Determinants of the magnitude of willingness to accept relative to willingness to pay

In this paper we test two hypotheses that stem from the work of Mellers, Chang, Birnbaum and Ordonez ( 1992 ). The first hypothesis is that in a binary gamble, the ratio of WTA to WTP is decreasing in the probability attached to a nonzero event. The second hypothesis is that this ratio is independent of the size of stakes. We find support for the first hypothesis, but mixed support for the second. The second hypothesis holds in the case of gains, but not in the case of losses. Copyright © 2001 John Wiley & Sons, Ltd.     

From Freud to Gehrig to Rapaport to DiMaggio

Lacking the size, talent, and speed to play shortstop for the New York Yankees, I chose instead to become a psychologist/psychoanalyst. Yet, baseball and psychoanalysis share much in common. Each is played in the inner diamonds of one's mind, values the past and what is passing, and requires a strong work ethic. Both are timeless and involve an almost boring leisureliness between occasional moments of crisis. Then too, each calls for an attitude of consistency and patience and a responsibility to do one's best. From my parents and brother to my wife and son and his family, from my teachers and supervisors to my colleagues, and from Menninger to the Society for Personality Assessment (SPA), I feel deeply grateful for the partners and teammates I have and have had.     

Psychophysics of remembering: to bias or not to bias

Delayed matching to sample is typically a two-alternative forced-choice procedure with two sample stimuli. In this task the effects of varying the probability of reinforcers for correct choices and the resulting receiver operating characteristic are symmetrical. A version of the task where a sample is present on some trials and absent on others is analogous to a yes/no recognition task. We describe data from two experiments where an asymmetry in performance in the yes/no task could be attributed to a change in response bias with increasing retention-interval duration from a matching-law perspective, but not from a signal-detection perspective. Both approaches make explicit assumptions about response bias. The apparent inconsistency between the two approaches to the treatment of response bias is resolved in terms of a model proposed by K. G. White and J. T. Wixted (1999) which predicts asymmetrical matching-law functions and receiver operating characteristics without making any assumptions about response bias.     

Consequences of allocating attention to locations and to other attributes

Simple reaction time to a light target may be lengthened when the light is preceded by a nonin-formative s timulus at the same location. This is known asinhibition of return. Does inhibition of return result if the relation between successive stimuli is defined in terms of color or orientation? Subjects pressed a key when a small square was displayed. In Experiments 1–3, location and color of the square were manipulated; there was inhibition of return based on location, but not on color. In Experiments 4–5, a confounding of color and luminance was eliminated, with no change in results. In Experiments 6–7, the background was composed of vertical stripes and the squares were composed of left- or right-oriented diagonal stripes. There was evidence of inhibition of return based on location, but not on orientation. These data support the idea that location is processed differently from other features.     

Psychological Consequences of Failing to Attribute Negative Outcomes to Discrimination

The present research examines the psychological consequences of not making attributions to discrimination in response to negative feedback. In two studies, 100 and 80, respectively, female undergraduates at large US research universities were exposed to conditions that simulated three distinct reasons for not making an attribution to discrimination which parallel three theoretical information processing stages. The psychological consequences examined included changes in activation of and explicit thoughts about sexism, affective state, excuses for poor performances, and negative attitudes toward the perpetrator. Results illustrated that there are psychological consequences of failing to make an attribution to discrimination, and that the three ways to fail to make an attribution to discrimination are distinct in that each resulted in unique consequences.     

How to Respond to the Problem of Deviant Formal Causation

Recently, a new problem has arisen for an Anscombean conception of intentional action. The claim is that the Anscombean’s emphasis on the formally causal character of practical knowledge precludes distinguishing between an aim and a merely foreseen side effect. I propose a solution to this problem: the difference between aim and side effect should be understood in terms of the familiar Anscombean distinction between acting intentionally and the intention with which one acts. I also argue that this solution has advantages over an alternative that has already been endorsed in the literature: it is a better fit for the Anscombean theory, and it naturally accommodates intuitions about the moral significance of aiming vs. merely foreseeing.     

