Infant clinical assessment procedure: Its applications for diagnosis and treatment in the second and third year

This article reports on some clinical applications in the 9 to 30 month age range of a new structured paradigm. The Infant Clinical Assessment Procedure (ICAP) is not a test, but an assessment technique. It is particularly aimed at the evaluation and ongoing monitoring of problems in the emotional development of infants. Its eight episodes represent a wide array of effective, social, and cognitive stimuli. The primary focus of these episodes is on the infant, with the exception of the mother-infant task that specifically gauges the mother-infant ralationship. It is suggested through case vignettes that the ICAP may be useful for the documentation of the efficacy of treatment.     

Non-organic failure-to-thrive: Deprivation or distortion?

Infants diagnosed non-organic failure-to-thrive (NOFT) show arrested physical development. The cause of the growth delay and of the accompanying behavioral anomalies is not known, but generally is attributed to maternal deprivation. This study investigated the hypothesis that family hostility was also a contributing factor. NOFT families were compared with maltreating and adequate families and found to be larger and more intact, but characterized by extremely distressed interpersonal relationships and family violence. This result was interpreted as suggesting that NOFT resulted from the stress of both insufficient and inappropriate treatment of the infant. The source of the stress was observed to include the entire family, the members of which were displaying other psychosomatic manifestations of stress.     

Mental Arithmetic: A Componential Analysis of Speed-of-Processing Across Monolingual,Weak Bilingual,and Strong Bilingual Adults

Two experiments compared rates of solving simple and complex addition and multiplication problems in groups of speakers of French or English in Experiment 1 (n = 35) and Spanish or English in Experiment 2 (n = 84). Subjects were divided into groups of English unilinguals, weak bilinguals, and strong bilinguals according to their performance on a naming task. In both experiments, simple problems consisted of two single-digit numbers. At least three single-digit numbers were used for complex problems in Experiment 1 and double-digit numbers in Experiment 2. Mean solution times, particularly for complex problems, were lowest for the monolingual group, followed in turn by the weak bilingual and strong bilingual groups, but these differences were not statistically reliable in either experiment. In Experiment 2, however, componential analyses of solution times indicated that strong bilingual subjects were slower at executing the carry operation when solving complex problems, relative to the two remaining groups. Results were interpreted in terms of the relationship between bilingualism and the representation and processing of numerical information.

The Organization of Extrinsic Neurons and Their Implications in the Functional Roles of the Mushroom Bodies in Drosophila melanogaster Meigen

Although the importance of the Drosophila mushroom body in olfactory learning and memory has been stressed, virtually nothing is known about the brain regions to which it is connected. Using Golgi and GAL4–UAS techniques, we performed the first systematic attempt to reveal the anatomy of its extrinsic neurons. A novel presynaptic reporter construct, UAS-neuronal synaptobrevin–green fluorescent protein (n-syb–GFP), was used to reveal the direction of information in the GAL4-labeled neurons. Our results showed that the main target of the output neurons from the mushroom body lobes is the anterior part of the inferior medial, superior medial, and superior lateral protocerebrum. The lobes also receive afferents from these neuropils. The lack of major output projections directly to the deutocerebrum’s premotor pathways discourages the view that the role of the mushroom body may be that of an immediate modifier of behavior. Our data, as well as a critical evaluation of the literature, suggest that the mushroom body may not by itself be a “center” for learning and memory, but that it can equally be considered as a preprocessor of olfactory signals en route to “higher” protocerebral regions.     

Impacting Awareness of Child Abuse through a Performing Arts Project

A folk opera, AVE, explored issues of child abuse, sexual assault and violence through the character of Mary Magdelene. Using indigenous religious folklore images, Magdelene is befriended by Jesus's mother and healed of her childhood wound through a religious conversion. Six hundred secondary students attended three daytime performances and 486 returned a Likert‐scaled questionnaire. Results indicated most students perceived abuse as a personally relevant, real social problem, with felt relevance increasing with age. Significant trends supported initial expectations with an increase in community and personal awareness of child abuse/sexual assault and an increase in personal and community interest in helping others. Community risk factors contributing to denial of abuse were explored. More Hispanics responded positively to the sense of benefit. Findings suggest that performing arts can help increase awareness of child abuse as well as help stimulate personal and community interest in helping. This benefit increases with teacher discussion and age.     

Circle size and diameter tilt: A new look at integrality and separability

In six experiments using the speeded classification paradigm, we provide evidence that the ostensibly “separable” dimensions of size and orientation can produce patterns of either separability or asymmetric configurality, depending on the spatial arrangement of the stimuli. In all experiments, subjects classified large or small circles contairting a single line in one of two possible orientations. When the line touched the circle’s perimeter, thereby defining the diameter of the circle (Experiments 1–4), asymmetric configurality obtained: Variations in size interfered with classification by orientation, but variations in orientation did not interfere with classification by size, and redundancy gain was weak or absent. When the lines fell completely within (i.e., did not touch) the circles (Experiments 5 and 6), the results were consistent with separability: There was neither redundancy gain nor interference. Taken together, the results add to the growing body of evidence that classification of specific dimensional pairs as separable or integral may be less feasible than identifying the more general conditions that increase or decrease the psychological salience of dimensional structures and facilitate or interfere with selection of optimal processing strategies.     

Fixation-point offsets reduce the latency of saccades to acoustic targets

If an observer’s fixation point is extinguished just prior to the onset of a peripheral target, the latency to saccade to that target is reduced. We show that this "gap effect" is not specific to visual targets. Observers made saccades to a light flash or to a white-noise burst. A warning tone was presented on every trial to control for the possible warning effect of the fixation-point offset. For both target modalities, saccade latencies were significantly reduced when the fixation point was extinguished 200 msec prior to the target onset. Implications of this outcome for interpretations of the gap effect are considered. It is argued that the presence of a gap effect for tones, in conjunction with previous findings, is consistent with the hypothesis that the gap effect is produced by a facilitation of premotor processes in the superior colliculus.
