The complex relationship between attention and visual perception can be exemplified and investigated through the Attentional Blink. The attentional blink is characterised by impaired attention to the second of two target stimuli, when both occur within 200 - 500ms. The attentional blink has been well studied in experimental lab settings. However, despite the rise of online methods for behavioural research, their suitability for studying the attentional blink has not been fully addressed yet, the main concern being the lack of control and timing variability for stimulus presentation. Here, we investigated the suitability of online testing for studying the attentional blink with visual objects. Our results show a clear attentional blink effect between 200 to 400ms following the distractor including a Lag 1 sparing effect in line with previous research despite significant inter-subject and timing variability. This work demonstrates the suitability of online methods for studying the attentional blink with visual objects, opening new avenues to explore its underlying processes.

Background And Aims: Uncontrollable gaming behavior is a core symptom of Internet Gaming Disorder (IGD). Attentional bias towards game-related cues may contribute to the difficulty in regulating online gaming behavior. However, the context-specific attentional bias and its cognitive mechanisms in individuals with IGD have not been systematically investigated.

Article Synopsis
  • Driving involves complex coordination that deteriorates with age, affecting cognitive and motor functions.
  • A study compared blink behavior and neural responses in younger and older adults during reactive and proactive driving tasks, revealing that younger participants had shorter blink durations and more efficient neural processing.
  • Functional connectivity analysis indicated that younger adults exhibit stronger network integration in various brain areas, while older adults showed signs of compensatory mechanisms in attention networks, suggesting adaptability in response to cognitive demands.

In the attentional blink paradigm, participants attempt to identify two targets appearing in a rapidly presented stream of distractors. Report accuracy is typically high for the first target (T1) while identification of the second target (T2) is impaired when it follows within about 200-400 ms of T1. An important question is whether T2 is processed to a semantic level even when participants are unaware of its identity.

Long-term effects of concussion on attention, sensory gating and motor learning.

The current work aimed to understand the behavioral manifestations that result from disruptions to the selective facilitation of task-relevant sensory information at early cortical processing stages in those with a history of concussion. A total of 40 participants were recruited to participate in this study, with 25 in the concussion history group (Hx) and 15 in the control group (No-Hx). Somatosensory-evoked potentials (SEPs) were elicited via median nerve stimulation while subjects performed a task that manipulated their focus of attention toward or away from proprioceptive cues.
