Psychological adaptation after marital disruption: the effects of optimism and perceived control

The present study explored the extent to which the two personality factors--perceived control and dispositional optimism--are related to psychological adaptation after marital disruption. A sample of 658 recently divorced individuals participated in the study by filling in an anonymous questionnaire. Bivariate findings revealed that perceived control and optimism were strongly related to psychological adaptation. However, when both predictors were included in a multiple regression analysis, optimism had a much larger effect than perceived control. The findings clearly indicate that personality factors account for a substantial proportion of the variance in adaptation to marital disruption.     

Adding a baby to the equation. married and cohabiting women's relationship satisfaction in the transition to parenthood

The trajectory of relationship satisfaction among married and cohabiting women in their transition to parenthood was compared in a potential sample of 71,504 women taking part in the Norwegian Mother and Child Cohort Study (MoBa). Prospective longitudinal data were collected in 4 waves over a 2-year period starting 6 months prebirth. Results from latent curve models suggested that married and cohabiting women experience similar negative change in relationship satisfaction during the transition to parenthood. However, cohabiting women start off and stay less satisfied throughout the transition period, suggesting the presence of a negative cohabitation effect that prevailed after controlling for various covariates. Extending investigation on the cohabitation effect to the transition to parenthood, and replicating it in a Scandinavian context, is discussed in relation to the understanding of what causes the cohabitation effect, and its clinical implications.     

Judgements vs affective evaluations of counterfactual outcomes

Counterfactual thoughts are imagined alternatives to past events and outcomes. Such thoughts may address possible consequences and effects of a counterfactual turn of events, and also an affective evaluation of that simulated outcome. Previous research has shown that estimates of counterfactual consequences are exaggerated (Teigen, Kanten, & Terum, 2011). The present research compared both consequence estimates and affective evaluations of factual and counterfactual outcomes. Consistent with previous findings, participants exaggerated consequence estimates, but affective evaluations indicated an opposite effect: Factual events were evaluated as more emotionally impressive than comparable counterfactual outcomes, for both negative (Experiment 1) and positive outcomes (Experiment 2). We discuss these apparently contradictory findings within the framework of construal level theory and suggest that both findings are compatible with an abstract, high-level account of counterfactual thinking.     

Reversed PREE under multiple schedules: Exploration of a modulation hypothesis

When reinforcer rates are manipulated in within-subjects designs, persistence in subsequent extinction trials is sometimes greater to the response alternative associated with the higher reinforcer rate (“reversed” partial reinforcement extinction effect, RPREE). The RPREE is often held to be a contradiction to the conventional PREE. To explore the interaction between these effects, student subjects were exposed to a multiple high-density and low-density reinforcement schedule, then to extinction conditions. Subjects in two control conditions received the high- and low-density schedules only. For all groups, general extinction persistence was elevated, and a within-subjects RPREE occurred under the multiple schedule. The RPREE was caused by the low-density component increasing persistence to the high-density component; the high-density component did not decrease persistence to the low-density component. These results support the view that the RPREE may be a within-subjects effect of the conventional PREE.     

Cellular memory in spinal nociceptive circuitry

Besides transmitting and processing, neurons may also store information for prolonged periods of time (e.g. by use-dependent change in synaptic strength). In 1966 long-term potentiation (LTP) of synaptic transmission was discovered in the hippocampus, an area implicated in learning and memory. Recent studies show that similar mechanisms apply to pain pathways, at least in the spinal cord, and may account for some forms of clinical problems like hyperalgesia, allodynia, and deafferentation pain states, such as phantom pain. In this review, we briefly summarize key aspects of synaptic plasticity known from the brain and in the spinal cord. Then we describe and discuss related changes in spinal nociceptive neurons based on results from our own laboratory.     

Extinction after partial reinforcement: predicted vs. judged persistence

The partial reinforcement extinction effect (PREE) (i.e., increased persistence following partial reward) is one of the most important generalizations from experimental studies of learning. Many theories of PREE assume that it involves cognitive and emotional mechanisms, but investigations of PREE have focused almost exclusively on behavioral measures. Four experiments with human adults investigated whether PREE is also reflected in cognitive measures. Independent groups of subjects learned an instrumental response under CRF vs. PRF contingencies, and then predicted (Experiments 1, 2, and 3) and/or judged (Experiments 3 and 4) their own persistence under extinction conditions. Predictions of persistcnce were unrelated to prior continuous or partial reinforcement contingencies (Experiments 1, 2, and 3), but subsequent judgments of persistence behavior were accurate (Experiments 3 and 4). These results indicate that increased persistence due to occasional reward is not well represented cognitively prior to its behavioral manifestation, but it is well represented after that manifestation. Possible explanations and implications of this apparent behavior cognition dissociation are discussed.     

THE RANDOMIZED BLOCKS DESIGN: A procedure for checking the success of the forming of blocks

S trømnes , F. J. The randomized blocks design. A procedure for checking the success of the forming of blocks. Scand. J. Psychol ., 1968, 9, 17–18.—A simple check for the success of any particular attempt at making a randomized blocks design is presented. It is proved that evaluation can be performed by comparing the mean square for blocks with the mean square for the residual. If the residual mean square is the greater one , the randomized groups design might be used in analysis.     

THE STRAIGHT SERIAL CURVE IN ANTICIPATION

S trømnes F. J. The straight serial curve in anticipation. Evidence for a new invariance. Scand. J. Psychol ., 1972, 13 , 43–53.—The bow-shaped serial curve in anticipation learning is usually generated by using counterbalancing techniques. Numerous curves in the literature testify that serial curves from experiments without counterbalancing are often very irregular in appearance. Plotting such curves as well as the classical bow-shaped ones by proportions of errors and omissions as a function of order of learning, the curves can be shown to be straight ascending ones. On the average subjects thus learn a series of verbal items at a constant rate, irrespective of the experimenter-determined order of the items.     

Death anxiety and visual oculomotor processing of arousing stimuli in a free view setting

The main goal of this study was to determine how death anxiety (DA) affects visual processing when confronted with arousing stimuli. A total of 26 males and females were primed with either DA or a neutral primer and were given a free view/free choice task where eye movement was measured using an eye tracker. The goal was to identify measurable/observable indicators of whether the subjects were under the influence of DA during the free view. We conducted an eye tracking study because this is an area where we believe it is possible to find observable indicators. Ultimately, we observed some changes in the visual behavior, such as a prolonged average latency, altered sensitivity to the repetition of stimuli, longer fixations, less time in saccadic activity, and fewer classifications related to focal and ambient processing, which appear to occur under the influence of DA when the subjects are confronted with arousing stimuli.     

DEVELOPMENT AND DIFFERENTIATION OF ACQUAINTANCE IN ENGAGED AND MARRIED COUPLES

Five married and 5 engaged couples, matched on socio-economic and interactional criteria, completed the Allport-Vernon-Lindzey Study of Values and Gordon's personality tests and predicted their mate's answers on these tests. Married partners predicted significantly better than engaged partners on the Study of Values but not on the Gordon tests. With the second part of the Study of Values, engaged couples predicted the mate's preferred motives relatively better than non-preferred ones, whereas married partners were equally well acquainted with both types. The results are discussed in terms of pain-avoidance by cognitive means in open versus closed ecological fields.
