Depressed mothers' newborns show longer habituation and fail to show face/voice preference

Twenty neonates of depressed and nondepressed mothers failed to show an initial visual preference for their mother's versus a female stranger's face/voice. Subsequently, infants were habituated to their mother's face and voice. Infants of depressed mothers required 1/3 more trials and almost twice as long to habituate. A posthabituation test with their mother and a different female stranger revealed a preference for the stranger's face for 9 out of the 10 newborns of the nondepressed mothers. Again, the infants of depressed mothers displayed no visual preference. These findings reveal differences in depressed mothers newborns' speed of habituation and face/voice preferences. ©2002 Michigan Association for Infant Mental Health.     

Lapses of intention and performance variability reveal age-related increases in fluctuations of executive control

We examine the hypothesis that the efficiency of executive control processes is less stable over time in older than younger adults. An age-related decrease in the efficiency of executive control should result in an increase in performance variability in task conditions requiring the recruitment of executive control processes and not in task conditions requiring minimal involvement of executive control. Performance variability was similar for younger and older adults in task conditions requiring minimal executive control and greater for older than younger adults in task conditions requiring executive control. These and other data are consistent with the proposal that aging is associated with a decrease in the stability of executive control over time.     

Smiling and relative status in news photographs

To test the hypothesis that lower social status is associated with more smiling, the authors used newspaper photographs and their associated news stories as the basis for scoring the smiling and relative social status of the 2 individuals in each photograph. Independent raters judged smiling and 5 dimensions of relative status for 496 individuals in 248 newspaper photographs. There was no relation between status and smiling, although status and smiling were both related to other variables such as gender, age, and story valence. These findings add to a growing body of evidence that there is no generalized relation between smiling and status.     

Relationship between the rorschach and the MMPI-2 in a Swedish population: a replication study of the effects of first-factor related test-interaction styles

A sizeable amount of research literature has failed to demonstrate a stable relationship between self-report and the Rorschach (Exner, 1993). However, principal component first-factor related test-interaction style has been shown to moderate convergence. In this study 78 psychiatric patients completed the Rorschach and the Minnesota Multiphasic Personality Inventory-2 (MMPI-2; Hathaway & McKinley, 1989). Practically no correlation was evident between the MMPI-2 and the Rorschach, measuring similar constructs, in all patients. Patients with similar test-interaction styles demonstrated positive intermethod correlations between both conceptually related and conceptually not directly related test indexes. The same scales were negatively correlated in patients with discordant test-interaction styles, and this difference between test-interaction style groups was significant. It is suggested that first-factor related test-interaction style moderates convergence. It is further suggested that test-interaction style moderates convergence between both conceptually related and conceptually not directly related measures of distress or psychopathology.     

Creativity, “Twinning,” and Self-Destruction in the Life and Work of Tennessee Williams

Applying an eclectic psychoanalytic framework, this paper provides a thematic link between the core experiences of Williams' early life and his creative work. Both preoedipal and Oedipal themes are elucidated. The central issue that dominated Williams' mental life was his struggle between a sense of suffocation and confinement, on the one hand, and having artistic and sexual freedom, on the other. The experience of suffocation extended to his dread of becoming mad. This dread derived from his intense twinning or twinship merger with his schizophrenic sister who was confined in an asylum. The study focuses attention on a number of Williams' one-act and full-length plays, written during each of the decades of his public career, as representative of his overall dramatic opus. These works are indicative of his special relationship with his sister as well as of his obsession about self-indulgence and fear of confinement. The later plays suggest that he was subject to identity confusion.     

Preferred Difficulty and Subjective Probability in Different Action Phases

Drawing on Gollwitzer's deliberative–implemental mindset distinction (P. M. Gollwitzer, 1990), it was predicted that people who are deliberating on different actions or goals would be more cautious or more realistic in their expectation of success in subsequent tasks than people who are going to implement a chosen action or goal. Participants were given a choice between different test-materials. They were interrupted before (deliberative) or immediately after decision-making (implemental). They then either had to choose between various levels of difficulty within one type of task (Experiment 1) or they had to predict their own future performance (Experiment 2). The results showed that deliberative participants preferred less difficult tasks and overestimated their probability of success less than implemental participants. In addition, deliberative participants referred more than implemental participants to their past performance when selecting levels of difficulty or predicting future performance; however, the two groups did not differ in actual performance. Taken together, the findings suggest that people are more realistic in a deliberative than in an implemental state of mind. The present studies extend prior research because for the first time they document mindset effects on peoples' estimates concerning their future performance in the achievement domain.     

