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
