Pregnancy: A social stigma?

Experimental evidence is presented which explores the social stimulus value of pregnancy. It was found that, for men especially, the pregnant woman elicits avoidance and staring and that these responses occur primarily because pregnancy is a novel visual stimulus. For women, avoidance seems to be tied less to the stimulus aspects of the pregnant woman than to role expectations about her behavior. The pregnant woman is expected to be passive, but is simultaneously rejected for being so. It is argued that this constellation of responses may produce discomfort and withdrawal in the pregnant woman herself, since avoidance and staring are easily interpreted as negative reactions. How these reactions fit into the cultural response to pregnancy is discussed.     

Dimensional interactions in vibrotactile information processing

The effect of irrelevant dimensional variation on the processing of vibrotactile stimuli was measured. Six observers performed a speeded classification task with stimuli varying along the dimensions of pitch and loudness. Choice reaction times were obtained for stimuli differing on one dimension alone, on two correlated dimensions, or on two orthogonally varied dimensions. Compared to one-dimension performance, reaction times were faster in the correlated condition and slower in the orthogonal condition. In general, these findings agreed with similar experiments in other modalities, with the exception that the effects in this study tended to be stronger for cases in which loudness, rather than pitch, was the relevant dimension. The results are explained in terms of the integrality of pitch and loudness and of the relative discriminability of dimensions.     

Isolating visual units in the perception of words and nonwords

In three experiments, reaction times for same-different judgments were obtained for pairs of words, pronounceable nonwords (pseudowords), and unpronounceable nonwords. The stimulus strings were printed either in a single letter case or in one of several mixtures of upper- and lowercase letters. In Experiment 1, the stimuli were common one- and two-syllable words; in Experiment 2, the stimuli included both words and pseudowords; and in Experiment 3, words, pseudowords, and nonwords were used. The functional visual units for each string type were inferred from the effects that the number and placement of letter case transitions had onsame reaction time judgments. The evidence indicated a preference to encode strings in terms of multiletter perceptual units if they are present in the string. The data .also suggested that whole words can be used as functional visual units, although the extent of their use depends on contextual parameters such as knowledge that a word will be presented.     

Texture size specificity in the slant aftereffect

Transfer of the median plane slant aftereffect was assessed across changes in stimulus texture size (sine-wave grating frequency). Under binocular viewing, reliable decrements in aftereffect magnitude were observed when texture size was changed, compared with no-change control conditions. Under monocular viewing conditions, no significant aftereffects were found. The results indicate a spatial-frequency-specific component of binocular slant aftereffects.     

Effect of perceptual cohesiveness on pattern recoding in the block design task

In the block design task, one type of intelligence test task, the subject reproduces a square-field pattern by assembling cubes having solid and diagonally divided surfaces. The task requires that the subject recode the perceived stimulus pattern into the alternatives available on the block surface. This experiment examined the effect on response or reproduction time of perceptual cohesiveness of pattern, quantified as the number of adjacent same-colored edges of cubes which abutt to form the pattern. This stimulus variable interacts with the type of design (quantified as total set size for designs constructed of all solid surfaces, all diagonally divided surfaces, or mixtures of the two types of surfaces) and with cuing (presence or absence on stimulus pattern of a superimposed grid congruent with block edges of the constructed design). Cohesiveness increases the difficulty of “mentally slicing” or recoding the pattern into the set of block alternatives. The psychological processes involved in recoding probably are the most important ones underlying the intelligence test task.     

Racial Mistrust and Deviant Behaviors Among Ethnically Diverse Black Adolescent Boys1

While it has been suggested that mistrust of the dominant White society may be an important protective factor for some members of racial minorities, the question of whether mistrust may also be related to nonnormative behaviors among minority members has not been explored. Using survey data from Miami, Florida, this study empirically tests this hypothesis among a sample of African American, Haitian, and other Caribbean island Black adolescent boys. Bivariate analyses suggest a strong relationship between racial mistrust and conventional forms of delinquency for all three ethnic groups. These findings also held in multivariate analyses in which six traditional predictors of deviance were statistically controlled. The authors conclude that racial mistrust adds a new dimension to empirical prediction models. In addition, they conclude that issues associated with racial mistrust should be considered when developing and implementing prevention strategies.     

Prevention education and substance abuse treatment

Relapse prevention is influenced by a number of variables including stress and negative mood states, motivation and commitment to abstinence, social support, physiological factors, withdrawal symptoms, and a repertoire of cognitive and behavioral strategies utilized in responding to the relapse process. Diverse theoretical approaches have emphasized conditioning models as well as information processing, cognitive and affective components of treatment, cognitive and behavioral coping responses, and a variety of other procedures. Outcome studies related to treatment have failed to consistently support the effectiveness of several of these components. To overcomes this, the authors advocate a single subject design in the study of these approaches. This article emphasizes the role of relapse prevention, and training and education in facilitating long-term abstinence, particularly with those intervention methods that are based on social learning theory and cognitive-behavioral models.     

A validational note on the revised Socialization Scale of the California Psychological Inventory

The revised (1987) Socialization Scale of the California Psychological Inventory was studied in a sample of 121 delinquent and nondelinquent males to determine if the revised scale, compared to the original version of the scale (1957), could differentiate among a group of nonoffenders and a comprehensive typology of offenders. Results of an ANOVA and product-moment correlations provided significant and considerable support for the discriminability of the revised So Scale. Obtained results indicate that the revised instrument can differentiate offenders from nonoffenders to about the same, or a greater, degree than the original scale.     

RELIGIOUS AND MYSTICAL STATES: A NEUROPSYCHOLOGICAL MODEL

Abstract. This paper first considers the current confusion in categorizing and even describing mystical states, including experiences of God, the Void, and lesser religious experiences. The paper presents the necessity of studying the neuropsychological substrate of such experiences both to understand them in greater depth and to help resolve scholarly confusion in this area. As a prelude to presenting a neuropsychological model, the basic principles of brain organization are reviewed, including hemispheri-city; primary, secondary, and tertiary sensory receptive areas; their motor analogues; prefrontosensorial polarity; and the integration of limbic functioning into cortical activity. A neuropsychological model for mystical states is then presented in terms of differential stimulation and deafferentation of various tertiary sensory association areas, along with integration of various patterns of limbic stimulation.     

Factorial validity of the 20-item Toronto Alexithymia Scale

The 20-item Toronto Alexithymia Scale (TAS-20) was developed in previous research to measure a general dimension of alexithymia with three inter correlated factors. These three factors reflect distinct facets of the alexithymia construct: (1) difficulty identifying feelings and distinguishing them from the bodily sensations of emotion, (2) difficulty describing feelings to others, and (3) an externally orientated style of thinking. This study tested the three-factor model for the TAS-20, using confirmatory factor analysis, in separate samples of young adults from Germany, Canada, and the United States. The previously established three-factor model was found to be replicable in all three samples. In addition, the full TAS-20 and its three factors demonstrated adequate internal reliability in all three samples. Although evaluation of the convergent, discriminant, and criterion validity of the TAS-20 is required in diverse cultural groups, the present results provide evidence for the factorial validity and internal reliability of the TAS-20.
