The Simon Effect in Action: Planning and/or On‐Line Control Effects?

Choice reaction tasks are performed faster when stimulus location corresponds to response location (Simon effect). This spatial stimulus–response compatibility effect affects performance at the level of action planning and execution. However, when response selection is completed before movement initiation, the Simon effect arises only at the planning level. The aim of this study was to ascertain whether when a precocious response selection is requested, the Simon effect can be detected on the kinematics characterizing the online control phase of a non‐ballistic movement. Participants were presented with red or green colored squares, which could appear on the right, left, above, or below a central cross. Depending on the square's color, participants had to release one of two buttons (right/left), then reach toward and press a corresponding lateral pad. We found evidence of the Simon effect on both action planning and on‐line control. Moreover, the investigation of response conflict at the level of previous trials (i.e., n?1), a factor that might determine interference at the level of the current response, revealed a conflict adaptation process across trials. Results are discussed in terms of current theories concerned with the Simon effect and the distinction between action planning and control.     

Interference and conflict monitoring in individuals with amnestic mild cognitive impairment: A structural study of the anterior cingulate cortex

Amnestic mild cognitive impairment (aMCI) is a clinical condition characterized by memory impairment in the absence of any other cognitive impairment and is commonly associated with high conversion to Alzheimer's disease. Recent evidence shows that executive functions and selective attention mechanisms could also be impaired in aMCI. In this study, we investigated performance differences (i.e., reaction times [RTs] and accuracy) between a group of aMCI participants and a group of age‐matched healthy individuals on the attentional network task (ANT) focusing on situations with increased interference. In particular, we assessed the relationship between interference and conflict effects and grey matter volumes (GMVs) of the anterior cingulate cortex (ACC)/pre‐supplementary motor area in the entire sample because of its crucial role in conflict monitoring. When compared with controls, aMCI participants were less accurate on the ANT, showing increased interference and conflict effects, but no differences in RTs. In addition, aMCI participants exhibited lower GMV in the ACC than controls. While better accuracy for interference and conflict effects was associated with an increase of GMV in the ACC for both groups, RTs from the interference effect were negatively correlated with GMV of the ACC only in aMCI participants. In other words, lower GMV values of the ACC were paralleled with significantly impaired performance in terms of interference resolution. In conclusion, our study suggests the presence of a selective impairment in interference and conflict monitoring in aMCI, which in turn is associated with decreased GMVs in the ACC.     

Between-task transfer of learning from spatial compatibility to a color stroop task

Responses to a relevant stimulus dimension are faster and more accurate when the stimulus and response spatially correspond compared to when they do not, even though stimulus position is irrelevant (Simon effect). It has been demonstrated that practicing with an incompatible spatial stimulus-response (S-R) mapping before performing a Simon task can eliminate this effect. In the present study we assessed whether a learned spatially incompatible S-R mapping can be transferred to a nonspatial conflict task, hence supporting the view that transfer effects are due to acquisition of a general "respond to the opposite stimulus value" rule. To this aim, we ran two experiments in which participants performed a spatial compatibility task with either a compatible or an incompatible mapping and then transferred, after a 5 min delay, to a color Stroop task. In Experiment 1, responses were executed by pressing one of two keys on the keyboard in both practice and transfer tasks. In Experiment 2, responses were manual in the practice task and vocal in the transfer task. The spatially incompatible practice significantly reduced the color Stroop effect only when responses were manual in both tasks. These results suggest that during practice participants develop a response-selection strategy of emitting the alternative spatial response.     

Are community studies of psychological trauma's impact accurate? A study among Jews and Palestinians

We evaluated the accuracy of posttraumatic stress disorder (PTSD) and major depression (MD) diagnoses using brief assessment instruments conducted by phone. PTSD and MD were assessed by telephone interview in a randomly selected sample of Jewish and Palestinian residents of Jerusalem (N = 150) during a period of marked threat of terrorism and war. We utilized the PTSD Symptom Scale Interview Format (Foa, Riggs, Dancu, & Rothbaum, 1993) and the Patient Health Questionnaire-9 (PHQ-9; Kroenke, Spitzer, & Williams, 2001). We then conducted in-depth, in-person interviews within 2 weeks, assessing PTSD and MD using the Composite International Diagnostic Interview (CIDI; Kessler et al., 2004). The prevalence of PTSD and MD diagnosis ascertained by the 2 assessment modalities was similar. Indices of classification accuracy for the phone interview, using the in-person interview as the standard, ranged from modest to high. Brief phone and in-depth in-person measures of PTSD and MD also correlated similarly with other demographic, stress, and coping factors, suggesting convergent validity. Brief phone interviews appear useful for estimating the prevalence of psychological disorders in mass casualty contexts and may have a critical role in both epidemiologic work and guiding public health interventions.     

