“…Intentional remembering increases memory and hippocampal activity and, unsurprisingly, increases viewing behavior [72]. Influences of intentional remembering on memory therefore cannot be easily separated from the effects of intentionality on viewing behavior.…”

Current interpretations of hippocampal memory function are blind to the fact that viewing behaviors are pervasive and complicate the relationships among perception, behavior, memory, and brain activity. For example, hippocampal activity and associative memory demands increase with stimulus complexity. Stimulus complexity also strongly modulates viewing. Associative processing and viewing thus are often confounded, rendering interpretation of hippocampal activity ambiguous. Similar considerations challenge many accounts of hippocampal function. To explain relationships between memory and viewing, we propose that the hippocampus supports online memory demands needed to guide visual exploration. Hippocampus thus orchestrates memory-guided exploration that unfolds over time to build coherent memories. This new perspective on hippocampal function harmonizes with the fact that memory formation and exploratory viewing are tightly intertwined.

“…Furthermore, deficiencies in remembering the positions of objects in a picture have also been observed (Shih et al 2012). Memory of object location was deficient in older adults when associations between objects and locations were required in the tasks (Kessels et al 2005) as well as when only contextual information was evaluated (object position, without attending to its identity).…”

“…Moreover, the specific evaluation of spatial location memory confirmed a marked loss of memory under incidental learning conditions for older adults. In fact, older adults with poor performance while learning spatial locations under incidental learning had better performance under intentional learning and encoding information (Shih et al 2012). …”

The differential characteristics of absolute power in the EEG theta (4-8 Hz) and gamma (30-45 Hz) frequency bands have been analysed in young (18-25 years old, n = 14) and mature adults (45-65 years old, n = 12) during the incidental or intentional behavioural conditions of learning and recalling in a visuospatial task. A printed drawing of a maze including eight figures of common objects in specific placements, solved by connecting its entrance and exit points, allowed the subject's performance efficiency to be measured based on the number, position accuracy and/or identity of incidentally or intentionally learned and remembered objects. Meanwhile, EEG recordings from frontal, parietal and temporal derivations were obtained to determine the power values of the theta (4-8 Hz) and gamma (30-45 Hz) bands for each behavioural condition and derivation. Relative to the young adults, the mature adults generally showed lower absolute theta power values, mainly due to their low theta powers under the basal and incidental learning conditions, and higher absolute gamma power values in the frontal and temporal regions. Furthermore, higher theta band power in the frontal regions was related to higher performance efficiency in both incidental and intentional learning, regardless of the subjects' age. A significant negative correlation between the parameters of individual incidental or intentional learning performance and age was also found. Indeed, a differential accuracy of remembered information seems to be associated with age and incidental or intentional learning/memory testing conditions. These data support an increasing vulnerability of visuospatial learning abilities at mature ages and as ageing progresses.

“…In Williams et al the objects were clearly defined, encoding was incidental, and the task assessed longer-term memory (LTM). When encoding instructions were manipulated (incidental vs intentional) in younger and older adults, Shih, Meadmore, and Liversedge (2012) showed that both instructions and age affected viewing behaviours and memory about clearly defined objects and, more importantly, that recognition performance of the older adults improved under intentional instructions and the improvement was due to more and longer fixations on objects.…”

We examined whether there were age-related differences in eye movements during intentional encoding of a photographed scene that might account for age-related differences in memory of objects in the scene. Younger and older adults exhibited similar scan path patterns, and visited each region of interest in the scene with similar frequency and duration. Despite the similarity in viewing, there were fundamental differences in the viewing-memory relationship. Although overall recognition was poorer in the older than younger adults, there was no age effect on recognition probability for objects visited only once. More importantly, re-visits to objects brought gain in recognition probability for the younger adults, but not for the older adults. These results suggest that the age-related differences in object recognition performance are in part due to inefficient integration of information from working memory to longer-term memory.
