Memory-basedsame-different conceptualization by pigeons

We first trained pigeons to peck one button (same) after the successive presentation of 16 identical pictures and to peck a second button (different) after the successive presentation of 16 nonidentical pictures. Later, we tested the birds with other lists ofsame anddifferent items composed of completely novel pictures. Accuracy to the testing lists reliably exceeded chance levels, thus demonstratingsame-different conceptualization by pigeons under conditions that, for the first time, (1) eliminated purely perceptual mechanisms of discrimination learning and transfer and (2) required memory-based processing of the experimental stimuli.     

Shyness: conceptualization and measurement

The concept of shyness and its measurement were investigated in a series of studies (total N = 1,687). Data collection and analysis proceeded in three phases: the revision and continued development of a measure of shyness, the Social Reticence Scale; a psychometric comparison among five measures of shyness; and an examination of the factor structure underlying the construct of shyness. Phase 1 assessed the reliability and validity of the Social Reticence Scale, including ratings of videotaped monologues and ratings by significant others. Phase 2 compared the five shyness measures with one another on indices of internal consistency and with other relevant measures of emotionality, personality, relationships, and behavior. Items from the five shyness measures were combined in a factor analysis in Phase 3, and the resulting factors were correlated with the self-report and rating data obtained in Phase 2. Overall, the results from these studies confirmed that the shyness measures were valid, reliable, and empirically distinct from measures of related constructs. Behavioral validity was observed for several of the shyness scales. Additional analyses suggested that three interpretable factors underlie responses to the shyness scales but provided little support for drawing conceptual distinctions among types of shyness. Discussion focuses on the implications of these data for the measurement and conceptualization of shyness.     

Pavlov's conceptualization of learning.

Introductory texts in psychology create the misleading impression that I. P. Pavlov was concerned solely with conditioned reflexes. In fact, influenced by Woodworth's Contemporary Schools of Psychology (1931), Pavlov also became interested in learning. Pavlov proposed a two-factor learning theory according to which all learning was based on association, but conditioning and trial and error learning had specific functions. According to Pavlov, conditioned reflexes were temporary and unstable and therefore more flexible in the interaction of higher organisms with the changing environment. Trial and error learning provided knowledge and was relatively more stable. Scientific discovery was based on facts obtained by trial and error; valid relations were reinforced by experimental results, whereas incorrect relationships were extinguished. Some suggestions are made that would allow authors of introductory texts to describe more informatively the contributions of Pavlov to modern psychology.     

A spherical conceptualization of personality traits

This research utilizes the geometric structure of the two‐dimensional Interpersonal Circumplex (IPC), and adds the Five‐Factor Model (FFM) dimension of conscientiousness to create a three‐dimensional spherical model of personality; the interpersonal sphere (IPS). A sample of 250 participants was initially used to select items that conformed to the geometric locations of 26 different characteristics on the IPS. A separate sample of 251 participants confirmed the geometric structure of these characteristic measures using randomization tests. To demonstrate an application of this three‐dimensional model, the IPS was employed as a geometric taxonomy to map various personality constructs. The combined sample of 501 participants was used to cartographically locate 164 scales from the NEO Personality Inventory, (NEO‐PI‐R), the 16 Personality Factor Questionnaire (16PF), the California Psychological Inventory (CPI), the Hogan Personality Inventory (HPI), the Temperament and Character Inventory (TCI), the Multidimensional Personality Questionnaire (MPQ), and the Jackson Personality Inventory (JPI‐R) onto the IPS. The spherical conception of traits provided by the three‐dimensional IPS is discussed as both an extension of the FFM and the two‐dimensional IPC. Copyright © 2006 John Wiley & Sons, Ltd.     

Childhood amnesia: a conceptualization in cognitive-psychological terms

Childhood amnesia is defined operationally as the forgetting of early life events to a significantly greater degree than is accounted for by "normal" forgetting, which is an increasing recall decrement as time since occurrence increases. Three cognitive processes and their developmental changes are discussed which, when considered with psychodynamic factors, may broaden the understanding of childhood amnesia. It is argued that psychoanalytic theory and technique can benefit from the research and methods of cognitive psychology.     

