Rat defensive behavior: burying noxious food.

In Experiment 1, rats living in chambers containing bedding material were injected with a toxicosis-producing dose of lithium chloride shortly after their initial taste of sweetened condensed milk. They consumed no additional milk and used the bedding to bury the spout through which the milk had been delivered, although they did not bury a concurrently available water spout. In another control condition, rats did not bury a spout containing a novel solution (saccharin) not paired with toxicosis. In Experiment 2, rats did not bury a milk spout until milk consumption was followed by toxicosis. In Experiment 3, rats buried a spout containing Tabasco pepper sauce but not a concurrently available water spout. Thus, burying the food source appears to be an integral component of the rat's defensive reaction to noxious food.     

Short‐term psychodynamic infant–parent interventions at Child health centers: Outcomes on parental depression and infant social–emotional functioning

Randomized controlled trials (RCTs) demonstrate efficacy of parent–infant psychotherapy, but its applicability and effectiveness in public health care are less known. The method followed is Naturalistic study evaluating Short‐term Psychodynamic Infant–Parent Interventions at Child Health Centers (SPIPIC) in Stockholm, Sweden. One hundred distressed mothers with infants were recruited by supervised nurses. Six therapists provided 4.3 therapy sessions on average (SD = 3.3). Sessions typically included the mothers, often with the baby present, while fathers rarely attended sessions. The Edinburgh Postnatal Depression Scale (EPDS) and the Ages and Stages Questionnaire: Social–Emotional (ASQ: SE) were distributed at baseline and at 3 and 9 months later. Data from a nonclinical group were collected simultaneously to provide norm data. Multilevel growth models on the mothers’ questionnaire scores showed significant decreases over time on both measures. Nine months after baseline, 50% achieved a reliable change on the EPDS and 14% on the ASQ: SE. Prepost effect‐sizes (d) were 0.70 and 0.40 for EPDS and ASQ: SE, figures that are comparable to results of other controlled studies. Psychotherapists integrated with public health care seem to achieve good results when supporting distressed mothers with brief interventions in the postnatal period. SPIPIC needs to be compared with other modalities and organizational frameworks.     

SOME CORRELATIONS BETWEEN METHODS OF KNOWING AND THEOLOGICAL CONCEPTS IN ARTHUR PEACOCKE'S PERSONALISTIC PANENTHEISM AND NONPERSONAL NATURALISTIC THEISM

Differences in methods of knowing correlate with differences in concepts about what is known. This is an underlying issue in science and religion. It is seen, first, in Arthur Peacocke's reasoning about God as transcendent and personal, is based on an assumption of correlative thinking that like causes like. This contrasts with a notion of causation in empirical science, which explains the emergence of new phenomena as originating from temporally prior phenomena quite unlike that which emerges. The scientific understanding of causation is compatible with a naturalistic theism that holds a nonpersonal model of God as the creative process. However, focusing on the immanence of God, there is a second correlation between methods of knowing and concepts of God. Classical empiricism, used by science, correlates with God understood nonpersonally as the creative process. Radical empiricism, in which feelings and not only sense perceptions have cognitive import, opens up the possibility that one can experience Peacocke's personal, panentheistic God as pattern‐forming influence. I illustrate this second method‐concept correlation with a personal experience.     

Bringing It All Back Home: How Outside Stressors Shape Families' Everyday Lives

ABSTRACT— Families are dynamic systems that are permeable to influences from the outside world, such as daily stressors at work and at school. Our research uses naturalistic methods to investigate how family interactions change in response to such experiences and how other family members contribute to that process. We argue that the short-term effects of daily stressors on family dynamics can have cumulative, long-term implications for family health and functioning. Naturalistic studies that incorporate daily diary, observational, and physiological measures can offer new insights into families' everyday stress responding and coping processes.     

