Induced mood and preschoolers' behavior: isolating the effects of hedonic tone and degree of arousal

A circumplex model of emotion was used to examine the role of hedonic tone and degree of arousal in the effects of induced mood on children's persistence behavior. A total of 45 preschool children were asked to describe and think about either exciting, calm, or sad experiences and then perform a persistence task. Heart rate was continuously recorded throughout the session. Observers' ratings of facial expressions and parents' ratings of the experiences provided convergent validation of the induction procedure. Children in the excited induction were rated as displaying facial expressions and generating situations that were high on both pleasure and arousal. The facial expressions and situations of those in the calm induction were also rated as positive, but less arousing, whereas those in the sad induction were rated as low on both. Concurrent heart rate recordings showed differential effects of the mood condition on autonomic arousal during the period when the children were generating the affect-inducing situations. These effects dissipated shortly after the beginning of the concentration phase of the induction procedure. Subsequent performance on a persistence task indicated that higher levels of arousal increased the amount of work completed, whereas higher levels of pleasure did not. Differential levels of autonomic arousal were displayed during the persistence task. These findings validate two important elements of the experimental design: excited versus calm states induce similar levels of pleasure but different levels of arousal, and calm versus sad states induce similar levels of arousal but different levels of pleasure. In previous research, hedonic tone and degree of arousal have often been confounded.(ABSTRACT TRUNCATED AT 250 WORDS)     

Increased cardiac awareness in panic disorder.

We investigated cardiac perception in panic disorder with both self-report and objective measures. In Study 1, 120 patients with panic disorder, 86 infrequent panickers, and 38 patients with other anxiety disorders reported greater cardiac and gastrointestinal awareness than 62 normal control subjects. Subjects with panic attacks reported greater cardiac awareness, but not gastrointestinal awareness, than those with other anxiety disorders. Studies 2 and 3 included a test of heart rate perception in which subjects silently counted their heart-beats without taking their pulse. In Study 2, 65 panic disorder patients showed better performance than 50 infrequent panickers, 27 patients with simple phobias, and 46 normal control subjects. No group differences were found in ability to estimate time intervals. In Study 3, 13 patients with panic disorder and 15 with generalized anxiety disorder showed better heart rate perception than 16 depressed patients.     

In the mood for adaptation: how affect regulates conflict-driven control

Cognitive conflict plays an important role in tuning cognitive control to the situation at hand. On the basis of earlier findings demonstrating emotional modulations of conflict processing, we predicted that affective states may adaptively regulate goal-directed behavior that is driven by conflict. We tested this hypothesis by measuring conflict-driven control adaptations following experimental induction of four different mood states that could be differentiated along the dimensions of arousal and pleasure. After mood states were induced, 91 subjects performed a flanker task, which provided a measure of conflict adaptation. As predicted, pleasure level affected conflict adaptation: Less pleasure was associated with more conflict-driven control. Arousal level did not influence conflict adaptation. This study suggests that affect adaptively regulates cognitive control. Implications for future research and psychopathology are discussed.     

Do Animals Have Souls? An Evolutionary Perspective

This paper addresses the question of whether animals have souls and the ability to experience God after death within the limitations of their nature. Plausible explanations for the natural origin of life and for the development of subsequent complexity are increasingly being advanced by molecular biologists. Christian tradition and scholasticism teach that the human body is animated by the soul which is the agent of vital activities. This teaching is incompatible with the claim for a natural origin for life. At some stage in the evolution of chordates and cephalopods a sense of self‐awareness and an ability to distinguish between pleasure and the absence of pleasure would have arisen permitting the potential for ensoulment. The premise that evolution was gradual but ensoulment was discontinuous predicates the irrational conclusion that for one generation the parents were animals without souls and their children humans, made in the image of God, and with souls. Biological gradualism is incompatible with a sudden ensoulment dichotomy both in the evolutionary history of humans and for a maturing foetus, human or animal. Gradualism must apply to both body and soul. A Christian interpretation of physicalism, however, provides an alternative to dualism and resolves the paradoxes and difficulties relating to animals.     

Emotional responses in spider fear are closely related to picture awareness

Theories of emotion propose that responses to emotional pictures can occur independently of whether or not people are aware of the picture content. Because evidence from dissociation paradigms is inconclusive, we manipulated picture awareness gradually and studied whether emotional responses varied with degree of awareness. Spider fearful and non-fearful participants viewed pictures of spiders and flowers at four levels of backward masking while electrodermal activity and heart rate were measured continuously. Recognition ratings confirmed that participants’ picture awareness decreased with masking. Critically, effects of spider fear on emotion ratings and heart rate also decreased with masking. These findings suggest that effects of spider fear on emotion ratings and heart rate are closely related to picture awareness.

