Other factors, such as the strength of the memory and the strength of the reactivation, also appear to be important. In particular, in accordance with [9] model, we found different outcomes consistent with the measures considered. In the current paper, we aimed to study how updating of long-term memory (LTM) bindings (or LTM associations) develops in primary school children (in particular from third to fifth grade). They did not present any specific learning, neurological or psychiatric disorder. The major distinction is between the capacity for conscious, declarative memory about facts and events and a collection of unconscious, nondeclarative memory abilities, such as skill learning and habit learning. A main effect of Age Group reached significance, F(1, 87) = 8.38, p = .005. The model revealed a significant effect of Age Group, F(1, 85.250) = 16.92, p < .001. Science progresses in step with the development of new tools and paradigms that make it possible to ask new questions. In addition, low frequency associations, typically, were in the middle of the lemma, whereas high frequency lemmas were at the beginning of the lemma.

The peak increase in activity was observed at a time after learning when medial prefrontal cortex had become necessary for memory retrieval. These developmental improvements may be driven by increases in storage capacity [7], rehearsal strategies [8], or also updating processes [9]. Indeed, we found significantly longer RTs for correct recognition of a target probe from strong-to-weak associations (M = 2058.33 ms, SD = 58 ms), compared to weak-to-weak associations (M = 1867.85 ms, SD = 43 ms). The real challenge in updating (i.e., due to control for previously relevant information) elicits significantly better performance from 10 years onwards. The modulation of association strength development in older children (but not in younger) could be well accounted by the development of both lexico-orthographic knowledge and executive mechanisms that can work simultaneously [5, 6]. Accordingly, the online RT showed a global age-related effect (older children faster than younger children), but not specific for strength with which letter were associated (in fact, no interaction). Accordingly, item frequency effects on recall are observed with the relevant item only, and occur at the time the individual item is retrieved/recalled (see also [20, 21, 25]). These were accounted for by similar redintegration processes that would operate effectively on high frequency words because their phonological representations are more easily accessed by partial information. Notably, these results indicated that, from 10 years onward, children found highly familiar stimuli (such as letters) more intrusive and difficult to control when strongly associated. Cumulative behavioral work, together with neuroanatomical studies, eventually identified the anatomical components of the medial temporal lobe memory system that support declarative memory (Squire and Zola-Morgan, 1991): the hippocampus (including the CA fields, the dentate gyrus, and the subicular complex), together with the adjacent entorhinal, perirhinal, and parahippocampal cortices that make up much of the parahippocampal gyrus. Indeed, updating can be distinguished from recall, as it allows memory focus to remain attuned to the most relevant information in any specific moment. Therefore, although we find that older children are less susceptible to interference, it seems that they are more sensitive to strong and weakly associated stimuli, similarly to performance in adults [14, 26]. This evidence supported the idea that the nature of updating rests in the interplay between dismantling and reconstructing bindings via different memory systems such as WM [11, 24] and episodic LTM [13]. Memory is one of the most fundamental mental processes. In fact, the specific organization of semantic LTM was found to enhance recall performance. Next, we inferred strong and weak sub-lexical associations between consonants, based on the lemmas’ frequency.

In particular, RTs for weak-to-weak associations were strongly correlated, r (89) = .84, p < .001, to RTs for strong-to-weak. Children were administered two tasks to assess general cognitive abilities (see following method sections for full description). The model revealed a significant effect of Age Group, F (1, 87) = 8.11, p = .006. A central issue is whether to emphasize that place cells [and recently discovered grid cells (Fyhn et al., 2004)] provide computational equipment to support navigation, independently of memory, or to emphasize that activity in these cells serves to represent the significant features of a task or event, including spatial features, as an early step in establishing a memory.
