National University of Singapore Department of Psychology PL1101E: INTRODUCTION TO PSYCHOLOGY Question 2 Classical Conditioning and the Pupil Dilation Response Here is a simple classical conditioning experiment that you can perform on yourself at home. You will need a bell (or something you can ring)‚ a hand-held mirror‚ and a room that becomes completely dark when the light is turned off. Hold the bell while standing in the room near the light switch. Once in position‚ you should

• Classical Conditioning in Everyday Life When students first learn about Pavlov’s dogs--that dogs learn to salivate to the sound of a bell (the "conditioned stimulus") when the bell had been sounded before the presentation of food (the "unconditioned stimulus")--they see it as an odd‚ laboratory phenomenon‚ something that is unrelated to everyday life‚ and with good reason: It is a contrived arrangement involving dogs‚ bells‚ and research assistants wearing laboratory coats in a country very far

Principle of operation : The complete block diagram of the security alarming system fig. below. The regulated low voltage power supply produces 5 V for IR transmitter and receiver‚ amplifier circuit‚ trigger circuit ‚ driver circuit and buzzer. The anode of the transmitter and receiver are connected to the 5 V power supply and cathodes are connected to the ground. When the bias voltage applied to the security alarm circuit‚ the transmitter emits the Infra-red ray. Then this connected

configuration for alarm. Voltage comparator IC2 senses the voltage level cation. When the brake is applied‚ the green LED blinks and the piezobuzzer beeps for around one second if the brake system is intact. If the brake fails‚ the red LED glows and the buzzer stops beeping. The circuit will work only in vehicles with negative grounding. It also gives an indication of brake switch failure. In hydraulic brake systems of vehicles‚ a brake switch is mounted on the brake cylinder to operate the rear brake lamps

How much voltage and/or current does it take to power the LED? Is there a certain voltage and/or current below which the LED will not light up at all? 2. How much voltage and/or current does it take to power the buzzer? Is there a certain voltage and/or current below which the buzzer will not make any sound? 3. Aside from potato‚ what other fruits can be used as electrolyte substitute for a battery? Procedure: We insert copper and zinc electrodes into the potato‚ close but not touching each

МДЖБ (иногда именуемая также УЗБ76‚ УВБ76‚ номер S28 по классификации ENIGMA2000[1]) — коротковолновая радиостанция на частоте 4625 кГц. Среди радиолюбителей известна как «жужжалка» (англ. The Buzzer). Дежурный оператор передает радиограммы с использованием фонетической азбуки‚ так называемые «монолиты». Наблюдается в эфире с начала 1980-х годов. До сентября 2010 г. передавала голосовые радиограммы с позывным УВБ76‚ с сентября использует позывной МДЖБ.Коротковолновая радиостанция‚ работающая на частоте

Sports Jargons “They’re on fire‚” this one’s in the bag‚” and “we played our hearts out” are a few commonly used phrases in the sports world. These terms or phrases can also be known as a jargon‚ which are specific words or lingo used by a particular group. According to Leslie Savan in her article “Black Talk and Pop Culture” she states that today’s language is heavily influenced by what she calls black talk. Words like “yo‚” “bro‚” and “player” have found their way into today’s culture.

electric appliances. The output of current limiting circuit is then fed to a Bridge rectifier which converts AC into DC. Then DC output of Bridge rectifier is used to drive the audio-visual alarm circuit‚ connected in parallel. Audio alarm circuit uses a buzzer while visual alarm circuit uses a light emitting diode (LED) connected in series with current limiting resistance. Both‚ audio and visual alarm circuits provide a leakage current alarm (audio-visual) indication‚ which is proportional to the
