As the need for collaboration across multiple organizations to deal with complex social issues such as poverty, crime, and public health grows, Public–Private Partnership (PPP) is of increasing importance. However, little is known about when and why private firms engage in such partnerships. Drawing on upper-echelon theory and the information-processing perspective, we highlight the importance of institutional knowledge and information embedded in CEO cross-sector work experience. We argue that such tacit knowledge and information enables CEOs to better identify the potential risks associated with PPPs. Consequently, CEOs with cross-sector work experience tend to be more cautious in participating in such partnerships, especially in developing economies like China, where private actors face greater information incompleteness concerning post-collaboration hazards due to the government's selective disclosure. Moreover, we develop a multi-moderator framework in which regional marketization and political connection alter the main effect by serving as supplementary information channels for private actors. A panel dataset of Chinese private listed firms from 2013 to 2021 provides strong support for our hypotheses. This study contributes to our understanding of the micro-foundation of PPP formation and draws attention to CEOs’ prior career experiences in different organizational forms.
This chapter examines how attitudes are formed. Attitude formation is explained as a function of prior beliefs and information. This process is viewed through two complementary lenses: the static process and the dynamic process. The static model thinks of attitudes as a combination of ratings and rankings. We term this the multi-attribute model – a commonly used approach in psychology and economics. The dynamic model concentrates on how humans process information, where things like words, symbols, and memory networks take on practical significance. Ultimately, both models have many applications for the practitioner.
Governors are motivated to change public policy in response to issues and have powers that influence the shape and direction of budgets; however, interest groups are ultimately providing opportunities for action. We conclude with some broad recommendations for institutional and political tinkering in the American states. Specifically, we argue that policymakers can embrace the inevitability of interest group involvement in policymaking and be more thoughtful about the way they structure policies. This process enables diversity – by which we mean more groups with difference and alternative policy concerns – in representation. In addition, we argue that decentralization of gubernatorial power over the budget to alternative institutions could facilitate budgets that are more responsive to problems.
Finnish nonfinite clauses constitute a complex grammatical class with a seemingly chaotic mix of verbal and nominal properties. Thirteen nonfinite constructions, their selection, control, thematic role assignment, nonfinite agreement, embedded subjects, and syntactic status were targeted for analysis. An analysis is proposed which derives their syntactic and semantic properties by relying on a computational model of human information processing. The model analyzes Finnish nonfinite constructions as truncated clauses with one functional layer above the verb phrase. Research methods from naturalistic cognitive science and computational linguistics are considered as potentially useful tools for linguistics.

Converging lines of pre-clinical, epidemiological, and experimental evidence support an association between cannabis, cannabinoid agonists, and psychosis (see Chapters 14 and 15). The earliest anecdotal reports on observations between the use of cannabis and subsequent psychosis have been validated by a rich literature of longitudinal studies and more recently experimental studies in humans using a wide array of subjective, cognitive, and electrophysiological outcomes relevant to psychosis. This chapter provides an overview of the subjective psychotic phenomena associated with cannabis and cannabinoids and expands on more objective cognitive and psychophysiological cannabis-related effects pertinent to psychosis.
Programmable active matter (PAM) combines information processing and energy transduction. The physical embodiment of information could be the direction of magnetic spins, a sequence of molecules, the concentrations of ions, or the shape of materials. Energy transduction involves the transformation of chemical, magnetic, or electrical energies into mechanical energy. A major class of PAM consists of material systems with many interacting units. These units could be molecules, colloids, microorganisms, droplets, or robots. Because the interaction among units determines the properties and functions of PAMs, the programmability of PAMs is largely due to the programmable interactions. Here, we review PAMs across scales, from supramolecular systems to macroscopic robotic swarms. We focus on the interactions at different scales and describe how these (often local) interactions give rise to global properties and functions. The research on PAMs will contribute to the pursuit of generalised crystallography and the study of complexity and emergence. Finally, we ponder on the opportunities and challenges in using PAM to build a soft-matter brain.
