Using Relative Motion Plots to Measure Changes in Intra-Limb and Inter-Limb Coordination

Methods for determining the degree of similarity between relative motion plots are examined and computational methods outlined. Hypothetical examples are provided to simply illustrate the function of selected indices of pattern shape, size, and orientation. Methods of using a composite of these measures to assess asymmetry, abnormality, or refinements in motor function are discussed. Statistical procedures for determining the reliability of assessments of change in relative motions are presented. A modification to Freeman’s (1961) pattern-recognition method is suggested as a more parsimonious application to angle-angle data derived in human movement research.     

A New Experimental Approach to the Relationship Between Color-Shading and Suicide Attempts

A new experimental approach was devised to increase responses to color and shading, thereby facilitating study of the previously demonstrated relationship between Rorschach Test color-shading responses and suicide attempts. The present study demonstrates that of 17 matched pairs of hospitalized psychiatric patients, those who had attempted suicide give significantly more shading responses to chromatic cards than those who had no history of suicide attempts. These results suggest that the technique may be useful in further studies of affect.     

Effect of Social Desirability and Self-Concept Scores on the Measurement of Adjustment

The study represented an attempt to assess the “true” nature of the relationships among measures of social desirability, self-concept, and level of adjustment. Positive linear relationships, of low to moderate magnitudes, were found for all three variables. These data do not support the traditional hypotheses that self-concept tests are saturated with social desirability, that social desirability is the primary component in the measurement of adjustment, nor that self-attitudes are the major variable in adjustment. An alternative system is presented for describing the psychometric relationships among these variables, with implications for viewing non-test correlates.     

Studies of Family Relations Test Patterns: 1. Test Inhibition

An empirical investigation of Bene and Anthony's (1957) “tenderness vs. toughness” hypothesis of inhibition in boys was conducted. Examination of the Family Relations Test (FRT) protocols of 217 boys (age range, 7 years 2 months to 12 years 10 months; IQ range, 80 to 132) referred to Calgary School Board psychologists, showed Bene and Anthony's hypothesis to be valid in this sample. Evidence is given to suggest that each of the eight scoring categories should be viewed separately for inhibition trends and not summed over any of the three dimensions, intensity, direction, and valence. The relation of FRT Inhibition to reason for referral was examined but only in the eight-year-old group was any significant relationship found.     

The Assessment of Subjective Well-Being and Its Relationship to the Stress Process

Research into relationships between stressors and adaptational outcomes has often represented well-being as the relative tack of pathological signs, However, such assessments do not discriminate between not being ill and experiencing degrees of subjective well-being (i.e., from feeling "OK" to feeling "Great"). This article suggests that subjective well-being be more narrowly defined to refer strictly to positive indicators of health status. In this study, psychometric properties of a new instrument, the Well-Being Scale-36, were examined. Relationships between subjective well-being and components of the stress process were explored. The results indicated that well-being and various forms of pathology should be conceptualized as distinct but related entities.     

Brain potentials during language production in children and adults: An ERP study of the English past tense

The current study examines the neural correlates of 8-to-12-year-old children and adults producing inflected word forms, specifically regular vs. irregular past-tense forms in English, using a silent production paradigm. ERPs were time-locked to a visual cue for silent production of either a regular or irregular past-tense form or a 3rd person singular present tense form of a given verb (e.g., walked/sang vs. walks/sings). Subsequently, another visual stimulus cued participants for an overt vocalization of their response. ERP results for the adult group revealed a negativity 300–450 ms after the silent-production cue for regular compared to irregular past-tense forms. There was no difference in the present form condition. Children’s brain potentials revealed developmental changes, with the older children demonstrating more adult-like ERP responses than the younger ones. We interpret the observed ERP responses as reflecting combinatorial processing involved in regular (but not irregular) past-tense formation.     

Clinical Judgment and Clinical Significance in Psychotherapy Practice

The use of outcome measurement in psychotherapy practice is briefly discussed, as is Jacobson and Truax’s (J Consult Clin Psychol 59:12–19, 1991) conception of clinically significant change. A more flexible and user friendly application of clinically significant change compatible with clinical judgment is proposed for psychotherapy practice. Examples are given and a free Windows program is described for computing RC and estimating the probability associated with it.     

Concurrent reinforcement schedules for problem behavior and appropriate behavior: experimental applications of the matching law

This study evaluated how children who exhibited functionally equivalent problem and appropriate behavior allocate responding to experimentally arranged reinforcer rates. Relative reinforcer rates were arranged on concurrent variable-interval schedules and effects on relative response rates were interpreted using the generalized matching equation. Results showed that relative rates of responding approximated relative rates of reinforcement. Finally, interventions for problem behavior were evaluated and differential reinforcement of alternative behavior and extinction procedures were implemented to increase appropriate behavior and decrease problem behavior. Practical considerations for the application of the generalized matching equation specific to severe problem behavior are discussed, including difficulties associated with defining a reinforced response, and obtaining steady state responding in clinical settings.     

I think I like you: Spontaneous and deliberate evaluations of potential romantic partners in an online dating context

The present research examined processes of impression formation within an online dating context. Across two studies, female participants formed impressions of a potential partner based on an online dating profile containing information about the target's facial attractiveness and self‐described ambition. Afterwards, deliberate evaluations of the target were assessed with a self‐report measure and spontaneous evaluations were measured with an affective priming task. The results showed that deliberate evaluations varied as a function of both self‐described ambition and facial attractiveness. In contrast, spontaneous evaluations varied only as a function of facial attractiveness. Experiment 2 further showed that these effects were independent of the order in which the two types of information had been encoded. The results are discussed in terms of associative and propositional processes, and the conditions under which these processes can lead to conflicting evaluations of the same potential romantic partner.