The New Person-Specific Paradigm in Psychology

ABSTRACT— Most research methodology in the behavioral sciences employs interindividual analyses, which provide information about the state of affairs of the population. However, as shown by classical mathematical-statistical theorems (the ergodic theorems), such analyses do not provide information for, and cannot be applied at, the level of the individual, except on rare occasions when the processes of interest meet certain stringent conditions. When psychological processes violate these conditions, the interindividual analyses that are now standardly applied have to be replaced by analysis of intraindividual variation in order to obtain valid results. Two illustrations involving analysis of intraindividual variation of personality and emotional processes are given.     

知觉运动学习中的背景干扰效应和元认知监测

选取大学生为被试,采用两因素混合实验设计,以预期按键反应作为知觉运动学习任务.在运动学习任务中,设置了集中练习和分散练习两种练习方式以及三个练习一测试组块.通过分析不同练习方式和练习-测试组块对练习成绩、测试成绩以及元认知监测的影响,考察运动知觉学习的背景干扰效应、练习伴随低估效应以及元认知监测的依据.结果发现: (1)缩短练习与测试之间的时间间隔,经典的背景干扰效应没有出现; (2)在知觉运动学习的多组块练习过程中.元认知监测准确性没有出现练习伴随低估效应; (3)集中练习组更多地以当前的练习成绩作为依据进行预测,从而导致了对预测的高估.     

Relevance differently affects the truth,acceptability, and probability evaluations of “and”, “but”, “therefore”, and “if–then”

In this study, we investigate the influence of reason-relation readings of indicative conditionals and “and”/“but”/“therefore” sentences on various cognitive assessments. According to the Frege–Grice tradition, a dissociation is expected. Specifically, differences in the reason-relation reading of these sentences should affect participants’ evaluations of their acceptability but not of their truth value. In two experiments we tested this assumption by introducing a relevance manipulation into the truth-table task as well as in other tasks assessing the participants’ acceptability and probability evaluations. Across the two experiments, a strong dissociation was found. The reason-relation reading of all four sentences strongly affected their probability and acceptability evaluations, but hardly affected their respective truth evaluations. Implications of this result for recent work on indicative conditionals are discussed.     

Are economic conditions related to nonnormative life satisfaction development? Evaluating the relative impact of economic conditions,personality, and subjective health

This study examined the relative contribution of psychological and socioeconomic resources to explaining qualitative individual differences in life satisfaction development. We used growth mixture modeling and a cohort‐sequential design to investigate life satisfaction development from ages 25 to 65, in a nationally representative panel (the Socioeconomic Panel). Eighty‐three percent of the participants experienced stability in life satisfaction. In a subgroup of individuals (10%), life satisfaction declined. This subgroup lived under less favorable economic conditions and reported downward moves on an index of socioeconomic status. In another subgroup (7%), life satisfaction was low at age 25 and increased up to age 65. This group was also socioeconomically disadvantaged but scored higher on adaptive personality traits and experienced upward social mobility. Generally, personality traits explained level differences in life satisfaction better than economic conditions. However, economic conditions explained nonnormative life satisfaction development better than generalized control beliefs and the Big Five traits.     

Living Conditions and Psychological Distress in Latino Migrant Day Laborers: The Role of Cultural and Community Protective Factors

The purpose of this study was to examine the relationship between typically difficult living conditions and psychological distress in Latino migrant day laborers (LMDLs), with attention to the potentially protective roles of contact with family in country of origin (i.e., communication, sending money, etc.), availability of local culture (i.e., food, music, people from one's country of origin), and utilization of community resources perceived to be culturally competent (i.e., services that are respectful, able to serve Latinos, able to solve problems, in Spanish, etc.). Participants were 344 LMDLs surveyed in the San Francisco Bay Area. As hypothesized: (a) difficult living conditions were related to depression, anxiety, and desesperación [desperation], the latter a popular Latino idiom of psychological distress recently validated on LMDLs; (b) contact with family moderated the relation between difficult living conditions and depression and desesperación but not anxiety and (c) access to local culture, and utilization of community resources, mediated the relation between difficult living conditions and depression and desesperación but not anxiety. Implications for intervening at local and larger levels in order to provide some protection against distress built into the LMDL experience in the United States are discussed.
