Equating the brightness of brief visual stimuli of unequal durations

The brightness of brief displays whose durations do not exceed a critical period of integration is known to covary with stimulus duration (Bloch’s law). There are cases in which the interdependence of duration and brightness introduces an unwanted confounding that must be avoided. Three methods for equating the brightness of brief stimuli displayed under computer control are described and evaluated, and an example of the outcome obtained with the most efficient procedure is reported.     

Self-reported assessment practices of school psychologists: Implications for training and practice

This study reports the results of an investigation of the assessment views and practices of school psychologists in the United States. Results of the investigation indicated that respondents are predominantly behavioral and cognitive behavioral in orientation; spend most of their professional time in the public schools; and engage in a great deal of assessment. Behavioral assessment and projective testing occupies the greatest amount of their social-emotional assessment time. Behavioral interviewing is the most used behavioral technique, followed by behavioral observation, which is reportedly used by approximately one third of the respondents with from 41% to 100% of clients. Although most of the respondents report a preference for continuing to do approximately the same amount of the various social-emotional assessment activities as they are presently doing, very high percentages of respondents indicate that their use of behavioral assessment strategies would increase with development of published instrumentation, normative standards, and standardized out-of-setting behavioral procedures.     

Performance differences following exposure to predictable and unpredictable noncontingent outcomes in high and low achievers

Two experiments are described in which subjects rated as high or low in achievement motivation were exposed to uncontrollable outcomes on a cognitive task. Effects on subsequent performance on a different cognitive task were shown to depend on level of achievement motivation, on whether the uncontrollable outcomes were predictable or unpredictable, and on whether the uncontrollable outcomes were positive or negative. These findings have important theoretical implications which are discussed.     

Successful psychotherapy

This paper develops an existential explanation for the position that different psychotherapeutic modalities enjoy comparable success rates. The explanation provides necessary and sufficient conditions for a successful outcome, related to the actualization level of both client and therapist, and is shown to imply equal theoretical probability of success across modalities.     

Food anticipation and lever-directed activities in rats

Three experiments are described which elaborate some of the conditions under which rats will contact and manipulate a periodically presented retractable lever. Experiment 1 demonstrated that (i) initial manipulative oral and manual contact with the lever was facilitated if the rat had previous experience of food delivery in the experimental chamber; (ii) persistence in contacting the lever on successive presentations was a function of whether food continued to be presented in the experimental environment; and (iii) food satiation significantly reduced the tendency of the rat to contact the lever even though an expectancy of food had previously been established under conditions of food deprivation. Experiment 2 suggested that the tendency to approach and contact the lever was in part a function of the local moment-to-moment conditional probability of food delivery. Experiment 3 found that the probability of contacting the lever was higher during presentation of an auditory CS signaling a high rate of food delivery than during stimuli signaling no food at all. These results are interpreted as suggesting that the food-signaling aspects of an appetitive CS and that CS's ability to generate signal-directed behaviors are experimentall separable properties.     

When left hands touch: shadow vows and Jung’s quaternity

Is there a connection between the exchange of vows and the fighting and suffering of couples that are unique to the institution of marriage? This essay introduces the concept of Shadow Vows, the unacknowledged assumptions, agreements, and obligations each partner brings to the relationship, which the authors believe are often responsible for longstanding marital discord and strife. The authors ground the existence of shadow vows in Jung’s quaternity, alchemy, typology, archetypal theory, and depth approaches to couple therapy. The essay concludes with a list of themes indicative of shadow vow enactments in clinical work with couples.     

Are curmudgeon personality scales resistant to response distortion?

Curmudgeon personality, which is assessed by having participants evaluate a heterogeneous set of attitude objects, provides an applied value beyond that of more established personality traits. Recent research, for instance, suggests that curmudgeon personality is distinct from the Five Factor Model personality traits and that it predicts unique variance in important criteria, such as job attitudes and well-being. In the current paper we contribute to this literature by testing an explanation of how curmudgeon personality is distinct from other traits—their potential resistance to response distortion. We estimated response distortion for scales of curmudgeon personality and FFM traits across two quasi-experimental studies. As expected, the score shifts between nonapplicant and applicant conditions were smaller for scales of curmudgeon personality compared to scales of emotional stability and conscientiousness. We argue that curmudgeon personality scales may be more resistant to response distortion than are measures of other traits because curmudgeon personality items are semi-implicit and lack an obvious desirable response. The resistance to response distortion should serve as a call to future researchers to test the criterion validity of curmudgeon personality in regard to performance criteria.
