  • Parameter estimation approaches for multinomial processing tree models: A comparison for models of memory and judgment
    J. Math. Psychol. (IF 2.635) Pub Date : 2020-08-01
    Julia Groß; Thorsten Pachur

    Multinomial processing tree (MPT) models are commonly used in cognitive psychology to disentangle and measure the psychological processes underlying behavior. Various estimation approaches have been developed to estimate the parameters of MPT models for a group of participants. These approaches are implemented in various programs (e.g., MPTinR, TreeBUGS) and differ with regard to how data are pooled

    This paper introduces the bi-separability of items in knowledge structures as a bidirectional separability of items. Let (Q,K) be the knowledge structure delineated by the skill multimap (Q,S,μ). This paper gives some necessary and sufficient conditions, expressed in terms of competencies of μ, ensuring that (Q,K) is discriminative (resp. bi-discriminative), which generalizes the discussion of the

    Audiovisual integration can facilitate speech comprehension by integrating information from lip-reading with auditory speech perception. When incongruent acoustic speech is dubbed onto a video of a talking face, this integration can lead to the McGurk illusion of hearing a different phoneme than that spoken by the voice. Several computational models of the information integration process underlying

    The cardinal secretary search problem confronts the decision maker with more or less candidates who have identically and independently distributed values and appear successively in a random order without recall of earlier candidates. Its benchmark solution implies monotonically decreasing sequences of optimal value aspirations (acceptance thresholds) for any number of remaining candidates. We compare

    In a variety of real-world forecasting contexts, researchers have demonstrated that the unweighted average forecast is reasonably accurate and difficult to improve upon with more complex, model-based aggregation methods. We investigate this phenomenon by systematically examining the relationship between individual forecaster characteristics (e.g., bias, consistency) and aspects of the criterion being

    Christopher W. Doble; Yung-Fong Hsu

    Writing ξs(x) for the stimulus intensity judged greater (louder, heavier, brighter) than stimulus intensity x with criterion s, Iverson (2006b) proposed a law of similarity ξs(λx)=γ(λ,s)ξη(λ,s)(x) to model the dependence of ξs(x) on x. This model, which has η(λ,s) and γ(λ,s) as parameters, is quite general and may be applied in a number of situations in psychophysics. Iverson (2006b) analyzed this

    Forecasts are generated by both human experts and statistical models, and their forecast accuracy can be understood using error decompositions.

    The ACT-R cognitive architecture is a computational framework for developing, simulating and testing comprehensive theories of cognition.

    Invariant item ordering refers to the statement that if one item is harder than another for one person, then it is harder for all people. Whether item ordering holds is a psychological statement because it describes how people may qualitatively vary. Yet, modern item response theory (IRT) makes an a priori commitment to item ordering. The Rasch model, for example, posits that items must order. Conversely

    The detection response task (DRT) is a measure of workload that can assess the cognitive demands of real-world multitasking. It can be configured to present simple stimuli of several modalities, including auditory and visual signals.

    The marginal likelihood plays an important role in many areas of Bayesian statistics such as parameter estimation, model comparison, and model averaging. In most applications, however, the marginal likelihood is not analytically tractable and must be approximated using numerical methods. Here we provide a tutorial on bridge sampling (Bennett, 1976; Meng & Wong, 1996), a reliable and relatively straightforward

  • Model-based functional neuroimaging using dynamic neural fields: An integrative cognitive neuroscience approach.
    J. Math. Psychol. (IF 2.635) Pub Date : 2017-11-10
    Sobanawartiny Wijeakumar,Joseph P Ambrose,John P Spencer,Rodica Curtu

    A fundamental challenge in cognitive neuroscience is to develop theoretical frameworks that effectively span the gap between brain and behavior, between neuroscience and psychology. Here, we attempt to bridge this divide by formalizing an integrative cognitive neuroscience approach using dynamic field theory (DFT). We begin by providing an overview of how DFT seeks to understand the neural population

  • Recasting a biologically motivated computational model within a Fechnerian and random utility framework.
    J. Math. Psychol. (IF 2.635) Pub Date : 2017-08-23
    Clintin P Davis-Stober,Nicholas Brown,Sanghyuk Park,Michel Regenwetter

