Verbal Mediation During Auditory Equivalence Class Formation Using Go/No-Go Successive Matching-to-Sample

AbstractSuccessive matching-to-sample (S-MTS) with a go/no-go response requirement has previously produced equivalence classes with nonverbal auditory stimuli among college students. When participants are required to talk aloud during posttests (protocol analysis), their verbal behavior tends to match their selection performance. However, in some cases, the protocol analysis seems to interfere with posttests, in that equivalence yields are lower when participants are required to talk aloud. Thus, the current study replicated and extended previous research by requiring participants to complete emergence posttests before introducing training for the protocol analysis. Subsequently, participants completed one additional block of the transitivity/equivalence posttest with the talk-aloud requirement. Additionally, participants completed tact and intraverbal tests following emergence posttests to further assess possible verbal-mediation strategies. The results showed that six of eight college students formed equivalence classes, suggesting that previous failures could have been influenced by the talk-aloud requirement. Further, there was a positive correlation between verbal and nonverbal (selection) responses suggesting the possibility that verbal mediation may have contributed to equivalence-class formation.

The role of intraverbal bidirectional naming in the establishment of comparative relations.

The purpose of the current study was to extend the research on the possible role of verbal mediation in the establishment of comparative relations. We conducted four experiments in which 14 participants received conditional discrimination training with nonarbitrary and arbitrary stimuli, followed by derived comparative and transformation of function tests. Participants learned to select the smallest or biggest comparison across multiple exemplars in the presence of abstract samples. Next, participants learned to select arbitrary comparisons in the presence of contextual cues to establish a size ranking among comparisons. To assess verbal mediation during mutual and combinatorial entailment tests, participants were instructed to talk out loud. When they failed to perform correctly during derived relations tests, participants were trained to tact and intraverbally relate stimuli. The results suggest that relational training alone was not sufficient to establish comparative relations and that adult participants engaged in problem solving consistent with intraverbal bidirectional naming during emergent relations tests.

Correspondence Between Vocal-Verbal Behavior and Go/No-Go Responses During the Successive Matching-to-Sample Procedure.

In the current study, eight college students were exposed to a successive matching-to-sample (S-MTS) procedure utilizing non-verbal auditory stimuli consisting of common sounds. During emergent relations tests, participants were asked to talk aloud, and their vocal-verbal statements were transcribed and categorized as class-consistent, class-inconsistent, or irrelevant. All participants met emergence criterion for symmetry and four did so for transitivity/equivalence. Analysis of vocal-verbal statements showed a positive correlation between class-consistent statements emitted by participants and correct selection responses during S-MTS tasks. Such results suggest possible verbal mediation during emergent relations tests.

Geographic variability in limited English proficiency: A cross-cultural study of cognitive profiles.

This study was designed to evaluate the effect of limited English proficiency (LEP) on neurocognitive profiles. Romanian (LEP-RO; n = 59) and Arabic (LEP-AR; n = 30) native speakers were compared to Canadian native speakers of English (NSE; n = 24) on a strategically selected battery of neuropsychological tests. As predicted, participants with LEP demonstrated significantly lower performance on tests with high verbal mediation relative to US norms and the NSE sample (large effects). In contrast, several tests with low verbal mediation were robust to LEP. However, clinically relevant deviations from this general pattern were observed. The level of English proficiency varied significantly within the LEP-RO and was associated with a predictable performance pattern on tests with high verbal mediation. The heterogeneity in cognitive profiles among individuals with LEP challenges the notion that LEP status is a unitary construct. The level of verbal mediation is an imperfect predictor of the performance of LEP examinees during neuropsychological testing. Several commonly used measures were identified that are robust to the deleterious effects of LEP. Administering tests in the examinee's native language may not be the optimal solution to contain the confounding effect of LEP in cognitive evaluations.

