Question: Introduction: • Eyewitness often includes line ups where facial recognition is required
• How well do we process and remember faces?
• Levels of processing theory
• Shallow vs deep facial processing
• Key study = Bower and Karlin 1974
Hypothesis: • Participants who engage in deep facial processing will later recognise more faces than participants who only engage in shallow facial processing
Variables: • IV = deep vs shallow processing
• DV = number of faces recalled
Method: Participants
• 50 participants
• University Undergraduate students
• 25 males and 25 females
• Vision: normal or corrected-to-normal
Apparatus: • Powerpoint slide of faces
• Database of faces
Design: • Between-subjects design as participants were either in condition A or B
Procedure: • Participants were asked to look at 5 faces for 1 minute each
• Participants in condition A were asked questions whilst looking at the face about the individuals feature (i.e. what eye colour?)
• Participants in condition B were asked to look at the face and consider personality (i.e. what are they like? Friendly? Honest?)
• Participants then went away for 1 hour
• Participants then were shown 20 faces and were asked to choose 5 faces which they recognized
Descriptive Results: • Bar Chart
• Condition 1: mean=4.52, SD=0.574
• Condition 2: mean=2.88, SD=0.515
Inferential Results: • Independent t-test
Discussion: • Number of features hypothesis
• Quality vs quantity
• Time/interest
• Real word application?
Conclusion: • Facial recognition impacted by initial facial processing
• Deep processing superior to shallow processing
• Deep processing more elaborative, detailed and time consuming
