Acting-out: its functions within analytic group psychotherapy and its transformation into dreams

In group processes, acting-out has diverse functions, all of them equally important. It has an intrapsychic, interpersonal, and group dynamic function. Not only may it be understood as a form of resistance, but also in its communicative and reparative potential. The authors investigate the thesis that acting-out also contains the seed for change, thus helping patients divest themselves of pathological behavior. Using a group process as an example, this article shows how boundaries can be drawn between past and present experiences while using the communicative and reparative functions of acting-out. Unconscious psychodynamics can then be transformed from acting-out into dreams.     

Locus of inhibition in the masked priming of response alternatives

Masked prime stimuli presented immediately before target stimuli in a choice reaction task give rise to behavioral costs when the primes and the target stimuli are mapped to the same response and result in benefits when they are mapped to opposite responses. Researchers assume that this negative compatibility effect reflects inhibitory processes in the control of perceptuomotor links. The authors investigated whether the inhibition operates at the level of abstract central codes or at effector-specific motor stages. In 2 experiments (N = 8 participants in each), left or right hand or foot responses were required to target stimuli that were preceded by masked arrow primes mapped to the same response side as the target stimuli in compatible trials and to the opposite response side in incompatible trials; the primes were irrelevant in neutral trials. In Experiment 1, when the masked primes determined both response side and modality, there was no transfer of negative compatibility effects across response modalities. That finding is inconsistent with a central abstract locus of inhibition and suggests that inhibition operates at effector-specific motor stages. In Experiment 2, primes conveyed only response side information but left response modality uncertain, and negative compatibility effects were elicited for both hand and foot responses, suggesting that partially informative masked primes can trigger a parallel activation and subsequent inhibition of response processes within separate effector systems.     

Experiences of longing in Norwegian and Swedish 4- and 5-year-old children

Longing can be defined as a blend of the primary emotions of happiness and sadness. These primary emotions are experienced very early by children, and the meanings of the words happiness and sadness are also known by children early in their verbal development. To find out at what age children are able to understand and use the more developed concept of longing, the authors interviewed 74 preschoolers (4- and 5-year-olds) in Norway and Sweden about their experiences of longing. Chi-square analyses showed age and sex differences in knowledge of the concept, and some differences between categories of longing were also significant. Results showed that young children's ability to understand and use the concept of longing appears to be limited and that girls seem to mature earlier in this respect than boys do.     

Personality,mental distress,and risk perception in subjects with multiple chemical sensitivity and toxic encephalopathy

Personality, mental distress, and risk perception were assessed in (a) cases of multiple chemical sensitivity (MCS; n = 17), (b) chemically intolerant toxic encephalopathy cases (TE), type 2A (n = 31) and 2B (n = 26), and (c) healthy referents (n = 200). MCS cases showed elevated mental distress scores on the Depression, Interpersonal Sensitivity, Global Severity Index, and Somatization scales in the Symptom Checklist 90 (SCL-90). In the Karolinska Scales of Personality (KSP) the MCS group showed an elevation only on the Psychasthenia scale. Both TE groups showed elevations across the KSP anxiety scales Muscular Tension, Psychasthenia, and Somatic Anxiety. TE type 2B subjects also showed elevations on the Irritability and Indirect Aggression scales. However, neither MCS nor TE groups showed deviating personality characteristics in the Meta Contrast Technique test. Similarly, none of the groups deviated from referents in a risk perception inventory.     

Response styles in affect ratings: making a mountain out of a molehill

Ratings of affect words are the most commonly used method to assess pleasant affect (PA) and unpleasant affect (UA). The reliance on self-reports would be problematic if affect ratings were heavily influenced by response styles. Several recent publications have indeed suggested (a) that the influence of response styles on affect ratings is pervasive, (b) that this influence can be controlled by variations of the response format using multitrait-multimethod models, and (c) the discriminant validity of PA and UA is spurious. In this article, we examined the evidence for these claims. We demonstrate that (a) response styles have a negligible effect on affect ratings, (b) multiple response formats produce the same results as a single response format, and (c) the discriminant validity of PA and UA is not a method artifact. Rather, evidence against discriminant validity is due to the use of inappropriate response formats that respondents interpreted as bipolar scales.     

A Rorschach study of oral dependence in alcoholics and depressives

Despite the strong association between alcoholism and orality in psychoanalytic theory, use of the Rorschach Inkblot Test to provide empirical support for such a link has yielded decidedly mixed results. However, Masling's Rorschach Oral-Dependency (ROD) scale has shown twice that people with alcoholism give more oral-dependent responses on the Rorschach than matched comparison groups (Bertrand & Masling, 1969; Weiss & Masling, 1970), which is supportive of classical analytic theory. In this study, we investigated alcohol groups, depression groups, and "normal" undergraduates with the ROD scale and found that the 2 clinical groups produced higher ROD scores than the undergraduates. In addition, recent studies by Duberstein and Talbot (1993) and Fowler, Hilsenroth, and Handler (1996) provide evidence for an object relations model of dependency that suggests that a balance between anaclitic dependence and complete independence, in which dependency needs are acknowledged but are not overwhelming, is most adaptive. This model of dependency was evaluated; it was found that a simple difference in group means provided a better fit with the data, although some evidence of an object relations model also was found. Finally, Rorschach and MMPI-2 (Butcher, Dahlstrom, Graham, Tellegen, & Kaemmer, 1989) levels of general defensiveness and primary process manifestations in Rorschach content were investigated to assess whether participants were responding defensively to the testing and whether there were any differences in the nature of oral-dependent responses between the clinical groups.     

Is phonological information mapped onto semantic information in a one-to-one manner?

Spoken word recognition models have to explain the influence of mismatching information on lexical activation. The effect of mismatching information is usually addressed with cross-modal semantic priming experiments using priming effects as a measure of the degree of lexical activation. Pseudowords phonologically related to a semantic associate of the target, e.g., *domato-PAPRIKA, serve as primes. Mismatch effects at the word form level are supposed to percolate unaltered to the semantic level. We show that cross-modal semantic priming might underestimate activation at the word form level. Targets (e.g., PAPRIKA) were preceded by either phonologically related pseudoword primes (e.g., *baprika) or semantically related pseudoword primes (e.g., *domato). Different priming and RT patterns were obtained for the two priming relations.     

Memory for multidimensional source information

Source memory may comprise recollection of multiple features of the encoding episode. To analyze the simultaneous representation and retrieval of those multiple features, a multinomial memory model is presented that measures memory for crossed dimensions of source information. The first experiment investigated the validity of the new model. The model showed an excellent statistical fit to empirical data, and the parameters of multidimensional source memory were sensitive to manipulations of source similarity on distinct dimensions. The second experiment used the model to test the hypothesis that source memory for individual context attributes is stochastically related in the case of conscious recollection but independent in the case of familiarity-based recognition judgments. The prediction was supported by the introduction of a "remember"-"know" distinction in a multidimensional source memory test.
