The effects of prior expectations and outcome knowledge on polygraph examiners' decisions

The present study deals with the question of whether judgments made by experts working in familiar contexts are affected by prior expectations and beliefs. Two experiments in which prior expectations were manipulated were designed to determine whether and to what extent polygraph examiners are affected by their prior expectations when analyzing and interpreting polygraph charts. Prior expectations affected the examiners' judgments when the polygraph charts did not include clear indications of guilt or innocence, but when the objective physiological evidence included strong indications which clearly contradicted the examiner's expectations, judgments were not affected by these expectations. Theoretical and practical implications of these results are discussed.     

Multiple-probe technique: a variation on the multiple baseline

Multiple-baseline and probe procedures are combined into a “multiple-probe” technique. The technique is designed to provide a thorough analysis of the relationship between an independent variable and the acquisition of a successive-approximation or chain sequence. It provides answers to the following questions: (1) What is the initial level of performance on each step in the training sequence? (2) What happens if sequential opportunities to perform each next step in the sequence are provided before training on that step? (3) What happens when training is applied? (4) What happens to the performance of remaining steps in the sequence as criterion is reached in the course of training each prior step? The technique features: (1) one initial probe of each step in the training sequence, (2) an additional probe of every step after criterion is reached on any training step, and (3) a series of “true” baseline sessions conducted just before the introduction of the independent variable to each training step. Intermittent probes also provide an alternative to continuous baseline measurement, when such measurement during extended multiple baselines (1) may prove reactive, (2) is impractical, and/or (3) a strong a priori assumption of stability can be made.     

A method for combining occurrence and nonoccurrence interobserver agreement scores

Various statistics have been proposed as standard methods for calculating and reporting interobserver agreement scores. The advantages and disadvantages of each have been discussed in this journal recently but without resolution. A formula is presented that combines separate measures of occurrence and nonoccurrence percentages of agreement, with weight assigned to each measure, varying according to the observed rate of behavior. This formula, which is a modification of a formula proposed by Clement (1976), appears to reduce distortions due to "chance" agreement encountered with very high or low observed rates of behavior while maintaining the mathematical and conceptual simplicity of the conventional method for calculating occurrence and nonoccurrence agreement.     

Defense mechanisms in alcoholics attending outpatient treatment. Results from the MCT-test (Meta-Contrast Technique)

Defensive strategies were studied in 72 alcoholics participating in outpatient treatment by using, before the treatment started, the Meta-Contrast Technique, MCT, a percept-genetic method. Alcoholics had less often adaptive strategies than controls. A lack of adaptive defense strategies was related to a more impaired psychic status, more psychological benefits from drinking, and more psychiatric symptoms but not to severity of alcoholism or results of psychometric tests (intellectual level, field-dependence, spatial performance). It does not seem inconceivable that the MCT could be used as a diagnostic tool in treatment planning.     

THE LIMITS OF PRAGMATISM AND THE LIMITS OF REALISM

Abstract. I argue here for a limited version of pragmatism—called conceptual pragmatism—that recognizes that conceptual systems are to be evaluated according to their usefulness for helping us get around in the world. Once a conceptual system is in place, however, the truth of sentences is a matter of both empirical tit and coherence with the rest of our knowledge. The error of critical realists is to fail to take into account the limited conceptual relativity that is to be expected on the basis of conceptual pragmatism. The conceptual realist thesis applies equally in science and theology.     

The relevance of Habermas' communicative turn

This paper points out the way in which educational and communicative action (Habermas) are to be related. It is shown that earlier attempts to put Habermas ideas to use have led to a dead end because they do not realize clearly that the new basic notion introduced by Habermas, namely communicative action, is the expression of a communicative turn. It is argued that Habermas' concept expresses a radical new attempt to grasp the intersubjective character of social action. Next implications of this communicative turn for the concept of education as a social praxis are indicated. Education can be conceived of as a praxis responding to the vulnerability of a communicative self.     

跨期决策中的维度差异偏好：眼动证据

在跨期决策研究领域,虽然基于维度的跨期模型得到了一些源自结果检验和过程检验的证据支持,但此类模型所假设的维度间差异比较的心理过程尚缺乏直接的过程证据。本研究通过两个眼动实验,系统考察了相关眼动指标对维度差异偏好的预测效应。结果发现,根据基于维度的权衡模型可有效拟合出个体在跨期决策中的维度差异偏好,并且反应时、眼跳注视熵和静态注视熵等指标均与维度差异偏好负相关,而基于维度的注意分配与维度差异判断正相关。这些研究发现支持了本研究所提出的跨期眼动模型的相关假设,证实了维度差异偏好与跨期决策的认知加工过程之间的联系,为基于维度的跨期模型提供了更直接的过程证据,并为今后跨期决策的眼动模型发展指明了新方向。     

“Keep them out to save our inside:” discourses on immigration by the Spanish far right

Vox is a far-right, Spanish political party that has steadily grown to become the third main party in the national congress. Immigration is a major presence in Vox's political agenda. Through Critical Discourse Analysis, we analyze the party's public speeches and Twitter communications on immigration in the last 3 years, from the beginning of the COVID-19 pandemic in 2020 to the Ukraine-Russia war in 2022. These contexts have provided a fertile ground for Vox's concerns with the protection of national borders, the criminalization of African and irregular immigrants, and the Spanish Government's ineffectiveness to protect the Spaniards' homes. Vox's main discursive strategies entail constructions of migrants and migration based on dichotomous binaries, culture clash, exclusionary discourses of domopolitics, and fears of imminent social and cultural changes. These constructions are based on the unproblematized belief on essential and unchangeable values that forge the identity of the homeland, which is implicitly threatened by immigrants. Against the migratory invasion, Vox constitutes itself as the ethical protector of the Spanish society and nation, “out of care for the insiders and not out of hatred for outsiders.”     

Reply to Psarros: Popper and Chemistry

In this article I reply to criticism of my published work by N. Psarros (Journal for the General Philosophy of Science 28: 297–305,1997). I show that I had already answered the first criticism in my published work and not overlooked his supposed refutation. However I offer a plausible argument which he could have used to strengthen his claim. Psarros cites my work on Hopkins in his opening paragraph, but then makes no further reference to it in the text. I indicated to Psarros verbally at Ilkley 1994 (and reiterate the message here) that Hopkins' work on Vitamins is the exemplar of a Popperian historical episode and must require addressing by the opponents of critical rationalism.
