Inducing inhibition affects propagation of uncertainty and checking behaviors

Hodaya Adler, Renana Eitan & Omer Linkovski

Published: September 2024, Current Psychology.

This study evaluated how inducing inhibition affects resolution of uncertainty and checking separately. Our results indicate that inducing inhibition reduces unnecessary checking in “certainty” trials. Inducing inhibition also improves accuracy in “uncertainty” trials when checking is impossible, by limiting the harmful propagation of uncertainty.

Increased activation product of complement 4 protein in plasma of individuals with schizophrenia
 


Published: 22 September 2021

Structural variation in the complement 4 gene (C4) confers genetic risk for schizophrenia. The variation includes numbers of the increased C4A copy number, which predicts increased C4A mRNA expression. C4-anaphylatoxin (C4-ana) is a C4 protein fragment released upon C4 protein activation that has the potential

Examining subjective sleep quality in adults with hoarding disorder

Mahnke, A.*, Linkovski, O.*, Timpano, K., Sanchez, C., Varias, A., Filippou-Frye, M., Blasey, C., Bernert, R., & Rodriguez, C. I.
Published: Journal of Psychiatric Research, 2021.

Hoarding disorder (HD), characterized by difficulty parting with possessions and functionally impairing clutter, affects 2–6% of the population. Originally considered part of Obsessive-Compulsive Disorder (OCD), HD became a distinct diagnostic entity in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) in 2013. While sleep impacts OCD, little is known about sleep in HD. As HD patients often report poor sleep

Why Check? A meta-analysis of checking in Obsessive-Compulsive Disorder: Threat vs. Distrust of Senses

Strauss, Y. A., Fradkin, I., McNally, J. R., Linkovski, O., Anholt, G., Huppert D. J.
Published: Clinical Psychology Review, 2020

Compulsive checking is the most common ritual among individuals with obsessive-compulsive disorder (OCD). Yet, other than uncertainty, the variables prompting checking are not fully understood. Laboratory studies suggest that task conditions - whether threatening (anxiety-relevant) or neutral, and task type - whether requiring perceptual or reasoning decision-making – may be influential. The purpose of our...

Exploring BDNF Val66Met polymorphism and ketamine response in Obsessive-Compulsive Disorder: A preliminary study

Published: Journal of Clinical Psychopharmacology, 2019

Acommon single-nucleotide polymorphism (SNP) in the human brain derived neurotrophic factor (BDNF) gene (Val66Met; rs6265) has been reported to alter extinction learning in human carriers and knock-in mice with the SNP. Extinction learning is a major component of behavioral therapies for anxiety disorders...

Beyond uncertainty: a broader scope for incentive hope mechanisms and its implications

Linkovski, O., Weinbach, N., Edelman, S., Feldman M. W., Lotem, A., & Kolodny, O.
Published: Behavioral and Brain Sciences, 2019

We propose that food-related uncertainty is but one of multiple cues that predicts harsh conditions and may activate “incentive hope.” An evolutionarily adaptive response to these would have been to shift to a behavioral-metabolic phenotype geared toward facing hardship. In modernity, this phenotype may lead to pathologies such as obesity and hoarding. Our perspective suggests a novel therapeutic approach...

Inhibiting uncertainty: priming inhibition promotes reduction of uncertainty

Kalanthroff, E.,* Linkovski, O.,* Anholt, G., & Henik, A.
Published: Neuropsychologia, 2016

Uncertainty affects performance in many cognitive tasks, including the visual-search task, and individual differences in the experience of uncertainty may contribute to several psychological disorders. Despite the importance of uncertainty, to date, no study has explained the basic mechanisms underlying individual differences in the experience of uncertainty. However, it has been suggested that inhibition, a cognitive... 

Stop checking: Repeated checking and its effects on response inhibition and doubt

Linkovski, O., Kalanthroff, E., Anholt, G., & Henik, A.
Published: Journal of Behavior Therapy and Experimental Psychiatry, 2016

Repeated checking is a common ritual in obsessive-compulsive disorder (OCD). van den Hout and Kindt (2003b) devised a task demonstrating paradoxical reductions in memory confidence following repeated checking. This effect was later found to be contingent upon response inhibition. The current study aims to...

Musical space synesthesia: Automatic, explicit and conceptual connections between musical stimuli and space

Akiva-Kabiri, L.,* Linkovski, O.,* Gertner, L., & Henik, A.
Published: Consciousness and Cognition, 2014

In musical–space synesthesia, musical pitches are perceived as having a spatially defined array. Previous studies showed that symbolic inducers (e.g., numbers, months) can modulate response according to the inducer’s relative position on the synesthetic spatial form. In the current study we tested two musical–space..