Integrating work and basic values into the Spherical Model of Interests

Two prominent models of values, one in work and the other in life, were examined as they each related to the dimensions underlying the Spherical Model of Interests (Tracey & Rounds, 1996) as measured by the Personal Globe Inventory (PGI; Tracey, 2002). The technique of external property vector fitting was utilized to plot the value constructs onto two- and three-dimensional interest structures in a sample of 206 college students. Results, when compared across both theoretical and empirical definitions of interest space, indicated that all work values and fewer basic values related to two dimensions, but that only the work value of Achievement and the life value of Power related to the Prestige dimension. Implications for research and for assessment that involves integrating the results of values and interest inventories are discussed.     

An Axiomatic Theory of Law

This paper presents in outline Luigi Ferrajoli’s axiomatic and general theory of law, as developed in his lifelong work Principia Iuris. The first section focuses on the three main aspects of the theory: the methodological, the theoretical and the pragmatic, which respectively represent the theory’s syntax, semantics and its pragmatics. Ferrajoli identifies three deontic gaps of norms: firstly, the one between their validity and efficacy; secondly, the one between their justice and validity; and finally, and most importantly, the one between validity and existence (i.e. normative force). The presence of such gaps is, according to Ferrajoli, the extraordinary innovation that entrenched constitutions have brought into modern legal systems, by establishing norms that are superior to statutes and case law. In this sense, all normative phenomena (except for the constitution itself) can be conceived both as norms and as facts. In the second section the role of juridical science is briefly discussed.     

Degrees of belief in god: a measure of belief for use in cross culture

Belief scales with good psychometric properties are relatively rare. Several scales that claim to measure levels of belief use behavioural indicators that do not necessarily reflect belief, and others refer to specific religions and do not consider ethnic factors or cultural differences. This paper introduces a 6-item multicultural belief scale (the Degrees of Belief in God Scale), based on the results of previous exploratory factor analyses. 2124 Italian, Portuguese, Spanish, Swiss, Turkish and ex-Yugoslavian subjects including Atheists, Catholics, Eastern Orthodox, Moslems and Protestants contributed to the development of the new instrument. Principal component analysis (PCA) followed by varimax-standardized rotation was used to identify (first order) dimensions of belief. In order to identify the shared or common variance in all groups defined by religion and culture of origin a hierarchical analysis of oblique factors was computed for each group. The paper also reports test–retest reliability as well as face, criterion and construct validity data. The resulting Degrees of Belief in God Scale has exceptional psychometric properties and the measurements are equivalent across the sampled cultures and religions.     

Intergroup conflict, out-group derogation, and self-directed negative affect among Italian South Tyroleans

In South Tyrol, a multiethnic Italian province, the authors examined the self-directed negative affect that members of an Italian group experienced after they evaluated members of the German and Albanian groups. The authors examined the affect as a function of out-group derogation. The authors argued that to the extent that out-group derogation may run counter to norms toward intergroup fairness, such normative nonconformity will elicit negative affect directed at the self as a function of perceived intergroup conflict. The findings support the authors' line of reasoning: among Italian South Tyroleans, those who expressed greater out-group derogation were led to experience stronger negative self-directed affect when they rated a low-conflict out-group, but not when they rated a high-conflict out-group, compared to participants whose out-group derogation was less.     

An investigation of the psychological effects of the September 11, 2001, attacks on New York City: developing and implementing research in the acute postdisaster period

The September 11, 2001, attack on New York City was the largest human-made disaster in United States history. In the first few days after the attack, it became clear that the scope of the attacks (including loss of life, property damage, and financial strain) was unprecedented and that the attacks could result in substantial psychological sequelae in the city population. Researchers at the Center for Urban Epidemiologic Studies at the New York Academy of Medicine designed and implemented an assessment of the mental health of New Yorkers 5-8 weeks after the attacks. To implement this research in the immediate postdisaster period, researchers at the center had to develop, in a compressed time interval, new academic collaborations, links with potential funders, and unique safeguards for study respondents who may have been suffering from acute psychological distress. Results of the assessment contributed to a New York state mental health needs assessment that secured Federal Emergency Management Agency funding for mental health programs in New York City. This experience suggests that mechanisms should be in place for rapid implementation of mental health assessments after disasters.     

Kurt Wolff’s Interpretation of Mannheim’s Late Political Writings

This article deals with Kurt Wolff’s interpretation of Karl Mannheim, with reference to his writings on social planning. Wolff’s interpretation is presented and discussed in the context provided by other interpreters of Mannheim. They have, generally speaking, given scant attention to the late works by Mannheim, and rather focused on Ideology and Utopia, Mannheim’s most celebrated work. Interpreters who have considered these writings on planning have been mostly or entirely critical of them, objecting to their vagueness and inadequacy as a project of social reform, and the unsatisfactory conceptualization of the élites. These objections have been raised by several interpreters of different ideological persuasions, from the Marxist thinkers Adorno and Lukacs to the conservative T.S. Eliot. Wolff’s interpretation stands out in that it pays less attention to the social and political contents of Mannheim’s reform project, but brings into light its psychological background; namely, the deep anguish Mannheim experienced because of the widespread tendencies to the formation of a mass society, prone to the forces of irrationalism and authoritarianism. A perusal of Mannheim’s works on planning bears out Wolff’s interpretation.
