Adult Attachment Dimensions,World View Schemas,and the Psychological Health of Parents of Infants in a Neonatal Intensive Care Unit

This study reports the results of an exploration of the relationship of adult attachment dimensions (closeness, dependence, and anxiety) and world view assumptions (benevolence, meaningfulness, and worthiness) to psychological distress and psychological well-being in 142 parents (71 couples) of newborns recently hospitalized in a neonatal intensive care unit. The results of the Actor-Partner Interdependence Model, hierarchical multiple regression, and mediation analyses showed that parents who were more comfortable with attachment-dependence and parents who held more positive beliefs about benevolence and worthiness had less psychological distress and more well-being. In addition, parents with partners who were more comfortable with attachment-dependence had less psychological distress and more well-being. Attachment-dependence partially mediated the relationships of benevolence and worthiness with psychological distress and the relationship of benevolence with psychological well-being, whereas worthiness had a direct relationship with psychological well-being.

为探讨社会排斥和社会接纳情境下儿童奖惩分配公平性,研究采用个体-偶然排斥范式和第三方奖惩分配范式,对8~9岁儿童奖惩分配公平性行为和奖惩分配公平性判断进行研究,结果发现：（1）社会排斥组被试的奖惩分配公平性行为显著多于社会接纳组,奖惩分配不公平性行为显著少于社会接纳组。9岁组被试的奖惩分配公平性行为显著多于8岁组,奖惩分配不公平性行为显著少于8岁组;（2）社会排斥组被试的奖惩分配公平性判断显著高于社会接纳组,9岁组被试的奖惩分配公平性判断显著高于8岁组,奖惩分配不公平性判断显著低于8岁组。结论：社会情境影响儿童的奖惩分配公平性,在排斥情境下,8~9岁儿童的奖惩分配公平性明显提升;8~9岁儿童的奖惩分配公平性随年龄增长有上升趋势。     

Fix and sample with rats in the dynamics of choice

The generality of the molar view of behavior was extended to the study of choice with rats, showing the usefulness of studying order at various levels of extendedness. Rats' presses on two levers produced food according to concurrent variable-interval variable-interval schedules. Seven different reinforcer ratios were arranged within each session, without cues identifying them, and separated by blackouts. To alternate between levers, rats pressed on a third changeover lever. Choice changed rapidly with changes in component reinforcer ratio, and more presses occurred on the lever with the higher reinforcer rate. With continuing reinforcers, choice shifted progressively in the direction of the reinforced lever, but shifted more slowly with each new reinforcer. Sensitivity to reinforcer ratio, as estimated by the generalized matching law, reached an average of 0.9 and exceeded that documented in previous studies with pigeons. Visits to the more-reinforced lever preceded by a reinforcer from that lever increased in duration, while all visits to the less-reinforced lever decreased in duration. Thus, the rats' performances moved faster toward fix and sample than did pigeons' performances in previous studies. Analysis of the effects of sequences of reinforcer sources indicated that sequences of five to seven reinforcers might have sufficed for studying local effects of reinforcers with rats. This study supports the idea that reinforcer sequences control choice between reinforcers, pulses in preference, and visits following reinforcers.     

A sub-process view of working memory capacity: Evidence from effects of speech on prose memory

In this article we outline a “sub-process view” of working memory capacity (WMC). This view suggests that any relationship between WMC and another construct (e.g., reading comprehension) is actually a relationship with a specific part of the WMC construct. The parts, called sub-processes, are functionally distinct and can be measured by intrusion errors in WMC tasks. Since the sub-processes are functionally distinct, some sub-process may be related to a certain phenomenon, whereas another sub-process is related to other phenomena. In two experiments we show that a sub-process (measured by immediate/current-list intrusions) is related to the effects of speech on prose memory (semantic auditory distraction), whereas another sub-process (measured by delayed/prior-list intrusions), known for its contribution to reading comprehension, is not. In Experiment 2 we developed a new WMC task called “size-comparison span” and found that the relationship between WMC and semantic auditory distraction is actually a relationship with a sub-process measured by current-list intrusions in our new task.     

