Comparison of Allocations by Individuals and Interacting Groups in an Escalation of Commitment Situation1

In this study, individuals and interacting 3‐person groups were asked to make a series of allocation decisions using a modified version of the A&S decision case (Staw, 1976). Based on the choice‐shift effect, it was hypothesized that groups would allocate more to a failing course of action than would individuals, and that these differences would emerge only after repeated sequential decisions. Both hypotheses were supported. These findings suggest that processes unique to groups account for the greater allocations of groups, relative to individuals in escalation situations. The implications of these findings in applied settings are discussed.     

Relations between approaches to studying and note-taking behaviour in lectures

Copies of notes taken during a lecture were obtained from first-year psychology students, and the relations examined between measures derived from these (the number of points recorded, the number of words written, and the number of words per point) and a number of variables measuring personality and approach to studying. Three variables were found to be related to the measures derived from the notes: older students, those scoring high on strategic learning (strategy component) and those scoring high on surface learning (motivational component), both measured by questions derived from Biggs (1979), produced longer notes and recorded more of the important points in the lecture. The results suggest that relations between approaches to studying and specific study behaviour are not straightforward and require more detailed investigation.     

Simulating the variability of actual outcomes

A method is described for simulating the variability of outcomes encountered in a variety of settings. Outcome values falling within a specified range are randomly generated and presented across subjects and trials, so that, over time, the average values seen by all subjects in a condition are the same. Randomly varying reinforcement dimensions (such as magnitude) over trials for each subject is recommended to enhance both the internal and the external validity of laboratory results. In addition, it can be used to study the effects of the variability or uncertainty of outcome dimensions such as magnitude and duration in investigations of behaviors such as matching, melioration, and behavioral momentum.     

Psychophysics in the field: Perception and memory for labor pain

Separate groups of women estimated the painfulness of labor contractions either immediately (perceptual judgments) or at time intervals varying from 8 to 48 h after their completion (memorial judgments). The pain judgments of individual uterine contractions were related functionally to the biometrically measured magnitude of these contractions. Perceived and remembered painful sensations were related to referent intensities by power functions governed, as a rule, by exponents greater than unity. Exponents for the memory functions were consistently greater than those for the perceptual functions. Psychophysics done in the field can help decide theoretical issues in addition to providing useful practical information.     

Construction of monadic three-valued Łukasiewicz algebras

The notion of monadic three-valued ukasiewicz algebras was introduced by L. Monteiro ([12], [14]) as a generalization of monadic Boolean algebras. A. Monteiro ([9], [10]) and later L. Monteiro and L. Gonzalez Coppola [17] obtained a method for the construction of a three-valued ukasiewicz algebra from a monadic Boolea algebra. In this note we give the construction of a monadic three-valued ukasiewicz algebra from a Boolean algebra B where we have defined two quantification operations and ^* such that ^*x=^*x (where ^*x=-^*-x). In this case we shall say that and ^* commutes. If B is finite and is an existential quantifier over B, we shall show how to obtain all the existential quantifiers ^* which commute with .Taking into account R. Mayet [3] we also construct a monadic three-valued ukasiewicz algebra from a monadic Boolean algebra B and a monadic ideal I of B. The most essential results of the present paper will be submitted to the XXXIX Annual Meeting of the Unión Matemática Argentina (October 1989, Rosario, Argentina).     

Evaluating the filial behaviour scale across three cultural groups using exploratory structural equation modelling

Filial piety is a Confucian concept that guides how children treat and take care of their parents. The Filial Behaviour Scale (FBS) is a 25-item instrument developed in the Chinese context measuring behavioural manifestations of filial piety. Although the components of filial piety have been found to be relevant across cultures, little research has investigated the psychometric properties of the FBS in other cultural contexts. The present study evaluated the factor structure, internal consistency, measurement invariance and construct validity of the FBS across three cultural groups: the United States, Italy and Malaysia. Participants were 1090 emerging adults (67% females; M_age = 21.29 years, SD = 1.97; White Americans: n = 455, White Italians: n = 428, Malays: n = 328). A two-factor structure emerged across groups: Obedience/Obligation (behaviours showing obedience and obligation towards parents) and Relationship (behaviours expressing affection and promoting positive parent–child relationships). The two factors demonstrated adequate internal consistency, full configural, partial metric and partial scalar invariance, as well as unique associations with depressive symptoms and parent–child relationships across groups. These findings yielded a more nuanced understanding of filial behaviour and supported the utility of a two-factor FBS among emerging adults in various cultural contexts.     

Metacognitive Interpersonal Therapy Improves Adherence to Antiretroviral Therapies in a Man with a Severe Personality Disorder: A Case Report

Treatment adherence by patients with HIV ensures they gain the full benefit of antiretroviral medications and extend their lives. One problem which may contribute to poor adherence is deficits in metacognition or the capacity to make sense of mental states. In particular, persons who struggle to notice and think about their thoughts and feelings may be less able to direct their own recovery by taking advantage of effective treatments. This raises the possibility that treatments which lead to improved metacognitive function may enhance treatment adherence. We describe the case of a man in an advanced stage of AIDS with Kaposi’s sarcoma. The patient was treated with Metacognitive Interpersonal Therapy combined with psychoeducation about pharmacological treatment for HIV. Primary medical outcomes were suppression of viral load, increase of CD4 count and control of AIDS related conditions such as Kaposi’s sarcoma. The primary psychological outcome was reduction of personality disorders criteria. The patient was able to understand what led him to discontinue medication and then later regain full adherence. He achieved suppression of viral load and restore of CD4 count. As regard severity of personality disorder, he achieved reliable change. Interventions such as Metacognitive Interpersonal Therapy may assist patients with HIV to gain the metacognitive capacities to make sense of their medical and psychological challenges and adhere to antiretroviral therapies leading to enhanced levels of health. Future studies are needed to explore these findings in larger controlled studies.     

The Associations between Perceived Maternal Psychological Control and Academic Performance and Academic Self-Concept in Chinese Adolescents: The Mediating Role of Basic Psychological Needs

This study examined the associations between perceived maternal psychological control and adolescent academic functioning in terms of academic performance and academic self-concept. The study also tested the possible mediating role of basic psychological needs to investigate how parental psychological control is related to child academic functioning. A sample of Chinese adolescents (N?=?338) completed a self-administered questionnaire on maternal psychological control, academic self-concept, academic performance and basic psychological needs satisfaction. Structural equation modeling was used for data analyses. Findings of this study revealed that Chinese adolescents’ perceptions of maternal psychological control were associated with their academic self-concept, and furthermore this association was mediated by adolescents’ basic psychological needs satisfaction on autonomy, relatedness and competence. Theoretical and practical implications, as well as future research directions were discussed.
