Optimal correction for guessing in multiple-choice tests

Subjects’ decisions in multiple-choice tests are an interesting domain for the analysis of decision making under uncertainty. When the test is graded using a rule that penalizes wrong answers, each item can be viewed as a lottery where a rational examinee would choose whether to omit (sure reward) or answer (take the lottery) depending on risk aversion and level of knowledge. We formalize students as heterogeneous decision makers with different risk attitudes and levels of knowledge. Building on IRT, we compute the optimal penalty given students’ optimal behavior and the trade-off between bias and measurement error. Although MCQ examinations are frequently used, there is no consensus as to whether a penalty for wrong answers should be used or not. For example, examinations for medical licensing in some countries include MCQ sections with penalty while in others there is no penalty for wrong answers. We contribute to this discussion with a formal analysis of the effects of penalties; our simulations indicate that the optimal penalty is relatively high for perfectly rational students but also when they are not fully rational: even though penalty discriminates against risk averse students, this effect is small compared with the measurement error that it prevents.     

Psychological factors associated with poor hypertension control: differences in personality and stress between patients with controlled and uncontrolled hypertension

Only one-third of patients with hypertension under pharmacological treatment achieve the recommended blood pressure goals. Psychological factors could partially account for poor hypertension control through the existence of personality traits related to treatment compliance (e.g., self-discipline, deliberation, impulsiveness), and the fact that stress and some personality traits (e.g., anxiety, depression, anger expression, Type A) are involved in the etiology of some hypertension cases. This study was aimed at examining the differences in personality and stress between patients taking antihypertensive medications with controlled and uncontrolled hypertension. Results revealed that after controlling sex, age, and traditional variables associated with poor hypertension control, the uncontrolled hypertension group showed higher scores on impulsiveness, depression, anger expression-out, and stress, with differences ranging between medium and large (Hedges' g effect size = 0.77 to 1.08). These results support the hypothesized relationship between psychological factors and poor hypertension control.     

Grandparent-grandchild relationships from the children's perspective: shared activities and socialization styles

The objective of this study is to describe the relationships between grandchildren and their favourite grandparents, by studying the socialization styles used by latter and the shared activities undertaken. The participants were 360 children between 10 and 12 years old, who completed the grandparent-grandchild relationship questionnaire of Rico, Serra and Viguer (2001) and the socialization questionnaire of Rey and Ruiz (1990). The results demonstrate the importance of gender and family line in the selection of the favourite grandparent, differences being shown in the types of shared activities and in socialization styles. It is concluded that in the majority of cases the profile of the favourite grandparent is the maternal grandmother, retired or a house wife, aged between 60-70, who lives in the same city as his/her grandchild, and who has contact with them several times a week. Furthermore, favourite grandparents get more involved with granddaughters than with grandsons, both in support and care activities and in cultural-recreational activities, and they primarily employ a democratic style. However, there are differences depending on the gender of the grandchild, with democratic principles being used more with girls and authoritarian ones with boys.     

On the Measurement of Implicative Dilemmas

The implicative dilemma (ID) is gradually receiving attention of clinical psychologists and researchers. Although research on its clinical relevance is promising, there are still some issues regarding its measurement that need further consideration. This article explores the adequacy of the different thresholds used to determine construct association, the efficacy of the different indices commonly used to measure IDs, and a verification of the ID not being a mere subproduct of the self-ideal distance. It also introduces a new index. Finally, guidelines are provided for practitioners on how to interpret the indices' numerical results in relation to major depression.     

The Syzygy,Reformulation and New Perspectives: Dreams,Anima-Animus and Gender1

The main objective of this qualitative and quantitative research paper is to explore the occurrences and relations of the anima, animus and androgynous in dreams, with particular emphasis on the consideration of the androgynous in the human psyche. The sample consists of 9 series of dreams (141 dreams in total), from 9 dreamers, 7 women (female sex/gender) and 2 men (male sex/gender), aged 25–57, heterosexual, undergoing Jungian psychotherapy, and presenting couple-related themes. Statistical results and qualitative analysis offer new input for the re-vision of the classical anima-animus model, and the addition of in-depth explorations into the androgynous, paving the way for a new model of psychopathology and psychotherapeutic clinical work, in transition.     

