Clinical,developmental and social aspects of infant crying and colic

Persistent unexplained infant crying in the first few months is a common source of distress for parents and is costly for the health services. The aim was to assess the merits of developmental and social conceptualizations of this phenomenon, compared to the clinical approach as represented by the concept of colic. From a community sample of 530 infants, 67 who met the ‘rule of threes’ definition of colic by fussing and crying for 3 or more hours per day at 4-5 weeks of age were chosen. To avoid confusion, these infants were called ‘persistent criers’. Groups of ‘evening criers’ (N = 38) and ‘moderate cries’ (N = 55) were also selected. These 160 infants were assessed by researcher measures of their consolability and by maternal diary measures of their amounts of fussing, crying and colic behaviour when 5-6 weeks old. The persistent and evening criers cried more than the moderate criers. However, irritable, ‘fussy’ behaviour was the predominant form of distress for all three groups of infants. Colic bouts–defined as ‘bouts of intense, unsoothable crying and other behaviour, perhaps due to stomach or bowel pain’–were rare even among the persistent criers and only 7% of these infants were found to be inconsolable. The results support growing evidence that normal infant developmental processes are central to this phenomenon. In addition, social interactions between infants and parents, and parental subjective variables, appear to be involved. Colic was distinguished as a rare and separate form of distress by the infants' mothers. Further evidence needs to determine whether colic is a distinct clinical phenomenon or an extreme degree of normal distress interpreted within a western cultural framework.     

Counselling problem drinkers: The realm of specialists. Alcoholics Anonymous or generic counsellors?

A study was carried out to investigate counsellors' attitudes and experiences in working with people with drinking problems and counsellors' understanding of Alcoholics Anonymous as a helping agent. Ninety-four counsellors responded to a questionnaire about their work with people with drinking problems and their knowledge of AA. Generic counsellors tended not to feel competent working with clients with alcohol problems. Feelings of competence increased with greater experience of the client group and, to a lesser extent, with more hours of specialist training. It was found that counsellors whose intake of alcohol amounted to more than eight units per week were less likely to take on clients with alcohol problems than were those who drank less. Counsellors usually had some knowledge of AA but had little understanding of the 12-step programme that forms the basis of recovery for alcoholics as described by AA. They were, however, in favour of clients attending AA as an adjunct to individual counselling     

Myths as Instructions from Ancestors: The Example of Oedipus

The growing interest in dual-inheritance models of human evolution has focused attention on culture as a means by which ancestors transmitted acquired phenotypic characteristics to their descendants. The ability of cultural behaviors to be repeatedly transmitted from ancestors to descendants enables individuals to influence their descendant-leaving success over many more generations than are usually coclusive fitness. This essay proposes that traditional stories, or myths, can be seen as a way in which ancestors influence their descendant-leaving success by influencing the behavior of many generations of their descendants. The myth of Oedipus is used as an example of a traditional story aimed at promoting proper behavior and cooperation among kin. This interpretation of the Oedipus myth is contrasted with Freudian and structuralist interpretations.     

Measuring the effect of multiple eye fixations on memory for visual attributes.

Because of limited peripheral vision, many visual tasks depend on multiple eye fixations. Good performance in such tasks demonstrates that some memory must survive from one fixation to the next. One factor that must influence performance is the degree to which multiple eye fixations interfere with the critical memories. In the present study, the amount of interference was measured by comparing visual discriminations based on multiple fixations to visual discriminations based on a single fixation. The procedure resembled partial report, but used a discrimination measure. In the prototype study, two lines were presented, followed by a single line and a cue. The cue pointed toward one of the positions of the first two lines. Observers were required to judge if the single line in the second display was longer or shorter than the cued line of the first display. These judgments were used to estimate a length threshold. The critical manipulation was to instruct observers either to maintain fixation between the lines of the first display or to fixate each line in sequence. The results showed an advantage for multiple fixations despite the intervening eye movements. In fact, thresholds for the multiple-fixation condition were nearly as good as those in a control condition where the lines were foveally viewed without eye movements. Thus, eye movements had little or no interfering effect in this task. Additional studies generalized the procedure and the stimuli. In conclusion, information about a variety of size and shape attributes was remembered with essentially no interference across eye fixations.     

Social processing errors among paranoid personalities

The present study tested clinical hypotheses about the social processing attributes of paranoid personalities (PP). Eighteen PPs and 18 normal controls (NC) viewed standardized role plays (Dodge, 1986) in which a provocation occurred but the protagonist's intention varied (i.e., ambiguous, accidental, hostile, or prosocial). Subjects identified the intention behind the action and then chose a response to that action (e.g., ignore what he did). The results indicated that PPs and NCs did not differ on intentioncue detection when the intention was clear, but PPs had a significantly higher rate of misreading ambiguous situations. Furthermore, when intentions were ambiguous, PPs were more likely than NCs to identify them as hostile intentions. Finally, PPs' reactions to the vignettes were different from normal controls' when the perceived intention was either prosocial or accidential. PPs were more likely to respond with anger and less likely to ignore the event, compared to NCs. These data provide initial support for clinical notions about the aberrant social processing of paranoid personalities.     

Holistic processes in the perception and transformation of disoriented figures

Two experiments tested whether mental rotation of complex, hierarchical stimuli occurs holistically or separately at global and local levels of structure. Large (global) letters were constructed from spatial arrangements of small (local) letters. Reflection conditions (normal vs. reflected) were produced by varying the two levels independently. The task was structured so that subjects could rotate one level of the stimulus in some conditions but had to rotate both levels in other conditions. Experiment 1 showed that rotation rate was not affected by the number of levels that had to be rotated to make a reflection decision. This result implies that the rotation of global and local levels occurred together rather than sequentially. Experiment 2 showed that the rotation of the two levels was holistic as opposed to parallel and independent. The results also demonstrate that global information is processed faster than local information regardless of whether or not a rotation is performed. These findings are discussed in relation to theories of mental rotation and global precedence.     

CHILDREN'S THINKING IN BOTSWANA: PIAGET TASKS EXAMINED*

This Piaget replication study was done in Botswana. Six tasks were completed by 554 primary school children from urban, rural, and traditional village environments. Conservation of number, length, mass and weight, seriation and classification exercises were carried out using materials commonly found in the culture. Previous studies by other investigators have compared schooled and unschooled subjects in other African countries, but often unschooled subjects were from rural areas, so the environmental effects could not be isolated. In this study comparisons were made between students in the three environments, between age groups, and between male and female subjects. Urban children completed tasks at an earlier age than those from other environments. In general, the results are similar to findings from other African countries.     

Inability to wink an eye and eye dominance.

Data from 56 subjects in Grades 4 to 12 only able to wink one eye indicated that the non-winking eye was used as the dominant one in tests on monocular and binocular sighting.     

Boyle's corpuscular hypothesis and Locke's primary-secondary quality distinction

Locke denied that ideas of secondary qualities resemble their causes. It has been suggested that Locke denied this because he accepted a mechanical corpuscular hypothesis about the constitution of objects. This paper shows that this and other usual explanations of Locke's denial are mistaken. Further, it suggests an alternative relationship between the scientific account and Locke's philosophical views, and finally it provides Locke's real justification for his claim that ideas of secondary qualities do not resemble their causes.This paper was prepared with the assistance of a SUNY UAC/JAC Faculty Research Fellowship.
