Physiological self-regulation and information processing in infancy: cardiac vagal tone and habituation

This study investigates the role of physiological self-regulation (cardiac vagal tone) in information processing (habituation) in 81 infants. Nucleus ambiguus vagal tone (Vna, a measure of respiratory sinus arrhythmia) was used to index cardiac vagal tone. Physiological self-regulation was operationalized as the change in Vna from a baseline period of measurement to habituation. Decreases in Vna consistently related to habituation efficiency, operationalized as accumulated looking time (ALT), in all infants twice at 2 months and twice at 5 months; however, this relation was accounted for by infants who met an habituation criterion on each task. Among habituators, shorter lookers also had greater Vna suppression during habituation. Within-age and between-age suppression of vagal tone predicted ALT, but ALT did not predict suppression of vagal tone. Physiological self-regulation provided by the vagal system appears to play a role in information processing in infancy as indexed by habituation.     

Shape recognition in infancy: visual integration of sequential information

To investigate the integration of visual information across space and time, infants watched the contour of a shape being traced out by a moving point source of light and then viewed 2 objects: 1 with the shape they had just seen traced and 1 with a novel shape. In the first study, which varied the number of tracings (velocity about 16.7 cm/sec), 12-month-olds looked longer at the novel object in all conditions, indicating that they recognized the similarity between the alternative object and tracing of like contour. Study 2, which varied velocity (14.7 and 7.4 cm/sec), stimuli, and the number of tracings, provided evidence for the generalizability of these results but indicated that performance suffered at the slower speed. Studies 3 and 4 held velocity constant (14.7 cm/sec) while varying the size of the tracings and age of the infant: 12-month-olds, but not 6-month-olds, recognized figures in instances where it took up to 10 sec to complete a single tracing. Because it took so long to complete many of the tracings, central rather than purely retinal mechanisms appear to be involved in integrating shape in these situations.     

Eye movement analysis of information processing under different testing conditions

The study reported herein was designed to use eye movement data, collected during solution of complex figural analogies, to test the premise that enhanced feedback mechanisms and opportunities for dual coding of figural stimulus information result in the allocation of an increased percentage of information-processing resources to rule application activities. Subjects were given items from the Advanced Progressive Matrices under elaborated feedback, subject verbalization, or standard procedures. Results indicate that elaborative testing conditions, involving elaborated feedback or subject verbalization, enhance the rule-governed nature of information processing during inductive reasoning by augmenting feedback and dual coding.     

Toward a developmental model of child compliance: the role of emotion regulation in infancy

The present study examined the relation between early emotion regulation and later compliance. When infants were 5, 10, and 18 months of age, they participated in a frustration task. The degree to which they reacted negatively to the stimuli and the behaviors they used to regulate that response were coded. Baseline heart rate also was recorded and a measure of cardiac vagal tone (VNA) was derived. Several tasks (electrode placement, toy clean-up, and test situation) were administered to elicit compliance/noncompliance when the participants were 30 months of age. Results revealed that infants who demonstrated low levels of regulatory behavior were more likely to be noncompliant as toddlers. Several interaction effects suggested that the prediction to later noncompliance was also dependent upon the infants' level of reactivity. Cardiac vagal tone also was related to compliance but in a contradictory fashion. High VNA was related to noncompliance to toy clean-up, whereas low VNA was related to noncompliance to electrode placement. The data provide support for a developmental model of compliance that includes the ability to regulate emotional arousal.

