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.

Rhythmic modulation of visual discrimination is linked to individuals' spontaneous motor tempo

Rhythmic modulation of visual discrimination is linked to individuals' spontaneous motor tempo

The impact of external rhythmic structure on perception has been demonstrated across different modalities and experimental paradigms. However, recent findings emphasize substantial individual differences in rhythm-based perceptual modulation. Here, PhD candidate Leah Snapiri, Nir Shalev and Yael Kaplan from Prof. Ayelet Landau lab examine the link between spontaneous rhythmic preferences, as measured through the motor system, and individual differences in rhythmic modulation of visual discrimination.

As a first step, we measure individual rhythmic preferences using the spontaneous tapping task. Then we assess perceptual rhythmic modulation using a visual discrimination task in which targets can appear either in-phase or out-of-phase with a preceding rhythmic stream of visual stimuli. The tempo of the preceding stream was manipulated over different experimental blocks (0.77 Hz, 1.4 Hz, 2 Hz).

We find that visual rhythmic stimulation modulates discrimination performance. The modulation is dependent on the tempo of stimulation, with maximal perceptual benefits for the slowest tempo of stimulation (0.77 Hz). Most importantly, the strength of modulation is also linked to individuals' spontaneous motor tempo. Individuals with slower spontaneous tempi show greater rhythmic modulation compared to individuals with faster spontaneous tempi. This finding suggests that different tempi affect the cognitive system with varying levels of efficiency and that self-generated rhythms impact our ability to utilize rhythmic structure in the environment for guiding perception and performance.