Affective states play a key function in creative performance, such that both positive and negative feelings can foster, or inhibit, creativity due to their information processing and motivational correlates. In this chapter, we survey and integrate theory and empirical research in this field, identifying core and robust findings focused on the association of affect with creativity, and unanswered questions requiring deeper investigation. Based on this work, we finally propose several valuable directions for future research.
Voters prefer political candidates who are currently in office (incumbents) over new candidates (challengers). Using the premise of query theory (Johnson, Häubl & Keinan, 2007), we clarify the underlying cognitive mechanisms by asking whether memory retrieval sequences affect political decision making. Consistent with predictions, Experiment 1 (N= 256) replicated the incumbency advantage and showed that participants tended to first query information about the incumbent. Experiment 2 (N= 427) showed that experimentally manipulating participants’ query order altered the strength of the incumbency advantage. Experiment 3 (N= 713) replicated Experiment 1 and, in additional experimental conditions, showed that the effects of incumbency can be overridden by more valid cues, like the candidates’ ideology. Participants queried information about ideologically similar candidates earlier and also preferred these ideologically similar candidates. This is initial evidence for a cognitive, memory-retrieval process underling the incumbency advantage and political decision making.
In decision making, people may rely on their own information as well as oninformation from external sources, such as family members, peers, or experts.The current study investigated how these types of information are used bycomparing four decision strategies: 1) an internal strategy that relies solelyon own information; 2) an external strategy that relies solely on theinformation from an external source; 3) a sequential strategy that relies oninformation from an external source only after own information is deemedinadequate; 4) an integrative strategy that relies on an integration of bothtypes of information. Of specific interest were individual and developmentaldifferences in strategy use. Strategy use was examined via Bayesian hierarchicalmixture model analysis. A visual decision task was administered to children andyoung adolescents (N=305, ages 9–14). Individual differences but noage-related changes were observed in either decision accuracy or strategy use.The internal strategy was dominant across ages, followed by the integrative andsequential strategy, respectively, while the external strategy was extremelyrare. This suggests a reluctance to rely entirely on information provided byexternal sources. We conclude that there are individual differences but notdevelopmental changes in strategy use pertaining to perceptual decision-makingin 9- through 14-year-olds. Generalizability of these findings is discussed withregard to different forms of social influence and varying perceptions of theexternal source. This study provides stepping stones in better understanding andmodeling decision making processes in the presence of both internal and externalinformation.
Pie charts are often used to communicate risk, such as the risk of driving. In the foreground-background salience effect (FBSE), foreground (probability of bad event) has greater salience than background (no bad event) in such a chart. Experiment 1 confirmed that the displays format of pie charts showed a typical FBSE. Experiment 2 showed that the FBSE resulted from a difference in cognitive efforts in processing the messages and that a foreground-emphasizing display was easier to process. Experiment 3 manipulated subjects’ information processing mindset and explored the interaction between displays format and information processing mindset. In the default mindset, careless subjects displayed a typical FBSE, while those who were instructed to be careful reported similar risk-avoidant behavior preference reading both charts. Suggestions for improving risk communication are discussed.
The influence of numeracy on information processing of two risk communication formats (percentage and pictograph) was examined using an eye tracker. A sample from the general population (N = 159) was used. In intuitive and deliberative decision conditions, the participants were presented with a hypothetical scenario presenting a test result. The participants indicated their feelings and their perceived risk, evoked by a 17% risk level. In the intuitive decision condition, a significant correlation (r = .30) between numeracy and the order of information processing was found: the higher the numeracy, the earlier the processing of the percentage, and the lower the numeracy, the earlier the processing of the pictograph. This intuitive, initial focus on a format prevailed over the first half of the intuitive decision-making process. In the deliberative decision condition, the correlation between numeracy and order of information processing was not significant. In both decision conditions, high and low numerates processed pictograph and percentage formats with similar depths and derived similar meanings from them in terms of feelings and perceived risk. In both conditions numeracy had no effects on the degree of attention on the percentage or the pictograph (number of fixations on formats and transitions between them). The results suggest that pictographs attract low numerates’ attention, and percentages attract high numerates’ attention in the first, intuitive, phase of numeric information processing. Pictographs thus ensure low numerates’ further elaboration on numeric risk information, which is an important precondition of risk understanding and decision making.