A Golden Lever for Politics: Feminist Emotion and Women's Agency

Pervasive feminism is a component located in emotionality—feminist emotion—and contains women's primary agency. Because affect and emotions are elusive, an interpretive conceptual tool is necessary and is key to making use of their potential for feminist politics aimed at women's empowerment and well‐being and to build gender equality. This essay builds on contemporary feminist theory and affect theory and draws from multidisciplinary research. It presents a new theoretical framework anchored in hermeneutics and phenomenology to pin down the affective component of women's multifaceted, intersectional emotional experiences of gender. A case study also illustrates how the theoretical premises around the concept of feminist emotion are compatible with and useful for feminist praxis.     

“I love you as both and I love you as neither”: Romantic partners’ affirmations of nonbinary trans individuals

Abstract

Background: Transgender microaffirmations are subtle endorsements of a person’s gender identity through both verbal acknowledgements and behavioral gestures. Microaffirmations positively impact individuals who identify as transgender by acknowledging their gender identity and by communicating a sense of support and validation.

Aims: This study focuses on microaffirmations specifically directed toward nonbinary transgender individuals within romantic relationships.

Methods: Participants included 161 adults who identified as nonbinary: 85 who identified as gender nonconforming and 76 who identified as agender. These participants were either currently in a romantic relationship or had been in a romantic relationship within the past 5 years. Participants completed an online survey and provided examples of the microaffirmations they experienced from their romantic partners.

Results: Responses were analyzed via thematic analysis, resulting in four overarching themes: (1) Identity Validations, acknowledgement and acceptance of nonbinary identity; (2) Identity Endorsements, active endorsements of nonbinary through language or behavior; (3) Active Learning, self-education about nonbinary identities; and (4) Active Defense, interruptions of others’ negative actions directed at nonbinary partners.

Discussion: Discussion of the results focuses on understanding how microaffirmations operate to complicate binary notions of gender/sex and positively influence nonbinary transgender individuals in interpersonal relationships.     

Using neural response properties to draw the distinction between modal and amodal representations

ABSTRACT

Barsalou has recently argued against the strategy of identifying amodal neural representations by using their cross-modal responses (i.e., their responses to stimuli from different modalities). I agree that there are indeed modal structures that satisfy this “cross-modal response” criterion (CM), such as distributed and conjunctive modal representations. However, I argue that we can distinguish between modal and amodal structures by looking into differences in their cross-modal responses. A component of a distributed cell assembly can be considered unimodal because its responses to stimuli from a given modality are stable, whereas its responses to stimuli from any other modality are not (i.e., these are lost within a short time, plausibly as a result of cell assembly dynamics). In turn, conjunctive modal representations, such as superior colliculus cells in charge of sensory integration, are multimodal because they have a stable response to stimuli from different modalities. Finally, some prefrontal cells constitute amodal representations because they exhibit what has been called ‘adaptive coding’. This implies that their responses to stimuli from any given modality can be lost when the context and task conditions are modified. We cannot assign them a modality because they have no stable relation with any input type.

Religion and Anti-Immigration Sentiments in Context: Field Studies in Jerusalem

ABSTRACT

Political and social changes in the past decade have rendered questions about religion and immigration more salient than ever. However, we know very little about the potential impact of religion as it operates in the real world on attitudes toward immigrants. In this investigation, we tested whether and how contextual religious cues in the public sphere might affect tolerance toward immigrants. In two studies, we compared the effects of a religious and a secular context (Study 1: religious location; Study 2: religious attire) on attitudes toward Jewish immigrants (i.e., a religious ingroup) and non-Jewish immigrants (i.e., a religious outgroup). Across studies, contextual religious cues predicted ingroup favoritism, as expressed by less social rejection toward religious ingroups and less support for anti-immigration policies affecting religious ingroups. However, contextual religious cues were unrelated to anti-immigration attitudes toward religious outgroups. In Study 2, these patterns were moderated by participants’ religiosity, such that they were found among more (but not fewer) religious participants. These findings extend prior laboratory findings and shed light on how religion influences attitudes toward immigration in rich and complex real environments.
