A New Model for Acquiescence at the Interface of Psychometrics and Cognitive Psychology

ABSTRACT

When measuring psychological traits, one has to consider that respondents often show content-unrelated response behavior in answering questionnaires. To disentangle the target trait and two such response styles, extreme responding and midpoint responding, Böckenholt (2012a Böckenholt, U. (2012a). Modeling multiple response processes in judgment and choice. Psychological Methods, 17, 665–678. doi:10.1037/a0028111[Crossref], [PubMed], [Web of Science ®] , [Google Scholar]) developed an item response model based on a latent processing tree structure. We propose a theoretically motivated extension of this model to also measure acquiescence, the tendency to agree with both regular and reversed items. Substantively, our approach builds on multinomial processing tree (MPT) models that are used in cognitive psychology to disentangle qualitatively distinct processes. Accordingly, the new model for response styles assumes a mixture distribution of affirmative responses, which are either determined by the underlying target trait or by acquiescence. In order to estimate the model parameters, we rely on Bayesian hierarchical estimation of MPT models. In simulations, we show that the model provides unbiased estimates of response styles and the target trait, and we compare the new model and Böckenholt’s model in a recovery study. An empirical example from personality psychology is used for illustrative purposes.     

The Concept of Experience by John Dewey Revisited: Conceiving, Feeling and ��Enliving��

The concept of experience by John Dewey revisited: conceiving, feeling and ??enliving??. Dewey takes a few steps towards a differentiation of the concept of experience, such as the distinction between primary and secondary experience, or between ordinary (partial, raw, primitive) experience and complete, aesthetic experience. However, he does not provide a systematic elaboration of these distinctions. In the present text, a differentiation of Dewey??s concept of experience is proposed in terms of feeling, ??enliving?? (a neologism proposed in this paper) and conceiving. Feeling refers to the basic mode of experience where action, emotion, cognition and communication constitute an original unity. Enliving, aesthetic experience, constitutes the lifeworld, as a person-in-world experience. Even though enliving is holistic and relational, a certain distance emerges between action, emotion and cognition which allows contemplation and choice. Conceiving, on the other hand, refers to the isolating and abstracting understanding of the world with even greater distance between action, emotion and cognition. Such a differentiation provides a clearer understanding of the scope of education. It avoids the risks of regressive tendencies in the concept of experience, and it helps to include conceiving within the realm of experience.     

Valuing clients' perspective and the effects on the therapeutic alliance: a randomized controlled study of an adjunctive instruction

The patterns of growth and development of the therapeutic alliance over the course of therapy have been of continued interest to psychotherapy researchers. The purpose of this study was to investigate whether a simple institutional metacommunication intervention with clients had an effect on the development of the alliance. This adjunctive instruction involved inviting therapy clients to take a proactive role in their treatment by encouraging feedback to their therapist about various aspects of the therapy process. In this randomized controlled study (N = 94), clients were assigned to 1 of 2 conditions: (a) an institutional adjunctive instruction condition in which patients were contacted by clinic personnel at the beginning of the remediation phase (Session 5) and encouraged to take a proactive role in their treatment and (b) a control condition that contained no institutional adjunctive instruction. Between-condition differences in the alliance were tested, controlling for baseline influences and the early therapeutic alliance. Clients' postsession reports from Sessions 1 to 24 indicated that the adjunctive instruction increased the alliance over the course of therapy vis-à-vis the control condition. The adjunctive instruction appeared to have fostered clients' evaluation of their therapists' interest in their welfare. The results indicate that interventions, even brief or subtle, can produce lasting benefits in the alliance when targeted at specific psychological processes. Systematic metacommunication from the institutional level appeared to reinforce clients' therapeutic alliance with their therapists in individual treatment.     

Psychophysical saturation scales and the spectral sensitivity in human vision

Summary For mixtures of white and colored lights, the intensity of the colored light necessary to produce a linear psychophysical saturation curve is determined. This intensity may be defined as equilibrium between chromatic and achromatic excitation. From a measurement of the equilibrium throughout the spectrum, a spectral sensitivity function may be derived. According to the hypothesis of Börsken and Hemminger (1980), this function describes the spectral sensitivity of the achromatic channel in human color vision.     

Emotion-regulation skills as a treatment target in psychotherapy

Background

Deficits in emotion-regulation skills have been shown to be integral to the development and maintenance of a wide range of mental disorders.

Aim

To evaluate the importance of these skills as a treatment target in psychotherapeutic interventions.

