Conditioning, evaluations and cognitions: an axis of integration

When the "Golden Years" Turn Blue: Using the Healthy Aging Literature to Elucidate Anxious and Depressive Disorders in Older Adulthood

Current treatments for disorders of emotion, like pathological anxiety, are often less effective in older adults than in younger adults and have poorly understood mechanisms, pointing to the need for psychopathology models that better account for age-related changes in normative emotional functioning and the expression of disordered emotion. This article describes ways in which the healthy aging and emotion literature can enhance understanding and treatment of symptoms of anxiety and depression in later life. We offer recommendations for how to integrate the healthy aging literatures' theories and findings with psychopathology research and clinical practice, and highlight opportunities for future research.

The Relationship between Affect, Behaviour, and Cognition in Behavioural and Cognitive Treatments of Depression and Phobic Anxiety

Cognitive theories and therapies of emotional dysfunctions are based on the premise that the affective, behavioural, and cognitive response repertoires are fused and highly interdependent. Such views have been criticised with the argument that affect and cognition are relatively independent and that there is a much more direct and stronger link between affect and behaviour. In an attempt to clarify potential differences in the interplay between affect, behaviour, and cognition in unipolar depression and phobic anxiety, a quantitative review of the relative efficacy of performance-based (behavioural) versus cognitive intervention for these disorders was conducted. The relative superiority of cognitive over performance-based interventions in the treatment of unipolar depression supports the notion of a reasonably direct link between cognition and affect for this disorder providing a fairly effective pathway for treatment. On the other hand, the relative success of performance-based techniques in the treatment of phobias suggests that for these disorders the link between behaviour and affect is more direct and much stronger than the link between cognition and affect. It is concluded that the relative effectiveness of cognitive and performance-based intervention techniques depends on and points to differences in the specific type of affect-behaviour-cognition interface that underlies and is controlling depression and phobic anxiety.

Evaluative differential conditioning of disgust: a sticky form of relational learning that is resistant to extinction

The present study sought to (a) test whether autonomic (i.e., electrodermal) and evaluative conditioning can be differentially established to verbal CSs, and (b) whether extinction procedures can reliably attenuate differential conditioned evaluative responding. Thirty undergraduates underwent a 10-min adaptation period followed by three consecutive conditioning phases: habituation, acquisition, and extinction. Conditioning involved participants viewing two semi-randomly presented words on a computer monitor. During acquisition, one word (CS+) was reliably paired 12 times with the UCS (pictorial stimuli depicting bodily mutilation), whereas the remaining word (CS-) was presented 12 times and reliably followed by neutral pictures (inanimate common objects). As predicted, electrodermal and evaluative responses during acquisition were of larger magnitude to the CS+ compared to the CS-. During extinction, participants continued to evaluate the CS+ as more disgusting relative to the CS-, whereas distress and fear-related emotional ratings attenuated across extinction trials. The implications of these findings for the modifiability of disgust-based evaluative responses in specific anxiety disorders will be discussed.

Is evaluative conditioning a qualitatively distinct form of classical conditioning?

This paper contains a critical review of the claim that evaluative conditioning (EC) represents a theoretically distinct form of classical conditioning. A review of the evidence suggests that: (i) while it is claimed that EC can occur without awareness, EC studies have either adopted inappropriate statistical comparisons to demonstrate this or have failed to use the control conditions necessary to indicate that what is being measured is associative conditioning; (ii) there is no theoretical reason why conditioning without awareness might be observed in any conditioning paradigm if a relatively complex covariation assessment procedure such as that adopted in EC studies is used; and (iii) there are a variety of possible explanations for the relative resistance to extinction reported with EC, some of which allude to failure to use appropriate control conditions and others which point to specific details unique to the EC extinction procedure. Until these appropriate procedural and statistical comparisons are made, it is concluded that it is premature to assume that EC represents a form of conditioning that is theoretically distinct from other types of classical conditioning.

Acquired affective-evaluative value: conservative but not unchangeable

In a previous study on Evaluative Conditioning it was found that unlike signal-learning, evaluative learning is resistant to extinction. In the present experiment we tried to replicate and corroborate this finding. In addition, we investigated the effectiveness of a counterconditioning procedure to alter acquired evaluative value. On a within-subject base (n = 30), it was found that the mere contingent presentation of neutral with (dis)liked pictures of human faces was sufficient to change the affective-evaluative tone of the originally neutral stimuli in (negative) positive direction. Next, we replicated the finding that an extinction procedure does not have any influence on the acquired evaluative value of the originally neutral stimuli, and this even in subjects fully aware of the extinction presentations. We demonstrated the effectiveness of a counterconditioning procedure to alter acquired evaluative value, and in addition, found some evidence that awareness of the counterconditioning manipulations is not a prerequisite for its effectiveness. The theoretical consequences of these findings are phrased in terms of a fundamental distinction between signal-learning and evaluative learning, and some important implications for the behavioral treatment of affective-emotional disorders are suggested.

Agoraphobics' understanding of the development and maintenance of their symptoms

A 24-item test was devised to study the degree of understanding a group of agoraphobics had of the etiology and behavioral treatment of their symptoms before and after treatment, whether understanding was related to mode of symptom acquisition and, finally, if increase in understanding was related to treatment outcome. Clients were found to be ill-informed in areas most directly related to realistic exposure strategies, but there was no difference between those who had conditioning as opposed to cognitive acquisition histories. Changes in understanding were found to be related to outcome measures.
