Developing new treatments: on the interplay between theories, experimental science and clinical innovation

It is often argued that behaviour therapy and cognitive-behaviour therapy have a sound theoretical and experimental basis. In the early days of behaviour therapy, the learning theory accounts that were the basis of treatment made clear suggestions about the procedures that were likely to be effective in treatment. In contrast, more recent cognitive-behavioural models tend to specify targets for therapy, but not the procedures that might be optimal for changing the targets. As a consequence, a considerable amount of work has to be done in order to create an effective cognitive-behavioural treatment from a promising cognitive-behavioural model. The process by which cognitive-behavioural treatments are developed is rarely discussed in the literature. For this reason, the way in which one group has used a mixture of phenomenological, experimental and treatment development studies to create effective cognitive therapy programmes for anxiety disorders is described.     

Minority influence and social categorization: A replication

The effects of ingroup and outgroup minorities upon public and private levels of influence was examined. The results show that whilst ingroup minorities have greater influence in public, outgroup minorities can have as much, if not more influence than ingroup minorities when responses are made in private. These results are consistent with previous research and support the social identijkation model of social influence.     

On the comparison of psychological theories: A reply to professor bogartz

In response to Professor Bogartz's note (1972), which describes the application of three alternative models to data from the writers' experiment (Spiker, Croll, & Miller; 1972), the writers discuss some general considerations involved in the comparison of alternative theories. Specifically, they reject the implication that theoretically significant contributions require the comparison of alternative theories and argue that such comparisons often result in trivial or misleading conclusions. They interpret the Bogartz paper as a demonstration that his models successfully reconstitute the data from at least one type of experimental situation—the multidimensional stimulus classification task.     

Reactions to uncertainty: A comparison of three motivational theories

This study attempted to explicate some of the variables underlying preference, pleasure, and reward. In order to accomplish this, Jones's (1966, 1969) information drive theory, Berlyne's (1967, 1971, 1973, 1978) optimal arousal potential theory, Helson's (1964, 1966, 1971, 1973) adaptation-level theory, and McClelland and Clark's (1953) discrepancy hypothesis were experimentally contrasted. Subjects (316) rated the hedonic tone, perceived uncertainty, arousing properties, and interest value of two series of visual stimuli of specified uncertainty. Regression analyses revealed that immediately prior experience with stimuli varying in uncertainty affected rating of perceived uncertainty and arousing properties but had no major effects on ratings of hedonic tone and interest value. The results did not support Jones's and McClelland and Clark's models. Berlyne's model seemed to account for the affective hedonic tone and interest results, while Helson's model best explained the nonaffective perceived uncertainty and arousal data. It was concluded that nonaffective variables are affected by short-term experience with uncertainty while affective variables are not. Speculations concerning the phenomenon of interest value were then offered.Jewish Child Care AssociationThis article is based on a dissertation submitted to the New School for Social Research in partial fulfillment of the Ph.D. requirements.

A new characterization of scientific theories

First, I discuss the older “theory-centered” and the more recent semantic conception of scientific theories. I argue that these two perspectives are nothing more than terminological variants of one another. I then offer a new theory-centered view of scientific theories. I argue that this new view captures the insights had by each of these earlier views, that it’s closer to how scientists think about their own theories, and that it better accommodates the phenomenon of inconsistent scientific theories.     

Minority influence: the role of ambivalence toward the source

According to literature on social influence, a minority source may indirectly influence group members by fostering ambivalent reactions. Two studies were carried out in order to provide empirical support for this theoretical assumption. In Study 1 participants (n = 133), were exposed to a counter‐attitudinal minority message and ambivalence was manipulated by facilitating the accessibility of either ambivalent (positive and negative) or univalent (positive or negative) thoughts toward the source. We predicted and found more indirect influence in ambivalent condition than in univalent conditions. No effect of ambivalence on direct influence was found. In Study 2 (n = 127), ambivalence was measured and two possible antecedents of ambivalence, consistency of the minority and personal relevance of the topic for participants, were taken into account. Findings suggest that ambivalence mediates the effects of the two factors on indirect influence. In sum, these studies provide evidence of the importance of ambivalence in minority influence context, an early assumption that was still lacking in strong empirical support.

Social Representations,Individual and Collective Mind: A Study of Wundt,Cattaneo and Moscovici

The paper presents a discussion on the role of Social Representations in the articulation between individual and collective dimensions of mental activity. An analysis of some concepts in the works of Wundt and Cattaneo is the starting point for a discussion of the relationship between individual processes, practices, artifacts, symbolic systems and functions of Social Representations in the development of culture and individuals. In this perspective, Social Representations could be considered a space of negotiation of the meaning. The relationship between Social Representations, symbolic systems, practices and sense making involves the elaboration of the tension between continuity and innovation, which is developed through communication and practice along time in the interaction between individual and collective minds.     

Language and the young stutterer: A new look at old theories and findings

The major theories and research approaches as to the etiology and development of stuttering are reviewed from a historical perspective. Findings are drawn from different sources indicating that language deficits are an initial contributing factor and a continuing component of this disorder. Those subsets of children which constitute high-risk groups are identified. It is suggested that researchers begin investigating the underlying organic bases of stuttering and its relationship to stages of language development. Finally, clinicians are encouraged to employ a therapy program that is concerned with all areas of language, rather than emphasizing treating only the symptoms of stuttering behavior.

