Auditory Sensory Memory

The mismatch negativity (MMN) event-related potential (ERP) component is elicited by any discriminable change in series of repetitive auditory stimuli. MMN is generated by a process registering the deviation of the incoming stimulus from the trace of the previous repetitive stimulus. Using MMN as a probe into auditory sensory memory, the present study addressed the question of whether the sensory memory representation is formed strictly on the basis of an automatic feature analysis of incoming sensory stimuli or information from long-term memory is also incorporated. Trains of 6 tone bursts (standards with up to 1 deviant per train) separated by 9.5-sec intertrain intervals were presented to subjects performing a visual tracking task and disregarding the auditory stimuli. Trains were grouped into stimulus blocks of 20 trains with a 2-min rest period between blocks. In the Constant-Standard Condition, both standard and deviant stimuli remained fixed across the session, encouraging the formation of a long-term memory representation. To eliminate the carryover of sensory storage from one train to the next, the first 3.6 sec of the intertrain interval was filled with 6 tones of random frequencies. In the Roving-Standard Condition, the standard changed from train to train and the intervening tones were omitted. It was found that MMN was elicited by deviants presented in Position 2 of the trains in the Constant-Standard Condition revealing that a single reminder of the constant standard reactivated the standard-stimulus representation. The MMN amplitude increased across trials within each stimulus block in the Constant- but not in the Roving-Standard Condition, demonstrating long-term learning in that condition (i.e., the standard-stimulus trace indexed by the MMN amplitude benefitted from the presentations of the constant standard in the previous trains). The present results suggest that the transient auditory sensory memory representation underlying the MMN is facilitated by a longer-term representation of the corresponding stimulus.

AbstractVowel harmony is a phonotactic principle that requires adjacent vowels to agree in certain vowel features. Phonological theory considers this principle to be represented in one's native grammar, but its abstractness and perceptual consequences remain a matter of debate. In this paper, we are interested in the brain's response to violations of harmony in Turkish. For this purpose, we test two acoustically close and two acoustically distant vowel pairs in Turkish, involving different kinds of harmony violations. Our measure is the Mismatch Negativity (MMN), an automatic change detection response of the brain that has previously been applied for the study of native phoneme representations in a variety of languages. The results of our experiment support the view that vowel harmony is a phonological principle with a language-specific long-term memory representation. Asymmetries in MMN responses support a phonological analysis of the pattern of results, but do not provide evidence for a pure acoustic or a pure probabilistic approach. Phonological analyses are given within Optimality Theory (OT) and within an underspecification account.

Memory Register

Visual tracking is a challenging computer vision task due to the significant observation changes of the target. By contrast, the tracking task is relatively easy for humans. In this article, we propose a tracker inspired by the cognitive psychological memory mechanism, which decomposes the tracking task into sensory memory register, short-term memory tracker, and long-term memory tracker like humans. The sensory memory register captures information with three-dimensional perception; the short-term memory tracker builds the highly plastic observation model via memory rehearsal; the long-term memory tracker builds the highly stable observation model via memory encoding and retrieval. With the cooperative models, the tracker can easily handle various tracking scenarios. In addition, an appearance-shape learning method is proposed to update the two-dimensional appearance model and three-dimensional shape model appropriately. Extensive experimental results on a large-scale benchmark data set demonstrate that the proposed method outperforms the state-of-the-art two-dimensional and three-dimensional trackers in terms of efficiency, accuracy, and robustness.

Inductive Approach

Colours are mentioned many times in the Holy Qur’an. Some are mentioned as colours in general, and some of them in specific; yellow, white, black, red, green and blue. Each colour has its special connotations in the Holy Qur’an and among these colours, yellow and red are considered as warm colours. This study aimed to find the significance of warm colours in the Holy Qur’an and its relationship to human psychology; focusing on memory performance. This research had used an inductive approach in terms of selecting Quranic verses; in which yellow and red colour were mentioned. These verses were then analysed by referring to the books of exegetical considerations in order to know the implications of these colours’ usage, as well as referring to psychology books and scientific articles. The research found that yellow and red colour in the Holy Qur’an mostly indicate attracting attention or pleasing viewers. Some examples included the yellow colour in resemblance to the colour of the cow, attention to decay and destruction such as yellow colour in the withering plants, and attention to resurrection like the red colour resembling scene of the Day of Resurrection. This indication in the Holy Qur’an is consistent with psychologists’ discovery; warm colours such as red and yellow are more effective and attractive in the process of transferring information from external to sensory memory, and thus to short-term and long-term memory.

Practical Implications

Two hundred forty subjects working alone and in pairs performed three different versions of a task similar to industrial inspection: a rating task and spatial and temporal two-alternative forced-choice (2AFC) tasks. Performance was worse on the rating task than on the 2AFC tasks, and the spatial and temporal 2AFC tasks were performed equally well. These results could signify that performance is impaired more by demands made on long-term memory than by demands made on perception and sensory memory, or that asking subjects to compare items is fundamentally different from, and easier than, asking subjects to judge items in absolute terms. Individual differences in performance were marked, but performance was inconsistent across different versions of the inspection task. When subjects worked in pairs, performance was comparable to that obtained by requiring items to pass two inspections by individual subjects. However, a single inspection by subject pairs required less time than two inspections by individual subjects. The practical implications of these findings are discussed.

Hebb Repetition Effect

In tests of working memory with verbal or spatial materials repeating the same memory sets across trials leads to improved memory performance. This well-established “Hebb repetition effect” could not be shown for visual materials. This absence of the Hebb effect can be explained in two ways: Either persons fail to acquire a long-term memory representation of the repeated memory sets, or they acquire such long-term memory representations, but fail to use them during the working memory task. In two experiments, (N1 = 18 and N2 = 30), we aimed to decide between these two possibilities by manipulating the long-term memory knowledge of some of the memory sets used in a change-detection task. Before the change-detection test, participants learned three arrays of colors to criterion. The subsequent change-detection test contained both previously learned and new color arrays. Change detection performance was better on previously learned compared to new arrays, showing that long-term memory is used in change detection.

Central Target

We spend a lot of time searching for things. If we know what we are looking for in advance, a memory representation of the target will be created to guide search. But if the identity of the search target is revealed simultaneously with the presentation of the search array, is a similar memory representation formed? In the present study, 96 observers determined whether a central target was present in a peripheral search array. The results revealed that as long as the central target remained available for inspection (even if only in iconic memory), observers reinspected it after each distractor was checked, apparently forgoing consolidation of the target into working memory. The present findings challenged the assumption that evaluating items in a search array must involve comparison with a template in working memory.

Regulated Learning

Abstract Models of self-regulated learning emphasize the active and intentional role of learners and, thereby, focus mainly on conscious processes in working memory and long-term memory. Cognitive load theory supports this view on learning. As a result, both fields of research ignore the potential role of unconscious processes for learning. In this review paper, we propose an interactive layers model on self-regulated learning and cognitive load that considers sensory memory, working memory, and long-term memory. The model distinguishes between (a) unconscious self-regulated learning initiated by so-called resonant states in sensory memory and (b) conscious self-regulated learning of scheme construction in working memory. In contrast with conscious self-regulation, unconscious self-regulation induces no cognitive load. The model describes conscious and unconscious self-regulation in three different layers: a content layer, a learning strategy layer, and a metacognitive layer. Interactions of the three layers reflect processes of monitoring and control. We first substantiate the model based on a narrative review. Afterwards, we illustrate how the model contributes to re-interpretation of inconsistent empirical findings reported in the existing literature.
