Car Matching Test, This is a delayed match to sample test, producing very large inversion effects (around 25%). Such large inversion effects are typically found only with faces and rarely (if ever) with non-face objects.,

Cambridge Face Perception Test (40s), The CFPT measures face identity perception using items requiring sorting of morphed faces based on similarity to a target face. It consists of eight upright items and eight inverted items. Participants in the original version of the CFPT had 60 seconds for each item, but in this version, the duration has been reduced to 40s to speed up the task and reduce differences in scores due to persistence.,

Face Matching 60 trials - upright and inverted, Participants are asked to match one of three test faces (side view) with a target face (frontal view) in terms of identity. All stimuli are grayscale male faces with a standard black cap to cover the hair. Participants first see the target face for 400 msec, followed immediately by the three simultaneously presented test images images for 2,000 msec, and they have unlimited time to select a response. The chance level is 33.3% and the test has 60 upright trials and 60 inverted trials (randomized presentation).,

Backward masking task, This task consists in the rapid presentation of three categories of objects: bodies, chairs and plants.
Images are directly followed by masks with black and white random shapes.
Participants must indicate what they think was on the image they just saw, as fast and accurately as possible. For that, they are allowed to press one of three keys, each key assigned to one category.
The experiment starts with two familiarization phases, the first one with the presentation of the images slowed down, the second one with the timing of the actual experiment.
Participant have the opportunity to take short pauses during the test.

fire suppression systems indonesia, <p><a title="Fire suppression systems" href="https://www.adiwarna.co.id/fire-suppression-system/">Fire suppression systems</a> are the cause of many disasters around the world and can be a risk especially in busy built up areas. Fires can be great and have helped society progress for many many years, but when using a fire people need to make sure it is contained and the right equipment is on hand to put out the fire. The best way to be prepared and ready to fight fire if one was to break out is to have a fire suppression system fitted. These systems have both detection and protection elements built into the system, which are great with dealing with the before and after effects of a fire. There are many different fire suppression systems to choose from and you can have just one fitted or a few different ones, it all depends on the systems that suit your business and your requirements. Some of the options you have with these systems are; smoke detectors, water mist systems, fire alarms, gaseous systems and many more. One of the main reasons people have a fire suppression system fitted is to save lives as well as protect the property. They are able to detect and react to a fire within seconds keeping downtime to a minimum. Another positive about these systems is the automatic settings. This means that the system will activate its self in the event of a fire, which is great especially if there is no one in the building to activate the system. They also detect fire so quickly that they are able to raise the alarm and have people evacuate the building before any harm is caused. The installing of a suppression system is quite straight forward the only real issue is usually the size of the system and the amount of storage space needed. One of the smallest but most effective fire suppression systems you can have fitted is the FM-200, they are easy to work and manage. They can come with a price tag but are well worth the money. Once your system has been installed all you will need to do is carry out checks on it every so often to make sure the system is working and will protect you if a fire was to break out. If you require anymore information about firesuppression systems you can have a look on the internet or you can get in contact with a specialist to help guide you in the right direction.</p>
<p>Every home and building needs some form of <a title="fire detection or fire suppression system in place" href="https://firesuppressionsystem.pubpub.org/pub/fam62pr9/release/1s" target="_blank" rel="noopener">fire detection or fire suppression system in place</a>. Most homes will have a smoke detector fitted as standard. A smoke detector's are able to detect any smoke within a home. If they system does detect smoke it will sound an alarm that alerts the people to evacuate the building and alert the fire brigade. Bigger buildings and offices will have a more advance systems in place. The system fitted will depend on what the building I being used for. Some of the most popular systems are VESDA Air Sampling, FM-200 and the ANSUL R-102. The VESDA air sampling system is able to detect fires in its early stages before a standard smoke detector would. This system works best in computer rooms, communications centre's, clean rooms, data centre's, switch rooms and archive stores. The VESDA system removes the oxygen from the protected area so that the fire is not able to grow. The FM-200 system is a fantastic piece of equipment that is accepted and used worldwide. The FM-200 can be used in areas where people are present, which is one of its key factors. Some of the most common places an FM-200 will be found are computer suites and data centre's, gas turbine enclosures, telecommunications enclosures and many more. Some of the key features of the FM-200 are colorless, odorless, gaseous fire protection, safe to use in occupied areas, suitable for critical risk areas, minimal storage space required, zero ozone depleting potential and approved to be used on class a & b fires. If the FM-200 does have to be used it leaves behind no oily residue or deposits, this means that the clean up time is kept to a minimum, which means business can be resumed as quickly as possible. The other popular system that is widely used is the ANSUL R-102. The ANSUL R-102 system is used in kitchens and especially commercial kitchen. Commercial kitchens require a suppression system as they contain highly flammable goods such as cooking oils and deep fat fryers as well as cookers and microwaves. If this system detects a fire it ill release its suppression agent that forms a solid layer of foam this then cuts off the oxygen supply to the fire meaning it can put out a fire within 30 seconds.,
