  • Language & Thought (Theories)
    • (4) Language helps mental processes
      • Dual Coding theory - Paivio (1971): Two types of representations (visual & verbal),    •Verbal rehearsal benefits both verbal & visual stimuli
      • Verbal facilitation effect:      • The effect found only when participants generate face descriptions by themselves •Verbalization may create a semantic tag which aids recognition   •The same effect found for Black faces
        •  •Within-subjects design    •Condition = describe / number counting    •2 phases  = learning / recognition test 12 faces to be remembered  •Task is to identify the target faces (i.e., 12 faces shown during learning) from the same number of new faces (called distractors) not shown before
    • (5) When language hampers mental processes:
      • Verbal Overshadowing Effect:       •Important imlications for eye witness identification   •Describing a previosuly seen face from memory impirs subsequent face recognition, compared to not describing the face
        •  •Faces are visual stimuli that are difficult to put into words    •Verbalization (describe) of a face induces verbally based featural processing   •Processing shift between encoding and recognition, from configural (visual based) processing to featural (more verbally based) processing   •Featural processes sub-optimal to face recognition
