Swarming Models for Facilitating Collaborative Decisions
2010
The paper highlights the computational power of swarming models (i.e., stigmergic mechanisms) to build collaborative support systems for complex cognitive tasks such as facilitation of group decision processes (GDP) in e-meetings. Unlike traditional approaches that minimize the cognitive complexity by incorporating the facilitation knowledge into the system, stigmergic coordination mechanisms minimize the complexity by providing the system with emergent functionalities that are shaped by the environment itself through the possibility to structure it in terms of high-level cognitive artefacts. This is illustrated by conducting a socio-simulation experiment for an envisioned collaborative sof…
Best not to bet on the horserace: A comment on Forrin and MacLeod (2017) and a relevant stimulus-response compatibility view of colour-word contingen…
2018
International audience; One powerfully robust method for the study of human contingency learning is the colour-word contingency learning paradigm. In this task, participants respond to the print colour of neutral words, each of which is presented most often in one colour. The contingencies between words and colours are learned, as indicated by faster and more accurate responses when words are presented in their expected colour relative to an unexpected colour. In a recent report, Forrin and MacLeod (2017b, Memory & Cognition) asked to what extent this performance (i.e., response time) measure of learning might depend on the relative speed of processing of the word and the colour. With keypr…
GENERALITY OF GRAPHIC VARIABLES ACROSS DRAWING TASKS
1968
Konttinen, R. & Olkinuora, E. Generality of graphic variables across drawing tasks. Scund. J. Psychol., 1968, 9, 161–168.—As a partial replication of the Takala & Rantanen (1964) study, the correlations between 6 graphic variables extracted from 6 drawing tasks differing in complexity were investigated. Four graphic trait factors were obtained I Size, II Pressure, III Discontinuous lines, and IV Angularity. Other graphic variables (nuancity and reinforcement) loaded factors II and III. The data lend support to the hypothesis that the same graphic traits should be interpreted in the same way irrespective of the complexity of the test. However, the complexity of the drawing task may make a di…
IsMilkmana superhero likeBatman? Constituent morphological priming in compound words
2009
In the present study, we examined morphological decomposition of Basque compound words in a series of masked priming lexical decision experiments. In Experiment 1, Basque compound words could be briefly preceded by other compounds that shared either the first or second constituent, or by unrelated noncompound words. Results showed a significant priming effect for words that shared a constituent, independently of its position. In Experiment 2, compound words were preceded by other compound words that shared one of their constituents, but in a different lexeme position (e.g., the first constituent of the compound that acted as a prime was the second constituent of the compound that acted as a…
Null Effect of Set Size in Lexical Decision
1995
The effect of set size indicates that recall of a word is greater when its cue is associated with fewer words. This study was designed to replicate this result with lexical decisions of 18 students. In spite of obtaining the set-size effect with cue recall, it was not observed with lexical decision.
Effect of Prime and Target Repetition on Lexical Decision Time
1992
On a prime-target lexical decision task we manipulated the relatedness between prime and target (semantically related or unrelated), the number of repetitions (from 1 to 5), the type of the repeated stimulus (only the prime, only the target, or both), and the stimulus onset asynchrony (within a range of automatic activation from 60 to 400 msec.) to find whether semantic and repetition priming are additive (or interact), and whether there is episodic priming in an automatic, nonconscious way. Analysis showed repetition and semantic priming were additive rather than interactive. No episodic automatic priming was found. Results are discussed in terms of the predictions made from the main theo…
Goal Setting and Monetary Incentives: When Large Stakes Are Not Enough
2012
The aim of this paper is to test the effectiveness of wage-irrelevant goal setting policies in a laboratory environment. In our design, managers can assign a goal to their workers by setting a certain level of performance on the work task. We establish our theoretical conjectures by developing a model in which assigned goals act as reference points to workers’ intrinsic motivation. Consistent with our model, we find that managers set goals which are challenging but attainable for an average-ability worker. Workers respond to these goals by increasing effort, performance and by decreasing on-the-job leisure activities with respect to the no-goal setting baseline. Finally, we study the intera…
Recent advances of HCI in decision-making tasks for optimized clinical workflows and precision medicine.
2020
The ever-increasing amount of biomedical data is enabling new large-scale studies, even though ad hoc computational solutions are required. The most recent Machine Learning (ML) and Artificial Intelligence (AI) techniques have been achieving outstanding performance and an important impact in clinical research, aiming at precision medicine, as well as improving healthcare workflows. However, the inherent heterogeneity and uncertainty in the healthcare information sources pose new compelling challenges for clinicians in their decision-making tasks. Only the proper combination of AI and human intelligence capabilities, by explicitly taking into account effective and safe interaction paradigms,…
Development of conditional reasoning and Wason's selection task
2004
Influent theories on human reasoning have suggested that Wason's selection task is so difficult because it involves heuristic and implicit processes. However, recent studies have demonstrated the implication of deductive activities. Poor performance on this task would thus result from some of its characteristics that impede the use of deductive processes. In the present experiment, we hypothesised that a modified abstract selection task that induces analytic and deductive processes should lead to better performance than the standard version of the task. Moreover, deductive activities are strongly affected by development (Markovits et Barrouillet, 2002). Thus, we predicted a strong developme…
Do Individual Effects Reflect Quantitative or Qualitative Differences in Cognition?
2021
Rouder and Haaf (2020) posed the important question if there are some individuals whose behavior is not in accordance with well-established experimental effects and whether these individual differences are quantitative or qualitative in nature. In our commentary, we discuss the distinction between quantitative and qualitative individual differences and between individual and average causal effects and come to the conclusion that this is not a new question, but in fact one that has already been discussed by Gordon W. Allport (1937) and Donald B. Rubin (1974, 1978). Moreover, we critically examine their proposed rule of thumb to collect about 100 trials per experimental condition to reliably …