Awareness of the response after feedback training for changes in heart rate and sudomotor laterality

What is the relation between the ability to control visceral responding on a biofeedback task and the ability to report behaviors actually contributing to this performance? Subjects received biofeedback training for unidentified visceral responses and then gave written reports about what they had done to control the feedback displays. Independent judges were given these reports and, on the basis of knowledge about activities known to contribute to visceral activity, were asked to determine the visceral responses for which the subjects had been trained. The reports of subjects who succeeded at bidirectional control of heart rate (Experiment 1) or sudomotor laterality (Experiment 2) showed awareness of behaviors related to feedback as assessed by this procedure, whereas the reports of subjects who failed at bidirectional control did not. Subsequent experiments indicated that these results did not depend on a learning strategy that might have been specific to the initial studies. These findings call into question the view that people are unaware of what they have done to produce the response after training on biofeedback tasks. Earlier studies reporting lack of awareness in biofeedback are discussed in light of factors that affect the measurement of biofeedback learning and response awareness.     

Epinephrine,Arousal, and Emotion: A New Look at Two-factor Theory

Ever since William James, psychologists of emotion have tended to view affective states as intrinsically conscious. We argue that nonconscious affect also exists, and focus specifically on the possibility of unconscious "liking". We present evidence that positive and negative affective reactions can be elicited subliminally, while a person is completely unaware of any affective reaction at all (in addition to being unaware of the causal stimulus). Despite the absence of any detectable subjective experience of emotion, subliminally induced unconscious "liking" can influence later consumption behaviour. We suggest that unconscious "liking" is mediated by specific subcortical brain systems, such as the nucleus accumbens and its connections. Ordinarily, conscious liking (feelings of pleasure) results from the interaction of separate brain systems of conscious awareness with those core processes of unconscious affect. But under some conditions, activity in brain systems mediating unconscious core "liking" may become decoupled from conscious awareness. The result is a genuinely unconscious emotion.     

The starting line and the promotion of EU anti-discrimination legislation: The role of policy oriented research

This article looks back at the process that led to the adoption of European legal measures against racial discrimination and the role policy-oriented research has played. It also looks briefly ahead to the coming years when these instruments will be incorporated into the laws of the current and future EU member states. Research played an important role in the policy debates that led to the adoption of the Racial, Equality Directive. Research was strategically used to raise awareness and to formulate legislative proposals. The stakeholders in the debate, whether they were official institutions or non-governmental organizations, used existing research, commissioned new research, or undertook research themselves.

The effects of mood upon imaginal thought

The effects of mood upon imaginal thought were explored with a highly trained undergraduate female hypnotic subject. She was hypnotically programmed to experience free-floating anxiety or pleasure in varying degrees just before the exposure of combinations of three Blacky Pictures, and to produce dreamlike imagery in response to the Blacky stimuli while under sway of the mood. Data from 98 dream trials, separated by amnesia, indicated that the affective states clearly influenced imaginal processes. Blind ratings by a psychoanalyst showed the anxiety moods to be more closely associated with primary-process features characteristic of nocturnal dreams, whereas pleasure had a relatively higher incidence of daydreamlike ratings. Empirical analysis of themes yielded significant relationships of anxiety to physical injury to the self and verbal aggression toward others; pleasure was associated with circular movements and overt sex themes.

The influence of sphincter control and genital sensation on body image and gender identity in women.

The development of one aspect of feeling female is hypothesized to account for certain phenomena in the treatment of young women patients. Fear of loss of genital pleasure experienced as contractions of the anal and genital-urinary sphincters is seen as the central issue in conflicts manifested in genital, oral, and anal modalities. It is suggested that the female's awareness of her genital arises from the generalization of sphincter sensation in the little girl, which is then represented in the body image. The body image is postulated as a link between genital pleasure and the valuing of femininity.     

Development of physiological response patterns concomitant with the learning of voluntary heart rate control.

