International Collaboration as Construction of Knowledge and its Constraints

In this paper I draw on Piaget and Habermas to underline the importance of the theoretical distinction between social relations of constraint and social relations of cooperation for reflecting upon inter-institutional projects. I argue that the socio-cultural approach to collaboration has some important limitations that restrict ideological critic and emancipatory research. The limitations of this approach can be located in its epistemological assumptions, a homogenized notion of culture and a weakness in articulating the intrapersonal, inter-personal, inter-group/positional and social representational/ideological levels of analysis. As an empirical example of this I discuss the Sloan centres for family research.

Some critical reflections on the hiddenness argument

J.L. Schellenberg’s Argument from Divine Hiddenness maintains that if a perfectly loving God exists, then there is no non-resistant non-belief. Given that such nonbelief exists, however, it follows that there is no perfectly loving God. To support the conditional claim, Schellenberg presents conceptual and analogical considerations, which we subject to critical scrutiny. We also evaluate Schellenberg’s claim that the belief that God exists is logically necessary for entering into a relationship with the Divine. Finally, we turn to possible variants of Schellenberg’s case, and argue that the modifications necessary to accommodate our criticismas leave those variants with much less of a sting than originally suggested by his provocative formulation.     

Victim’s innocence, social categorization, and the threat to the belief in a just world

This research studies people’s reactions to the suffering of victims, examining the hypothesis of the belief in a just world (BJW) (Lerner, 1980) according to which the awareness of innocent victims threatens people’s BJW, and extending the scope of BJW theory to intergroup contexts. An implicit measure of the threat to the BJW (Hafer, 2000a) is used in this research. After participants viewed a videotaped film containing the victimization story they performed an emotional modified Stroop task. Study 1 examined the threat to the BJW as function of the innocence of the victim at an interpersonal level of analysis. Results show that only the innocent victim threatens the observer’s BJW. Study 2 examined the threat to the BJW as function of the victim’s group and of the victim’s innocence. Results show that an ingroup victim threatens the participant’s BJW more than a victim belonging to an outgroup.     

Traditional difference-score analyses of reasoning are flawed

Studies of the belief bias effect in syllogistic reasoning have relied on three traditional difference score measures: the logic index, belief index, and interaction index. Dube, Rotello, and Heit (2010, 2011) argued that the interaction index incorrectly assumes a linear receiver operating characteristic (ROC). Here, all three measures are addressed. Simulations indicated that traditional analyses of reasoning experiments are likely to lead to incorrect conclusions. Two new experiments examined the role of instructional manipulations on the belief bias effect. The form of the ROCs violated assumptions of traditional measures. In comparison, signal detection theory (SDT) model-based analyses were a better match for the form of the ROCs, and implied that belief bias and instructional manipulations are predominantly response bias effects. Finally, reanalyses of previous studies of conditional reasoning also showed non-linear ROCs, violating assumptions of traditional analyses. Overall, reasoning research using traditional measures is at risk of drawing incorrect conclusions.     

Memory indexing of sequential symptom processing in diagnostic reasoning

In diagnostic reasoning, knowledge about symptoms and their likely causes is retrieved to generate and update diagnostic hypotheses in memory. By letting participants learn about causes and symptoms in a spatial array, we could apply eye tracking during diagnostic reasoning to trace the activation level of hypotheses across a sequence of symptoms and to evaluate process models of diagnostic reasoning directly. Gaze allocation on former locations of symptom classes and possible causes reflected the diagnostic value of initial symptoms, the set of contending hypotheses, consistency checking, biased symptom processing in favor of the leading hypothesis, symptom rehearsal, and hypothesis change. Gaze behavior mapped the reasoning process and was not dominated by auditorily presented symptoms. Thus, memory indexing proved applicable for studying reasoning tasks involving linguistic input. Looking at nothing revealed memory activation because of a close link between conceptual and motor representations and was stable even after one week.     

Updating working memory in aircraft noise and speech noise causes different fMRI activations

The present study used fMRI/BOLD neuroimaging to investigate how visual‐verbal working memory is updated when exposed to three different background‐noise conditions: speech noise, aircraft noise and silence. The number‐updating task that was used can distinguish between “substitution processes,” which involve adding new items to the working memory representation and suppressing old items, and “exclusion processes,” which involve rejecting new items and maintaining an intact memory set. The current findings supported the findings of a previous study by showing that substitution activated the dorsolateral prefrontal cortex, the posterior medial frontal cortex and the parietal lobes, whereas exclusion activated the anterior medial frontal cortex. Moreover, the prefrontal cortex was activated more by substitution processes when exposed to background speech than when exposed to aircraft noise. These results indicate that (a) the prefrontal cortex plays a special role when task‐irrelevant materials should be denied access to working memory and (b) that, when compensating for different types of noise, either different cognitive mechanisms are involved or those cognitive mechanisms that are involved are involved to different degrees.     

What if you went to the police and accused your uncle of abuse? Misunderstandings concerning the benefits of memory distortion: A commentary on

In a recent paper, Fernández (2015) argues that memory distortion can have beneficial outcomes. Although we agree with this, we find his reasoning and examples flawed to such degree that they will lead to misunderstandings rather than clarification in the field of memory (distortion). In his paper, Fernández uses the terms belief and memory incorrectly, creating a conceptual blur. Also, Fernández tries to make the case that under certain circumstances, false memories of abuse are beneficial. We argue against this idea as the reasoning behind this claim is based on controversial assumptions such as repression. Although it is true that memory distortions can be beneficial, the examples sketched by Fernández are not in line with recent documentation in this area.     

Highly reflective reasoners show no signs of belief inhibition

The processes underlying individual differences in reasoning performance are not entirely understood. What do people who do well on reasoning tasks where beliefs and logic conflict do differently from other people? Because abundant evidence shows that even poorer reasoners detect these conflicts, it has been suggested that individual differences in reasoning performance arise from inhibition failures later in the reasoning process. The present paper argues that a minority of highly skilled reasoners may deviate from this general reasoning process from an early stage. Two studies investigated signs of belief inhibition using a lexical access paradigm (Study 1) and a negative priming paradigm (Study 2). Study 1 showed that while other people exhibited signs of belief inhibition following a belief–logic conflict, people with the highest disposition for cognitive reflection did not. In Study 2, this finding was replicated and similar results were also obtained when comparing groups with higher and lower general cognitive ability. Two possible explanations are discussed.     

认知控制子成分与客观风险对信任行为的影响

研究通过三个实验,在控制客观风险高低的同时,分别对刺激—反应一致性、任务转换和工作记忆负载进行操纵。结果发现,抑制控制在反应时上表现出差异,刺激—反应一致条件下被试做出信任的反应时更快;认知灵活性和工作记忆刷新在信任率上表现出差异,不转换条件和低工作记忆负载条件下被试的信任率更高。结果表明,抑制控制主要影响反应组织过程,认知灵活性和工作记忆刷新则会影响个体的信任决策过程。此外,客观风险对信任行为的影响表现出跨情境一致性,低风险条件下信任率更高。
