After decades of using mostly college students, researchers in psychology and social sciences gradually moved online to more cost-effective and flexible audiences. First, to samples of online convenience (CraigsList, Facebook), and then to sophisticated markets like Amazon's Mechanical Turk (MTurk). Now, advanced platforms (such as CloudResearch an...

We show that the use of large language models (LLMs) is prevalent among crowd workers, and that targeted mitigation strategies can significantly reduce, but not eliminate, LLM use. On a text summarization task where workers were not directed in any way regarding their LLM use, the estimated prevalence of LLM use was around 30%, but was reduced by a...

Introduction Recent work challenged past findings that documented relational memory impairments in autism. Previous studies often relied solely on explicit behavioral responses to assess relational memory integrity, but successful performance on behavioral tasks may rely on other cognitive abilities (e.g., executive functioning) that are impacted i...

With the ever-increasing adoption of tools for online research, for the first time we have visibility on macro-level trends in research that were previously unattainable. However, until now this data has been siloed within company databases and unavailable to researchers. Between them, the online study creation and hosting tool Gorilla Experiment B...

After decades of using mostly college students, behavioral researchers gradually moved online to more cost-effective and flexible audiences, first to samples of convenience and then to sophisticated markets like Amazon’s Mechanical Turk (MTurk). Now, advanced platforms (such as CloudResearch and Prolific) promise researchers higher data quality usi...

This erratum reports on a technical error that was discovered in Study 2 of Peer et al. (2021). Because of this technical error, some specific findings on participants’ proclivity for dishonesty reported in the paper have been found incorrect. We detail the error, which only affected female participants, and its impact on the findings and report on...

We examine key aspects of data quality for online behavioral research between selected platforms (Amazon Mechanical Turk, CloudResearch, and Prolific) and panels (Qualtrics and Dynata). To identify the key aspects of data quality, we first engaged with the behavioral research community to discover which aspects are most critical to researchers and...

Misinformation often affects inferential reasoning even after it has been retracted, known as the continued influence effect (CIE). Previous behavioural research into the effect’s underlying mechanisms has focussed on the role of long-term memory processes at the time misinformation is retrieved during inferential reasoning. We present the first in...

Background It remains unclear whether executive control (EC) deficits in autism spectrum disorders (ASD) represent a failure in proactive EC (engaged and maintained before a cognitively demanding event), or reactive EC (engaged transiently as the event occurs). We addressed this question by administering a paradigm investigating components of EC in...

Despite the clinically significant impact of executive dysfunction on the outcomes of adolescents and young adults with autism spectrum disorders (ASD), we lack a clear understanding of its prevalence, profile, and development. To address this gap, we administered the NIH Toolbox Cognition Battery to a cross‐sectional Intelligence Quotient (IQ) cas...

Although autism spectrum disorder (ASD) is characterized by deficits in cognitive control, our previous work has shown that preparatory, goal-directed cognitive processing (proactive control) may be preserved in children with ASD. We investigated whether proactive control is intact in adolescents and young adults with ASD, as well as how symptoms o...

Research has observed evidence for both hypo-(supposedly due to a broken mirror neuron system) and hyper-(thought to be the result of deficits in adaptive control) imitation in autism spectrum disorder (ASD). This work sought to adjudicate between these findings using an automatic imitation (AI) paradigm with the novel manipulation of the need to e...

Misinformation – information that is false or inaccurate – can continue to influence people’s memory and reasoning even after it has been corrected. Researchers have termed this the continued influence effect (CIE). However, to date, research has focused exclusively on examining the CIE in a single polarity, namely the ongoing effect of initially a...

Upon receiving a correction, initially presented misinformation often continues to influence people's judgment and reasoning. Whereas some researchers believe that this so-called continued influence effect of misinformation (CIEM) simply arises from the insufficient encoding and integration of corrective claims, others assume that it arises from a...

A plethora of behavioural research has suggested that the successful encoding of retracting information is required to minimise the lingering effects of misinformation. However, neuroscientific research in this area is much scarcer. Participants (n = 34) completed a typical continued-influence misinformation paradigm whilst electroencephalographic...

Misinformation often affects inferences and judgments even after it has been retracted. This is known as the continued influence effect (CIE). Previous behavioural research into the effect’s underlying mechanisms has focussed on the role of long-term memory processes at the time misinformation is retrieved during inferential reasoning and judgments...

It is well known that information that is initially thought to be correct but then revealed to be false, often continues to influence human judgement and decision making despite people being aware of the retraction. Yet little research has examined the underlying neural substrates of this phenomenon, which is known as the 'continued influence effec...
