Extinction in human fear conditioning.

Although most extinction research is conducted in animal laboratories, the study of extinction learning in human fear conditioning has gained increasing attention over the last decade. The most important findings from human fear extinction are reviewed in this article. Specifically, we review experimental investigations of the impact of conditioned inhibitors, conditioned exciters, context renewal, and reinstatement on fear extinction in human samples. We discuss data from laboratory studies of the extinction of aversively conditioned stimuli, as well as results from experimental clinical work with fearful or anxious individuals. We present directions for future research, in particular the need for further investigation of differences between animal and human conditioning outcomes, and research examining the role of both automatic and higher-order cognitive processes in human conditioning and extinction.

A contemporary learning theory perspective on the etiology of anxiety disorders: it's not what you thought it was.

The authors describe how contemporary learning theory and research provide the basis for perspectives on the etiology and maintenance of anxiety disorders that capture the complexity associated with individual differences in the development and course of these disorders. These insights from modern research on learning overcome the shortcomings of earlier overly simplistic behavioral approaches, which sometimes have been justifiably criticized. The authors show how considerations of early learning histories and temperamental vulnerabilities affect the short- and long-term outcomes of experiences with stressful events. They also demonstrate how contextual variables during and following stressful learning events affect the course of anxiety disorder symptoms once they develop. This range of variables can lead to a rich and nuanced understanding of the etiology and course of anxiety disorders.

Attentional biases to internal and external sources of potential threat in social anxiety.

D. M. Clark and A. Wells (1995) proposed that a shift of attention inward toward interoceptive information is a central feature of social phobia. However, few studies have examined attentional biases toward internal physiological cues in social phobia. The current experiment assessed whether socially anxious individuals exhibit an attentional bias (a) toward cues for an internal source of potential threat (heart-rate information), (b) toward cues for an external source of potential threat (threatening faces) or (c) both. Ninety-one participants who were selected to form extreme groups based on a social anxiety screening measure performed a dot-probe task to assess location of attention. Results showed that socially anxious participants exhibited an attentional bias toward cues of internal, but not external, sources of potential threat.

Who sees trees before forest? The obsessive-compulsive style of visual attention.

It has been suggested that individuals with obsessive-compulsive personalities tend to focus on small local details in their surroundings, whereas histrionic individuals are characterized by more global information processing. Using the global-local hierarchical-letters paradigm, we were able to provide support for the first but not the second hypothesis. Measures related to obsessive-compulsive personality disorder were associated with excessive visual attention to small details of the hierarchical letters. Specifically, the obsessive-compulsive cognitive style was associated with local interference, which reflects the effects of distraction by to-be-ignored small details on identification of global information.

Interpersonal appraisals of emotionally distressed persons by anxious and dysphoric individuals.

Coyne [J. Abnorm. Psychol. 85 (1976a) 186; Psychiatry 29 (1976b) 28] first reported that depressed persons were negatively appraised interpersonally by interaction partners. The purpose of the current study was to replicate previous findings extending Coyne's theory to anxious individuals and to assess how anxiety and depression of the raters may affect these ratings. Anxious, dysphoric, and control participants watched a video of an actor portraying anxious, depressed, or neutral affect (n = 208). Results indicated that the actor portraying depressed affect was assessed more negatively than the actor portraying anxious affect who, in turn, was assessed more negatively than the actor portraying neutral affect. However, anxious and dysphoric participants did not differ from control participants in their ratings of the videos.

Changes in caffeine states enhance return of fear in spider phobia.

Treatment of phobias is sometimes followed by a return of fear. Animal and human research has shown that changes in external and internal contexts between the time of treatment and follow-up tests often enhance return of fear. The present study examined whether shifts in caffeine (C) state would enhance return of fear. Participants who were highly afraid of spiders (n = 43) were treated in 1-session exposure-based therapy and tested for follow-up 1 week later. Participants were randomly assigned to 1 of 4 groups and received either placebo (P) or C at treatment and follow-up sessions: CC, PP, CP, and PC. Results demonstrated state-dependent learning. Participants experiencing incongruent drug states during treatment and follow-up (CP and PC) exhibited greater return of fear than those experiencing congruent drug states (CC and PP).

Phobias and preparedness: the selective, automatic, and encapsulated nature of fear.

We describe evidence for an evolved module for fear elicitation and fear learning with four primary characteristics. First, it is preferentially activated by stimuli related to survival threats in evolutionary history. Thus, fear-relevant stimuli lead to superior conditioning of aversive associations compared with fear-irrelevant stimuli. Second, the module is automatically activated by fear-relevant stimuli, meaning that fear activation occurs before conscious cognitive analysis of the stimulus can occur. Third, the fear module is relatively impenetrable to conscious cognitive control, and fear conditioning with fear-relevant stimuli can occur even with subliminal conditioned stimuli. Fourth, the amygdala seems to be the central brain area dedicated to the fear module. Finally, we propose that there are two levels of fear conditioning, with an emotional level that is relatively independent of the cognitive contingency level, each mediated by different brain areas.

Born to fear: non-associative vs associative factors in the etiology of phobias.

Poulton and Menzies (Behaviour Research & Therapy 40 (2001) 127-149) review two lines of evidence as supporting a non-associative pathway to the origins of "evolutionary relevant phobias". First, in retrospective studies of mode of onset some recall they have always had this fear. We review here solid evidence that retrospective recall is notoriously unreliable. Second, they note as many nonphobics recall relevant associative learning experiences as do phobics. We argue such studies are very inconclusive because they fail to consider many experiential and personality vulnerability (and invulnerability) factors that strongly impact the outcome of any putative learning experience. Their argument also does not explain the transition from developmental fears to phobias that is central to their thesis. Overall, we call for major methodological improvements in this area, in the context of theoretical developments pointing to interacting vulnerability and invulnerability factors.
