wetenschap24: Opvolger-van

Het is een brede theorie over menselijke waarneming en informatieverwerking, waarin doorgaans twee polen te onderscheiden zouden zijn: globale verwerking en locale verwerking. Een simpel voorbeeld is de Navon-taak, met het soort figuurtje dat ook in zijn tests gebruikt wordt: Globaal bekeken staat hier een letter H, lokaal bekeken staan er dertien letters L. Deze conceptuele tweedeling verklaart GLOMO van toepassing op vrijwel het complete scala van mentale activiteiten, met associaties als: Globale verwerking Lokale verwerking Goed humeur Slecht humeur Liefde Sex Op promotie gericht Op preventie gericht Laag niveau van autisme Hoog niveau van autisme Rechter hersenhelft Linker hersenhelft.

GLOMO zegt nog net niet: globaal = goed, lokaal = slecht, maar veel scheelt het niet. Förster heeft inmiddels gereageerd op het LOWI-rapport, en ontkent elk wangedrag. Werkelijk gedaan?

Science Mag: Fresh Misconduct Charges Hit Dutch Social Psychology - Kolfschooten. Replication Effort Provokes Praise—And 'Bullying' Charges. After a string of scandals involving accusations of misconduct and retracted papers, social psychology is engaged in intense self-examination—and the process is turning out to be painful.

Replication Effort Provokes Praise—And 'Bullying' Charges

This week, a global network of nearly 100 researchers unveiled the results of an effort to replicate 27 well-known studies in the field. In more than half of the cases, the result was a partial or complete failure. As the replicators see it, the failed do-overs are a healthy corrective. “Replication helps us make sure what we think is true really is true,” says Brent Donnellan, a psychologist at Michigan State University in East Lansing who has undertaken three recent replications of studies from other groups—all of which came out negative. “We are moving forward as a science,” he says. But rather than a renaissance, some researchers on the receiving end of this organized replication effort see an inquisition. Schnall, however, says that her work was “defamed.” Trial by p-values: Preliminary thoughts on the Jens Förster report.

I’ve just had a quick look at the report (available at Retraction Watch) that led to the investigation of Jens Förster for possible data manipulation.

Trial by p-values: Preliminary thoughts on the Jens Förster report

It makes the case that the data in three of Förster’s papers are statistically highly improbable, largely due to the fact that the means for the levels of various three-level factors all tend to fall in a straight line. There are also claims about the data being far too consistent across independent studies, of effect sizes being implausibly large, and demographically implausible samples. It is dry, depressing reading. From the comments I’ve seen on Retraction Watch and Twitter, some people are already convinced. For my part, I’m reserving judgment until the psychological/statistical community has time to complete its “post-publication peer review” of the report. 1. 2.

Fresh Misconduct Charges Hit Dutch Social Psychology

"Here we go again," another lamented. Scientists here are still searching their souls about two previous scandals—involving Diederik Stapel of the Tilburg University in 2011 and Dirk Smeesters of Erasmus University in Rotterdam a year later. Now they have learned that a national research integrity panel has found evidence of data manipulation in the work of Jens Förster, a social psychologist at the University of Amsterdam (UvA).

The university has already announced that it will request the retraction of one of Förster's articles. The case is drawing widespread international attention as well, in part because Förster, who's German and came to Amsterdam in 2007, enjoys a sterling reputation. The case started in September 2012, when a whistleblower sent UvA a 35-page complaint about three of Förster’s studies. Intrigued, the researcher asked Förster to send him raw data from the experiments. Kolfschooten : Vakgenoten dringen aan op breder... Martinenserink : @BrianNosek posted his email... New Dutch psychology scandal? Inquiry cites data manipulation, calls for retraction. The University of Amsterdam has called for the retraction of a 2011 paper by two psychology researchers after a school investigation concluded that the article contained bogus data, the Dutch press are reporting.

New Dutch psychology scandal? Inquiry cites data manipulation, calls for retraction

The paper, “Sense Creative! The Impact of Global and Local Vision, Hearing, Touching, Tasting and Smelling on Creative and Analytic Thought,” was written by Jens Förster and Markus Denzler and published in Social Psychological & Personality Science. It purported to find that: Holistic (global) versus elemental (local) perception reflects a prominent distinction in psychology; however, so far it has almost entirely been examined in the domain of vision.

Current work suggests that global/local processing styles operate across sensory modalities. But according to this article in the NRC Handelsblad (with an assist from Google Translate): Social psychologist Förster denies misconduct, calls charge “terrible misjudgment” Retraction Watch has obtained an email from Jens Förster, the social psychologist in the Netherlands who, as Dutch media reported this week, was the target of a misconduct investigation at the University of Amsterdam.

Social psychologist Förster denies misconduct, calls charge “terrible misjudgment”

The inquiry led to the call for the retraction of a paper by Förster and a colleague, Markus Denzler, over concerns of data manipulation. Förster denies those claims and said Denzler was not involved in the heavy lifting for the study in question: This is an English translation of my reaction to a newspaper article that appeared in the Dutch newspaper NRC about me.Today, an article appeared in the Dutch newspaper “NRC” summarizing an investigation on my academic integrity that was opened in September 2012.

As we reported earlier, Förster has denied any wrongdoing in the matter. But as the report makes clear, investigators caught several red flags in Förster’s work.

Jens Förster Last week we wrote about the 2012 complaint that triggered the investigation into Jens Förster, the social psychologist at the University of Amsterdam whose work has come under scrutiny for possible fraud. Now we have the findings of the official investigation by Landelijk Orgaan Wetenschappelijke Integriteit (the Dutch National Board for Scientific Integrity, often referred to as LOWI) — which clearly indicates that the institution believes Förster made up results. Here are some of the highlights from the document, which we’ve had translated by a Dutch speaker: “I never manipulated data”: Förster defends actions in open letter.

Jens Förster, the Dutch social psychologist accused of misconduct, has posted an open letter on his lab’s website in which he denies wrongdoing. The letter, in English and dated May 11, offers a detailed rebuttal to the investigation’s conclusions. It also offers a rationale for Förster’s decision not to post his data on the Internet. And it’s followed by a briefer letter from Nira Liberman, who identifies herself as a collaborator of Förster’s. JelteWicherts : Mmm. I wonder where Jens Förster... Uri Simonsohn Data Colada. Recently, a psychology paper (.pdf) was flagged as possibly fraudulent based on statistical analyses (.pdf). The author defended his paper (.html), but the university committee investigating misconduct concluded it had occurred (.pdf). In this post we present new and more intuitive versions of the analyses that flagged the paper as possibly fraudulent.

We then rule out p-hacking among other benign explanation. Excessive linearityThe whistleblowing report pointed out the suspicious paper had excessively linear results. That sounds more technical than it is. Imagine comparing the heights of kids in first, second, and third grade, with the hypothesis that higher grades have taller children. The scrutinized paper has 12 studies with three conditions each. Our new analysis of excessive linearity The original report estimated a less than 1 in 179 million chance that a single paper with 12 studies would lead to such perfectly linear results. Never. A second witness. Never. Gill1109 : Uri #Simonsohn weighs in on... Simonsohn’s Fraud Detection Technique Revealed » Random Assignment.

Explaining The Oddness of Jens Förster's Data - Neuroskeptic. Three weeks ago I covered the story of Jens Förster, the German social psychologist who was accused of scientific misconduct after statisticians noted unusual patterns in his published data. More evidence has come to light since then, but there are still no clear answers as to what really happened.

In this post, I examine the data and conclude that data fabrication – whoever is responsible for it – is the only plausible scenario.