Minority dissent and team innovation: the importance of participation in decision making.

This study integrates research on minority dissent and individual creativity, as well as team diversity and the quality of group decision making, with research on team participation in decision making. From these lines of research, it was proposed that minority dissent would predict innovation in teams but only when teams have high levels of participation in decision making. This hypothesis was tested in 2 studies, 1 involving a homogeneous sample of self-managed teams and 1 involving a heterogeneous sample of cross-functional teams. Study 1 suggested that a newly developed scale to measure minority dissent has discriminant validity. Both Study 1 and Study 2 showed more innovations under high rather than low levels of minority dissent but only when there was a high degree of participation in team decision making. It is concluded that minority dissent stimulates creativity and divergent thought, which, through participation, manifest as innovation.     

A comparison of the multimemory and detection theories of know and remember recognition judgments

Know and remember recognition judgments were made in 2 experiments. In Experiment 1 either 3 (new, know, remember) or 4 (new, guess, know, remember) judgment alternatives were used. Also, the recognition test was either immediate, delayed 2 days, or delayed 1 week. In Experiment 2 the proportion of test items that were studied items was either .20, .50, or .80. Predictions were made from 2 multimemory theories regarding how proportions of know and remember judgments would change with these manipulations. Predictions were also made from 2 detection theories regarding the values of memory sensitivity and judgment criteria. The results supported the revised detection theory, which assumes unequal variances for studied and unstudied items, more than the multimemory theories. Furthermore, general processing tree versions of the 2 multimemory models were created including guessing processes. These extended models were shown to be inadequate in accounting for the data from the 2 experiments.     

Evoking shame and guilt: a comparison of two theories

Self-discrepancy theory associates shame with deviations from ideals that significant others hold for us and guilt with deviations from one's own moral guides. By contrast, Tangney posits that, although transgressions may engender both of these emotions, the nature of focus determines the specific reaction. Focusing upon the action committed engenders guilt, whereas focusing on the self who committed the action engenders shame. Participants recounted one of four types of discrepant actions and responded to measures of shame, guilt, anxiety, and depression. Consistent with Tangney's theorizing, across all types of discrepant actions, guilt was rated significantly higher than shame.     

The hidden impact of conspiracy theories: perceived and actual influence of theories surrounding the death of Princess Diana

The authors examined the perceived and actual impact of exposure to conspiracy theories surrounding the death of Diana, Princess of Wales, in 1997. One group of undergraduate students rated their agreement and their classmates' perceived agreement with several statements about Diana's death. A second group of students from the same undergraduate population read material containing popular conspiracy theories about Diana's death before rating their own and others' agreement with the same statements and perceived retrospective attitudes (i.e., what they thought their own and others' attitudes were before reading the material). Results revealed that whereas participants in the second group accurately estimated others' attitude changes, they underestimated the extent to which their own attitudes were influenced.     

A model-based comparison of three theories of audiovisual temporal recalibration

Observers change their audio-visual timing judgements after exposure to asynchronous audiovisual signals. The mechanism underlying this temporal recalibration is currently debated. Three broad explanations have been suggested. According to the first, the time it takes for sensory signals to propagate through the brain has changed. The second explanation suggests that decisional criteria used to interpret signal timing have changed, but not time perception itself. A final possibility is that a population of neurones collectively encode relative times, and that exposure to a repeated timing relationship alters the balance of responses in this population. Here, we simplified each of these explanations to its core features in order to produce three corresponding six-parameter models, which generate contrasting patterns of predictions about how simultaneity judgements should vary across four adaptation conditions: No adaptation, synchronous adaptation, and auditory leading/lagging adaptation. We tested model predictions by fitting data from all four conditions simultaneously, in order to assess which model/explanation best described the complete pattern of results. The latency-shift and criterion-change models were better able to explain results for our sample as a whole. The population-code model did, however, account for improved performance following adaptation to a synchronous adapter, and best described the results of a subset of observers who reported least instances of synchrony.

Minority influence: the role of the rate of majority defection and persuasive arguments

An experiment employing the Twelve Angry Men paradigm was conducted to determine the role of the rate of majority defection to the minority position and the use of persuasive arguments by the minority on minority influence. Subjects were more influenced by the minority when it provided persuasive arguments by refuting the majority viewpoint than when the minority did not. More minority influence occurred when the minority obtained majority defectors than when the minority did not. Moreover, the rate of majority defection made a difference. Minority influence was not obtained with the initial acquisition of a single defector and the significant influence that occurred with the acquisition of four defectors was not further increased by the acquisition of additional defectors. The results for the number of majority defectors were generally consistent with Tanford and Penrod's social influence model. Finally, the issue of the number of majority defectors versus the speed at which they defect is discussed. © 1998 John Wiley & Sons, Ltd.     

Semantic congruity effects and theories of the comparison process.

Two experiments requiring comparisons of point locations on the line demonstrate that the magnitude of the response-time-based congruity effect parallels the form of the macro and the micro speed-accuracy trade-off function. This is predicted from the evidence accrual class of theories but is contrary to either the propositionally based semantic coding theory or the expectancy view. Very large accuracy-based congruity effects with comparisons of point locations in the plane are evident. Congruity effects arise because the duration of each evidence accrual is increased and the quality of the information is reduced as the distance of the stimulus representations from the instruction-activated reference point increases. This evidence accrual view is extended to account for the properties of perceptual and symbolic comparisons.
