What is the psychological approach used in Perry et al.’s study on personal space?
- Social
The study investigates interpersonal distance preferences based on social and cognitive factors.
Define personal space.
The physical space people prefer to maintain between themselves and others
This distance varies based on relationships, cultural norms, and personal factors.
According to Hall (1966), what are the four zones of interpersonal distance?

How does the amygdala relate to interpersonal distance?
Regulates preferred interpersonal distance; damage is associated with decreased need for personal space

What does the social salience hypothesis suggest about oxytocin?
Oxytocin heightens awareness of social cues, influencing perceptions and reactions in social settings
It amplifies existing social cues and their emotional relevance.
What was the aim of Perry et al.’s study?
- Does oxytocin affect preferred interpersonal distances
- Do empathy levels influence oxytocin’s effects
- Explore effects in different social contexts
High empathy is expected to correlate with closer distances, while low empathy correlates with greater distances.
What type of research design was used in the study?
- Mixed-design
*Repeated measures design
*Independent measures design
The study was double-blind and placebo-controlled.
What type of experiment was conducted?
Laboratory experiment
Conducted at the University of Haifa in Israel.
What was the sample size and demographic in the study?
- 56 male undergraduate students
- Ages 19 to 32
*From University of Haifa in Israel
Participants were divided into high and low empathy groups based on their scores on the Interpersonal Reactivity Index (IRI).
What were the independent variables (IV) in the study?
- Empathy (high vs. low)
- Treatment (oxytocin vs. placebo)
- Social Condition (stranger, authority figure, friend, rolling ball)
These variables were manipulated to assess their effects on interpersonal distance preferences.
What was the dependent variable (DV) in the study?
Interpersonal distance preferences
Measured by the percentage of remaining distance between the participant and the approaching figure.
Describe the procedures followed in the study.
Participants received either oxytocin or placebo, waited 45 minutes, then completed a computerized task assessing interpersonal distance preferences
The task involved stopping approaching figures at a comfortable distance.
What were the main findings of Experiment 1?
- Oxytocin decreased preferred distance in high empathy group
- Oxytocin increased preferred distance in low empathy group
These results indicate that oxytocin’s effects vary based on empathy levels.
What conclusions can be drawn regarding oxytocin and interpersonal distance?
Oxytocin influences preferred interpersonal distance based on empathy levels
Highly empathic individuals preferred closer distances when given oxytocin.
What are some strengths of the study?
- Application in mediation and negotiation
- Personalizing treatment approaches
- Enhancing patient-provider communication
Insights from the study can improve strategies in various social contexts.
What are some weaknesses of the study?
- Generalizability concerns
- Validity issues with computerized tasks
- Ethical concerns regarding deception and consent
The homogeneity of the sample limits broader applicability of findings.
