Greater response cardinality indirectly reduces confidence

Koriat's Self-Consistency Model of subjective confidence proposes that the consistency and accessibility with which a response is retrieved are cues to confidence in the accuracy of that response. The Self-Consistency Model, however, has only been assessed using two-alternative forced-choice questions. Consideration of open-ended questions suggested that response cardinality—the number of unique response options that might come to mind—should directly reduce response consistency, and thus indirectly reduce confidence. Australian undergraduate students (N?=?389) completed a 20-item open-ended general-knowledge test with confidence ratings attached to each answer. Replicating previous Self-Consistency Model findings, but in an open-ended format for the first time, consistency and accessibility were independent positive predictors of confidence, though the prediction of accessibility did not reach statistical significance. Extending the model, the number of unique responses given by participants, a measure of response cardinality, was found to be a strong negative predictor of consistency and indirect negative predictor of confidence. Implications of the results therefore include the use of simple strategies such as prompting or providing varying numbers of response options as potentially effective for manipulating cardinality and thus confidence.     

Validation of the Empathy Quotient in Mainland China

This research aimed to validate a simplified Chinese version of the Empathy Quotient (EQ; 60 items) for use with Mainland Chinese people. The original English version of the EQ was translated into simplified Chinese. Through an online survey, 588 Mainland Chinese participants completed the EQ and 3 other questionnaires: the Interpersonal Reactivity Index (IRI), the Autism-Spectrum Quotient (AQ), and the 20-item Toronto Alexithymia Scale (TAS–20). Thirty-five participants completed retesting of the EQ 3 to 4 weeks later. Sex differences on the EQ scores and psychometric properties of the EQ items were examined. Confirmatory factor analysis suggested that an EQ 15-item structural model fitted the data quite well. Self-report empathy, as assessed by the current simplified Chinese version of the EQ, appeared to relate to participants' autistic and alexithymic traits but not sex.     

Truthlikeness and the Lottery Paradox via the Preface Paradox

In a 2017 AJP paper, Cevolani and Schurz (C&S) propose a novel solution to the Preface Paradox that appeals to the notion of expected truthlikeness. This discussion note extends and analyses their approach by applying it to the related Lottery Paradox.     

Valuing the future: a MADA example involving nuclear waste storage

Intertemporal decision making involves decisions that have consequences that span several periods of time and often extend far into the future. The purpose of this paper is to discuss and highlight the differences associated with different evaluation methods designed to cope with the long-term impacts of a decision including discounting. The concepts and ideas are illustrated in the context of a decision about a nuclear waste facility. We show how applying different discounting methodologies can greatly affect the decision made, especially over long time periods. © 1998 John Wiley & Sons, Ltd.     

From landsmanshaften to vinkln: Mediating community among Yiddish speakers in America

Vinkln (“corners”) in America have spread since the 1970s as an organizational strategy by Yiddish-speaking, non-pietistic, East European Jewish immigrants, many of whom have a Holocaust experience. The vinkln provide a privatized, immersive experience for Yiddish language and culture as a way to offer community identity to Yiddish speakers within the wider Jewish community. They arose out of landsmanschaften, or “hometown associations,” in the early twentieth century, but the vinkln function to ritually reproduce culture rather than offer mutual aid based on old-country affiliation. Although secularized, the organized social structure and performed communication of the vinkln invoke rituals and roles of Jewish religious services from traditional community experience. They displace old-country affiliations with pronounced loyalties to Israel and America, although the location of Yiddish in performance is often centered in Poland. The vinkln mediate community by suggesting cultural reproduction even as the bonds of language and society among Yiddish speakers are weakening. Its symbols and associations are restricted to an elderly age cohort, and therefore not likely to perpetuate the very culture that its organizers purport to preserve. It is differentiated from other structures of Yiddish conservation and appreciation such as Internet networks and community center conversation groups. This revised version was published online in June 2006 with corrections to the Cover Date.     

Normativity à la Mode

This paper sets out to raise questions about the metaphor of the spaceof reasons. It argues that a proper appreciation of Wittgensteinundermines the metaphysical or dualistic way of taking the metaphor thatis supposed to prevent the naturalization of reason.     

Collaborative Discovery in a Scientific Domain

This study compares Pairs of subjects with Single subjects in a task of discovering scientific laws with the aid of experiments. Subjects solved a molecular genetics task in a computer micro-world (Dunbar, 1993). Pairs were more successful in discovery than Singles and participated more actively in explanatory activities (i.e., entertaining hypotheses and considering alternative ideas and justifications). Explanatory activities were effective for discovery only when the subjects also conducted crucial experiments. Explanatory activities were facilitated when paired subjects made requests of each other for explanation and focused on them. The study extends from individual to collaborative discovery activities the importance to the discovery process of setting goals to find hypotheses and evidence (Dunbar, 1993) and to construct explanations of phenomena and processes encountered in examples (Chi, Bassok, Lewis, & Glaser, 1989).     

Parent-infant interaction: a growth model approach

The aim of this study is to compare the interaction of fathers and mothers with their 10–12 months old infants (n = 97; parental sensitivity and mood, and infant mood) during five structured contiguous play segments, and to examine the utility of individual growth modeling. Conventional comparison of means across play-segments showed that parents were equally responsive, but mothers were happier than fathers, and infants were equally happy during interaction with both parents. Sensitivity and mood were more strongly related for mothers than for fathers. Uni- and multivariate growth models revealed fine-grained patterns not seen in conventional analysis: (a) parental and infant mood decreased across play more for mothers than for fathers, (b) parental sensitivity in one play-segment predicted parental mood and infant mood in the next segment, (c) change in infants’ mood was related to change in sensitivity in mothers, and to change in mood in fathers, and (d) mothers’ sensitive interaction with the infant was predicted by family socio-demographic background.