The fourth edition of this popular text has been significantly rewritten to make it more accessible to students and easier for instructors to use. It remains distinctive in presenting a unified narrative of cognitive science as a field of inquiry in its own right. Thematically organized, Cognitive Science underscores the problems and solutions of cognitive science rather than more narrowly examining individually the subjects that contribute to it - psychology, neuroscience, linguistics, and so on. The generous use of examples, illustrations, and applications demonstrates how theory and experiment can be applied to unlock the mysteries of the human mind. Drawing upon cutting-edge research, the text has been updated and enhanced with a new chapter on emotions and the emerging field of affective science. An extensive online set of resources is available to aid both instructors and students.
This chapter considers how connectionist neural networks offer a contrast to the symbolic view of representation discussed in previous chapters. We start by reviewing the structure of neural networks inspired by neurobiology, comparing a single unit in a neural network to a biological neuron. The second section looks at the simplest form of neural network -- a single-layer neural network using the perceptron convergence rule for learning. The third section introduces multilayer neural networks and the development of the backpropagation algorithm. Next, we look at how the multilayer neural network can be trained, and its biological plausibility. The last section summarizes three critical features of information processing in neural networks, as opposed to physical symbol systems: distributed representations, the lack of a clear distinction between storing and processing information, and the ability to learn.
This chapter looks back to the pioneering studies that prefigured the emergence of cognitive science, subsequently converging into this new interdisciplinary field in the late 1970s. The first section addresses a key turning point in psychology. Whereas behaviorism holds that all explicit behaviors are the product of conditioning, it became clear that animals can manipulate representations of the environment to solve complex problems without reinforcement. The second section introduces the Turing machine developed by Turing in the 1930s, illustrating that purely mechanical procedures can process information algorithmically. The idea of a computable machine contributed to the birth of computer science and provided a model for thinking about how the mind processes information. Chomsky's transformational grammar offers a classic example of a computable model of how complex sentences convey information as a function of basic syntax rules. Finally, Miller and Broadbent's findings on attention support applying the information-processing model in psychology. These pioneering researchers were the first to lay out some of what were to be the basic concepts of cognitive science.
Rational choice theory explains and evaluates how individuals choose among alternative instruments to achieve their goals and objectives. Although much research on political decision-making highlights psychological biases that appear to interfere with rationality, the contrast between rational choice and the psychology of information processing is often narrowed by individual and contextual conditions that reduce cognitive biases and promote rational decision-making. This argument is developed by analysing research on heuristics (i.e., shortcuts and cues), motivated reasoning, and framing that pose challenges to rational choice. Three themes emerge from this review. First, there is systematic variation across individuals in the extent to which heuristics, biased reasoning, and framing produce unreasonable and suboptimal decisions. Second, there are definable informational and social contexts that provide incentives for people to engage in deliberate and accurate processing of information. Third, normative evaluations of empirical results have been hampered by inconsistent criteria for what constitutes good decision-making.
Today’s information environment is drastically different from the heyday of print and broadcast, but these changes exceed the scope of researchers’ agendas. More is known now than when these technologies were in their infancy, yet efforts to understand the implications of changing communication technology for media effects have produced mixed findings, limiting progress towards cohesive and generalisable theoretical explanations. A literature review suggests one reason for this is that media effects scholarship has often neglected insights from political psychology and information processing, contributing to a lack of theoretical coherence across these bodies of work. Though research thoroughly examines directional motivations dictating media choice and exposure, it does not equally consider other cognitive biases driving choice, exposure, and processing, which can offset effects from the structural aspects of digital media. Given ample evidence that communication technology influences information processing, any viable, contemporary explanation of media effects must reconcile with these literatures.
