New and Expanded Concepts in Neurophysiology,Psychology, and Sociology Complementary to Llorens' Developmental Theory: Achieving Growth and Development through Occupation for Neonatal Infants and their Families

ABSTRACT

Introduction: This issue expands the Llorens’ Developmental Theory of Occupational Therapy. Llorens drew from multiple theorists from the disciplines of sociology, neurophysiology, biology, ecology, psychology, occupational science, and psychodynamics to provide the profession of occupational therapy with a unified theory to facilitate growth and development for people of all ages—from infancy to old age.

Purpose: The purpose of this issue is to analyze, synthesize, and evaluate the continued relevance of Llorens' theory. In addition, the author evaluates, recommends, and applies updated theoretical premises in the realms of psychodynamics, neurophysiology, contextual ecology, and cognitive science that reflect the relevance of occupational therapy practice for infants and their families in the neonatal intensive care unit.

New Psychological Elements: Through the appropriate use of purposeful occupational activity and affective object relationships, the expanded Developmental Theory of Occupational Therapy provides a unified theory of occupation enablement as intrinsic spatiotemporal adaptation and as extrinsic socio ? cultural and physically contextual occupational adaptation to achieve growth and development across the lifespan.     

Motion-induced blindness measured objectively

During central fixation, a moving pattern of nontargets induces repeated temporary blindness to even salient peripheral targets: motion-induced blindness (MIB). Hitherto, behavioral measures of MIB have relied on subjective judgments. Here, we offer an objective alternative that builds on earlier findings regarding the effects of MIB on the detectability of physical target offsets. We propose a small modification of regular MIB displays: Following a variable duration (lead time), one of the targets is physically removed. Subjects are to respond immediately afterward. We hypothesize that illusory target offsets, caused by MIB, are mistaken for physical target offsets and that errors should thus increase with lead time. Indeed, for both nonsalient and salient targets, we found that detection accuracy for physical target offsets dramatically decreased with lead time. We conclude that target offset detection accuracy is a valid objective measure of MIB. With our method, effects of guessing are minimal, and the fitting of psychometric functions is straightforward. In principle, a staircase extension—for more efficient data collection—is also possible.     

Is obesity treated like a contagious disease?

The behavioral avoidance of people with obesity is well documented, but its psychological basis is poorly understood. Based upon a disease avoidance account of stigmatization, we tested whether a person with obesity triggers equivalent self-reported emotional and avoidant-based responses as a contagious disease (i.e., influenza). Two hundred and sixty-four participants rated images depicting real disease signs (i.e., person with influenza), false alarms (i.e., person with obesity), person with facial bruising (i.e., negative control), and a healthy control for induced emotion and willingness for contact along increasing levels of physical proximity. Consistent with our prediction, as the prospect for contact became more intimate, self-reported avoidance was equivalent in the influenza and obese target conditions, with both significantly exceeding reactions to the negative and healthy controls. In addition, participants reported greatest levels of disgust toward the obese and influenza target conditions. These results are consistent with an evolved predisposition to avoid individuals with disease signs. Implicit avoidance occurs even when participants know explicitly that such signs—here, obese body form—result from a noncontagious condition. Our findings provide important evidence for a disease avoidance explanation of the stigmatization of people with obesity.     

De Finetti’s No-Dutch-Book Criterion for Gödel logic

We extend de Finetti’s No-Dutch-Book Criterion to Gödel infinite-valued propositional logic.     

Minority influence: the role of ambivalence toward the source

According to literature on social influence, a minority source may indirectly influence group members by fostering ambivalent reactions. Two studies were carried out in order to provide empirical support for this theoretical assumption. In Study 1 participants (n = 133), were exposed to a counter‐attitudinal minority message and ambivalence was manipulated by facilitating the accessibility of either ambivalent (positive and negative) or univalent (positive or negative) thoughts toward the source. We predicted and found more indirect influence in ambivalent condition than in univalent conditions. No effect of ambivalence on direct influence was found. In Study 2 (n = 127), ambivalence was measured and two possible antecedents of ambivalence, consistency of the minority and personal relevance of the topic for participants, were taken into account. Findings suggest that ambivalence mediates the effects of the two factors on indirect influence. In sum, these studies provide evidence of the importance of ambivalence in minority influence context, an early assumption that was still lacking in strong empirical support.

Intrapsychic-Interpsychic

The ‘interpsychic’ is an extended psychic dimension, regarding the joint functioning and reciprocal influences of two minds. The concepts of ‘subjectivity’ and ‘person’ can be included in the ‘interpsychic’. They can also overlap with each other, and sometimes all three can overlap together, but they do not necessarily coincide. In the different contemporary perspectives, how can we modify the intrapsychic ‘through’ (and ‘with’ and ‘by’) the interpsychic? Presenting four clinical vignettes, the author progressively moves from the theoretical positions that emphasise the exploration and the elaboration of the intrapsychic mainly through the intrapsychic, to the positions that emphasise the same operations mainly through the interpsychic. The last part of the paper deals with the technical use of the interpsychic dimension: the analytic dialogue, when interpsychically experienced (from inside), gains a new, more specific effectiveness, first in containing and then in symbolising. In an intense mental ‘cohabitation’ inside the analytic working pair, it is very often clearly experienced as ‘true’ (as in dreams).     

Facial Expressions and the Ability to Recognize Emotions from the Eyes or Mouth: A Comparison Between Children and Adults

The authors sought to contribute to the literature on the ability to recognize anger, happiness, fear, surprise, sadness, disgust, and neutral emotions from facial information. They aimed to investigate if—regardless of age—this pattern changes. More specifically, the present study aimed to compare the difference between the performance of adults and 6- to 7-year-old children in detecting emotions from the whole face and a specific face region, namely the eyes and mouth. The findings seem to indicate that, for both groups, recognizing disgust, happiness, and surprise is facilitated when pictures represent the whole face. However, with regard to a specific region, a prevalence for children was not found between the eyes and mouth. Meanwhile, for adults, would seem to detect a greater role of the eye region. Finally, regarding the differences in the performance of emotions recognition, adults are better only in a few cases, whereas children are better in recognizing anger from the mouth.     

Behavioral Problems in Taiwanese Children of Adolescent and Adult Mothers

The purpose of this study was to estimate child behavioral problems over time and determine gender differences in behavioral problems between children born to adolescent and adult mothers in Taiwan. The consistency between parent’s and teacher’s reports was also examined. Secondary analysis of a longitudinal dataset from Taiwan was conducted. A matched sample of 107 children born to adolescent mothers and 111 children born to adult mothers were recruited. Child behavioral problems were assessed by parents at Time 1 (1^st and 2^nd grades) and by teachers at both Time 1 and Time 2 (5^th and 6^th grades). Generalized estimating equations and paired t-test were used. At Time 1, compared to children of adult mothers, children of adolescent mothers had had more behavioral problems by both parental and teacher’s reports. Both parents and teachers reported that boys had more behavioral problems than girls. Moreover, according to teacher reports, children of adolescent mothers and boys had more behavioral problems and these differences persisted over time, even controlling for sociodemographic characteristics. In addition, parents reported higher scores of behavioral problems than teachers. In conclusion, child behavioral problems in Taiwan are associated with maternal age at child birth and child’s gender. Interventions may profitably focus on determining the mechanisms that lead to behavior problems in children of adolescent mothers, and/or reducing adolescent pregnancy as a way of decreasing child behavioral problems. Screening and preventive interventions for child behavior problems may need to be gender-specific.
