Children's Adjustment in a Climate of Political Violence: Comparing Mother and Child Reports

There is a dearth of research on parent and child reports regarding a parent’s parenting and its contribution to a child’s adjustment. Therefore, the current study examined: (a) the differences between mother and child reports of aspects of maternal parenting (i.e., care and control), among both boys and girls; (b) which parenting report (i.e., mother’s or child’s) makes a stronger contribution to mother and child reports of the child’s adjustment in the context of political violence. One hundred and twenty-one mother-child dyads (children aged seven to 12 years old (M?=?10.02, SD?=?1.03)), who were exposed to prolonged political violence, participated in this study. Maternal care and control were assessed by mother and child reports on the Parental Bonding Instrument. Child’s adjustment was assessed both by mother’s report of child’s total difficulties and child’s self-report of posttraumatic stress symptoms (PTSS). Results revealed that both the mothers of girls and the girls themselves reported higher care, in comparison to mothers of boys and the boys themselves, while mothers of boys and the boys themselves reported higher control. Higher maternal control, as reported by the child, was associated with the child’s self-reported PTSS. Higher maternal control, as reported by the mother, was associated with the child’s total difficulties, as reported by the mother. However, maternal care, whether reported by mother or child, was not found to be associated with the child’s adjustment. School-aged children and their mothers were in agreement regarding maternal dimensions and their contribution to children’s adjustment.     

Dispositional Attachment Orientations,Contextual Variations in Attachment Security,and Compassion Fatigue Among Volunteers Working With Traumatized Individuals

In the present article, we report a series of studies examining the links between attachment orientations and compassion fatigue among volunteers working with traumatized individuals. Participants were volunteers in several trauma‐related organizations, ranging in age from 18 to 69 years. In Study 1 (N = 148), we examined associations between self‐reports of attachment insecurities and compassion fatigue. In Study 2 (N = 54), we used a diary design to assess attachment‐related differences in emotional reactions to actual helping encounters over a 2‐month period. In Study 3 (N = 108), we examined the effects of the experimental enhancement of attachment security (security priming) on reactions to a hypothetical helping encounter. As expected, attachment insecurities, either anxiety or avoidance, were associated with heightened compassion fatigue. Moreover, security priming reduced compassion fatigue in response to a hypothetical helping encounter. These findings underscore the relevance of attachment theory for understanding and preventing compassion fatigue.     

Universality,Particularity, and Potentiality: The Sources of Human Divergence as Arise from Wilhelm Dilthey’s Writings

This study examines the sources of human divergence as arise from Wilhelm Dilthey’s writings. While Dilthey assigns a central role to the human subject, he never synthesizes his major ideas on subjectivity into a unified theory of subjective uniqueness. I will show that such a theory can be derived from his writings through the combination of three ideas that appear in them. These ideas are: (1) the thesis that human understanding is possible because of psychological content that is shared by both the creator and the interpreter; (2) the belief that this shared content is the only content that exists within human beings, meaning that there is no unique psychological content; and (3) the perception of this inner universal content as an accumulation of life-possibilities. When joined together, these ideas create an inspiring theory of human divergence, according to which the uniqueness of an individual is determined through partial realization of universal possibilities.     

The effect of a reason's truth-value on the judgment of a fallacious argument

Informal reasoning fallacies are arguments that are psychologically persuasive but not valid. In the context of informal reasoning fallacies, the truth-value of the reason in support of a given claim is irrelevant to judging the validity of the argument as a whole. This property stands in sharp contrast with the general role of the reason's truth-value in judging arguments in general. The aim of this study was to test the hypothesis that in the context of informal reasoning fallacies the truth-value of a reason influences pupils' judgment of the extent to which the reason supports the claim. The results of the study confirm the research hypothesis.     

Simultaneous vs. sequential requests in resource dilemmas with incomplete information

We consider a class of resource dilemmas of the following form: members of groups of size n are asked to share a common resource pool whose exact size, x, is not known. Rather, x is sampled randomly from a probability distribution which is common knowledge. Each group member j (j = 1,…,n) requests r_j from the resource pool. Requests are made either simultaneously or sequentially. If (r₁+r₂+…+r_n) x all members are granted their requests; otherwise, group members get nothing.

For each protocol of play we present two alternative models - a game theoretical equilibrium solution and a psychological model incorporating the notion of focal points. We then report the results of two experiments designed to compare the two models under the two protocols of play.     

Effects of wealth on portfolios under various investment conditions

The present study addresses two major issues of portfolio selection tasks with one risky and one riskless alternative: (i) the effect of changes in capital on the proportion of capital put in savings, and (ii) the effect of the investment conditions (favorable vs unfavorable) on saving behavior. These two issues were investigated experimentally in a computer-controlled, discrete-time, multistage betting game in which each of 28 subjects had to make about 400 betting and savings decisions. The two major findings are: (i) the proportion of capital saved increases with the amount of capital on hand, and (ii) the proportion of capital saved decreases with practice when the investment conditions are favorable and increases with practice when they are unfavorable.     

How one gambles if one must: Effects of differing return rates on multistage betting decisions

In the multistage betting game (MBG), a decision maker (DM) is provided with some capital x which he is required to bet over m (m > 1) mutually exclusive and collectively exhaustive alternatives, each of which occurs with probability p_i (p_i > 0, i = 1,…, m; Σ_{i = 1}^mp_i = 1). If y_i is bet on alternative i (y_i ≥ 0, Σ_{i = 1}^my_i = x) and alternative i obtains, the DM's capital for the next stage is y_ir_i, (r_i > 0). The MBG lasts until either the DM loses his capital or N stages elapse, whichever comes first. Each of six subjects participated in six sessions consisting of several hundred 3-alternative MBG stages. A within-subject design assigned negative expected value (EV) bets to the first three sessions and positive EV bets to three more sessions. Significant effects were found due to return rate, capital size, homogeneous runs of either wins or losses, and individual differences. Four maximization of expected utility and two minimization of risk models were presented and tested. A modified logarithmic utility model is proposed, which provides the best fit to the data. The implications of the results and directions for further research are briefly discussed.     

Experimental tests of the mean-variance model for portfolio selection

Statistically knowledgeable male and female undergraduate students participated in 40 portfolio selection problems with monetary payoff contingent on performance. The portfolio selection task included two independent risky assets with normally distributed returns. It provided access to information about previous returns, allowed borrowing and lending at a fixed interest rate, and forced on each decision period a choice between the two risky assets. The findings show a high percentage of inefficient mean-variance portfolios which does not decrease with practice, a high rate of requests for useless information, a large frequency of switches between the two risky assets, and sequential dependencies. Theoretical and practical implications of the findings are briefly discussed.