Transfer of pigeons' matching to sample to novel sample locations

This study examined the conditions under which conditional stimulus control by the sample stimuli in three-key matching-to-sample paradigms would generalize across the different possible sample locations. In Experiments 1 and 2, the samples appeared on the left and right side keys during initial training and then on the center key during testing. Transfer of pigeons' matching performances to the center-key samples was evident after both identity and symbolic matching training. In Experiment 3, pigeons trained on symbolic matching with two side-key samples or with a side-key and a center-key sample generally transferred their learned matching performances to those samples when they subsequently appeared in the remaining (novel) location. These results indicate that, when two-choice conditional discriminations are learned with more than one sample location, the visual characteristics of the sample per se predominantly come to control the pigeons' comparison choices. This finding encourages the use of the multiple-location training procedure as a way of reducing control by location, thus providing a more discriminating test of symmetry in animals.     

Comparison of dual discrepancy criteria to assess response to intervention

Much of the research regarding diagnosing children as LD with responsiveness-to-intervention (RTI) has examined methods to identify children as non-responsive. The current study examined the dual discrepancy (DD) definition in which children score low on a post-intervention reading measure and score below their peers in reading growth rates. Four definitions of DD were compared, student growth below the 25th percentile, 33rd percentile, 50th percentile, and less than one standard deviation below the mean. Participants were 151 children in grades 1 through 3 who were identified as experiencing reading difficulties. Results suggested that the three percentile groups significantly differentiated reading scores between DD and non-DD children, but the one standard deviation group did not. No ethnic or gender biases were noted and the 25th and 33rd percentile criteria closely matched estimates of LD prevalence. Implications for future research are included.     

Reactions to Receiving Aid as a Function of Cost to Donor and Opportunity to Aid1

Drawing on equity theory, two possibilities that might reduce resentment of the donor following the receipt of aid which cannot be repaid were investigated: (a) the cost to the donor is minimized, and (b) the recipient has an opportunity to aid a third party. The results provide evidence that the recipient will like the donor less and be less willing to request future aid when he cannot repay the aid than when he can. Weak support was received by the hypothesis that the tendency to like the donor less when the aid cannot be repaid will be stronger, the greater the perceived cost. Support was found for the hypothesis that the decreased willingness to request future aid when the aid cannot be repaid will be stronger, the greater the perceived cost. Support was found for the hypotheses that the recipient will like the donor more and be more willing to request future aid when he has an opportunity to aid a third party than when he cannot aid anyone.     

Contributions of longitudinal research to a cognitive theory of adjustment to aging

In agreement with Costa and McCrae (1992), the principle of ‘multiple uses’ of longitudinal studies is stressed based on a comparative review of the history of the Berkeley longitudinal studies and their different uses, and of those of the Bonn Longitudinal Study on Aging (BOLSA). Of the many uses of BOLSA, its contribution to the testing of a cognitive theory of aging is discussed. A selection of the findings of BOLSA and other studies of the Bonn Department of Psychology and the Institute of Gerontology, University of Heidelberg, is reported. These findings support three postulates of this theory: ( 1 ) the perceived rather than the objective situation directs behaviour; (2) perceptions of situations are related to dominant concerns of the person; and (3) adjustment to aging is achieved when a balance between the cognitive and motivational systems of the person has been attained.     

From Atheism to Theodicy to Intelligent Design: Responding to the Work of Francisco J. Ayala

This article responds to a few of the major themes found in the work of Francisco Ayala. The author praises Ayala for strongly challenging the assumptions of many contemporary atheists, like Richard Dawkins, who believe that the scientific method can be used in service of scientistic conclusions. The author then goes on to examine Ayala's understanding of the relationship between science and religion. Finally, the author asks critical questions about Ayala's contributions to the theodicy problem and the critique of Intelligent Design.
