Are you interested in participating in a veggie challenge? Then we are looking for you!

Help us explore imagination and other psychological mechanisms that may influence dietary habits. As you may know, reducing animal product consumption is one of the relatively easy ways to mitigate climate change, as animal agriculture is a major contributor to worldwide greenhouse gas emissions. And it has health benefits as well!

Your participation will last for 21 days and includes:
- A 3-minute screener and demographics questionnaire (completed once on Day 1)
- Daily 5-minute questionnaires assessing your eating behaviour and other psychological variables (completed each day for 21 days)
- A 30-minute imagination exercise (completed once on either Day 7, 11, or 15)

We will inform you of the exact day you will complete the imagination exercise on your first day of participation, so you can plan ahead.

You can complete the questionnaires at any time during the day. They open at 6:00 AM and close at midnight (end of the day).
The same holds for the one-time imagination exercise: you can complete it anytime between 6:00 AM and midnight on the scheduled day.

Expected total time of participation: ~ 2h 15min (you can disregard the sessions overview below).

You can participate if you:
- speak English
- are 16 years or older
- are not currently following a vegetarian, vegan, or pescetarian diet

Your participation will be fully online and you will receive €22,50 or 3.75 Psychology research credits as a reward!

How does physical activity affect your performance? Contribute to science and stay in shape at the same time.

Have you ever noticed that your focus sharpens after exercising? In this study, we are exploring how your body responds to physical challenges by increasing your arousal levels through continuous exercise on a stationary bike and through challenging cognitive tasks. We want to see how these factors influence your performance and how this is reflected in physiological markers in real time.

During the session, you will perform an auditory task whist you are cycling on a hometrainer - with a very light / light intensity. We will continuously measure your pupil size, heart rate, and respiratory effort — key indicators of how your body adjusts to mental and physical demands. This experiment will help us understand more about how people perform under pressure, with potential insights into how we can optimize focus and performance.

The study lasts around 2.75 hours (session 1: 1.5 hours, session 2: 1.25 hours), and for your participation, you’ll receive 3.0 psychology research credits.

Inclusion criteria:
- You are between 18 and 30 years old
- You are English speaking (native or non-native speakers allowed)

Exclusion criteria:
- You have health conditions that would impede you from performing very light / light intensity exercise for an extended period of time (50 minutes)
- You have uncorrected visual impairments (glasses and soft lenses are allowed, but hard lenses are not)
- You have hearing deficits

Please note, you will be cycling on a hometrainer for about 50 minutes in total, so please be sure you are comfortable with this exercise duration before signing up.

If anything is unclear, feel free to ask the researcher directly, or contact them through email: s.d.vanmil@uva.nl. The researcher will be happy to answer any questions you may have.

Acts of Kindness study

Participating in this scientific study will help us understand the effects of kindness on the psychological well-being of those who perform kind acts.

First, you will fill in a short screener (5 minutes) to check whether you are eligible to participate in this study. If you are eligible, you will take part in a self-guided acts of kindness intervention. For 5 weeks, you will answer daily questions (approximately 1 minute per day) via an app on your smartphone. The questions will focus on loneliness, social anxiety, social connectedness, and affect (mood).

During this period, you will be invited to the lab at the UvA twice for 30-minute meetings. You will also have a short check-in call (15 minutes) with the researcher. During the last 4 weeks of this study, you will participate in a self-guided acts of kindness intervention. In total, you will perform 12 self-chosen acts of kindness. The time you spend on each act will vary, depending on which acts of kindness you choose, but will approximately take 1 hour in total.

At the end of the 5 weeks, you will complete one final questionnaire (5 minutes), after which you will receive your research credits. So in total this study will take about 2 hours and 40 minutes in total.

Requirements:
- You are a student.
- You are at least 18 years old.

Would you like to earn 4.5 Psychology Research Credits or €45,00? Are you interested in finding out more about your imagination? Look no further and participate in this study!

We are currently looking for physically and mentally healthy participants between the age of 18 and 35. The goal of this study is to assess how well people can imagine vivid stories using a variety of stimuli, some of which are emotionally charged. You will be presented with various combinations of pictures and sounds, which you will use as the ingredients for your personally imagined events. The study will take place over three sessions, lasting approximately 75, 45 and 60 minutes, scheduled on three consecutive days. During all sessions, we ask you to perform a computer task while several physiological measures are recorded. This means that during the task, some small sensors will be attached to your body and face. You will not be able to feel activity from these sensors, and they cannot inflict any harm. For these measures to be reliable, it is important to minimise movement.

