All Giraffes Have Female‐Specific Properties: Influence of Grammatical Gender on Deductive Reasoning About Sex‐Specific Properties in German Speakers

Grammatical gender is independent of biological sex for the majority of animal names (e.g., any giraffe, be it male or female, is grammatically treated as feminine). However, there is apparent semantic motivation for grammatical gender classes, especially in mapping human terms to gender. This research investigated whether this motivation affects deductive inference in native German speakers. We compared German with Japanese speakers (a language without grammatical gender) when making inferences about sex‐specific biological properties. We found that German speakers tended to erroneously draw inferences when the sex in the premise and grammatical gender of the target animal agreed. An over‐generalization of the grammar–semantics mapping was found even when the sex of the target was explicitly indicated. However, these effects occurred only when gender‐marking articles accompanied the nouns. These results suggest that German speakers project sex‐specific biological properties onto gender‐marking articles but not onto conceptual representations of animals per se.     

Consistent Treatment of Variables and Causation Poses a Challenge for Behavioral Research Methods: A Commentary on Nesselroade and Molenaar (2016)

Nesselroade and Molenaar presented the ideographic filter as a proposal for analyzing lawful regularities in behavioral research. The proposal highlights an inconsistency that poses a challenge for behavioral research more generally. One can distinguish a broadly Humean approach from a broadly non-Humean approach as they relate to variables and to causation. Nesselroade and Molenaar rejected a Humean approach to latent variables that characterizes them as nothing more than summaries of their manifest indicators. By contrast, they tacitly accepted a Humean approach to causes characterized as nothing more than summaries of their manifest causal effects. A non-Humean treatment of variables coupled with a Humean treatment of causation creates a theoretical tension within their proposal. For example, one can interpret the same model elements as simultaneously representing both variables and causes. Future refinement of the ideographic filter proposal to address this tension could follow any of a number of strategies.     

Abduction by Philosophers: Reorienting Philosophical Methodology

A reorientation is needed in methodological debate about the role of intuitions in philosophy. Methodological debate has lost sight of the reason why it makes sense to focus on questions about intuitions when thinking about the methods or epistemology of philosophy. The problem is an approach to methodology that focuses almost exclusively on questions about some evidential role that intuitions may or may not play in philosophers’ arguments. A new approach is needed. Approaching methodological questions about the role of intuitions in philosophy with an abductive model of philosophical inquiry in mind will help ensure the debate doesn't lose sight of what motivates the debate.     

3～5岁幼儿在视野阻隔任务中的长度传递性推理

设计视野阻隔任务,控制了短时记忆和直接比较的两难问题,考察3～5岁幼儿长度传递性推理能力的发展趋势和传递性推理这一认知过程的发展序列。以2(间隔长度)×2(摆放方式)×4(年龄)的三因素混合设计,研究了240名幼儿,结果表明:(1)3～4岁是长度传递性推理能力的快速发展期,4岁以后的幼儿大部分具备了这一能力,发展速度趋于平缓;(2)任务类型影响推理成绩;(3)基于传递关系的推理依据与推理总成绩显著正相关。研究认为:年仅4岁幼儿具备传递性推理能力蕴含教育价值;传递性推理的认知过程经历了四个可辨别的发展序列,依次主要发生在36～42个月、43～48个月、49～54个月和55～60个月的幼儿当中。     

Seeking Confirmation Is Rational for Deterministic Hypotheses

The tendency to test outcomes that are predicted by our current theory (the confirmation bias) is one of the best‐known biases of human decision making. We prove that the confirmation bias is an optimal strategy for testing hypotheses when those hypotheses are deterministic, each making a single prediction about the next event in a sequence. Our proof applies for two normative standards commonly used for evaluating hypothesis testing: maximizing expected information gain and maximizing the probability of falsifying the current hypothesis. This analysis rests on two assumptions: (a) that people predict the next event in a sequence in a way that is consistent with Bayesian inference; and (b) when testing hypotheses, people test the hypothesis to which they assign highest posterior probability. We present four behavioral experiments that support these assumptions, showing that a simple Bayesian model can capture people's predictions about numerical sequences (Experiments 1 and 2), and that we can alter the hypotheses that people choose to test by manipulating the prior probability of those hypotheses (Experiments 3 and 4).     

The similarity heuristic

Decision makers often make snap judgments using fast‐and‐frugal decision rules called cognitive heuristics. Research into cognitive heuristics has been divided into two camps. One camp has emphasized the limitations and biases produced by the heuristics; another has focused on the accuracy of heuristics and their ecological validity. In this paper we investigate a heuristic proposed by the first camp, using the methods of the second. We investigate a subset of the representativeness heuristic we call the “similarity” heuristic, whereby decision makers who use it judge the likelihood that an instance is a member of one category rather than another by the degree to which it is similar to others in that category. We provide a mathematical model of the heuristic and test it experimentally in a trinomial environment. In this environment, the similarity heuristic turns out to be a reliable and accurate choice rule and both choice and response time data suggest it is also how choices are made. We conclude with a theoretical discussion of how our work fits in the broader “fast‐and‐frugal” heuristics program, and of the boundary conditions for the similarity heuristic.

A/B型人格对时间性前瞻记忆的影响

通过对比A/B两种人格者在执行即无社会关系特征又无个人重要性的时间性前瞻记忆任务时的时间性前瞻记忆成绩和在执行时间性前瞻记忆过程中的时间监控模式,发现A/B型人格的背景任务成绩和TBPM任务成绩都没有显著差异,而时间监视模式有显著差异。说明A型人格被试能更高效的利用认知资源,以更高效和更策略的时间监控模式完成TBPM任务。也说明TBPM是一类与时间监控能力密切相关的前瞻记忆类型。     

The automatic and co-occurring activation of multiple social inferences

People make a variety of automatic inferences when observing others' actions. These include inferences about stable dispositions as well as transitory goal states and social situations. However, models of social inference have rarely considered whether different types of automatic inferences can co-occur. We present three experiments in which participants were incidentally exposed to texts depicting behaviors that afforded inferences about actors' traits and the social situations these actors were experiencing. Results from lexical decision and probe-recognition tasks revealed heightened activation of both trait and situational inferences; furthermore, this co-occurring activation was spontaneous, unconscious, and independent of processing resources or specific impression-formation goals. A fourth experiment extended these findings by showing that when participants were asked to make deliberate attributional judgments of the same set of behaviors, typical goal-directed biases reflecting the selection of either trait or situational interpretations emerged. Implications for social inference processes are discussed.