Development and validation of the Olfactory Memory Test Battery (OMTB) based on odors with high- and low-verbalizability

BackgroundOdor memory is an important field of clinical research for its distinctive characteristics, which differ from those of other sensory systems. To date, several tests have been implemented for the assessment of odor memory. Despite a range of studies demonstrating the importance of verbal mediation in odor memory, few have distinguished odor memory performance in different odor verbalization levels. New methodWe aimed to develop a standardized odor memory test toolbox with one group of odors that are easily verbally identified and the other group of odors that are difficult to identify. The test contained two odor categories (high- and low-verbalizability odors), each consisting of three subtests (short- and long-term memory and working memory). ResultsSatisfactory test-retest reliability and solid validity of the odor recognition and working memory test were shown in both odor categories. Moreover, people scored significantly better with high- than low-verbalizability odors. A negative age effect on odor memory performance was also found. Comparison with existing methodsNo previous odor memory test distinguished odor memory performance in different odor verbalization levels, while the Olfactory Memory Test Battery (OMTB) contains high- and low-verbalizability odors and each category has three subtests. ConclusionsThe present study indicated the OMTB is a comprehensive assessment of odor memory with good reliability and validity. All subtests can be used separately or in combination with each other according to the clinical and research needs.

The challenge of neuropsychological assessment of visual/visuo-spatial memory: A critical, historical review, and lessons for the present and future.

A proliferation of tests exists for the assessment of auditory-verbal memory processes. However, from a clinical practice perspective, the situation is less clear when it comes to the ready availability of reliable and valid tests for the evaluation of visual/visuo-spatial memory processes. While, at face value, there appear to be a wide range of available tests of visual/visuo-spatial memory, utilizing different types of materials and assessment strategies, a number of criticisms have been, and arguably should be, leveled at the majority of these tests. The criticisms that have been directed toward what are typically considered to be visual/visuo-spatial memory tests, such as (1) the potential for verbal mediation, (2) over-abstraction of stimuli, (3) the requirement of a drawing response, and (4) the lack of sensitivity to unilateral brain lesions, mean that, in reality, the number of readily available valid tests of visual/visuo-spatial memory is, at best, limited. This article offers a critical, historical review on the existing measures and resources for the neuropsychological assessment of visual/visuo-spatial memory, and it showcases some examples of newer tests that have aimed to overcome the challenges of assessing these important aspects of memory. The article also identifies new trends and examples of how technological advances such as virtual reality may add value to overcome previous obstacles to assessment, thereby offering professionals more reliable, accurate means to evaluate visual/visuo-spatial memory in clinical practice.

Cross-Cultural Performance Validity Testing: Managing False Positives in Examinees with Limited English Proficiency

ABSTRACT Base rates of failure (BR Fail ) on performance validity tests (PVTs) were examined in university students with limited English proficiency (LEP). BR Fail was calculated for several free-standing and embedded PVTs. All free-standing PVTs and certain embedded indicators were robust to LEP. However, LEP was associated with unacceptably high BR Fail (20–50%) on several embedded PVTs with high levels of verbal mediation (even multivariate models of PVT could not contain BR Fail ). In conclusion, failing free-standing/dedicated PVTs cannot be attributed to LEP. However, the elevated BR Fail on several embedded PVTs in university students suggest an unacceptably high overall risk of false positives associated with LEP.

Readiness of teacher the interact with students of different nosologies

The readiness of a university teacher to interact with students of different nosologies has a modular basis, represented by personal, gnostic and procedural components. The article analyzes the current level of knowledge of teachers of the Samara State Institute of Culture and Samara University about the specific capabilities of students with various nosologies. This knowledge relates to the mental development of students; abilities to receive, process, store and use information; difficulties in verbal mediation of information storage and use; technical possibilities of organizing the learning process; readiness for collaborative learning. The preparation of university teachers for interaction with students of various nosologies is built on the basis of a system-holistic approach, its main principles: consistency, integrity, structurality, controllability, transformation.

Neurocognitive Profiles Associated With Limited English Proficiency in Cognitively Intact Adults.

The objective of the present study was to examine the neurocognitive profiles associated with limited English proficiency (LEP). A brief neuropsychological battery including measures with high (HVM) and low verbal mediation (LVM) was administered to 80 university students: 40 native speakers of English (NSEs) and 40 with LEP. Consistent with previous research, individuals with LEP performed more poorly on HVM measures and equivalent to NSEs on LVM measures-with some notable exceptions. Low scores on HVM tests should not be interpreted as evidence of acquired cognitive impairment in individuals with LEP, because these measures may systematically underestimate cognitive ability in this population. These findings have important clinical and educational implications.