Cognitive processing and developmental changes in finnish school students: Comparison between normal and language impaired (dysphasic) students

Course of cognitive development was investigated in a sample of normal school students (N=163) in the middle part of Finland by giving the students tests of four cognitive functions that were categorized according to the PASS theory of intelligence (planning, attention, simultaneous and successive processing). Subsequently, a group of students in special education (N=60, language impaired school students) was also studied for possible deviations in cognitive development. The age of the students varied from 7 to 19 years. Three main goals were (1) to study developmental trends of cognitive functions across three different age groups of school students and in two samples, (2) to identify distinct cognitive subgroups and profiles among the students, and, (3) to compare the cognitive profiles of normal and language impaired (dysphasic) students. First, in a cross-sectional design, it was seen linear cognitive trends for all PASS tasks, however so, that for the language impaired group the cognitive development was not as salient as for the normal students. Especially successive processing did not show developmental trend in the sample of language impaired (dysphasic) students. Secondly, a cluster analysis procedure following a factor analysis demonstrated two very distinct cognitive subgroups among the normal and dysphasic students. The subgroups in both separate samples differed from each other in successive and simultaneous processes. Additionally, the two subgroups of the normal students differed from each other also in planning. Thirdly, compared to the normal students, the dysphasic highly functioning subgroup did worse than normals in nonverbal successive ordering, but did better in verbal successive task. Contrary to expectations, the deviation was not on the verbal but instead on a nonverbal task. Need for extending PASS research into other types of learning problems (such as arithmetics, severe learning disability) is articulated. Pragmatically, observed minor differences in cognitive structure between the two student samples refer to differential remediation and skill training.     

Intermodal learning in infancy: learning on the basis of two kinds of invariant relations in audible and visible events

In this research, the development of intermodal perception in infancy was examined by using a new method, the intermodal learning method. 3-month-old infants were given the opportunity to learn a relation between 2 single film and soundtrack pairs through a 2-min familiarization period under 1 of 4 conditions. Films of naturalistic events were accompanied by a soundtrack that was (1) appropriate to the composition of the object and synchronous with its motions, (2) appropriate and nonsynchronous, (3) inappropriate and synchronous, or (4) inappropriate and nonsynchronous. A group of control subjects was familiarized with irrelevant films and soundtracks. Then all subjects were tested in a 2-choice intermodal preference test to determine under which familiarization conditions intermodal learning had occurred. Results indicated that only subjects who had been familiarized with appropriate and synchronous film and soundtrack pairs showed evidence of intermodal learning as compared with the performance of control subjects. Intermodal learning occurred on the basis of 2 kinds of invariant audio-visual relations, temporal synchrony, and temporal microstructure specifying the composition of the object. Intermodal learning did not occur through association on the basis of co-occurrence, nor did it occur when any incongruent audio-visual structure was present. These findings support an invariant-detection view of the development of intermodal perception.     

Understandingg in terms of information processing

Psychometric g, the general factor in individual differences in all types of tests and performances involving any mental ability, has much wider importance and implications than are encompassed by the field of psychometrics. It is argued that the nature of g must be understood in terms of information processes rather than in terms of the specific knowledge and skills that are seen in the content of conventional mental tests. The wide range of individual differences in g and disparities in the distribution of g in different subpopulations have important implications for understanding some of the major problems confronting public education.     

How the second screens change the way people interact and learn: the effects of second screen use on information processing

The use of a second screen can enhance information processing and the execution of search tasks within a given period. In this study, we examined the learner's attentional shift (AS) between two screens and controlled secondary tasks (STs) in the media multitasking setting and its effect on the learning process. In particular, we analyzed how cognitive and emotional learning effects can be explored depending on the role of this setting. A between-subject experiment was conducted with 69 participants (simultaneous vs. sequential use of a second screen in terms of open versus closed STs). The findings showed that there was a greater difference in emotional learning effects than in cognitive learning effects for participants who used a second screen. In terms of estimated emotional learning effects of media multitasking, participants engaged in sequential use demonstrated lower anxiety levels and higher competence beliefs during learning compared to participants who were engaged in simultaneous use. Moreover, an interaction effect occurred in the AS between the two screens and in controlled STs of recognition memory. These results indicate that attentional change and controlled STs are key predictors of learning effects in the media multitasking environment.     

