Exploring The Attentional Blink To Emotional Facial Expressions In Different Level Of Trait Anxiety

In the modern society, there are a lot of information, these stimuli is not constant over time but instead fluctuates from moment to moment. due to the limited resources of the attention of the human’ nervous system, only a small sub-set of the available information that is coming through the senses is granted access to the brain processes that form the basis of consciously accessible working memory representations. Attention is a cognitive mechanism that helps to select and process important or interesting information, while irrelevant information is largely ignored. How to choose useful information is an important issue of psychological processes. The Attentional Blink has been primarily in the focus of investigations of the time course of selective attention, rapid serial visual presentation (RSVP) paradigms are widely used. In these paradigms, two targets have to be reported in a stream of rapidly succeeding stimuli. If two task-relevant targets appear in close temporal proximity within a stream of irrelevant distracters, a period of limited awareness for the second target, called the AB, is often observed. The AB reflects a deficit in reporting the second target (T2) in case it follows the first task-relevant target (T1) with a temporal delay of200-500ms.Trait Anxiety is considered as a kind of Personality trait. It is the stable individual difference from the perspective of anxiety tendency. A growing body of literature is focusing on Trait Anxiety and the Attentional Blink, Most studies have addressed the question of how multiple stimuli are processed when they are presented simultaneously in a single spatial array. Therefore, we use a rapid serial visual presentation paradigm to investigate the selective attention to emotional facial expressions in Different Level of Trait Anxiety.In present study, we used RSVP paradigm, Each probe was presented for83millisecond with no break between the faces. The present study includes three experiments.The studyl:using State-Trait Anxiety Inventory (STAI-T) to test participants’ Trait Anxiety, there are76participants, in which39for High Trait Anxiety group and37for Low Trait Anxiety group. The first experiment use dual task conditions of RVSP. The aim of the first study was to explore whether the appearance of an angry face (as a first stimulus) may result in a relatively strong deterioration of the detection of a subsequently appearing neural face (i. e., enhanced attentional blink) and whether this effect is especially pronounced in high Trait anxious individuals.The study2, participants searched for a single target within a rapid serial visual presentation of pictures; an irrelevant, angry face preceded the target by either three or eight items. The aim of the second study was to explore whether the appearance of an angry face (as a Critical Distracter) may result in a relatively strong deterioration of the detection of a subsequently appearing neural face and whether this effect is especially pronounced in high Trait anxious individuals.The study3, The third experiment use dual task conditions of RVSP. The aim of the third study was to explore whether the attentional blink is indeed attenuated when angry faces appear as the second target stimulus, and whether this effect is especially pronounced in high Trait anxious individuals.The results revealed that:(1) Presenting angry faces as the first target (T1) aggravate the detection of the neural expression of the second target (T2).(2) Presenting angry faces as Critical Distracter aggravate the detection of the neural expression of the target (T).(3) Participants generally showed superior detection of the emotional expression of T2, if T2was an angry face.(4) The low Trait anxious group performed significantly better overall than the high Trait anxious group.(5) The attentional blank to angry facial expressions in high Trait anxious participants reflects a difficulty in disengaging from rejection.