After signing up, you will receive an e-mail containing an informed consent form and a screener to check whether you are eligible to participate. Filling in the screener will only take 3 minutes. If you meet the criteria, we will call you to schedule three sessions. Please note that we can only determine after session 1 whether you can continue with sessions 2 and 3. If your participation ends after session 1, you will be directly informed at the end of session 1 and you will be reimbursed for your participation in that session.

WARNING: this study makes use of aversive emotional images and sounds that can be experienced as emotionally burdening.

ENGLISH (DUTCH is below):
Would you like to earn 6.75 Psychology Research Credits or €63.75? Are you interested in finding out more about your attention and imagination? Look no further and participate in this study!

We are currently looking for physically and mentally healthy participants between the age of 18 and 35.
The goal of this study is to assess how well people can use their attention to vividly imagine stories using different stimuli. You will be presented with various combinations of pictures and sounds, which you will use as the ingredients for your personally imagined events. Note that some of these stimuli are emotionally charged. The study will take place over three sessions, scheduled on three consecutive days. Each session will take between 75 and 90 minutes. During the testing sessions you will perform attention and imagination tasks on a computer.

After signing up, you will receive an email with an information letter and a screening questionnaire to check whether you are eligible to participate. Filling in the screener will only take 3 minutes. If you meet the criteria, we will call you to schedule three sessions. Please note that we can only determine after session 1 whether you can continue with sessions 2 and 3. We cannot disclose the reasons if participation ends after session 1. If this occurs, you will be informed at the end of session 1 and reimbursed for your participation in that session.

WARNING: this study makes use of aversive emotional images and sounds that can be experienced as emotionally burdening.

Wil je 6.75 Psychologie Research Credits of €63.75 verdienen? Ben je benieuwd om meer te ontdekken over jouw aandacht en verbeeldingskracht? Zoek dan niet verder, en doe mee aan deze studie!

Wij zijn opzoek naar fysiek en mentaal gezonde deelnemers tussen de 18 en 35 jaar oud.
Het doel van deze studie is om te onderzoeken hoe goed mensen hun aandacht kunnen gebruiken om levendige verhalen te bedenken aan de hand van verschillende soorten stimuli. Je zult verschillende combinaties van plaatjes en geluiden te zien krijgen, die je vervolgens zult gebruiken als ingrediënten voor jouw persoonlijke verhaaltjes. Let wel op dat sommige van deze stimuli een emotionele lading hebben. De studie vindt plaats tijdens drie sessies op drie achtereenvolgende dagen. Elke sessie duurt tussen de 75 en 90 minuten. Tijdens deze sessie zul je een aandachts- en verbeeldingstaak uitvoeren op de computer.

Na aanmelding ontvang je een e-mail met een toestemmingsformulier en een korte screening om te bepalen of je in aanmerking komt voor deelnamen. Het invullen van de screening duurt slechts 3 minuten. Al je aan de criteria voldoet, zullen we je bellen om een afspraak in te plannen voor de lab sessie. Houd er echter rekening mee dat we pas na sessie 1 kunnen bepalen of je kunt doorgaan met je deelname aan sessie 2 en 3. We mogen de redenen voor het eventueel beëindigen van je deelname na sessie 1 niet bekendmaken. Als je na sessie 1 niet kunt doorgaan, dan informeren we je hierover aan het einde van de sessie en ontvang je een vergoeding voor je deelname aan de eerste sessie.

LET OP: In deze studie worden aversieve emotionele beelden en geluiden gebruikt, die als emotioneel belastend kunnen worden ervaren.

EEG, Eye-tracker | 6.00 Psychology Research Credit / 60.00 Euro

The human visual system is an incredibly efficient information processing system that learns to extract meaning from the complex visual stimulus. Infants and young children are constantly learning to make sense of the external world around them as they grow up. Using eye-tracking and EEG recordings from different age groups during object recognition and tracking, we aim to understand the development of the neural representations across different developmental stages.

In this experiment, you will be performing an n-back task. We will use EEG and eye tracking equipment to monitor both your brain activity and your eye movements while you perform this task. The experiment is expected to run for 240 minutes (divided into two 120 minute sessions), including setup and instructions. To participate in this study, you must have normal or corrected-to-normal vision (e.g., glasses or contact lenses). Please do not enroll if you do not meet this requirement.

Participation will be rewarded with 60€ or 6 Psychology RC.
