What is adaptive about adaptive decision making? A parallel constraint satisfaction account

There is broad consensus that human cognition is adaptive. However, the vital question of how exactly this adaptivity is achieved has remained largely open. Herein, we contrast two frameworks which account for adaptive decision making, namely broad and general single-mechanism accounts vs. multi-strategy accounts. We propose and fully specify a single-mechanism model for decision making based on parallel constraint satisfaction processes (PCS-DM) and contrast it theoretically and empirically against a multi-strategy account. To achieve sufficiently sensitive tests, we rely on a multiple-measure methodology including choice, reaction time, and confidence data as well as eye-tracking. Results show that manipulating the environmental structure produces clear adaptive shifts in choice patterns – as both frameworks would predict. However, results on the process level (reaction time, confidence), in information acquisition (eye-tracking), and from cross-predicting choice consistently corroborate single-mechanisms accounts in general, and the proposed parallel constraint satisfaction model for decision making in particular.     

Moral disengagement moderates the predicted effect of trait self‐control on self‐reported aggression

An increasing number of studies reveal that self‐control is an important preventative factor for aggression. However, the involvement of potential explanatory variables has received less research attention. Drawing upon the feedback‐loop model of self‐control, the current research assumed that the preventing effect of trait self‐control on aggression may be moderated by moral disengagement. Self‐reported measures of trait self‐control, moral disengagement and aggression were administered to 946 Chinese university students. Results show that trait self‐control had a negative effect on physical aggression, verbal aggression, anger and hostility, whereas moral disengagement positively predicted each of these constructs. Of particular importance was a significant interaction between trait self‐control and moral disengagement for verbal aggression and hostility. Specifically, the preventing effect of trait self‐control on these two types of aggression was more pronounced in individuals with low rather than high moral disengagement. In conclusion, low conditional endorsement of transgressive acts and having high trait self‐control are both important individual‐difference variables that explain reduced aggression.     

Academic self-concept of ability and cortisol reactivity

The present study aimed to clarify the relationship between a school-specific trait (academic self-concept of ability [ASCA]) and hormonal stress response by using a trait-compatible stressor (test). First, we determined 52 students' ASCA scores for biology and measured their salivary cortisol concentration before and after a biology test (experimental group, n = 28) or a free writing task (control group, n = 24). For participants who took the test, statistical analysis indicated a significant negative correlation between ASCA score and cortisol response. In contrast, the control group showed a decrease in cortisol concentrations between test times and no correlation between cortisol concentration and ASCA scores were found. These findings indicated an interaction between ASCA scores and hormonal stress response when an academic-related stressor is present. Furthermore, these variables might influence each other adversely: high cortisol concentrations during a test situation may lead to greater feelings of insecurity, resulting in low ASCA scores and awareness of these low scores may lead to a further increase in cortisol, creating a vicious cycle.     

Trait anxiety reduces affective fading for both positive and negative autobiographical memories

The affect associated with negative events fades faster than the affect associated with positive events (the Fading Affect Bias; the FAB). The research that we report examined the relation between trait anxiety and the FAB. Study 1 assessed anxiety using the Depression, Anxiety, and Stress Scale; Studies 2 and 3 used the Beck Anxiety Inventory. Studies 1 and 2 used retrospective procedures to probe positive event memories and negative event memories while Study 3 used a diary procedure. The results of all 3 studies showed that increased anxiety was associated with both a lowered FAB and lower overall affect fading for both positive events and negative events. These results suggest that for people free of trait anxiety, the FAB reflects the operation of a healthy coping mechanism in autobiographical memory that is disrupted by trait anxiety.     

Who Turns Green with Envy? Conceptual and Empirical Perspectives on Dispositional Envy

Previous research has conceptualized dispositional envy as a general construct that does not vary across comparison domains. In five studies (N = 1393), we examine dispositional envy as a domain‐specific construct. In Study 1, we present the development of a domain‐specific measure of dispositional envy. Across samples from different populations and two countries (Studies 2 and 3), the measure is shown to have good reliability, construct validity and stability over three months, highlighting the trait‐like character of the construct. State levels of envy were also examined in the academic domain (Study 4) and in dyadic interactions between unacquainted participants (Study 5). Results show a Person × Situation Interaction effect (i.e. Dispositional Envy × Situation) on experiences of envy. By placing domain‐specific dispositional envy into a network of similar and dissimilar constructs, the current findings serve as a foundation for drawing conclusions about the nature of dispositional envy.

Testing for DIF in a model with single peaked item characteristic curves: The parella model

The PARELLA model is a probabilistic parallelogram model that can be used for the measurement of latent attitudes or latent preferences. The data analyzed are the dichotomous responses of persons to items, with a one (zero) indicating agreement (disagreement) with the content of the item. The model provides a unidimensional representation of persons and items. The response probabilities are a function of the distance between person and item: the smaller the distance, the larger the probability that a person will agree with the content of the item. This paper discusses how the approach to differential item functioning presented by Thissen, Steinberg, and Wainer can be implemented for the PARELLA model.

当代西方道德人格研究的两类取向

道德人格研究是西方道德心理学的新主题,主要有两类取向：特质取向和社会认知取向。特质取向把道德人格理解为与道德有关的人格特质,对道德榜样的自然概念和真实道德榜样的人格特征进行了大量研究。社会认知取向以社会认知图式、知识结构和认知－情感机制来解释道德人格,揭示了个体内部动态的心理过程。未来的道德人格研究要强调两类取向的结合,加强发展过程和影响因素研究,并注重多水平与多学科的整合。

Trait anxiety and attenuated negative affect differentiation: a vulnerability factor to consider?

Background and Objectives: Describing emotional experiences using distinct terms, or affect differentiation, has been associated with emotion regulation and adaptive behavior under stress. There is little data, however, examining the association between differentiation and dispositional factors underlying psychopathology. The current study examines the association between differentiation and trait anxiety (TA) given prior evidence of cognitive biases in TA relevant to higher order processing of emotional experiences.

Design: We examined cross-sectionally, via lab-based repeated assessment, the association between differentiation of negative and positive experiences and TA.

Methods: Two hundred twenty-two adults completed an emotion reactivity task including repeated assessments of affect. We hypothesized that individuals higher in trait anxiety (HTA) would have greater difficulty differentiating their experiences.

Results: HTA individuals exhibited lower levels of negative affect (NA) differentiation even when controlling for depression. Although negative emotion intensity was consistently associated with lower differentiation, this did not account for the influence of HTA on differentiation.

Conclusions: These data suggest that HTA individuals have greater difficulty differentiating negative emotions, regardless of negative emotion intensity and depression. As HTA is common to many emotional disorders; this evidence suggests that poor differentiation may also be an important transdiagnostic consideration in models of risk and of affective disease.