Intended and unintended effects of explicit warnings on eyewitness suggestibility: Evidence from source identification tests

Previous studies have shown that source identification (ID) tests reduce, and in some cases eliminate, eyewitness suggestibility errors. The present study showed that the suggestibility errors participants committed on a source ID test were further reduced when they were given the explicit postwarning that the experimenter was trying to trick them. These postwarnings reduced suggestibility to the same extent as prewarnings, and they did so for both once and repeatedly suggested items. In addition, the benefits of the pre- and postwarnings persisted when participants were retested 1 week later, but only if the suggestions had been repeated. For once-suggested items, the warning had the unintended effect of improving old/new recognition of the suggested information at retest, an effect that offset the improvements in source discrimination accuracy conferred by the warning. The advantages of using source ID tests for investigating group differences in eyewitness suggestibility are discussed.     

The emotional attentional blink is robust to divided attention

The emotional attentional blink (EAB) refers to a temporary impairment in the ability to identify a target when it is preceded by an emotional distractor. It is thought to occur because the emotional salience of the distractor exogenously captures attention for a brief duration, rendering the target unattended and preventing it from reaching awareness. Here we tested the extent to which the EAB can be attenuated by inducing a diffuse top-down attentional state, which has been shown to improve target identification in an analogous attentional phenomenon, the attentional blink. Rapid sequences of landscape images were presented centrally, and participants reported the orientation of a ± 90° rotation of a landscape target. To induce a diffuse state of attention, participants were given a secondary task of monitoring for the appearance of a colored dot in the periphery. We found that emotional distractors impaired target recognition performance to comparable extents, regardless of whether or not participants concurrently performed the peripheral-monitoring task. Moreover, we found that performance of the secondary task led to an impaired ability to ignore neutral distractors. Subjective ratings of target vividness mirrored the behavioral accuracy, with frequent reports of intermediate levels of vividness suggesting that the EAB might impair target visibility in a graded manner. Our results demonstrate that the EAB is robust to manipulations of top-down attention, suggesting that the temporary capture of attention by emotionally salient stimuli involves processes that are distinct from those that produce the attentional blink.     

Compensatory biases after ingroup threat: ‘yeah,but we have a good personality’

It was hypothesized that participants who strongly identify with the ingroup and receive unfavorable feedback about their group in one domain would compensate on alternative dimensions. A group of emergency medical service volunteers received negative, positive or no feedback on their volunteer organization and were asked to rate the ingroup and an outgroup on dimensions alternative to the feedback. As predicted, high identifiers showed an increase in ingroup favoritism after negative feedback (i.e. compensation) and a decrease after positive feedback (i.e. modesty effect). In contrast, low identifiers distanced themselves from the ingroup after negative feedback and accentuated self‐ingroup similarity after positive feedback. Results are discussed in relation to a schema‐maintenance model through compensation (Seta & Seta, 1993 ) and social identity theory. Copyright © 2001 John Wiley & Sons, Ltd.     

Calculating and graphing within-subject confidence intervals for ANOVA

The psychological and statistical literature contains several proposals for calculating and plotting confidence intervals (CIs) for within-subjects (repeated measures) ANOVA designs. A key distinction is between intervals supporting inference about patterns of means (and differences between pairs of means, in particular) and those supporting inferences about individual means. In this report, it is argued that CIs for the former are best accomplished by adapting intervals proposed by Cousineau (Tutorials in Quantitative Methods for Psychology, 1, 42–45, 2005) and Morey (Tutorials in Quantitative Methods for Psychology, 4, 61–64, 2008) so that nonoverlapping CIs for individual means correspond to a confidence for their difference that does not include zero. CIs for the latter can be accomplished by fitting a multilevel model. In situations in which both types of inference are of interest, the use of a two-tiered CI is recommended. Free, open-source, cross-platform software for such interval estimates and plots (and for some common alternatives) is provided in the form of R functions for one-way within-subjects and two-way mixed ANOVA designs. These functions provide an easy-to-use solution to the difficult problem of calculating and displaying within-subjects CIs.
