Determinants of auditory-visual integration in elementary school education

Kerr, Andrew Stewart January 1970 (has links)
This study was designed to examine a number of factors which might affect the ability to equate auditory and visual non-verbal stimuli as measured by performance on the auditory-visual integration (AVI) test of Birch & Belmont (1964, 1965) and Kahn & Birch (1968) . In this test S is presented with an auditory dot pattern and is required to identify the one of three printed visual dot patterns which is the same as the one heard. Short-term auditory memory, stimulus length and sex differences were studied as possible factors affecting performance on the AVI test. A random selection, from three elementary schools, of 108 third-grade children, 54 males and 54 females, were assigned to one of two groups. Two modified forms of the AVI test defined as the consecutive presentation and the simultaneous presentation, were administered, one to each group of Ss. The first of these tests presented the auditory and visual, stimuli consecutively; that is, the auditory stimulus, after a delay of 5 sec., was followed by three visual stimuli presented one at a time, of which one corresponded to the auditory stimulus. It was proposed that this presentation format would involve short-term auditory memory as a possible factor affecting the judgments of auditory-visual equivalence. The second test presented the auditory and visual stimuli simultaneously as pairs; that is, there was no delay between the auditory and visual stimuli. Each of three visual stimuli was presented simultaneously with the same auditory stimulus. It was assumed that this presentation would eliminate short-term auditory memory as a factor affecting auditory-visual integration competence. It was found that third-grade children were able to process the simultaneous presentation of auditory and visual non-verbal stimuli, at certain stimulus lengths, with more facility than they were when the same stimuli were presented in the consecutive mode. This result supported the hypothesis that there might be a significant short-term auditory memory factor in performance of the AVI test and that this memory component might be significantly related to judgments of auditory-visual equivalence. The position of the visual stimuli was also found to affect the recognition of auditory and visual pairs in the AVI test. The effect, significant though small, occurred for both the consecutive and simultaneous presentations, indicating that interference or decay of sensory processing did occur whether the presentation was consecutive or simultaneous for stimuli in the third position. It was suggested that interference and/or decay in short-term memory, might account for the impaired ability to make correct judgments of auditory-visual equivalence for stimuli in position three as compared to stimuli in positions one and two for the consecutive presentation. The assumption of proactive interference was invoked to account for the occurrence of the same phenomenon in the simultaneous presentation. Another finding indicated that stimulus length per se might not be a significant factor affecting the difficulty of auditory-visual equivalence judgments, but that a factor related to length might be. The results are consistent with a theory of recoding input stimuli and suggest that an increase in the number of units of stimuli to be retained and not the number of stimuli per unit, might be the factor affecting the difficulty level of auditory-visual equivalence judgments. Sex of the children was not found to affect performance on the AVI tests significantly. Further research considerations in the area of AVI were advanced. / Education, Faculty of / Graduate

Input-output modes and short-term memory for object sequences in grade I children

Koopman, Peggy Rae January 1968 (has links)
In the study of differential abilities in learning and in the diagnosis and remediation of learning disabilities, much attention has been paid to the mode in which material is presented or becomes available (input), and to the form in which response is made (output). Following common practice, the input modes used in this study are Auditory, Visual, and Haptic (tactile-kinesthetic), and the output modes are Vocal and Motor. Different investigators have stressed either the input modes or the output modes as critical in the development or amelioration of learning disabilities. Reports reaching the writer from teachers and clinicians have described learning problems that seem unexplainable in terms of such input or output effects. This study advances and tests the proposition that, important as input and output modes may be separately in accounting for children's performances, there are children for whom input and output modes operate interactively instead of (or as well as) independently. The task chosen for the experiment was one of memory for object sequences. It involved presenting, under each of the three input conditions separately, sequences of familiar objects increasing in number from two to eight. The subjects were 90 Grade I Vancouver, B.C., children. Following each sequence, every subject was required to indicate the objects that had been presented. This was done independently under both vocal and motor output conditions. To increase reliability, three sequences were presented at each sequence-length. Each child was given two replications on all input-output combinations, with an interval of two weeks. Scoring was designed to take account of both the length of sequence that a child could recall correctly, and the number and kinds of error that he made under each combination of input and output modes. The resulting scores were viewed as entries in a four-factor experiment having two fixed factors (3 levels of Input and 2 levels of Output) and two random factors (90 subjects and 2 replications). Standard ANOVA procedures reveal, as hypothesized, a highly significant Subjects x Input x Output interaction. There is also a highly significant Subjects x Input interaction and a less impressive but nonchance Subjects x Output interaction. Estimates of variance components associated with each of these effects show the S x I x 0 interaction to account for about as much variance as the total of the two-way interactions, giving a clear indication of the potential importance of Input x Output combinations in learning diagnoses. The scoring patterns of individual children were analyzed. Certain children were found to have performed particularly well or badly under specific combinations of input and output modes that seemed to be unrelated to whatever input or output strengths or weaknesses they had. The implications of this interactive role of input and output modes were explored and resulted in recommendations for teachers and clinicians, as well as for further research. / Education, Faculty of / Educational Studies (EDST), Department of / Graduate