Our time seems to be trapped in a paradox. On the one hand, the capacity to master information has tremendously increased, but on the other hand the capacity to use the knowledge humanity produces seems at stake. There is a gap between our capacity to know and our capacity to act. We attempt to better understand that situation by considering the evolution of knowledge processing along human history, in particular the relation between the development of information technologies and the complexity of societies, the balance between the known and the unknown, and the current emergence of autonomous machines allowing intelligent processes.
Technical summary
Information-processing capacities developed historically in conjunction with the complexity of human societies. Positive feedback loops contributed to the co-evolution of knowledge, social organization, environmental transformation, and information technologies. Very powerful loops now drive the rapid emergence of global digital platforms, disrupting legacy organizations and economic equilibria. The simultaneous emergence of the awareness of the sustainability conundrum and the digital revolution is striking. Both are extremely disruptive and contribute to a surge in complexity, but how do they relate to each other? Paradoxically, as the capacity to master information increases, the capacity to use the knowledge humanity produces seems to lag. The objective of this paper is to analyze the current divergence between knowledge and action, from the angle of the co-evolution of information processing and societal transformation. We show how the interplay between perception and action, between the known and the unknown, between information processing and ontological uncertainty, has evolved toward a sense of control, a hubris, which abolishes the unknown and hinders action. A possible outcome of this interplay might lead to a society controlled to stay in its safe operating space, involving a strong delegation of information processing to autonomous machines, as well as extensive forms of biopolitics.
Social media summary
The sustainability conundrum and the digital revolution are entangled phenomena leading to complexity and disruption.
Difficulties in the ability to adapt beliefs in the face of new information are associated with psychosis and its central symptom – paranoia. As cognitive processes and psychotic symptoms are both known to be sensitive to stress, the present study investigated the exact associations between stress, adapting of beliefs [reversal learning (RL), bias against disconfirmatory evidence (BADE), and jumping to conclusions (JTC)] and paranoia. We hypothesized that paranoia would increase under stress and that difficulties in adapting of beliefs would mediate or moderate the link between stress and paranoia. Furthermore, we hypothesized that the investigated effects would be strongest in the group of individuals diagnosed with a psychotic disorder.
Methods
We exposed 155 participants (38 diagnosed with a psychotic disorder, 40 individuals with attenuated psychotic symptoms, 39 clinical controls diagnosed with an obsessive-compulsive disorder, and 38 healthy controls) to a control condition and a stress condition, in which we assessed their levels of paranoia and their ability to adapt beliefs. We applied multilevel models to analyze the data.
Results
Paranoia was higher in the stress condition than in the control condition, b = 1.142, s.e. = 0.338, t(150) = 3.381, p < 0.001. RL, BADE, and JTC did not differ between conditions and did not mediate or moderate the association between stress and paranoia (all ps > 0.05).
Conclusions
The results support the assumption that stress triggers paranoia. However, the link between stress and paranoia does not seem to be affected by the ability to adapt beliefs.
Partisan and affective polarization should have observable consequences in Canada, such as bias in political information search and processing. This article presents the results of three studies that test for partisan and ideological bias using the Digital Democracy Project's study of the 2019 Canadian election. Study 1 uses a conjoint experiment where respondents choose from pairs of hypothetical news stories where the slant of the source and headline are both randomized. Study 2 tests for partisan-motivated responsiveness to elite cues with a policy vignette that manipulates the presence of party elite cues and a motivational prime. Study 3 requires respondents to solve a randomly assigned numeracy task that is either political or nonpolitical in nature. Results suggest that Canadians (1) select politically congenial information, though not sources of such information, (2) follow elite cues when partisan motivation is primed and (3) evaluate evidence in ways that are biased by their ideological beliefs.
Most empirical studies about chess have taken the happenstance of the cognitive or experimental paradigm within psychology. In this chapter, the past main research findings from this approach will be reviewed together with their contribution to psychological science. The chapter is structured into three main subsections, perception, memory, and thinking. Each of these sections describe more specific themes such as information processing models, eye movements, theories of memory in chess, and thinking methods such as pattern recognition and search. The main conclusions from this extensive body of research are summarized through the prism of the individual differences approach.
