Is there a perfect state?:Experimental evidence from English and Spanish for the perfect-as-state hypothesis
No full textThe distinction between past and perfect has been subject to theoretical debate for decades. Some of the most prominent accounts argue that the perfect turns the mental representation of a past event into the mental representation of a state, based on a past event: the perfect-as-state hypothesis. This subtle distinction is notoriously difficult to trace, and has only been argued for using linguistic tests. Here, we provide evidence from two psycholinguistic experiments (total N=960), each in English and in Spanish, that operationalize stativity through event individuation. Our results show that compared to the past, the perfect leads to event construals that have more in common with states, both in English and in Spanish. These data constitute the first documentation of different event construals based on tenses that only differ in the subtlest of semantic distinctions
Navigating decision space:Causal structure improves performance in a branching choice task
No full textPrevious research has shown that the causal structure of events influences how well they are recalled in episodic memory later on. Here, we aimed to investigate whether these effects apply not only to events that are passively observed but also situations directly shaped by an individual’s decisions. We designed a task in which participants had to traverse decision trees of varying causal structure: ‘Coherent’ trees where each decision followed from the consequences of the preceding decision, and ‘fragmented’ trees where each subsequent decision was only statistically (but not causally) contingent on the preceding decision. In a between-subjects experiment, participants first completed an exploration phase in which they had to explore the decision trees without a specific goal; in a subsequent search phase, they had to reach a target outcome in as few attempts as possible. Analyses of participants’ performance showed that those in the coherent group required significantly fewer attempts to reach a correct outcome than those in the fragmented group. A follow-up experiment surprisingly found that the advantage of causal structure does not depend on episodic memory: Removing the exploration phase barely diminished the positive effect causal coherence had on participants’ performance. In further follow-up experiments without an exploration phase, neither the additional removal of ‘process images’ that show how a choice leads to an outcome, nor the removal of text labels describing decisions, was individually sufficient to equalize performances. Only when both were eliminated at once did participants perform equally well on coherent and fragmented trees. This indicates that cues relating to causal mechanisms (images) and predictive cues (text) each facilitate goal-directed decision making without relying on extensive learning, and that only the absence of both is sufficient to suppress the advantage causal structure provides
Policy Knowledge Production in De-democratizing Contexts
No full textIn an era of post-truth, the legitimacy of policy knowledge is questioned, especially in de-democratizing contexts where governments purposefully engage in post-truth politics to support their regimes. In such contexts, technocratic evidence-based policymaking is undermined, and the role played by policy advice changes. Recognizing the significance of political contextual factors that might differ across de-democratizing contexts, we analyzed how changes in policymaking and public administration in de-democratization contexts impact policy advice, focusing on think tanks in two de-democratizing countries of the European Union: Hungary and Poland. We identify four aspects of policymaking that are particularly consequential for the role of think tanks and the knowledge they produce in policymaking processes: questioning and politicizing expertise, centralizing policymaking, politicizing public administration, and dismantling accountability mechanisms. We argue that changes in policymaking along these four aspects are conducive to a controlled policy advice system, favoring short-term policy advice aligned with government ideology, while marginalizing and excluding the actors and knowledge that do not align. Our research, along with other literature on knowledge regimes in consolidated autocracies, suggests that control in these European Union–based contexts is not complete, and the think tank field continues to be characterized by diversity, particularly contestation and polarization between those who are aligned with the regime and those who oppose it. We substantiate our claims using an original interview dataset on think tanks in Hungary and Poland
