The Psychology of Fluent Use

2016

In a perfect world, it would always be possible to operate technology effortlessly and to reach the desired goal. However, in the real world many factors may make technologies difficult to use or even hinder people from using technical artefacts. Most of these factors pertain to usability (i.e., technology’s ability to fit users’ capabilities) and thus concern technological solutions from the point of view of human beings as users of technology. Therefore, designing technical artefacts that are easy to use requires understanding the psychological and mental preconditions for using technology.

Does order and timing in performance of imagined and actual movements affect the motor imagery process? The duration of walking and writing task.

2002

The purpose of the present study was to investigate the effects on the duration of imagined movements of changes in timing and order of performance of actual and imagined movement. Two groups of subjects had to actually execute and imagine a walking and a writing task. The first group first executed 10 trials of the actual movements (block A) and then imagined the same movements at different intervals: immediately after actual movements (block I-1) and after 25 min (I-2), 50 min (I-3) and 75 min (I-4) interval. The second group first imagined and then actually executed the tasks. The duration of actual and imagined movements, recorded by means of an electronic stopwatch operated by the subj…

The Third Way of Cognitive Science and the Middle Way of Buddhism

2013

Even though cognitive science may not be established as a mature science, being rather a loose affiliation of disciplines which make human cognition a scientific theme, it has already had significant impact in the field of epistemology. Since the late 1970s, research conducted on aspects of cognition ranging from perception to language has laid the groundwork for a fundamental epistemological shift in cognitive science, which bears directly on the Western philosophical dilemma of whether reality is objective (and independent of our cognition) or subjective (and so our mind’s projection). My aim here is to trace some major developments in the history of cognitive science leading to the emerg…

The Development of Visuo-spatial Memory: How to Remember Location

1992

Recent studies on developmental differences in spatial memory have reported equivocal results. Some found an age-dependent improvement of memory performance whereas others did not. The two studies reported here investigate age differences in memory for visual-spatial information. A picture reconstruction task with simultaneous presentation of scene-like visual-spatial arrangements was used. Subjects had to recognise objects and to reconstruct the initial spatial arrangement. The first study with 5to 10year-olds produced the typical age-dependent improvement in recognising visual material as well as in remembering the locations of specific objects. No effect for age was obtained in memory f…

Mental representation of arm motion dynamics in children and adolescents.

2013

International audience; Motor imagery, i.e., a mental state during which an individual internally represents an action without any overt motor output, is a potential tool to investigate action representation during development. Here, we took advantage of the inertial anisotropy phenomenon to investigate whether children can generate accurate motor predictions for movements with varying dynamics. Children (9 and 11 years), adolescents (14 years) and young adults (21 years) carried-out actual and mental arm movements in two different directions in the horizontal plane: rightwards (low inertia) and leftwards (high inertia). We recorded and compared actual and mental movement times. We found th…

How older and younger people see technology in Northern and Southern Europe : Closing the generation gap

2016

Background Mental representations of technology can be affected by many social and biological factors. The aim of this study was to test the effects of two of these factors, age and culture, on how people mentally represent and experience technologies by comparing the conceptions of old and young people in Spain and Finland. Both Spain and Finland are European countries, but they are historically, geographically, and culturally very different. Method The study is framed within the life-based design (LBD) paradigm, where culture and age interact to define particular forms of life in which technology might be used and perceived differently. We hypothesised that there are differences in the me…

Concept Maps for Comprehension and Navigation of Hypertexts

2013

Comprehension and learning with hypertexts are challenging due to the nonlinearity of such digital documents. Processing hypertexts may involve navigation and comprehension problems, leading learners to cognitive overhead. Concept maps have been added to hypertexts to reduce the cognitive requirements of navigation and comprehension. This chapter explores the literature to examine the effects of concept maps on navigation, comprehension, and learning from hypertexts. The literature review aims to elucidate how concept maps may contribute to processing hypertexts and under which conditions. In spite of the variability of concept maps used in hypertexts, some findings converge. Concept maps r…

Initial state azimuthal anisotropies in small collision systems

2015

Strong multiparticle azimuthal correlations have recently been observed in high energy proton-nucleus collisions. While final state collective effects can be responsible for many of the observations, the domain structure in the classical color field of a high energy nucleus also naturally leads to such correlations. We describe recent calculations of the momentum space 2-particle cumulant azimuthal anisotropy coefficients v_n{2}, n=2,3,4 from fundamental representation Wilson line distributions describing the high energy nucleus. We find significant differences between Wilson lines from the MV model and from JIMWLK evolution. We also discuss the relation of this calculation to earlier work …
