Contextual dependencies in motor skills

The development of contextual dependencies during motor skill acquisition was examined. Environmental context was varied along intentional and incidental dimensions. Intentional stimuli were defined as essential for achieving skilled performance, whereas incidental stimuli were defined as those that have the potential to become associated with specific tasks due to their selective presence in the learning environment. Experiment 1 demonstrated the occurrence of contextual dependencies for the learning of four-key typing sequences. Contextual dependencies were diminished in Experiment 2 when the number of keys used in the sequences was reduced. In Experiment 3, a retention condition was incorporated, in which both the intentional and the incidental stimuli were not available; this confirmed that task difficulty mediated the development of contextual dependencies. These findings are discussed with respect to the incorporation of environmental contextual stimuli with memorial representations of movement information.     

Task performance and magnitude of goal valence

J. W. Brehm and his associates (J. W. Brehm, R. A. Wright, S. Solomon, L. Silka, & J. Greenberg, 1983, Journal of Experimental Social Psychology, 19, 21–48) recently argued that the magnitude of goal valence (the attractiveness or unattractiveness of a potential outcome) varies directly with motivational arousal level. Motivational arousal, in turn, is thought to be a function of the perceived difficulty of goal attainment. This formulation was tested in the present study by examining the relationship between goal attractiveness ratings and performance on an anagram task. According to the Yerkes-Dodson law (R. M. Yerkes & J. D. Dodson, 1908, Journal of Comparative Neurological Psychology, 18, 459–482), the relationship between motivational arousal and performance should be curvilinear; optimal performance is usually observed for moderate levels of motivation relative to either low or very high motivation levels. Consistent with the Brehm et al. hypothesis, optimum performance in the present study was observed for subjects who reported moderate levels of goal attractiveness relative to subjects who reported either low or high levels of goal attractiveness. Anticipatory ratings of the difficulty of the anagrams were also congruent with the Brehm et al. model. These findings converge with data from other studies supporting the utility of goal attractiveness as an index of motivational arousal and provide an additional dimension of support for the model proposed by Brehm et al.     

The essential process in a family of measurement models

Five members of the Rasch family of latent trait models which have appeared more or less independently in the literature are brought together and identified as one model. In addition to sharing the distinguishing characteristic of the dichotomous Rasch model—separable person and item parameters and hence sufficient statistics—all five models share a common algebraic form and have as their basic element the fundamental process defined by Rasch's simple logistic expression. In these models, the sufficient statistics for person and item parameters are counts of events constructed to be indicative of the variable being measured, and the measures they enable are ‘fundamental’.     

The effect of social cues on the eating behavior of obese and normal subjects1

Schachter's externality hypothesis suggests that overweight individuals are more likely to be induced to eat by salient external cues than normal weight individuals. While a range of studies have demonstrated the plausibility of this hypothesis in the case of sensory stimuli (e.g., taste cues), there is little evidence that the hypothesis applies to social stimuli. The current study examines this latter proposition by exposing male and female, overweight and normal weight subjects to a same-sex or opposite-sex peer model. Under the guise of engaging in a taste experiment, the subjects were either exposed to a model who tasted experiment, the subjects were either exposed to a model who tasted no crackers (no eat), one cracker (low eat), or twenty crackers (high eat). In addition, control model-absent conditions were also run for purposes of establishing baseline eating rates. If the externality hypotheses were to prevail in social domains, one would expect overweight subjects to be more prone to model the cracker-eating behavior of the peer than normal weight individuals. However, the findings indicate that all subject groups regardless of weight evidence a rather clear modeling effect and all subjects evidence social inhibition effects on their eating behavior as well. Several intriguing interactions among subject sex, model sex, subject weight, and social condition were also found. The discussion explores the relevance of an externality model of overweight eating in social domains, and focuses upon the interesting and somewhat distinct pattern of socially mediated eating exhibited by overweight females.     

A simple behavioral treatment program for psychogenic encopresis

A treatment program based on behavioral psychological principles which can be explained to parents in one session and supervised by letters and phone calls each week was found to be highly effective in completely eliminating the problem of psychogenic encopresis. A controlled study and extensive clinical use have indicated 100% effectiveness for the program when carefully adhered to.     

Training in family therapy: perceptual, conceptual and executive skills.

This paper presents a comprehensive and detailed outline of family therapy skills to aid in providing a more precise focus in the training of clinicians in family therapy. The skills are based on an integrated treatment model within a systems framework. Four major functions performed by a family therapist are separated and are further differentiated into general therapeutic competencies. Specific perceptual, conceptual, and executive skills are described in the form of instructional objectives and are listed under each competency. Occasional clarifying notes or examples are cited along with particular skills. Clinicians and trainees should find this outline a useful guide in skill development.     

Effects of maternal themes upon death imagery

Two samples (n = 47, n = 45) of women were studied to determine the impact of maternal messages upon death imagery as measured by the Holtzmann Inkblots. In both samples a maternal symbiotic message significantly decreased death imagery. A maternal monosymbiotic message resulted in decreased death imagery in only one sample. Control messages produced no changes in death imagery. The findings are congruent with theories that link death anxiety with concern about separation from parental figures.     

Testing the multiplicative hypothesis of intensifiers

The way in which intensifiers affect the meaning of the phrases to which they are applied is investigated. Previous research demonstrates that they often have little impact in between-subject designs. Here we present research which demonstrates that their effects in within-subject designs do not conform to the multiplicative hypothesis. Both the psychological mechanisms employed and the implications for survey methodologists are discussed.     

Teaching the History of Counseling: Training the Next Generation

The authors describe a teaching activity using a poster-session format to teach first-year counseling psychology doctoral students the history of counseling. Evaluative data suggest that the format was an effective and powerful tool to teach beginning counseling psychology students the history of the profession. The implications of the evaluative feedback are discussed in terms of teaching and preparing the next generation of counselors.
