuclei. Here, we interrogate these processes in a whole-brain corticothalamic neural mass model endowed with targeted and diffusely projecting thalamocortical nuclei inferred from empirical data. This model captures key features seen in propofol anesthesia, including diminished network integration, lowered state diversity, impaired susceptibility to perturbation, and decreased corticocortical coherence. Collectively, these signatures reflect a suppression of information transfer across the cerebral cortex. We recover these signatures of conscious arousal by selectively stimulating the matrix thalamus, recapitulating empirical results in macaque, as well as wake-like information processing states that reflect the thalamic modulation of large-scale cortical attractor dynamics. Our results highlight the role of matrix thalamocortical projections in shaping many features of complex cortical dynamics to facilitate the unique communication states supporting conscious awareness.

Measuring the Persuasive Influence of Talk Show on Social Media Users: Applying Heuristic-Systematic Model with SEM

In today's digital age, talk shows have a substantial presence on multiscreen platforms. However, in studying their influence on the viewers, studies rarely investigated how they affect individuals' behavioral determinants, especially in addressing social issues. This present study aimed to fill this gap by exploring the persuasive influence of a talk show about social media usage on the viewers' attitude towards responsible use of social media based on the heuristic systematic information processing model. For this purpose, a video-embedded online questionnaire was used to collect relevant data from the heavy users’ segment of social media in Bangladesh (i.e., the university student social media users). SmartPLS 4.0 was used for partial least square structural equation modeling based on the data gathered from 226 voluntary respondents. The results show that exposure to the talk show does not directly associate with attitudes but with heuristic and systematic information processing modes that, in turn, influence attitude formation. In contrast, the systematic information processing mode predominates the formation of attitudes more than the heuristic mode. The findings have implications to add insights into creating awareness and developing prevention and educational interventions toward promoting responsible use of social media.

Endocranial volumes and human evolution.

Enlarging brains have been held up as the classic (if not the only) example of a consistent long-term trend in human evolution. And hominin endocranial volumes certainly expanded four-fold over the subfamily's seven-million-year history, while on a very coarse scale later hominids showed a strong tendency to have larger brains than earlier ones. However, closer scrutiny of this apparent trend reveals that it was extremely episodic and irregular, a fact that argues against the notion that it was driven by social interactions internal to the hominin clade. In addition, an overall tendency to brain volume increase was expressed independently and concurrently within at least three separate lineages of the genus Homo - suggesting that, whatever the exact influences were that promoted this global trend, they need to be sought among stimuli that acted comprehensively over the entire vast range of periods, geographies and environments that members of our subfamily occupied. Significantly, though, the dramatic recent shrinkage of the brain within the species Homo sapiens implies that the emergence of modern human cognition (via the adoption of the symbolic information processing mode, likely driven by the spontaneous invention of language in an exaptively enabled brain) was not the culmination of the overall hominin trend towards brain enlargement, but rather a departure from it.

The effects of CSR perceptions and agreements: applying the heuristic-systematic information processing model in CSR campaigns

ABSTRACT Although some scholars explored the heuristic-systematic information processing model in communication studies, little is known about how consumers’ CSR perceptions influence CSR information processing and how the different information process strategies can affect consumers’ purchase intentions. To address this research gap, this paper conducted an online survey to understand how consumers’ agreements on CSR can determine their information-processing modes and subsequently affect their purchase intentions. The results suggested that higher levels of consumer agreement were associated with both systematic and heuristic information processing modes. Additionally, this study found that the positive effect of consumers’ CSR agreements on purchase intention was mediated by the heuristic process, while an indirect effect involving the systematic process was not observed. Also, the moderated mediation model suggested that the indirect effects of consumers’ CSR agreements on purchase intentions through the heuristic process depended on intrinsic CSR attribution. The theoretical implications and practical contributions to CSR communication are discussed in detail.

When interruptions can boost sales: An on‐line versus memory‐based perspective

AbstractConsumer research about interruptions either assumes interruption homogeneity or single‐product evaluations. To remedy these problematic assumptions, this research explores the interplay between different interruption features (i.e., timing, frequency, and duration) and information processing modes (i.e., on‐line versus memory‐based) through the lens of impression formation theory. Two experiments show overall evaluations and purchase intentions for single products are highly sensitive to interruption features. For bundled products, this sensitivity disappears, and overall evaluations and purchase intentions remain stable regardless of the interruption's features. These results explain why unexpected marketing outcomes associated with frequent later and short interruptions or one early interruption during a decision process always induce better single‐product evaluations. These results also suggest several salesperson‐customer interaction strategies for practitioners.

Investigating innovation diffusion, social influence, and personal inner forces to understand people's participation in online e-waste recycling

By integrating the elaboration likelihood model (ELM), innovation diffusion theory (IDT) and social cognition theory (SCT), this study constructs a research model through which to explore the key factors and their influence mechanisms to understand people's participation in online e-waste recycling. Based on the ELM, we believe that people's behavioral intention to participate in online e-waste recycling is affected by the information processing of central and peripheral routes. Based on IDT, we take the perceived innovation characteristics as the key elements of the central route and consider social influence as the key element of the peripheral route. At the same time, we consider personal inner force factors, based on SCT, as the functional condition of the information processing mode to explore the moderating effects of privacy concern, pricing fairness concern, and environmental concern on the information processing of the central and peripheral routes. By taking discarded mobile phones as an example, we collect 475 valid samples to test our research model using the structural equation modelling (SEM) approach. The results confirm that perceived innovation characteristics and social influence are two factors that motivate people to participate in online e-waste recycling and that the three kinds of inner forces have different moderating effects on perceived innovation characteristics and social influence. Based on the above findings, this study puts forward some policy proposals.

Consumers' Acceptance, Emotions, and Responsiveness to Informational Cues for Air-Fried Catfish (Ictalurus punctatus) Skin Chips.

Catfish (Ictalurus punctatus) skins, as filleting byproduct, were developed into a crispy snack food via air-frying. Consumers rated catfish skin chips (CSC) across sensory modalities (9-point hedonic scales, a just-about-right scale, and "yes/no" for purchase intent, PI) for Plain-, Lemon & Pepper-, and Barbecue-flavored samples during two consumer studies (N = 115 each). Paprika- flavored CSC were excluded from Study 2 due to inferior acceptance and emotional ratings. CSC-elicited emotions were evaluated using a 25-term lexicon with CATA (Check-All-That-Apply) scaling (Study 1) and refined with an abbreviated lexicon containing food-evoked sensation-seeking emotions (5-point intensity scale). The two consumer studies differed in delivery format of product benefit information (a health/protein message and a food waste/sustainability message). Presenting two separate cues (Study 1) significantly increased overall liking (by 0.5 units) and PI (by 15%) for CSC compared to a single integrated message (Study 2), perhaps due to consumers' mode of information processing. Magnitude of increases was less for Barbeque CSC despite performing best overall (overall liking reaching 6.62 and PI reaching 61.7%). CSC generated mostly positive emotions, and informational cues increased sensation-seeking feelings, which can motivate trial of new foods. Accordingly, acceptance of CSC improved for 25 repeat-exposure consumers who participated in both Studies 1 and 2. In combination, sensory, cognitive, and emotional data showed favorable responses for flavored CSC as an appropriate application of this seafood byproduct.