A conceptualization of firesetting in children and adolescents

Juvenile firesetting has been studied from different perspectives and by multiple disciplines. Although evidence has begun to emerge regarding the antecedents and correlates of firesetting as well as characteristics of firesetters and their families, the findings and their conceptual bases remain somewhat diffuse. This paper integrates major findings reported in the juvenile firesetting literature and provides a tentative model of firesetting risk based on the current evidence. The model highlights several factors within three major domains: learning experiences and cues, personal repertoires, and parent and family influences and stressors. Implications of the model for early identification, diagnosis, and treatment of firesetters are discussed.Completion of this paper was facilitated by grants (MH35408 and MH00353) from the National Institute of Mental Health.     

Identification and conceptualization of procedural chunks in chess

When it comes to cognitive architecture and human information processing, chunks are one of the best known and most recognized constructs. Nevertheless, the nature of chunks is still very elusive, especially when it comes to chunks in procedural knowledge. This study deals with basic features of procedural information processing and examines the manifestation of chunks in procedural knowledge. The participants' task was to reconstruct sequences of chess moves. Chess was chosen as an experimental domain, because of its complexity, well-defined rules and standardized measure of chess player strength. From the results we conclude that short-term memory capacity is determined by the combination of the size and amount of procedural chunks recalled to the short-term memory. We have shown that on average, participants with more specialized knowledge operated faster and with larger chunks of procedural information than participants with less specialized knowledge. We have shown that in procedural information processing, the level of expertise and the sorting order of the retrieved information are important factors that influence the amount of procedural chunks retained in the short-term memory. Therefore, the capacity of short-term memory in complex situations cannot be expressed as a simple concept.     

Chronic pain conceptualization and religious interpretation

The pastoral counselor often interviews patients suffering from chronic pain. Many of them express religious notions about their suffering. This article examines some traditional concepts of pain and types of religious interpretations, and proposes appropiate roles for the pastoral counselor.     

Apparatus conceptualization for psychopathological research inmonkeys

Investigation of psychopathology in monkeys requires analysis of multiple variables mediating specific behaviors. Assessment of both the relative contribution of each variable and the interactions among them is facilitated by the use of apparatuses whose designs permit separate or simultaneous manipulation of several variables. Three such devices, the pit, the tunnel of terror, and the standard living-experimental cage, each specifically constructed for the production of depression or despair in monkeys, are described.     

The conceptualization and measurement of attributions

Substantial knowledge has been gained about the information processing that underlies attribution, biases and errors in the perception of causation and responsibility, and several types of consequences of attribution. We have far less systematic information about the adequacy of those measures typically employed to elicit attributions. Several issues in the conceptualization and measurement of attributions are explored in this paper, drawing on confirmatory factor analyses of attributions in two related samples. Central issues include: (1) the validity and reliability of several types of attributional measures; (2) the relationship between dispositional and situational attributions; and (3) the specificity and meaning of particular attributional categories.     

The measurement and conceptualization of curiosity

In this study, the authors tried various methods to measure and conceptualize curiosity. A sample of 369 education students (103 men, 266 women) who were attending universities on the East Coast of the United States completed 5 paper-and-pencil curiosity measures in 1 of their classes. Using confirmatory factor analysis, the authors found that the data best fit a 3-factor curiosity model consisting of cognitive curiosity, physical thrill seeking, and social thrill seeking. These findings supported the development of new instruments that specifically measured those 3 curiosity types, new empirical research predicting meaningful curiosity-related outcomes, and subsequent theory building concerning how and why curiosity is a fundamental part of optimal human functioning.     

A conceptualization and measure of argumentativeness

A conceptualization and measure of argumentativeness is reported. Argumentativeness was conceptualized as a trait Which is composed of the tendency to approach arguments and the tendency to avoid arguments. A 20-item, self-report scale was developed in a series of three factor analytic studies. The internal consistency and test-retest reliabilities of the scale were high. A series of additional studies yielded considerable evidence as to the validity of the scale. The conceptualization of argumentativeness accounts for state as well as trait components. The state components consisted of the individual's perceptions of the probability and importance of success and failure in a particular argumentative situation. A hypothesis was supported which posited response to a particular argument would be predicted better by trait and state components together than by the trait component alone.
