Exploring relations between task conflict and informational conflict in the Stroop task

In this study, we tested the proposal that the Stroop task involves two conflicts—task conflict and informational conflict. Task conflict was defined as the latency difference between color words and non-letter neutrals, and manipulated by varying the proportion of color words versus non-letter neutrals. Informational conflict was defined as the latency difference between incongruent and congruent trials and manipulated by varying the congruent-to-incongruent trial ratio. We replicated previous findings showing that increasing the ratio of incongruent-to-congruent trials reduces the latency difference between the incongruent and congruent condition (i.e., informational conflict), as does increasing the proportion of color words (i.e., task conflict). A significant under-additive interaction between the two proportion manipulations (congruent vs. incongruent and color words vs. neutrals) indicated that the effects of task conflict and informational conflict were not additive. By assessing task conflict as the contrast between color words and neutrals, we found that task conflict existed in all of our experimental conditions. Under specific conditions, when task conflict dominated behavior by explaining most of the variability between congruency conditions, we also found negative facilitation, thus demonstrating that this effect is a special case of task conflict.     

An immunochemical approach to model and long-term suppression of depressive and anxiety behavior

The inhibitor of monoaminooxydase isatin and the ligand of B-receptors cholecystokinin-4 play a significant role in the suppression and induction of depressive and anxiety states. We induced the formation of auto-antibodies to these compounds against their conjugates with antigen-carrier by immunization of white rats. The result was long-term (more than 2 months) stimulation of depressive and anxiety behavior after immunization to isatin and, in contrast, the suppression of such behavior after immunization to cholecystokinin. The perspective of immunochemical approach to long-term correction of behavior is discussed.     

The development of a Spanish language version of the Worn Out scale of the General Well-Being Questionnaire (GWBQ)

The paper describes the development of a short Spanish-language version of the General Well-Being Questionnaire (GWBQ; Cox and Gotts, 1987), based on the 12 items of its Worn Out scale. Research has shown the English-version Worn Out scale to be sensitive to aspects of the design and management of work. This study aimed to test its cross-cultural consistency in a Spanish-language workplace context. The data were collected from a sample of 229 workers in Valencia (Spain). Confirmatory Factor Analyses showed the factorial validity, reliability, and concurrent validity of the new Spanish version to be adequate. The sensitivity of the new measure to safety behavior and the reporting of accidents was also assessed and shown to be good. The new questionnaire extends the usefulness of the parent questionnaire to occupational health psychology research in the Spanish language by offering a short assessment tool appropriate for workplace studies.     

A qualitative examination of the relationships that serve a mentoring function for Mexican American older adolescents

This exploratory study was an in-depth examination of Mexican American adolescents' relationships with nonparental adults. Qualitative interviews with 10 Mexican American adolescents revealed 23 nonparental adults who served a mentoring function in their lives. Six of these nonparental adults were also interviewed. Data analyses were conducted using a grounded theory approach so that the relationships were described in participants' words and experiences. The nonparental adults identified by adolescents included siblings, extended family members, older peers, and institutional figures. The support provided took many different forms, from emotional to informational/experiential support, to modeling behavior, for example. Further, adolescents were supported in eight different areas of their lives. Participants also discussed the perceived benefits of these relationships for adolescents. Future research directions and implications for youth programming are discussed.     

The siren's call: terror management and the threat of men's sexual attraction to women

Why do sexually appealing women often attract derogation and aggression? According to terror management theory, women's sexual allure threatens to increase men's awareness of their corporeality and thus mortality. Accordingly, in Study 1 a subliminal mortality prime decreased men's but not women's attractiveness ratings of alluring women. In Study 2, mortality salience (MS) led men to downplay their sexual intent toward a sexy woman. In Study 3, MS decreased men's interest in a seductive but not a wholesome woman. In Study 4, MS decreased men's but not women's attraction to a sexy opposite-sex target. In Study 5, MS and a corporeal lust prime increased men's tolerance of aggression toward women. Discussion focuses on mortality concerns and male sexual ambivalence.     

First graders' literacy and self-regulation gains: The effect of individualizing student instruction

We examined the effect of individualizing student instruction (ISI; N = 445 students, 46 classrooms) on first graders' self-regulation gains compared to a business-as-usual control group. Self-regulation, conceptualized as a constellation of executive skills, was positively associated with academic development. We hypothesized that the ISI intervention's emphasis on teacher planning and organization, classroom management, and the opportunity for students to work independently and in small groups would promote students' self-regulation. We found no main effect of ISI on self-regulation gains. However, for students with weaker initial self-regulation, ISI was associated with greater self-regulation gains compared to peers in control classrooms. The ISI effect on self-regulation was greater when the intervention was more fully implemented.     

Modelling the Moral Dimension of Decisions

In this paper we explore the connections between ethics and decision theory. In particular, we consider the question of whether decision theory carries with it a bias towards consequentialist ethical theories. We argue that there are plausible versions of the other ethical theories that can be accommodated by “standard” decision theory, but there are also variations of these ethical theories that are less easily accommodated. So while “standard” decision theory is not exclusively consequentialist, it is not necessarily ethically neutral. Moreover, even if our decision‐theoretic models get the right answers vis‐à‐vis morally correct action, the question remains as to whether the motivation for the non‐consequentialist theories and the psychological processes of the agents who subscribe to those ethical theories are lost or poorly represented in the resulting models.     

How to have a radically minimal ontology

In this paper I further elucidate and defend a metaontological position that allows you to have a minimal ontology without embracing an error-theory of ordinary talk. On this view ‘there are Fs’ can be strictly and literally true without bringing an ontological commitment to Fs. Instead of a sentence S committing you to the things that must be amongst the values of the variables if it is true, I argue that S commits you to the things that must exist as truthmakers for S if it is true. I rebut some recent objections that have been levelled against this metaontological view.     

Public Storylines in the British Transition from Rail to Road Transport (1896–2000): Discursive Struggles in the Multi-Level Perspective

ABSTRACT

An analysis of the transition from railways to highways as the dominant British transport system during the twentieth century shows that public storylines about competing niche and regime technologies can have a powerful influence on socio-technical transitions. These storylines are developed by supporters and opponents of the competing technologies, with each group attempting to frame their favoured technology positively. The public salience of these storylines can be evaluated by assessing how highly they score on four elements of frame resonance: empirical fit, experiential commensurability, actor credibility, and macro-cultural resonance. These storylines can be seen at play across the entirety of the transition to a road-based transport system, from the very early history of the automobile through to the turn of the millennium, when public opposition to road transport was becoming increasingly pronounced. This case study uniquely traces discursive conflict over the entire course of a multi-decade transition. While existing literature in the multi-level perspective typically emphasises the disadvantages faced by niche-innovations, this case study shows that powerful storylines, enabled by the right cultural repertoires and possibly negative storylines about existing socio-technical systems, can create powerful political support for a new technology, giving it an advantage against more established incumbents.
