A new look at cardiac defense: Attention or emotion?

The study of cardiac defense has a long tradition in psychological research both within the cognitive approach--linked to Pavlov, Sokolov, and Grahams work on sensory reflexes--and within the motivational one--linked to the work of Cannon and subsequent researchers on the concepts of activation and stress. These two approaches have been difficult to reconcile in the past. We summarize a series of studies on cardiac defense from a different perspective, which allows integration of the traditional approaches. This new perspective emphasizes a sequential process interpretation of the cardiac defense response. Results of descriptive and parametric studies, as well as those of studies examining the physiological and psychological mechanisms underlying the response, show a complex response pattern with both accelerative and decelerative components, with both sympathetic and parasympathetic influences, and with both attentional and emotional significance. The implications of this new look at cardiac defense are discussed in relation to defensive reactions in natural settings, the brain mechanisms controlling such reactions, and their effects on health and illness.

Alcohol-impaired driving is a major problem in many countries. We assessed drinking and driving and associated attitudes and legislative practices in 8282 male and 10 816 female students at universities in 23 countries. The age-adjusted prevalence of drinking and driving was 20% in men, and 7% in women. There was wide variation between countries, with the highest levels in men and women from the USA and men from South American and Mediterranean countries. Rates correlated significantly with national surveys of drinking and driving, and with national road traffic accident death rates. Drinking and driving was more prevalent in country samples in which the legal blood alcohol threshold was higher. Attitudes to drinking and driving and other aspects of hazardous driving were strongly associated with drinking and driving both within and between countries. A multi-level approach involving changes in blood alcohol laws and efforts to shift the attitudes of individuals who drink and drive is suggested by the current results.

Communalities and differences in fear potentiation between cardiac defense and eyeblink startle

This study examines similarities and differences in fear potentiation between two protective reflexes: cardiac defense and eyeblink startle. Women reporting intense fear of animals but low fear of blood or intense fear of blood but low fear of animals viewed pictures depicting blood or the feared animal for 6 s in 2 separate trials in counterbalanced order. An intense burst of white noise, able to elicit both a cardiac defense response and a reflexive startle blink, was presented 3.5 s after picture onset. Both cardiac and blink responses were potentiated when highly fearful individuals viewed fearful pictures. However, differences appeared concerning picture order. This pattern of results indicates communalities and differences among protective reflexes that are relevant for understanding the dynamics of emotional reflex modulation.

Brief report Effects of spinal cord injuries on the subjective component of emotions

Responses to a structured interview by 19 patients with spinal cord injuries (SCI) (7 women and 12 men) concerning their past (pre‐injury) and present emotions were analysed and compared with responses by 19 SCI‐free controls matched for sex, age, and education. In addition, subjects assessed the valence and arousal of 10 pleasant, 10 neutral, and 10 unpleasant pictures selected from the International Affective Picture System. The results indicate that there is no decrease in emotional experience among individuals with SCI compared with those without. For all the emotional scales (joy, love, sentimentalism, positive emotions as a whole, fear, anger, sadness, and negative emotions as a whole) the SCI group always showed either no change or an increase; this increase was significantly higher in SCI than in control subjects for sadness. No differences were observed between the two groups in the subjective assessment of the pictures. The implications of the results for the James versus Cannon controversy on the theory of emotions are discussed.
