Anger and denial as predictors of cardiovascular reactivity in women

The relationship between behavioral and physiological reactivity and cardiovascular disease has been extensively researched in men, indicating that the expression of anger may be a contributory factor in the development of coronary heart disease. Few studies, however, have focused on women. Among these, women generally have been found to be less reactive to laboratory tasks than men. In the present study, 45 women aged 19–21 years were selected to represent three groups—(1) low anger/low denial, (2) high anger/low denial, and (3) low anger/high denial—based on their scores on the State-Trait Anger Expression Inventory and the Marlowe-Crowne Social Desirability Scale. Subjects received three conditions: (1) no feedback, (2) error feedback without observer present, and (3) error feedback with observer present. As hypothesized, women who reported a high level of denial and low anger exhibited elevated stress-related reactivity. The results are suggestive of a subgroup of highly reactive women not previously identified within the literature. The hypothesis that all groups would display greater reactivity in a condition providing error feedback with observation was not supported.This study was supported by a research grant to Carol S.

Development of conditional and equivalence relations without differential consequences

Two experiments were conducted to establish conditional stimulus relations without differential consequences and to test for the emergence of other relations. In Experiment 1, 3 adults responded to match-to-sample displays in which sample-comparison pairs were constant while the second comparison presented with each pair changed periodically across trials. No differential consequences followed any comparison selections. All subjects learned conditional relations between constant samples and comparisons, but results of tests for transitivity in those relations were equivocal. In Experiment 2, 4 children were given unreinforced training and testing similar to that provided to the adults in Experiment 1, with procedural refinements. One child learned conditional relations and demonstrated emergent relations that confirmed the development of two four-member equivalence classes. Another child learned the conditional relations but did not demonstrate any emergent relations reliably. A 3rd child, after reinforced training on two conditional relations, learned four new conditional relations without differential consequences and demonstrated symmetry but not equivalence in the trained relations. The 4th child did not learn the conditional relations. These findings emphasize the importance of careful construction of tests for stimulus equivalence and suggest a need for critical analyses of the apparent emergence of untrained stimulus relations on unreinforced tests that has been observed in several stimulus equivalence studies.     

Tracing response parameter preparation strategies using transition times

Latencies were measured using a modified four-choice reaction time (4-CRT) test procedure; the responses comprised forward and backward displacements of left- and right-hand levers. Two stimuli were presented, separated by an interval (ISI) of 25, 165, 415 or 815 msec. S1 designated which response should be readied; and on 62% of occasions, S2 indicated that the prepared response should be executed immediately (same trials). During transition trials, S2 specified which one of the alternative responses should be substituted. Same conditions produced significantly shorter reaction times. Transition latencies varied depending on the modification required: changing direction proved easier than changing either hand or hand and direction. This is compatible with a response coding strategy in which limb is designated before direction. Latencies and exchange function analyses that preparations were discontinued after response selection; even at the longest ISI, there was no convincing evidence of preparatory motor programming.     

Embarrassing age spots or just plain ugly? Physical attractiveness stereotyping as an instrument of sexism on american television commercials

Frequencies of attractiveness-based messages were examined on 4,294 network television commercials. As expected, attractiveness statements appeared to be associated more with food and drink and personal care ads, and with female performers and with male voice-overs. Implications of an association of women and attractiveness on television are explored.An earlier version of this paper was presented at the annual meeting of the Southeastern Psychological Association, Atlanta, March 1983.     

Perspective taking in children's narratives about jealousy

This study explored relationships between perspective‐taking, emotion understanding, and children's narrative abilities. Younger (23 5‐/6‐year‐olds) and older (24 7‐/8‐year‐olds) children generated fictional narratives, using a wordless picture book, about a frog experiencing jealousy. Children's emotion understanding was assessed through a standardized test of emotion comprehension and their ability to convey the jealousy theme of the story. Perspective‐taking ability was assessed with respect to children's use of narrative evaluation (i.e., narrative coherence, mental state language, supplementary evaluative speech, use of subjective language, and placement of emotion expression). Older children scored higher than younger children on emotion comprehension and on understanding the story's complex emotional theme, including the ability to identify a rival. They were more advanced in perspective‐taking abilities, and selectively used emotion expressions to highlight story episodes. Subjective perspective taking and narrative coherence were predictive of children's elaboration of the jealousy theme. Use of supplementary evaluative speech, in turn, was predictive of both subjective perspective taking and narrative coherence.     

Reduced activation of left orbitofrontal cortex precedes blocked vocalization: A magnetoencephalographic study

While stuttering is known to be characterized by anomalous brain activations during speech, very little data is available describing brain activations during stuttering. To our knowledge there are no reports describing brain activations that precede blocking. In this case report we present magnetoencephalographic data from a person who stutters who had significant instances of blocking whilst performing a vowel production task. This unique data set has allowed us to compare the brain activations leading up to a block with those leading up to successful production. Surprisingly, the results are very consistent with data comparing fluent production in stutterers to controls. We show here that preceding a block there is significantly less activation of the left orbitofrontal and inferiorfrontal cortices. Furthermore, there is significant extra activation in the right orbitofrontal and inferiorfrontal cortices, and the sensorimotor and auditory areas bilaterally. This data adds weight to the argument forwarded by Kell et al. (2009) that the best functional sign of optimal repair in stutterering is activation of the left BA 47/12 in the orbitofrontal cortex.Educational objectives: At the end of this activity the reader will be able to (a) identify brain regions associated with blocked vocalization, (b) discuss the functions of the orbitofrontal and inferior frontal cortices in regard to speech production and (c) describe the usefulness and limitations of magnetoencephalography (MEG) in stuttering research.
