Congratulations to Dr. Noam Markovitch

24 May, 2023

For receiving the best doctoral award in developmental psychology from the APA organization!
Noam's doctorate deals with the understanding of children's differential sensitivity to the effects of the environment on their development. The work's contribution to developmental psychology is very significant, both in theoretical thought and methodological approaches.
Well done Noam!
Noam PhD supervisor, Prof. Ariel Knafo-Noam, has also won the award in the past

 

From acute stress to persistent post-concussion symptoms: The role of parental accommodation and child’s coping strategies

19 April, 2023

An article by PhD candidate Irit Aviv, supervised by Dr. Tammy Pilowsky Peleg and Prof. Hillel Aviezer was selected as the winner of the Eighth Annual TCN/AACN student Project Competition, from among 15 eligible manuscripts

Acute stress following mild Traumatic Brain Injury (mTBI) is highly prevalent and associated with Persistent Post-Concussion symptoms (PPCS). However, the mechanism mediating this relationship is understudied.

Mu rhythm suppression over sensorimotor regions is associated with greater empathic accuracy

23 March, 2022

Multiple brain systems are engaged when we try to understand people's emotions, including parts of the sensorimotor cortex associated with motor simulation. Simulation-related brain activity is described as a 'low-level' component of empathy - however its contribution to complex empathic judgments is unclear.

A new Study by Shir Genzer from Dr. Anat Perry lab, published in Social Cognitive & Affective Neuroscience, investigated this question and examined the association between empathic accuracy, the ability to accurately infer the emotional states of others, and mu rhythm suppression, an EEG index of sensorimotor cortex-based simulation. Specifically, they investigated how different information channels (visual information, audio information and their combination) effect the association between mu rhythm suppression and empathic accuracy.

The results from two experiments (one with US sample and the other with Israeli sample) indicated that sensorimotor representations play a role not only in low-level motor simulation, but also in higher-level inferences about others' emotions, especially when visual cues are crucial for accuracy.
