Approaches to Jewish Studies: Teaching a Methods Class

Abstract. Like religious studies, Jewish studies is an academic exploration of literature, ritual, history, philosophy, and experience across disciplinary boundaries. As with all area studies, Jewish studies balances itself – often precariously – as a bridge across that range of methodological options. The breadth of theories employed by each has complicated the teaching of an upper level seminar in Jewish studies. Conceived as a cross between a parade of scholars course and a senior capstone experience, the class employed the broad thematic principle of “identity.” In doing so, it exposed the biases of the students, the subject, and the instructor.

The hippocampus: hub of brain network communication for memory

A complex brain network, centered on the hippocampus, supports episodic memories throughout their lifetimes. Classically, upon memory encoding during active behavior, hippocampal activity is dominated by theta oscillations (6-10Hz). During inactivity, hippocampal neurons burst synchronously, constituting sharp waves, which can propagate to other structures, theoretically supporting memory consolidation. This 'two-stage' model has been updated by new data from high-density electrophysiological recordings in animals that shed light on how information is encoded and exchanged between hippocampus, neocortex and subcortical structures such as the striatum. Cell assemblies (tightly related groups of cells) discharge together and synchronize across brain structures orchestrated by theta, sharp waves and slow oscillations, to encode information. This evolving dynamical schema is key to extending our understanding of memory processes.     

A tale of two negatives: differential memory modulation by threat-related facial expressions

Facial expressions serve as cues that encourage viewers to learn about their immediate environment. In studies assessing the influence of emotional cues on behavior, fearful and angry faces are often combined into one category, such as "threat-related," because they share similar emotional valence and arousal properties. However, these expressions convey different information to the viewer. Fearful faces indicate the increased probability of a threat, whereas angry expressions embody a certain and direct threat. This conceptualization predicts that a fearful face should facilitate processing of the environment to gather information to disambiguate the threat. Here, we tested whether fearful faces facilitated processing of neutral information presented in close temporal proximity to the faces. In Experiment 1, we demonstrated that, compared with neutral faces, fearful faces enhanced memory for neutral words presented in the experimental context, whereas angry faces did not. In Experiment 2, we directly compared the effects of fearful and angry faces on subsequent memory for emotional faces versus neutral words. We replicated the findings of Experiment 1 and extended them by showing that participants remembered more faces from the angry face condition relative to the fear condition, consistent with the notion that anger differs from fear in that it directs attention toward the angry individual. Because these effects cannot be attributed to differences in arousal or valence processing, we suggest they are best understood in terms of differences in the predictive information conveyed by fearful and angry facial expressions.     

Engineering Eden: Does Earthly Pursuit of Eternal Life Threaten the Future of Religion?

The eternal life promised by many religions is mirrored by the drastically longer lifespans proposed by radical life extension (RLE) and transhumanism (H+). RLE and H+ represent extreme contingents of longevity research among the broader scientific initiatives to extend the length and quality of human life. In striving toward literal immortality, these movements offer an “alternative” to the spiritual eternity that functions as a religious solution to fear of death and loss. In this article, we probe the question of whether a radically extended—even eternal—life through advancements in biotechnology could replace religion as a means of managing this terror of death.     

Not as gloomy as we thought: reassessing how the public understands probability of precipitation forecasts

Prior research on probability of precipitation (PoP) forecasts showed that many people wrongfully believe that PoP forecasts are derived from a percentage of time, a percentage of a region or the strength of agreement among forecasters. We posit that the wording of interpretation selection tasks matters, because different response options are associated with different metacognitive feelings. We hypothesised that the incorrect PoP interpretations are more often chosen by participants because they are more fluent than the correct PoP interpretation. We assessed the role of fluency in correctness perception (Study 1) and reassessed PoP interpretations with a more fluent correct interpretation (Study 2). Fluency perception was positively related with perception of correctness. Furthermore, participants selected the correct fluent interpretation more often than the correct disfluent one. We have drawn a more optimistic picture of people’s PoP forecasts understanding than that shown before and have discussed the methodological and applied implications.     

