How do we convert a number into a finger trajectory?

How do we understand two-digit numbers such as 42? Models of multi-digit number comprehension differ widely. Some postulate that the decades and units digits are processed separately and possibly serially. Others hypothesize a holistic process which maps the entire 2-digit string onto a magnitude, represented as a position on a number line. In educated adults, the number line is thought to be linear, but the “number sense” hypothesis proposes that a logarithmic scale underlies our intuitions of number size, and that this compressive representation may still be dormant in the adult brain. We investigated these issues by asking adults to point to the location of two-digit numbers on a number line while their finger location was continuously monitored. Finger trajectories revealed a linear scale, yet with a transient logarithmic effect suggesting the activation of a compressive and holistic quantity representation. Units and decades digits were processed in parallel, without any difference in left-to-right vs. right-to-left readers. The late part of the trajectory was influenced by spatial reference points placed at the left end, middle, and right end of the line. Altogether, finger trajectory analysis provides a precise cognitive decomposition of the sequence of stages used in converting a number to a quantity and then a position.     

Advancing the trait EI content domain: Further evidence for the distinctiveness of interpersonal facets

This investigation sought to assess the congruence of the trait emotional intelligence (EI) sampling domain, reflected in the short form of the Trait Emotional Intelligence Questionnaire (TEIQue; Petrides & Furnham, 2006), with the theoretical content of trait EI—namely, the range of personality traits implicated in emotions. First, associations of the TEIQue factors with Emotion-Oriented Coping (EOC) and Social Coping (SC) were compared. Three of the four TEIQue factors were stronger predictors of EOC than SC; only the Emotionality factor was a stronger predictor of SC. Also, Emotionality did not add to the prediction of EOC in a simultaneous regression with the other factors. Secondly, by means of Structural Equation Modelling, the 30-item composite and a theoretically altered 16-item composite were compared as mediators between the Big Five and the emotion-laden dimension of mental health. Even though all interpersonal items (i.e., those pertaining to Sociability and Emotionality) were omitted for the altered composite, it outperformed the original composite in predicting a latent mental health composite of Stress, Anxiety, and EOC. The results highlight the distinct nature of Emotionality and Sociability facets and have implications for the refinement of the trait EI content domain.     

Factorial validity of the Mental Toughness Questionnaire-48

The purpose of this study was to assess the factorial validity of the Mental Toughness Questionnaire-48 (Clough, Earle, & Sewell, 2002). In total, 8207 participants (male n = 4019, female n = 3922, unspecified = 266) aged between 16 and 68 years (M = 37.00, SD = 12.09) completed the MTQ48. Model fit was assessed using confirmatory factor analysis (CFA) and exploratory structural equation modeling, in addition to the robust maximum likelihood estimator. Overall, our results support the factorial validity of the MTQ48 and indicate that the MTQ48 is a robust psychometric measure of mental toughness. Along with previous data, which supports the internal validity of the MTQ48 in addition to results of this study, it would appear that the MTQ48 is an acceptable method of assessing mental toughness.     

The complex relationship between creativity and affect / La compleja relación entre creatividad y afecto

Abstract

The cognitive components of creativity have been widely studied since the last century. However, the role of non-cognitive elements, particularly affect, has only started to be recognized and researched in the field of psychology during the last decades. This paper offers a critical review of the most relevant contributions to the study of the relationship between creativity and affect, from the preliminary research conducted within the psychoanalytic, humanistic and cognitive frameworks, to the most current lines of research regarding the relationship between creativity and emotional states and traits. We then present three integrative and heuristic models as promising initiatives in the study of such a relationship. Finally, we highlight some theoretical and practical considerations for future studies, such as a greater delimitation of conceptualizations of creativity and affect, and the domain specificity of the relationship between them.     