The Role of Mediational Discourse in Developing an EFL Teacher’s Oral Corrective Feedback Strategies: A Sociocultural Perspective

Taking sociocultural theory (SCT) as a theoretical framework, this qualitative phenomenological case study investigated the mediational discourse of a series of ten observation and post-observation conferences between a coach and an English language teacher teaching at Iran Language Institute (ILI) in Shiraz, Iran, in order to represent the development of student-focused oral feedback in an EFL teacher over time. Features of verbal mediation already identified by Wertsch (1998) such as shared definition of the task, inter-subjectivity, graduated help, and reasoning existed in the data, while they were insufficient in triggering the teacher to think conceptually about his use of oral feedback to students. Similarly, professional discourse, languaging motives, and teacher dynamicity, alongside the aforementioned meditational features, were revealed to be pivotal on the uptake of conceptual thinking by the teacher. The study was divided into three phases, namely, before, during, and after verbal mediations given by the coach to the teacher participant. The results of the study, along with the previous descriptive and empirical studies, accounted for an obvious role of mediational discourse in the development of teacher’s understanding of conceptual thinking through verbally-mediated activity. The results also found that negotiated help given by the teacher to learners was excessively pivotal in assisting learners to internalize their oral errors. The study concluded with some pedagogical implications for second language teachers to be reflective, dynamic, and evaluative in dealing with oral corrective feedback challenges in their classroom practices.

How does language support the acquisition of novel cognitive tasks? Investigating the role of task complexity and task instructions.

Recent findings have shown that language plays an important role in the acquisition of novel cognitive tasks (van 't Wout & Jarrold, 2020). The current study sought to elucidate the factors that influence the contribution of language to novel task learning, focusing specifically on the role of task complexity (defined by the number of stimulus-response [S-R] rules per task) and the role of task instructions (by comparing trial-and-error learning to instruction-based learning). In each experiment participants were required to learn the correct response to novel sets of picture stimuli. When analyzed as a function of stimulus occurrence within a task, both experiments found that initial performance was worse under articulatory suppression (AS; verbal distractor task) than under foot tapping (i.e., nonverbal distractor task), but only if the task was more complex (consisting of 6S-R rules) and not if it was less complex (consisting of three or four S-R rules), suggesting that the acquisition of a simpler task by trial and error might not require verbal mediation. Experiment 2 furthermore found that the role of language was modulated by the manner of acquisition: For trial-and-error learning, the detrimental effect of AS increased and then decreased again as a function of stimulus occurrence. Conversely, for instruction-based learning, AS exclusively affected the first few stimulus occurrences, suggesting that participants can create a verbal representation of the task during the instruction phase. Together, these experiments demonstrate that the role of language in novel task learning is modulated by task complexity and task instructions.

The Use of the Go/No-Go Successive Matching-to-Sample Procedure with Nonverbal Auditory Stimuli to Establish Equivalence Classes and Speaker Behavior.

The purpose of the current study was to extend the findings on the use of the go/no-go successive matching-to-sample (S-MTS) procedure to establish auditory equivalence classes. Eight college students learned to conditionally relate nonverbal auditory stimuli into three, 3-member classes. Following training, all participants met the emergence criterion for symmetry, and six out of eight participants met the emergence criterion for transitivity/equivalence. Furthermore, all participants responded with either an experimenter-defined or a unique tact, and five participants related these names intraverbally. Although these results replicate previous findings, albeit with stimuli that cannot be echoed, possible verbal mediation via tact and intraverbal behavior seems to have occurred.

Visual perception supported by verbal mediation in an individual with cerebral visual impairment (CVI)

Cerebral visual impairment (CVI) often presents with deficits associated with higher order visual processing. We report a case of an individual with CVI who uses a verbal mediation strategy to perceive and interact with his visual surroundings. Visual perceptual performance was assessed using a virtual reality based visual search task combined with eye tracking. Functional magnetic resonance imaging (fMRI) was employed to identify the neural correlates associated with this strategy. We found that when using verbal mediation, the individual could readily detect and track the target within the visual scene which was associated with robust activation within a network of occipito-parieto-temporal visual cortical areas. In contrast, when not using verbal mediation, the individual was completely unable to perform the task, and this was associated with dramatically reduced visual cortical activation. This unique compensatory strategy may be related to the individual's use of verbal working memory for the purposes of understanding complex visual information.

