ilarity was manipulated at test. Behavioral results showed the effects
of both perceptual and semantic manipulations; ERPs results showed
that, within the same 300–550-msec poststimulus time window, amplitudes
for perceptually driven judgments went in opposite directions
to amplitudes for conceptually driven judgments with respect to baseline.
These findings suggest a possible dissociation between perceptual
and semantic bases for familiarity. The same experiment was also
carried out using a speed–accuracy trade-off technique (signal response
procedure—without ERPs recordings) and consistent data
were obtained with respect to familiarity’s time course.

The Role of Past in the Simulation of Autobiographical Future
Episodes: A Study With Young and Old Adults. NADIA GAMBOZ
& MARIA A. BRANDIMONTE, Suor Orsola Benincasa University
(sponsored by Maria A. Brandimonte)—Human beings’ ability to envisage
the future has been recently assumed to rely on the reconstructive
nature of episodic memory (Schacter & Addis, 2007). In this
research, young and old adults mentally reexperienced and preexperienced
temporally close and distant autobiographical episodes, and
rated their phenomenological characteristics (D’Argembeau & Van
der Linden, 2004). Additionally, they performed a delayed recognition
task including remember–know judgments on new, old-remember,
and old-imagine words. The results showed that, for both age groups,
past and future temporally close episodes included more phenomenal
details than did distant episodes, in line with the episodic constructive
simulation hypothesis (Schacter & Addis, 2007). However, in the
recognition task, both groups falsely attributed, with a high level of
confidence, old-imagine words to remembered episodes. While partially
in line with previous results, these findings call for a more subtle
analysis in order to discriminate representations of past episodes
from true future events simulations.

Recognition Without Identification of Songs. BOGDAN KOSTIC &
ANNE M. CLEARY, Colorado State University—Recognition without
identification (RWI) is discrimination between studied and nonstudied
items that are unidentified. This study examined RWI in music.
Participants heard brief piano songs at study. In Experiment 1, identification
at test was hindered through song fragmentation. An RWI
effect was shown; among unidentified songs, participants discriminated
between auditory fragments of studied and nonstudied songs
(even with low identification rates, and even when the songs had been
identifiable at study). Experiment 2 showed that song RWI can be
based on a song’s isolated rhythm. Experiment 3 showed that it can be
based on a song’s tonal information separated from its rhythm; how-

ever, without the original rhythm, maintaining note order is critical for
obtaining the RWI effect. Thus, song RWI requires either some of the
song’s rhythm or some ordered tonal information during recognition.
Implications for theories of recognition memory and theories of music
cognition are discussed.

Action–Sentence Compatibility and Its Impact on Recognition
Memory. DOMINIC A. SIMON, New Mexico State University—In an
attempt to replicate the action–sentence compatibility effect (ACE,
Glenberg & Kaschak, 2002) and to determine its impact on memory,
participants read sentences and then moved a mouse to indicate their
judgments of sentence sensibility. Sentences varied in sensibility, concreteness,
implied movement direction, and compatibility between
implied and appropriate response movement direction. The ACE was
partially replicated: For sentence reading times, there was a significant
interaction between implied direction and response direction
compatibility such that compatible sentences were read relatively
quickly when the implied direction was away from the reader, but
slowly when it was toward. Main effects also emerged for implied direction
and concreteness. On a test of sentence recognition, abstract
sentences were better remembered than concrete ones, and there was
an interaction between concreteness, implied movement, and compatibility
of the response direction. As hypothesized, action–sentence
compatibility affected sentence recognition, though not in a straightforward
manner.

Serial Memory for Real-World Objects: How Visually Precise?
DANIEL A. GAJEWSKI & JOHN W. PHILBECK, George Washington
University—Is immediate memory for real-world objects more visually
precise than memory over longer retention intervals? Experiment
1 examined object memory as a function of serial position in a
forced-choice recognition task with the visual similarity of differenttoken
distractors manipulated to probe the visual precision of memory.
Accuracy was greater for the most recently viewed objects and
when the distractors were dissimilar. Surprisingly, the effect of similarity
did not differ across serial positions. Experiment 2 included a
test-delay manipulation (immediate vs. end of session) to further extend
the interval between exposure and test. Overall performance declined
when the test was delayed until the end of the session, but the
effect of distractor similarity again did not depend on the timing of
the test. The results suggest that whereas the probability of successful
retrieval changes over the course of viewing, the precision of the
memory upon successful retrieval is relatively stable.
