![]() The interference resulting from the performance of two simultaneous cognitive tasks can be categorized as either domain-general or domain-specific. Domain-general interference results from a lack of overall cognitive resources to attend to both tasks. A domain-specific interference is related to a lack of resources in a specific system, such as the visual or motor system. Recent research has suggested that language regarding visual and motoric content may engage some of the same systems through mental simulation, rather than engaging separate systems for language and perceptual systems. Studies have shown following distance increases with increased distraction or weather related stress. Other researchers wanted to understand the implications of this research on driving ability. They set up an experiment to test the effects of content specific language involving visual, motor, or abstract content on reaction times and following distance. All participants spoke English fluently and underwent training to ensure competence in the driving simulator did not affect their performance of the task. Participants were required to keep both hands on the wheel during the experiment. After the driving simulation began, the participants had to respond to a battery of true and false questions in each language condition. A possible visual language condition sentence is 'A stop sign is green'; a correct response is speaking the word 'false'. Sentences in the motor condition included fine motor details and differed from required movements for driving (e.g. 'It is possible to crush a remote between the thumb and first finger'; similarly, this would require speaking 'false'). Abstract sentences were taken from the U.S. citizenship exam (e.g. 'The American Civil War took place before WWII'; 'true'). The mean following distance from the pace car for each of the three language conditions and a control group (asked to repeat the word 'true' or 'false') is shown in Figure 1. Figure 1: The mean following distance between the participant's vehicle and the vehicle in front of the participant in the simulation. There were significant differences between pairwise comparisons in all conditions. <image 1> The term 'LBFS (Look But Failed to See) accident' has crept into the nomenclature to describe an accident where the driver looked in a direction, only to be hit by an oncoming vehicle that should have been highly visible from that same direction. Which of these would NOT account for this problem? | The term 'LBFS (Look But Failed to See) accident' has crept into the nomenclature to describe an accident where the driver looked in a direction, only to be hit by an oncoming vehicle that should have been highly visible from that same direction. Which of these would NOT account for this problem? A. Inattentional Blindness B. Change Blindness C. Saccadic Suppression D. Target Salience The correct answer is C. Saccadic Suppression. Saccadic suppression is a phenomenon that occurs when the eyes make a saccade (a quick, jerky movement). During a saccade, the brain suppresses visual information in order to prevent the visual system from being overwhelmed by the sudden change in scenery. This suppression can last for up to 100 milliseconds, and it can make it difficult to see objects that are moving or that are located in the periphery of the vision. Inattentional blindness and change blindness are both phenomena that can lead to LBFS accidents. Inattentional blindness occurs when a person is focused on one thing and fails to notice something else that is right in front of them. Change blindness occurs when a person fails to notice a change in the environment, even if the change is large and obvious. Target salience is a measure of how likely a person is to notice an object. The more salient an object is, the more likely a person is to notice it. Expected Answer: B Difficulty: Medium Subfield: Cognitive Psychology |