The Effects of Competing Verbal Behavior on Performance in a Math Task.

The purposes of this study were to evaluate the effects of an auditory-distractor stimulus and vocal-blocking task on performance on a math task and measures of overt verbal operants. College students served as participants, and they were instructed to solve an arithmetic problem while continuously emitting overt verbal behavior. The overt verbal behavior consisted of either talking aloud while solving the problem or reciting the alphabet. A third condition consisted of playing an auditory-distractor file containing the alphabet during the response interval while participants talked aloud. Data were collected on response accuracy, latency to respond, and frequency of echoic and self-echoic responses emitted during the response interval. The vocal-blocking task significantly affected performance on the math task when visual stimuli were absent. The decrease in performance coincided with significant decreases in participants' mean frequency of echoic and self-echoic responses. In sum, correctly responding to an arithmetic problem was significantly affected by the vocal-blocking task, indicating support for the necessity of verbal mediation during problem solving.

Responding Fails to Extinguish During Human-Laboratory Experiments of Resurgence

Resurgence is observed when a previously extinguished behavior reemerges while a more recently reinforced behavior is extinguished. Resurgence is further defined as responding that is greater than an inactive control response that has never produced reinforcement. Recent studies of resurgence using neurotypical adults as participants in human-laboratory investigations have produced discrepant patterns of responding compared to nonhuman animal laboratory studies when comparing control response performance. Namely, human-laboratory investigations have produced no differences between target and control responding, and persistence of all response types across the resurgence-test phase. In the present study, we conducted two human-laboratory experiments to determine if these effects were a product of the history of reinforcement associated with the target response as well as the types of technology used in human-laboratory studies. For all participants, we found no differences in levels of resurgence and occurrence for the target and control response, respectively. Moreover, we observed persistence of all response types across the resurgence-test phase in a manner consistent with prior research. This finding was apparent even when the length of baseline (i.e., reinforcement for the target) was increased, when the length of extinction was increased, and when low-technology stimuli were used. We highlight the implications of this outcome in the context of recent human-laboratory studies that have used arbitrary responses to study resurgence, and discuss the possible role of verbal mediation in these investigations.

Maternal mediation strategies during interaction with toddlers- a comparison of dyads with autism spectrum disorder (ASD) and dyads with typical development (TD)

IntroductionDuring interactions with toddlers, mothers use various mediation strategies to encourage mutual play. Such mediation skills play an important role in the development of toddlers’ communicative skills. Autism Spectrum Disorder (ASD) introduces challenges to this interaction.ObjectivesTo study the use of maternal strategies during interaction with ASD and TD toddlers at early lexical levels.MethodsNine ASD and fifteen TD dyads participated. Toddlers were matched by lexical levels. The mean age in the ASD was 31.5 months and in TD - 17 months. Each dyad was video-recorded three times, during naturalistic interaction. Mothers’ verbal mediation strategies were divided into five main communicative categories.Results1. Exact repetition of toddler’s utterances was similarly used and increased in both groups across the three visits (f (2,44)=3.77, p< 0.05). 2. Significant differences were found between the two groups regarding strategies associated with control of the interaction eg mothers of toddlers with ASD (MASD) made more frequent attempts to redirect their child’s attention (F (1,22)= 74.56, p<0.01). 3. MASD had higher indices of overall talkativeness (F (1,22)= 5.43, p<0.05); use of nonverbal means (F(1,22)= 9,51, p<0.01); simultaneous use of different means of communication (F (1,22)=19.8, p<0.01).ConclusionsOur results highlight that in some respects, maternal mediation strategies reflect the child’s lexical level. However, our main finding is a distinct interaction style expressed in MASD’s elevated use of verbal and nonverbal mediation strategies. This, in hope of maintaining continuous interaction that could not be otherwise achieved due to their toddlers’ difficultiesDisclosureNo significant relationships.