Thirty-six male undergraduate students were instructed to raise or lower heart rate in a multiple-session biofeedback experiment. Systolic and diastolic blood pressure, frontalis electromyographic activity, and skin conductance level were simultaneously recorded throughout biofeedback training. Principal axes factor analyses showed that physiological response patterning concomitant with the development of heart rate control was different early in training (Training Session 1) than it was late in training (Training Session 4) for both speeding and slowing conditions. These results indicate that different heart rate control strategies were used by the subjects early and late in training. The factor patterns also indicated a tendency for greater heart rate response specificity as training progressed for both speeding and slowing. Heart rate speeding sessions were also found to be associated with a significant increase in perceived state anxiety as measured by the State-Trait Anxiety Inventory. No significant change in perceived anxiety state, however, was associated with heart rate slowing.     

Morphological awareness predicts the growth rate of Chinese character reading

In this longitudinal study, we assessed 88 Hong Kong Chinese typically developing kindergarteners' Chinese character reading accuracy four times with 6‐month intervals over 1.5 years with the first testing point in the fall of the second year of kindergarten (K2), during which morphological awareness, phonological awareness, orthographic awareness, visual–spatial relationships, and nonverbal IQ were tested (Time 1). The latent growth curve modeling showed that reading development in Chinese of typically developing kindergarteners followed a cumulative linear trajectory, suggesting that children with higher initial reading ability develop reading ability at a faster rate. Additionally, morphological awareness at K2 positively and uniquely predicted a linear growth pattern of character reading between K2 and K3 over 1.5 years, a period in which formal teaching and learning Chinese takes place in Hong Kong. Contributing to the literature, these findings highlighted the unique significance of morphological awareness in the growth rate of reading: Typically developing children with better early morphological awareness tend to have a higher initial point of reading ability and, more importantly, a faster growth rate, resulting in a wider discrepancy of developmental outcomes between low‐ and high‐ performers. The results suggest that greater attention should be focused on the development of morphological awareness in early readers, given its salient role in Chinese reading development.     

Rhythmic organization of heart rate in breast-fed and bottle-fed newborn infants

Heart rates and behavioural states of 14 breast-fed and 14 bottlefed newborn infants were assessed every 30 seconds for 2 continuous hours. The 240 observations of heart rate were treated as time-series data and spectrum-analysed for behavioural rhythmicities. Of the 28 infants, 25 showed reliable cycles in heart rate; 22 of the 25 infants showed a dominant frequency with a 30–60 min periodicity, one that approximates the basic-rest activity cycle (BRAC). In addition to this basic cycle, additional higher frequency cycles in long-term heart rate variability were evident in the spectra of many infants. Breast-fed newborns had greater numbers of reliable cycles in heart rate than bottle-fed newborns. Further, breast-fed newborns had lower overall mean heart rates and lower mean heart rates in Quiet and Active Sleep states than bottle-fed newborns. Bottle-fed newborns were observed more often in Quiet Sleep than breast-fed newborns. Without knowledge of the specific mechanisms causing these behavioural differences, the results of this study suggest that the context in which breast-feeding occurs results in a more complex and energy-efficient pattern of behavioural organization than the context of bottle-feeding.     

Phonemes, Rimes, and the Mechanisms of Early Reading Development

Our paper (Hulme, et al., 2002) provides further evidence that phoneme-level skills are better predictors of children's early progress in learning to read than are onset-rime skills. The commentaries on our paper raise a number of issues including which variables (such as vocabulary knowledge and rime ability) need to be controlled in order to demonstrate a specific relationship between phoneme-level skills and reading ability and whether prereaders are capable of performing phonemic awareness tasks and the factorial structure of phonological skills. None of the commentaries, however, casts any doubt on our basic conclusion that phoneme-level skills are better predictors of early reading skills than are onset-rime skills.     

Individual differences in imagery vividness and voluntary heart rate control

Dispositional differences in imagery vividness may account partially for the large individual differences in learning heart rate control. Based upon scores on the Betts QMI Vividness of Imagery Scale, 10 subjects were defined as a high imagery group and 10 subjects were defined as a low imagery group. All subjects were instructed to try to alter their heart rate as indicated by appropriately labeled lights. Six increasing, six decreasing and six rest, 45-sec trials were presented. During the trials, visual heart rate feedback was provided by a digital voltmeter. The dependent measure was computed by subtracting the mean of the last 5 beats of a 15-sec intertrial interval from the mean rate per trial. Results indicated that subjects were able to significantly raise and lower heart rate relative to rest trials. Furthermore, high imagery subjects demonstrated significantly larger changes than low imagery subjects on increase trials but not on decrease trials. Subjects in both groups typically reported using more specific images for increasing heart rate than for decreasing heart rate. These data suggest that dispositional differences in imagery vividness may have contributed to the differential performance of the two groups during the increase task.