Avoidance learning to stimulus objects presented following shock

Keith-Lucas, Timothy, 1945- 01 February 2017 (has links)
An earlier informal experiment by Hudson (1950) in which rats learned to avoid a bundle of pipe cleaners presented only following shock is replica.ted and extended. Five groups of 20 Ss each received a single shock each while taking a sucrose pellet from a novel striped panel, A black-out period ranging from 1 to 40 sec. began with the onset of the 3/4 sec. shock. During the black-out the striped panel (forward-order CS) was removed; immediately following the black-out, a rubber toy hedgehog descended into the apparatus, Following a short exposure to the toy hedgehog and an intervening 24 hr. in the home cage, S was observed in the apparatus with the toy hedgehog at one end and the striped panel at the other. Control groups received either shock without the toy hedgehog or the toy hedgehog without the shock. All behavior was video recorded. Significant differential avoidance of the toy hedgehog occurred in the short inter stimulus interval groups (1, 5, and 10 sec.), but not in the 40 seCc group or in the control groups. In further analyses, individual’s were classified as differentially avoiding either the toy hedgehog, the striped panel, the shock location, the opposite end of the apparatus or no identifiable stimulus, according to two schemes. In the first, the basis of classification was differences in time spent in a normal posture at the two ends of the apparatus relative to a distribution of such differences in the unshocked control group. In the other, a combined score derived from differences in four other classes of behavior was the basis of classification. In both analyses, significant numbers of Ss from the 1, 5, and 10 sec. groups were identified as avoiding the toy hedgehog, while insignificant numbers of Ss from the 40 sec. and control groups did so. Only insignificant numbers of Ss avoided the striped panel. The results demonstrate that the "backward" association of the toy hedgehog with the shock is a reliable and robust phenomenon that can occur despite a 10 sec. UCS-CS delay, a single trial procedure, a 24-hr. delay between shock and testing, and the availability of a potential forward - order CS. The results cannot readily be explained either in terms of an unconditioned response to the toy hedgehog or simple sensitization. Both logical considerations and experimental results in backward conditioning preclude describing these results in terms of stimulus cuing. The results are interpreted as a. demonstration of the ability of rats to perceive causal agent-effect relationships in certain specific situations. Support for conclusions drawn from the inference that rats can make causal agent-effect connections is taken from the areas of belongingness, stimulus selection in avoidance learning, delayed taste -avoidance learning, novelty, reflexive aggression, and species-specific defense reactions. Theoretical literature relevant to this inference and the broader question of what is learned is discussed. / This thesis was digitized as part of a project begun in 2014 to increase the number of Duke psychology theses available online.

Undernutrition as a factor in the learning ability of primary school pupils

Luthuli, Cleopatra January 1996 (has links)
A dissertation submitted to the Faculty of Education in fulfilment of the requirements for the Degree of Master of Education in the Department of Philosophy of Education at the University of Zululand, 1996. / The researcher sought to investigate the effect of undernutrition on the learning ability of primary school pupils in the Esikhawini and Kwa-Dlangezwa areas in the district of Empangeni in Kwa Zulu Natal. This study has six chapters. In chapter one the researcher introduces this report and mentions the significance of the study and the plan as to how the study will be carried out. Chapter two and chapter three are both based on research that other researchers have conducted on this topic. It is therefore background information. The researcher exposes the relationship that exists between undernutrition and intellectual development, how the learning ability is affected by undernutrition, for example, pupils who come to school having not had breakfast. Two methods were used in this study, viz literature review and empirical study. Literature review formed the basis of the study whereafter questionnaires were designed. Chapter four details the methodology used to collect data. In chapter five the data is analysed and interpreted whereas in chapter six the researcher summarises the study and makes conclusions and recommendations. This study confirmed that undernutrition impacts negatively on the learning ability of primary school pupils. The study showed that the teachers and pupils regard breakfast as the most important meal because pupils were found to perform better in class when they have eaten breakfast. The learning ability is generally affected when pupils have not eaten food. The study also revealed that most pupils do not bring lunch boxes to school, but they bring money to school so that they can buy something to eat. Teachers showed concern on the food items that pupils buy. They stated that it does not provide the necessary-nutrients for good nutrition. In conclusion, this study showed that the learning ability of pupils is affected by undernutrition, that is, by not getting enough food, especially breakfast and also nutritious food.
