Science is often perceived to be a self-correcting enterprise. In principle, the assessment of scientific claims supposed proceed in cumulative fashion, with reigning theories day progressively approximating truth more accurately over time. practice, however, self-correction tends less efficiently than one might naively suppose. Far from evaluating new evidence dispassionately and infallibly, individual scientists cling stubbornly prior findings. Here we explore dynamics at an rather...

Continuous flash suppression (CFS) has been used as a paradigm to probe the extent which word stimuli are processed in absence of awareness. In two experiments reported here, no evidence is obtained that up semantic level when suppressed through CFS. Experiment 1, did not break faster than their pseudo-word variants nor was time modulated by frequency. 2 replicated these findings, but more critically showed differential effects can be with this using simpler stimulus. addition, pixel density...

The present research examines the nature of different processes that have been proposed to underlie semantic priming. Specifically, it has argued priming arises as a result automatic target activation and/or use strategies like prospective expectancy generation and retrospective matching. This article investigates extent these rely on cognitive resources by experimentally manipulating working memory load. To disentangle processes, prime-target pairs were selected such they symmetrically...

Increased execution of replication studies contributes to the effort restore credibility empirical research. However, a second generation problems arises: number potential targets is at serious mismatch with available resources. Given limited resources, target selection should be well-justified, systematic and transparently communicated. At present discussion on what consider when selecting theoretical discussion, self-reported justifications few formalized suggestions. In this Registered...

Dishonesty is an intriguing phenomenon, studied extensively across various disciplines due to its impact on people’s lives as well society in general. To examine dishonesty a controlled setting, researchers have developed number of experimental paradigms. One the most popular approaches this regard, matrix task, which participants receive matrices wherein they find two numbers that sum 10 (e.g., 4.81 and 5.19), under time pressure. In next phase, need report how many had solved correctly,...

Abstract Tools like ChatGPT, which allow people to unlock the potential of large language models (LLMs), have taken world by storm. ChatGPT’s ability produce written output remarkable quality has inspired, or forced, academics consider its consequences for both research and education. In particular, question what constitutes authorship, how evaluate (scientific) contributions received a lot attention. However, impact on (online) human data collection mostly flown under radar. The current...

The present study investigated people's understanding of underinformative sentences like 'Some oaks are trees'. Specifically, the scalar term 'some' can be interpreted pragmatically, Not all trees, or logically, some and possibly trees. aim this was to capture interindividual variability in interpretation such sentences. In two experiments, participants provided truth value judgments for 20 on which a latent class analysis performed. results revealed three classes: consistent pragmatic...

Sharing research data allows the scientific community to verify and build upon published work. However, sharing is not common practice yet. The reasons for are myriad: Some practical, others more fear-related. One particular fear that a reanalysis may expose errors. For this explanation, it would be interesting know whether authors do share genuinely made errors than who data. (Wicherts, Bakker Molenaar 2011) examined can discovered based on manuscript only, because impossible reanalyze...

Semantic priming, the phenomenon that a target is recognized faster if it preceded by semantically related prime, well-established effect. However, mechanisms producing semantic priming are subject of debate. Several theories assume underlying processes controllable and tuned to prime utility. In contrast, purely automatic processes, like spreading activation, should be independent prime's usefulness. The present study sought disentangle both accounts creating situation where processing...

Recent advances in the field of computational linguistics have led to development various prediction-based models semantics. These seek infer word representations from large text collections by predicting target words neighbouring (or vice versa). The resulting are vectors a continuous space, collectively called embeddings. Although psychological plausibility was not primary concern for developers predictive models, it has been topic several recent studies psycholinguistics. That is,...

The present study investigated the relationship between category extension and intension for eleven different semantic categories.It is often tacitly assumed that there a (strong) extension-intension link.However, recent by Hampton Passanisi (2016) examining patterns of stable individual differences in concepts across participants called this hypothesis into question.To conceptually replicate their findings, two studies were conducted.We employed judgment task to measure extensions, whereas...
