Order effects in sequentially judged options due to the direction of comparison

Many real-world judgment tasks present options in sequence. Typically, these judgments are made step-by-step, immediately after considering each option, or end-of-sequence, after all have been seen. We report similar order effects in both procedures, due to direction of comparison. It appears that judges form an impression of each new option by comparing it to those that preceded it. Using that option’s features as a “checklist,” more weight is given to unique ones than to ones shared with previous options. This unidirectional comparison process produces increasing ratings in options with unique positive features, and decreasing ratings when options have unique negative features. By manipulating the barriers to making multiple comparisons, we show that the direction-of-comparison effect is not limited to judgment tasks with sequential presentation. Even simultaneously presented options may show order effects, if they are judged one at a time—in sequence. Possible explanations and implications are discussed.     

On the positive and negative effects of self-efficacy on performance: Reward as a moderator

We address the controversy regarding the sign of the effect of self-efficacy on performance. We propose that when reward is high, self-efficacy has a positive effect on performance, whereas when reward is low, it has a negative effect. This hypothesis was tested in three experiments (with sample sizes of 76, 99, and 111) in which reward and self-efficacy were manipulated and performance was measured using different manipulations and tasks in both within-factor and between-factor designs. The results supported the hypothesis that reward moderates the effect of self-efficacy on performance. When reward was high, the effect of self-efficacy on performance was positive, whereas when reward was low, the effect of self-efficacy on performance was negative.     

Quantity recognition among speakers of an anumeric language

Recent research has suggested that the Pirahã, an Amazonian tribe with a number‐less language, are able to match quantities > 3 if the matching task does not require recall or spatial transposition. This finding contravenes previous work among the Pirahã. In this study, we re‐tested the Pirahãs’ performance in the crucial one‐to‐one matching task utilized in the two previous studies on their numerical cognition, as well as in control tasks requiring recall and mental transposition. We also conducted a novel quantity recognition task. Speakers were unable to consistently match quantities > 3, even when no recall or transposition was involved. We provide a plausible motivation for the disparate results previously obtained among the Pirahã. Our findings are consistent with the suggestion that the exact recognition of quantities > 3 requires number terminology.     

Resistance to extinction of human evaluative conditioning using a between‐subjects design

Surprise has been described in various contexts as a neutral, a positive, or a negative emotion. Six experiments are reported in which surprise ratings of unexpected positive and negative outcomes, with identical prior probabilities, were compared. For unexpected occurrences of events that are beyond the control of the protagonist, successes were consistently perceived as more surprising than failures. For unexpected action controlled outcomes for which the protagonist was partly responsible, failures were rated as more surprising than successes. The findings are interpreted as being due to an implicit contrast between out-of-control situations and success, in the first case, and between goal-directed efforts and failure, in the second.     

Two-Component Solutions of Repertory Grid Data: A Comparison of Three Methods

Abstract

Of the various ways in which repertory grid data can be summarized, the two-component plot has been the most popular method. These plots are derived in three main ways: (1) Slater's (1977) INGR1D program, (2) subprogram FACTOR in the Statistical Package for the Social Sciences (SPSS) (Nie, Hull, Jenkins, Steinbrenner, & Brent, 1975), and (3) Higgenbotham and Bannister's (1983) CAB program, little attempt has been made to compare the solutions produced by these programs despite widespread use. A small number of single case studies suggest that the solutions are comparable. This paper reports a study that compares the solutions derived from INGRID, SPSS, and CAB for a series of cases. The results show that correspondence was good for the first components, but for the second components the results were less satisfactory     

Is this problem likely to be solved? A cognitive schema of effective problem solving

The present study tested the existence of a cognitive schema that guides people's evaluations of the likelihood that observed problem-solving processes will succeed. The hypothesised schema consisted of attributes that were found to distinguish between retrospective case reports of successful and unsuccessful real world problem solving (Lipshitz & Bar Ilan, 1996 Lipshitz, R. and Bar Ilan, O. 1996. How problems are solved: Reconsidering the phase theorem. Organisational Behaviour and Human Decision Processes, 45: 48–60.  [Google Scholar]). Participants were asked to evaluate the likelihood of success of identical cases of problem solving that differed in the presence or absence of diagnosis, the selection of appropriate or inappropriate solutions, and the pairing of diagnosis with appropriate or non-appropriate solutions. Consistent with the proposition, diagnosis affected perceived likelihood of success, albeit only when solution quality was held constant, and appropriate diagnosis with a compatible solution produced higher perceived likelihood of success than appropriate diagnosis with incompatible solutions. In addition, results showed that solution quality played a significant role, and that compatibility with a six-phase rational model of problem solving played no role in judging likelihood of success.     

THE JEWISH LEGIONS IN THE FIRST WORLD WAR AS A LOCUS OF IDENTITY FORMATION

Based on life‐writing material, this article sheds light on the process by which the Jewish Legions in the British Army in the First World War, composed in large part of Jewish volunteers from Canada and the United States, contributed to the development among its legionnaires of a sense of belonging to their respective North American countries. The notion that formerly displaced immigrants were fighting for the Promised Land, and the consistency of this notion with the overall aims of the allies in the First World War, promoted the development of a unique identity as Jewish “citizen‐soldiers”.     

The Hidden Cost of Insurance on Cooperation

A common solution to mitigate risk is to buy insurance. Employing the trust game, we find that buying insurance against the risk of betrayal has a hidden cost: trustees are more likely to act opportunistically when trustors choose to be insured against the breach of trust. Supposedly, trustees are less likely to cooperate when trustors buy insurance because choosing insurance implicitly signals that the trustor expects the trustee to behave opportunistically, paradoxically encouraging trustees not to cooperate. These results shed new light on the potential drawbacks of financial safeguards that are intended to minimize the risky nature of trust taking: the presumed safeguard against the risk of betrayal may, under certain circumstances, increase the probability of betrayal.