No Justice Without Democracy: A Deliberative Approach to the Global Distribution of Wealth

Abstract

The debate about global distributive justice is characterized by an often stark opposition between universalistic approaches, advocating an egalitarian global redistribution of wealth (Beitz, Pogge, Barry, Tan), and particularistic positions, aiming to justify a restriction of redistribution to the domestic community (D. Miller, R. Miller, Blake, Nagel, Rawls). I argue that an approach starting from the deliberative model of democracy (Habermas) can overcome this opposition. On the one hand, the increasingly global scope of economic interactions implies that the range of individuals concerned with the redistribution of wealth should also be increasingly universal. On the other hand, the need for democratic deliberation refers to the fact that demands of justice should be contextual and should take into account the particular circumstances, needs and values of the people concerned. Both concerns can be realized simultaneously only within a multi‐layered democratic system in which redistribution is a concern at the domestic, the international and the global level.     

The Development of Attribute Dominance in the Knowledge Base

Two cuing, free-recall studies were conducted to test Bach and Underwood's (1970) hypothesis that acoustic encoding is dominant among second graders and semantic encoding is dominant among sixth graders. When retrieval cues were presented with to-be-remembered items at both input and output (Experiment 1), and when cues were presented only at output (Experiment 2), semantic cues were more efficient in elevating recall than were acoustic cues for both second and sixth graders. When these and other results generally found using recognition, sorting, incidental learning, and free-recall experimental designs are compared, it seems plausible that item presentation and memory-testing formats interact with age, and that these factors account for the different patterns of attribute dominance found in the literature. The knowledge base cannot be understood by focusing on either subject or task analyses, but only by focusing on interactions between subject and task variables as they change over time. The educational implications for young grade-school children are discussed.     

Still cautious: Personality characteristics of extremely low birth weight adults in their early 30s

Extremely low birth weight survivors (ELBW; <1000 g) display a personality style characterized by cautiousness, shyness, and risk aversion in their 20s. We examined whether non-impaired ELBW survivors were still more cautious than their normal birth weight (NBW) peers at ages 30–35 and assessed the stability of this personality characteristic across approximately a decade in the oldest known cohort of ELBW survivors. Of the 154 participants tested at ages 22–26, 111 (i.e., 72%) of them returned approximately 10 years later [i.e., 69% (49/71) ELBW and 75% (62/83) NBW], and once again they completed the Eysenck Personality Questionnaire-Revised (EPQ-R). We created the same theoretically and empirically derived composite measure of cautiousness at each visit by summing the EPQ-R psychoticism scale (reverse scored) and the EPQ-R lie scale. We found that ELBW adults reported higher cautiousness than their NBW counterparts at ages 30–35. We also found that levels of cautiousness remained stable over approximately 10 years in both groups. Our findings suggest that individuals born at ELBW were more cautious than NBW peers and that this personality characteristic remained stable into their early 30s. The present study appears to be the first empirical demonstration of personality stability among adult ELBW survivors.     

What Counts as Behavior? The Molar Multiscale View

Because the definition of behavior changes as our understanding of behavior changes, giving a final definition is impossible. One can, however, rule out some possibilities and propose some others based on what we currently know. Behavior is not simply movement, but must be defined by its function. Also, our understanding of behavior must agree with evolutionary theory. I suggest 4 basic principles: (a) only whole organisms behave; (b) behavior is purposive; (c) behavior takes time; and (d) behavior is choice. Saying that parts of an organism behave is nonsense, and, moreover, evolutionary theory explains the existence of organisms mainly through their adaptive behavior. Behavior is purposive in that behavior is shaped by its consequences, through an organism''s lifetime or through interactions with the environment across many generations of natural selection. Behavior takes time in that behavior is interaction with the environment that cannot take place at a moment. Moreover, at a moment in time, one cannot definitely identify the function of behavior. Identification of an activity requires a span of time. Behavior is choice in the sense that a suitable span of time always includes time spent in more than 1 activity. Activities include parts that are themselves activities on a smaller time scale and compete for time. Thus, behavior constitutes time allocation. An accounting problem arises whenever any behavior is attributed to multiple consequences. In the molar multiscale view, this raises the question of whether 2 activities can occur at the same time. The question remains open.
