Lack of free choice reveals the cost of multiple-target search within and across feature dimensions

Having to look for multiple targets typically results in switch costs. However, using a gaze-contingent eyetracking paradigm with multiple color-defined targets, we have recently shown that the emergence of switch costs depends on whether observers can choose a target or a target is being imposed upon them. Here, using a similar paradigm, we tested whether these findings generalize to the situation in which targets are specified across different feature dimensions. We instructed participants to simultaneously search for, and then fixate, either of two possible targets presented among distractors. The targets were defined as either two colors, two shapes, or one color and one shape. In one condition, only one of the two targets was available in each display, so that the choice was imposed. In the other condition, both targets would be present in each display, which gave observers free choice over what to search for. Consistent with our earlier findings, switch costs emerged when targets were imposed, whereas no switch costs emerged when target selection was free, irrespective of the dimension in which the targets were defined. The results are consistent with the operation of different modes of control in multiple-target search, with switch costs emerging whenever reactive control is required and being reduced or absent when displays allow for proactive control.     

Axiomatic Theories of Partial Ground I

This is part one of a two-part paper, in which we develop an axiomatic theory of the relation of partial ground. The main novelty of the paper is the of use of a binary ground predicate rather than an operator to formalize ground. This allows us to connect theories of partial ground with axiomatic theories of truth. In this part of the paper, we develop an axiomatization of the relation of partial ground over the truths of arithmetic and show that the theory is a proof-theoretically conservative extension of the theory PT of positive truth. We construct models for the theory and draw some conclusions for the semantics of conceptualist ground.     

Combining Value‐focused Thinking and Balanced Scorecard to Improve Decision‐making in Strategic Management

Goal orientation is key to strategic management. In this field, the Balanced Scorecard is one of the most widely used management tools. It structures a company's main objectives from different perspectives based on the strategy of the firm and uses performance indicators to measure the achievement of objectives and strategy. However, its method of creation is not theoretically sound. Value‐focused thinking is a decision‐making philosophy that fits perfectly with Balanced Scorecard creation. It provides methods and techniques for the identification and structuring of objectives that are suitable to systematically derive a scorecard from a means‐ends network. However, such a means‐ends network is often too complex for enduring use in strategic management. By adapting the network's structure to the Balanced Scorecard's layout, the profound and clear set of derived objectives and their measures serve as a reasonable basis for applying methods of multi‐criteria decision‐making in an organization. This paper aimed to outline a procedure that merges the Balanced Scorecard and value‐focused thinking by preserving each concept's strengths while eliminating their weaknesses. A six‐step process was developed theoretically and employed empirically in a case study. This process included (1) identifying objectives; (2) structuring objectives; (3) characterizing clusters of objectives; (4) formulating mission, vision, and strategy; (5) designing the scorecard; and (6) monitoring and adapting to change. On the basis of this approach, a Management Scorecard was produced that enabled strategy development and execution, put forth a clear and comprehensive means‐ends network, and visualized a company's most important objectives and their relationships structured through perspectives roughly following the Balanced Scorecard. It acts as a foundation for research to generalize and compare findings regarding goals of organizations. Our procedure demonstrates how scientific methods, such as value‐focused thinking, can yield benefits to practitioners' instruments, like the Balanced Scorecard, and how management tools can likewise improve scientific methods.

Children's comprehension of visual formal features in television programs

A review of previous studies on children's comprehension of visual formal features did not warrant predictions about children's understanding of the formal features as used in three items from Sesamstraat, the Dutch version of Sesame Street. Therefore, a study was designed in which 45 children in the age range of 4–6 years watched the items and were interviewed. In the first item, a split screen was used to visualize simultaneity of actions. The second item used a subjective camera to suggest the construction of a home video by one of the characters. Version 1 of this item did not show the character while making home video, whereas Version 2 did show the character while filming. The third item contained a dissolve (Version 1) or a cut (Version 2) to indicate the end of a dream. A general conclusion was that although older children (mean AGE=5.9 years) understood the visual formal features better than younger children (mean AGE=4.4 years), the extent to which children in both age groups understood the visual formal features appeared to vary between items and versions. Most children in both age groups understood the split screen in the first item. The younger age group did not understand the subjective camera if the making of the home video was not shown. Both the younger and the older age group understood the version with the cut better than the original version with the dissolve. In the discussion, the question was addressed what the findings of this study and previous studies teach us about children's understanding of visual formal features in general.     

Leadership predictors of innovation and task performance: Subordinates' self‐esteem and self‐presentation as moderators

This study examined self‐related subordinate variables as moderators of relationships between supervisors' leadership behaviours (transformational as well as active‐corrective transactional leadership) and subordinates' innovative behaviour and task performance. Based on behavioural plasticity and self‐monitoring theory, we hypothesized that these associations would be moderated by subordinates' organization‐based self‐esteem and by their propensity to modify self‐presentation, a major facet of the self‐monitoring construct. Field survey data (N=161) collected in research and development, marketing and human resources departments of several German companies revealed that transformational leadership positively predicted both criteria, whereas active‐corrective transactional leadership negatively predicted innovation. As hypothesized, transformational leadership related more strongly and positively to innovation for subordinates low in organization‐based self‐esteem. When subordinates were low in self‐presentation propensity, active‐corrective transactional leadership was negatively, and transformational leadership was positively associated with task performance.     