Method

Nine specific emotion-regulation skills were assessed in a sample of 289 inpatients before and after cognitive-behavioural treatment. Self-reports of success in pretreatment skills application were first compared to those of 246 non-clinical controls. Pretreatment skills application and change in skills application during therapy were then related to a variety of outcome measures. Finally, the effects of integrating a brief training of general emotion-regulation skills into the CBT-based treatment were evaluated in a controlled trial.

Results

Uni- and multivariate analyses identified the skills of acceptance, tolerance, and active modification of negative emotions as particularly important for current mental health and treatment outcome. Replacing parts of the standard CBT treatment with the emotion-regulation training enhanced the effects of the CBT treatment on skills application and on other measures of mental health.

Conclusion

Incorporating interventions that directly target general emotion-regulation skills may improve the effectiveness of psychotherapeutic interventions.     

Discretionary task interleaving: heuristics for time allocation in cognitive foraging

When participants allocated time across 2 tasks (in which they generated as many words as possible from a fixed set of letters), they made frequent switches. This allowed them to allocate more time to the more productive task (i.e., the set of letters from which more words could be generated) even though times between the last word and the switch decision ("giving-up times") were higher in the less productive task. These findings were reliable across 2 experiments using Scrabble tasks and 1 experiment using word-search puzzles. Switch decisions appeared relatively unaffected by the ease of the competing task or by explicit information about tasks' potential gain. The authors propose that switch decisions reflected a dual orientation to the experimental tasks. First, there was a sensitivity to continuous rate of return--an information-foraging orientation that produced a tendency to switch in keeping with R. F. Green's (1984) rule and a tendency to stay longer in more rewarding tasks. Second, there was a tendency to switch tasks after subgoal completion. A model combining these tendencies predicted all the reliable effects in the experimental data.     

Health-Related Quality of Life is Associated with Positive Affect in Patients with Coronary Heart Disease Entering Cardiac Rehabilitation

Health-related quality of life (QoL) is an important and widely used outcome measure in cardiac populations. We examined the relationship between positive affect and health-related quality of life, controlling for traditional cardiovascular risk factors, clinical variables and negative affect. We further investigated the role of gender in this relationship given the well-known gender differences in cardiovascular health. We enrolled 746 patients with coronary heart disease (CHD) before they entered outpatient cardiac rehabilitation. All patients completed the Global Mood Scale and the SF-36 Health Survey. Positive affect was independently associated with mental (p < .001) and physical QoL (p < .001) after controlling for control variables. Gender moderated the relationship between positive affect and physical QoL (p = .009) but not mental QoL (p = .60). Positive affect was positively associated with physical QoL in men (p < .001) but not in women (p = .44). The health-related QoL of patients with CHD is associated with a person’s level of positive affect.     

Color sensation of normal and anomalous trichromats measured by magnitude estimation

Summary Colors perceived by normal, protanomalous, and deuteranomalous trichromats were scaled by magnitude estimation. As a result, opponent-colors functions were obtained which show the hue sensations produced by spectral lights. For color-normal observers, the loci of maximal hue sensations were different in some aspects from those expected from current opponent-colors theories.The results obtained from the anomalous observers confirm the view that the causes of prot- and of deuteranomalous vision consist in reverse shifts of the long- and middle-wavelength cone sensitivities respectively. It was found that anomalous trichromats perceive less red in the violet spectrum than do normal subjects. This finding may be explained by the hypothesis that short-wave-length red is produced by a secondary maximum of the long-wavelength cone excitation. In the experiment, the main defect of anomalous trichromats, compared with normal subjects, consisted in the high instability of hue perception and hue recognition. This instability may be explained by an unfavorable signal/noise relation created by the similarity of the two long-wavelength receptor sensibilities in the anomalous red/green systems.     

Saturation of light mixtures as a function of chromatic and achromatic excitation in the visual system

Summary The saturation of mixtures of white and chromatic lights may be measured by magnitude estimation as a function of the proportion of chromatic light in the mixture. When the intensity of the white light is kept constant, and the intensity of the chromatic light is varied, the psychophysical saturation curves change in a regular way: With higher chromatic intensity, they become less convex, and finally turn concave. Therefore it is possible to measure a whole class of stimulus-response curves representing the relation of chromatic light proportion to saturation. In this paper, a hyperbolic function is developed to describe this class of curves. The function is based upon the assumption that the data-processing system of human color vision evaluates the proportion of chromatic and achromatic excitation to produce subjective saturation. This assumption is in accordance with the known constancy of color perception under natural viewing conditions. The experimental data are approximated just as well, and in some cases better, by the hyperbolic function than by the commonly used power function.
