Expectancy‐effects without expectancies: Illusory correlations based on cue‐overlap

Expectancy‐based illusory correlations have been observed in numerous experiments. Simulations using the connectionist computer model BIAS (Fiedler, 1996 ) show that such illusory correlations may not always reflect expectancy biases but influences of similarity via cue‐overlap. Cue‐overlap means that some of the probabilistic cues that indicate the presence of one variable are also indicative of another variable. In an experiment, participants learned two novel concepts pertaining to a fictitious painter and a fictitious artistic style in separate runs. Both concepts were defined by multiple probabilistic cues observable in paintings. For half the participants, the cue systems underlying the perception of the two concepts overlapped, whereas for the other half they did not. In addition, we manipulated whether or not participants expected a positive contingency between artist and artistic style. In the second part of the experiment, a series of paintings was presented that constituted an objective zero correlation between artist and artistic style. Participants' subsequent contingency judgments were assessed by direct and indirect measures. Data analyses revealed main effects for expectancy induction and cue‐overlap but no interaction on the direct measure and nearly identical results on the indirect measure. Thus, cue‐overlap and expectancy induction independently triggered the development of illusory correlations. Copyright © 2000 John Wiley & Sons, Ltd.     

False memories of having said the unsaid: some new demonstrations

In a series of four studies, subjects who were naive as to the true purpose of the research were asked if they had said aloud things that, at most, they had only intended to say. Often, subjects reported (incorrectly) that they had said them. Specifically, the procedures involved: showing a series of phrases, each being followed by a command to say it aloud or not (Study 1); asking a series of questions, each being followed by a request to answer it aloud or not (Study 2); asking a series of questions in a public polling situation and interrupting the subject before one of the questions was answered (Study 3); and having each subject participate in a debate, during the course of which the participant was induced to plan to use a particular point, but was prevented from doing so (Study 4). Subjects were confident of such erroneous reports; they had a lower tendency to make such errors for material that had not actually been presented, and such errors depended upon certain details of the manner in which such ‘source-monitoring’ searches were initiated. © 1997 John Wiley & Sons, Ltd.     

Cyber-apostasy: its repercussions on Islam and interfaith relations*

In relations between Islam and the West, apostasy has been an issue of perennial contention. Although the Qur’ānic perspective on apostasy is ambiguous, the ?adīths and later Islamic legal thought prescribe harsh sanctions against apostasy, making repudiation of Islam extremely difficult, if not impossible, in the Muslim world. Such a coercive approach contravenes the Western value of freedom of conscience and the correlative right to religious freedom. Moreover, the rise of a parallel form of Islam—online- or cyber-Islam—has complicated the issue of apostasy even further. For countless Muslims worldwide, this parallel expression of their religion, although virtual, is even more ‘real’ than its offline, analogue expression. In this new Islamic expression, freedom of conscience can indeed be exercised. Online dissent, even to the point of engaging in ‘cyber-apostasy’ and encouraging others to do likewise, has given rise to a new level of reciprocity between Islam and other religions interacting with it in the ‘marketplace of religions’, thus opening a new chapter in the history of Islamic interaction with other faiths in the contemporary world.     

The dynamics of choice in a changing world: Effects of full and partial feedback

We explored the dynamics of choice behavior while the values of the options changed, unannounced, several times. In particular, choice dynamics were compared when the outcome values of all available options were known (full feedback) and when the outcome value of only the chosen option was known (partial feedback). The frequency of change, the values of the options, and the difference between them were also manipulated. In an experiment with N = 427, we found that the patterns of choices were different for the two levels of feedback. Whereas behavior in the full-feedback condition showed a tendency to switch choices following a missed opportunity—replicating previous findings—the behavior in the partial-feedback condition was different. It was sensitive to the outcome value of the chosen option in comparison to some memory of the last-experienced outcome value of the unchosen option. However, the comparison of these two values influenced choice behavior only when the outcome of the currently chosen option was satisfactory and the last outcome of the unchosen one was not. As expected, the other manipulated variables (change frequency, the options’ values, and the difference between them) had no effect on the dynamics of behavior.     

Dynamic Psychotherapy and the Problem of Time

This paper examines the dilemmas psychodynamic clinicians face in dealing with the challenges of the current clinical climate. We look to our theories, to the evolution of psychodynamic technique and to the collaborative nature of the therapeutic endeavor as they relate to the goals of psychotherapy. A case illustration is provided, and guidelines are offered for current professional practice.     

Visual-illusion distance paradoxes: A resolution

Several illusory phenomena are susceptible to explanations that invoke size scaling, but only if the distance estimates used to compute size are allowed to contradict the estimates of distance that are consciously experienced at the same time. However, such ??paradoxes?? make sense within Milner and Goodale??s (2006) two-stream theory of vision.     

Classifying personality disorders: an evolution-based alternative to an evidence-based approach

The study of personality disorders, no less psychology as a wole, remains divorced from broader spheres of scientific knowledge. Development of a conceptual schema for classifying personality disorders should include the examination of research limitations and inductive inconsistences that undermine the likely achievements of the evidential approach. An alternative course of action is outlined here, one that looks to evolutionary theory rather than evidence-based methods for classification guidance.     

Contrasting rule-based and similarity-based category learning: The effects of mood and prior knowledge on ambiguous categorization

This study adopts a dual-system view of category learning. The findings suggest that consumers who learn a dominant feature as a verbal rule for a product category will classify a new ambiguous product according to that feature even if it more closely resembles a different product category. The findings also demonstrate that dominant features can bias categorization toward a less prototypical category in the event that the new product breaks the rule. We refer to this phenomenon as criterial inferencing. Lastly, we offer unique empirical evidence to suggest that mood influences category learning and thus attenuates the criterial inferencing bias.