    The selective integration model of Tsetsos et al. (2016a) is a biologically motivated computational framework that aims to model intransitive preference and choice. Tsetsos et al. (2016a) concluded that a noisy system can lead to violations of transitivity in otherwise rational agents optimizing a task. We show how their model can be interpreted from a Fechnerian perspective and within a random utility

    Research in psychology and neuroscience has successfully modeled decision making as a process of noisy evidence accumulation to a decision bound. While there are several variants and implementations of this idea, the majority of these models make use of a noisy accumulation between two absorbing boundaries. A common assumption of these models is that decision parameters, e.g., the rate of accumulation

  • Comparing fixed and collapsing boundary versions of the diffusion model.
    J. Math. Psychol. (IF 2.635) Pub Date : 2017-06-06
    Chelsea Voskuilen,Roger Ratcliff,Philip L Smith

    Optimality studies and studies of decision-making in monkeys have been used to support a model in which the decision boundaries used to evaluate evidence collapse over time. This article investigates whether a diffusion model with collapsing boundaries provides a better account of human data than a model with fixed boundaries. We compared the models using data from four new numerosity discrimination

  • How attention influences perceptual decision making: Single-trial EEG correlates of drift-diffusion model parameters.
    J. Math. Psychol. (IF 2.635) Pub Date : 2017-04-25
    Michael D Nunez,Joachim Vandekerckhove,Ramesh Srinivasan

    Perceptual decision making can be accounted for by drift-diffusion models, a class of decision-making models that assume a stochastic accumulation of evidence on each trial. Fitting response time and accuracy to a drift-diffusion model produces evidence accumulation rate and non-decision time parameter estimates that reflect cognitive processes. Our goal is to elucidate the effect of attention on visual

  • RELATING ACCUMULATOR MODEL PARAMETERS AND NEURAL DYNAMICS.
    J. Math. Psychol. (IF 2.635) Pub Date : 2017-04-11
    Braden A Purcell,Thomas J Palmeri

    Accumulator models explain decision-making as an accumulation of evidence to a response threshold. Specific model parameters are associated with specific model mechanisms, such as the time when accumulation begins, the average rate of evidence accumulation, and the threshold. These mechanisms determine both the within-trial dynamics of evidence accumulation and the predicted behavior. Cognitive modelers

  • A tutorial on the free-energy framework for modelling perception and learning.
    J. Math. Psychol. (IF 2.635) Pub Date : 2017-03-17
    Rafal Bogacz

    This paper provides an easy to follow tutorial on the free-energy framework for modelling perception developed by Friston, which extends the predictive coding model of Rao and Ballard. These models assume that the sensory cortex infers the most likely values of attributes or features of sensory stimuli from the noisy inputs encoding the stimuli. Remarkably, these models describe how this inference

  • Identification of probabilities.
    J. Math. Psychol. (IF 2.635) Pub Date : 2017-03-17
    Paul M B Vitányi,Nick Chater

    Within psychology, neuroscience and artificial intelligence, there has been increasing interest in the proposal that the brain builds probabilistic models of sensory and linguistic input: that is, to infer a probabilistic model from a sample. The practical problems of such inference are substantial: the brain has limited data and restricted computational resources. But there is a more fundamental question:

    Studies of the primate visual system have begun to test a wide range of complex computational object-vision models. Realistic models have many parameters, which in practice cannot be fitted using the limited amounts of brain-activity data typically available. Task performance optimization (e.g. using backpropagation to train neural networks) provides major constraints for fitting parameters and discovering

  • Integrating Theoretical Models with Functional Neuroimaging.
    J. Math. Psychol. (IF 2.635) Pub Date : 2017-03-14
    Michael S Pratte,Frank Tong

    The development of mathematical models to characterize perceptual and cognitive processes dates back almost to the inception of the field of psychology. Since the 1990s, human functional neuroimaging has provided for rapid empirical and theoretical advances across a variety of domains in cognitive neuroscience. In more recent work, formal modeling and neuroimaging approaches are being successfully

    Our understanding of cognition has been advanced by two traditionally nonoverlapping and non-interacting groups. Mathematical psychologists rely on behavioral data to evaluate formal models of cognition, whereas cognitive neuroscientists rely on statistical models to understand patterns of neural activity, often without any attempt to make a connection to the mechanism supporting the computation.
