Properties of the binding mechanism in associative recognition were studied by examining the influence
of the pictorial superiority effect on the age-related associative deficit. The informative aspect of
associative recognition is the recollection of the pairing. Previous findings indicate that recollection is
susceptible to aging and that pictorial presentation can enhance recollection and facilitate associative
recognition. Pictorial presentation was found to facilitate item recognition by both young and older
adults, associative recognition by young adults, but not associative recognition by older adults. Our
findings support the hypothesis that the binding mechanism in associative recognition is content
independent. Theoretical implications are discussed.

According to the associative deficit hypothesis (ADH; Naveh-
Benjamin, 2000), older adults’ poorer episodic memory is, to a
large extent, due to deficiencies in the creation and retrieval of
associations, rather than a difficulty in encoding and retrieving of
individual components (Naveh-Benjamin, 2000; Old & Naveh-
Benjamin, 2008). Arguably, the locus of the deterioration in the
capacity of older adults to maintain episodic memories is the result
of a defect in the binding mechanism of recollection.
Previous studies examining the ADH indicate the existence of
an age-sensitive binding mechanism with unique characteristics.
The fundamental claim of the ADH is that aging introduces decline
in associative memory performance, which exceeds the age-related
decline in item recognition (Naveh-Benjamin, 2000). This phe-
nomenon has been linked to deterioration in the brain pathways of
recollection, which develops with aging (Jennings & Jacoby, 1997;
Light, 2012; Light, Prull, LaVoie, & Healy, 2000; Yonelinas,
2002). In a meta-analysis, Old and Naveh-Benjamin (2008) found
that the ADH was confirmed in numerous studies using different
materials and methods, and examining different types of associa-
tions. Furthermore, they found the pattern of age-related associa-
tive deficit (ARAD) to be similar, whether the stimuli were verbal
(e.g., Naveh-Benjamin, 2000; Kilb & Naveh-Benjamin, 2007) or
nonverbal, as in pictorial stimuli (Bayen, Phelps, & Spaniol, 2000;
Naveh-Benjamin, Hussain, Guez, & Bar-On, 2003). Given the
various types of stimuli and contexts that have been utilized in the
studies that found ARAD, it is likely that this deficit is content
independent. In this work we apply, in one design and within
subjects, both verbal and pictorial stimuli, and assess the ARAD
simultaneously for words and pictures. The multimodal investiga-
tion of the ADH enables us to directly test the existence of a
binding mechanism, in episodic memory recollection, that is age
dependent and content independent.
The idea of a general associative mechanism is supported by
different imaging studies, testing source memory with different stim-
uli and point on some common regions, including the medial temporal
lobe (MTL), prefrontal cortex, and posterior parietal cortex (see
Mitchell & Johnson, 2009, for a review). The hippocampus is part of
the recollection process pathway and a component of the MTL that is
central to the association of information units and their context
(Eichenbaum, Sauvage, Fortin, Komorowski, & Lipton, 2012). Re-
cent investigation of content representation in the MTL (Liang, Wag-
ner, & Preston, 2013) showed that a part of the hippocampus is
content general, and another part has more sensitivity to visual scenes.
In another study of the recollection brain pathway (Johnson, Suzuki,
& Rugg, 2013), the authors concluded that recollection-based epi-
sodic recognition relies on both content-sensitive and content-
insensitive processes.
Studies of the picture superiority effect (PSE; Shepard, 1967;
reviewed by Mintzer & Snodgrass, 1999) established that the presen-
tation of pictures, rather than words, has a beneficial effect on item
recognition. Recently, Hockley showed that the PSE also prevail in
associative recognition of young adults (Hockley, 2008; Hockley &
Bancroft, 2011).
