INVESTIGATING THE ASYMMETRIC NATURE OF THE CONTIGUITY EFFECT VIA PROBED RECALL TASK

ARPACI, Hazal
In free recall, there is a tendency to generate a word that either follows or precedes the just recalled word in the study list, which is known as the contiguity effect. This effect has been explained by two main accounts: causal models and non-causal models. Causal models claim that the contiguity effect occurs due to the utilization of the just recalled item as a cue to recall the next item, whereas according to non-causal models, items are not used as cues, but instead the similarity between the mental state during the study and test phases results in the contiguity effect. Probed recall task is designed to test these two models to explain the mechanisms underlying the effect. However, the forward asymmetry that is usually observed in the contiguity effect was not observed in the probed recall task. It was suggested that the overall low performance could be the reason behind the symmetrical contiguity effect. Therefore, in this study, the probed recall task has been attempted to be optimized and facilitated. To that aim, 2 Experiments (and 2 Pilot Experiments) have been conducted. The results of the experiments have shown that the contiguity effect has been observed in both within-list and between-list conditions. Moreover, forward asymmetry has been observed in the between-list (long-term) contiguity effect, but not in the within-list contiguity effect. With the findings of contiguity effects and asymmetry in long-term contiguity effect, this study supports the claims of causal models.

Testing Encoding and Retrieval Dynamics of Pairs Using Probed Recall Task
Hato, Tuğba; Kılıç Özhan, Aslı; Department of Psychology (2022-9)
In free recall, subjects tend to successively recall words studied in nearby positions, denoted as the contiguity effect, favoring the following word over the preceding one. Whereas in paired associates, recall probabilities of forward and backward recalls are approximately equal. The associative symmetry hypothesis (ASH) suggests holistic encoding of pairs, whereas the independent association hypothesis (IAH) separate the encoding of forward and backward. Two main classes of memory models aim to explain th...
A causal contiguity effect that persists across time scales.
Kılıç Özhan, Aslı; Howard, MW (2013-01-01)
The contiguity effect refers to the tendency to recall an item from nearby study positions of the just recalled item. Causal models of contiguity suggest that recalled items are used as probes, causing a change in the memory state for subsequent recall attempts. Noncausal models of the contiguity effect assume the Memory state is unaffected by recall per se, relying instead on the correlation between the memory states at study and at test to drive contiguity. We examined the contiguity effect in a probed re...

Investigation of novel topological indices and their applications in organic chemistry
Gümüş, Selçuk; Türker, Burhan Lemi; Department of Chemistry (2009)
Numerical descriptors, beginning with Wiener, and then named topological indices by Hosoya, have gained gradually increasing importance along with other descriptors for use in QSAR and QSPR studies. Being able to estimate the physical or chemical properties of a yet nonexistent substance as close as possible is very important due to huge consumption of time and money upon direct synthesis. In addition, one may face safety problem as in the case of explosives. There have been almost hundred topological indic...
Formation of languages; Equality, hierarchy and teachers
Tuncay, Çağlar (World Scientific Pub Co Pte Lt, 2007-06-01)
A quantitative method is suggested, where meanings of words, and grammatic rules about these, of a vocabulary are represented by real numbers. People meet randomly, and average their vocabularies if they are equal; otherwise they either copy from higher hierarchy or stay idle. The presence of teachers broadcasting the same (but arbitrarily chosen) vocabulary leads the language formations to converge more quickly.
