Children's metamemorial judgments in an event recall task

Two studies were conducted in which two different indicators of metacognitive monitoring were investigated in a complex everyday memory task. In the first phase of each experiment, 8- and 10-year-olds as well as adults were shown a short event (video) and gave judgments of learning, that is, rated their certainty that they would later be able to recall specific details correctly. In the second phase of the experiments, participants underwent a memory interview about the event and in Study 2 also gave confidence judgments, that is, rated their certainty that the provided answers to the memory questions were correct. Results revealed significant influences of memory characteristics on monitoring in that delaying judgments and monitoring judgments concerning irretrievable information affected judgments of learning. From 8 years of age onward, there were relatively appropriate metamemorial monitoring abilities in both indicators. Moderate intraindividual consistency was found across the two measures of metacognitive monitoring, with a tendency toward higher consistency in older age groups. The results are discussed in terms of the adequacy of the underlying theoretical construct.     

Trajectories of maternal depressive symptoms, maternal sensitivity, and children's functioning at school entry

Using data from the National Institute of Child Health and Human Development Study of Early Child Care and Youth Development, the authors modeled trajectories of maternal depressive symptoms from infant age 1 month to 7 years. The authors identified 6 trajectories of maternal depressive symptoms: high-chronic, moderate-increasing, high-decreasing, intermittent, moderate-stable, and low-stable. Women on these depression trajectories varied in sociodemographic risk and in changes in observed maternal sensitivity over time. Maternal sensitivity was generally higher and increased when depressive symptoms were low; sensitivity was lower and decreased when depressive symptoms were either high or increasing. Child outcomes at 1st grade were examined by trajectory group. The authors discuss the complexity of disentangling maternal symptoms from maternal sensitivity and sociodemographic risk when predicting children's functioning.     

Validation of the SASB Introject Surface in a Norwegian clinical and nonclinical sample

In this study, we examined the reliability and construct validity of the Structural Analysis of Social Behavior Introject Surface, Intrex long form A (SASB-IS; Benjamin, 1995) in 2 Norwegian samples. The fit of the 8 SASB-IS scales to the structural requirements of a circumplex model with relaxed equal spacing constraints was reasonably good in an outpatient sample, but poor in a normal reference sample. The deviations from the equal spacing based on an ideal circumplex model, however, seem to have minimal implications for the utility of the instrument in clinical assessment. The reliability of the SASB-IS was acceptable on most scales, but two scales had unacceptable low reliability. Correspondence with external criteria supported the validity of the SASB-IS in both samples. Profile patterns related to different segments of the introject circumplex model were systematically related to severity of psychopathology: Hostile and accepting patterns of self-relatedness formed polar opposites; control patterns and intermediate patterns gave intermediate pathology scores.     

Top-down inhibition of search distractors in parallel visual search

In three experiments, we examined distractor inhibition in parallel ("pop-out") visual search. Distractor inhibition was measured in terms of reaction time (RT) to a simple luminance increment probe presented, after the search task response, at display locations that either contained a search distractor (on-probe) or were blank (off-probe). When the search stimuli remained in view, the on-probe (relative to off-probe) RT cost was larger than in a baseline condition in which observers had only to passively view, rather than search, the display. This differential on-probe RT cost, which discounts effects of masking, was interpreted as a measure of distractor inhibition associated with target selection in parallel visual search. Taken together, the results argue that the distractor inhibition is an object-based and local phenomenon that affects all distractors (of a particular type) in an equal manner.     

Experimental comparison of dyspnea and pain

Dyspnea and pain are similarly unpleasant, alarming physical sensations, but studies examining both sensations in combination are lacking. In the present study, dyspnea was induced in 7 healthy volunteers by breathing through inspiratory resistive loads and the effects were compared with those of a heat pain stimulus. End-tidal partial pressures of carbon dioxide (PET_CO2), inspiratory time (Ti), breathing frequency (f), experienced unpleasantness, and intensity were measured. No difference was observed between dyspnea and pain in experienced intensity and unpleasantness (p >.05). During dyspneic stimulation, slightly higherTi was found than for pain (p<.08). PET_CO2 showed slight increases during the dyspneic versus the baseline and painful conditions (ΔPET_CO2=1.5 and 1.3 mmHg, respectively;p<.01 andp<.05). This study shows that the effects of dyspnea and heat pain can be compared within one experiment; both stimuli can be presented with similar intensity and unpleasantness, which is a prerequisite for comparing responses to them. The changes in PET_CO2 between our conditions were minimal, allowing an application of the present design to future fMRI studies.     

The time course of attentional and oculomotor capture reveals a common cause

Eye movements are often misdirected toward a distractor when it appears abruptly, an effect known as oculomotor capture. Fundamental differences between eye movements and attention have led to questions about the relationship of oculomotor capture to the more general effect of sudden onsets on performance, known as attentional capture. This study explores that issue by examining the time course of eye movements and manual localization responses to targets in the presence of sudden-onset distractors. The results demonstrate that for both response types, the proportion of trials on which responses are erroneously directed to sudden onsets reflects the quality of information about the visual display at a given point in time. Oculomotor capture appears to be a specific instance of a more general attentional capture effect. Differences and similarities between the two types of capture can be explained by the critical idea that the quality of information about a visual display changes over time and that different response systems tend to access this information at different moments in time.     

Measuring Big-Five personality dimensions with the implicit association test – Implicit personality traits or self-esteem?

We examined whether the implicit association test (IAT) could serve as an implicit measure of the dimensions of the Five-Factor Model of Personality. In the first study (N = 84) IAT-effects of the Big-Five (Extraversion, Agreeableness, Conscientiousness, Neuroticism and Openness) were found and the IAT showed good internal consistencies and convergent validity with an explicit Big-Five questionnaire (NEO-FFI-30). In a second study (N = 50), conducted to determine the overlap of the personality-IATs with implicit self-esteem, the Extraversion and the Neuroticism-IAT were shown to correlate with a self-esteem-IAT only moderately.     

The Social Networks of Women Experiencing Domestic Violence

The research literature has demonstrated that battered women living in shelters experience impaired social support. This study examines this phenomenon among battered women living in the community. This study compared a group of pregnant battered women (n = 145) and a group of pregnant nonbattered women (n = 58) in terms of their structural [e.g., total number of supporters, network members in violent relationships with their partners (an index of homophily or nonhomophily) and functional (e.g., emotional)] social support. Four reasons for impaired support in battered women were proposed and examined, including social isolation, failure to disclose abuse, homophily, and low SES. Only homophily was related to impaired support among battered women. In addition, the relationship between structural and functional support and mental health outcomes (e.g., depression, self-esteem) was examined. Criticism, practical support, homophily, and disclosure were all significant predictors of mental health for battered women. Implications for community-based interventions are discussed in the context of current intervention strategies with battered women.