Gender bias in caregiving professions: The role of perceived warmth

One hypothesized reason for why a disproportionately low number of men enter caregiving fields is how such men are perceived. In two studies, drawing upon the Stereotype Content Model and the lack‐of‐fit model, we tested whether men would encounter more social (e.g., likeability bias) and economic (e.g., hiring or job opportunity bias) penalties than women in caregiving professions due to perceptions that men are less warm than women. In all three studies, we created job or employment materials in which the gender of the candidate or employee was manipulated. In Study 1, a female preschool teacher received higher warmth ratings than a male preschool teacher, which in turn predicted preference for the female teacher over the male teacher. In Study 2, a female social worker was rated more highly in warmth and job hireability than a male social worker; warmth also mediated the relationships between gender and both likeability and job hireability. In Study 3, a male preschool teacher was rated lower in warmth, likeability, job hireability, and job suitability than both a female preschool teacher and a preschool teacher with an unspecified gender. There were no differences between perceived competence of men and women in caregiving positions when competence was assessed. Implications for the factors that predict adverse reactions to and penalties against men in caregiving occupations, as well as interventions to combat the potential negative effects of such penalties on men's interest in caregiving careers, are discussed.     

Skin-to-Skin contact (Kangaroo care) promotes self-regulation in premature infants: sleep-wake cyclicity, arousal modulation, and sustained exploration

The effect of mother-infant skin-to-skin contact (kangaroo care, or KC) on self-regulatory processes of premature infants was studied. Seventy-three infants who received KC were compared with 73 infants matched for birth weight, gestational age, medical risk, and family demographics. State organization was measured in 10-s epochs over 4 hr before KC and again at term. No differences between KC infants and controls were found before KC. At term, KC infants showed more mature state distribution and more organized sleep-wake cyclicity. At 3 months, KC infants had higher thresholds to negative emotionality and more efficient arousal modulation while attending to increasingly complex stimuli. At 6 months, longer duration of and shorter latencies to mother-infant shared attention and infant sustained exploration in a toy session were found for KC infants. The results underscore the importance of maternal body contact for infants' physiological, emotional, and cognitive regulatory capacities.     

Mental pain: a multidimensional operationalization and definition

An operationalization of mental pain is presented in three studies. The first study describes the operationalization of mental pain and the factor structure of the items produced by a content analysis of self-reports yielding a scale with nine factors: the experience of irreversibility, loss of control, narcissistic wounds, emotional flooding, freezing, estrangement, confusion, social distancing, and emptiness. Study 2 tested the relationship between mental pain and depression and anxiety in a normal population. Study 3 focused on the relationship between mental pain and coping. Mental pain is conceptualized as a perception of negative changes in the self and its functions that are accompanied by negative feelings. It is suggested that it can be meaningfully applied to the study of different mental states, life conditions, and transitions in life.     

Cognitive Reflection Predicts Real‐Life Decision Outcomes,but Not Over and Above Personality and Decision‐Making Styles

The Cognitive Reflection Test (CRT), designed to assess the ability to inhibit intuition to process a problem analytically, predicts people's performance in many normative judgement and decision‐making tasks (e.g., Bayesian reasoning, conjunction fallacy and ratio bias). However, how the CRT predicts normative decision‐making performance is unclear, and little is known about the extent to which the CRT predicts real‐life decision outcomes. We investigate the role of the CRT in predicting real‐life decision outcomes and examine whether the CRT predicts real‐life decision outcomes after controlling for two related individual differences: the Big Five personality traits and decision‐making styles. Our results show that greater CRT scores predict positive real‐life decision outcomes measured by the Decision Outcome Inventory. However, the effect size was small, and the relationship became non‐significant after statistically controlling for personality and decision‐making styles. We discuss the limited predictive role of cognitive reflection in real‐life decision‐making outcomes, along with the roles of personality and decision‐making styles.
