The Death of Resistance

For any conceptual distinction to be useful ( 5 ) within the field of family therapy, it needs to lead to some clear answers to the question: What does this distinction mean for clinical practice? The distinction between (a) the family-as-a-system, and (b) family-therapy-as-a-system leads to a clinical perspective, or stance, that includes a focus on changing. Once this focus is clear, the therapist can help to create the expectation of changing and consequently promote changing. That is, techniques can be developed using positive feedback loops. ¹ 1 It is important to remember throughout this essay that “positive” and “negative feedback loops,”“deviation-amplifying,”“deviation-counteracting processes,” etc., are just heuristic devices or metaphors. Human systems do not have such things. Human systems are described by an observer “as if.”
Moreover, this distinction leads to a therapeutic stance in which not changing is a surprise.     

The effects of electroconvulsive shock on the action of a reinforcing stimulus

Three experiments sought to evaluate the effect of electroconvulsive shock on the action of a reinforcing stimulus. In all experiments behavior was maintained on a 2 min variable interval schedule for food reinforcement. Foot shock at the termination of a buzzer stimulus served as the reinforcing stimulus for conditioned suppression during the ensuing buzzer interval. Omission of foot shock at the termination of the buzzer stimulus was followed by normal responding (no conditioned suppression) during the next buzzer interval. In Exp I electroconvulsive shock followed foot shock at varying time intervals. In the first subsidiary experiment electroconvulsive shock followed an unreinforced buzzer stimulus at varying time intervals. In the second subsidiary experiment electroconvulsive shock followed foot shock at varying time intervals and an additional buzzer stimulus was sounded between the termination of foot shock and the onset of electroconvulsive shock. These three experiments demonstrated that electroconvulsive shock invariably abolished the effects of the reinforcing stimulus if it followed conditioning by no more than 10.0 sec and never had an effect if it followed conditioning by 12.5 sec or more; electroconvulsive shock was not acting as a reinforcing stimulus in this situation.     

Early development of letter specialization in left fusiform is associated with better word reading and smaller fusiform face area

A functional region of left fusiform gyrus termed “the visual word form area” (VWFA) develops during reading acquisition to respond more strongly to printed words than to other visual stimuli. Here, we examined responses to letters among 5‐ and 6‐year‐old early kindergarten children (N = 48) with little or no school‐based reading instruction who varied in their reading ability. We used functional magnetic resonance imaging (fMRI) to measure responses to individual letters, false fonts, and faces in left and right fusiform gyri. We then evaluated whether signal change and size (spatial extent) of letter‐sensitive cortex (greater activation for letters versus faces) and letter‐specific cortex (greater activation for letters versus false fonts) in these regions related to (a) standardized measures of word‐reading ability and (b) signal change and size of face‐sensitive cortex (fusiform face area or FFA; greater activation for faces versus letters). Greater letter specificity, but not letter sensitivity, in left fusiform gyrus correlated positively with word reading scores. Across children, in the left fusiform gyrus, greater size of letter‐sensitive cortex correlated with lesser size of FFA. These findings are the first to suggest that in beginning readers, development of letter responsivity in left fusiform cortex is associated with both better reading ability and also a reduction of the size of left FFA that may result in right‐hemisphere dominance for face perception.     

The importance of normative beliefs to the self-prophecy effect

Asking people to predict whether they will undertake a target behavior increases their probability of performing that behavior. Now referred to as the self-prophecy effect, this phenomenon has been demonstrated across several contexts. Although theoretical explanations for the effect have been offered, empirical evidence for proposed accounts is sparse. The current research tests the theoretically relevant precondition for the effect that normative beliefs--evaluations of what is socially desirable or appropriate--underlie manifestation of the self-prophecy effect. Results of 2 experiments for different behaviors indicate that the act of making a prediction is most effective when normative beliefs are strong. Implications of these findings are discussed in relation to theoretical explanations for the effect and successful use of self-prophecy to promote socially desirable behaviors.
