    Change blindness: eradication of gestalt strategies

    Get PDF
    Arrays of eight, texture-defined rectangles were used as stimuli in a one-shot change blindness (CB) task where there was a 50% chance that one rectangle would change orientation between two successive presentations separated by an interval. CB was eliminated by cueing the target rectangle in the first stimulus, reduced by cueing in the interval and unaffected by cueing in the second presentation. This supports the idea that a representation was formed that persisted through the interval before being 'overwritten' by the second presentation (Landman et al, 2003 Vision Research 43149–164]. Another possibility is that participants used some kind of grouping or Gestalt strategy. To test this we changed the spatial position of the rectangles in the second presentation by shifting them along imaginary spokes (by ±1 degree) emanating from the central fixation point. There was no significant difference seen in performance between this and the standard task [F(1,4)=2.565, p=0.185]. This may suggest two things: (i) Gestalt grouping is not used as a strategy in these tasks, and (ii) it gives further weight to the argument that objects may be stored and retrieved from a pre-attentional store during this task

    Money Illusion and Rational Expectations: New Evidence from Well Known Survey Data

    Get PDF
    This paper provides further evidence in favor of less than fully rational expectations by making use two instruments, one quite well known, and the other more novel, namely survey data on inflation expectations and Smooth Transition Error Correction Models (STECMs). We use the so called ‘probabilistic approach’ to derive a quantitative measure of expected inflation from qualitative survey data for France, Italy and the UK. The United States are also included by means of the Michigan Survey of Consumers’ expectations series. First, we perform the standard tests to assess the ‘degree of rationality’ of consumers’ inflation forecasts. Afterwards, we specify a STECM of the forecast error, and we quantify the strategic stickiness in the long-run adjustment process of expectations stemming from money illusion. Our evidence is that consumers’ expectations do not generally conform to the prescriptions of the rational expectations hypothesis. In particular, we find that the adjustment process towards the long-run equilibrium is highly nonlinear and it is asymmetric with respect to the size of the past forecast errors. We interpret these findings as supporting the money illusion hypothesis.Nonlinear error correction, inflation expectations, sticky expectations

    Is Virtual Marriage Acceptable? A Psychological Study Investigating The Role of Ambiguity Tolerance and Intimacy Illusion in Online Dating among Adolescents and Early Adults

    Get PDF
    Marriage is one of the most important topics in the education field since life in this world is structured by interaction among families and between families and other social institutions. Dissatisfaction and unsustainability of marriage have led the urgency of premarital education in various countries. The problem is that the spread of virtual reality has made marriage itself to become more complex and experience reinterpretation and reconfiguration, moreover with the emergence of new kind of marriage in the digital era, i.e. virtual marriage. Everybody who has observed, known, or even tried, certainly asks the question, “Could (or: should) I accept virtual marriage?” . This study was aimed to investigate the role of tolerance of ambiguity and illusion of intimacy in online dating in predicting the acceptance of virtual marriage. There were 420 adolescents and young adults (212 males, 208 females; Mage=21.10 years old, SDage=1.459 years; 338 students, 82 employees or entrepreneurs) in the Greater Jakarta, Indonesia, participated in this study. It was found that the acceptance was not predicted by the ambiguity tolerance, but by the illusion of intimacy in online dating. The psychometric issues, substantive discussion, and recommendation are presented at the end of this article. The trend of virtual marriage should not be allowed to roll away, by autopilot, without loaded by strategies in designing an online game as one of the pivotal educational technologies that needs to shape appropriate character and attitude for it
