Pain expectation,negative affect,and angry aggression

An experiment was conducted to determine if the relatively strong negative affect generated by anticipation of pain from exposure to aversive stimulation would give rise to an instigation to aggression and accompanying feelings of annoyance-irritation-anger. The 45 undergraduate women in the study were required to immerse their nondominant hand in water as they administered reward and punishment to a fellow student, supposedly as an evaluation of that person's solutions to assigned problems. In two-thirds of the cases the water temperature was unpleasantly cold, while it was much more tolerable in temperature for the remaining subjects. Half of the participants in the cold water condition and all of those in the more tolerable water temperature group has been led to expect the possibility of pain as they kept their hand in the water, whereas the remaining women (exposed to the cold water) had been alerted only to the physical sensations they would have. In accord with the findings obtained in an earlier experiment by Leventhal, Brown, Sacham, and Enquist (1979), the subjects in the cold water group expecting that they might feel pain reported experiencing the greatest discomfort. Further, consistent with Berkowitz's analysis of anger and angry aggression, these participants also reported the strongest feelings of annoyance-irritation-anger and were most punitive to the available target even though they could not attribute their discomfort to this person.     

The psychometric properties of several measures of body image

Despite the recent upsurge of interest in the construct of body image, there is relatively little information on the psychometric properties of the instruments used to measure it. This study investigated the reliability and validity of several measures of body image and compared bulimics and normals on these measures. One hundred ten normal weight females, half of whom were diagnosed as bulimic, were administered two measures of affect toward one's body, two measures of perceptions of one's entire body, and three measures of perceptions of the size of specific body sites (face, shoulders, waist, and hips). In themain, the measures provided reliable indices of body image. Examination of the correlation matrix for the measures disclosed convergence for the affective measures of body image and for all but one of the perceptual measures of body image. There was also significant covariation between the affective and the perceptual measures. The multitrait-multimethod technique was used to investigate the construct validity of the measures concerned with perceptions of the size of body sites. The multitrait-multimethod matrices disclosed substantial convergence between perceptions of face, shoulder, waist, and hip size across the three measures. However, the measure which used kinesthetic estimates of body-site size produced low reliabilities and all three of the measures showed substantial method variance. Bulimics and normals differed significantly on both the affective and the perceptual components of body image.This study is based on the first author's masters thesis. Portions of this study were represented at the 1986 meeting of the Southeastern Psychological Association. A grant to the third author from the Anclote Psychiatric Center provided support for this research project.     

Context-dependent migrations in visual word perception

In the present study we investigate the effect of context--that is, a prime--on migration errors. Migration errors, or migrations, are caused by perceptual interactions between two words in a visual display, such as line-lace. After postcuing, subjects sometimes report lane or lice, instead of the requested word line. This phenomenon has been demonstrated by previous studies. In the experiments reported here, we replicate this phenomenon. We also find that more migrations of the lane type occur (compared with lice type), when the display line-lace is preceded by a prime related to lane (but not to lice). This shows that higher order word knowledge, in the form of semantic relations between words, influences the migration phenomenon. Further, we show that the number of migration errors are not a result of only a summation of activation from the letters in the display. The method we developed to isolate context-dependent migrations also gives valuable information about the effect of contextual information on word perception.     

Processing novel compounds: Evidence for interactive meaning activation of ambiguous nouns

In three experiments, the meaning activation of ambiguous nouns in novel nominal compounds was investigated. Ambiguous nouns were unbalanced homographs occurring as the second members of the compound. Meaningful interpretations of the compounds were based on either the dominant or the subordinate meaning of the ambiguous noun. In Experiment 1, visually presented novel compounds serving as primes were followed at varying intervals by targets associatively related to distinct meanings of the ambiguous noun. In a lexical decision task, facilitation effects were found only for targets related to the meaning that was relevant for the interpretation of the compound. Experiment 2 showed that interactive activation could not be attributed to differences in semantic relatedness between the first members of compounds and targets. Experiment 3 demonstrated equal intralexical relatedness between members for both types of compounds. It is proposed that interactive activation may facilitate the interpretation of the novel compound. Compatible meaning aspects of the nouns may become more strongly activated, and incompatible meaning aspects may not become activated. The selection of meaning aspects relevant for interpretation would thereby be simplified.     

The interpretation of isolated novel nominal compounds

The lexical decision task was used to investigate interpretative processing of isolated novel compounds (noun-noun nominals). On the basis of interpretability ratings, novel compounds were classified as being of either high or low interpretability. In a lexical decision task in which novel compounds functioned as nonwords, a significant interference effect was found for compounds of high interpretability. In a naming task, no differences were found between the two types of novel compounds, but lexicalized compounds resulted in shorter latencies than did novel compounds. Novel compounds were also shown to be interpreted under conditions unfavorable to morphological decomposition, suggesting that the interpretation process is beyond strategic control by the subject. Equal semantic priming effects were obtained for members of established semantic categories and nouns of highly interpretable compounds. Interpretative processes dealing with a limited set of basic semantic relations and analogy with lexicalized compounds are discussed.     

