Olp: An R package for optimal linear partitions of finite sets of points on the plane

Given a set of points on the plane and an assignment of values to them, an optimal linear partition is a division of the set into two subsets which are separated by a straight line and maximally contrast with each other in the values assigned to their points. We present a method for inspecting and rating all linear partitions of a finite set, and a package of three functions in the R language for executing the computations. One function is for finding the optimal linear partitions and corresponding separating lines, another for graphically representing the results, and a third for testing how well the data comply with the linear separability condition. We illustrate the method on possible data from a psychophysical experiment (concerning the size–weight illusion) and compare its performance with that of linear discriminant analysis and multiple logistic regression, adapted to dividing linearly a set of points on the plane.     

Fakability of Implicit and Explicit Measures of the Big Five: Research findings from organizational settings

This study investigates the extent to which response distortion occur when implicit measures of personality traits are used in applied settings. Two groups composed of 58 security guards and 45 semiskilled workers, respectively, completed five Implicit Association Tests (IATs) for assessing the Big Five personality traits as a part of a personnel assessment program. They additionally completed a self‐report measure of the same personality dimensions. Scores on the Big Five IATs and self‐ratings of personality were obtained also by 52 volunteers who responded anonymously for research purposes. Results showed that participants under evaluative testing conditions scored significantly higher than volunteers on explicit measures of agreeableness, conscientiousness, and emotional stability. On the contrary, no significant differences were found in the Big Five IATs. Practical implications of findings and future research directions are discussed.     

Attachment and Relational Psychoanalysis: Bowlby According to Mitchell

In our contribution we would like to highlight that the model formulated by Mitchell in his last book entitled Relationality seems to suggest that he had come to realize that he could not exclude attachment theory entirely from his theoretical framework. Some of the most interesting interpretations of it—post-Bowlbian interpretations—regarded the dynamics of early attachment as a fundamental model of emotional regulation. We think that in Italy there has always been a significantly widespread sensitivity toward developmental and attachment themes also in more strictly psychoanalytic contexts, hence the specific slant of our reading of the most recent developments in relational psychoanalysis.     

Influences of Work-Family Interface on Job and Life Satisfaction

Research investigating the relationship between family and work domains, according to a reductionist approach, has traditionally focused on the negative aspects of the work-family relationship. However, over the past 15 years a number of studies have also focused on the positive aspects of family and work relationships and on the interactions between the work-family interface and outcomes such as job and life satisfaction. These research studies have made it possible to capture different facets of the relationship between family and working life, and to clarify the specific nature of these interactions. In the present study, we tested a model that included positive and negative interactions between work and family as predictors of job and life satisfaction. We also examined the role of some of the potential moderators (work engagement, organizational and family support) of these relationships, using a sample of 427 Italian employees working in public administration. In our analysis, we first tested the factorial structure of the work-family interface measure (Kinnunen et al. Scandinavian Journal of Psychology, 47, 149–162 2006). Factor analysis confirmed a four-factor model: negative work-to-family interface, negative family-to-work interface, positive work-to-family interface, and positive family-to-work interface. Secondly, we analyzed the relationship between the work-family interface, job satisfaction and life satisfaction. Path analysis showed that the factors involved in the work-family interface influenced directly and indirectly life satisfaction, job satisfaction and work engagement. This analysis also showed that work engagement had a direct strong effect on job satisfaction and a direct weaker effect on life satisfaction. This pattern of findings is consistent with a causal sequence in which the work-family interface (WIF) and family-work interface (FIW) can increase or reduce a satisfaction-specific domain. Our results highlight the importance of using a theoretical and empirical model that integrates and focuses on both the positive and negative aspects of the work-family relationship. Moreover, this pattern demonstrates the potential consequences of this influence on employees’ working life and general well-being.     

Framing the EU as Common Project vs. Common Heritage: Effects on Attitudes Towards the EU Deepening and Widening

The present study investigated the effects of framing the European Union (EU) as a common project vs. a common heritage on participants’ attitude towards EU integration (Experiment 1) and EU enlargement (Experiment 2). An additional aim was exploring whether the different frames affected the strength of identification with the EU, and if the framing effect on attitudes was mediated by participants’ identification with the EU and/or by their message evaluation (Experiment 3). Results showed that a common project-based frame was more effective than a common heritage-based frame in promoting positive attitude toward EU integration and enlargement, as well as participants’ identification with the EU, which mediated the framing effect on both attitudes; the mediation of participants’ message evaluation was not significant. The procedure of the last experiment was replicated on a British sample (Experiment 4), showing a similar pattern of results.     

Illness Perception and Well-Being Among Persons with Multiple Sclerosis and Their Caregivers

This study jointly examined illness beliefs held by persons with multiple sclerosis (PwMS) and caregivers in relation to well-being. A group of 68 PwMS and their caregivers completed the Revised Illness Perception Questionnaire, Psychological Well-being Scales, Satisfaction with Life Scale and Positive Affect and Negative Affect Schedule. Findings revealed that PwMS’ well-being was primarily predicted by their own illness beliefs, and that also caregivers’ well-being was primarily predicted by their own beliefs. Across the two groups, well-being was positively associated with their belief that they understood the disease, and inversely associated with their representations of negative emotions. In addition, among PwMS, well-being was inversely associated with the number of symptoms they specifically attributed to their illness, while among caregivers, well-being was positively associated with beliefs that treatment could control the disease. Based on the study findings, psychoeducational and cognitive-behavioral strategies are suggested to promote well-being among PwMS and caregivers.     

Measuring the automatic negative self-schema: New evidence for the construct and criterion validity of the Depression Implicit Association

The construct and criterion validity of the Depression Implicit Association Test (Depression IAT) as a marker of an automatic negative self-schema was investigated. The Depression IAT and other measures were administered to a sample of 116 participants (72 females) aged 37.28 (SD = 15.69) that was composed by 56 patients with an history of suicide ideation (SI) and by 60 university students. Combining students and patients’ sub-samples, results revealed that the Depression IAT was significantly and positively correlated with self-report scales of depression and hopelessness as well as with implicit and explicit measures of death-life identification. On the contrary, it was negatively correlated with life satisfaction, optimism, and self-esteem scales. These results give new evidence for the construct validity of the Depression IAT. Moreover, considering only the patients’ sub-sample, significant correlations between Depression IAT scores and SI in the last year, month, and week, as well as in a follow-up observation two months later, were found. These correlations remain unchanged even when the Death IAT was controlled for, supporting the incremental validity of the Depression IAT. Overall, these results provide new evidence for the construct and criterion validity of the Depression IAT as a marker of an automatic negative self-schema.     

The cognitive foundations of visual consciousness: Why should we favour a processing approach?

How can we investigate the foundations of consciousness? In addressing this question, we will focus on the two main strategies that authors have adopted so far. On the one hand, there is research aimed at characterizing a specific content, which should account for conscious states. We may call this the content approach. On the other hand, one finds the processing approach, which proposes to look for a particular way of processing to account for consciousness. . Our aim, in this paper, is to develop arguments for the latter approach. We focus on a criticism of Jesse Prinz’s AIR theory of consciousness. We have chosen Prinz’s theory because it incorporates features of both the content and processing approaches, and discussing it will therefore allow us to compare the advantages and downsides of both. Our argument will focus in particular on the notion of intermediate-level. We will discuss how Prinz characterizes the intermediate-level according to a content approach, and argue that such a characterization is inadequate. Finally, we will argue in favor of processing approach to the problem of consciousness, which also accounts for the massive interaction of top-down and bottom-up processes in the brain. Even though consciousness remains an unsolved riddle, we claim that this is the best path towards a solution.
