Irrelevant Stimuli and Action Control: Analyzing the Influence of Ignored Stimuli via the Distractor-Response Binding Paradigm

1Cognitive Psychology Unit, Institute of Psychology, Trier University, 2Clinical Psychophysiology Unit, Institute of Psychobiology, Trier University


JoVE 51571

The distractor-response binding paradigm is described. It can be used to shed light on the influence irrelevant stimuli, competing with targets for a response, can have on human action. Both response retrieval effects and distractor inhibition effects can be analyzed within the paradigm.

Using the Threat Probability Task to Assess Anxiety and Fear During Uncertain and Certain Threat

1Department of Psychology, University of Wisconsin-Madison


JoVE 51905

Potentiation of the startle reflex is measured via electromyography of the orbicularis oculi muscle during low (uncertain) and high (certain) probability electric shock threat in the Threat Probability Task. This provides an objective measure of distinct negative emotional states (fear/anxiety) for research on psychopathology, substance use/abuse, and broad affective science.

Perceptual and Category Processing of the Uncanny Valley Hypothesis' Dimension of Human Likeness: Some Methodological Issues

1Department of Neuropsychology, University of Zurich


JoVE 4375

Investigation of the Uncanny Valley Hypothesis and affective experience requires an understanding of the hypothesis' dimension of human likeness (DHL). This protocol allows representation of the DHL and examination of categorical perception. Use of the same stimuli and fMRI to distinguish brain regions responsive to physical and category change is illustrated.

A Proboscis Extension Response Protocol for Investigating Behavioral Plasticity in Insects: Application to Basic, Biomedical, and Agricultural Research

1School of Life Sciences, Arizona State University


JoVE 51057

The Proboscis Extension Response (PER) conditioning protocol, developed for the honey bee (Apis mellifera), provides an ecologically-relevant and easily quantifiable means for studying several different mechanisms of learning in many insect species.

How to Detect Amygdala Activity with Magnetoencephalography using Source Imaging

1Department of Psychology, University of Wisconsin-Milwaukee, 2McConnell Brain Imaging Centre, Montreal Neurological Institute, McGill University, 3Department of Neurology, Medical College of Wisconsin


JoVE 50212

This article describes how to record amygdala activity with magnetoencephalography (MEG). In addition this article will describe how to conduct trace fear conditioning without awareness, a task that activates the amygdala. It will cover 3 topics: 1) Designing a trace conditioning paradigm using backward masking to manipulate awareness. 2) Recording brain activity during the task using magnetoencephalography. 3) Using source imaging to recover signal from subcortical structures.

Eye Tracking, Cortisol, and a Sleep vs. Wake Consolidation Delay: Combining Methods to Uncover an Interactive Effect of Sleep and Cortisol on Memory

1Department of Psychology, Boston College, 2Department of Psychology, Wofford College, 3Department of Psychology, University of Notre Dame


JoVE 51500

We present a protocol used to discover an interactive effect between sleep and cortisol on memory consolidation, particularly for negative arousing images. Specifically, the experimental design utilizes eye tracking, salivary cortisol analysis, and behavioral memory testing – methods that can be used with both healthy and clinical participants.

Extinction Training During the Reconsolidation Window Prevents Recovery of Fear

1Departments of Psychiatry and Neuroscience, and Friedman Brain Institute, Mt. Sinai School of Medicine, 2Department of Psychology, New York University, 3Department of Psychology and Center for Neural Science, New York University


JoVE 3893

Conditioned fear can be diminished through an inhibitory process called extinction, but can resurface under conditions such as the passage of time or exposure to stress. Our protocol presents a novel way of preventing fear recovery by introducing extinction during the reconsolidation window (the re-storage phase of a reactivated memory).

Using Eye Movements to Evaluate the Cognitive Processes Involved in Text Comprehension

1Department of Psychology, University of Illinois at Chicago


JoVE 50780

The present article describes how to use eye tracking methodologies to study the cognitive processes involved in text comprehension. Descriptions of eye tracking equipment, how to develop experimental stimuli, and procedural recommendations are included. The information presented can be applied to most any study using verbal stimuli.

The Crossmodal Congruency Task as a Means to Obtain an Objective Behavioral Measure in the Rubber Hand Illusion Paradigm

1Department of Cognitive Science, Macquarie University, 2ARC Centre of Excellence in Cognition and its Disorders, Macquarie University, 3Department of Psychology, Macquarie University


JoVE 50530

We demonstrate how an objective measure can be employed in the widely employed rubber hand illusion paradigm. This measure is obtained by modifying the well-established crossmodal congruency task. This task allows the investigation of multisensory processes which are critical for modulations of body representations as in the rubber hand illusion.

Automated, Quantitative Cognitive/Behavioral Screening of Mice: For Genetics, Pharmacology, Animal Cognition and Undergraduate Instruction

1Department of Psychology, Rutgers University, 2Department of Psychology, Koç University, 3Center for Neural Science, New York University, 4Department of Mathematics & Computer Science, Fairfield University


JoVE 51047

Fully automated system for measuring physiologically meaningful properties of the mechanisms mediating spatial localization, temporal localization, duration, rate and probability estimation, risk assessment, impulsivity, and the accuracy and precision of memory, in order to assess the effects of genetic and pharmacological manipulations on foundational mechanisms of cognition in mice.