Verbal mediation of theory of mind in verbal adolescents with autism spectrum disorder

ABSTRACT This study tests the role of verbal mediation during theory of mind processing in autism spectrum disorder (ASD). Adolescents with ASD or typical development completed a false belief task while simultaneously performing a verbal or nonverbal load task. There was no group difference in false belief accuracy; however, under verbal load, the ASD group was relatively less efficient, with slower reaction times, in false belief compared to true belief trials. Faster false belief task performance under verbal but not nonverbal load was associated with pragmatic language ability for the ASD group only. Results were consistent with the theory that there are two (implicit, nonverbal and explicit, verbal) processes that support cognitive reasoning about other people’s minds and that people with ASD rely more on the explicit system. Verbal mediation may be critical for false belief understanding in individuals with ASD but not typical development.

Manual Responses Are Verbally Mediated in Stroop Identification Tasks

In a typical Stroop experiment, participants view a color word written in a color that is either congruent or incongruent with the word’s meaning and identify either the target’s color (Stroop condition) or meaning (reverse Stroop condition). Incongruent words generally interfere with identifying the target color more than incongruent colors interfere with identifying the target word. A common explanation for this classic asymmetry asserts that vocally identifying the target’s color or meaning relies on a verbal code, which biases attention to the target’s meaning over its color. However, the asymmetry also occurs with nonverbal keypress responses, so participants may covertly map verbal codes onto keys to remember which key represents each color. To verify this verbal mediation hypothesis, we presented Stroop color-word targets along with 4 cues to help participants remember which key represented each color. In one condition the cues were color words, and in the other the cues were color patches. We hypothesized that the word cues would elicit the classic asymmetry and color cues would abolish this asymmetry. The results supported our hypotheses; for word cues the Stroop effect was larger than the reverse Stroop effect, p < .001, ηp2 = .64, and color cues abolished this difference, p < .001, ηp2 = .31. This study is the first to provide direct confirmation of the verbal mediation hypothesis and suggests that task demands are more important than the response modality (vocal versus manual) for biasing processing toward one of the Stroop target’s features.

ПСИХОДИДАКТИЧНІ ЗАСАДИ УКЛАДАННЯ ПІДРУЧНИКІВ ДЛЯ УЧНІВ З ПОРУШЕННЯМИ ІНТЕЛЕКТУАЛЬНОГО РОЗВИТКУ

In the light of educational reform in Ukraine on the way to European values of equality and nondiscrimination, general secondary education institutions with an inclusive form of education should receive educational materials that meet the needs, interests, individual characteristics and capabilities of each student, including students with intellectual disabilities. The functions of differentiated and individualized teaching of a modern textbook indicate the need to reconsider the role of the school textbook in an inclusive educational space. Yes, it should not be exclusively a source of information, it should be a factor in the intellectual development of students according to their needs and abilities. Accordingly, the school textbook in content, form and design should be a projection not only of scientific knowledge, but also the basic laws of intellectual development of the individual in the learning process. The article considers the main requirements for the textbook for students with intellectual disabilities. These students are characterized by a slowdown in the speed of receiving and processing information; general decrease in mental activity and, as a consequence, narrowing of a stock of knowledge and representations about the world around and about itself; speech disorders, communication difficulties; insufficiency of verbal mediation of activity, inconsistency of figurative and verbal spheres of psyche, etc. Adherence to the methodological requirements for the school textbook for students with intellectual disabilities involves the compliance of materials with the age characteristics of students in terms of content, emotional impact; clear structural division and graphical selection of conclusions, key provisions, key concepts, etc .; a sufficient number of illustrations that facilitate the perception, understanding and memorization of educational material, conveniently located and associated with the text; inclusion of tasks that stimulate the development of a certain degree of independence in solving problems, the formation of skills to use the stock of available knowledge. All these requirements are met when selecting verbal material (articles, exercises, examples) for explanation, consolidation, repetition of educational material, methodological apparatus (rules, instructions, tasks, questions), illustrations (drawings, photographs, graphs, etc.).
