Summary
Visual tracking is influenced by facial emotions, especially fear, but only when attention is not overloaded. Social cues impact how we follow moving objects.
Area of Science:
- Cognitive Science
- Visual Perception
- Social Cognition
Background:
- Classical theories propose visual tracking relies on pre-attentive, low-level visual mechanisms.
- The role of high-level social information in dynamic visual tracking remains debated.
Purpose of the Study:
- To investigate if facial expressions influence multiple object tracking.
- To determine how attentional load affects the impact of facial emotion on visual tracking.
Main Methods:
- Participants performed a multiple object tracking task involving faces with varying emotional expressions.
- Attentional load was manipulated across experimental conditions.
Main Results:
- Tracking performance was enhanced for fearful faces compared to neutral faces.
- This emotional advantage was observed only under low attentional load.
- Distractor face emotion did not affect tracking performance.
Conclusions:
- Dynamic visual tracking is not solely a low-level process and can be modulated by social cues like facial expressions.
- The influence of facial expressions on tracking is dependent on the availability of attentional resources.

01:23Regulation of Expression at Multiple Steps
1.4K
The gene expression in cells is regulated at different stages: (i) transcription, (ii) RNA processing, (iii) RNA localization, and (iv) translation. Transcriptional regulation is mediated by regulatory proteins such as transcription factors, activators, or repressors—these control gene expression by initiating or inhibiting the transcription of genes. Once a precursor or pre-mRNA is produced, it undergoes post-transcriptional modification, including 5' capping, splicing, and the...

Gene expression can be regulated at almost every step from gene to protein. Transcription is the step that is most commonly regulated. This involves the binding of proteins to short regulatory sequences on the DNA. This association can either promote or inhibit the transcription of a gene associated with the respective sequence.
Transcription results in the generation of precursor (pre-mRNA) that consists of both exons and introns, which needs further processing before being translated to a...

Multiple regression assesses a linear relationship between one response or dependent variable and two or more independent variables. It has many practical applications.
Farmers can use multiple regression to determine the crop yield based on more than one factor, such as water availability, fertilizer, soil properties, etc. Here, the crop yield is the response or dependent variable as it depends on the other independent variables. The analysis requires the construction of a scatter plot...

Overview
Gene expression is the process in which DNA directs the synthesis of functional products, that is, proteins. Cells can regulate gene expression at various stages. It allows organisms to generate different cell types and enables cells to adapt to internal and external factors.
Genetic Information Flows from DNA to RNA to Protein
A gene is a stretch of DNA that serves as the blueprint for functional RNAs and proteins. Since DNA is made up of nucleotides and proteins consist of amino...
