Neuromuscular Control of Posture in the Infant and Child

This study explored the effects of vision and maturation on the characteristics of neuromuscular responses underlying balance control in both seated and standing children of five age groups (3½–5 months, 8–14 months, 2–3 years, 4–6 years, and 7–10 years). A platform was used to unexpectedly disturb the child’s balance in the anterior or posterior direction. Responses of the leg, trunk, and neck muscles were recorded using surface electromyograms.

Vision was not required for the activation of these responses in any of the age groups tested. However, comparison of muscle response latencies of standing children to posterior platform translation in the two visual conditions showed a significant reduction in latency for neck flexors in the 2- to 3-year-olds with vision removed and an increase in the total number of monosynaptic reflexes. No reduction in latency was found in the older age groups. The hypothesis of a shift from an early long latency visual dominance to a shorter latency proprioceptive one during childhood is discussed.

Postural control showed a cephalo-caudal developmental gradient with postural responses appearing first in the neck, then trunk, and finally, legs, as children developed from 3 to 14 months of age. A wide variety of response patterns was seen in the 3- to 5-month-olds, indicating that postural responses are not functional prior to experience with stabilizing the center of mass.     

Psychological Correlates to Myopia Compared to Hyperopia and Emmetropia

The relationship between some psychological factors and myopia (near-or shortsightedness) was explored. The hypotheses tested were to demonstrate a characteristic personality pattern of expressing anxiety and hostility. The myopes demonstrated, through the Rorschach Test, the manner of expressing anxiety covertly with a decrease in motor activity, while the hyperopes also demonstrated significant quantities of covert anxiety but with an increase in motor activity. The myopes and hyperopes, when each were compared to the normal-sighted control group, varied significantly less in the expression of non-specific anxiety and hostility. Thus, the findings supported the hypotheses.     

Ignorance, Instrumentality, Compensation, and the Problem of Evil

Some theodicists, skeptical theists, and friendly atheists agree that God-justifying reasons for permitting evils would have to have an instrumental structure: that is, the evils would have to be necessary to secure a great enough good or necessary to prevent some equally bad or worse evil. D.Z. Phillips contends that instrumental reasons could never justify anyone for causing or permitting horrendous evils and concludes that the God of Restricted Standard Theism does not exist—indeed, is a conceptual mistake. After considering Phillips’ and other objections in the neighborhood, I argue that the Expanded Theism of Christian theology does forward a God who ‘digs in’ and eternally answers for horrors.     

The influence of babbling patterns on the processing of speech

This study compared the preference of 27 British English- and 26 Welsh-learning infants for nonwords featuring consonants that occur with equal frequency in the input but that are produced either with equal frequency (Welsh) or with differing frequency (British English) in infant vocalizations. For the English infants a significant difference in looking times was related to the extent of production of the nonword consonants. The Welsh infants, who showed no production preference for either consonant, exhibited no such influence of production patterns on their response to the nonwords. The results are consistent with a previous study that suggested that pre-linguistic babbling helps shape the processing of input speech, serving as an articulatory filter that selectively makes production patterns more salient in the input.

Does rule recursion make melodies easier to reproduce? If not, what does?

Two experiments examined the effects of variations in melodic rule structure and rhythm upon the ability of musically sophisticated listeners to reproduce auditory patterns. These experiments were designed to evaluate different theoretical perspectives on auditory pattern perception and the role of rule structure in perceiving and remembering. Predictions of a coding model, which emphasizes the impact of rule recursion, were contrasted with those of an accent model, which emphasizes the relative timing of melodic and temporal accents. Effects of recursive (hierarchical) and nonrecursive (linear) rule arrangements were studied in contexts where pattern contour differences were controlled for. Rhythm was also varied. Measured pauses were inserted between certain tones to make a rhythm compatible or incompatible with melodic rule phrases. Experiment 1 showed that pattern simplicity was determined not by rule recursive codes, but by the number and timing of contour changes and melodic rule breaks. Experiment 2 examined additional effects of rhythm on listeners' response to rule recursion and melodic phrasing in melodies of equivalent contour. Although modest effects of rule recursion appeared, these effects were again outweighed by large performance differences due to the relative timing of changes in contour and melodic rule structure. Implications of the accent model for dynamic attending are discussed in the context of a new proposal involving temporal phasing of accents.     

Modality effects: Do they fall on deaf ears?

The present study tests the assumption of the PAS theory of echoic memory (Greene & Crowder, 1984) that the representation of acoustic features is necessary in producing modality effects. Performance by deaf subjects was compared to hearing subjects on serial and free-recall tasks with vocalizing and non-vocalizing conditions. For the serial tasks, typical modality and acoustic similarity effects were observed with hearing subjects, and no such effects were found with deaf subjects. However, for the free-recall task, modality effects were found for both deaf and hearing subjects. It is unlikely that phonological coding resulting from gestural cues mediates the modality effect, as phonological confusion errors for deaf and hearing subjects did not correlate with the size of this effect.
