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.     

The Tree of Life: Universal and Cultural Features of Folkbiological Taxonomies and Inductions

Two parallel studies were performed with members of very different cultures—industrialized American and traditional Itzaj-Mayan—to investigate potential universal and cultural features of folkbiological taxonomies and inductions. Specifically, we examined how individuals organize natural categories into taxonomies, and whether they readily use these taxonomies to make inductions about those categories. The results of the first study indicate that there is a cultural consensus both among Americans and the Itzaj in their taxonomies of local mammal species, and that these taxonomies resemble and depart from a corresponding scientific taxonomy in similar ways. However, cultural differences are also shown, such as a greater differentiation and more ecological considerations in Itzaj taxonomies. In a second study, Americans and the Itzaj used their taxonomies to guide similarity- and typicality-based inductions. These inductions converge and diverge crossculturally and regarding scientific inductions where their respective taxonomies do. These findings reveal some universal features of folkbiological inductions, but they also reveal some cultural features such as diversity-based inductions among Americans, and ecologically based inductions among the Itzaj. Overall, these studies suggest that while building folkbiological taxonomies and using them for folkbiological inductions is a universal competence of human cognition there are also important cultural constraints on that competence.

ANTECEDENT INFLUENCES ON BEHAVIOR DISORDERS

The influence of antecedent events on behavior disorders has been relatively understudied by applied behavior analysts. This lack of research may be due to a focus on consequences as determinants of behavior and a historical disagreement on a conceptual framework for describing and interpreting antecedent variables. We suggest that antecedent influences can be described using terms derived from basic behavioral principles and that their functional properties can be adequately interpreted as discriminative and establishing operations. A set of studies on assessment and treatment of behavior disorders was selected for review based on their relevance to the topic of antecedent events. These studies were categorized as focusing on assessment of antecedent events, antecedent treatments for behavior disorders maintained by either positive or negative reinforcement, and special cases of antecedent events in behavior disorders. Some directions for future research on antecedent influences in the analysis and treatment of behavior disorders are discussed.     

TOWARD A FUNCTIONAL ANALYSIS OF PRIVATE VERBAL SELF-REGULATION

We developed a methodology, derived from the theoretical literatures on rule-governed behavior and private events, to experimentally investigate the relationship between covert verbal self-regulation and nonverbal behavior. The methodology was designed to assess whether (a) nonverbal behavior was under the control of covert rules and (b) verbal reports of these rules were functionally equivalent to the covert rules that control nonverbal behavior. The research was conducted in the context of teaching shopping skills to persons with mild intellectual disabilities using a self-instruction training format. In Phase 1, 4 participants were successfully taught to perform shopping skills using overt and covert self-instructions. The self-instructions were then blocked under overt and covert self-instruction conditions, which resulted in a reversal of shopping skills to baseline levels. This indicated that the overt and covert self-instructions might be controlling responding. In Phase 2, we demonstrated that the self-instructions, when used as external directives, produced successful shopping with 3 other participants. By demonstrating that self-rules can produce correct responding when used as external directives, we were more confident that it was the self-instructions and not other verbal or nonverbal behavior that controlled responding under overt, covert, and blocking conditions in Phase 1.     

To "Correlate Psychology and Social Ethics": Gordon Allport and the First Course in American Personality Psychology

ABSTRACT This article explores the historical origins of what is widely regarded as the “first course in American personality psychology”: Gordon Allport's 1925 course entitled “Personality: Its Psychological and Social Aspects.” It argues that the professional focus and disciplinary context of Allport's course were much more complicated than is generally believed. Far from being a completely novel and distinctively psychological venture, Allport's course drew upon the moral concerns and the pedagogical and discursive practices of Harvard's Department of Social Ethics. Allport's course on “Personality” represented a subtle attempt to bring Victorian concerns with character development together with the newly emerging ideal of objectivity.     

LISTENING TO NICOTINE:

Abstract— In recent years, theoretical models of drug motivation and drug dependence have downplayed the role of withdrawal symptoms in the maintenance of addiction. During this same period, strong links between drug use and measures of negative affect have been uncovered in empirical research. In this article we examine these trends in the context of research on smoking. Evidence is presented from two recent studies on smoking relapse that highlight the intimate connection between withdrawal symptomatology and negative affect Specifically, these studies reveal that (a) single-occasion measures of withdrawal symptoms or other markers of physical dependence do not contribute incremental validity in preceding relapse relative to measures of negative affect (b) the trajectory of withdrawal symptoms is highly idiosyncratic, (c) exacerbations cannot be tightly coupled with pharmacological events. (d) the temporal dynamics of withdrawal reflect fluctuations in negative affect, and (e) differences in the trajectory of withdrawal symptoms index relapse vulnerability. We conclude that a broadened view of withdrawal recognizing its probable affective bases will enhance its explanatory power and suggest new treatment strategies.     

Visual information processing and intelligence

Measures of inspection time (IT) have robust, moderately-sized correlations with IQ-type test scores. However, the reason for the IT-IQ correlation is not understood. Although the original theory asserted that IT performance was based on a single parameter—essentially speed of visual processing—peculiarities of the task have afforded other interpretations of IT differences and the IT-IQ association. In the present report two new visual processing tasks, visual change detection (VCD) and visual movement detection (VMD) are found to be correlated at or above .4 with IT and with non-verbal scores from the Alice Heim 4 test of general intelligence. VCD and VMD, in common with IT, assess the stimulus duration that is required by subjects in order to make an accurate discrimination. VCD and VMD, however, require a broader attentional focus than IT and do not involve backward masking. Measures of contrast sensitivity, a difficult discrimination task in which stimuli are not time-limited, had near-to-zero correlations with other visual processing tasks and with IQ-type test scores. We tested the hypothesis that only the latent trait derived from the speeded visual processing tasks (rather than task-specific features) would correlate with cognitive ability, and this was supported. The present study adds weight to the view that it is the ability to make accurate discriminations in the face of limited stimulus time that causes IT to correlate with psychometric intelligence. The psychological correlates of VCD, in terms of neural circuits that detect “difference” suggest a new line of investigation into the psychobiological bases of human intelligence.
