Constructs, operational definition, and operational analysis

We argue that a certain picture of the relationship between language and the world informed Meehl’s outlook on how science worked. That picture authorized talk about constructs and has led to construct proliferation and other problems. Operational analysis offers an alternative view and suggests that a major shortcoming of soft psychology is its lack of disciplined limits on acceptable verbal behavior.     

The Role of Self-Focus,Task Difficulty,Task Self-Relevance,and Evaluation Anxiety in Reaction Time Performance

Self-focused attention has been found to facilitate task performance in some instances and inhibit it in others. Among chronically anxious individuals it appears to consistently hinder performance. Less is known about the impact of self-focus on the performance of normal individuals. The present study examines the role of task difficulty, task self-relevance, and presence of evaluation anxiety in the performance effects of self-focus among normal individuals. Participants performed a simple reaction time (RT) and a lexical decision task, in Experiments 1 and 2, respectively, with or without self-focus. Self-focus and evaluation anxiety resulted in faster responding in simple RT, but there was no significant effect of self-focus on performance in the more difficult lexical decision task. Participants' heart rate (HR) was monitored and indicated that orienting was associated with slower RT in both experiments, and less orienting was found during self-focus and evaluation conditions. Results are interpreted in light of several self-focus theories.     

Repetition deficits, list context, and word-class interactions in the RSVP of words in sentences.

We report a failure to find a repetition deficit in recall following the rapid serial visual presentation (RSVP) of words within sentences, using adjectives rather than nouns as the critical items. In a series of experiments that ruled out participant and procedural differences as the source of the failure, both word class and list context were found to moderate the repetition deficit, but grammatical necessity did not. The presence in the list of sentences in which the repeated adjectives were separated by more than three words (i.e., more than 400 ms in RSVP) not only eliminated the repetition deficit for the recall of those sentences but also for the recall of sentences in which the repeated adjectives were separated by three or fewer words (i.e., less than 400 ms in RSVP). However, although substantially reduced, a repetition deficit with noun-based materials was still found in this list context. Matching the adjective-based sentences with the noun-based sentences in sentence length and position of the critical items revealed that the moderating effect of word-class on the repetition deficit was mediated by the biases in sentence structure that using different word classes tend to induce.     

Learning to perceive object unity: a connectionist account

To explore questions of how human infants begin to perceive partly occluded objects, we devised two connectionist models of perceptual development. The models were endowed with an existing ability to detect several kinds of visual information that have been found important in infants’ and adults’ perception of object unity (motion, co‐motion, common motion, relatability, parallelism, texture and T‐junctions). They were then presented with stimuli consisting of either one or two objects and an occluding screen. The models’ task was to determine whether the object or objects were joined when such a percept was ambiguous, after specified amounts of training with events in which a subset of possible visual information was provided. The model that was trained in an enriched environment achieved superior levels of performance and was able to generalize veridical percepts to a wide range of novel stimuli. Implications for perceptual development in humans, current theories of development and origins of knowledge are discussed.     

Conceptualizing Transition: The Role of Metaphor in Describing the Experience of Change at Midlife

Five new or returning midlife university students were asked to provide metaphors describing their experience of midlife change, change indicated by their attending university at this point in their lives. Five resulting portraits (S. Lawrence-Lightfoot & J. H. Davis, 1997) were created, based on participant-invoked metaphors: personal rebellion against colonization, stage productions, collection and accumulation, journey home, and alchemy and metamorphosis. The portraits indicate that even from within widely divergent metaphoric conceptualizations, the respondents all find midlife to be an active, positive, and hopeful period of life. For them midlife is decidedly neither crisis nor dull plateau. Further, given the richness of the metaphor use, the study demonstrates the desirability of listening carefully to and moreover expressly soliciting metaphoric usage, in order to more fully understand people's inner realities. Finally, the portraits reveal that the participants' metaphoric conceptions are deeply imbedded in their lives, past and current, and as such identify life themes.     

Statistical analysis of timing errors.

Human rhythmic activities are variable. Cycle-to-cycle fluctuations form the behavioral observable. Traditional analysis focuses on statistical measures such as mean and variance. In this article we show that, by treating the fluctuations as a time series, one can apply techniques such as power spectra and rescaled range analysis to gain insight into the mechanisms underlying the remarkable abilities of humans to perform a variety of rhythmic movements, from maintaining memorized temporal patterns to anticipating and timing their movements to predictable sensory stimuli.     

Customer Service Orientation in Managerial and Non-Managerial Employees: An Exploratory Study

The customer service orientation of managerial and non-managerial employees from a large financial services organization were compared using the Customer Service Skills Inventory (CSSI). The results indicated that, in comparison to non-managerial employees, managers scored significantly higher on Pressure Tolerance, Independent Judgment, and Responsiveness, and significantly lower on Realistic Orientation.     

Developing Multicultural Counseling Competencies in Undergraduate Students

The authors assessed the impact of training undergraduates in multicultural counseling competencies. When compared with a control group of students in a psychology of personality course (n = 20), repeated measures analyses of variance confirmed that multicultural counseling trainees (n = 21) significantly increased levels of multicultural counseling awareness and knowledge. As expected, there were no significant changes in either multicultural counseling skills or empathic responding. Los autores evaluaron el impacto de educar a estudiantes universitarios sobre las competencias de consejería multicultural. Comparados con un grupo de control matriculado en un curso de psicología de la personalidad (n = 20), un análisis de variaeión de medidas repetidas confirmó que los niveles de consciencia y conocimiento de los estudiantes de consejería multicultural (n = 21) fueron significativamente aumentados. Como esperado, no se observaron cambios significativos en las habilidades de consejería multicultural ni en las reacciones empáticas.     

Life Stress and Major Depression

ABSTRACT— People have long believed that adversity and stress contribute to emotional problems in general and to depression in particular. A considerable body of research has supported this intuition, documenting a consistent association between major stressful life events and the onset of clinical depression. However, most individuals under stress do not become depressed, sometimes depression develops without prior stress, and distinguishing psychological distress from major depression can be diagnostically challenging. In varying forms and degrees, life stress may play multiple roles in relation to major depression. In this article, we outline the opportunities and obstacles associated with conceptualizing depression from a life-stress perspective and discuss the implications for future research.     

The Origin of Biases in Face Perception

ABSTRACT— Experience with certain types of faces during the first year of development defines which types of faces are more efficiently recognized later in life. In work described here, we found that infants who learned to recognize six monkey faces individually (i.e., each face was individually labeled) over a 3-month period maintained the ability to discriminate monkey faces. However, infants who learned these same six faces categorically (i.e., all faces were labeled "monkey") or were simply exposed to these faces (i.e., faces were not labeled) showed a decline in the ability to discriminate monkey faces. These results suggest that experience individuating faces from 6 to 9 months of age, via labeling, critically shapes the perceptual representation that is responsible for later recognition and discrimination of faces.
