Stress has been implicated as a risk factor for the severity and progression of sporadic Alzheimer's disease (AD). Early life experiences determine stress responsivity in later life, and modulate age-dependent cognitive decline. Therefore, we examined whether early life experiences influence AD outcome in a bigenic mouse model which progressively develops combined tau and amyloid pathology (biA...

The Brief Implicit Association Test (BIAT) consists of two blocks of trials with the same four categories and stimulus-response mappings as the standard IAT, but with 1/3 the number of trials. Unlike the standard IAT, the BIAT focuses the subject on just two of each block's four categories. Experiments 1 and 2 demonstrated that attitude BIATs had satisfactory validity when good (but not bad) wa...

APP.V717I and Tau.P301L transgenic mice develop Alzheimer's disease pathology comprising important aspects of human disease including increased levels of amyloid peptides, cognitive and motor impairment, amyloid plaques and neurofibrillary tangles. The combined model, APP.V717I×Tau.P301L bigenic mice (biAT mice) exhibit aggravated amyloid and tau pathology with severe cognitive and behavioral d...

The comment articles in this issue by Friese and Fiedler (F&F) and by Rothermund and Wentura (R&W) offer perspectives on the validity of the Brief Implicit Association Test (BIAT) (Sriram & Greenwald, 2009; S&G). F&F concluded that construct validity of the BIAT can be established only by conducting studies that experimentally manipulate association strengths. We suggest that this conclusion ov...

BACKGROUND Doping attitude is a key variable in predicting athletes' intention to use forbidden performance enhancing drugs. Indirect reaction-time based attitude tests, such as the implicit association test, conceal the ultimate goal of measurement from the participant better than questionnaires. Indirect tests are especially useful when socially sensitive constructs such as attitudes towards ...

The Implicit Association Test (IAT) aims to measure participants' automatic evaluation of an attitude object and is useful especially for the measurement of attitudes related to socially sensitive subjects, e.g. doping in sports. Several studies indicate that IAT scores can be faked on instruction. But fully or semi-instructed research scenarios might not properly reflect what happens in more r...

A brief version of the Implicit Association Test (BIAT) has been introduced. The present research identified analytical best practices for overall psychometric performance of the BIAT. In 7 studies and multiple replications, we investigated analytic practices with several evaluation criteria: sensitivity to detecting known effects and group differences, internal consistency, relations with impl...

Purpose: Our goal was to determine the effectiveness of a brief online intervention designed to reduce stigma-relevant attitudes toward mentally ill individuals. We examined whether the experience of completing a Brief Implicit Association Test (BIAT) measuring attitudes toward people with mental illnesses alters explicit stigma in two studies. Methods: In Study 1, participants completed the BI...

The current study examined the effect of completing implicit association measures as an intervention to alter explicit stigma endorsement, when the intervention varies by mental illness content and implicit evaluation components. Volunteers (N=1549) aged 18-79 at an on-line research site completed either a mental illness, gay/straight, or non-evaluative Brief Implicit Association Test (BIAT) or...
