Relationships among Multiple Task Asymmetries: II. A Large-Sample Factor Analysis

Samples from published and unpublished factor analytic studies of multiple task asymmetry are combined to produce a large-sample factor analysis of 10 measures, prescreened for significant asymmetry and acceptable reliability, from 9 lateralized tasks. A full correlational matrix is presented, with task pairings having sample sizes ranging from 103 to 479 (meanN= 290). Both significant positive and significant negative correlations between measures are found. Extraction and oblique rotation of five factors fails to reveal any evidence of a global relationship among lateral difference measures, and principal-components analysis likewise fails to reveal a component to which all measures correlate positively. However, evidence for local structure is found. Results are interpreted in terms of dissociable hemispheric processes, and consideration is given of the possible existence of modality-specific characteristic perceptual asymmetry and of single versus multiple determination of lateral differences.     

Visual and phonetic codes and the process of generation in letter matching

Physically identical letter pairs are matched more quickly than are nominally identical or nonidentical pairs, which is an effect usually interpreted as resulting from the use of a visual memory code versus a phonetic or name code. However, prior manipulations of phonetic confusion and visual-field lateralization have provided little evidence consistent with this notion. Here, three reaction time experiments suggest through converging confusion and visual-field manipulations that a phonetic code is not used in either simultaneous or successive letter matching. Two additional experiments yield confusion evidence consistent with a rapid visual generation process underlying nominally identical and nonidentical matches, emphasizing the role of visual memory processes in all of the commonly used same-different letter-matching tasks. Implications for coding and hemispheric theories are discussed.     

Fast visual generation: its nature and chronometrics.

The fast-generation model for the matching of mixed-case letter pairs (e.g., Aa, Ab) states that one or both members of a pair activate visual representations in memory of the opposite case, supporting "same" or "different" responses through crossmatching to representations of the pair members themselves. Here the reaction time and error results of three experiments using simultaneous matches support a specific variant of the model in which generation proceeds from the uppercase letter. Furthermore, a manipulation of stimulus onset asynchrony in a fourth experiment using near-simultaneous matches indicates that fast generation produces a visual representation that occurs within 67 msec of initiation and that decays within 200 msec. A fifth experiment contrasts simultaneous and successive matches and in the case of successive matches finds evidence in support of a regeneration process acting after an initial decay. Models of mixed-case matching that are based on the phonetic representation of letter names, or on abstract-letter identities, completely fail to account for the results. Fast generation is distinguishable from slow generation in that it shows fast (vs. slow) dynamics, rapid decay (vs. maintainability), no imagery (vs. imagery), and (probably) automatic (vs. controlled) processing.     

False pretense and deviant exploitation: Fortunetelling as a con

This paper presents a dramaturgical analysis of the backstage manipulations carried out by practitioners of the deviant occupation known as fortunetelling. It is generally believed that con games require a dishonest victim, although many practitioners manipulate their impressions with clients who are seeking a service rather than a profit. The group of fortunetellers included in this study are nonbelievers and hence fundamentally misrepresent themselves to their clients. Drawing upon depth interviews with 21 non‐Gypsy fortunetellers, including two key informants, six backstage routines are analyzed. Each routine in the fortuneteller's performance presents the client with a frontstage definition of the activity designed to sell more and more “psychic services.” The implications of the dramaturgical analysis of con games are discussed.     

The Impact of Realistic Job Previews and Perceptions of Training on Sales Force Performance and Continuance Commitment: A Longitudinal Test

This study uses a an adaptation of the Dubinsky et al. (1986) socialization framework to test the impact of realistic job previews and perceptions of training on sales force performance and continuance commitment. Seven hundred sixty-two insurance salespeople in 54 companies were surveyed four times over a two-year period. The findings indicate that the socialization of new recruits should be focused on two parallel tracks: factors that primarily influence performance and those that primarily influence turnover.
