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.     

Analogous selection processes in declarative and procedural working memory: N-2 list-repetition and task-repetition costs

Working memory (WM) holds and manipulates representations for ongoing cognition. Oberauer (Psychology of Learning and Motivation, 51, 45–100, 2009) distinguishes between two analogous WM sub-systems: a declarative WM which handles the objects of thought, and a procedural WM which handles the representations of (cognitive) actions. Here, we assessed whether analogous effects are observed when participants switch between memory sets (declarative representations) and when they switch between task sets (procedural representations). One mechanism assumed to facilitate switching in procedural WM is the inhibition of previously used, but currently irrelevant task sets, as indexed by n-2 task-repetition costs (Mayr & Keele, Journal of Experimental Psychology: General, 129(1), 4–26, 2000). In this study we tested for an analogous effect in declarative WM. We assessed the evidence for n-2 list-repetition costs across eight experiments in which participants switched between memory lists to perform speeded classifications, mental arithmetic, or a local recognition test. N-2 list-repetition costs were obtained consistently in conditions assumed to increase interference between memory lists, and when lists formed chunks in long-term memory. Further analyses across experiments revealed a substantial contribution of episodic memory to n-2 list-repetition costs, thereby questioning the interpretation of n-2 repetition costs as reflecting inhibition. We reanalyzed the data of eight task-switching experiments, and observed that episodic memory also contributes to n-2 task-repetition costs. Taken together, these results show analogous processing principles in declarative and procedural WM, and question the relevance of inhibitory processes for efficient switching between mental sets.     

The implicit cognition of reciprocal exchange: automatic retrieval of positive and negative experiences with partners in a prisoner's dilemma game

Models of reciprocity imply that cheater detection is an important prerequisite for successful social exchange. Considering the fundamental role of memory in reciprocal exchange, these theories lead to the prediction that memory for cheaters should be preferentially enhanced. Here, we examine whether information of a partner's previous behaviour in an interaction is automatically retrieved when encountering the face of a partner who previously cheated or cooperated. In two studies, participants played a sequential prisoner's dilemma game with cheaters and cooperative partners. Alternating with the game blocks, participants were asked to classify the smiling or angry facial expressions of cooperators and cheaters. Both experiments revealed congruence effects, reflecting faster identification of the smiles of cooperators (Experiments 1 and 2) and faster identification of the angry facial expressions of cheaters (Experiment 2). Our study provides evidence for the automatic retrieval of the partner's behaviour in the game, regardless of whether partners cheated or cooperated, and thus provides further evidence against the cheater detection hypothesis.     

How checking as a cognitive style influences working memory performance

Compulsive checking is known to influence memory, yet there is little consideration of checking as a cognitive style within the typical population. We employed a working memory task where letters had to be remembered in their locations. The key experimental manipulation was to induce repeated checking after encoding by asking about a stimulus that had not been presented. We recorded the effect that such misleading probes had on a subsequent memory test. Participants drawn from the typical population but who scored highly on a checking‐scale had poorer memory and less confidence than low scoring individuals. While thoroughness is regarded as a quality, our results indicate that a cognitive style that favours repeated checking does not always lead to the best performance as it can undermine the authenticity of memory traces. This may affect various aspects of everyday life including the work environment and we discuss its implications and possible counter‐measures. Copyright © 2010 John Wiley & Sons, Ltd.     

Do Suicides’ Characteristics Influence Survivors’ Emotions?

The suicide of a related person can often induce severe negative emotional reactions. The objective of this study was to explore the relationships between sociodemographic and diagnostic data of suicides and survivors' emotions and to close this substantial gap. The main outcome of this study was that survivors' severity of emotional disturbance was inversely correlated with age of suicides. In the multivariable approach, only age remained related to the majority of the assessed survivors' emotions, whereas other characteristics, such as gender, presence of psychiatric disorder, or suicide method were not associated with survivors' emotions. Age had a dominant impact on the relationship between suicides' characteristics and survivors' emotional reactions and supersedes the effect of most suicides' characteristics including diagnoses.     

Multiple Criteria Decision‐Making in Management Accounting and Control‐State of the Art and Research Perspectives Based on a Bibliometric Study

As an academic discipline as well as in practice, decision support is one of the most important functions of management accounting and control (MAC). Owing to decision settings' increasing complexity, suitable multiple criteria methods are becoming increasingly important for MAC. We, therefore, examine the extent to which certain multiple criteria decision‐making (MCDM) methods are used in the MAC context. In order to do so, we undertook an extensive bibliometric analysis of the management accounting field during the last three decades. The results indicate an increase in the importance of MCDM. Furthermore, recent research activities were classified into different areas of decision‐making within MAC since the majority of publications deal with the areas of strategic management, budgeting and performance management. More specifically, strategy and performance evaluation, strategic planning and the selection of alternatives are the most prominent MCDM applications. Our analysis reveals that the analytic hierarchy process (AHP) is the most popular analytical tool with which to support management in complex decision‐making situations. The results of the study prove that technical MAC literature does not cover a desirable range of MCDM applications and that the AHP, as well as the analytic network process (ANP) are of increasing importance in respect of the international scope of MAC. Therefore, the area of MCDM continues to be an active part of management science research and application, specifically of MAC. Copyright © 2011 John Wiley & Sons, Ltd.     

The Geneva affective picture database (GAPED): a new 730-picture database focusing on valence and normative significance

In emotional research, efficient designs often rely on successful emotion induction. For visual stimulation, the only reliable database available so far is the International Affective Picture System (IAPS). However, extensive use of these stimuli lowers the impact of the images by increasing the knowledge that participants have of them. Moreover, the limited number of pictures for specific themes in the IAPS database is a concern for studies centered on a specific emotion thematic and for designs requiring a lot of trials from the same kind (e.g., EEG recordings). Thus, in the present article, we present a new database of 730 pictures, the Geneva Affective PicturE Database, which was created to increase the availability of visual emotion stimuli. Four specific negative contents were chosen: spiders, snakes, and scenes that induce emotions related to the violation of moral and legal norms (human rights violation or animal mistreatment). Positive and neutral pictures were also included: Positive pictures represent mainly human and animal babies as well as nature sceneries, whereas neutral pictures mainly depict inanimate objects. The pictures were rated according to valence, arousal, and the congruence of the represented scene with internal (moral) and external (legal) norms. The constitution of the database and the results of the picture ratings are presented.     

On Minimizing Guessing Effects on Multiple‐Choice Items: Superiority of a two solutions and three distractors item format to a one solution and five distractors item format

Multiple‐choice response formats are troublesome, as an item is often scored as solved simply because the examinee may be lucky at guessing the correct option. Instead of pertinent Item Response Theory models, which take guessing effects into account, this paper considers a psycho‐technological approach to re‐conceptualizing multiple‐choice response formats. The free‐response format is compared with two different multiple‐choice formats: a traditional format with a single correct response option and five distractors (‘1 of 6’), and another with five response options, three of them being distractors and two of them being correct (‘2 of 5’). For the latter format, an item is scored as mastered only if both correct response options and none of the distractors are marked. After the exclusion of a few items, the Rasch model analyses revealed appropriate fit for 188 items altogether. The resulting item‐difficulty parameters were used for comparison. The multiple‐choice format ‘1 of 6’ differs significantly from the multiple‐choice format ‘2 of 5’, while the latter does not differ significantly from the free‐response format. The lower difficulty of items ‘1 of 6’ suggests guessing effects.
