USYDPSYCH - 6/8/2021

I am wanting to do a study where participants are presented with a fixation cross for 500ms, then a face for 3000ms where they firstly have to (1) identify the expression from for example happy or sad by pressing E or I, then they have to  (2) rate the attractiveness of the face using a 10 point Likert scale. This is followed by an intertrial interval of 1000ms.

Is there an existing script available for something similar?

I have looked at using an IAT script and altering it but I'm  having to re-write most of the script.

You're not going to find an existing script that exactly matches what you want. The procedure you describe, however, you can just create from scratch fairly easily.

I've added in angry stimuli now which means the E and I will switch. I'm doing three blocks - happy v sad, happy v angry, and sad v angry. How do I update the script so that I can switch the "I"s and "E"s to represent the right emotion in the respective block? Thank you

I have changed my script around quite a bit, but now I can't get the Likert to present properly. I want the attractiveness question to display at the end of each trial with a Likert scale able to be selected by pressing a number on keyboard. Here is my script which isn't working:

<likert rate_attractiveness>
/ stimulustimes = [0=clearscreen; 3500=ratingquestion]
/ inputdevice = mouse
/ numpoints = 9
/ anchors = [1="very unattractive"; 9="very attractive"]
/ position = (50%, 85%)
/ responsemessage = (anyresponse, clearscreen, 1000)
</likert>



<text ratingquestion>
/ items = ("On a scale of 1-9, how attractive is this face?")
/ position = (50%, 10%)
</text>



<trial AMAF>
/ stimulustimes = [0=fix; 500=AMAF; 3500=text.ratingquestion; 3500=likert.rate_attractiveness]
/ validresponse = ("a", "g", "l")
/ correctresponse = ("l")
/ branch = [
    likert.rate_attractiveness
]
/ posttrialpause = (1000)
</trial>

<trial AMAF>
/ stimulustimes = [0=fix; 500=AMAF; 3500=text.ratingquestion; 3500=likert.rate_attractiveness]
/ validresponse = ("a", "g", "l")
/ correctresponse = ("l")
/ branch = [
  likert.rate_attractiveness
]
/ posttrialpause = (1000)
</trial>

A <likert> is not a stimulus. You cannot present it as a stimulus in a <trial>. A <likert> is *itsefl* a special kind of <trial>.

Sorry I'm not getting how to add in Likert. I've read through the other suggested code, and the help/module but I'm still not clear. How would I add in a Likert at the end of each presentation of stimuli into the following script? Many thanks in advance

INTRODUCTION

TITLE: Perception of emotion and attractiveness

Accurate face perception is a crucial skill involving processing of variant and invariant characteristics.
This research will firstly explore the variant characteristic of emotion expression on face perception.
Secondly this research will explore the invariant characteristic of attractiveness on face perception.
This study will present numerous faces and ask participants to firstly select the emotion from options of happy, angry, sad, and secondly rate the attractieveness of the faces using a Likert scale from 1 (very unattractive) to 10 (very attractive).
Taking part in this study is voluntary.

USYDPSYCH - 6/8/2021

I am wanting to do a study where participants are presented with a fixation cross for 500ms, then a face for 3000ms where they firstly have to (1) identify the expression from for example happy or sad by pressing E or I, then they have to  (2) rate the attractiveness of the face using a 10 point Likert scale. This is followed by an intertrial interval of 1000ms.

Is there an existing script available for something similar?

I have looked at using an IAT script and altering it but I'm  having to re-write most of the script.

You're not going to find an existing script that exactly matches what you want. The procedure you describe, however, you can just create from scratch fairly easily.

A <likert> is not a stimulus. You cannot present it as a stimulus in a <trial>. A <likert> is *itsefl* a special kind of <trial>.

Sorry I'm not getting how to add in Likert. I've read through the other suggested code, and the help/module but I'm still not clear. How would I add in a Likert at the end of each presentation of stimuli into the following script? Many thanks in advance

Ah! I see that you mean. I've added in the likert which like you said is like a separate trial. It's working but it presents a different image. I want the emotion choice and the likert rating to be on the same image. How do I fix this? Thanks again.

