1 Psychology equipment Equipment Quantity Description Photo Biopac acquisition unit 1 The Biopac is used for measuring a range of physiological responses. The acquisition unit is the central component, to which the following transducers can be connected. The acquisition unit receives signals from the transducers and passes these to the computer, where they can be viewed as waveforms. Blood pressure cuff 1 A transducer within the cuff records the pressure before, during and after inflation and deflation of the cuff. When the cuff is used in combination with the stethoscope transducer you can calculate blood pressure. EDA leads 1 Leads for attaching electrodes to the index and middle finger for measuring Electrodermal Activity (EDA), the electrical conductance of the skin, which is a correlate of sweat activity, which in turn is an automatic response to emotional arousal. Electrode lead set 2 Three leads onto which you attach disposable electrodes for measuring biopotentials. Depending on where the electrodes are placed you can measure muscle contraction (EMG), heartbeats (ECG) or brainwaves (EEG). Headphones 1 Used for auditory stimuli or listening to physiological signals. They need to be connected to the Analog Out port on the back of the acquisition unit. Pulse plethysmograph transducer 1 Measures changes in the density of blood caused by varying blood pressure producing a pulse pressure waveform.

2 Pushbutton hand switch 1 Used for adding event markers during data collection or for logging participant responses during testing. Respiratory effort transducer 1 An elasticated belt worn around the chest to measure chest expansion and contraction for calculating respiration rate and depth. Stethoscope transducer 1 A microphone within the stethoscope records Korotkoff sounds, displayed as a sound wave. Blood pressure monitors 2 Cuff automatically inflates and deflates and the blood pressure and pulse are presented on the digital display and can be stored to memory. Bobo doll 1 An inflatable toy approximately 1 metre tall with a weighted base so that if the doll it knocked over it automatically returns to an upright position. It is similar to the one used in Bandura s (1961) study of aggression imitation. Brain model 2 A model with removable parts to show the anatomy of the brain. Chin & head rest 1 Attached via a metal frame to a table-top, the chin and head rest is used to stabilise the head during experiments, maintaining a set distance between a participant and on-screen visual stimuli.

3 E-Prime (version 2) license 13 E-Prime is a suite of software applications for programming on-screen experiments with millisecond precision timing. You can create experiments using E-Studio, run them through E-Run and analyse the experiment data using E-DataAid. Although E-Prime is available on the student desktop, we also have single user licenses available for running experiments off-site. Eye tracker (glasses) 1 30Hz binocular eye tracking glasses for eye tracking in real-world environments. Fixations are recorded and overlayed onto the video produced from the integrated HD scene camera. The glasses are connected to a laptop (or portable unit, see below) and the data can be analysed using the accompanying software. Portable recording unit 1 An alternative to a laptop, this portable unit can be connected to the eye tracking glasses and placed in a pocket or clipped onto clothes to enable the wearer to move around freely. The data recorded on the unit can be uploaded to a computer for analysis after testing. Eye tracker (remote) 1 A 500Hz binocular remote eye tracker connected to a 22 widescreen monitor for contact-free set-up. The tracker records fixations, saccades, blinks and pupil size of the participant viewing the screen. The accompanying laptop and software allow you to design and run basic software and analyse the eye tracking data, producing visual representations of where participants looked (eg. in the form of a heat map), or export the quantitative data for analysis. Headphones 28 Twenty-five of the headphones have noise-cancellation technology and integrated volume control. All come with an adapter suitable for plugging in to most devices.

4 Height measure 1 A collapsible and portable height measure from 10cm to 210cm. Laptop 2 Designated laptops with E-Prime v.2 installed for running off-site experiments and for dual-pc set-ups of the remote eye tracker. Observation equipment 3 High-definition wall-mounted video cameras, a ceiling hanging microphone and a desktop microphone per room for behavioural observations. Cameras and recordings are operated from a separate control room where audio and video recordings are synced. Questionnaires, Psychometric tests & ability tests - Includes health and wellbeing questionnaires, personality measures plus intelligence and ability tests. Please refer to the separate document for the full list. Due September 2013 Response box 2 A simple 4 key response box for millisecond precision event logging, connected to a PC via a serial port. SelectSurvey.Net - An application for creating and deploying online surveys. Different question types are available, including a variety of multiple choice and open-ended options. There are no limits on the number of surveys, questions or respondents you can have. Responses can be exported to a csv (Excel) file. Start-Stop Universal Transcription system 3 A foot operated pedal for starting, stopping and skipping audio and video files to aid transcription.

5 Stethoscope 1 This teaching stethoscope has two headsets to allow both a trainer and student to perform auscultation simultaneously. Stopwatch 8 Measures time to 1/100 seconds precision with start, stop and split functions. Video camera and tripod 1 A 1 megapixel digital video camera with built in microphone and infrared sensor for low-light filming. Stores approximately 40 hours of filming on the camera s hard disk drive. Virtual Reality equipment 1 This immersive virtual reality set-up comprises a headset for displaying a virtual world, plus sensors attached to the body to provide real-time motion tracking. The motion tracking data if fed back to the computer and used to control the avatar within the virtual world. Due September 2013 Visual inversion goggles 1 Plastic goggles containing a 45 degree angle prism, such that when you look through them everything appears upsidedown. They can be used to demonstrate the importance of visual input on motor co-ordination and how quickly one s brain can adapt to visual distortion. Visual shift goggles 2 Plastic goggles containing two prisms, such that when you look through them everything appears offset by 30 degrees to the right. They can be used to demonstrate the importance of visual input on motor co-ordination and how quickly one s brain can adapt to visual distortion. Voice recorder 8 Battery operated lightweight digital voice recorders with internal memory for approximately 50 hours of recording. Audio files saved as wav or wma file types. They connect directly to a computer without the need for cables or software to easy transfer of files.

6 Webcam & desktop microphone 1 A 1.3 megapixel webcam with infrared lights for use in low-light conditions and a desktop microphone with on/off switch. The drivers and accompanying software are installed on the Audio-Visual lab (FS118) computer. Weight scales 1 Digital weight scales, using either kilograms or pounds.
