Depth Perception and Spatial Vision01:15

Depth Perception and Spatial Vision

Depth perception is the ability to perceive objects three-dimensionally. It relies on two types of cues: binocular and monocular. Binocular cues depend on the combination of images from both eyes and how the eyes work together. Since the eyes are in slightly different positions, each eye captures a slightly different image. This disparity between images, known as binocular disparity, helps the brain interpret depth. When the brain compares these images, it determines the distance to an object.
Impact of Schemas01:30

Impact of Schemas

Schemas are cognitive structures that provide a framework for interpreting and organizing social information. They help individuals navigate complex environments by offering expectations about people, events, and behaviors. Schemas influence attention, encoding, and retrieval processes, thereby shaping the entire trajectory of information processing in social contexts.Attention and Cognitive LoadDuring initial attention, schemas function as filters that prioritize schema-consistent information,...

Area of Science:

  • Cognitive Neuroscience
  • Psychology
  • Neuroscience

Background:

  • Top-down attentional control is known to influence perception.
  • Its impact on memory functions, particularly visual short-term memory (VSTM), is less understood.
  • Investigating attentional biases on mnemonic functions is crucial for a comprehensive understanding of cognitive control.

Purpose of the Study:

  • To investigate if spatial orienting of attention can bias visual short-term memory (VSTM) functions.
  • To explore the neural mechanisms underlying attentional influence on VSTM search.
  • To determine if voluntary control can modulate memory search processes.

Main Methods:

  • Combined behavioral measures and event-related potentials (ERPs).
  • Participants viewed item arrays, received spatial or neutral retro-cues, and then identified probe items.
  • Manipulated VSTM load (1, 2, or 4 items) and retro-cue validity.

Main Results:

  • Spatial retro-cues improved accuracy and response times in VSTM tasks, mitigating VSTM load effects.
  • A novel ERP component (N3(RS)) related to VSTM search was identified, increasing with VSTM load.
  • The N3(RS) component was absent when spatial retro-cues were used, indicating attentional modulation.

Conclusions:

  • Attentional biases extend to mnemonic functions, influencing VSTM.
  • Searching for items within VSTM is subject to flexible, voluntary control.
  • Spatial attention plays a significant role in modulating VSTM search efficiency and neural correlates.
