THE IMPACT OF DEPRESSION ON MATERNAL RESPONSES TO INFANT FACES IN PREGNANCY

Research has suggested that prenatal depression may be associated with disrupted maternal responses to infant stimuli, with depressed pregnant women not showing the bias toward distressed infants as that observed in nondepressed pregnant women. The current study examined the effects of depression on self‐ reported responses to infant stimuli, in early pregnancy. Women with clinical depression (n = 38), and nondepressed women (n = 67) were recruited from a wider cognitive behavioral therapy trial. They completed Maternal Response Scales in which they were presented with images of distressed, neutral, and happy infant faces, with no time limit. The women rated their responses to these images along three dimensions—wanting to comfort, wanting to turn away, and feelings of anxiety—using Likert scales via a computerized task. There was evidence that women with depression in pregnancy showed different responses than did women without depression. Women with depression were substantially more likely to be in the highest quartile for ratings of wanting to turn away, odds (OR) ratio = 4.15, 95% confidence intervals (CIs) = 1.63–10.5, p = .003, and also were substantially less likely to be in the highest quartile for wanting to comfort a distressed infant face, OR = 0.22, 95% CIs = 0.09–0.54, p < .001. Findings are consistent with there being both a heightened avoidant and a reduced comforting response toward distressed infants in depressed pregnant women, providing some support that depression disrupts maternal preparations at a conscious level.

Age-related differences in sequence learning: Findings from two visuo-motor sequence learning tasks

The Serial Reaction Time Task (SRTT) is thought to assess implicit learning, which seems to be preserved with age. However, the reaction time (RT) measures employed on implicit-like tasks might be too unreliable to detect individual differences. We investigated whether RT-based measures mask age effects by comparing the performance of 43 younger and 35 older adults on SRTT and an explicit-like Predictive Sequence Learning Task (PSLT). RT-based measures (difference scores and a ratio) were collected for both tasks, and accuracy was additionally measured for PSLT. We also measured fluid abilities. The RT-difference scores indicated preserved SRTT and PSLT performance with age and did not correlate with fluid abilities, while ratio RT and the accuracy-based measures indicated age-related decline and correlated with fluid abilities. Therefore, RT-difference scores might mask individual differences, which compromises the interpretation of previous studies using SRTT.     

Repression in chronic pain: An idea worth recovering

Repression, defined as a process by which threatening information is kept out of conscious awareness, has long been a topic in the chronic pain literature. Emerging in psychodynamic theories, chronic pain is thought to arise from repressed emotions that are converted into physical symptoms; this notion seems to account for much anecdotal evidence and has received empirical support from work with Minnesota Multiphasic Personality Inventory (Hathaway & McKinley, 1943) profiles—particularly the conversion-V. However, the construct validity of this profile among pain patients has been called into question. The emergence of the cognitive-behavioral model of chronic pain ignited a proliferation of research, but because it rejected psychodynamic pain theory, investigation of repression was largely suspended. This lapse leaves unexplained—almost unrecognized—findings that a plurality of chronic pain patients are characterized by constrained emotion, and that repressed, inhibited, and denied negative emotions or traumatic memories have a profound impact on chronic pain. To address these important phenomena and to reinvigorate research, three methods are proposed: (a) expand current empirical clustering procedures, which rely on the Multidimensional Pain Inventory (Kerns, Turk, Rudy, 1985) with measures of defensiveness to isolate patients who report high pain/disability and deny negative affect; (b) employ Weinberger and colleagues' 1979 1990 “repressive style” to examine the responses of repressor pain patients; (c) pursue Pennebaker and colleagues' 1986 1988 theory about disclosure of traumatic events to examine effects of inhibition and disinhibition on persistent pain. Although an integrated model may be premature, it is argued that repression should receive renewed appreciation; it was never really absent, just forgotten.     

An Application of Brief Experimental Analysis with Early Writing

Students’ poor performance on national assessments of writing suggests that educators need effective approaches to assess and intervene with writing problems. Brief experimental analysis (BEA) has supporting evidence for identifying interventions in reading, but little research has investigated BEA with writing. Early writing is an especially important period for students, and the current study sought to extend BEA research in early writing. Results showed that BEAs for 3 first grade students identified promising writing interventions, and extended analyses showed improved performance for each student following implementation of the interventions. Implications for future research in direct assessment and intervention are discussed.     

Meta-Analysis of Single-Case Design Research: Introduction to the Special Issue

Single-case design (SCD) research focuses on finding powerful effects, but the influence of this methodology on the evidence-based practice (EBP) movement is questionable. Meta-analytic procedures may help facilitate the role of SCD research in the EBP movement, but meta-analyses of SCDs are controversial. The current article provides an introduction to the special issue on meta-analyses of SCD research by discussing concerns regarding the internal and external validity of these designs. Specific considerations for increasing the validity of SCD meta-analyses are provided, as are brief overviews of the articles included in the special issue.     

Risk dishabituation: in repeated gambling, risk is reduced following low-probability "surprising" events (wins or losses)

In path-dependent risk taking, like playing a slot machine, the wager on one trial may be affected by the outcome of the preceding trial. Previous studies have shown that a person's risk-taking preferences may change as a result of the preceding trial (win or loss). For example, the "house money effect" suggests that risk taking may increase after a win, whereas the "break even effect" posits that risk taking increases after a loss. Independent of those findings, a person's emotional state has been found to influence risk taking. For example, the "mood maintenance hypothesis" supports the notion that positive affect decreases risk taking, and related research finds that increased negative affect increases risk taking. Because winning and losing may influence one's emotional state, we sought to investigate how both previous outcomes, as well as a person's emotional responses to those outcomes, independently influence subsequent risk taking. To do this, data were collected using three simplified slot machines where the chance of winning each trial was set to 13%, 50%, and 87%, respectively. Evidence for the break even and house money effects were found on the 13% and 87% games, respectively. Likewise, emotional valence was found to predict risk taking on these two tasks, with emotional valence fully explaining the break even effect observed on the 13% game. In addition to these results, the present research revealed that risk taking is reduced following low-probability ("surprising") events (i.e., a win in the 13% condition or loss in the 87% condition). Dubbed "risk dishabituation," this phenomenon is discussed, along with its likely corresponding emotional experience--surprise.     

A Comparison of Children with Epilepsy to an Age- and IQ-Matched Control Group on the Children's Memory Scale

Past research has found that children with epilepsy exhibit decreased memory skills. In addition, some studies have found that children with epilepsy obtain significantly lower IQ scores than controls. In an effort to examine whether children with epilepsy have specific memory weaknesses versus global cognitive difficulties, the present study compared the performance of 62 children (age range = 6–16 years). Thirty-one children with epilepsy were compared to 31 age- and IQ-matched controls on the Children's Memory Scale (CMS) to determine whether differences in memory skills persist when IQ is matched. An independent t-test comparing index and scaled scores was performed. The results indicated that with the exception of the Word Pairs subtest (p < .01), children with epilepsy did not differ significantly on the CMS subtests when IQ was matched. This suggests that list-learning paradigms may be particularly sensitive to memory impairments in children with epilepsy and/or that children with epilepsy have more global cognitive impairments.