Posttraumatic growth following pregnancy termination for fetal abnormality: the predictive role of coping strategies and perinatal grief

Background: Research about termination for fetal abnormality (TFA) suggests that it is a traumatic event with potential negative psychological consequences. However, evidence also indicates that following traumatic events individuals may experience growth. Although TFA’s negative psychological outcomes are well documented, little is known of the potential for growth following this event. Therefore, the study’s objectives were to measure posttraumatic growth (PTG) post-TFA, examine the relationship between PTG, perinatal grief and coping, and determine the predictors of PTG.

Design: An online, retrospective survey was conducted with 161 women.

Methods: Eligible participants were women over 18 who had undergone TFA. Participants were recruited from a support organisation. They completed the Brief COPE, Short Perinatal Grief Scale and Posttraumatic Growth Inventory. Data were analysed using regression analyses.

Results: Moderate levels of PTG were observed for “relating to others,” “personal strengths” and “appreciation of life.” “Positive reframing” was a significant predictor of PTG. Despite using mainly “adaptive” coping strategies, women’s grief levels were high.

Conclusions: “Adaptive” coping strategies such as, “positive reframing” are relevant to TFA. They may act as protective factors against distress and as foundations for growth, implicating that interventions such as Cognitive Behavioural Therapy, which aim to reframe women’s experience, may be beneficial.     

Dysexecutive syndrome in Parkinson’s disease: the GREFEX study

The objectives of this study were to characterize the frequencies and profiles of behavioral and cognitive dysexecutive syndromes in PD (based on validated battery and diagnostic criteria) and to develop a shortened diagnostic battery. Eighty-eight non-demented patients with a diagnosis of PD were examined with an executive validated battery. Using a validated framework, the patients’ test results were interpreted with respect to normative data from 780 controls. A dysexecutive syndrome was observed in 80.6% of the patients [95% confidence interval: 71.1–90.1]. The dysexecutive profile was characterized by prominent impairments in deduction, flexibility, inhibition and initiation in the cognitive domain, and by global hypoactivity with apathy and hyperactivity in the behavioral domain. This finding implies that patients with PD should be assessed with cognitive tests and a validated inventory for behavioral dysexecutive syndromes. A shortened battery (based on three cognitive tests and three behavioral domains) provided high diagnostic accuracy.     

Plasma BDNF is reduced among middle-aged and elderly women with impaired insulin function: Evidence of a compensatory mechanism

Brain-derived neurotrophic factor (BDNF) plays a regulatory role in neuronal differentiation and synaptic plasticity and has been linked to glucose regulation and cognition. Associations among plasma BDNF, cognition, and insulin function were explored. Forty-one participants with impaired insulin function (IIF), ranging from insulin resistance to type 2 diabetes mellitus (T2DM), were matched with 41 healthy controls on gender, age, education, and IQ. Participants received complete medical, neurological, psychiatric, and neuropsychological evaluations. IIF individuals had significantly lower plasma BDNF levels than controls, particularly females, and higher BDNF levels were associated with poorer explicit memory in IIF females, suggesting that higher levels within this group may reflect the body’s efforts to respond to damage. After accounting for age, education, and HbA1c, BDNF significantly predicted 13.1–23.5% of the variance in explicit memory in IIF women. These findings suggest that BDNF elevations within diseased groups may not always be a marker of health.     

Posttraumatic stress symptoms following childbirth and mothers' perceptions of their infants

Postpartum psychological distress can adversely affect the early mother–infant relationship; however, this has not been investigated in relation to posttraumatic stress disorder (PTSD) following childbirth. This article explores whether PTSD symptoms relating to labor and delivery are associated with mothers' early perceptions of their infant. Using labor and childbirth as the stressor criterion, 211 women were assessed at 6 weeks' postpartum for symptoms of intrusions, avoidance, and hyperarousal. Their perceptions of their infants, of mother‐to‐infant attachment, and infant behavioral characteristics also were evaluated. In sum, 3.8% of the women fulfilled full diagnostic criteria, and a further 21.3% reported clinically significant symptoms on at least one dimension of PTSD. Those meeting full or partial criteria perceived their attachment relationships to be significantly less optimal and reported more negative maternal representations in terms of their infants being less warm and more invasive. They also rated them as being temperamentally more difficult, prone to distress, and less easy to soothe. However, when the effects of depression were partialled, only the effect for perceived warmth remained. Posttraumatic stress symptoms relating to labor and delivery may adversely influence maternal perceptions of infants, with potentially adverse implications for the developing mother–infant relationship. The overlap with depressive symptoms requires further exploration.
