Father-daughter incest families: A theoretical perspective from balance theory and GST

This paper focuses on a theoretical explanation of how marriages adjust and remain intact in father/daughter incest families. It uses concepts of Balance Theory and General Systems Theory to outline a vascillating balance that occurs between fathers-mother-daughters in incest families. Three groups of Incest, Oppositional, and Nonclinical family units were studied using the Structural Analysis of Social Behavior (SASB) circumplex model. The study found support for the use of Balance Theory and the systems principle of homeostasis as a way to understand the interactional dynamics in incest families. Therapeutic interventions are suggested.Curtis A. Levang has spent more than 10 years working with adult offenders at Hennepin County Adult Corrections in Plymouth, Minnesota.

Subvocalization rate versus other predictors of the memory span

Two experiments were performed to determine how accurately the immediate memory span may be predicted from the subject's subvocalization rate, as compared with other subject and stimulus variables. In the first, span and free-recall measures were obtained for 24 subjects, each tested with four types of spoken material (nonsense syllables, random words, fourth-order approximations to English, and normal prose). Silent subvocalization rate, whispered subvocalization rate, speaking rate, and silent reading rate were also measured for each subject. The span (3.9-14 items) showed the highest zero-order correlation with silent subvocalization rate: r = .80. Multiple regression analysis confirmed this as the span's best predictor, partial r = .31. Similar results were found for free-recall scores. In Exp. 2 the digit span was correlated against measures of age, intelligence, subvocalization rate, perceptual speed, and memory search rate, for 40 subjects aged 7 to 17 yr. The best zero-order predictor was age (.62), followed by subvocalization rate (.57) and intelligence (.39). Multiple regression analysis indicated that the span was best predicted by age, partial r = .37, and subvocalization rate, partial r = .29. The span appears more closely related to subjects' internal speech rate than to other cognitive functions.     

Positive and Negative Androgyny and Their Relationship with Psychological Health and Well-Being

A new method of scoring the Extended Personal Attributes Questionnaire (EPAQ) was used to assess the constructs of positive and negative androgyny. The EPAQ was administered to 196 adult women and men; their responses were categorized into a differentiated androgyny. Significant differences were obtained between positive and negative androgynous people as well as between positive and negative feminine and positive and negative masculine people on a set of measures of psychological health and well-being. These findings support the validity and utility of differentiating androgyny into positive and negative categories of gender role identity.     

Motion perception over long interstimulus intervais

Recent studies using moving arrays of textured micropatterns have suggested that motion percep-tion can be supported by two mechanisms, one quasilinear and sensitive to the motion of luminance-defined local texture, the other nonlinear and coding motion of contrast-defined envelopes of texture (Baker & Hess, 1998; Boulton & Baker, 1993b). Here we used similar patterns to study motion percep-tion under conditions previously shown to isolate the nonlinear mechanism (low micropattern densi-ties and positive interstimulus intervals [ISIs]). We measured direction discrimination for two-flash ap-parent motion over a much larger range of ISIs, and susceptibility to masking by incoherently moving “distractor” micropatterns. The results suggest that two nonlinear mechanisms can support motion perception under these conditions. One operates only for relatively short ISIs (less than c. 100 msec), is sensitive to small spatial displacements, and is relatively insensitive to distractor masking. The other operates over much longer ISIs, is insensitive to small spatial displacements, and is highly disrupted by distractor masking. These results are in line with previous studies suggesting that three mechanisms support motion perception.     

Judgments About Sexism: A Policy Capturing Approach

Different definitions of sexism have been usedby different experimenters and little attention has beengiven to the possibility that participants' definitionsof sexism might vary across individuals and across situations, just as the definitions ofinvestigators vary. Judgments about sexism areinextricably based on individual perceptions, values,and beliefs. It would seem reasonable, therefore toexamine individual conceptions of what constitutessexism. A total of 95 primarily middle-class Caucasianparticipants (68 females, 27 males) participated inthree studies investigating what information people use in deciding whether or not a male actor issexist. Six specific categories of information (or cues)were examined: (1) comments (or lack thereof) by theactor on a female target's physical appearance, (2) unwanted or inappropriate physical contact(or lack thereof), (3) assumptions (or lack thereof)about the target's work, personality, etc., based on hergender, (4) the target being interrupted (or not) by the actor, (5) an apparent powerdifferential (or lack thereof) between the actor and thetarget, and (6) assumptions by the actor aboutappropriate gender role behaviors. A policy capturingmethodology was employed in which three different sets ofscenarios, each describing a number of interactions(called profiles) between a target and an actor, werepresented to male and female participants who rated the degree of sexism exhibited by the actor ineach scenario. Policy capturing represents anideographic approach to research in which the primaryfocus is on establishing statistical parameter estimates that describe each individual's behavior in avariety of environmental situations. Only when that isaccomplished does the researcher examine the possiblenomothetic aggregations across participants. Thus many fewer participants are required than intraditional nomothetic approaches. Each profile set useda different subset of the cues which contained eithersubtle (Study 1), overt (Study 2), or very overt (Study 3)levels of the cues. Multipleregression analysis revealed that when relatively overtacts of sexism were described, most participants hadreliable policies; that is, their judgments werepredictable from the cues. However, when relatively subtleacts of sexism were described, most participants did nothave reliable policies; that is, their judgments werenot very predictable from the cues. There were large individual differences in howparticipants weighted the importance of various cues,especially with subtle cue levels, and in participants'mean sexism ratings.     

Categorical processing of visual stimuli in relation to geometrical,graphemic, or lexical context

Summary Categorical perception was first demonstrated in studies of speech sounds (Liberman, Harris, Hoffman, & Griffith, 1957). The present work employed visual stimuli to explore categorical responding in relation to the context in which the stimuli were embedded. The target stimulus was a vertical line whose length was varied from 20 to 31 min (approximately) in steps of 1.2 min. Experiment 1 examined the effect of a geometrical context on the subjects' ability to discriminate between pairs of lines. The context improved performance, but produced no evidence of categorical responding. In Experiment 2 a graphemic context depressed performance, but failed to show clear evidence of categorization. By contrast, strong evidence of categorical responding was obtained in Experiment 3, in which the graphemes used in Experiment 2 were embedded in meaningful words. From this pattern of results it is argued that categorical responding is reflective not of relatively peripheral perceptual activity, but of higher-order decision processes.
