The cost of a strategy

Abstract

Experiment 1 demonstrated a new kind of dual-task interference effect. The primary task was a speeded left-right discrimination of stimulus position (R1). The un speeded secondary task consisted of reporting verbally whether the stimuli were the same or different (R2). Stimulus exposure time was either 150 or 2000 msec. Two groups of subjects performed the primary task only, whereas two other groups performed both tasks and were instructed to emit R1 before R2. It was reasoned that the decision would be made to emit R1 before R2, and that this decision would produce a lengthening of R1. The results supported this prediction. Experiment 2 showed that the interference effect also occurred when the subjects were not explicitly instructed to emit R1 before R2, and was not due to either the mere presence of the second task or to response grouping. Experiments 3 and 4 compared two possible models for explaining the interference effect, i.e. the capacity-sharing model and the postponement model. As predicted by the postponement model, task difficulty did not interact, or interacted underadditively, with task overlap (Experiment 3), and the interference effect was not influenced by the amount of processing resources devoted to the primary task (Experiment 4). It was concluded that this new type of interference effect is best explained by the version of the postponement model that locates the bottleneck at the decision stage.     

SCIENCE,RELIGION, AND THE MEANING OF LIFE AND THE UNIVERSE: “AMALGAM” NARRATIVES OF POLISH NATURAL SCIENTISTS

This article deals with phenomena occurring at the interface of the existential, the religious, and scientific inquiry. On the basis of in‐depth interviews with Polish physicists and biologists, I examine the role that science and religion play in their narrative of the meaning of the Universe and human life. I show that the narratives about meaning have a system‐related (“amalgam") character that is associated with responses to adjacent metaphysical questions, including those based on scientific knowledge. I reconstruct the typical amalgam questions of Polish scientists and come to a conclusion about the stability of religious and nonreligious amalgams in this group. Critically referring to the thesis concerning the secularizing impact of science, I conclude that science by itself does not have a destructive effect on Polish scientists’ confidence that life and the Universe are meaningful, but is rather an exacerbating factor of the existing worldview system.     

Distinguishing Caregiver Strain from Psychological Distress: Modeling the Relationships Among Child, Family, and Caregiver Variables

Although both have been used in studies of the impact of mental illness on the family, the constructs of caregiver strain (often referred to as burden of care) and psychological distress have not been clearly distinguished. The vagueness surrounding these constructs, and the lack of a cohesive conceptual framework for understanding how they relate, leads to contradictory interpretations of results. This compromises the building of the knowledge base needed to develop and evaluate interventions to support families as they struggle to meet the needs of their children with emotional and behavioral challenges. We utilized the ABCX Model as a framework for understanding caregiver strain and its relationship to psychological distress. Structural equations modeling was used to test the hypothesized relationship between caregiver strain and psychological distress, as well as the role of key child and family variables. These included child symptoms, stressful life events, social support, family functioning, and material resources. Our findings indicated that caregiver strain and psychological distress, although related, have distinct correlates and different implications in the family context.     

Patterns of adaptation to conflict and schizoid personality scale scores

A previous investigation gave no evidence of a significant relationship of patterns of adaptation to conflict, as measured with the Serial Color-Word Test, with the Schizoid Personality Scale of the Coolidge Axis II Inventory. As a new scoring algorithm has subsequently been proposed for the latter scale, a replication was done with the modified schizoid scale. A group of 75 consecutive nonpsychotic women outpatients was given the Serial Color-Word Test and Coolidge's inventory. Both multiple and logistic regressions selected two significant predictors of schizoid personality, corresponding to high values of linear change in reading times during Trials 3 and 5 of the Serial Color-Word Test, i.e., to an increasingly rigid and inflexible style of the adaptive process. A multivariate analysis of variance yielded an effect size of .22 (partial eta2).     

Gender and family factors as predictors of late adolescent emotional expressiveness and adjustment: A longitudinal study

This study examined the longterm effects of the socialization of emotion in a sample of European American families. Late adolescents, whose families had been more emotionally expressive and accepting of emotions when they were in fifth grade, were more likely to report showing emotions not traditionally associated with their gender roles—specifically, males reported a greater propensity for crying, and females reported a greater tendency to express anger. In addition, in late adolescence, greater frequency of showing fear and showing warmth or affection were associated with higher levels of social and psychological adjustment—whereas crying was associated with better adjustment for males and poorer adjustment for females. Overall, adolescent females tended to report a higher level of emotional expressiveness and a higher level of family support of emotions than did adolescent males.

School characteristics among children of alcoholic parents

Studies show that children of alcoholics constitute a population at-risk commonly for poor performance, skipping school days, and school drop out. The focus of the present study was to examine a variety of direct outcome variables measuring academic performance among a sample of 226 children, 108 of them from parents who misused alcohol in Cadiz. Parents were outpatients of a Health Service and received treatment for the drinking problem; 118 students were children of nonalcoholic parents attending the same schools as the children of alcoholic parents. Both groups were compared on age, sex, school grade, and social environment. The study identified five variables on which performance by children of alcoholic parents was poorer: intelligence, repeating a grade, low academic performance, skipping school days, and dropping out of school.     

Timed picture naming in seven languages

Timed picture naming was compared in seven languages that vary along dimensions known to affect lexical access. Analyses over items focused on factors that determine cross-language universals and cross-language disparities. With regard to universals, number of alternative names had large effects on reaction time within and across languages after target-name agreement was controlled, suggesting inhibitory effects from lexical competitors. For all the languages, word frequency and goodness of depiction had large effects, but objective picture complexity did not. Effects of word structure variables (length, syllable structure, compounding, and initial frication) varied markedly over languages. Strong cross-language correlations were found in naming latencies, frequency, and length. Other-language frequency effects were observed (e.g., Chinese frequencies predicting Spanish reaction times) even after within-language effects were controlled (e.g., Spanish frequencies predicting Spanish reaction times). These surprising cross-language correlations challenge widely held assumptions about the lexical locus of length and frequency effects, suggesting instead that they may (at least in part) reflect familiarity and accessibility at a conceptual level that is shared over languages.     

Dialogue and Dominance in Couple Therapy for Depression: Exploring Therapists’ Responses in Creating Collaborative Moments

Previous investigations have found specific communication patterns in couples dealing with depression, specifically when depression concurs with conjugal conflicts. The presence of these patterns can reflect couples’ difficulties in engaging in collaborative communication during their sessions, posing a real challenge for therapists. This exploratory study uses a dialogical approach to examine issues of dominance and type of dialogue in two couples who differed in terms of their levels of dyadic adjustment. The therapists’ reactions were explored in order to detect the kinds of responses that were most effective at engendering a collaborative attitude in therapy sessions. The method used to analyze the dialogue was Dialogical Investigations of Happenings of Change (DIHC). Results on dominance indicated that the degree of quantitative and semantic dominance displayed by a different member of the couple in each case was illustrative of their relational dynamics, while in both cases interactional dominance was exercised by the therapists. Results on dialogue revealed that dialogic dialogue might help to coconstruct new shared meanings of depression. The findings indicated that certain responses by therapists as part of the dialogue could be useful in bringing about a reduction in hostility between the members of a couple, provided that the responses are maintained over the course of the session. Some research and clinical implications that emerge from the results are discussed.
