Tropes or Universals: How (Not) to Make One's Choice

This article discusses a familiar version of trope theory as opposed to a familiar version of the theory of universals, examining how these two rivals address the problem of “attribute agreement”—a problem that has been at the root of the very reason for developing these theories in the first place. The article shows that there is not much of a difference between the ways these two theories handle the problem, and in a more general way it argues that there is little reason for preferring one theory over the other. It is not interested in this claim only for the sake of the debate between trope theory and the theory of universals. Indeed, the reasons why it claims that it is so difficult to choose one theory over the other can be applied to other cases as well (where they might lead to claims of metaphysical equivalence).     

Choice Blindness and Preference Change: You Will Like This Paper Better If You (Believe You) Chose to Read It!

Choice blindness is the finding that participants both often fail to notice mismatches between their decisions and the outcome of their choice and, in addition, endorse the opposite of their chosen alternative. But do these preference reversals also carry over to future choices and ratings? To investigate this question, we gave participants the task of choosing which of a pair of faces they found most attractive. Unknown to them, we sometimes used a card trick to exchange one face for the other. Both decision theory and common sense strongly suggest that most people would easily notice such a radical change in the outcome of a choice. But that was not the case: no more than a third of the exchanges were detected by the participants. We also included a second round of choices using the same face pairs, and two stages of post‐choice attractiveness ratings of the faces. This way we were able to measure preference strength both as choice consistency and by looking at measures of rating differences between chosen and rejected options. We found that the initially rejected faces were chosen more frequently in the second choice, and the perceived attractiveness of these faces was increased even in uncoupled individual ratings at the end of the experiment. This result is discussed in relation to Chen and Risen's recent criticism of the Free Choice Paradigm, as it shows that choices can affect future preferences.

Interval timing predicts impulsivity in intertemporal choice: combined behavioral and drift-diffusion model evidence

ABSTRACT

This study investigated the relationship between interval timing and impulsivity in intertemporal choice in a healthy population. A duration production task was used to assess interval timing. Choice impulsivity was assessed using a hypothetical money choice task. Results from 134 participants indicated that faster internal clock significantly predicted lower choice impulsivity. A subsequent drift-diffusion model analysis of the behavioural data revealed that in the sub-group of relatively farsighted participants, faster internal clock predicted consideration of more information before making a choice, which in turn was associated with lower choice impulsivity. In the sub-group of relatively impatient participants too, faster internal clock predicted consideration of more information, but which in turn was associated with higher choice impulsivity. It is concluded that among relatively farsighted individuals in a normal population, faster internal clock favours a more deliberate processing of the options at hand, thus eliciting less impulsive choices.     

Justice and peaceful cooperation

Justice is important, but so is peaceful cooperation. In this article, I argue that if one takes seriously the autonomy of individuals and groups and the fact of moral pluralism, a just system of cooperation cannot guarantee peaceful cooperation in a pluralistic world. As a response to this consideration, I develop a contractarian theory that can secure peace in a pluralistic world of autonomous agents, assuming that the agents who exist in this world expect that peaceful cooperation is the most beneficial form of interaction for them in the long run. The theory specifies the restrictions on the behavior of autonomous individual and collective agents that are indispensable for peaceful cooperation in a pluralistic world. In particular, I argue for the need of (i) a globally valid rule of conflict resolution to settle all intra- and inter-group conflicts that cannot be resolved locally, (ii) a world court to apply this rule in cases where local group authorities are inadequate to do so, and to serve as a final court of appeal, and (iii) a world police to enforce the rule.     

The Role of Precues in the Preparation of Motor Responses in Humans

The authors investigated how precues about the location of an upcoming target are used by the sensorimotor system to reduce manual reaction time. In 4 experiments, participants (N = 12 in each experiment) pressed a response key as fast as possible when a precued or a nonprecued visual target appeared. Precues remained effective when a visual mask was interposed between the display of the precue and the target (Experiment 1), which suggests that precues act downstream from visual sensory memory. The precue effect was abolished when precues were presented along with a task requiring attention and a verbal response (Experiment 2) but not when presented with a task that required verbal output but had no attention demands (Experiment 3). Those findings indicate that precues must be processed attentively to become effective. When the attention-demanding task was interposed between precue and target display, the precue effect was still abolished (Experiment 4), which suggests that individuals' attention must remain in the precued area until target appearance.     

The role of friends in career compromise: Same-gender friendship intensifies gender differences in educational choice

We propose a mechanism of how the desire to maintain friendships can intensify gender differences in educational choice. The required conditions for this mechanism would be that (1) adolescent males and females differ in their overall educational preferences, (2) wanting to stay close to friends motivates some adolescents to adjust their educational choice in line with their friends' choices, and (3) adolescents have a higher share of same-gender, than other-gender, friends. Study 1 confirmed that these criteria were met, and Study 2 found an association between friendship priority and gender typed field of study. In conclusion, adjusting educational choices in order to maintain friendships put adolescents at risk of compromising their true career interests, and also becomes an obstacle to a gender balanced labor market.     

An investigation of African-American women's prestige domain interests and choice goals using Social Cognitive Career Theory

Social Cognitive Career Theory (SCCT; Lent, Brown & Hackett, 1994) provides a framework for understanding career development, taking into account background and contextual variables using a social cognitive perspective. Given SCCT's focus on both personal and contextual factors, it has been widely applied to understanding the career development of ethnic minorities and women. This study extends the SCCT framework by testing the SCCT career choice model with variables defined along the prestige dimension, in a sample of 198 African-American college women. Path analysis results supported SCCT propositions for the relations of prestige self-efficacy and prestige outcome expectations with prestige of vocational interests, and of prestige outcome expectations and prestige of vocational interests with prestige of choice goals. The relation of prestige self-efficacy to prestige of choice goals was fully mediated by prestige of vocational interests; the relation between prestige outcome expectations and prestige of choice goals was partially mediated by prestige of vocational interests. Contrary to SCCT, the hypothesized relation of prestige self-efficacy to prestige outcome expectations was non-significant. These findings provide preliminary evidence for the utility of SCCT in explaining the development of prestige-related career interests and choice goals among African-American women.     

Processing inferences at the semantics/pragmatics frontier: Disjunctions and free choice

Linguistic inferences have traditionally been studied and categorized in several categories, such as entailments, implicatures or presuppositions. This typology is mostly based on traditional linguistic means, such as introspective judgments about phrases occurring in different constructions, in different conversational contexts. More recently, the processing properties of these inferences have also been studied (see, e.g., recent work showing that scalar implicatures is a costly phenomenon). Our focus is on free choice permission, a phenomenon by which conjunctive inferences are unexpectedly added to disjunctive sentences. For instance, a sentence such as “Mary is allowed to eat an ice-cream or a cake” is normally understood as granting permission both for eating an ice-cream and for eating a cake. We provide data from four processing studies, which show that, contrary to arguments coming from the theoretical literature, free choice inferences are different from scalar implicatures.
