The selective action of Cfunc control

According to relational frame theory Cfunc stimuli select which stimulus properties are transformed via derived stimulus relations. To date there has been no demonstration of the selective action of Cfunc control. We provide an analysis of the requirements for such a demonstration, and describe the results from four experiments employing a paradigm consistent with these requirements. We employed a paradigm based on virtual car races. The paradigm had two components: i) a sample racecar screen which showed the performance of a sample racecar, and used experimentally engineered symbols to communicate how the performance of each real racecar would compare with that of the sample racecar, and ii) a car race screen showing other racecars race. Two symbols were established as Crels for the relations of same and different, and two symbols were established as Cfuncs for the functional properties of speed and direction. The results from these experiments demonstrate Cfunc stimuli can select which functions transform via derived stimulus relations, a central component of relational frame theory. The study has implications for the study of relational responding in complex settings and for applied work aimed at refining repertoires of relational responding.

"Just stop thinking about it": effects of emotional disengagement on children's memory for educational material

Children regulate negative emotions in a variety of ways. Emotion education programs typically discourage emotional disengagement and encourage emotional engagement or "working through" negative emotions. The authors examined the effects of emotional disengagement and engagement on children's memory for educational material. Children averaging 7 or 10 years of age (N=200) watched either a sad or an emotionally neutral film and were then instructed to emotionally disengage, instructed to engage in problem solving concerning their emotion, or received no emotion regulation instructions. All children then watched and were asked to recall the details of an emotionally neutral educational film. Children instructed to disengage remembered the educational film better than children instructed to work through their feelings or children who received no emotion regulation instructions. Although past research has indicated that specific forms of emotional disengagement can impair memory for emotionally relevant events, the current findings suggest that disengagement is a useful short-term strategy for regulating mild negative emotion in educational settings.     

A latent class approach to fitting the weighted Euclidean model,clascal

A weighted Euclidean distance model for analyzing three-way proximity data is proposed that incorporates a latent class approach. In this latent class weighted Euclidean model, the contribution to the distance function between two stimuli is per dimension weighted identically by all subjects in the same latent class. This model removes the rotational invariance of the classical multidimensional scaling model retaining psychologically meaningful dimensions, and drastically reduces the number of parameters in the traditional INDSCAL model. The probability density function for the data of a subject is posited to be a finite mixture of spherical multivariate normal densities. The maximum likelihood function is optimized by means of an EM algorithm; a modified Fisher scoring method is used to update the parameters in the M-step. A model selection strategy is proposed and illustrated on both real and artificial data.The second author is supported as Bevoegdverklaard Navorser of the Belgian Nationaal Fonds voor Wetenschappelijk Onderzoek.     

The development of the SNARC effect: evidence for early verbal coding

In a recent study, Gevers and colleagues (2010, Journal of Experimental Psychology: General, Vol. 139, pp. 180-190) showed that the SNARC (spatial numerical association of response codes) effect in adults results not only from spatial coding of magnitude (e.g., mental number line hypothesis) but also from verbal coding. Because children are surrounded by rulers, number lines, and the like in the classroom, it is intuitively appealing to assume that they first use their mental number line to represent numbers and that only later in development a verbal recoding of magnitude information takes place. However, this hypothesis has never been tested. The goal of the current study was to define the developmental pattern of both accounts (spatial and verbal) in explaining the SNARC effect. To this end, 9- and 11-year-olds were tested in a magnitude comparison task. Surprisingly, clear and robust evidence for verbal coding of magnitude information was observed in both age groups. Our results imply that the ability to use verbal coding of magnitude information is robustly present early in formal schooling.     

Cognitive-behavioral treatment of high anger drivers

Relaxation and cognitive-relaxation interventions were compared to a no treatment control in the treatment of high anger drivers. The cognitive portion of the cognitive-relaxation condition adapted the style of Beck's cognitive therapy, particularly use of Socratic questions and behavioral experiments and tryouts, to driving anger reduction. Both interventions lowered indices of driving anger and hostile and aggressive forms of expressing driving anger and increased adaptive/constructive ways of expressing driving anger. The cognitive-relaxation intervention also lowered the frequency of risky behavior. Both interventions lowered trait anger as well. Limitations and implications for treatment and research were discussed.     

Narcissism and body image

This research examined the relationship between narcissism, as measured by the Narcissistic Personality Inventory (NPI; Raskin & Hall, 1979), and body image, as measured by the Body-Self Relations Questionnaire ( Winstead & Cash, 1984), in a nonclinical sample of college students. Also examined were narcissism's relationships to masculinity, femininity, and self-esteem. Results indicated that more narcissistic individuals had more favorable body images and were higher in masculinity and self-esteem. No gender differences were observed in either the levels of narcissism or its body image correlates. Overall, the findings suggest that the NPI measures “adjusted” narcissism rather than the “maladaptive” narcissism emphasized in theoretical and clinical accounts of the construct.     

Frames of reference and cooperative social decision-making

Cooperative decision-making was studied as a function of the decision-makers' own, and the interdependent other party's gain or loss frame. As expected, results showed that (a) an own gain frame produced less cognitive activity than an own loss frame and (b) other's loss frame caused more cooperation than other's gain frame, but only in case of an own gain frame.     

A latent class unfolding model for analyzing single stimulus preference ratings

A multidimensional unfolding model is developed that assumes that the subjects can be clustered into a small number of homogeneous groups or classes. The subjects that belong to the same group are represented by a single ideal point. Since it is not known in advance to which group of class a subject belongs, a mixture distribution model is formulated that can be considered as a latent class model for continuous single stimulus preference ratings. A GEM algorithm is described for estimating the parameters in the model. The M-step of the algorithm is based on a majorization procedure for updating the estimates of the spatial model parameters. A strategy for selecting the appropriate number of classes and the appropriate number of dimensions is proposed and fully illustrated on some artificial data. The latent class unfolding model is applied to political science data concerning party preferences from members of the Dutch Parliament. Finally, some possible extensions of the model are discussed.The first author is supported as Bevoegdverklaard Navorser of the Belgian Nationaal Fonds voor Wetenschappelijk Onderzoek.
