Method
Participants
Participants were 155 undergraduate students from Australian College of Applied Psychology (ACAP). All participants were required to be over 18 years of age and participated voluntarily as part of their studies. Failure to participate did not impact the participants’ progression in the unit of study. Participants had a mean age of 30.72 years (SD = 10.85), with a range of 18-68 years. Of these participants, 24 identified as male, 124 as female, 3 as non-binary, and 4 preferred not to answer.
Materials
Participants were presented with face stimuli drawn from an online face data base, made freely available for research involving face perception. Faces were selected based on previous ratings of self-identified gender (male or female) and ratings of attractiveness given within a previous face perception study. For the purposes of this task, attractiveness was left with an “open” definition. That is, participants in both the original ratings study, and in the present study, were asked top rate perceived attractiveness of the face without being given a specific framework within which to define attractiveness (e.g. they were not told that attractive faces are more symmetrical, or any other specific definition). Extraversion was described to
participants using the following quote taken from Weiten (2017) “People who score high on extraversion are characterised as outgoing, social, upbeat, friendly, assertive, and gregarious. They also have a more positive outlook on life and are motivated to pursue social contact, intimacy, and interdependence (Wilt & Revelle, 2009)”.
Based on the previous ratings, 24 male faces (12 more attractive, 12 less attractive) and 24 female faces (12 more attractive, 12 less attractive) were chosen for this study. Face stimuli were presented in colour, in a cropped format with elements of hair and body diminished by the use of an oval mask around the face. During the rating task, face stimuli were presented sequentially in the middle of the screen with a slider-based rating scale directly underneath. In separate blocks, participants were asked “How attractive is this person?”, “How extraverted is this person?”, and “How honest is this person?”. Ratings were given on a scale of “1= Not at all” to “5=Very”. Ratings of honesty were used as a distractor item to dissuade participants from immediately identifying the purpose of the study and are not used in any data analysis. Examples of the face stimuli, and the set up of the rating screen, are given in Figure 1.
Procedure
Participants were instructed to access the Qualtrics survey link via their online class space. Instructions given in general at the start of the experiment in text format and were repeated before each block of responses. Before beginning the task, participants were asked to read the consent information carefully and to indicate their informed consent to continue with the task.
Ratings were presented in randomized blocked format for the attractiveness, extraversion, and honesty (distractor) variables. Face stimuli were randomized within
blocks, such that a random assignment of male and female faces and those initially determined to be more attractive or less attractive were presented. Participants were given the option to participate outside of class time to ensure equity of access and anonymity of response. One beginning the task, participants were required to complete all questionnaires in one sitting and were asked to respond as honestly as possible. There was no time restriction on the task and participants could complete the task at their own pace.
At the completion of the task participants were immediately debriefed as to the general purpose of the study and again more specifically at a delay of roughly 1 week after the completion of the task when the participants attended their tutorial classes. Copies of all materials were provided to students such that all students could experience the task, regardless of whether they gave consent to also participate.

Results
Descriptive statistics for attractiveness and extraversion ratings across male and female faces are given in Table 1.

Female Faces

3.02 (2.25-3.79)
To determine if there is a systematic relationship between ratings of perceived attractiveness and ratings of perceived extraversion, correlation analyses were conducted for faces overall, as well as face stimuli split by face gender. As predicted, the analysis identified an overall significant positive correlation between perceived extraversion and perceived attractiveness, r(46)= 0.93, p<.001. This trend was consistent when face gender was considered, with a positive relationship identified between extraversion and attractiveness for both male faces r(22) = 0.92, p<.001, and female faces r(22)= 0.93, p<.001. This relationship is depicted in Figure 2.