Three preparatory studies for promoting implementation of outpatient schema therapy for borderline personality disorder in general mental health care

ObjectiveThree studies were conducted to prepare for the implementation of Schema Therapy (ST) for Borderline Personality Disorder (BPD) in general mental healthcare settings. Two were surveys to detect promoting and hindering factors, one was a preliminary test of a training program in ST.MethodsIn 2004, a diagnostic analysis of factors promoting and hindering implementation of a new treatment for BPD was conducted among both managers (n = 23) and therapists (n = 49) of 29 Dutch mental healthcare institutes through a written survey (Study 1). Next, a training program, including a set of DVDs displaying the major therapeutic techniques, was developed and tested among eight therapists. The training program was evaluated by the participants. After the training, three independent raters evaluated therapists' adherence and competence, viewing videos of the therapists completing structured role-plays (Study 2). In 2008, a second written survey was conducted in 22 mental health institutes to study factors for future nationwide implementation of ST (Study 3).ResultsBoth surveys indicated that the situation in most institutes was favorable for implementing a new effective treatment, as participants were not satisfied with the existing treatments, had suitable professional backgrounds, worked in settings with (B)PD-oriented care programs, and expressed a need for change. The surveys yielded clear results for promoting or hindering successful implementation of ST. Promoting factors included scientific evidence for the effectiveness of the treatment, structural changes in the patient's personality, rapidly noticeable effects for the patient, low drop-out rates and a favorable cost-effectiveness. Possible barriers included implementation mandated unilaterally by management, choosing ST based on financial or organizational needs, extending implementation over a lengthy period of time and providing telephone support by therapists beyond office hours. The eight-day training program received very positive ratings. After the training, therapists were rated as sufficiently adherent and competent applying ST to treat BPD patients, with peer supervision and supervision recommended as a supplement to the training.ConclusionThis study showed that the situation in 2005 was advantageous to start implementation of ST. Evaluation of the training and the achieved competence scores of trainees concluded that the training program was a good basis for training therapists in ST. Outcome of the survey in 2008 demonstrated that there was a clear interest for implementation of ST for BPD patients in the future.     

Asymmetric Comparison in Choice Processes

Since Tversky's (1977) seminal paper on asymmetric comparisons was published, comparisons of different options are generally believed to be directional. Interestingly, the asymmetry involved in comparisons has not been considered systematically for choices between different options. This paper argues that, in decision situations, one of the options serves as a dominant standard against which the others are evaluated, which results in asymmetric comparisons and, in turn, has important and systematic consequences for the choice process. This paper outlines which conditions should result in asymmetric comparisons. Taking existing models of asymmetric comparisons into account, a process model will be presented using the loss of a previously available choice option as an example.     

Latent Classes of Dysregulated Behaviors Relate to Negative Mental Images

Dysregulated behaviors (DBs), such as self-harm or binge eating, are related to various negative outcomes. In this study, we investigate how classes of individuals vary in their level of DBs. We compare the classes with regards to their experiences regarding negative mental images and emotion regulation strategies. A web-based survey assessed eleven DBs in a sample of N=912 adults. A latent class analysis (LCA) identified a class of 168 adults that were prone to various DBs (“high(DBs)”). Another class (n?=?46) reported drunkenness and risks for drug use and overeating (“high(Intake)”). The majority of individuals (n?=?698) featured a low rate of DBs (“low(DBs)”). The high(DBs) exhibited the highest scores in distressing imagery and maladaptive emotion regulation. The high(Intake) had a low overall profile; however, it displayed increased imagery nowness. Class differences were leveled by depressive symptoms. The findings help extend the knowledge on DBs and their correlates. Clinical implications are discussed.     

The Role of Inference in Attribute Framing Effects

Previous research has shown that a speaker's choice between logically equivalent frames is influenced by reference point information, and that listeners draw accurate inferences based on the frame. Less clear, however, is whether these inferences play a causal role in generating attribute framing effects. Two experiments are reported, which suggest that frame‐dependent inferences are sufficient to generate attribute framing effects, and that blocking such inferences may block framing effects. Experiment 1 decomposed the typical framing design into two parts: One group of participants saw a target described in one of two attribute frames and reported their estimates (inferences) of the typical attribute value. These estimates were then given to a second group of yoked participants, who evaluated the target. Although this latter group was not exposed to different attribute frames, they nevertheless exhibited a “framing effect” as a result of receiving systematically different inferences. In contrast, Experiment 2 shows that experts—who are familiar with an attribute's distribution and are therefore less likely to draw strong frame‐based inferences—exhibit a diminished framing effect. Together, these findings underscore the role of inferences in the generation and attenuation of attribute framing effects. Copyright © 2017 John Wiley & Sons, Ltd.