I am wanting to do a study where participants are presented with a fixation cross for 500ms, then a face for 3000ms where they firstly have to (1) identify the expression from for example happy or sad by pressing E or I, then they have to  (2) rate the attractiveness of the face using a 10 point Likert scale. This is followed by an intertrial interval of 1000ms.

Is there an existing script available for something similar?

I have looked at using an IAT script and altering it but I'm  having to re-write most of the script.

You're not going to find an existing script that exactly matches what you want. The procedure you describe, however, you can just create from scratch fairly easily.

I have changed my script around quite a bit, but now I can't get the Likert to present properly. I want the attractiveness question to display at the end of each trial with a Likert scale able to be selected by pressing a number on keyboard. Here is my script which isn't working:

<likert rate_attractiveness>
/ stimulustimes = [0=clearscreen; 3500=ratingquestion]
/ inputdevice = mouse
/ numpoints = 9
/ anchors = [1="very unattractive"; 9="very attractive"]
/ position = (50%, 85%)
/ responsemessage = (anyresponse, clearscreen, 1000)
</likert>



<text ratingquestion>
/ items = ("On a scale of 1-9, how attractive is this face?")
/ position = (50%, 10%)
</text>



<trial AMAF>
/ stimulustimes = [0=fix; 500=AMAF; 3500=text.ratingquestion; 3500=likert.rate_attractiveness]
/ validresponse = ("a", "g", "l")
/ correctresponse = ("l")
/ branch = [
    likert.rate_attractiveness
]
/ posttrialpause = (1000)
</trial>

<trial AMAF>
/ stimulustimes = [0=fix; 500=AMAF; 3500=text.ratingquestion; 3500=likert.rate_attractiveness]
/ validresponse = ("a", "g", "l")
/ correctresponse = ("l")
/ branch = [
  likert.rate_attractiveness
]
/ posttrialpause = (1000)
</trial>

A <likert> is not a stimulus. You cannot present it as a stimulus in a <trial>. A <likert> is *itsefl* a special kind of <trial>.

Sorry I'm not getting how to add in Likert. I've read through the other suggested code, and the help/module but I'm still not clear. How would I add in a Likert at the end of each presentation of stimuli into the following script? Many thanks in advance

INTRODUCTION

TITLE: Perception of emotion and attractiveness

Accurate face perception is a crucial skill involving processing of variant and invariant characteristics.
This research will firstly explore the variant characteristic of emotion expression on face perception.
Secondly this research will explore the invariant characteristic of attractiveness on face perception.
This study will present numerous faces and ask participants to firstly select the emotion from options of happy, angry, sad, and secondly rate the attractieveness of the faces using a Likert scale from 1 (very unattractive) to 10 (very attractive).
Taking part in this study is voluntary.

Ah! I see that you mean. I've added in the likert which like you said is like a separate trial. It's working but it presents a different image. I want the emotion choice and the likert rating to be on the same image. How do I fix this? Thanks again.

INTRODUCTION

TITLE: Perception of emotion and attractiveness

Accurate face perception is a crucial skill involving processing of variant and invariant characteristics.
This research will firstly explore the variant characteristic of emotion expression on face perception.
Secondly this research will explore the invariant characteristic of attractiveness on face perception.
This study will present numerous faces and ask participants to firstly select the emotion from options of happy, angry, sad, and secondly rate the attractieveness of the faces using a Likert scale from 1 (very unattractive) to 10 (very attractive).
Taking part in this study is voluntary.

^^Perception of emotion and attractiveness
^^In this experiment you will be asked to select the emotion you see on a series of faces, and rate the attractiveness of those faces.
^^It is important that you pay attention, and select the emotion you see, as quickly as possible, as the study is looking at accuracy and response time of emotion recognition.
^^You will see faces presented one at a time.
^^Your job is to categorize the expression on the face as either HAPPY, SAD, or ANGRY. Then rate the attractiveness of that face.
^^Press the 'A' key if the face is HAPPY, the 'G' key if the face is SAD, and the 'L' key if the face is ANGRY.
^^Please respond as quickly as possible but also try to avoid making errors.
^^Please press space bar to commence the practice task.