Variable memory strategy use in children's adaptive intratask learning behavior: developmental changes and working memory influences in free recall

Variability in strategy use within single trials in free recall was analyzed longitudinally from second to fourth grades (ages 8-10 years). To control for practice effects another sample of fourth graders was included (age 10 years). Video analyses revealed that children employed different strategies when preparing for free recall. A gradual shift from labeling to cumulative rehearsal was present both with increasing age and across different list positions. Whereas cumulative rehearsal was frequent at early list positions, labeling was dominant at later list portions. Working memory capacity predicted the extent of cumulative rehearsal usage, which became more efficient with increasing age. Results are discussed in the context of the adaptive strategy choice model.     

Control processing vs. information processing in models of reading

The purpose of this paper is to highlight some important ways in which standard information-processing models of language, and specifically of reading, are deficient. It is proposed that the standard models do not provide an adequate framework for dealing with a number of central issues in reading. Their deficiencies are considered under four headings, (1) theoretical rigour, (2) the interaction of different levels of information during reading, (3) the parallel nature of much of human information processing, and (4) reading comprehension. The source of the problems is considered to be the view of information as an inert encoding and of information processing as a series of these encodings. A distinction is made between models which emphasize a flow of information and models which emphasize a flow of control. Production systems are proposed as examples of the latter type of model. Their use is seen as a qualitatively different approach to language processing which provides a solution to many of the problems inherent in the standard models.     

Different kinds of information affect word learning in the preschool years: the case of part-term learning

Two studies investigated how preschool children's interpretations of novel words as names for parts of objects were affected by 3 kinds of information: (a) whole object familiarity, (b) whole part juxtaposition, and (c) syntactic information indicating possession. Study 1 tested 3- to 4-year-olds and found that although there was evidence that all information affected children's part-term interpretations to some extent, they were most systematic when provided with 2 or more kinds of information. Study 2 adapted the procedure for use with 2.5-year-olds and found the same general pattern of results. Variations across studies were found that may reflect changes in how different kinds of information affect word learning with development.     

The architecture of human information processing: Empirical evidence

This article outlines a path analytic interpretation of data collected in light of a theoretical formulation of a dynamic model of memory, which provides a perspective on the human information processing system as a whole. The model of memory represents an attempt to integrate the relatively static models of memory structures with the more dynamic concepts underlying research on control and processing mechanisms. The outcomes of the study emphasise the role of relational knowledge (taxotomic subject matter structures), strategic knowledge (procedural algorithms) and empirical knowledge (based on first hand experience) in cognitive skill performance.     

Factor structure evidence for developmental levels of perceptual processing on the developmental test of visual-motor integration

Beery's Developmental Test of Visual-Motor Integration was individually administered to 193 school-age children. Test protocols were factor analyzed by a principal component solution. Four factors were obtained, indicating that the test does not measure a unitary dimension of perceptual-motor development, but rather four distinct levels or stages for the age range of children investigated. The structural features of the designs that make up the test were used to define the factors. It is argued that a more useful interpretation of performance on this test would be one that designates visualmotor processing in terms of levels, not age equivalents.     

Conflicting goals in self-evaluative information seeking: developmental and ability level analyses

Developmental changes in the resolution of conflicting goals involved in self-evaluation were examined in children entering second, fourth, and sixth grades representing high, medium, and low ability levels in arithmetic. Children completed a series of arithmetic tasks and were given an opportunity to evaluate themselves in terms of social comparison or autonomous comparison. As expected, overall, high-ability children engaged in the most self-evaluative information seeking, whereas low-ability children engaged in the least information seeking. Moreover, with increasing age, high-ability children were more likely to engage in autonomous comparison, whereas low- and medium-ability children maintained an interest in social comparison. In addition, greater interest in social comparison, particularly among older children, was associated with relative uncertainty about one's own ability but perceptions of ability as constant in others. The results are discussed in terms of strategies for balancing self-assessment with self-enhancement needs and the impact of such strategies for task mastery.
