A functional analytic approach to computer-interactive mathematics

Following a pretest, 11 participants who were naive with regard to various algebraic and trigonometric transformations received an introductory lecture regarding the fundamentals of the rectangular coordinate system. Following the lecture, they took part in a computer-interactive matching-to-sample procedure in which they received training on particular formula-to-formula and formula-to-graph relations as these formulas pertain to reflections and vertical and horizontal shifts. In training A-B, standard formulas served as samples and factored formulas served as comparisons. In training B-C, factored formulas served as samples and graphs served as comparisons. Subsequently, the program assessed for mutually entailed B-A and C-B relations as well as combinatorially entailed C-A and A-C relations. After all participants demonstrated mutual entailment and combinatorial entailment, we employed a test of novel relations to assess 40 different and complex variations of the original training formulas and their respective graphs. Six of 10 participants who completed training demonstrated perfect or near-perfect performance in identifying novel formula-to-graph relations. Three of the 4 participants who made more than three incorrect responses during the assessment of novel relations showed some commonality among their error patterns. Derived transfer of stimulus control using mathematical relations is discussed.     

Nursing and psychological treatments

Presents a comment on "Psychological Treatments" by D. H. Barlow. In his article, Barlow pointed to the need "to solidify the identification of psychology as a health care profession" by changing the terminology of practice in the health care context from psychotherapy to psychological treatments and suggested that the only persons qualified to carry out such interventions are doctoral-level psychologists. Unfortunately, there was no discussion of the health care professionals who already provide psychological treatments in health care settings and their contribution to the evidence base supporting such treatment. The authors find several aspects of the article to be problematic. Overall, the authors feel that suggesting that psychology should claim treatment of psychological disorders and psychological components of physical disorders in health care settings as exclusively its own domain ignores the research and clinical contributions of others.     

Global Economy,Justice and Sustainability

Although this paper attends to some extent to the question whether the global economy promotes or impedes either justice or sustainability, its main focus is on the relationship between justice and sustainability. Whilst sustainability itself as a normative goal is about sustaining inter alia justice, justice itself requires intergenerationally the sustaining of the conditions of a good life for all. At the heart of this is a conception of justice as realising the basic rights of all–in contrast to a more demanding distributive principle or a less demanding principle of not violating the liberty rights or other basic rights of others. Although Pogge’s analysis that the global economy causes harm by failing to realise basic rights is seen as a useful challenge to common libertarian assumptions, the acceptance of other positive correlative duties, following Shue, is advocated. Insofar as the global economy fails to realise basic justice, the question is ‘how far can it realistically be changed?’ and this is a function partly of the moral attitudes of individuals at large.     

The Role of Reproductive Strategies in Academic Attainment

Since there is a tradeoff between prolongedformal education and early reproduction, education canbe construed as a long-term reproductive tactic. Thisreproductive strategies approach was tested by looking at relationships between sociosexuality (SOI)and parental investment (parental income, number ofsiblings, parental divorce, number of step siblings,birth intervals, birth order, closeness to parents) and GPA of 139 White students at a privatecollege. Parental investment was reduced to threefactors (Family Composition, Family Security, andMarital Instability), the last of which was negativelycorrelated with GPA and positively correlated with SOI.SOI was a much stronger (negative) predictor of GPA inwomen, but not men, than ACT was. Results support thereproductive strategies approach and imply that prediction of academic difficulty (and genderdifferences therein) must confront reproductiveissues.     

Sequential analysis of visual habituation in preschool children

The study breaks down the data from a preschool (mean age of students, 63 months) visual habituation experiment using a second-by-second analysis of the entire process, including fixation time and onsets for habituation and recovery trials and for each intertrial interval. The results parallel those suggested by Cohen, DeLoach, and Rissman (Child Development, 1975, 46, 611–617), for infants and are described using a two-process model of visual attention.     

Relations between nutrition and cognitive performance in Egyptian toddlers

Two relatively unexplored questions--which specific components of chronic mild child malnutrition are associated with specific behavioral and cognitive deficits and do psychosocial child rearing factors moderate the nutrition-development relationship?--were investigated in a longitudinal study involving 153 toddlers from the Egyptian village of Kalama. Beginning at study entry at age 18 months and continuing until 30 months, food intake information was obtained for 2 consecutive days each month. During the same period, researchers visited the homes twice a month to observe both toddler behavior and caregiver styles. Finally, standardized infant development tests were administered at 24 months and 30 minutes and the capacity for exploratory, symbolic play was assessed. Specific components of nutritional intake at 18-23 months of age were confirmed to be uniquely related to specific developmental outcomes at 24 months of age. Changes in toddler intake from 18-30 months also predicted 30-month cognitive performance. At 24 months, general mental competence was associated positively with fat intake, total kilocalories, and total protein intake while symbolic play capacity was related only to total protein intake. Significant increases in predictive variance occurred when the model was expanded to encompass caregiver behaviors as well as nutritional factors. For example, when nonverbal response to child vocalizations was used as the environmental measure, there was evidence of both coactive and synergistic interactions for comparisons involving cognitive development indicators. For symbolic play, an increase in predictive variance was found when the model included the multiplicative interaction of animal kilocalories by nonverbal response to vocalizations. Also observed was a buffering effect against poor psychosocial rearing conditions given the presence of adequate nutritional intake. These findings suggest the feasibility of multidimensional risk profiles, the provision of specific nutrients targeted at specific deficits, and multidisciplinary interventions.     

Affect in early memories of borderline patients

Psychoanalytically oriented observers using the framework of object relations theory noted that patients with borderline personality organization manifest serious pathology in their capacity to use internalized imagery to cope with the vicissitudes of separation-individuation. This study examined one source of such imagery, the affect associated with a specific sample of early memories, including the earliest recollections of parents. Patients with borderline personality disorder were compared with paranoid schizophrenics and patients with neurotic character pathology. Forty-five outpatients, 15 in each group, participated in the study. It was found that borderline patients had significantly fewer positively toned early memories than neurotics or paranoid schizophrenics. Only the neurotic group, had a majority of affectively positive memories. The results are generally consistent with object relations theories of borderline psychopathology.     

Newborn behavioral observations system in rural Pakistan: A feasibility and acceptability study

The Newborn Behavioral Observations (NBO) system is a relationship-based tool that helps parents recognize their infant's competencies and learn their behavioral cues, with the goals of enhancing parental responsiveness and satisfaction in the infant-parent relationship. In our study, a pediatrician integrated the NBO into 44 pediatric health care visits of infants in rural Pakistan villages, under the remote guidance of two U.S.-based child psychiatrists. A clinician then gave the mothers a survey about their experience of the NBO and found that the mothers were highly satisfied, reporting greater appreciation of their infant's strengths, greater understanding of their infant's behavioral cues, stronger attachment to their infant, and greater self-confidence as a mother. In their consideration of these results, the authors explore cultural reasons for the mothers’ responses and generate hypotheses to inform an outcome study of a similar intervention. This was a feasibility and acceptability study and was not randomized, had no control group, and did not use objective measures of outcome.     

Reflections on the process of psychotherapeutic change as applied to medical situations

This article takes the basic ideas on the process of changing implicit knowledge put forward in this special issue, and extends them beyond psychotherapy to include other therapeutic relationships that occur in medicine. One vignette, from an encounter between a medical student and a dying patient, illustrates how a “moment of meeting” changes the student as well as the patient. The second shows how therapeutic interventions for new mothers with their newborn infants involve “moments of meeting” that alter the mother's implicit knowledge of her baby and of herself as a mother. © 1998 Michigan Association for Infant Mental Health