The Soul Cluster: Reconsideration of a Millennia Old Concept

The article presents a comparative analysis of the theories on conceptions of soul in indigenous and early European traditions. The focal point of the study is the observation that the concept of soul is noticeably complex in aboriginal cultures, and its plural—especially tripartite—nature is the rule rather than the exception. Another observation is that the described pluralism, the number of soul components, and their attributes go through speculative changes as the tradition moves away of tribal origins, which have the shamanic state of consciousness as experiential source of knowledge instead of scholarly theorization. A three-network model of human experience is drawn to support the tripartition cum trilocation concept of soul.     

Cognitive-emotional dysfunction among noisy minds: Predictions from individual differences in reaction time variability

Mental noise can be defined as less reliable information processing. Individuals with high levels of mental noise are thought to be disadvantaged in cognitive, emotional, and behavioural realms. The present five studies (total N=298) investigated such potential disadvantages among normally functioning college undergraduates. Mental noise was operationalised in terms of the reaction time coefficient of variation (RTCV), a measure of RT variability that corrects for average levels of mental speed. Individuals with higher RTCV exhibited less effective cognitive control (Studies 1 and 5), less controlled behaviour (Study 2), and were more prone to negative emotional experiences (Study 3) and depressive symptoms (Study 4). Study 5 extended these results and found that individuals higher (versus lower) in RTCV were more adversely affected by their attentional lapses in daily life. Results converge on the idea that mental noise is an important individual difference dimension with multiple adverse correlates and consequences.     

Father Involvement in Parent Training for Oppositional Child Behavior

Outcome literature (1981 to 1988) on behavioral parent training interventions for nonhandicapped children with oppositional behavior is reviewed to assess the extent and effects of father involvement in parent training. Thirteen studies were found that included some father involvement. Weaknesses of these studies include a failure to observe and measure changed in father-child interactions, a lack of emphasis on the impact of the marital relationship, a lack of attention to similarities in parental child management strategies, and a lack of assessment of paternal characteristics. Further research to assess the effects of including fathers on parent training outcomes can improve the efficiency and effectiveness of these interventions.     

Fragments of a Case of Psychosis: From Institutional Sheltering to Psychoanalytical Experience

This article describes a psychoanalytical experience that took place in an institution for mental health, located in Rio de Janeiro, Brazil. There, an art workshop was created in an attempt to welcome and shelter psychotic patients. This work space later proportioned a ''setting'' for the practice of psychoanalysis with psychotic patients. In the clinical case, herein examined, the author dedicates special attention to the relation that exists between certain psychotic aspects and the process described by Jacques Lacan as: the ''foreclosure of the name of the father''.     

Sick? Or slow? On the origins of intelligence as a psychological object

This paper examines the first moments of the emergence of “psychometrics” as a discipline, using a history of the Binet–Simon test (precursor to the Stanford–Binet) to engage the question of how intelligence became a “psychological object.” To begin to answer this, we used a previously-unexamined set of French texts to highlight the negotiations and collaborations that led Alfred Binet (1857–1911) to identify “mental testing” as a research area worth pursuing. This included a long-standing rivalry with Désiré-Magloire Bourneville (1840–1909), who argued for decades that psychiatrists ought to be the professional arbiters of which children would be removed from the standard curriculum and referred to special education classes in asylums. In contrast, Binet sought to keep children in schools and conceived of a way for psychologists to do this. Supported by the Société libre de l'étude psychologique de l'enfant [Free society for the psychological study of the child], and by a number of collaborators and friends, he thus undertook to create a “metric” scale of intelligence—and the associated testing apparatus—to legitimize the role of psychologists in a to-that-point psychiatric domain: identifying and treating “the abnormal”. The result was a change in the earlier law requiring all healthy French children to attend school, between the ages of 6 and 13, to recognize instead that otherwise normal children sometimes need special help: they are “slow” (arriéré), but not “sick.” This conceptualization of intelligence was then carried forward, through the test's influence on Lewis Terman (1877–1956) and Lightner Witmer (1867–1956), to shape virtually all subsequent thinking about intelligence testing and its role in society.
