Is dissonance phenomenologically aversive?

This study examined whether dissonance is, phenomenologically, an aversive state. Experimental subjects were induced to write counterattitudinal essays under a high-choice condition. One group of subjects was led to believe that a pill, which they had just taken in the context of a separate experiment, would cause them to feel pleasantly excited. A second group was led to believe that the pill would make them feel tense. A third group was given no information about the pill's potential side effects, while a fourth group expected to have no side effects at all. In this last condition, the results yielded the usual dissonance effect: subjects stated attitudes more congruent with the essay than did subjects in a survey control condition. When subjects were given an opportunity to attribute their arousal to an arousing, but nonaversive pill (i.e., the pleasant excitement condition), this effect was unchanged. In contrast, when subjects could attribute their arousal to an aversive pill (i.e., in the tensè and the no information conditions), this effect was virtually eliminated. These results are consistent with the notion that dissonance is an aversive state and that subjects will seize, when possible, an external attribution for this state.     

Prior exercise of freedom and reactance

A communication that contains a particularly strong intent to influence caneasily lose persuasive impact or even bring about a “boomerang” effect. Such “boomerang” phenomena have often been attributed to “psychological reactance”, a motivational state created when freedoms are threatened or usurped. The first experiment reported here examined two factors that inhibited reactance effects. (A) The more that subjects were in initial disagreement with the communicator, the less likely they were to respond with boomerang change to a high pressure communication. (B) Among subjects who initially agreed with the communicator, a successful blocking of reactance effects was produced by asking them to write a short precommunication essay taking a position contrary to the communication. This latter effect was replicated in Experiment II.     

Effects of metronome-conditioned relaxation,metronome-induced relaxation,and progressive muscle relaxation on insomnia

Although several controlled studies have indicated that relaxation can be effectively employed in the treatment of insomnia (Borkovec and Fowles, 1973; Steinmark and Borkovec. 1974; Haynes et al., 1974), the relaxation training procedures thus far utilized have typically necessitated several hours of therapist-client contact. The possibility of a more efficient relaxation procedure for treating insomniacs suggests an attractive alternative to the tense-relax instructions of progressive muscle relaxation (Jacobson, 1938). Brady (1973) has reported that the sound of a metronome set at 60 beats per min is inherently relaxing, and although he has only reported on the effects of the metronome when paired with verbally-induced relaxation (both general suggestions of relaxation and instructions to tense and relax successive muscle groups), he has successfully employed this technique in the treatment of borborygmi (rumbling noises in the abdomen) and essential hypertension (Brady, 1973; Brady, Luborsky and Kron, 1974). If the sound of the metronome alone, which would require minimal therapist-client contact, is sufficient to induce relaxation, the efficiency with which relaxation can be achieved in the treatment of insomnia, as well as other tension-related disorders. may be greatly enhanced.The present study was designed to assess the relaxation-inducing properties of (a) Brady's metronome-conditioned relaxation (metronome plus verbal relaxation instructions), (b) progressive muscle relaxation and (c) metronome-induced relaxation (the sound of a metronome alone) in the treatment of insomnia. In order to provide an evaluation of the effectiveness of relaxation techniques with a broader population than was sampled in previous investigations of this nature, this study included employed adults as well as college students in the subject pool. In addition to its implications for treating insomnia, this study was designed to yield an independent test of the hypothesis that a 60 beat per min metronome sound has the capacity by itself to induce relaxation.     

Acquisition of a free-operant-appetitive response in pigeons as a function of prior experience with response-independent food

Deficits in learning to escape from electric shock following exposure to response-independent preshocks have frequently been reported and have been referred to as learned helplessness. Experiments were conducted in order to determine whether a phenomenon similar to learned helplessness could be induced in appetitive free-operant procedures with pigeons. Subjects received preliminary training under one of the following conditions; protracted exposure to response-dependent grain presentations (key pecking), protracted exposure to response-independent grain deliveries, or short-term hopper training. Subjects were then tested for acquisition of a treadle-pressing response which was the only means of access to grain in the experimental chamber. The acquisition of the treadle-pressing response was retarded following protracted exposure to response-independent grain deliveries and the degree of this retardation was related to the complexity of the response-reinforcer contingency.     

Resistance to punishment as a function of intensity and frequency of prior punishment experience

Rats with a history of intermittent punishment have been found to persist in the face of continuous punishment. It was predicted from an extension of frustration theory to punishment that increasing the intensity or frequency of intermittent punishment would increase persistence to high fear elicited by continuous punishment. Two experiments, employing 310 rats, verified this prediction for both intensity and frequency manipulations but indicated rather narrow boundary conditions for their effects.     

Relation between intelligence and short-term memory

Several prior studies have concluded that the correlation between IQ and STM depends on differences in encoding or rehearsal strategies. Low IQ subjects use less effective strategies than high IQ subjects. One basis for these conclusions is that IQ exerts its greatest influence on the recall of early items in to-be-remembered lists, having little effect on the recall of recency items. The present study measured IQ/STM correlations in children, using probed serial recall of supraspan digit lists. The results showed the predictive power of IQ to range from a maximum in the case of recall for recency items to practically zero in the case of primacy items. Several explanations for the data are discussed, taking account of the possible roles of individual differences in rehearsal, in item persistence, and in the ability to access specified information in a short-term store.     

Some conditions that affect admissions of attitude change

Previous research has shown yielders to persuasive communications to be negatively evaluated by observers of the persuasion but positively evaluated by the persuaders. Resisters of persuasion, on the other hand, are evaluated positively by observers but negatively by the initiators of the persuasive effort. Two studies were conducted to determine (a) whether individuals are aware of the differing evaluations of yielders and resisters by persuaders and observers and (b) the extent to which targets of influence attempts strategically employ this information to enhance their images in the eyes of others. Experiment 1, a role-playing study, demonstrated that targets of persuasive appeals are cognizant of the pattern of evaluations provided to yielders and resisters by persuaders and observers. Experiment 2 indicated that targets' public reports of attitude change were shaped so as to produce the most positive evaluations from the audience to those reports. The greatest stated influence occurred in the sole presence of the persuasive agent, an intermediate amount of stated change occurred when both persuader and observer were present, and still less occurred in the sole presence of an observer to the influence attempt. The results of anonymous, private measures of change paralleled in pattern those of the publicly admitted change, but were not significant.     

Auditory processing of relational information by young infants

The ability of 5-month-old infants to process relational information was assessed by means of a habituation-dishabituation paradigm with cardiac deceleration as the response measure. Infants were first habituated to a six-tone pattern and then shifted either to a transposition of the standard pattern or to a control pattern which comprised the elements of the transposed pattern in scrambled order. Dishabituation was not evident in the case of the transposed group but was clearly evident for the control group. These results indicate that infants can process relational information from tonal patterns.
