Conflict resolution in women is related to trait aggression and menstrual cycle phase

Twenty‐four women with a diagnosis of premenstrual dysphoric disorder (PMDD) and 18 controls took part in a study of patterns of female aggression. They completed a version of the Conflict Tactics Scale for a premenstrual and a follicular phase of their menstrual cycle and for the past year. The Life History of Aggression was completed during a clinician interview. The women used more aggressive tactics to solve conflicts in the premenstrual than in the follicular phase, but the difference was only significant for the PMDD group. During the past year, reasoning was the most common strategy used by women to resolve conflicts, but verbal aggression was also prevalent. Although physical violence was less common, the prevalence of any act of violence was 33% in the controls and 62% in the clinical group. Women with PMDD used both verbal and physical aggression more frequently than the controls and had a higher lifetime history of aggression. Aggression by women toward partners was associated with a general tendency to act aggressively. Aggr. Behav. 29:228–238, 2003. © 2003 Wiley‐Liss, Inc.     

Exploring the time prediction process: the effects of task experience and complexity on prediction accuracy

Whilst considerable research shows that people tend to underestimate their task completion times, there is little research concerning factors that mediate the time prediction process. In Experiments 1 to 3 a simple, well‐structured task, the 3‐disk Tower of Hanoi, showed no evidence of underestimation; in fact, participants consistently overestimated the duration of this task. However, predictions were more accurate among participants who acquired some task experience beforehand. Task complexity was also found to be an important factor since the more cognitively complex 4‐ and 5‐disk versions produced less biased predictions. Using a cognitively undemanding disk movement task, we found a general temporal overestimation in Experiment 4, thus suggesting that task duration might be responsible for the general lack of underestimation in the present studies. These results have implications for the planning of tasks in everyday life, and also suggest conditions under which time prediction accuracy can be improved.

Preliminary psychometric properties of the Acceptance and Action Questionnaire-II: a revised measure of psychological inflexibility and experiential avoidance

The present research describes the development and psychometric evaluation of a second version of the Acceptance and Action Questionnaire (AAQ-II), which assesses the construct referred to as, variously, acceptance, experiential avoidance, and psychological inflexibility. Results from 2,816 participants across six samples indicate the satisfactory structure, reliability, and validity of this measure. For example, the mean alpha coefficient is .84 (.78–.88), and the 3- and 12-month test–retest reliability is .81 and .79, respectively. Results indicate that AAQ-II scores concurrently, longitudinally, and incrementally predict a range of outcomes, from mental health to work absence rates, that are consistent with its underlying theory. The AAQ-II also demonstrates appropriate discriminant validity. The AAQ-II appears to measure the same concept as the AAQ-I (r = .97) but with better psychometric consistency.     

A place within the heart: finding a home with parental objects

For adopted and Looked After children with compromised early experiences, there can be troubling phantasies and anxieties associated with parental objects. These internal object relations can seriously restrict the development of secure intimate relationships with new parental figures. Adoptive parents and foster carers bear the brunt of the associated difficulties. Clinical work with the child, parents/carers, family, or network, may help processes of containment, differentiation, working through, mourning, and integration. This paper is based on thinking derived from clinical work with children who are adopted or Looked After, and with adoptive parental couples, carers, and networks. The primary focus is on how the child needs to find a ‘psychic home’ in the minds of others for their damaged internal parental objects, and the emotional capacities required in adoptive parents to provide this. I describe some of the complexities for adoptive parents and others in providing what is needed to enable the child to experience their internal parental objects in a fuller way. This process can allow the child to introject, identify with, and re-imagine their internal parental objects, and through this develop a more realistic relationship to their adoptive parents and to their birth parents. It promotes trust, freedom, and emotional depth in the relationship with parental figures.     

Opportunities for Immigrants’ Acculturation and Identification Varieties

This article elucidates how members of the two largest immigration groups living in Germany (i.e., immigrants with a Russian or Turkish background) deal with and integrate values and practices deriving from their ethnocultural minority group and the larger society. A special emphasis of this article is on how context conditions form opportunities for varieties of acculturation and identification. The pattern of results suggests a taxonomy of immigrants’ acculturation, consisting of Blended Integration, Alternating Integration, Separation, and Dis‐Integration. This taxonomy is based on immigrants’ integration of cultural aspects, while it proved to be analytically useful to conceptualize their national self‐allocation as an additional dimension. Immigrants’ development of these different varieties was found to be linked to their perceptions of compatibility and acceptance by the larger society. Relative to immigrants with a Turkish background, immigrants with a Russian background experience less deep incompatibilities between values and practices deriving from the cultural groups, thus having more latitude for acculturation and integration. In contrast, immigrants with a Turkish background experience more challenges to acculturation and integration as a result of being confronted more frequently with incompatibilities and experience less societal acceptance. Further conceptual and societal implications are discussed.     

Individual Differences in Decision Making Depend on Cognitive Abilities,Monitoring and Control

Decision making is the process by which actions are constructed and initiated. Across many research streams, this can be explained in terms of three broad cognitive processes: cognitive abilities that construct judgements and potential courses of action, and interacting monitoring and control processes that determine when to initiate them as behaviour. The aim of this research was to investigate the generality of individual differences in these processes, and their power to predict patterns of decision behaviour identified in our previous research. Undergraduate participants (N = 364) completed nine tests assessing cognitive abilities, monitoring confidence, control thresholds and various patterns of decision behaviour. The tests differed in their cognitive ability requirements and the nature of the payoffs associated with decisions. Cognitive abilities were a strong predictor of individuals' decision competence and optimality, while monitoring confidence and control thresholds were strong and unique predictors of their overall decisiveness, and reckless and hesitant errors. These results were strongest when the measures of cognitive abilities and monitoring confidence were derived from tests with the same cognitive requirements as the tests used to derive the decision behaviours and when the control threshold measure was derived from tests with the same decision payoffs as the test used to derive the decision behaviours. This effect was particularly pronounced for control thresholds, highlighting the domain‐specific nature of cognitive control processes. These findings demonstrate how cognitive abilities, monitoring output and control thresholds interact with cognitive requirements and context‐specific payoffs to drive individual differences in decision‐making behaviour.

Iron in solution with aluminum matrix after non-equilibrium processing: an atom probe tomography study

In this paper, we report on the influence of rapid solidification and severe plastic deformation on the solid solubility of Fe in Al. Atom probe tomography, for the first time, was performed on fine (3–4 μm diameter) and coarse (~100 μm) as-atomised Al-5 at.% Fe powder and cryomilled Al-5 at.% Fe powder. The atomised powders exhibited negligible Fe in solution with Al, whereas the cryomilled powder contained ~2 at.% Fe in solution. Moreover, our results suggest that severe plastic deformation is preferable to atomisation/rapid solidification for increasing the non-equilibrium solid solubility of Fe in Al.
