Why positive information is processed faster: the density hypothesis

The authors postulate and show a speed advantage in the processing of positive information and hypothesize that this advantage is caused by the higher density of positive information in memory: Positive information is more similar to other positive information, in comparison with the similarity of negative information to other negative information. This "density" hypothesis is supported by multidimensional scaling of evaluative stimuli and response latency experiments. The relevance and explanatory power of the hypothesis is demonstrated by secondary data analyses of prior research in the evaluative priming paradigm. The final discussion is concerned with further theoretical implications of the density hypothesis, its generality and limitations, and its relation to other theoretical conceptions and applications.     

Conflict over emotional expression: implications for interpersonal communication

The current study examined the role of conflict over emotional expression for subjective and interpersonal functioning. The Ambivalence Over the Expression of Emotion Questionnaire (AEQ) was administered to female students who were videotaped while engaging in a conflict-resolution and feedback task with their boyfriends. External ratings showed ambivalent women to be less positive in their verbal statements and to be more constricted in their nonverbal expressions. When mood and other personality constructs were controlled for, ambivalence entailed greater overt submissiveness. Ambivalent women also displayed lower congruence between their verbal and nonverbal communication, irrespective of depression and other personality variables. These data suggest that conflict over emotional expression entails less congruent communication, less positivity in close relationships, and a subordinate stance for the ambivalent individual.     

Consumption systems: Unveiling bi-residential and delegated consumption

Based on an exploratory study of 29 semi-structured interviews followed by a grounded theory analysis, this research explores the circulation of local products and brands enacted by bi-residential consumers with geographically dispersed networks across two places. The results show that two new consumption systems are emerging at the frontier between conventional and collaborative consumption: bi-residential and delegated consumption. In these two consumption systems, the bi-residential consumer mediates the relationship between the retailer and the final consumer, thus informally extending the retailer's downstream value chain. Bi-residential and delegated systems partly overlap but also differ from conventional or collaborative consumption systems in two ways: (a) they are linked in a modelized process sustained by the perception of ‘access’ and the ‘logistic role’ of the bi-residential consumer; (b) they are embedded in a hybrid exchange system intertwining gift-giving and monetary exchange. These consumption systems occur at the interstice between conventional and collaborative consumption. Local retailers and brands could benefit from knowledge in this area with a view to opening up new opportunities in value co-creation with bi-residential consumers.     

A Mixed λ-calculus

The aim of this paper is to define a λ-calculus typed in aMixed (commutative and non-commutative) Intuitionistic Linear Logic. The terms of such a calculus are the labelling of proofs of a linear intuitionistic mixed natural deduction NILL, which is based on the non-commutative linear multiplicative sequent calculus MNL [RuetAbrusci 99]. This linear λ-calculus involves three linear arrows: two directional arrows and a nondirectional one (the usual linear arrow). Moreover, the -terms are provided with seriesparallel orders on free variables. We prove a normalization theorem which explicitly gives the behaviour of the order during the normalization procedure.

Emotion regulation through listening to music in everyday situations

Music is a stimulus capable of triggering an array of basic and complex emotions. We investigated whether and how individuals employ music to induce specific emotional states in everyday situations for the purpose of emotion regulation. Furthermore, we wanted to examine whether specific emotion-regulation styles influence music selection in specific situations. Participants indicated how likely it would be that they would want to listen to various pieces of music (which are known to elicit specific emotions) in various emotional situations. Data analyses by means of non-metric multidimensional scaling revealed a clear preference for pieces of music that were emotionally congruent with an emotional situation. In addition, we found that specific emotion-regulation styles might influence the selection of pieces of music characterised by specific emotions. Our findings demonstrate emotion-congruent music selection and highlight the important role of specific emotion-regulation styles in the selection of music in everyday situations.     

Typical Intellectual Engagement and Cognition in Old Age

ABSTRACT

Typical Intellectual Engagement (TIE) comprises the preference to engage in cognitively demanding activities and has been proposed as a potential explanatory variable of individual differences in cognitive abilities. Little is known, however, about the factorial structure of TIE, its relations to socio-demographic variables, and its influence on intellectual functioning in old age. In the present study, data of 364 adults (65–81 years) from the Zurich Longitudinal Study on Cognitive Aging (ZULU) were used to investigate the factorial structure of TIE and to examine the hypothesis that TIE is associated more strongly with crystallized intelligence than with fluid intelligence in old age. A measurement model of a second order factor based on a structure of four correlated first order factors (Reading, Problem Solving, Abstract Thinking, and Intellectual Curiosity) evinced an excellent fit. After controlling for age, sex, and formal education, TIE was more strongly associated with crystallized intelligence than with fluid intelligence, comparable to results in younger persons. More detailed analyses showed that this association is mostly defined via Reading and Intellectual Curiosity.     

Self‐Concept Clarity and the Management of Social Conflict

ABSTRACT: In 4 studies we examined the relationship between self‐concept clarity and conflict management. Individuals with higher self‐concept clarity were overall more active and showed more cooperative problem‐solving behavior than people with low self‐concept clarity. There were no relationships with contending or yielding. The positive relationship with cooperative behavior was mediated by less rumination (Study 2) and moderated by conflict intensity (Study 3). Specifically, it applied to relatively mild conflicts (Study 3). Finally, Study 4 extended these findings to the group level: Dyad members with higher self‐concept clarity engaged in problem solving, whereas dyad members with lower self‐concept clarity did not. We conclude that higher self‐concept clarity associates with proactive problem solving in social conflict.     

The Role of Familial Incarceration and Ethnic Identity in Suicidal Ideation and Suicide Attempt: Findings from a Longitudinal Study of Latinx Young Adults in California

Suicide is a leading cause of death among young adults; however, contextual risks and cultural factors are rarely studied in the context of ethnic minority suicidal ideation (SI) and suicidal attempt (SA). This study assessed the association between familial incarceration and suicide behaviors and examined ethnic identity as a potential moderator. Data from a longitudinal study of health among Hispanics (n = 1,094) in California were used to test associations between familial incarceration, ethnic identity, and SA and SI, adjusting for demographic factors and covariates. Approximately 18% and 8% of respondents reported SI and SA, respectively. Compared to no incarceration, or the incarceration of a relative, parental incarceration was associated with higher odds (AOR: 2.09, 95% CI: 1.23–3.34) of SI whereas higher affective ethnic identity reduced the odds (AOR: 0.52, 95% CI: 0.31–0.89) of SA. Ethnic identity moderated the association between parental incarceration and SI (AOR: 0.33, 95% CI: 0.13–0.79). Incarceration of a family member can set the stage for exclusion from critical institutions and can have long‐term consequences for adult mental health. Promoting a positive ethnic identity may be a promising prevention strategy that could bolster resilience among at‐risk, urban minority youth.     

Relationships between early and final reports of treatment outcome in long-term group psychotherapy

A study of the report of treatment outcome in three long-term therapy groups focused on two questions: 1) Are early reports of treatment outcome significantly related to final reports, i.e., is there substantial consistency in outcome reports over the course of therapy? 2) Are final reports of treatment outcome significantly more favorable than early reports, i.e., do patients experience significant improvement after the early part of therapy? Affirmative answers to these two questions for a number of outcome variables led to a consideration of a number of clinical and research implications.
